Qt app: Create a shell link to my app with a pixmap as the link icon

Hi,

I have a Qt app and I need to save in runtime a link to my .exe file (with some arguments) in user desktop The icon must be a pixmap I have in runtime. Can I use this pixmap somehow as the link icon or must I save the pixmap to a .ico file?

Another doubt: when I create the link with an icon path my app icon is changed to that icon... Can I avoid it? I want an icon for the link different from my app icon

I am (successfully) creating a link with this snipped code:

Code:

---

QString sPathTarget = [MY_EXE_PATH];
QString sLinkName = "link name";
QString sLinkArguments = "link arguments";
QString sLinkIcon = [MY_EXE_PATH]; // Here: can I use the pixmap I have in runtime?
 
WCHAR pathDesktop[MAX_PATH];
HRESULT result = SHGetFolderPathW(NULL, CSIDL_DESKTOPDIRECTORY, NULL, 0, pathDesktop);
 
if (SUCCEEDED(result)) {
    QString linkPath = QDir(QString::fromWCharArray(pathDesktop)).absoluteFilePath(QString("%1.lnk").arg(sLinkName));
 
    CoInitialize(NULL);
    IShellLinkW* shellLink = NULL;
    result = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_ALL, IID_IShellLinkW, (void**)&shellLink);
    if (SUCCEEDED(result)) {
        shellLink->SetPath(sPathTarget.toStdWString().c_str());
        shellLink->SetArguments(sLinkArguments.toStdWString().c_str());
        shellLink->SetIconLocation(sLinkIcon.toStdWString().c_str(), 0);
        IPersistFile* persistFile;
        result = shellLink->QueryInterface(IID_IPersistFile, (void**)&persistFile);
 
        if (SUCCEEDED(result)) {
            result = persistFile->Save(linkPath.toStdWString().c_str(), TRUE);
 
            persistFile->Release();
 
            bRet = true;
        }
        shellLink->Release();
    }
}

Thanks,
