Sounds like you need to rethink your design. 2000 controls on a form ? You're kidding right ?

2 minutes with 2000 controls on a mobile device is freakingly fast, if you ask me.... 
|
|

The only way to make it faster is to rethink your design and GREATLY reduce the number of controls you're using on this form. 2,000 controls is just an insane number to put on a form. Creating a new instance of a control is a very expensive operation and there is simply no way to speed that up.

By using a third party component, or writing the code yourself.

I have written much code in VBA and now I wanted to explore Visual Basic 2005.
My objective is to be able to open an excel file and to plug in a value in range ("A1") in the excel worksheet/workbook from a Visual Basic 2005 form.
Any help/sample code would be tremendously appreciated.
Thank you,
Gray

Silly me, I forgot to save the document.
To do this, use workSheet.Save or workSheet.SaveAs(fileName).

Thank you so much Justin! It works and I couldn't be more thankful.
Again, thank you very much.

I created an SDI application with one form and one ListView control and loaded the data, showing by Groups, here is the code:
Me.ListView1.BeginUpdate()
With Me.ListView1
.View = View.Details
.Items.Clear()
.Columns.Clear()
.MultiSelect = False
.FullRowSelect = True
.GridLines = True
.ShowGroups = True
End With
If Me.ListView1.Columns.Count = 0 Then
Me.ListView1.Columns.Add("Request", 100, HorizontalAlignment.Left)
Me.ListView1.Columns.Add("Description", 200, HorizontalAlignment.Left)
Me.ListView1.Columns.Add("Date", 75, HorizontalAlignment.Center)
Me.ListView1.Columns.Add("Approver", 100, HorizontalAlignment.Left)
Me.ListView1.Columns.Add("Status", 100, HorizontalAlignment.Left)
End If
While (Reader.Read)
dt = CDate(Reader("RequestDate"))
ReqDate = String.Format("{0 }", dt)
Me.ListView1.Groups.Add(Reader("RequestedBy"), Reader("RequestedBy"))
Dim listItem As New ListViewItem(Reader("RequestNumber").ToString)
listItem.Group = Me.ListView1.Groups(Reader("RequestedBy").ToString)
listItem.SubItems.Add(Reader("OrderDescription").ToString)
listItem.SubItems.Add(ReqDate)
listItem.SubItems.Add(Reader("NextApprover").ToString)
listItem.SubItems.Add(Reader("StatusDescription").ToString)
Me.ListView1.Items.Add(listItem)
End While
Me.ListView1.EndUpdate()
The results were as expected, but when I added this form to my MDI app, where it is supposed to be used, it does not display the groups, but the rest of the column data is displayed fine. I have tried everything I knew off but no luck.
I will greatly appreciate if someone could offer any suggestions. Thanks.

Are XP Visual Styles turned on in this project?? If not, the groups will not render. Grouping is only supported under Windows XP and above and only when EnableVisualStyles is turned on.

Dave,
Thank you so much for your help. I bet that is the reason because I am using Sub Main in a code file instead of a Form as the Startup Object. Since my posting I created another MDI application to test, this one uses a Form as the Startup Object and the EnableVisualStyles is turned on and I am able to see the Groups. I would never have thought about that. Thanks again.
Sincerely...Faruk

It's documented in the Groups Property[^] docs on MSDN and in the MSDN Help with Visual Studio. i know it's not the most obvious place to see this...
But, when you run into a problem like this, start reading the docs on each property and method that you're using and look for these little quirks, especially in the Notes and Exceptions sections. Stuff like this bites people all the time, even the pros at Microsoft.

 Does anyone out there know how to save an image directly from a webbrowser control once a page is loaded?
I am not looking for a way to "re-download" the image based on the src value, because I can do that.
I was thinking more along the lines of copying the image from the webbrower control into the clipboard and then saving it.
The reason for this is, some sites only alow you to view thier pictures, when you are browsing thier site, so if you download the image directly, you get a different image.

Justin,
No, I don't know of a way to save just a particular image, but you could save the whole webpage, as in this code[^].

Thanks, I will download it and check it out.
