Need help with Bitmap Display

This code is expanding on the forger's windows programming tutorial; bmp_one (simply displays a static bitmap of a ball on a screen).

I am attempting to load an array of HBITMAPS (deck[53]) with a bunch of bitmaps of playing cards I scanned earlier today.. and display 5 random cards from the deck onto the main window.

I can get the code to work if I omit trying to load the deck[53] and just btblt( ) one specific card.

Can anyone spot the problemo...?? :confused:

using codeblocks v8.02

I get the message box to finally stop displaying.. after I change the loop value from 53 to 51.. but it doesn't make sense... there are 52 cards in the deck + 1 bitmap of the back of a card...

Code:

---

for(int i=0, j=ID_2OFSPADES; i<51; i++, j++)
                {
                  deck[i] = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(j));

                    if(deck[i] == NULL)
                    {
                        MessageBox(hwnd, "Could not load cards!", "Error", MB_OK | MB_ICONEXCLAMATION);
                    }
                }

---

What does GetLastError() have to say when LoadBitmap returns NULL?

Do you have anyother resources with the IDs of 151 or 152 etc?

EDIT: You seem to be missing location of the image for the ace of diamonds

I prefer...

Code:

---

for(int i=0;  i<53; i++)
{
          deck[i] = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE( ID_2OFSPADES + i ));



int iCard=0;
int iGap=5;//put a gap of 5 pixcels between the cards
for (int i=0; i<5; i++)
{
            iCard=rand()%53;//check the edge cases here
            //error check for valid image in array

            hbmOld = (HBITMAP)SelectObject(hdcMem, deck[iCard]);

            GetObject(deck[iCard], sizeof(bm), &bm);

            BitBlt(hdc, 100 + (i*(bm.bmWidth+iGap)), 100, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY)
}

That missing bitmap location in the resource script solved a lot of me' problems.. thanks novacain.

My next task I would like to accomplish is to have a card bitmap display to the window whenever the, "HIT ME!" button is pressed.. everything looks alright to me... but whenever I press the button, nothing happens. Any suggestions..?? :confused:

I just remembered that creation/usage of Device Context can only occur in response to a WM_PAINT message.. I was trying to display bitmaps from WM_COMMAND... :rolleyes:

Just want to thank everyone who helped me out with some basic windows programming... just completed my first program that uses bitmaps. I would be interested in ya'lls opinion; maybe there is a better way to do some of these things.

After the code was complete, I took the idea of seperate compilation to the extreme. According to my CS101 professor, the main( ) function of a program should be as streamlined as possible to hide as much data as possible. I split the project up into 5 different files: resource.h, resource.rc, blackjack.h, blackjack.cpp, and main.cpp. Notice how little code there is in main.cpp.

Lessons Learned: Thou shalt not attempt to device context outside of WM_PAINT.
The importance of "compiling/testing as you go"

One area of concern though: although my program appears to run fine, I am not sure if I am deleting all my DC's properly... I store the returning value from SelectObject( ) into a class global "hbmOld" and then at the end of the wm_paint, I delete whatever functions used the DC.. (I hope).
