);定做个对话框程序.
现在倒是在WM_CREATE中PostMessage一个自定义消息解决了,但还是想弄懂这个问题。
EN_CHANGE,EM_UPDATE这些对应的消息.
这个不是dialog的对话框过程?!
LRESULT CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
原型都一个样子的啊
不妨HOOK下CreateWindowEx()就知道了。
INT_PTR CALLBACK DialogProc(HWND hwndDlg,UINT uMsg,WPARAM wParam,LPARAM lParam);
它们的返回值不同的,下面这段解释得更清楚:
Typically, the dialog box procedure should return TRUE if it processed the message, and FALSE if it did not. If the dialog box procedure returns FALSE, the dialog manager performs the default dialog operation in response to the message.
