starting a windows executable via batch script, exe not in Program Files - windows

This is probably batch scripting 101, but I can't find any clear explanation/documentation on why this is happening or if my workaround is actually the solution. So basically any terminology or links to good sources is really appreciated.
So I have a program I want to execute via batch script (along with several other programs). It's the only one where the exe is not in a Program Files folder. I can get it to start like this:
C:\WeirdProgram\WeirdProgramModule\weirdmodule.exe
But I get an error along the lines of:
Run-time Error '3024':
Could not find file
C:\Users\MyUserName\Desktop\ModuleSettings.mdb
So it seems that the program is looking for its settings files from the same location that the batch script starts up. Given that I finally got everything to work by doing the following:
cd C:\WeirdProgram\WeirdProgramModule\
weirdmodule.exe
That works fine, and it's not the end of the world to have to go this route (just one extra line), but I've convinced myself that I'm doing something wrong based on lack of basic understanding.
Anybody know or can point me to why it works this way?
Oh, and doing the following:
start "C:\WeirdProgram\WeirdProgramModule\weirdmodule.exe"
doesn't do anything at all.
Thanks,

you are doing it perfectly :-)
the executable is probably looking for this file in the "current working directory", which is being set, when you "cd" to it before.
you can set your working directory manually by creating a shortcut to your batch file; right click; properties.
edit:
you can also set your current working directory using the start command:
start "Title" /D "C:\WeirdProgram\WeirdProgramModule\" "weirdmodule.exe"
edit:
If you like to pass params, just add them to the executable filename as you would in a regular shortcut:
start "Title" /D "C:\WeirdProgram\WeirdProgramModule\" "weirdmodule.exe" "param1 param2"
or
start "Title" /D "C:\WeirdProgram\WeirdProgramModule\" "weirdmodule.exe param1 param2"
For reference, the syntax is described here: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/ntcmds.mspx?mfr=true.

What's happening is that weirdmodule.exe is looking in the "current directory" for the .mdb file. You might be able to tell it where to find the .mdb file through a command line parameter or some other configuration method (registry or .ini file maybe). How you'd specify the location is entirely up to the weirdmodule.exe program, though.
Other than that, your current workaround is probably what you're stuck with.
As far as your problem with using start.exe... the start.exe program has the very, very odd behavior (bizarre behavior in my opinion) of treating the first parameter as the 'title' to put in the window if (and only if) the first parameter is in quotes. So you have a couple of options:
Don't use quotes to specify the program. This works for you because you don't need quotes (there aren't any spaces or other special characters in the path that would require quoting it):
start C:\WeirdProgram\WeirdProgramModule\weirdmodule.exe
Give an empty (or some other string) title as the first parameter. This is something you'd have to do if your path required quotes:
start "" "C:\WeirdProgram\WeirdProgramModule\weirdmodule.exe"

Bash Script How do I Open an Executable and Open multiple files within the executable?

My goal is to automatically open a few specific files from calling a bash script.
P:\ = personal directory
Approach 1:
Example Code Below (filename: test):
run "P:\Notepad++\notepad++.exe" "P:\test1.txt" "P:\test2.txt"
Question 1:
When I do "./test" in the bash shell, it opens up Notepad++.exe with test1.txt and says "P:\test2.txt" doesn't exist. Create it?"
I have both test1.txt and test2.txt in the P:\ drive so I'm not sure why "test2.txt" doesn't exist. Is it only allowed to take one parameter?
Approach 2:
I tried to use an array approach, but it's not working.
array = ("P:\test1.txt" "P:\test2.txt")
run "P:\Notepad++\notepad++.exe" $array[*]
Now it opens up Notepad++.exe with none of the files open and says "P:\test2.txt)" doesn't exist. Create it?"
echo ${ARRAY[0]} Prints the entire array as a string... not sure why
SOLVED See answer below.
Thanks all who helped. Any elegant approach/solution is appreciated too :)
Not sure about the parameters of the run command in bash, but it does seem like there is a need for a filler if you want to open multiple files within any executable.
Solution:
run "P:\Notepad++\notepad++.exe" "P:\test1.txt" "P:\test2.txt" ""
The "" is some kind of filler but ends up allowing you to open notepad++.exe and the two text files.
This is for automation purpose :) Hope it helps other users!

Why does one code execute from one folder but not the other?

I was just curious as to why with Windows O/S a simple Ruby file that prints one line to the command prompt can execute correctly from one path, but not the other.
Currently, I have said file in C:\Ruby193\test\lib saved inside the lib folder. When I go to the command prompt and set the path to C:\Ruby193\test\lib, I'd expect to see the code string be printed to the command prompt. However, nothing but an empty line is produced, and if I go up the path and set it to C:\Ruby193\test and execute the ruby file from there, it works just fine.
Does anyone have a sound explanation as to why it works that way? Would this also be the same case for a MAC O/S as well?

