Use Standard Acrobat to programmatically combine PDF file? - pdf-generation

There are lots of suggestions on SO and elsewhere for using non-Adobe products to programmatically combine PDF files.
Is there no way to (fairly easily) use my paid copy of Adobe Acrobat Standard (not Reader) to programmatically combine two or more PDF files into a new PDF file (I know it can be done manually with combine -> multiple files)?
Would prefer a command (e.g., copy file1.pdf file2.pdf combined.pdf), but would be willing to resort to VBA.
Thanks for any ideas!

Sub MergePDFs(nDocs As Integer, BaseFileName As String)
Dim AcroApp As Acrobat.CAcroApp
Dim iDoc As Integer
Dim BaseDocument As Acrobat.CAcroPDDoc
Dim PartDocument As Acrobat.CAcroPDDoc
Dim numPages As Integer
Set AcroApp = CreateObject("AcroExch.App")
Set BaseDocument = CreateObject("AcroExch.PDDoc")
Set PartDocument = CreateObject("AcroExch.PDDoc")
BaseDocument.Open (ActiveWorkbook.Path & "\" & BaseFileName & "_" & 1 & ".pdf")
For iDoc = 2 To nDocs
PartDocument.Open (ActiveWorkbook.Path & "\" & BaseFileName & "_" & iDoc & ".pdf")
numPages = BaseDocument.GetNumPages()
' Insert the pages of Part after the end of Base
If BaseDocument.InsertPages(numPages - 1, PartDocument, 0, PartDocument.GetNumPages(), True) = False Then
MsgBox "Cannot insert pages"
End If
PartDocument.Close
Next iDoc
If BaseDocument.Save(PDSaveFull, ActiveWorkbook.Path & "\" & BaseFileName & ".pdf") = False Then
MsgBox "Cannot save the modified document"
Else
' Remove intermediate documents
For iDoc = 1 To nDocs
Kill ActiveWorkbook.Path & "\" & BaseFileName & "_" & iDoc & ".pdf"
Next iDoc
End If
BaseDocument.Close
AcroApp.Exit
Set AcroApp = Nothing
Set BaseDocument = Nothing
Set PartDocument = Nothing
End Sub

There is no VBA for Acrobat. VBA is a Microsoft thing (and is apparently going away soon from what I've read [edit: strike that; apparently it's still alive and well in Office 2010]).
The Acrobat SDK will allow you to automate Acrobat and do what you want to do, but it's not for the faint of heart. It may be easier (short-term, anyway) to use one of the free solutions you've read about elsewhere.

VBScript: Move files to different folders depending on string in file name (For Each loop)

