Cant use my program when "special chars" are in name.

[BD9a]

Ok then..

User can expand list with currently opened windowNames. User choose windowName where my program have to work (click). Choosen windowName is converted to windowID to create hwnd of this window (hwnd is used in PostMessage function).

Now I have problem, because Window Name in target process had been changed, and have special chars (tbh idk what char).

Now I'm trying to use EnumWindows and get hwnd of this "broken" window. "If windowTitle contains (1some of this broken title && 2some of this broken title).

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam);

WINBOOL Conf::EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
    int length = GetWindowTextLength(hwnd);
    char* buffer = new char[length + 1];
    GetWindowTextA(hwnd, buffer, length + 1);
    std::string windowTitle(buffer);

    // List visible windows with a non-empty title
    if (IsWindowVisible(hwnd) && length != 0) {
        std::cout << hwnd << ":  " << windowTitle << std::endl;
        if(windowTitle.find("Minecraft") != std::string::npos && windowTitle.find("Pack.pl") != std::string::npos){
            g_hwnd = hwnd;
        }
    }
    return TRUE;
}

And if I trying to use EnumWindows(EnumWindowsProc, NULL); in other function, I got error: reference to non-static member function must be called

But when I changed this function to static, I have to change g_hwnd to static too, and if it's static idk how to use it here:

void Clicking::leftClick(){
    PostMessage(config->g_hwnd, WM_LBUTTONDOWN, 0, 0);
    PostMessage(config->g_hwnd, WM_LBUTTONUP, 0, 0);
}

It's probably a temp 'fix' and looking for some more universal.

I don't see anything in there which has something to do with Qt...

GetWindowTextA

That is the ASCII version, which fails on Unicode chars. Try GetWindowTextW for the wide character version...

When I just change GetWindowTextA to GetWindowTextW I got errors:

C:\Users\BD9a\Downloads\Minecraft-Clicker-master\Conf\conf.cpp:-1: In member function 'QStringList Conf::bumpNames()':

             GetWindowTextW(hwnd, title, length+1);

When I add GetWindowTextW(hwnd, (LPWSTR)title, length+1); In QML I got only one char per window.

@BD9a
Looks like you need to sort out your title definition/type? You can't just coerce to LPWSTR, it needs to be wchar_t in the first place....

Going back to your original code, now that you're going to call GetWindowTextW you can't stick with:

char* buffer = new char[length + 1];

:)

@JonB is fully right. The good thing is, that Windows wchar_t converts perfectly to QChar and from there to QString.

[BD9a]

But how to convert wchar_t* to QChar and next to QString?
I can only convert normal wchar_t

@BD9a
What about https://doc.qt.io/qt-5/qstring.html#fromWCharArray ?

Oh thanks, it working now.

Hi @BD9a,
