How to output a string of characters on top of the wallpaper

I'm using a VC++ 6 application that can display bitmap files as wallpapers. Now I want to output a string of letters on top of that bitmap, i.e., different strings for different bitmaps. Please any expert can give any suggestion?
Btw that string can be assigned different fonts and/or color and must have a transparrent background as not to affect the bitmap itself.

when u say wallpaper, you are refering to the application wallpaper right?

one way to do it is using GDI calls to draw the string after you have drawn the bitmap

i'm currently posting outside and has no access to my MSDN and can't post examples...if u wish, i could do that when i reach hom

you can get a handle to the desktop window using GetWindowDC() and then you can call TextOut()


HDC dc = GetWindowDC(GetDesktopWindow());

TextOut(hdc, 0, 0, "Jason", 6);

BUT..... this text will dispear when the desktopwindow repaints itself so you need to know when the desktop will repaint itself andthen recall the above code.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You could add bitmap button to your main form, make it as big as the form and assign the wallpaper as bitmap. The button needs to be first in tab order. Any other control can be made transparent by property thus appearing properly above the wallpaper.

If you need jpeg or png you might turn the *button* to an owner-draw button Then you need to supply a callback function DrawItem which does all drawing itself. You could move all code that paints the wallpaper now to the DrawItem function. Moreover, the function is suitable to do any additional drawing, e. g. drawing coloured text to anywhere using the current device context (GDI).

Thanx for al your help. However I still could not make it to work. Now let's forget about wallpapers for now and get back to a simple question:
How do I output a line of text on any deskop?
I have a hard time writing some routine, so a real example will be very helpful.

You can do one of 2 things:

1. Get the DC of the desktop. You can then draw on that.
CClientDC dcDesktop(CWnd::GetDesktopWindow());
dcDesktop.TextOut(...);

OR

2. Get the DC of the display device.
CDC dc;
dc.CreateDC("DISPLAY", NULL, NULL, NULL);
dcDesktop.TextOut(...);
dc.DeleteDC();