Original question:
I am quite unskillful with VBScript but would need an efficient solution for saving me lots of time selecting and copying files manually:
I have a folder with thousands raster files containing values of daily temperature for a certain area, altogether covering a period of 30 years.
In order to calculate monthly means out of 30 or 31 files per month (within a programme for geospatial data), I need to copy them into separate folders, e. g. the files from 2000 January 1 to 31 (named tx_20000101, tx_20000102 and so forth) into a folder named T_01_Jan_2000 and accordingly for all other months and years.
So I need a script, that searches for different text strings (YYYYMM) within all file names and moves the matched files into the given folder (for each search string a separate folder).
How could that be accomplished with VBScript?
With examples found in forums (mainly this: https://stackoverflow.com/a/29001051/6093207), I have come so far:
Option Explicit
Sub Dateien_verschieben()
Dim i
Dim FSO : Set fso = CreateObject("Scripting.FileSystemObject")
Dim Quelle : Set Quelle = FSO.GetFolder("C:\Users\…\Temperature")
Dim Ziel1 : Set Ziel1 = FSO.GetFolder("C:\Users\…\Temperature\T_01_Jan\T_01_Jan_2000")
Dim Ziel2 : Set Ziel2 = FSO.GetFolder("C:\Users\…\Temperature\T_02_Feb\T_02_Feb_2000")
…
Dim Ziel12 : Set Ziel12 = FSO.GetFolder("C:\Users\…\Temperature\T_12_Dez\T_12_Dez_2000")
Dim Str1, Str2, Str3, Str4, Str5, Str6, Str7, Str8, Str9, Str10, Str11, Str12
Str1 = "200001"
Str2 = "200002"
…
Str12 = "200012"
i = 0
For Each file in Quelle.files
x = fso.getbasename(file)
If instr(lcase(x), Str1) Then
i = i+1
If fso.fileexists(Ziel1 & "\" & file.name) Then
fso.deletefile Ziel1 & "\" & file.name, True
End If
fso.movefile Quelle & "\" & file.name, Ziel1
ElseIf instr(lcase(x), Str12) Then 'I have omitted the other ElseIf statements here for reasons of clarity
i = i+1
If fso.fileexists(Ziel12 & "\" & file.name) Then
fso.deletefile Ziel12 & "\" & file.name, True
End If
fso.movefile Quelle & "\" & file.name, Ziel12
End If
Next
If i>0 Then
wscript.echo i&" files moved to path " & vbcrlf & Quelle
wscript.quit()
End If
wscript.echo "No matches found"
End Sub
However, I get different errors like 800A0414 and 800A0046, and did not get the script running yet as intended.
Any suggestions for correcting the code or for more efficent ways of scripting are welcome.
Edited question:
Having a folder with several thousands netCDF-files containing values of daily temperature for a certain area, altogether covering a period of 30 years, how is it possible to move them into separate folders monthwise?
The month folders should contain subfolders for the respective year.
So the files are named tx_20000101.nc, tx_20000102.nc and so forth and are altogether in the folder Temperature.
Now all files from January should come into a folder name T_01, which contains subfolders named T_01_1991, T_01_1992 and so on, accordingly for all other months and years.
How can this be accomplished by VBScript?
The solution (thanks to #Les Ferch):
Move = True 'Set to False for Copy
SrcDir = ".\Temperature" Set oFSO = CreateObject("Scripting.FileSystemObject")
Set Source = oFSO.GetFolder(SrcDir)
For Each File in Source.Files
FileName = Right(File,11)
YYYY = Mid(FileName,1,4)
MM = Mid(FileName,5,2)
MonthDir = SrcDir & "\T_" & MM & "\"
YearDir = MonthDir & "T_" & MM & "_" & YYYY & "\"
If Not oFSO.FolderExists(MonthDir) Then oFSO.CreateFolder(MonthDir)
If Not oFSO.FolderExists(YearDir) Then oFSO.CreateFolder(YearDir)
If Move Then oFSO.MoveFile(File),YearDir Else oFSO.CopyFile(File),YearDir
Next

Trying to query a text file in Excel VBA on Mac OS X

I must be crazy for trying to use Excel (2015? It says copyright 2015) VBA on OSX. I'm trying to have Excel query some text files, called 33.txt, 34.txt, etc. in the same folder as my workbook. It chooses the file according to numbers in Column A. Excel gives me this error message: "Excel cannot find the text file to refresh this external data range.Check to make sure the text file has not been moved or renamed, then try the refresh again."
fileloc = ActiveWorkbook.Path & "/" & Range("A" & j) & ".txt"
With ActiveSheet.QueryTables.Add(Connection:="TEXT;" & fileloc, Destination:=Range("P1"))
.AdjustColumnWidth = False
.RefreshStyle = xlOverwriteCells
.Refresh BackgroundQuery:=False
End With
To make matters more frustrating, when I debug.print fileloc, it looks right. It looks like the exact location of the text file I want it to query.
Oh man I got it, with help from here: VBA: .Refresh Run-Time Error
' Get the URL
fpath = ActiveWorkbook.Path
f_dummy = fpath & "/" & Range("A" & j) & ".txt"
fname = Dir(f_dummy)
With ActiveSheet.QueryTables.Add(Connection:="TEXT;" & fpath & "/" & fname, Destination:=Range("P1"))
.AdjustColumnWidth = False
.RefreshStyle = xlOverwriteCells
.Refresh 'BackgroundQuery:=False
End With

