怎样将一个已知HBITMAP的图象画到DC上？(100分)

我用LOADBITMAP一个图象资源，得到了HBITMAP，却不知道怎样画到窗体的DC上，请教，请完全用API来说明，谢谢。

BitBlt(DC, 0, 0, 100, 100, HBITMAP, 0, 0, Bitmap.Width, Bitmap.Height);

这样写不行，我试过了，HBITMAP不能当HDC用。

HRESULT Draw(<br><br>&nbsp; &nbsp; DWORD dwAspect, //Specifies how the object is to be represented<br>&nbsp; &nbsp; LONG lindex, //Specifies the part of the object to draw<br>&nbsp; &nbsp; void * pvAspect, //Always NULL<br>&nbsp; &nbsp; DVTARGETDEVICE * ptd, //Specifies the target device in a structure<br>&nbsp; &nbsp; HDC hicTargetDev, //Specifies the information context for the target device ptd<br>&nbsp; &nbsp; HDC hdcDraw, //Identifies the device context on which to draw<br>&nbsp; &nbsp; const LPRECTL lprcBounds, //Specifies the rectangle in which the object is drawn<br>&nbsp; &nbsp; const LPRECTL lprcWBounds, //Specifies the window extent and window origin when drawing a metafile<br>&nbsp; &nbsp; BOOL (*) (DWORD) pfnContinue, //Callback function for canceling or continuing the drawing<br>&nbsp; &nbsp; DWORD dwContinue //Parameter to pass to the callback function pfnContinue <br>&nbsp; &nbsp;

大哥，给给DELPHI的例子好吗？<br>这个函数里我怎么没看见在哪赋HBITMAP这个参数？

TBitmap类的Handle就是<br>HDC我一直就这么用

你可以这样：<br>1、创建一个Tbitmap；<br>2、设置Bitmap.handle:=HBITMAP<br>3、不用我说了吧？有多种方法绘制bitmap，比如用BitBlt（bitmap.canvas.handle）

你们还是没懂我的意思，我是完全用API编制的程序，根本就没用到DELPHI的类，更不用说TBITMAP了，前面我已经指明是HBITMAP了。

能否将代码帖出来看看？<br>

var Bmp: hBitmap;<br>begin<br>&nbsp; Bmp:=LoadBitmap(hInstance, 'WENX');<br>&nbsp; 然后从这里开始画...,用什么函数？<br>end;

在VC++中有个函数：<br>BOOL WINAPI DrawState(<br>&nbsp; HDC hdc, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // handle to device context<br>&nbsp; HBRUSH hbr, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// handle to brush<br>&nbsp; DRAWSTATEPROC lpOutputFunc, &nbsp;// pointer to callback function<br>&nbsp; LPARAM lData, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// image information<br>&nbsp; WPARAM wData, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// more image information<br>&nbsp; int x, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // horizontal location of image<br>&nbsp; int y, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // vertical location of image<br>&nbsp; int cx, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// width of image<br>&nbsp; int cy, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// height of image<br>&nbsp; UINT fuFlags &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // image type and state<br>);<br><br>可以完成这个功能，但是我在DELPHI中使用时总是报错。<br>我在VC中的一条语句：<br>DrawState(hdc,null,null,(LPARAM)bitmap1,0,32,32,0,0,DST_BITMAP);

procedure TForm1.FormPaint(Sender: TObject);<br>var<br>&nbsp; DC : HDC;<br>&nbsp; HBMP : HBITMAP;<br>&nbsp; BITDC : HDC;<br>&nbsp; Pal: tagLOGPALETTE;<br>&nbsp; Palette : HPALETTE;<br>begin<br>&nbsp; DC := Form1.Canvas.Handle ;<br>&nbsp; HBMP := LoadBitmap(0,PChar(OBM_CHECKBOXES));<br>&nbsp; BITDC := CreateCompatibleDC(0);<br>&nbsp; SelectObject(BITDC,HBMP);<br>&nbsp; BitBlt(DC, 10, 10, 100, 100, BITDC, 0, 0, SRCCOPY);<br>&nbsp; DeleteObject(HBMP);<br>&nbsp; DeleteDC(BITDC);<br>end;

同意楼上，同样用DRAW,StretchBLT也可.[]

谢谢realLearning，也谢谢大家，请多指教了。
