Hi,
Is it possible to remove the last line from the datagrid where you enter new row values (*) but still be able to edit the grid. Basically I want to be able to only edit the datagrid not add any rows to it.
Thanks!

Hi,
I am working on Media File Steam Edition, and want to cut a file into many, and join two files. I am using DirecX9 SDK. I tried hard, but cant go on further with my own knowledge.
Can any knowledged person guide me for the same. I was working on .avi files, but now am thinking of .wmv files.
Any thing that can help me do the coding for joining and cutting media files will do.
Thanks, 
Jc Shreyash Singh Parihar

Trying to work with the tab control in Visual Studio 2005. I am certain I am missing something painfully obvious, but how do I hotkey the tab pages?
Also, can anyone explain how I can move a panel from one tab page to another when a new tab page is selected?
Thanks...

Well, I figured out one of my questions. I can move controls from page to page via the code: [control].Parent = [Tab].SelectedTab
I'm still embarassingly stumped on the hotkey situation however. I will be much obliged when I am appropriately humbled....

Well, I'm not so embarassed anymore since the solution to my issue is a little trickier than I first imagined. At any rate, in case anyone is ever interested, the class below will create a tab control that can be hot-keyed.
Public Class MnemonicTabControl
Inherits TabControl
Public Sub New()
Me.DrawMode = TabDrawMode.OwnerDrawFixed
End Sub
Protected Overrides Function ProcessMnemonic(ByVal charCode As Char) As Boolean
Dim i As Integer
For i = 0 To TabPages.Count
If (Control.IsMnemonic(charCode, TabPages.Item(i).Text)) Then
Me.SelectedTab = TabPages.Item(i)
Me.Focus()
Return True
End If
Next i
Return False
End Function
Protected Overrides Sub OnDrawItem(ByVal e As DrawItemEventArgs)
MyBase.OnDrawItem(e)
Dim g As Graphics
g = e.Graphics
Dim sf As StringFormat
sf = New StringFormat()
With sf
.HotkeyPrefix = Drawing.Text.HotkeyPrefix.Show
.LineAlignment = StringAlignment.Center
.Alignment = StringAlignment.Center
End With
g.DrawString(Me.TabPages(e.Index).Text, Me.Font, SystemBrushes.WindowText, Me.GetTabRect(e.Index), sf)
End Sub
End Class

hi,
I think ... if you are getting a problem with only one .png file then it might be that the file format is unrecognised.or the image file is missing....
Apart from that i dont think there shud be any problem.
Hope it helps ...
bye

I don’t find any errors in your code, but make sure that you declare your game form correctly with New keyword. Like
Dim game As New Form2

Use the FORMAT function on the value u are inserting into the datagrid.
e.g Format(txtDate.text, "%M/%d/yyy"), also search in help menu for format function as gives u plenty of examples
hope this helps

How to increase the maximum number of error count in the error list window of VB.net? By default it's only 100 error per compilation. Iam migrating application from VB6 to VB.Net2005. So, i got more than 1000 errors which can be seen in the upgraded report.html. Am not able to predict the how many errors are corrected or remaining. So please help me.

You probably can increase the number of errors reported, but even if you do, the total number or errors reported is hardly interresting. When you have so many errors in the code, most of them will be the result of previous errors in the code. For an example, if the declaration of a variable contains an error, there will also be an error for every time that variable is used.

Hey!

will this code work?
<br />
<br />
Dim cal As New System.Globalization.GregorianCalendar<br />
<br />

If i set the year to 2007 and get the week nr from week 13(2007-03-26) to week 12(2008-03-17) then it counts the weeks wrong
2007-12-31 - 2008-01-06 is becoming week nr 53!? there is no week nr 53 in 2007.
And thanks to this error the next week is missing(Week 1 2008(2008-01-07 - 2008-01-13))

Yes, the week number is wrong for certain dates when using the ISO standard calendar.
I have created a method that can be used as a replacement. You can get it from my code archive[^].
