Making a compiled Autohotkey script "generic" - compilation

When implementing “Image Search” within Autohotkey, the screen shot tucked away in folder in ..\MacroCreator\Screenshots.. under C:\Users\Rasstag...
If the intent is to develop a generic compiled script which can be used on PCs other than the developer, the path to 'screenshots' must not be an absolute path.
What would be the recommended approach to make a compiled script truly “generic”?
Any insight would be appreciated...

Per my comment,
EnvGet, Loc, USERNAME
Loc := Loc . "\MacroCreator\Screenshots"
Hth,

Look for "Built-in Variables" in the help files. They provide a lot of useful information. Find the group of variables listed under "Operating System and User Info."
Eg.
Name := A_UserName
MsgBox %Name%

Applescript/automator : move all the files listed in a document

I'm completely rebuilding a shared iTunes library and this needs to be team work.
I found a way to work the XML database in Google Drive so that we can all edit the track list simultaneously (>7500 entries). The spreadsheet contains for every song the path to the corresponding file.
Now I need a script to move the tracks listed in that spreadsheet to a common folder, so I can separate the songs we decided to keep from the ones we don't want anymore.
The blueprint I imagined for the code is basically :
Get the paths list (txt, csv, etc. doesn't matter) and store it as
an array.
Rotate through that array and select+move to a common folder each file pointed by the paths.
I'm not expecting any ready-to-use solution, but I would really appreciate some tips or pieces of advice that could make me spare a lot of time.
I also have to admit I have limited knowledge in Mac OS X programming (more used to web and windows environments) and have no experience in Applescripts.
However, I feel that what I'm trying to achieve is pretty straightforward and could help other people as well.
there are just 2 items not clear in your request :
1) what is the file type in which file paths are stored ? I assumed it is a text file
2) which format the paths have ? is it Unix format (like HD/Users/My_User/Desktop/My_Song), or is is a Finder format (like HD:Users:My_User:Desktop:My_Song). I assume it is a finder format
then script bellow asks you to select the text file, read it, ask you to select destination folder and move every file described in text file to the destination folder.
tell application "Finder"
set TextFile to (choose file with prompt "Select your text file" of type {"txt"})
set My_Folder to choose folder with prompt "Select your destination folder"
set List_files to paragraphs of (read TextFile)
move List_files to My_Folder
end tell
the "move" can be changed to a "copy", if required
Thank you so much to both of you for your answers.
Regarding pbell's questions :
1. I did not specify the format of the file containing the paths because I wasn't sure which ones the script could handle. Now I will make sure it is in a txt format.
2. The paths are actually il a Unix format, but seeing your example it looks pretty easy to parse. Can I just replace every "/" with a ":" ..?
I will try your code this afternoon. Again thanks a lot for caring and for sharing your time and knowledge.
Terence
Works like a charm !
Thank you very much pbell, your code works perfectly. I just had to make a txt file with Finder-formatted paths like so :
Macintosh HD:Users:FirstnameSurname:Desktop:Music:November-7:Season 3:04 Parasite.mp3
Macintosh HD:Users:FirstnameSurname:Desktop:Music:November-7:Season 3:05 Nowhere.mp3
Macintosh HD:Users:FirstnameSurname:Desktop:Music:November-7:Season 3:06 Amber Light.mp3
We spared so much time thanks to you.
Have a great day,
Terence