Build output from Visual Studio 2010 external tools in output window

I run a batch file as an external tool (by adding it in Tools->External tools) in VS2010 (I've checked the "Use Output Window" option). This batch file performs compilation as in VS command prompt. The project that I'm working on has makefiles for various folders, so I use the mk command to build.
In the batch file, I set up the VS environment and then run the following commands:
cd $directoryWhichContainsFileToBuild
mk
cd main //This directory contains the executable that is to be built
mk
I see the output of the first mk in the Output window but after that it just hangs. I also tried to use an echo after the first mk but even that doesn't get printed in the output window (the ones before it can be seen).
Somewhere I read that there is an issue with VS 2010 output window where it hangs after showing some output, although I couldn't really be sure that that is what's the issue here.
Do I need to enable some other VS setting? Has anybody else encountered this issue?
Thanks.
Update: I unchecked the "Use Output Window" and "Close on exit" option, and I see an extra statement: "Press any key to continue". On doing that however, their is no further processing of the batch file.
Update2: Got it to work by prefixing mk with "call".
Thanks all who tried.
It is always good in batch files to specify executables with full path and file extension instead of just the file name. This avoids often lots of problems.
Here was just mk used instead of mk.bat. Therefore on every compile the command line processor cmd.exe searches for mk.* and then checks if any of the found files have an extension listed in environment variable PATHEXT. The order of file extensions separated by a semicolon in PATHEXT defines the order of execution in case of a directory contains multiple mk.* files.
If a command being specified in a batch file not being an internal command of cmd.exe without path, command line processor searches first for a file with given name in current working directory. This is often one more cause of error. What is the current working directory on execution of the batch file?
Next if no file to execute can be found in current working directory, the command line processor searches in all folders being listed in environment variable PATH separated by semicolons.
So specifying in batch files edited only rarely an external application or another batch file with full path, file name and file extension, in double quotes if necessary because of 1 or more spaces in path or file name, helps command line processor to more quickly execute that application or batch file and avoids problems because of executable not found (unknown command).
Sure, when typing commands in a command prompt window, nobody wants to enter the executables with full path, name and extension. But for batch files it is always good to be not lazy and type files to be executed with full path and extension.
TripeHound has given already the explanation why the observed behavior occurred here.
If a batch file is executed from another batch file without using command call, the command line processor continues batch execution in the other batch file and does never come back. In a C/C++ program this is like using goto with the difference that parameters can be passed to the batch file containing the further commands to be executed next.
But running from within a batch file another batch file with call results in continuation of execution below the line calling the other batch file once the other batch file reaches end, except command exit is used in the called batch file without parameter /B.
So the solution here is using:
cd /D "Directory\Which\Contains\File\To\Build"
call "Path\Containing\Batch\File\To\Build\mk.bat"
rem With mk.bat not changing current working directory change working
rem directory to the directory containing the executable to be built.
cd main
call "Path\Containing\Batch\File\To\Build\mk.bat"
BTW: exit exits command processor, exit /B exits just current batch file. I'll give you three guesses why the parameter is B and not a different letter. Yes, B is the first letter of batch.
Writing as a separate answer instead of an update in the question itself as many readers see the header and skim to the answer: got it to work by prefixing mk with "call". (#TripleHound has also posted the conceptual reason for it in the comment above.)

Windows, ClearCase, and Ant: how to handle directory slashes?

I have a Windows batch script that I use to build a module and the script in turn uses the ClearCase clearmake command to drive the actual compilations, directory creations and file manipulations, i.e. process the Makefile content. The batch script works flawlessly when invoked using a DOS window or from a "cmd /c ..." command line invocation. And it has been that way for some number of years.
I recently decided to move the script to Ant. The first step, out of simplicity, was to simply invoke the script unchanged using an Exec task (using cmd /c). Almost immediately, Ant fails while creating a directory. The error message reports something like:
mkdir: Cannot create the directory C:\\fred\\harry\\joe
I was able to verify that, using the DOS command prompt, the mkdir C:\\fred\\harry\\joe command works fine, so, as near as I can tell so far, Ant generating double backslash path separators combined with something inherent to clearmake and/or something in the Makefile is causing the failure.
The response I'm looking for is something along the lines: "Yes, clearmake is definitely the culprit because..." or "If you twiddle this thing or that thing in Ant, only a single backslash will be generated...". Should there be no simple and quick explanation, I will drill into the problem to determine what exactly is causing the failure.
Thanks,
I have seen similar error with:
dynamic views (more sensible to ownership than a snapshot view on C:\, which is your case)
resource handle conflict (the script tries to update a resource already taken by another process, which shouldn't be the case here with your script, since it was working outside of Ant Exec task)
error message (like you create a directory which already exists: the error get ignored in a classic script, while it could interrupt the ant task.
While the last cause is a good candidate, try first to simplify your script (leave only the mkdir for instance) in order to check that this line is indeed the issue (nd not "this line in conjunction with others actions taking place just before")

