mfc中添加背景圖片

1、方法一：1、聲明成員變量CBrushm_brush2、在InitDialog中添加代碼：CBitmapbmpbmp.LoadBitmap(IDB_BITMAP1)IDB_BITMAP1是圖片資源IDm_brush.CreatePatternBrush(3、重載對話框的OnCtlCol，改最后的返回值：1return(HBRUSH)m_brush方法二：把下面這段代碼加進OnPaint()里就行了CPaintDCdc(this)CBitm

2、apbitmapbitmap.LoadBitmap(IDB_BITMAP1)這個IDB_BITMAP1要自己添加CBrushbrushbrush.CreatePatternBrush(CBrushpOldBrush=dc.Object(dc.Rectangle(00200200)這些參數(shù)可以調(diào)整圖片添加位置和大小dc.Object(pOldBrush)方法三：使用StretchBlt（）函數(shù)，具有圖像自適應(yīng)窗體功能CPaintDCdc(
