You need to set the cursor position manually. If you are using MFC use CCoboBox::SetEditSel()[^] API, otherwise send the control the CB_SETEDITSEL[^] message. Set start and end char to be the length of your string.

Resize the ListBox using MoveWindow API while changing from full screen to regular mode and vice versa.

Adding to the Niklas Lindquist suggestions in the below post
GetClientRect API helps to obtain the client area of the Window. Get the parent window's client area and resize listbox according to it or the way you want.

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.

aangerma28-Jun-10 2:08

28-Jun-10 2:08

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)

For some reason I read the mis-spelling as FillScreaM, and I thought the OP wanted something to get immediate attention!

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.
