VB.net Clipboard problem.

[Dotnetprogrammer]

Hi all I have a simple question. I want a way of determining if Jpeg of GIF pics are in the clip board. VB.net allows us this to us for Bitmaps but how can I determine or get data from clip board of type Jpeg of GIF. Thanx in advance for your help.

This way I can read in bitmaps but how to check for Jpeg or Gif

Me.PictureBox1.Image = Clipboard.GetDataObject.GetData(DataFormats.Bitmap)

Image.RawFormat

 

[Dotnetprogrammer]

Thanx for the reply can you give me a small example as to how can I use this image.Rawformat.
in the code I have given above

 

[vis781]

If Me.PictureBox1.Image.RawFormat.Equals(System.Drawing.Imaging.ImageFormat.Jpeg) Then
 
Messagebox.Show("This is a Jpeg")
 
End If

Thanx for the reply once again. Can you kindly tell me as to how to check for jpeg images on Clipboard? then read it on to the picture box.

Kindly give a small example.

I have an application which can see a bitmap on the clipboard, but i have tried lots of methods to find out if it is a jpg or gif but they always return "memoryBMP" or "BMP" format.

I haven't even tested this so don't shhot the messenger...

if  Directcast(Clipboard.GetDataObject().GetDataPresent(DataFormats.Bitmap)), 
Bitmap).RawFormat.Equals(system.drawing.imaging.Imageformat.Jpeg) then
 
...
 
end if

A really long shot. But try that until i can figure out how to read the header of file on the clipboard.

 

[Dotnetprogrammer]

Ok thanx for the reply let me test it...I hope we can figure out some way...as this is really driving me crazy

Looking into it further it may just be that the only way to do it is to load the image into a bitmap object and then determine the format. It seems the clipboard's predefined formats don't extend to image formats.

 

[Dotnetprogrammer]

Ok I agree...but how can we determine the format after loading the image into a bitmap object?

Use the RawFormat property in my earlier post.
