Im busy making a program but it needs to send an image over a connection. Anyways, it is only possible to sends pieces of strings at the moment. And therefore I want to convert the images I want to send into strings or whatever that can be written in a textbox.Ive been trying stuff with streamreader / write but that didnt work so far.

The coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim fileSize As Integer
Dim rawData() As Byte

converting an image file into binary text in VB 2010.I am working on a compression program and need to see the actual binary as text. I have code for converting text files to binary and it works fine but, need to attempt files with greater randomness that are typically uncompressable.(JPG's) I understand that the file conversions may be huge. I plan on manipulating the binary in smaller manageable chunks.

View 7 RepliesI'm studying for a memorization-intensive exam, and have lots and lots of lists to memorize. I have a Sony Walkman that can show *.JPG files and I had an idea. I want to create some video flashcards so I can study anywhere/any time. The idea is simple: I have some text that I want to convert to an image file. No, this isn't homework for a class. My experience to date has been 100% Excel/Access/Word related, so I'm completely out of my realm when it comes to images.

View 1 RepliesIs there anyway to convert an image file bytes array into an array of the real RGB values of that image?
I don't really want to use GDI+ or the System.Drawing library, but simply apply a certain calculation/processing to every byte of the image file and get another array that contains the RGB values of every pixel in that image. I know it could be done as I know how to do it in a different programming language (Python) but not in Visual Basic.
well i convert a certain image to an icon file and when i upload it its just a white rectangle in the corner of my app instead of the actual icon???

View 4 RepliesI previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?