Populate GPO from Text File using VBScript or other

Ok, so we need to create a GPO that allows our users to only use specific programs.
GPO Location:
User Configuration
Policies
Administrative Templates [...]
System
Run only specified Windows applications
Then setting the GPO to enabled and clicking on List of allowed applications --> Show...
I have created an excel spreadsheet containing the names of all the programs and their associated executable files with other pertinent information so that we can easily organize, add, delete, etc. the executable files that we need to allow our users access to.
This spreadsheet then dumps all the executable files into a text file.
Here is an example of what the text file looks like:
Acrobat.exe
chrome.exe
calc.exe
.
.
.
There are a lot of entries and these are likely subject to change. What I am trying to do is create a script that will take that text file and populate the GPO automatically. I don't care if we have to open the window and then run it, it does not need to run from the task scheduler (although that would be amazing if someone has that code ready). We just need it to populate this ridiculous amount of executable filenames into the fields.
Here is code I found (VBScript) that when run, should populate the fields automatically, however I cannot get it to run in the Group Policy Management Editor (it runs in the windows explorer window instead and ends up searching for some of the files)
' Open the text file, located in the same path as the script
Set objFSO = CreateObject("Scripting.FileSystemObject")
strPath = Mid(Wscript.ScriptFullName, 1, InStrRev(Wscript.ScriptFullName, wscript.ScriptName) -1)
Set objFile = objFSO.OpenTextFile(strPath & "appList.txt")
' Activate the "Show Contents" window with the "List of allowed applications".
' Note the window must be opened already and we should have selected where in
' the list we want to enter the data before running the script
set WshShell = WScript.CreateObject("WScript.Shell")
WScript.Sleep 1000
WshShell.AppActivate "Show Contents"
' Read the file line by line
Do While objFile.AtEndOfStream <> True
' Each line contains one EXE name
exeName = objFile.ReadLine
' Escape forbidden chars { } [ ] ( ) + ^ % ~
exeName = Replace(exeName, "[", "{[}")
exeName = Replace(exeName, "]", "{]}")
exeName = Replace(exeName, "(", "{(}")
exeName = Replace(exeName, ")", "{)}")
exeName = Replace(exeName, "+", "{+}")
exeName = Replace(exeName, "^", "{^}")
exeName = Replace(exeName, "%", "{%}")
exeName = Replace(exeName, "~", "{~}")
' Send the EXE name to the window
WScript.Sleep 100
WshShell.SendKeys exeName
' Move to the next one
WshShell.SendKeys "{TAB}"
Loop
objFile.Close

"C:\Windows\System32\GroupPolicy\User\Registry.pol"
Is where my policies are stored. It's a semi text file. Try writing to that file.
Ok, so I tried it many different ways. If anyone is looking for an answer to do this, this is the way I've figured it out and the way I've decided to proceed. I will post all relevant code below.
In Excel, the format of my table is as follows:
(With obviously WAY more entries)
Here is the VBA code I used to turn the data from this file into the proper format for the registry key:
VBA - In Excel
Public Sub ExportToTextFile(FName As String, _
Sep As String, SelectionOnly As Boolean, _
AppendData As Boolean)
Dim WholeLine As String
Dim FNum As Integer

End With
Else

StartCol = .Cells(2).Column
EndRow = .Cells(.Cells.Count).Row
EndCol = .Cells(2).Column
End With
End If
If AppendData = True Then