Set path in Visual Foxpro

I want to set path in Visual Foxpro. In such a way that I want to keep exe file on local machine and data\tables on server. How can I do so?
I personally have never liked using SET PATH, especially if you have many "paths" that your application is expecting to use.. If you have a given table / file in multiple locations that are visible with multiple paths that qualify, you may be getting the wrong table, but you won't necessarily know it since the application just runs as normal, finds a table and continues.
Instead, I would suggest one of a few things. Yes, have your application on each user's local machine, but have the person's shortcut have the "START IN" folder pointing to the path on the server where your data is. This way, your application will BE in the folder where the data resides and processes without issue. If no data is on the local machine, during your startup, you could add a messagebox about ... hey... your shortcut should be set to "Start In" setting to X:\SomeShareOnServer\MyVFPDataPath...
If not that, then another avenue I have used is to have your application during startup, add a property to the "_Screen" object which will NEVER loose scope, and set that property to the path you have the data located such as...
_Screen.AddProperty( "cDataPath" )
_Screen.cDataPath = "X:\SomeShareOnServer\MyVFPDataPath\"
Then, in your code, any of your opening tables or SQL queries, use the path variable PLUS the table... something like
if not used( "SomeTable" )
select 0
use ( _Screen.cDataPath + "SomeTable" )
endif
if doing a query, use similar approach
select ST.* ;
from ( _Screen.cDataPath + "SomeTable" ) ST ;
where ST.SomeID = 123;
into cursor C_TmpResult readwrite
So, although the second option may take more effort, especially on an existing application, the first option to make sure the "Start In" path is where the data is might help.
Again, this is my suggestion as I hate chasing down ambiguous -- sometimes it works, but not others. If I can't find a file, I WANT TO KNOW about it and fail outright.
Your call, your app, your environment. But if you DO use the "SET PATH" command, you might want to make sure you use the ADDITIVE command, just in case there are other settings, such as pointing to the a path for forms, classes, report folders... You run a SET PATH without it, and you kill your other paths...
SET PATH TO "X:\SomeShareOnServer\MyVFPDataPath\" ADDITIVE
Also, if you have any spaces in your path in question, MAKE SURE you use quotes around it, otherwise it will fail finding the path you expect and may cause compile error, such as
SET PATH TO X:\Some Share On Server\MyVFPDataPath\ ADDITIVE
You can use VFP's Set Path command
Set Path To m.lcDataFolder
early in your client startup code, i.e. in your project's "main.PRG".
Where the content of the m.lcDataFolder could for example come from something like a custom "myConfig.XML/INI/TXT" containing the desired string, e.g. \\fileServerNameOrIP\sharedDataFolder
Use 'SET DEFAULT TO' to change the current working directory or use explicit full paths as per the answer by #DRapp.

Porting MATLAB code from Windows to Mac

I have just switched from a PC to a Mac, and I am finding that lots of my MATLAB code previously written when I had a PC does not work on my Mac! I have been working on MATLAB for a while now, but I am not an expert yet.
After searching around for differences between PC and Mac, I noted that a few things indeed differed, but I'd love to hear about whether I need to go through all my yet written MATLAB code and update it manually to make it work on my Mac.
Please let me know what best to do here.
Example:
clear all
cd 'c:\users\sss\Desktop\MATLAB\project\DataFile\'
load data
cd ..
Why doesn't this work? Is it because of the backslash required for MATLAB on a Mac?
Of course, if you try to access a Windows-style path on a Mac, it will error.
MATLAB includes a set of functions that make it fairly easy to make your code cross-platform with respect to these sorts of issues. Take a look at, for example, the functions fullfile, fileparts, filesep, pathsep, ispc, and ismac.
I'm afraid that for the moment, you'll probably need to recode things to be either Mac-specific or to be cross-platform using the functions above.
One way is to have a path variables or variables set which determine where your data is held. You can even use computer or ismac and ispc to automatically switch to the correct version:
if ispc
dpath = 'c:\users\sss\Desktop\MATLAB\project\DataFile\';
elseif ismac
dpath = '/Users/sss/MATLAB/project/DataFile/';
end
load (fullfile(dpath, 'data.mat'));
If you have multiple files in subdirectories of /MATLAB/project/, you can set a project directory (similarly to matlabroot but pointing at where your files for that project are kept), and then use fullfile to select the correct subdirectory.
e.g. given a directory in proot that points to wherever /MATLAB/project/ is on the appropriate computer, these produce filenames which are in /MATLAB/project/data and MATLAB/project/output respectively:
datain = fullfile(proot, 'data','data.mat');
dataout = fullfile(proot,'output','output.mat');

How can I resolve MSI paths in VBScript?

