I may be saving the image the wrong way or attempting the conversion incorrectly.
In my project I am using a camera to capture images. The images will be stored in a byte array. Now I want to display my images in byte array to picture box on my form. I am pasting the code bit below.

Delegate Sub MyFrameHookerDelegate(ByVal FrameType As Integer,
ByVal row As Integer, ByVal Column As Integer,
ByRef lpImageAttribute As TIMAGEATTACHDATA, ByRef Buffer As Byte)

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.

I�m having trouble with the picturbox control, my problem in its basic form is:I have a picture Box array consisting of 9 picture boxes each with a different image in loaded at run time these are names 0.jpg to 8.jpg I then have 2 more picture Boxes named ansOne and ansTwo. I have made it so you can drag the images of these numbers to either of these picture Boxes It this next part I�m having trouble with:
I then want to have thoughs images represent a sum so when a button is clicked it adds or multiplies thoughs images together but as numbers ("badly put I know ")I am very unshore of where to start. After the image has been dragged how would I know what image has been dragged and turn that in to its integer equilivent?I had thought of using split string or something similar to just get the number before the .jpg so tried picAnsOne.imageLocation but that throghs a null reference And that�s as far as I have got.

I have manage, to allow user to browse through their files and insert an image path into a local database. The program will then retrieve the image from the image path and will be stored into ImageList. The Listview1 will then add the pictures of Imagelist into the ListView1.Items. Now my question, how can i retrieve back the path of the image when the users click on the selected image from the ListView?

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.