CMD: Bat to Exe Converter - Temp directory problem

i am using 'Bat to Exe Converter' to convert my batch files to exe format.
Now, i am running into some problems.
Whenever i convert something, and i set 'Working Directory' to 'Current Directory', and i start my exe in echo on mode, this is what i end up with to check if there is a specific file in the directory of my exe:
the actual command: if not exist "%~dp0\file.txt" goto :nofile
output: if not exist "C:\Users\MyUser\AppData\Local\Temp\4CBC\\file.txt" goto :nofile
Can anyone help me with this? I don't want it in the temp directory, i want it to be in the directory of my exe.
Thanks.
Without having Bat to Exe changed by the author, I think you have two options:
Remove the need for accessing %~dp0
Perhaps you can merge file.txt with the include option of Bat to Exe into the EXE file. If so, "file.txt" will automatically be unpacked in the current directory when running your compiled exe, and you can it access by %CD%\file.txt.
Get %~dp0 from outside and pass it to the exe as a command line parameter.
This can be done by a simple starter bat file that resides in the same directory as your compiled main batch file. This script schould contain the line
YourCompiled.Exe %~dp0% %%*
Your compiled exe then gets its directory from %1. So you cannot pack everything into one exe, but the main portion of it, perhaps that is sufficient for you.
Well, apparently your batch to exe converter simply packs the batch file and extracts it to a temporary directory prior to execution. Very simplistic, hard to get wrong (compared to actually understand the batch file) but it introduces errors such as the one you're describing.
Your best bet is probably to use another batch to exe converter; some of them are actually a little more sophisticated.
Generally, this is not a good idea. firstly, its prone to errors and instability of the converter on different cmd features. secondly, a determined hacker can still decode what you are doing with the batch. My suggestion, if you are so afraid of people looking into your batch,
1) let only the people who are authorized to use your batch to use it
2) give them the correct permissions.
OR, don't use batch at all
1) create a central interface such as a web interface, where all tasks to be done goes through that interface, like using an ATM machine where only buttons are allowed and all the available user options can be done by pushing buttons...etc..
2) authenticate your users through a central authentication system, eg Active Directory, or LDAP or a database.
This is an 2.5 yr old subject but there is an answer to this so I'm posting for anyone else that happens to find this in a search.
B2EC written by Fatih Kodak, has an option to "Submit current directory".
When this is used, you can reference %1 in your batch file to get the path of the EXE that was executed (instead of the path of the extracted BAT that is really being run).
Hovering over that option in the UI shows "Submit the current working directory as the last parameter". The "last parameter" in my use has always been %1 but you can test your code to be sure.
The latest version, 2.1.4 at time of writing, of Bat to Exe by Fatih Kodak creates an Environmental Variable at runtime that can be substituted in place of %~dp0 to reference the Exe's path. Therefore, you can simply replace %-dp0 with %b2eprogrampathname% in the original batch file.
You can use external folders with f2ko's batch to exe converter. Having
a separate folder for subroutines can neaten up a project folder.
To call mysubroutine that is located in mysubroutinesfolder\mysubroutine,
...
pushd mysubroutinesfolder
call mysubroutine
popd
...
The call can be made a one liner:
call xqt mysubroutine
where xqt.cmd is a program that does the call for you:
pushd mysubroutinesfolder
call %*
popd
exit /b
(the %* means "all of the arguments").
In this way your batch programs run as batch, and UNMODIFIED they will
compile with the bat to exe converter, creating a completely folder independent executable. Select "temporary directory",
and include all of the subroutines/executables in your mysubroutines folder
by "selecting them all" with your cursor as usual, then hit "copy".
Be sure to include the xqt.cmd program too; place it "outside" of your mysubroutines folder. Make sure that is is accessible by your main program. Remember to select x64 if you
are runnning on a x64 machine, or the executable will not find SYSTEM32
files. You can find f2k0's batch to exe converter at:

%cd% will give you the current directory:
if not exist "%CD%\file.txt" goto :nofile
Use %CD% instead of %~dp0.
EDIT:
B2EC is not a real converter. Creation location of equipped .cmd file was chosen to be %TEMP% and this is a good choice. Application just lacks 3rd option for working directory of the script - .exe file directory. I advise you to mail the author about adding this one.
Different paths for .exe and created .cmd lead to information loss, i.e. we are unable to know .exe directory and current directory at the same time without providing additional information to the script (e.g. using environment variable or passing it as first/last argument to the script). This script would need to handle it and we would end writing cmd scripts tailored for this converter, which is bad.
%~dp0 - script directory (%TEMP%/.../) - practically useless
%cd% - working directory (as set up in the converter) - currently there are only 2 options: current directory (working directory of .exe) and temporary directory (actually equal to %~dp0, but without trailing backslash)
I think it can be solved by patching cmd.exe instance in memory to change the script path, but that's B2EC developer's duty.
Side note: Normal executable files can be easily executed with specified 0th argument by providing appriopriate lpApplicationName and lpCommandLine to CreateProcess function. Command files are executed via cmd.exe, so 0th argument cannot be set this way.
