Displaying Image In Report, But If Textbox Is Empty Repeats Last Image?
Sep 5, 2010
I 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
i'm lost on this code.. i have a picturebox that swaps 2 images, depending on the action, file_red and file_green.. what i'm trying to to is, if a picturebox switches a image or not, to be able to detect that and have textbox8 add a line with the detection.
I'd like to verify if an image control has an image loaded . If it does , I want to unload that image (and load no image) , but if the image control has no image loaded , I want to load an image . Is it possible ?
If ImageMY.Image.Equals(Nothing) Then ImageMY.Image = System.Drawing.Image.FromFile("C:ImageBlaBlaBla.jpg") Else
im getting a image from my database to a data set. before i convert it to a proper picture i need to check whether ds.Tables("userDetails").Rows(0).Item("photo") is EMPTY or NOT. How should i write the if condition? <code>If ds.Tables("userDetails").Rows(0).Item("photo")<> ??? Then
Dim pictureData As Byte() = DirectCast(ds.Tables("userDetails").Rows(0).Item("photo"), Byte()) Dim picture As Image = Nothing Using stream As New IO.MemoryStream(pictureData) picture = Image.FromStream(stream) End Using

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.

I 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.
