I want to call an WindowsAPI function from InstallShield.
How can I call the GetUserName
WinAPI function?

Hi There.

I have solved the problem :)))

To call the Windows API From IS:
**********************************************
// your DLL function prototypes (AT the top of the setup.rul)
prototype LONG advapi32.GetUserNameA(BYREF STRING, BYREF LONG);

//To use the function above (GetUserNameA)
STRING svUserName;
LONG nvLength, nvResult;
nvLength = 256;

nvResult = GetUserNameA(svUserName, nvLength);
MessageBox(svUserName, SEVERE);
****************************************************

The above works for all OS.

Hello Again.

Here is a better API function to get information about
CurrentUser, Domain, PrfileString,  SystemDrive,
SystemRoot, CurrentOs and more...

***********************************************************
//At the top of the
prototype LONG   kernel32.GetEnvironmentVariable(BYVAL STRING, BYREF STRING, BYREF LONG);

//Calling the API Function.
STRING szUserProfile;
LONG nvLength;
nvLength = 256;
nvResult = GetEnvironmentVariable("Userprofile",
szUserProfile, nvLength);
MessageBox(szUserProfile, SEVERE);

***********************************************************
