View 6 Replies I have a web app that allows users to upload images. Last week, all was well. This week, it appears the code is breaking. Here is the code:
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
If FileUploadControl.HasFile Then
Dim month As String = ddlMonth5.SelectedValue
Dim year As String = ddlYear7.SelectedValue
' Dim whatis As String = FileUploadControl.PostedFile.ContentType
Try
If (FileUploadControl.PostedFile.ContentType = "image/jpeg") Or (FileUploadControl.PostedFile.ContentType = "image/pjpeg") Or (FileUploadControl.PostedFile.ContentType = "image/gif") Or (FileUploadControl.PostedFile.ContentType = "image/x-png")
Then
Dim fs = New FileStream(FileUploadControl.PostedFile.FileName, FileMode.Open, FileAccess.Read)
'save file with new size
Using image As System.Drawing.Image = System.Drawing.Image.FromStream(fs)
Using bitmap As New Bitmap(image)
bitmap.Save("C:WebsitesimagesCusRespData.jpg", image.RawFormat)
bitmap.Save("C:Websitesimages" & month & year & "CusRespData.jpg", image.RawFormat)
End Using
End Using
StatusLabel.Text = "Upload status: File uploaded!"
fs.Close()
fs = Nothing
Else
StatusLabel.Text = "Upload status: Only .jpg,.jpeg,.gif and .png files are accepted!"
End If
Catch ex As Exception
StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " & ex.Message
End Try
StatusLabel.Visible = True
End If
End Sub
On the development side, I see this error: The file could not be uploaded. The following error occurred: Could not find a part of the path. On the production side, this occurs: The following error occured: A generic error occurred in GDI+.

I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
i want to store 1st item.value of dropdownlist on page load.
but it is not allowing:
-The text property of the textbox has got the value you typed, despite viewstate false
-The checkbox.checked property is true, despite viewstate off
- And the selectedValue property of the dropdown is "", no matter what you chose. And to avoid obvious stuff, in fact putting a break point on the load method of the page, just before clicking the button would have shown the same thing...
