Stretch a Picture control

[valentindvf]

How can I stretch a image in a Picture control?
Thanks

Unless your image is a metafile, the picture box doesn't allow stretching. You can use the Image control which has a stretch property, or use two pictureboxes. The following post contains a solution to sooming in a picturebox.

There is a method called PaintPicture for the Picture Box.
Example:

PicBox.PaintPicture PicBox.Picture, 0, 0, PicBox.Width, PicBox.Height

The arguments are the picture, left, top, right,bottom

Try this.

private Declare Function StretchBlt Lib "gdi32" (byval hdc as Long, byval x as Long, byval y as Long, byval nWidth as Long, byval nHeight as Long, byval hSrcDC as Long, byval xSrc as Long, byval ySrc as Long, byval nSrcWidth as Long, byval nSrcHeight as Long, byval dwRop as Long) as Long

private Sub Command1_Click()

picDest.Picture = LoadPicture("d:\windows\winlogo.gif")

End Sub

private Sub Form_Load()
picSrc.Visible = false
picSrc.ScaleMode = vbPixels
picDest.AutoRedraw = true
picDest.ScaleMode = vbPixels
End Sub

private Sub picDest_Change()

picSrc.Picture = LoadPicture("d:\windows\winlogo.gif")
StretchBlt picDest.hdc, 0, 0, picDest.ScaleWidth, picDest.ScaleHeight, picSrc.hdc, 0, 0, picSrc.Picture.Width / 26.46, picSrc.Picture.Height / 26.46, vbSrcCopy
picDest.Refresh