I am looking for resolving the paths of files in an MSI with or without installing (whichever is faster) from outside an MSI, using VBScript.
I found a similar query using C# instead and Christpher had provided a solution, below: How can I resolve MSI paths in C#?
I am going through the very same pain now but is there anyway to achieve this using WindowsInstaller object in VBScript, rather than go with endless queries through SQL Tables of MSI back and forth to achieve the same. Though any direction would be welcoming as I have tried tested whatever I can with very limited success.
yes there is a solution without installing the msi and using vbscript.
there is a very good example in the Windows Installer SDK called "WiFilVer.vbs"
using that example i've thrown together an quick example script that does exactly what you need.
set installer = CreateObject("WindowsInstaller.Installer")
const READONLY = 0
set db = installer.OpenDataBase("<FULL PATH TO YOUR MSI>", READONLY)
set session = installer.OpenPackage(db, READONLY)
session.DoAction("CostInitialize")
session.DoAction("CostFinalize")
set view = db.OpenView("SELECT File, Directory_, FileName, Component_, Component FROM File,Component WHERE Component=Component_ ORDER BY Directory_")
view.Execute
set record = view.Fetch
do until record is nothing
file = record.StringData(1)
directoryName = record.StringData(2)
fileName = record.StringData(3)
if instr(fileName, "|") then fileName = split(fileName, "|")(1)
wsh.echo(session.TargetPath(directoryName) & fileName)
set record = view.Fetch
loop
just add the path to your MSI file.
tell me if you need a more detailed answer. i will have some more time to answer this in detail this evening.
EDIT the promised background (and why i need to call ConstFinalize)
naveen actually MSDN was the only resource that can give an definitive answer on this, but you need to know where and how to look since windows installer ist IMHO a pretty complex topic.
I really recommend a mix of the msdn installer function reference, the database reference, and the examples from the windows installer SDK (sorry couldn't find a download link, i think its somewhere hidden in the like 3GB windows SDK)
first you need general knowledge of MSIs:
an MSI is actually a relational database.
Everything is stored in tables that relate to each other.
(actually not everything, but i will try to keep it simple ;))
This database is interpreted by the Windows Installer,
this creates a 'Session'
also some parts are dynamically resolved, depending on the system you install the msi on,
like 'special' folders similar to environment variables.
E.g. msi has a "ProgramFilesFolder", where windows generally has %ProgramFiles%.
All dynamic stuff only exists in the Installer session, not the database itself.
In your case there are 3 tables you need to look at, take care of the relations and resolve them.
the 'File' table contains all Files, the 'Component' table tells you which file goes into which directory and the 'Directory' table contains all information about the filesystem structure.
Using a SQL Query i could link the Component and File table to find the directory name (or primary key in database jargon).
But the directory table has relations in itself, its structured like a tree.
take a look at this example directory table (taken from the instEd MSI)
The columns are Directory, Directory_Parent and DefaultDir
InstEdAllUseAppDat InstEdAppData InstEd
INSTALLDIR InstEdPF InstEd
CUBDIR INSTALLDIR hkyb3vcm|Validation
InstEdAppData CommonAppDataFolder instedit.com
CommonAppDataFolder TARGETDIR .
TARGETDIR SourceDir
InstEdPF ProgramFilesFolder instedit.com
ProgramFilesFolder TARGETDIR .
ProgramMenuFolder TARGETDIR .
SendToFolder TARGETDIR .
WindowsFolder_x86_VC.1DEE2A86_2F57_3629_8107_A71DBB4DBED2 TARGETDIR Win
SystemFolder_x86_VC.1DEE2A86_2F57_3629_8107_A71DBB4DBED2 WindowsFolder_x86_VC.1DEE2A86_2F57_3629_8107_A71DBB4DBED2 System
The directory_parent links it to a directory. the DefaultDir contains the actual name.
You could now resolve the tree by yourself and replace all special folders(which in a vbscript would be very tedious)...
...or let the windows installer handle that (just like when installing a msi).
now i have to introduce a new thing: Actions (and Sequences):
when running (installing, removing, repairing) an msi a defined list of actions is performed.
some actions just collect information, some change the actual database.
there are list of actions (called sequences) for various things a msi can do,
like one sequence for installing (called InstallExecuteSequence), one for collecting information from the user (the UI of the MSI: InstallUISequence) or one for adminpoint installations(AdminExecuteSequence).
