I 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
My goal is to find the fastest way to convert a bitmap in a one-dimensional string array, where black pixels have to be converted in "X" characters and every other pixel in blank characters.My present attempt is to use a code like:
[code]...
But the Cpu usage is excessive, and the elaboration time too (I have to convert one Image by second).Can someone suggest a much more fast method, maybe using some Api??
I designed a complicated graphic that draws on a Visual Basic screen. But how can I transfer the image to a bitmap or some other format that I can post on the Internet?

'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:
'---save the video data into the Image global variable--- Public Sub CaptureImage() Dim data As IDataObject Dim bmap As Image Dim ms As New IO.MemoryStream() '---copy the image to the clipboard--- [Code] .....
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.

I have created an shareware application using vb.net visual studio 2008 for windows desktop, and packaged it using innosetup 5.3.8. The problem is when i have installed the application in C:Program FilesApplication and it runs successfully(use trial period of the application), Im also able to install the application once again freshly with the same setup by installing in different directory.eg C:Program FilesApplication new . The application in C:Program FilesApplication new does not have any settings of the already installed one.
Where do i went wrong . Do i need to take care of this in my application(vb.net) or innosetup. How to take care of the already installed path in innosetup or carry the settings of already installed application to newly installed path by upgrading the older one.
I dont want to write any thing in registry because the application does not want any administrative permission requirements.If i install the application in same path it gets updated with the older settings being taken over to this new one and it works fine.
I have a grass image located here in my directory. I want to just create a Bitmap, but I am getting an error. (Parameter is not valid.) Immediate Window: A first chance exception of type 'System.ArgumentException' occurred in System.Drawing.dll
I understand there are no pointers in VB.Net. I need to use something similar.The issue is that I have a structure that represent a deck of cards, with elements showing how many of each type of card there is. So I have my_deck.ace, my_deck.two, and so on.What I want to do is set a pointer called current_element that refers to any element in the structure. It may one time point to my_deck.three, and another time to my_deck.nine, and so on. It could point to any element.What I want to do is, for instance to set current_element to point to my_deck.ace, then decrementing current_element would reduce the count of aces by one.[code]that would work, but it's inelegant, I have about 30 different operations to perform, some of them using several lines of code. I'd like to avoid this if at all possible. I could tolerate doing it 2 or 3 times, but not 30.
