problem related to files and directories
Hello all,
I have a directory called Dlls which is having some dll files. I need to copy all these files on client directory and also register them. The problem is that the number of dll files in the Dlls directory is not fixed and so I can't hardcode there names. I am wondering if there is a way to copy and register each file one by one from the directory without hard coding anything.
Right now my code is

File "Dlls\ms.dll"
File "UTSDlls\msis.dll"
………

Copyfiles /silent $INSTDIR\ms.dll "C:\Program Files\DLLS"
Copyfiles /silent $INSTDIR\msis.dll "C:\Program Files\DLLS"

…………………

RegDLL "C:\Program Files\DLLS\ms.dll"
RegDLL "C:\Program Files\DLLS\msis.dll"
…………………….

As you can see all the files in Dlls directory are copied by hard coding there names.

I would really appreciate if someone can help me out.
Thanks,
Lucky

Take a look at Locate in the NSIS Manual . You may use it to find all *.dll in a directory and then register each dll.

Thanks dude,
I can now copy all files but I am still not sure how to register dlls without hard coding there names.

Within the callback function that you pass to Locate, copy the file there and then register the file after copying it.

i didn't get what you wrote. Following is my code now

File "Dlls\*.dll"
Copyfiles /silent $INSTDIR\*.dll "C:\Program Files\DLLs"

My prob is what to write in
RegDLL "C:\Program Files\DLLs\?"

What you need to do is to look at Locate. Locate will allow you to search a directory (at runtime of your installer) for specific files and each time a file is found, you would just need to run RegDLL.

!include 'FileFunc.nsh'
!insertmacro Locate
...
Section Blah
    CopyFiles /silent $INSTDIR\*.dll "C:\Program Files\DLLs"

    #locates all dll's in C:\Program Files\DLLs
    ${Locate} "C:\Program Files\DLLs" "/L=F /G=0 /M=*.dll" LocateCallback
SectionEnd

Function LocateCallback
    #$R9 holds the absolute path of the file found
    #register the DLL
FunctionEnd

Thanks goldy1064
Now I have one last prob i guess. Following is my code now -

File "Dlls\*.dll"
${Locate} "$INSTDIR\" "/L=F /G=0 /M=*.dll" LocateCallback

Function "LocateCallback"
Copyfiles /silent $R9 "C:\DLLs"
RegDLL $R9
FunctionEnd

I have more then one dll files but this function is called I guess only one time so only one dll gets copied and registered. Can you help me understand what’s going wrong.

The below code can be used to continue searching until no more files/directories are found.

Function LocateCallback
   ...
   StrCmp $R9 "" 0 stop_locate
      Push ""
      goto end
   stop_locate:
      Push "StopLocate"
   end:
FunctionEnd
