All you have to do is SetWindowPos[^] and use some kind of accelerator key combination to switch back and forth.

You might have to handle WM_MINMAXINFO[^] to allow the control to be larger than the actual screen if you want to hide borders. Alternatively, you could modify the window style to achieve the same.

The GetSystemMetrics[^] API will give you the size of the screen using the SM_CXFULLSCREEN and SM_CYFULLSCREEN parameters.

Disclaimer: there might be another way get the screen size to support multiple monitor systems.

thank you,
I tried it but I can't get the handle to the window i.e. the first parameter of GetSystemMetrics is CWnd* and I don't know how to get it.
can you please help me with this?

GetSystemMetrics has only one parameter which is an int.
GetSystemMetrics(SM_CXFULLSCREEN) and GetSystemMetrics(SM_CYFULLSCREEN) should work.

Which version of the API accepts a CWnd*?

sorry I had a mistake I ment that SetWindowPos accepts a CWnd* as parameter.

Use NULL (or nullptr) and add the flag SWP_NOZORDER at the end.

I insert this on the constructor of the dialog:

int x=GetSystemMetrics(SM_CXFULLSCREEN);
int y=GetSystemMetrics(SM_CYFULLSCREEN);
SetWindowPos(NULL,0,0,x,y,SWP_NOZORDER );

and its give me Debug Assertion Failed.

do you know what can be the resone?

thanks again

In your constructor the underlying window has not yet been created, and that's why the call fails. Put it in your OnInitDialog handler instead.

Dislplaying bitmap image on the screen when raw bitmap data is available in memory? (WIN32)

27-Jun-10 21:26

Including the bmp image as resource isn't secure (as anyone can tamper easily).

So, I form the raw bitmap data (excluding headers) at runtime using some obfuscated code. The image is 208 pixels wide and has a height of 97 pixels. It takes 24bits per pixel. I'm very weak in GDI. I got a code to display image from resource and I tried modifying. Unfortunately, it didn't work Frown | :(

I'm MFC free till now and would like to remain so Big Grin | :-D

Plz let me know the right approach.

Here is what I tried:

/* ************* Some Globals:********************* */
	HBITMAP bmpExercising;
	BITMAP bitmap;

/* ************* After Calls to CreateWindow ********************* */
	bmpExercising = CreateCompatibleBitmap(GetDC(myWind), 208, 97);
	GetObject(bmpExercising, sizeof(bitmap), &bitmap);

	bitmap.bmBits = buf;
	bitmap.bmBitsPixel = 24;
	bitmap.bmHeight = 97;
	bitmap.bmWidth = 208;
	bitmap.bmPlanes = 1;

/* Declared variables in WindProc */
HDC hDC, MemDCExercising;
PAINTSTRUCT Ps;

/* ************* in WM_PAINT: ********************* */
case WM_PAINT:
	hDC = BeginPaint(hwnd, &Ps);
	MemDCExercising = CreateCompatibleDC(hDC);
	SelectObject(MemDCExercising, bmpExercising);
	BitBlt(hDC, 10, 10, 208, 97, MemDCExercising, 0, 0, SRCCOPY);
	DeleteDC(MemDCExercising);
	DeleteObject(bmpExercising);
	EndPaint(hwnd, &Ps);
	break;

I want to do it without MFC

I'm using Visual C++ 2005 Professional. Windows XP Professional with SP3.

There are a number of errors, I will list a few.

Selecting a GDI object into your device context needs to be followed by the same object being selected out of the dc. In your case

HGDIOBJ oldbmp = ::SelectObject(dc, bmp);
// Do some blitting
::SelectObject(dc, oldbmp);
DeleteDC(dc);

Your paint code will only have a bitmap the first time it paints, since you delete the bitmap there. Delete your bitmap in WM_DESTROY handler instead.

Also:
Your blitting area is 10x10 less than your bitmap.

look in the source of that great article.
CBitmapEx - Free C++ Bitmap Manipulation Class[^]

You can debug in the MFC code to view some details.

/* ************* After Calls to CreateWindow ********************* */
bmpExercising = CreateCompatibleBitmap(GetDC(myWind), 208, 97);
GetObject(bmpExercising, sizeof(bitmap), &bitmap);

//you cant modify this data in that way.
/*bitmap.bmBits = buf;
bitmap.bmBitsPixel = 24;
bitmap.bmHeight = 97;
bitmap.bmWidth = 208;
bitmap.bmPlanes = 1;*/

//use ::SetPixel() - API for every pixel one time

Press F1 for help or google it.

Round Button

Hi,

I am creating a ownder draw button with Round Edges. I tried the bolw code for round edged in OnDraw()

//make round corner
CRgn rgn;
CRect crt;
GetClientRect(&crt);
rgn.CreateRoundRectRgn( crt.left, crt.top, crt.right, crt.bottom, 13, 13);
SetWindowRgn(rgn,1);

Button is coming with round edges but If button repaints it is becoming rectanglular shape button.
What shall I do?

I think your drawing the whole rectangular area of the button in OnDraw function.

Draw only the round rectangular area of the button.
OR
Draw the button with the dialog background first and then draw the remaining things.

Which buffer are you talking about? Give us a hint.

This looks messed up:

InitialMenu* initMenu = new InitialMenu();
initMenu->Run();
initMenu->~InitialMenu();

Normally, you should not call the destructor as a function. Use delete initMenu; instead, and the destructor will be called for you (and the memory you allocated will be freed.)

But I suggest

InitialMenu initMenu;
initMenu.Run();

Why are you using ::driver in some places and driver in others? I'd also be suspicious of having to array delete loads of things that are used just like single objects. I'd be doubly suspicious of having to delete objects that I didn't allocate with new but that might be just poor design on the part of the library.

That library looks pretty ghastly as well - are you sure there aren't some higher level interfaces in there somewhere you're not using? It looks really fiddly and low level to me.

All code in it, mainly includes, is put in a precompiled header file (*.pch) once. If you compile two translation units (.cpp files) using precompiled headers, only the first will go through all the code in stdafx.h. The second will use the precompiled data found in the .pch file instead.

The main reason for this is compilation speed.

Normally you put stuff in stdafx.h that changes rarely, because if you modify it, it will trigger a full rebuild on the next compilation.
