推荐答案

好像对DialogBox的调用对我来说很麻烦.我还没有听说过一个名为"AboutBox"的DialogTemplate.这是您在其他地方实现的吗?

我更习惯使用resource_id来调用它，以将对话框从exe的资源部分中拉出.

即
DialogBox(hInstance，MAKEINTRESOURCE(IDD_ABOUT_BOX)，hwnd，lpDlgProc);

其中IDD_ABOUT_BOX是在某处#define定义的，并用作资源编辑器中对话框的资源标识符.

Looks like the call to DialogBox is screwy to me. I''ve not heard of a DialogTemplate called "AboutBox". Is this something you have implemented elsewhere?

I''m more used to calling this using a resource_id to pull a dialog box out of the exe''s resource section.

I.e
DialogBox(hInstance, MAKEINTRESOURCE(IDD_ABOUT_BOX), hwnd, lpDlgProc);

Where IDD_ABOUT_BOX is #defined somewhere and is used as the resource identifier for the dialog in the resource editor.

DialogBox(hInstance，TEXT("AboutBox")，hwnd，IpDlgProc)

第三个参数应为MAKEINTRESOURCE(IDD_DIALOG1)
其中IDD_DIALOG1是dilogbox的ID

对话框(hInstance，MAKEINTRESOURCE(IDD_DIALOG1)，hwnd，IpDlgProc)

DialogBox (hInstance, TEXT ("AboutBox"), hwnd, IpDlgProc)

3rd parameter should be MAKEINTRESOURCE(IDD_DIALOG1)
where IDD_DIALOG1 is the id of dilogbox

DialogBox (hInstance, MAKEINTRESOURCE(IDD_DIALOG1), hwnd, IpDlgProc)
