Thread: How to set pointer for environment variable

I have 2 loaders (loader1 and loader2). I also have a Pinger which depends on the call i give will execute either loader1 or loader2. I have problem that the pointer strloaderPath. The problem like you see below if i call loader1 this program will execute loader by getting the environment variable. So the first time I call loader1 strloaderPath will get the env variable which will be c:\program Files\ then it will use strcat to add loader1.exe to execute it. Now if i want to execute loader2 when strloaderPath get the environment variable it will get it wrong it will get c:\program files\loader1.exe which is wrong because it should only get c:\program files then if i do strcat it should show c:\program files\loader2.exe and not c:\program files\loader1.exe\loader2.exe
