how do i make this a different color..

hey, i have a "login" window for this program i'm writing. the login is locally, not very secure, etc. but i dont need it to be fort knox as this is my first time playing around with such methods. however, my question is about something that irritates me to no end...on my login window, theres the window, menu, edit box, and button. you can see it here:

the background of the login window is white. i would like to paint it a different color. i know how to create a brush..but i dont know how to modify the color of that area. right now for HWND's that i have declared, theres one for the main window, one for the login button, one for the edit box, and one for the status bar.

so..how do i do it? :) thanks.

In your paint handler you could create a brush and use FillRect(), Rectangle() or similar on the RECT in the PAINTSTRUCT or on the client area.

Try CreatePatternBrush() using an image......

Or (simplified) load an image, CreateCompatibleDC(), CreateCompatibleBitmap() and BitBlt() the image to the PAINTSTRUCT hdc.

Some pseudo code of what your WM_PAINT event handler would look like:

Code:

---

HDC hdc, hdcMem;
HBITMAP hbmMem;
HANDLE hOld;
hdc = BeginPaint(hwnd,&ps);
/* Create an off-screen DC for double-buffering */
hdcMem = CreateCompatibleDC(hdc);
hbmMem = CreateCompatibleBitmap(hdc, width, height);
hOld  = SelectObject(hdcMem, hbmMem);
FillRect(hdcMem,&rClient,(HBRUSH)COLOR_WINDOW);
/* Transfer the off-screen DC to the screen */
BitBlt(hdc, 0, 0, width, height, hdcMem, 0, 0, SRCCOPY);
/* Free-up the off-screen DC */
SelectObject(hdcMem, hOld);
DeleteObject(hbmMem);
DeleteDC(hdcMem);
EndPaint(hwnd,&ps);

Change the FillRect() HBRUSH value to the color you want. You can use CreateSolidBrush() to create a brush with the color value you want.

thanks guys :)
the pseudo code was a big help in making it work. this is what it looks like now:

Something else you could always do is set the windows background color in it's class before creating it.

mm...huh? / how?

the program is a text editor..and i dont want the edit box to be non-white after the user logs in, i just want the window non-white for the login screen. that still work?

thanks

Think about it, if you make the windows background color in it's class before creating it, the window would be black in the login screen. But once the login screen is over and the edit box comes up, (this is assuming that the edit box covers your whole screen.) you wouldn't even be able to tell that the screen is black to begin with, it's not like the edit boxs background is clear, it's white. (If it's not owner drawn that is.)

And assuming he makes an edit box at all. What if he outputs his text with TextOut()?

ahh..yea..forgot about that.
*shrug*
all ways work. here's what my main window looks like:

Why would he have spoken of an edit box it if there isn't any?

mm...on a side note, how do i determine what error code i'm getting from a windows function? like if i have LONG errorcode; and then i DO get an error code, so i have errorcode = GetLastError(); how would i figure out what error i'm getting? like if i output it to a file and i use %ld as the conversion specifier...i get a bunch of numbers like -2146893816 but if i do %c then i get 

lol thanks :)

Did you look at this or probably easier look up the error code

dude, why does there have to be so many parameters for EVERYTHING ? it would be nice if you could just be like EncryptText(sourceText, destText, encryptType); or FormatMessage(soIcanReadIt); hahaha

k, i'm done ranting :) thank you. :)


but yea..the error i got was returned from a CryptGetKey() function and the value of it that i had printed was negative and started with a 2. those error codes are all positive and end at 15999, lol
