View 1 RepliesI have a report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.
Code I have in report
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.
Protected Sub Upload_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Upload.Click
If Me.FileUpload1.HasFile Then
Dim intWidth, intHeight As Integer
Dim UlFileName, NewFileName As String
[code].....
After an image is uploaded it is not displaying on the web page like it should be:
'*** View Images ***'
Me.imgPicture.Visible = True
Me.imgPicture.ImageUrl = NewFileName
In my aspx page I have a gridview which displays the value from my database as "*". So if a value in my database table is 5, it will be displayed as "*****" in the gridview.
code in aspx:
<asp:TemplateField HeaderText="Rating" SortExpression="Rating">
<ItemTemplate><h1><%# getrating(Eval("Rating"))%></h1></ItemTemplate>
</asp:TemplateField>
code in aspx.vb
[Code]...
What I want to do is change that "*" to a picture, ie star.jpg, so in the gridview it will display the image star.jpg instead of "*".Using MS visual studio 2010
I am using vb.net running a backend MS.Access database and I am wondering what is the code that I can use to display a picture of an image when the field name is selected.My MS Access "field" name is Cars_Types: in the files I have the data "GM, Chrysler, Toyota, Honda, and Ford". The name of my database is ModelCars.accdbThe pictures are not coded into the database instead I would like them to be coded into the VB.NET program.

View 14 RepliesI have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.

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.
