I want to convert an image to a string, then put it into 1 cell in a datagridview as a string. I've read around on the forums and I saw some people say to use StreamReader, others say BinaryReader. Well Imma try both and see how it comes out. But I'm kinda stump. I'm trying StreamReader first, and I don't know how I should even do this. This is what I've got:
Dim ofd As OpenFileDialog = OpenFileDialog1
ofd.FileName = ""
ofd.Multiselect = False
[Code]....
In my do loop, should I put it into a temp text file and then read that textfile into the datagridview? If I did that, I think it would take up some time.
I am trying to convert a TIFF image to a base 64 string.I have seen so much code on the internet like the one below, but I don't understand it .I dont know what to change so it converts my image(s).I want the outcome (the bytes) as a variable that I can use outside this function. Know how to do that?
Private Function BytesToImage(ByVal ImageBytes() As Byte) As Image Dim imgNew As Image Dim memImage As New System.IO.MemoryStream(ImageBytes)[code]..........
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

I'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.