in our case we don't want to run a whole sequence (which could alter the system or just take to long),
luckily the windows installer lets us run single actions without running a whole sequence.
reading the reference of the directory table on MSDN (the remarks section) you can see which action you need:
Directory resolution is performed during the CostFinalize action
so putting all this together the script is easier to read
* open the msi file
* 'parse' it (providing the session)
* query component and file table
* run the CostFinalize action to resolve directory table (without running the whole MSI)
* get the resolved path with the targetPath function
btw i found the targetPath function by browsing the Installer Reference on MSDN
also i just noticed that CostInitialize is not required. its only required if you want to get the sourcePath of a file.
I hope this makes everything clearer, its very hard to explain since it took me like half a year to understand it myself ;)
And regarding PhilmEs answer:
Yes there are more influences to the resolution of the directory table, like custom actions.
keeping that in mind also the administrative installation might result in different directorys (eg. because different sequence might hold different custom actions).
Components have conditions so maybe a file is not installed at all.
Im pretty sure InstEd doesnt take custom actions into account either.
So yes, there is no 100% solution. Maybe a mix of everything is necessary.
The script given by weberik (deriven from MS SDK VB code) is very good, because it makes it easy to analyse the directory table without an own algorithm (which is a mid-size effort to do it in a loop or with a recursion algorithm).
But it gives not a 100% perfect view for all files, see below.
The method of the script is semi-dynamic (can be extended by other actions), but in effect it gives only the static directory structure, similar to a default administrative install or advanced MSI viewers.
Normally this is enough and what we want.
But be aware, that this is not the 100% solution (Knowing before exact the path of each file afterwards). That does mean, this will not give you always the correct paths in some cases:
You use command line parameters which substitute predefined directory table entries.
The MSI uses custom actions which change paths.
Especially it is not guaranteed, that every file is installed. There may be optional conditions and features and this may depend on the install environment.
In effect, a 100% solution is very very hard to achieve, without installing really. It comes near to reprogram nearly the whole windows installer engine. So simplifications are normally sufficient and accepted.
But you can extend the method to cover custom actions, e.g. with adding a line "session.DoAction(..)" for each additional action needed. Or to include command line parameters.
Sometimes it can be tricky. The easier the structure of the MSI is, the more likely it is that you succeed without more efforts.
Alternative to write an own program:
The question is, what you really want to find out, and if it is really necessary to program it:
If you don't want to write an automatical every-day MSI analyzer maybe the following is sufficient for you:
First tip: install the MSI with "msiexec /a mysetup.msi TARGETDIR="c:\mytestpath" . (similar restrictions as script above by weberik)
If the MSI has not used custom actions to change pathes including forgetting to add to the admin sequence ("forgetting" should be taken as the normal case for 99% or existing setups :-), you get the filestructure like if you install "really" with some special namings for the Windows predefined folders which you will find out easily.
If the administrative install lacks some folders, it is often a better idea of fixing the custom action (adding to the admin sequence) and using this scenario as your primary test case.
The advantage is, that only you limit the dynamics used by admin install. BTW, you can use the same command line params or path settings custom actions as in real install.
Second tip: Google for the InstEd tool , go to the file or component table and you will see the resulting MSI paths in the same static way as with the mentioned VB-script after calling CostInitialize/CostFinalize. For human view such an editor view maybe better.
For automatic testing and improvements or accuracy, you need an own program of course.
For those of you that mentioned snippet given is a good starting point. :-)
The rest of you should live easier with one of the two given methods without programming.

