I get the feeling i'm missing some silly little thing, but i can't find it. Here is some of the code: I have a class that extends WNDCLASSEX like this, so that it has a normal std::string for a class name and a simplified constructor: #ifndef WINDOWCLASS_H #define WINDOWCLASS_H #include #include #include "WindowAbstract.h" using namespace std; class WindowClass : public WNDCLASSEX { public: WindowClass(string className, WindowAbstract * window); ~WindowClass(); bool Register(); string ClassName() {return m_className;} friend class WindowAbstract; private: string m_className; }; #endif And here is the constructor for the class: WindowClass::WindowClass(string className, WindowAbstract * window) { cbSize = sizeof(WNDCLASSEX); style = 0; lpfnWndProc = window->WndProc; cbClsExtra = 0; cbWndExtra = 0; hInstance = hInstance; hIcon = LoadIcon(NULL, IDI_APPLICATION); hCursor = LoadCursor(NULL, IDC_ARROW); hbrBackground = (HBRUSH)(COLOR_WINDOW+1); lpszMenuName = NULL; lpszClassName = className.c_str(); hIconSm = LoadIcon(NULL, IDI_APPLICATION); m_className = className; } here is the register function to be called after it's constructed: bool WindowClass::Register() { if(RegisterClassEx(this) == 0) return false; return true; } The WindowAbstract class contains the window procedure and is created first, to pass the pointer to it's function to the WindowClass object. #ifndef WINDOWABSTRACT_H #define WINDOWABSTRACT_H #include #include using namespace std; class WindowAbstract { public: WindowAbstract(); ~WindowAbstract(); bool Create(string windowTitle, strin

The inhabitants call it Earth Posts 6,330 [RESOLVED] 1407 Cannot Find Window Class when I call CreateWindowEx I've been writing a rich ediot text userControl to handle unicode and, wonder of wonders, I've got it doing most of what I want error 1407 cannot . I have one outstanding problem though, sometimes it just fails to load and I get a blank grey box on my form. Tracing through the code the oproblem seems to be when I create the window for the rich edit:- create window Code: m_WndRE = CreateWindowEX(ExStyle, "RichEdit20A", vbNullString, Style, 0, 0, UserControl.Width, UserControl.Height, UserControl.hwnd, 0&, App.hInstance, ByVal 0&) If m_WndRE = 0 Then MsgBox Err.LastDllError() End If That message box is showing 1407 which equates to Can't Find Window Class. It's really wierd, once it happens it keeps happening no matter what I do. Then, apparently at random, it starts working again. I'll do some further development and then, apparently at random, it stops working again. There doesn't seem to be any pattern to it. Any idea what might cause this? I really want to get to the bottom of it before I release this on an unsuspecting world. edit>Possibly the best typo I've ever made: "I've been writing a rich ediot text userControl" When one of my minions says, "Hey, he's just one guy, what can he do?"

This argument contains the DLGTEMPLATE-structure immediately followed by a menu array, a class array and a title array. This main template is followed bij "n" DLGITEMTEMPLATEs, in which "n" is defined in the DLGTEMPLATE.Each DLGITEMTEMPLATE is followed by 3 arrays containing class, title and creation date elements.Be sure each array starts at a WORD (=integer*2) boundary.I will advise you to carefully follow the rules in the documentation of the templates, because is it a hell of a job to get it working.
