    Tab Control Win32 API

    Hi, could someone tell me how to fix this? The edit control does not show up however the mouse changes around the position i want it to display.

    https://netfiles.uiuc.e du/qmitche2/www/tabs.exe

    Code:
    #include <windows.h>
#include <commctrl.h>
#include <stdio.h>

HWND hwndMain;
HWND hwndTab;
HWND hwnd0;
HWND hwnd1;
HWND hwnd2;
HWND hwnd3;
HINSTANCE hinst;

LRESULT CALLBACK ChildrenProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch(msg)
    {
        case WM_CLOSE:
            DestroyWindow(hwnd);
        break;
        
        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}


void CloseWindows()
{
	DestroyWindow( hwnd0 );
	DestroyWindow( hwnd1 );
	DestroyWindow( hwnd2 );
	DestroyWindow( hwnd3 );
}

void MakeWindow(int num)
{
	if(num==0)
	{
		hwnd0=CreateWindowEx(0, 
				"TabChild", 
				"", 
				WS_CHILD|WS_VISIBLE|WS_CLIPSIBLINGS, 
				0, 0, 
				300, 300, 
				hwndMain, 
				NULL,

					WS_VISIBLE | WS_CHILD | WS_TABSTOP | WS_BORDER,
					0, 50, 100, 25,

          Sorry for reviving an old thread but heres a way better/cooler solution with more functionality
          Code:
          #include <windows.h>
#include <commctrl.h>
#include <stdio.h>

HWND hwndMain;
