Creating Windows Will Be Easier...

I recently prepared a window creating header file for Win32 programming. I want to share it with you guys.
Code:
class CCommon
{
public:
DWORD dwExStyle;
char lpClassName[MAX_LOADSTRING];
char lpWindowName[MAX_LOADSTRING];
DWORD dwStyle;
int x;
int y;
int nWidth;
int nHeight;
HWND hWndParent;
HMENU hMenu;
HINSTANCE hProgInst;
LPVOID lpParam;
HWND hWnd;
HANDLE hImage;
CHAR szImageFile[MAX_LOADSTRING];
CCommon()
{
dwExStyle = 0;
StringCbCopy(lpClassName , MAX_LOADSTRING, "ClassName");
StringCbCopy(lpWindowName , MAX_LOADSTRING, "Caption");
dwStyle = WS_VISIBLE | WS_CHILD;
x = 5;
y = 5;
nWidth = 100;
nHeight = 100;
hWndParent = HWND_DESKTOP;
hMenu = NULL;
lpParam = NULL;
}
VOID SetInitials(INT x, INT y, INT nWidth, INT nHeight)
{
this->x = x;
this->y = y;
this->nWidth = nWidth;
this->nHeight = nHeight;
}
void Create(void)
{
hWnd = CreateWindowEx( (DWORD) dwExStyle,
(LPCTSTR) lpClassName,
(LPCTSTR) lpWindowName,
(DWORD) dwStyle,
(int) x,
(int) y,
(int) nWidth,
(int) nHeight,
(HWND) hWndParent,
(HMENU) hMenu,
(HINSTANCE) hProgInst,
(LPVOID) lpParam);
DWORD ErrCode = GetLastError();
if (hWnd == NULL)
{
MessageBox(NULL, "Error creating control.", "Error", MB_OK);
DebugTest(ErrCode);
}
}
void Enable(bool State)
{
EnableWindow(hWnd, State);
}
char * GetText(unsigned long int MaxChars)
{
char * Buffer = new char[MaxChars];
SendMessage(hWnd, WM_GETTEXT, (WPARAM) MaxChars, (LPARAM) Buffer);
return Buffer;
delete Buffer;
}
void SetText(char * Buffer)
{
if(!SendMessage(hWnd, WM_SETTEXT, (WPARAM) NULL, (LPARAM) Buffer))
{
DWORD dwError = GetLastError();
DebugTest("Error setting text"); DebugTest(dwError);
}
}
void SetImage(void)
{
hImage = LoadImage(hInstance, szImageFile, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
SendMessage(hWnd, STM_SETIMAGE, (WPARAM) IMAGE_BITMAP, (LPARAM) hImage);
}
};
class CUserDefined : public CCommon
{
public:
WNDCLASSEX WindowClass;
CUserDefined()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "ClassName");
WindowClass.cbSize = (UINT) sizeof(WNDCLASSEX); //Defaults for WNDCLASSEX
WindowClass.style = (UINT) CS_DBLCLKS;
//WindowClass.lpfnWndProc = (WNDPROC) WindowProcedure;
WindowClass.cbClsExtra = (INT) 0;
WindowClass.cbWndExtra = (INT) 0;
//WindowClass.hInstance = (HINSTANCE) hProgInst;
WindowClass.hIcon = (HICON) LoadIcon (NULL, IDI_APPLICATION);
WindowClass.hCursor = (HCURSOR) LoadCursor (NULL, IDC_ARROW);
WindowClass.hbrBackground = (HBRUSH) COLOR_BACKGROUND;
WindowClass.lpszMenuName = (LPCTSTR) NULL;
WindowClass.lpszClassName = (LPCTSTR) lpClassName;
WindowClass.hIconSm = (HICON) LoadIcon (NULL, IDI_APPLICATION);
}
void RegisterAndCreate(void)
{
if (!RegisterClassEx(&WindowClass)) MessageBox(NULL, "Error registering.", "Error", MB_OK);
Create();
}
void Enable(bool State)
{
EnableWindow(hWnd, State);
}
};
class CEdit : public CCommon
{
public:
CEdit()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "EDIT");
}
};
class CStatic : public CCommon
{
public:
CStatic()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "STATIC");
}
};
class CImage : public CCommon
{
public:
//HANDLE hImage;
//CHAR szImageFile[MAX_LOADSTRING];
CImage()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "STATIC");
dwStyle |= SS_BITMAP;
}
//VOID SetImage(CHAR * szFileName)
//{
// hImage = LoadImage(hInstance, szFileName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
// SendMessage(this->hWnd, STM_SETIMAGE, (WPARAM) IMAGE_BITMAP, (LPARAM) hImage);
//}
//VOID SetImage(VOID)
//{
// hImage = LoadImage(hInstance, szImageFile, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
// SendMessage(hWnd, STM_SETIMAGE, (WPARAM) IMAGE_BITMAP, (LPARAM) hImage);
//}
};
class CButton : public CCommon
{
public:
CButton()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "BUTTON");
}
};
class CFrame : public CCommon
{
public:
CFrame()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "BUTTON");
dwStyle |= BS_GROUPBOX;
}
};
class CCheckBox : public CCommon
{
public:
CCheckBox()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "BUTTON");
}
};
class CRadioButton : public CCommon
{
public:
CRadioButton()
{
StringCbCopy(lpClassName , MAX_LOADSTRING, "BUTTON");
dwStyle |= BS_AUTORADIOBUTTON;
}
};
class CMessageLoop
{
public:
MSG Message;
HWND hWnd;
UINT wMsgFilterMin;
UINT wMsgFilterMax;
BOOL bReturnValue;
BOOL bContinue;
DWORD dwLastError;
CMessageLoop()
{
hWnd = NULL;
bContinue = TRUE;
wMsgFilterMin = 0;
wMsgFilterMax = 0;
dwLastError = 0;
}
VOID Loop(VOID)
{
do
{
switch(bReturnValue = GetMessage(&Message, NULL, wMsgFilterMin, wMsgFilterMax))
{
case 0:
bContinue = FALSE;
break;
case -1:
dwLastError = GetLastError(); //For future use
if(IDNO == MessageBox(NULL, "Error occured in the message loop.\nDo you want to continue?", "Message Loop", MB_YESNO | MB_ICONERROR))
bContinue = FALSE;
break;
default:
TranslateMessage(&Message);
DispatchMessage(&Message);
}
} while (bContinue);
}
};
Here is an example :
Code:
CUserDefined MainWnd;
MainWnd.SetInitials(100, 100, 800, 480);
MainWnd.hProgInst = hInstance;
MainWnd.WindowClass.hInstance = hInstance;
StringCbCopy(MainWnd.lpWindowName, MAX_LOADSTRING, "Window Title");
MainWnd.WindowClass.lpfnWndProc = (WNDPROC) WindowProcedure;MainWnd.RegisterAndCreate();
To create a button on this window :
Code:
CButton Button;
Button.SetInitials(100, 100, 800, 480);
Button.hWnd = MainWnd.hWnd;
Button.Create();
I am still improving this header. There may be bugs and errors. If you ever happen to come across any problem, or have any suggestions please write under this topic.
Note : You don't have to copy/paste. I attached a zip file, just download it. |
