How to find a string in Specific Position

For eg.) MyStr = "Testing"

If I pass parameter 4 to some function, it should return 't'. Anyway it can be done in install script?

Rayner,

There are a lot of ways you could do it using InstallScript String Functions

Here is one example using CopyBytes
http:// helpnet.flexerasoftware.com/installshield21helplib/Subsystems/installshield21langref/helplibrary/LangrefCopyBytes.htm

//-------------------------------------------------------------------------

prototype STRING ExFn_CopyBytes( byval STRING,	// szMyString
				byval NUMBER );	// nPos


// szMyString = the string you are searching
// nPos = the position in the string that you want
function STRING ExFn_CopyBytes( szMyString, nPos )
    STRING szFoundStr;
begin

	// use 'number - 1' because CopyBytes is 0-based.
	// passing "4" to find the "t" in "Testing" would actually be position 3
	CopyBytes( szFoundStr, 0, szMyString, nPos - 1, 1 );
	
	return szFoundStr;

end;