How can I get the Name of the Program associated with a file extension using Delphi?

I need to get the name of the program currently associated with a file extension for the current user. If you right-click on a file and select properties, then what I need is the program name that is to the right of the "Opens with" line.
e.g. For ".xls", I want to be able to get the answer "Microsoft Office Excel", or whatever program the user has as their default program to open .xls files.
I have determined it's not as easy as just going into HKEY_CLASSES_ROOT and picking it out, since it may also be specified in HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER or HKEY_USERS.
Maybe all I need to know is the pecking order used by Windows to determine this and how to get to each of the locations. Of course, a Windows API call to do this would be ideal.
This is a similar question to:
How to get icon and description from file extension using Delphi? but that question only answered how to get the description of the extension and the icon of the associated program. I couldn't find a way to extend that to also get the name of the associated program.
I'm using Delphi 2009 and need a solution that works on Windows XP, Vista and 7.
Thank you all for your answers.
It appears my belief that the name of the executable is not in the Registry after all. And after looking around extensively for a Windows API that will give the name, I could not find one.
I think Mef's answer then is the best. To get the name of the executable from the information included in the program's executable.
Followup: I found David Hefferman's answer to "How do I open a file with the default text editor?" gives an excellent solution for opening one program using the default program for a different extension.
Don't go spelunking in the registry when there are API functions designed to do what you need.
In your case, you want AssocQueryString. You can give it the file-name extension, and it will tell your the program registered to handle that extension (AssocStr_Executable). If you're planning on running that program to open a document, then you'll really want the command string instead of just the executable; AssocQueryString can give you that, too (AssocStr_Command). It can also tell you the document type like what's displayed in Windows Explorer, like "Text Document" or "Zip Archive" (AssocStr_FriendlyDocName).
That API function is a wrapper for the IQueryAssociations interface. If you're looking for programs from many file types, or lots of strings associated with a single type, you may wish to instantiate that interface and re-use it instead of calling the API function over and over.
Delphi comes with a unit ShellApi.pas that is used in the sample code below. The file has to exist.
Here's how to use it:
function MyShellFindExecutable(const aFileName: string): string;
var
Buffer: array[0..WINDOWS.MAX_PATH] of Char;
begin
Result := '';
FillChar(Buffer, SizeOf(Buffer), #0);
if (SHELLAPI.FindExecutable(PChar(aFileName), nil, Buffer) > 32) then
Result := Buffer;
end;
Step 1
Get the executable which is assigned to a file extension, for instance with the following function:
uses Registry, Windows, SysUtils;
function GetAssociation(const DocFileName: string): string;
var
FileClass: string;
Reg: TRegistry;
begin
Result := '';
Reg := TRegistry.Create(KEY_EXECUTE);
Reg.RootKey := HKEY_CLASSES_ROOT;
FileClass := '';
if Reg.OpenKeyReadOnly(ExtractFileExt(DocFileName)) then
begin
FileClass := Reg.ReadString('');
Reg.CloseKey;
end;
if FileClass <> '' then begin
if Reg.OpenKeyReadOnly(FileClass + '\Shell\Open\Command') then
begin
Result := Reg.ReadString('');
Reg.CloseKey;
end;
end;
Reg.Free;
end;
(See here, or marc_s' anwser to this question :-)
Step 2
Now you can read out the name of the program from the version information of this executable! The easiest way is using the TVersionInfo class you can find via Google, for instance here.
var VersionInfo: TVersionInfo;
VersionInfo := TVersionInfo.Create('PathToExe\name.exe');
s := VersionInfo.KeyValue['Description'];
However, you have to be aware that some programs use the description key therefore (like RAD Studio itself or MS Excel), while others use the product name key...
I think that you need to combine Mef's and Rob Kennedy's answers.
Take Rob Kennedy's answer and take step 2 from Mef's answer. Reading registry directly isn't good thing to do, so you should throw away his part 1.
But I'm not looking for the friendly name of the file type.
AssocQueryString returns not only friendly name for file type (ASSOCSTR_FRIENDLYDOCNAME), but also it can return the name of executable to open file (ASSOCSTR_EXECUTABLE) - that is what you need.
Even more than that: I'm not sure, but may be ASSOCSTR_FRIENDLYAPPNAME will match your needs. In that case, you may use only Rob Kennedy's answer.
The problem with reading registry directly is that it may return wrong info. That's because you read system settings - that is what application registered. But user may override this. For example, he may right click on .xls and select "Open with..." -> "Other app." -> "OpenOffice" -> "Use this app always". Registration info for .xls type will not be altered (user preferences are saved in separate place, so apps can't mess with them), so your code (which reads registry directly) will continue to produce "MS Excel", even though when user double-clicks on file - OpenOffice will be launched.
How about this article here: Determining the associated application
In the concrete case of Excel, you will find the .xls extension under HKEY_CLASSES_ROOT - the default value of that entry is Excel.Sheet.8.
When you go search for Excel.Sheet.8 again in HKEY_CLASSES_ROOT, you'll find an entry with a default value of Microsoft Office Excel 97-2003 Worksheet - that's probably as good as it gets.
If the user says "use this app always" for .xls-files the info ist stored in
HK_CU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.xls
The key has an entry "Application" containing the Application name (e.g. "soffice.exe"). It's correlated to an Applcication key in HK_CR, e.g. HK_CR\Applications\soffice.exe\