End If

WholeLine = ""
For ColNdx = StartCol To EndCol
If Cells(RowNdx, ColNdx).Value = "" Then
CellValue = ""
Else
CellValue = Cells(RowNdx, ColNdx).Value
End If
WholeLine = WholeLine & Chr(34) & CellValue & ".exe" & Chr(34) & "=" & Chr(34) & CellValue & ".exe" & Chr(34) & Sep
Next ColNdx
WholeLine = Left(WholeLine, Len(WholeLine) - Len(Sep))
Print #FNum, WholeLine; ""
Next RowNdx
EndMacro:
On Error GoTo 0
Application.ScreenUpdating = True
Close #FNum
End Sub
Sub PipeExport()
Dim FileName As Variant
Dim Sep As String
FileName = Application.GetSaveAsFilename(InitialFileName:="appList", filefilter:="Text (*.txt),*.txt")
If FileName = False Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Sep = "|"
If Sep = vbNullString Then
''''''''''''''''''''''''''
' user cancelled, get out
''''''''''''''''''''''''''
Exit Sub
End If
Debug.Print "FileName: " & FileName, "Extension: " & Sep
ExportToTextFile FName:=CStr(FileName), Sep:=CStr(Sep), _
SelectionOnly:=False, AppendData:=False
End Sub
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
PipeExport
End Sub
The file that is created is appList.txt and its format is the same format as the registry key:
"Acrobat.exe"="Acrobat.exe"
"AcroRd32.exe"="AcroRd32.exe"
Now in your GPO, add a unique program name to the allowed applications list (say test1234.exe) and in your registry editor, go to Edit > Find test1234.exe.
Export that registry key under File > Export. Remove the test1234.exe line and paste in your text file. Then reimport that file and you're done!

How do I save an entire VB6 project to a new folder? Modules and all

How do I save an entire VB6 project to a new folder? Modules and all. I'm in a position where I need to work with some old VB6 projects. I'd like to save them to a new folder but when I save the project, all that is saved is the vbp file. No modules, no frm files. I want to be able to save all the info to a single folder without moving each BAS file one at a time. Is this even possible?
Addition: The first 2 replies make good sense. But my problem is that the BAS modules seem to be scattered all over the place. Making Windows Explorer do the work a bit tricky. If I have to I will but was looking for an easier way.
Thanks
Given the new "addition" to the question:
Move the VBP and the files in Windows Explorer to a completely new directory.
Open the VBP in a text editor and change any absolute paths to relative paths. VBP files are simple text files, and the format is even documented in the VB6 manual.
Here's an example. This evil VBP below has many absolute paths
Type=Exe
Form=c:\who\knows\where\B_Form.frm
Module=CModule; z:\magic\mapped\network\drive\heehee\C_Module.bas
Class=DClass; x:\personal\usb\stick\D_Class.cls
It would be changed to this benign VBP, which references local copies of the files. You can use relative paths for subdirectories.
Type=Exe
Form=B_Form.frm
Module=CModule; C_Module.bas
Class=DClass; subdirectory\D_Class.cls
If you mean from within Visual Studio, I don't think you can except by doing Save As for each file...
But the simpler approach is to just use Windows Explorer and copy the whole folder structure for the solution into another folder, (or do a recursive "Get" from your source code repository to a different local destination), and then open the solution or project file in the new location... The pointers in the project file that tell Visual Studio where 5all the individual source code and other files are located are generally all stored as relative paths, relative to the folder that the project file is in...
It's been a while since I used VB6, but I'd be tempted to move them using Windows Explorer, then manually edit the VBP file to point to the new locations afterwards. If I remember right, relative paths are fine in the VBP, so you may not even need to manke any changes.
Unbind from source control, if capable/appropriate.
Check into source control as a brand new solution/project
Recursive 'get' from your SCM into a new directory.
There's your new copy.

Can Windows' built-in ZIP compression be scripted?

Is the ZIP compression that is built into Windows XP/Vista/2003/2008 able to be scripted at all? What executable would I have to call from a BAT/CMD file? or is it possible to do it with VBScript?
I realize that this is possible using WinZip, 7-Zip and other external applications, but I'm looking for something that requires no external applications to be installed.
There are VBA methods to zip and unzip using the windows built in compression as well, which should give some insight as to how the system operates. You may be able to build these methods into a scripting language of your choice.
The basic principle is that within windows you can treat a zip file as a directory, and copy into and out of it. So to create a new zip file, you simply make a file with the extension .zip that has the right header for an empty zip file. Then you close it, and tell windows you want to copy files into it as though it were another directory.
Unzipping is easier - just treat it as a directory.
In case the web pages are lost again, here are a few of the relevant code snippets:
ZIP
Sub NewZip(sPath)
'Create empty Zip File
'Changed by keepITcool Dec-12-2005
If Len(Dir(sPath)) > 0 Then Kill sPath
Open sPath For Output As #1
Print #1, Chr$(80) & Chr$(75) & Chr$(5) & Chr$(6) & String(18, 0)
Close #1

