Displaying Bitmap

Ch1156 (2010)
I cant seem to display a bitmap on my window, i looked all over the web but i get long complicated code, im trying to keep it simple as possible. Im using a resource.rc file so i have a BITMAP control key in there but i cant load the image. Here is my code, what am i doing wrong? Also i tried MSDN but it gave me no useful Information other than the keyword. itself.

You can't have a bitmap inside the dialogbox statement in a resource like this:
1
2
3
4

12

//CAPTION "Hide"

FONT 8, "Tahoma"

STYLE 0x10CE0804
//EXSTYLE WS_EX_TOOLWINDOW // Makes Box Square



BEGIN
    CTEXT "Hide the 'Test' Box", StatText, 110,  80, 96, 15
    CTEXT "You'll notice you can click the 'Test' Button as many times as you want but when you click the \n button labeled 'Hide 'Test' Button' it will make the Test button dissappear and the box will turn grey.", StatText2, 0, 0, 300, 25
    CONTROL "Hide 'Test' Button", Hide, "Button", 0x10010000, 110,  125, 96, 15
    CONTROL "Test", Button, "Button", 0x10010000, 110,  105, 96, 15
    BITMAP "face.bmp", bmap, 110,  105, 96, 15  //******ERROR- BITMAP statement not allowed in a dialogbox  setup like this
END


You need to make a seperate statement BITMAP resource statement - and in the dialog box part you put a control statement
like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

FONT 8, "Tahoma", 0, 0, 0x1
BEGIN
    CTEXT           "Hide the 'Test' Box",StatText,110,80,96,15
    CTEXT           "You'll notice you can click the 'Test' Button as many times as you want but when you click the \n button labeled 'Hide 'Test' Button' it will make the Test button dissappear and the box will turn grey.",StatText2,0,0,300,25
    PUSHBUTTON      "Hide 'Test' Button",Hide,110,125,96,15
    PUSHBUTTON      "Test",Button,110,105,96,15
    CONTROL         IDB_BITMAP1,IDC_STATIC,"Static",SS_BITMAP,53,47,32,30
END

IDB_BITMAP1             BITMAP                  "bitmap1.bmp"



The last 4 numbers in the CONTROL statement are the x and y position and width and height of the bitmap (actually the static control that displays the bitmap).

Ok, what is IDC_STATIC and SS_BITMAP for? also my bitmap isnt displaying in the window, does it have to be the same size asd the window.

EDIT: also is there anything that needs to be in my main.cpp? i tried what is in the link and got these errors:

C:\Users\Chay Hawk\Desktop\Keylogger\resource.h|14|warning: "SS_BITMAP" redefined|

Awesome thanks!!

I think, this is the difference between Microsoft Visual Studio Resource compiler which works the
easy way I described and what ever resource compiler you are using
I just tried my two line solution in codeblocks and got a syntax error.

I use code blocks and it worked for me.
