script error - how to put double quotes within the second parameter of FILE.RUN

[rachelgeo]

Hi,

i wanted the installation of my program to execute regasm.exe to register a .dll file. the dll file is stored in c:\program files\common files folder.

the syntax of regasm.exe is
regasm /codebase /tlb "c:\program files\common files\drt.dll"

in regasm, the source path of dll file should be in double quotes if it contains any space between characters.
this has created problem for me.

how do i put double quotes in the second parameter in File.run action?

if i change the path of dll to c:\rrr\drt.dll and execute the below code, it works perfectly well.

on post install event, i wrote the following code

result = File.Run(SessionVar.Expand("%AppFolder%\\regasm.ex e"), "/codebase /tlb C:\\rrr\\drt.dll", "", SW_SHOWNORMAL, true);
error = Application.GetLastError();
-- If an error occurred, display the error message.
if (error ~= 0) then
Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION);
end

this works. but i want to change the path of my dll file to "c:\program files\common files\drt.dll" .

what change shud i do in the above code?

Thanks

hello again,

in the above code, i want to use %commonfilesfolder% session variable instead of specifying the path "c:\program files\common files\drt.dll" . directly.

Try this:

result = File.Run(SessionVar.Expand("%AppFolder%\\regasm.exe"), "/codebase /tlb \"" .. SessionVar.Expand("%CommonFilesFolder%") .. "\\drt.dll\"", "", SW_SHOWNORMAL, true)

In scripting language, you often need to escape some characters in order for the scripting engine to know what you are doing. Characters that often need to be escaped are " \


example:

strMyVar = "C:\\Some Directory\\Another Directory";

Here, the variable value would end up being...

C:\Some Directory\Another Directory



Another example:

strMyVar = "\"C:\\Some Directory\\Another Directory\"";

Here, the variable value would end up being...

"C:\Some Directory\Another Directory"



Another example:

strMyVar = "1234\"0000\"5678";

Here, the variable value would end up being...

1234"0000"5678


Hope this helps.

Single quote 'asdfa'

So if you need the double "in the string". you would do

'/E "C:\\Progam files\\my program\\my program.exe"'

That would pass

/e "C:\Progam files\my program\my program.exe" out of lua
