i can't GetmoduleHandleA("CShell.dll")?

here's my code:
#include<iostream>
#include<windows.h>
using namespace std;
int main(){

while (1){
if(GetModuleHandleA("CShell.dll")!=NULL){
cout<<"OK";
exit(-1);
}
}
}


when i run and ingame crossfire, it always NULL, i don't know why

By the looks of it, you're using console. I don't know with this. Try to change it to a dll.

Future info: you cannot get the base address of a program via externally. You'd have to enumerate all processes I believe. That code snippet is fine if used internally though.

just use
