View 6 RepliesThe 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

How do you convert a System.Drawing.Bitmap image to any other type of image? I tried CType, which failed, since I do not know the type for .png or .jpg. I cannot find it anywhere on google either.What is the most efficient method to do this, which keeps the quality of the image as high as possible?

View 4 RepliesI am trying to read a PDF file line by line using PDFBox.This is the first time I have ever attempted to do this with a PDF so I am not sure what I was expecting but I thought I would end up with some "mark up", which I could use to parse the lines I was looking for out of the file.
Anyway it didn't work out the way I had planned and I am not sure if that is because I am using the wrong tool or not using the right tool correctly.I managed to extract the text but I didn't really see any mark up that would be usefull to parse the file. Does anybody have any experiece with extracting test from PDFs. What tool(s) do you recomend?

View 7 RepliesI 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

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.
