You need to strip the path from szModule and i recommend stricmp because the charcase could be different

| Alright after some investagating, I found out the process name was too long for me to read, I tried googling for the problem but came up with nothing. Any help would be appreciated!

Some notes about your function:
- The name you pass to the function can be const char* instead of just char*.
- You are opening a handle and never closing it.
- You should check the return of Module32First to ensure it didn't fail.
- strcmp is case-sensitive, check out strnicmp instead.
Also if you are looking for a specific module, there is no reason to use 'TH32CS_SNAPALL'. Instead, you should use TH32CS_SNAPMODULE or TH32CS_SNAPMODULE32 specifically.

Hey atom0s thanks for replying, I have edited my code and took your advice. I dont understand why I cant get the process module, I can get the processID just fine with my other function
| Code: |
DWORD GetPID(char* procName)
{
HANDLE handle = CreateToolhelp32Snapshot(TH32CS_SNAPALL,0);
PROCESSENTRY32 procEnt;
procEnt.dwSize = sizeof( PROCESSENTRY32 );
Process32First(handle,&procEnt);
do {
if( strcmp(procEnt.szExeFile,procName) == 0 )
{
return procEnt.th32ProcessID;
}
}while( Process32Next(handle,&procEnt) );
CloseHandle(handle);
return 0;
}
|
But for some reason this game only, I cannot get the module. I never have run into this problem which is why I'm so confused. I mean it seems to me that the strcmp is not the problem because it can get the PID but I dont know 
In cheat engine the pointer shows up just fine

Is the process you are targeting 64bit?

yes
| Code: |
DWORD base = GetBaseAddr(pid,"launcher64.exe");
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE,
pid);

is your code compiled as a 64-bit process as well? If not, it won't be able to target that process
