Hello dear community, i have the next problem, i would like to use a gui for my dll to display information and interact with the dll but i can't find a way of doing it. I know you can create a gui very easy with Qt but i dont know how to implement that to my dll. Does anyone know how to do it? I'd very thankful :)

You could use CLI its outdated but yea you can still implement a QT GUI inside a dll just use google first few links should have the answer.

You can also hook direct3d9 to make an "internal gui" lot of interisting stuff on google by searching "hook direct3d9 imgui" for example

This project uses Qt for external GUI in DLL that you can inject into game [Only registered and activated users can see links. Click Here To Register...]

I was just looking at that project when i saw your answer lol. Im trying to make a simple program dll with a gui but im getting a lot of errors. This is the code i want to work:
Code:
#include "mainwindow.h"
#include <windows.h>
#include <QApplication>

DWORD WINAPI DLLStart(LPVOID param)
{
    int argc = 0;
    QApplication app(argc, NULL);
    MainWindow window;
    window.show();
    app.exec();

    return 0;
}

void MyThread()
{
    // My code would be here
}


BOOL APIENTRY  DllMain(HINSTANCE hinstDLL, DWORD reason,LPVOID lpReserved)
{
    if (reason == DLL_PROCESS_ATTACH)
    {
        CreateThread(0, 0, DLLStart, 0, 0, 0);
        DisableThreadLibraryCalls(hinstDLL);
        CreateThread(0, 0, (LPTHREAD_START_ROUTINE)MyThread, 0, 0, 0);
    }
    return TRUE;
}
And this are the errors:

I just made a qt application and changed the main file

Then i have no idea what i'm doing wrong, in these case you used vs to compile it right?
10/01/2020 18:36 FI0w#10
yes i used vs with qt extension
10/01/2020 18:37 Hatz~#11
In my case i compiled directly from qt, i'll try that

EDIT: anyways i would also like to compile it directly from qt, any ideas? :)

the project from walrose is QT only, so no visual studio maybe you should check his project files.

Yup that project really helped me, now i understand how to do it but im getting a lot of erros i dont know why, and it's annoying af

In the project I've linked above you already have the .pro file. Just click it twice and Qt Creator should open up, check if it builds for you, don't create your own project.

Since the project was made on qt4 and im using qt5 i can't compile it :(
