**NEWBIE QUESTION**

I have a question regarding variable replacement in a text file. In this instance, I am prompting the user for IP address and Port number, and have created dialogs for that. I have defined variables in the InstallScript to hold those values for later use. The intention is to take those values and insert them into an IIS "web.config" file.

Inside of this file I have the replacable text in this form exactly:

<add key="LoginMode" value="[SITETYPE]" />

The [SITETYPE] reflects a variable defined in the script and is tied to the Setup Type. Overall, the setup runs fine except the variables do not get replaced in the script. I do not know what I am doing wrong. (See script segments below).

#define DEFAULT_IPADDRESS "0.0.0.0"
#define DEFAULT_PORT "0000"

#define SETUPTYPE_MSG "Please select your setup type based on your environment."
#define SOURCE_DIR "C:\inetpub\wwwroot\WBCServices\\"
#define SOURCE_FILE "web.config"

//Find and replace operation 1: SITETYPE

FileGrep ( SOURCE_DIR ^ SOURCE_FILE , "[SITETYPE]" , svReturnLine , nvLineNumber , RESTART );
nLength = StrLengthChars( svReturnLine );
nStart = StrLengthChars( "<add key=\"LoginMode\" value=\"svSiteType\"/>");

//Find and replace operation 2: SERVERIP

FileGrep ( SOURCE_DIR ^ SOURCE_FILE , "[SERVERIP]" , svReturnLine , nvLineNumber , RESTART );
nLength = StrLengthChars( svReturnLine );
nStart = StrLengthChars( "<add key=\"VistaServer\" value=\"svIP\"/>");

//Find and replace operation 3: SERVERPORT

FileGrep ( SOURCE_DIR ^ SOURCE_FILE , "[SERVERPORT]" , svReturnLine , nvLineNumber , RESTART );
nLength = StrLengthChars( svReturnLine );
nStart = StrLengthChars( "<add key=\"VistaPort\" value=\"svPort\"/>");

// Close the file.
if (CloseFile (nvFileHandle) < 0) then
MessageBox ("CloseFile failed.", SEVERE);
end;

If anyone can help, I would appreciate it.

This should be:
#define SOURCE_DIR "C:\\inetpub\\wwwroot\\WBCServices\\"

Also I don't see where you are actually replacing the text?

You may also want to look at the sample code "Replace a String in a File" at http://www.installsi.../en/isp_str.htm

Thanks Stefan, I'll try that out shortly. It makes sense that if IS can't find the right file no edits can be made...
