Hi,

I'm pretty desperate here. I have created a halfway decent program that is short but useful. It loads a text file and displays the file contents line-by-line to a window. The problem is that my mouse icon, when in the window, after the window is displayed, displays a hollow circle that keeps spinning, as if the program is not finished performing a task yet. And when I hover over the edges of the window, so that I can resize them, and then move the mouse into the white area of the window where you should not have the horizontal or vertical resize mouse icons, they still appear there. I'm very sorry for posting this long code, but I really am getting into windows programming. I'm tired of not knowing the proper way to do things,

Did you try setting the hCursor member of your WNDCLASS?

Did you try setting the hCursor member of your WNDCLASS?

SiCrane you are a god in my eyes. I don't know if that's the problem, but you are an extremely helpful member on these forums!

Thank you so, so, much.

In truth, I just initialized the window class the short and sloppy way because I was being lazy and was following the guide on MSDN.

From MSDN:

hCursor Type: HCURSOR

A handle to the class cursor. This member must be a handle to a cursor resource. If this member is NULL, an application must explicitly set the cursor shape whenever the mouse moves into the application's window.

There's no end to learning, I tell you. I'll be a beginner forever :0)
