Not MSDN FORUM: Modern Windows GUI / API tutorial

Question

I have been following this tutorial however certain data types do not work.. such as identifier is not defined or wrong parameters.. ?? I am using Visual Studio Community 2019 - Win32 Application project .. not a .net forum!!
https://www.youtube.com/watch?v=9JMQkUOhW1s
For instance, CreateWindowW tries to become CreateWindowExW and so I looked into the documentation of how to use it but the windows studio is not satisfied. Even the hMenu = CreateMenu(); states that hMenu is not defined.. or does not have a datatype. so I tried to do HMENU hMenu = Createmenu();// please help guys I will further eleaborate my questions as needed
Or could you guys help provide an example of how to call this ??

FORMAT:

CreateWindowExW(
In DWORD dwExStyle,
_In_opt_ LPCWSTR lpClassName,
_In_opt_ LPCWSTR lpWindowName,
In DWORD dwStyle,
In int X,
In int Y,
In int nWidth,
In int nHeight,
_In_opt_ HWND hWndParent,
_In_opt_ HMENU hMenu,
_In_opt_ HINSTANCE hInstance,
_In_opt_ LPVOID lpParam);

Answer 1

#define CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y,\  
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\  
CreateWindowExW(0L, lpClassName, lpWindowName, dwStyle, x, y,\  
nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)  

As the previous snippet shows, CreateWindowW(...) expands to CreateWindowExW(0, ...). It is recommended to use CreateWindow or CreateWindowEx.
And the following picture shows the corrected program has a global variable HMENU hMenu.

Answer 2

The first parameter for your CreateWindowW is 0L; remove that.

I am not sure what you did with hMenu and such; undo what you did and restore it back to what is in the YouTube.

I am not going to watch the entire YouTube.

I suggest you use Visual Studio to generate a sample application. You can build it immediately after creating the project and see how Microsoft does it. I am using VS 2017 but I assume the procedure for VS 2019 is the same or close enough. In the C++ templates find the Windows Desktop Wizard. Select it and then select a Desktop Application. See Windows Desktop Wizard; create a Windows Application using the defaults. Also see Walkthrough: Create a traditional Windows Desktop application (C++); that begins with a blank project and builds from there; I assume the result is the same as if you created the Windows Application that is not blank.

Answer 3

Nevermind guys I got it working now thank you :) !!
