Help with RichEdit Window

[The_Goat()]

I am creating a program in C that should allow a richedit window to be created and shown.

To do this, I have a function.

HWND richedit_creater(double h,double w,HWND hwnd,PCHAR text)
{
         HANDLE r_lib = LoadLibrary("RICHED32.DLL");
        
        HWND r_hwnd = CreateWindowEx(WS_CHILD,RICHEDIT_CLASS,
        text,1,0,0,(int)h,(int)w,hwnd,(HMENU)0,
      (HINSTANCE)GetWindowLong(hwnd,GWL_HINSTANCE),
        NULL);
      return r_hwnd;
       
}

It compiles fine, and I get no errors. But when I run it, even when simply calling it from a console-app main(), it runs but the window does not does not ever appear. I have tried ShowWindow, GetLastError returns 0...
I'm a bit confused.

Could anyone help?
Thanks,

        NULL);
      return r_hwnd;
       
}

Several errors. Mainly you should look up CreateWindowEx.

First argument to CreateWindowEx is dwExStyle, Extended Style. WS_CHILD isn't valid. Valid styles start with WS_EX_.
Fourth argument is dwStyle. You passed 1. (What is 1?) That should be an OR'd value of styles: things that start with WS_. You'll probably want to pass WS_CHILD and WS_VISIBLE, along with any RICHEDIT specific ones.
Arguments 7 & 8 are ints. You're casting a double to an int - bad. Don't cast, and it should convert them properly for you. But why are you using doubles? Width and height cannot have a decimal... they describe pixels.

Otherwise, do you get a valid handle back? CreateWindowEx will return NULL on failure.