Yes, this can be scripted with VBScript. For example the following code can create a zip from a directory:
Dim fso, winShell, MyTarget, MySource, file
Set fso = CreateObject("Scripting.FileSystemObject")
Set winShell = createObject("shell.application")
MyTarget = Wscript.Arguments.Item(0)
MySource = Wscript.Arguments.Item(1)
Wscript.Echo "Adding " & MySource & " to " & MyTarget
'create a new clean zip archive
Set file = fso.CreateTextFile(MyTarget, True)
file.write("PK" & chr(5) & chr(6) & string(18,chr(0)))
file.close
winShell.NameSpace(MyTarget).CopyHere winShell.NameSpace(MySource).Items
do until winShell.namespace(MyTarget).items.count = winShell.namespace(MySource).items.count
wscript.sleep 1000
loop
Set winShell = Nothing
Set fso = Nothing
You may also find http://www.naterice.com/blog/template_permalink.asp?id=64 helpful as it includes a full Unzip/Zip implementation in VBScript.
If you do a size check every 500 ms rather than a item count it works better for large files. Win 7 writes the file instantly although it's not finished compressing:
set fso=createobject("scripting.filesystemobject")
Set h=fso.getFile(DestZip)
do
wscript.sleep 500
max = h.size
loop while h.size > max
Works great for huge amounts of log files.
Just for clarity: GZip is not an MS-only algorithm as suggested by Guy Starbuck in his comment from August.
The GZipStream in System.IO.Compression uses the Deflate algorithm, just the same as the zlib library, and many other zip tools. That class is fully interoperable with unix utilities like gzip.
The GZipStream class is not scriptable from the commandline or VBScript, to produce ZIP files, so it alone would not be an answer the original poster's request.
The free DotNetZip library does read and produce zip files, and can be scripted from VBScript or Powershell. It also includes command-line tools to produce and read/extract zip files.
Here's some code for VBScript:
dim filename
filename = "C:\temp\ZipFile-created-from-VBScript.zip"
WScript.echo("Instantiating a ZipFile object...")
dim zip
set zip = CreateObject("Ionic.Zip.ZipFile")
WScript.echo("using AES256 encryption...")
zip.Encryption = 3
WScript.echo("setting the password...")
zip.Password = "Very.Secret.Password!"
WScript.echo("adding a selection of files...")
zip.AddSelectedFiles("*.js")
zip.AddSelectedFiles("*.vbs")
WScript.echo("setting the save name...")
zip.Name = filename
WScript.echo("Saving...")
zip.Save()
WScript.echo("Disposing...")
zip.Dispose()
WScript.echo("Done.")
Here's some code for Powershell:
[System.Reflection.Assembly]::LoadFrom("c:\\dinoch\\bin\\Ionic.Zip.dll");
$directoryToZip = "c:\\temp";
$zipfile = new-object Ionic.Zip.ZipFile;
$e= $zipfile.AddEntry("Readme.txt", "This is a zipfile created from within powershell.")
$e= $zipfile.AddDirectory($directoryToZip, "home")
$zipfile.Save("ZipFiles.ps1.out.zip");
In a .bat or .cmd file, you can use the zipit.exe or unzip.exe tools. Eg:
zipit NewZip.zip -s "This is string content for an entry" Readme.txt src
There are both zip and unzip executables (as well as a boat load of other useful applications) in the UnxUtils package available on SourceForge (http://sourceforge.net/projects/unxutils). Copy them to a location in your PATH, such as 'c:\windows', and you will be able to include them in your scripts.
This is not the perfect solution (or the one you asked for) but a decent work-a-round.
to create a compressed archive you can use the utility MAKECAB.EXE
