hello, i have seen your post in this forum.i am very new to vc++. u also wrote this same code in this forum i saw.
TCHAR* GetPIDValue(TCH AR*);
TCHAR* GetPIDValue(TCH AR* lpszSourceDir)
{// For example, suppose the msi is located on a CD in the folder "\Setup\MySetup .msi".
// The user is running the CD in the D: drive.
// lpszSourceDir will have a value of "D:\Setup\" .
// Note that the trailing slash is included!

// TO DO: Concatenate key file path, example lpszSourceDir + "MyKeyFile. dat"
// TO DO: Read key file from source media
// TO DO: Code decryption algorithm for key file
// For this example, simply return a literal PID key of format <### - #######>
return "123 - 4567890";}
