Simple DLL displaying a Messagebox with custom text

Sindarin · #1 20-Jan-2009, 04:25

Hello, I am trying to create a DLL for practice which shows up a messagebox with a custom string but it doesn't work,

CPP / C++ / C Code:

#include "dll.h"
#include <windows.h>
#include <string>
using namespace std;

export double get_tab_key(char custommsg)
{
if(GetAsyncKeyState(VK_TAB))
{
MessageBox(0, custommsg, "Tab Message!", MB_OK | MB_ICONERROR);
}
return 1;
}

Now the custommsg is supposed to be a custom string. It seems that Messagebox doesn't like this though.

You are trying to pass to MessageBox a char - try a char array.

Best regards,
