I have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

View 4 RepliesBeen away from coding for almost 10 years, trying to get back into it but am a bit rusty. I have been asked to write a program that will allow users on a network to write hire data, driver data, job calander etc to a SQL database. The program works perfectly at the moment apart from one thing.
The program must allow the users to add an image to a drivers record to have on file, I have read loads of different forums, tutorials etc on how to do this and have managed to get my program to size the image properly and store it as binary data (i think) in the SQL database. I am now having problems doing the reverse and making the program read from the database and display the image in a picture box, the following is my code to save to the database
vb.net
Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
Dim strm As System.IO.Stream

I understand that there may be easier ways to do this, this is simply the way I did this years ago, if any one can give me any pointers or any tips on how to read from the DB and display the image in a picturebox

if "/images/name.jpg" exists then
<div><img src="/images/name.jpg"></div>

Seems really simple to me but NOTHING I have tried has worked (compilation errors). I've tried examples using system.io, DIM stuff with 'FileInfo', Set fs. FileInfo examples produce 'not defined' errors, 'Set' says it's outdated and not used anymore and so on.

I have a SQL Server database with a table that has a column that stores an image. I have another database and I would like to store the image from the SQL Server database into it. It's type is MS Access 2000 format .mdb.
The problem is I get back the content of the column and I put them in an array of bytes as follows:
Dim arrByte() As Byte = CType(dtAll.Rows(0)("DailyProgram_Image"), Byte())
It sends me back the data of the image as byte type. When I try to save this into the access DB it give me an error because of type mismatch.

View 11 RepliesI have a table in SQL Server with a field defined as Varbinary (MAX). In VB I am trying to save an image to the table. The file I'm using is 139kB in size and I get no errors but when I look at the record, the Attachment column where my image stream should be is empty. The rest of the information is saved. I checked the buffer and it grabs the correct size of the file (141475) so I'm very sure it's found and loaded the image.
Could the parameter from the SQL not be passing the binary value to the parameter properly?

this works fine only if an image is selected, crashes for NULL values.
I'm not sure what to use to insert a file that's located on the server into the sql database. I've read a bunch of articles but none of them show how to just grab a file without using fileupload.
