    As said in the title... I want to make an app that reads GPU Voltage thru Riva.

    Here's my test-app:
    Code:
    #include <windows.h>
    #include <iostream>
    #include "RivaTunerExports.h"
    using namespace std;
    
    READ_I2C_EX_PROC ReadI2CEx = NULL;
    GET_HOST_APP_VERSION_PROC GetHostAppVersion = NULL;
    GET_I2C_BUS_NUM_EX_PROC GetI2CBusNumEx = NULL;
    
    int main(int argc, char**argv) {
    	HMODULE hRiva = LoadLibrary("C:\\Program Files (x86)\\RivaTuner v2.24\\RivaTuner.exe");
    	if(hRiva)
    		cout << "RivaTuner successfully found and loaded." << endl;
    	GetHostAppVersion = (GET_HOST_APP_VERSION_PROC)GetProcAddress(hRiva, "GetHostAppVersion");
    	GetI2CBusNumEx = (GET_I2C_BUS_NUM_EX_PROC)GetProcAddress(hRiva, "GetI2CBusNumEx");
    	ReadI2CEx = (READ_I2C_EX_PROC)GetProcAddress(hRiva, "ReadI2CEx");
    	if(!(GetHostAppVersion && GetI2CBusNumEx && ReadI2CEx)) {
    		cout << "Error locating function pointers" << endl;
    		return 1;
    	}
    	cout << "Version: " << GetHostAppVersion() << endl;
    	BYTE test = NULL;
    	if(ReadI2CEx(0, 0x01, 0x70, 0x18, &test))
    		cout << "Data: " << (int*)test << endl;
    	else
    		cout << "FAIL" << endl;
    	return 0;
    }
    
    Any way to get this to work (without turning it into a DLL plugin)? Currently, it crashes upon reaching the call to the ReadI2CEx function.

    As I said, it's a test-app, so I did not code a GUI for it just yet, so I'm using Win32 Console.

    You cannot load an executable file with LoadLibrary, it won't work.

    So I'll have to resort to attaching to the process?
