'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:

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

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

I need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.
I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.
I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.

I am using this, however I get a GDI+ Unhandled Error.
Back when I used to use an 8 bit home computer I dabbled in machine code with an old version of BASIC which allowed you to POKE values into memory and then call the 1st memory location to execute that code. I used the equivalent HEX values for the processor which ran a series of ROR ( ROtate Right ) or ROL ( ROtate Left )commands through the carry bit as each line of the bitmap consisted of a series of bytes which were an 8 bit BYTE followed by the next BYTE in memory. The effects that I manage to create "in assembly language" as it were:
Scroll leftScroll right By manipulating full bytes in memory I created routines to:Flip the image horizontallyFlip the image verticallyTurn the image upside down Anyway, if you were to try this with the BASIC equivalent to GET and SET pixels, obviously the BASIC was a LOT slower. I am also interested in creating animated bitmaps from one or two images such as the following:Page turn effect.Sliding-in of an image in any direction.Ripple effect.Scratch effect.

I am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90

The first step will be reading the data, so I created some VB codes:
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.
' If the user clicked OK in the dialog and ' an image file was selected, open it.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.
[Code]...
The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:
