Save Image in SQL Database
-
Ok, First change the following
commImage = New Data.SqlClient.SqlCommand("DELETE * FROM Images)", conImage)tocommImage = New Data.SqlClient.SqlCommand("DELETE FROM Images)", conImage)If you could then rerun the test where you had two images, what is the output now? The deletion wasn't done, because of the syntax error in SQL statement, so we don't know if the deletion works or nothello with 2 images in database msgbox1 original row count = 2 msgobx2 delete not done , rows in datatable = 2 and then i click second msgbox it shows sql exception on this under line code it shows this error Incorrect syntax near ')'. If commImage.ExecuteNonQuery() <> 1 Then MsgBox("Delete failed", MsgBoxStyle.Information) End If

Yeah, sorry. Instead of:
commImage = New Data.SqlClient.SqlCommand("DELETE FROM Images)", conImage)writecommImage = New Data.SqlClient.SqlCommand("DELETE FROM Images", conImage)There was an extra parenthesis at the end of the statement... Then let's try again -

Then let's try againhello ok no problem MsbBox1 = original image count = 1 msgbox2 = delete not done,rows in datatable = 1 msgbox3 = delete not done, rows in datatable = 1 and exit sub and then i click again so msgbox1= original image count = 1 msgbox2 = delete not done,rows in datatable = 1 msgbox3 = delete failed msgbox4 = delete not done, rows in datatable = 1 so this is the only difference waiting for your kind rep. thanks

:confused: I am missing it... For some reason seems like Fill is fetching different data... What is the connection used for filling dsImage? Is it the same that is used in deleting Another thing. I don't think we can get much further by posting through CodeProject. Is it possible for you to send me the whole project via e-mail?

hello again yes you are right and i dont mind to email this project and with empty database but size of zip folder is 42 MB so how can i e mail you ? waiting for your rep.
Wow, so big? If there's data in the database, could it be emptied. Pictures are not necessary. Also bin and obj folders are not necessary since they are created by compiler. Would that change the size say less than 5 MB. I think emailing can be done by pressing Email-link in a post instead of Reply. I'll send you a test message..

hello I have sent you mail as well so if remove bin then this will cut down up to 26mb but .mdf and log file for database both are 13 mb each but rest files are ok to attach with e mail
if you put the log and the mdf into zip folder is it still 26mb. They should compress quite well. The test message didn't come so I think we cannot use that. Also I don't know if there's any way to use attachments in cp email... Try to send me a little message to address mika dot wendelius at bdb dot fi

Hi again, What was the output from these (rowcount)?
MsgBox("Original image count in dataset: " & CStr(imageCount))
...
If (dsImage.Images.Rows.Count > 0) Then
MsgBox("Delete not done, rows in datatable: " & CStr(dsImage.Images.Rows.Count), MsgBoxStyle.Information)
End If -
Hi Mika It's done now and it's working fine so thanks for your help to solve this issue and teaching me a lot :-D :rose:
