CreateDialog() without using Resource.h and '.rc' file..?

Trying to create a Modeless Dialog Box in WinAPI but without using a predefined Resource file.

How would I go about doing that with CreateDialog()?

Documentation states for the second parameter:

Quote:

---

lpName
Type: LPCTSTR
The dialog box template. This parameter is either the pointer to a null-terminated character string that specifies the name of the dialog box template or an integer value that specifies the resource identifier of the dialog box template.

---

Could someone provide an example that uses a "null-terminated character string"?

How do I define the characteristics of the Dialog Box if I'm not using a Resource.h or .rc template?

Have tried researching examples online but they all seem to use Resource files.

Also, how do I determine the correct value to place in the first parameter (HINSTANCE)?

Oh... I found THIS:

Let me know if there's anything else to add... :wave:

The dialog box doesn't appear.

Main window becomes inactive when I call CreateWindow() but no Dialog Box appears.

Have a look at CreateDialogIndirectParam() https://docs.microsoft.com/en-us/win...indirectparama

This lets you specify the contents of a dialog using structures in your program rather than a resource file.

Oh I found the error...

I was forgetting to call DefWindowProc(hWnd, msg, WP, LP); in my AboutProc message handler:

Code:

---


LRESULT CALLBACK AboutProc(HWND hWnd, MSG msg, WPARAM WP, LPARAM LP)
{

default:
DefWindowProc(hWnd, msg, WP, LP);

}

---

Without that line of code the call to CreateWindow() is not processed until completion so the Dialog Box never displays.

It's an elementary error but one worth noting as a possible cause of this behaviour.

Appreciate your help..!

Glad you solved your problem! :thumb:
However, two questions:
1. is it so important for you to not use MFC, but only the plain Win32 API?
2. What prevents you to use resource template (.rc) file?
