I'll keep this short and simple... I asked this question before, but It wasn't answered completely. I'd like to get several images from a folder, and add them to an array.
At the top, I have:
Dim dir = New IO.FileInfo("C:Users urcotdDesktopMyImageFolder")
Dim images = dir.GetFiles("*.jpg", IO.SearchOption.AllDirectories)

I am working on a PHP site at the moment that is having trouble reading that data to display the image, so I am attempting to not only save it to the DB, but also save it as a bitmap or other file type to the actual server.
How can I create an image file (not really picky on which file type) from the "arrImage()" data above?
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 1 RepliesCurrently I'm using a picturebox object in a program which is referenced to a location on my local computer ie "PictureBox.image = Image.FromFile("c:/image.jpg")". I would like the image packaged in the .exe rather than using the file's extension. So if the exe is copied to another computer it will display fine. How can I do this? I was able to do this is the drag and drog editor by importing an image rather than specifying a location, but for my purposes I'd like it done programmatically.

View 2 RepliesBasically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1
I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:

I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

View 2 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.

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).

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
