View 2 RepliesI would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how

'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:

I know how to copy a bitmap to a picturebox.image but how do I copy the bitmap to the form?
Example:
I want to create a form 1600x1200 and put a 1600x1200 image on the form to cover the entire surface.
Then I want to put several pictureboxes 256x40 (Tool Bars) at different locations on the form.
If pictureboxA is at x32, y32 on the form, I want to copy from the form at x32, y32 256x40 to the picturebox.image then draw
the buttons on the pictureboxA.
I know how to load a .jpg or .bmp to the form from a file. This won't work for my purpose.
If there is no fix for this then the only thing I could do would be to create the bitmap then save it to a file, then reload the file to the form. I want to avoid this... It takes up time :(

I want to display a bitmap on my form, and then remove it at times, and put it back again.

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.
