Overlapped Text and Window

I want to make a simple addition calculator for my own learning, and im trying to paint the '+' sign in, but my border window is overlapping it. Obviously if I take out the border window, it shows up, but I would like to keep it there....looks cool ;)

Heres my code:

Code:

---

#include <windows.h>

static char gszClassName[]  = "MyWindowClass";
static HINSTANCE ghInstance = NULL;

HWND hBorder,hBox1,hBox2,hEqual,hBox3;

LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    HDC hdc;
    PAINTSTRUCT ps;
    LPSTR szMessage = "text_test";

    switch(Message)
    {
          case WM_PAINT:
          {
                  hdc = BeginPaint(hwnd, &ps);
                  TextOut(hdc, 70, 40, szMessage, strlen(szMessage));
                  EndPaint(hwnd, &ps);
          }
          break;

          case WM_CREATE:                                                                                                                                   
          {                   
                  hBorder = CreateWindowEx
                                (
                                    NULL,
                                    "Static",
                                    "",
                                    WS_CHILD | WS_VISIBLE | WS_BORDER,
                                    4, 2,
                                    196, 46,
                                    hwnd, NULL,
                                    ghInstance,
                                    NULL
                                );       

                  hBox1  = CreateWindowEx
                                (
                                    WS_EX_RIGHT | WS_EX_CLIENTEDGE,
                                    "Edit",
                                    "",
                                    WS_CHILD | WS_VISIBLE,
                                    10, 14,
                                    30, 20,
                                    hwnd, NULL,
                                    ghInstance,
                                    NULL
                                );
          }
          break;
               
          case WM_CLOSE:
                  DestroyWindow(hwnd);
          break;

          case WM_DESTROY:
                  PostQuitMessage(0);
          break;

          default:
                  return DefWindowProc(hwnd, Message, wParam, lParam);
    }
   
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    WNDCLASSEX WndC;
    HWND hwnd;
    MSG Msg;

    ghInstance = hInstance;

    WndC.cbSize        = sizeof(WNDCLASSEX);
    WndC.style        = NULL;
    WndC.lpfnWndProc  = WndProc;
    WndC.cbClsExtra    = 0;
    WndC.cbWndExtra    = 0;
    WndC.hInstance    = ghInstance;
    WndC.hIcon        = LoadIcon(NULL, IDI_APPLICATION);
    WndC.hCursor      = LoadCursor(NULL, IDC_ARROW);
    WndC.hbrBackground = (HBRUSH)(COLOR_WINDOW+0);
    WndC.lpszMenuName  = NULL;
    WndC.lpszClassName = gszClassName;
    WndC.hIconSm      = LoadIcon(NULL, IDI_APPLICATION);

    if(!RegisterClassEx(&WndC))
    {
          MessageBox(0, "Window Registration Failed!", "Error!", MB_ICONSTOP | MB_OK);
          return 0;
    }

    hwnd = CreateWindowEx
          (
                  WS_EX_STATICEDGE,
                  gszClassName,
                  "math_test",
                  WS_SYSMENU | WS_MINIMIZEBOX,        //WS_OVERLAPPEDWINDOW
                  CW_USEDEFAULT, CW_USEDEFAULT,
                  210, 75,
                  NULL, NULL,
                  ghInstance,
                  NULL
          );

    if(hwnd == NULL)
    {
          MessageBox(0, "Window Creation Failed!", "Error!", MB_ICONSTOP | MB_OK);
          return 0;
    }

    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    while(GetMessage(&Msg, NULL, 0, 0))
    {
          TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }
   
    return Msg.wParam;
}

So why not make the edit bigger?

I want the text to be on top of hBorder.

Code:

---

          case WM_PAINT:
          {
                  hdc = BeginPaint(hwnd, &ps);
                  TextOut(hdc, 70, 40, szMessage, strlen(szMessage));
                  EndPaint(hwnd, &ps);
          }
          break;

Is there way to get that to paint before i create hBorder?

...try this after you create the static window:

Code:

---


HDC dc = GetDC(hBorder);
int mode = GetBkMode(dc);
mode = (mode == 1) ? 2 : 1;
SetBkMode(dc, mode);
ReleaseDC(hBorder, dc);

---

Actually, use this first:

Code:

---


HDC dc = GetDC(hBorder);
if(GetROP2(dc) != R2_COPYPEN) {
  SetROP2(dc, R2_COPYPEN);
 }
ReleaseDC(hBorder, dc);

---

None of those worked, but I found another way:

Code:

---

hPlus  = CreateWindowEx
      (
        NULL,
        TEXT("Static"),
        TEXT("+"),
        WS_CHILD | WS_VISIBLE | SS_SIMPLE,
        45, 12,
        30, 25,
        hwnd, NULL,
        ghInstance,
        NULL
      );

---

Another thing....how would you extract data from a text box?

For example if someone typed in 5 into a text box, how could i extract out the data so it could be used as a variable to be added to another number in another text box.

Thanks!

GetWindowText returns zero if there is no text in the control....

Code:

---


int buffmax = 100;
char * buffer = new char[buffmax];
//...
if( GetWindowText(hwnd, buffer, buffmax) ) {
  int val = atoi(buffer);
 }
