[QUOTE="dmxlight, post: 857007, member: 121196"] Hello, Many years ago I wrote in Pascal, more recently I have been learning C++ using Visual Studio 2010. I have a stand alone video recorder app I wrote in C++ to copy my old video tapes onto mpeg. I am planning to integrate this app into a MP plugin. I have created a dll in C# from the tutorial on the MP wiki, this works ok, it reads the author and captures button presses. I have converted that C# code to C++ and compiled a new dll, MP see's the dll, it reads the author and plugin name ok, but the problem is that the dll will not capture the button presses from MP. I am sure I have made a simple mistake but I cannot figure it out. I looked on the forum for C++ example code but could not find any, so when I am finished I will submit mu code as an example for others wanting to use C++ for dll's. The code I have for capturing the buttons onclick events is shown below. I have only pasted just the button related code to keep the post short, I am sure I have just missed a ^ or : somewhere. C++ .h file public ref class Class1 : GUIWindow, ISetupForm { public: [SkinControlAttribute(2)] GUIButtonControl ^buttonOne; public: virtual void OnClicked(int controlId, GUIControl ^control, MediaPortal::GUI::Library::Action::ActionType ^actionType) override; private: void OnButtonOne(); C++ .cpp file void Class1::OnClicked(int controlId, GUIControl ^control, MediaPortal::GUI::Library::Action::ActionType ^actionType) { if (control == buttonOne) OnButtonOne(); GUIWindow::OnClicked(controlId, control, *actionType); } void Class1::OnButtonOne() { MessageBox::Show("button one clicked"); GUIDialogOK ^dlg = safe_cast<GUIDialogOK^>(GUIWindowManager::GetWindow(safe_cast<int>(GUIWindow::Window::WINDOW_DIALOG_OK))); dlg->SetHeading("Button has been pressed"); dlg->SetLine(1, "You pressed button 1"); dlg->SetLine(2, String::Empty); dlg->SetLine(3, String::Empty); dlg->DoModal(GUIWindowManager::ActiveWindow); } Many thanks, Mike [/QUOTE]
