I'm using the new report designer. One textbox has a long narration which causes it to spill its information into other textboxes directly below it. How can you stop this from happening?

I have a just started using VB.NEt and
have a large d drive on my computer and a small c drive.
Is there a way I can tell .Net to use
d drive instead of c drive to store my wwwroot folder?
Can I leave the inetpub folder on c?

You don't have to move your wwwroot. What you can do is create a new folder like d:\temp\blah. "blah" will be the folder containing your web app. Use the IIS admin console to create a new virtual directory called "blah" that points to d:\temp\blah. Then, go to visual studio and create a new web application in http://localhost/blah. It will use the virtual directory you supplied and put the files out on the D drive.

Hi:
I have two panels in a window form and their AutoScroll attributes are set to true. Yet I'd have one panel's HScrollBar or VScrollBar hidden so as to synchronize panel scrolling later.
Could any helper instruct me how to make it? Thanks a lot.

Hi,
I am creating tmp files everyday written as a Windows service. How would I got about deleting the tmp files from yesterday, would like only the ones created today to exist, which would then be deleted the next day?
Thanks.
-- modified at 10:32 Tuesday 22nd August, 2006
Would this make sense - if midnight then delete all .tmp files?
Thanks
|
|
|
|
|
Yeah, you created them, you should be able to delete them simply once the time rolls over.

Hello
I am referencing two DLL's from third party build in C# into my project
Both the DLL's have same Types under the same namespace, this is fine with C#
but VB.net does not seems to coupe with this. Is there any way to fix in VB.net?
Thanks

Try setting the imports statement to direct similar namespaces to an alias that is different. Either that or get to the ambiguous parts using the full namespace path instead.

Hi guys:
I am trying to compile Porter Stemming VB.NET code but it displays the error below:
The class Form1 can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again.
Can anyone help me with this? This code is from official Porter stemming site so the code should be error free. However I cannot compile it with VB 2005. I am new to VB programming so please try to explain with the code below so I know where the error is, thank you very much.

' Porter stemmer in VB.NET, translation of the CSharp port (csharp2.txt).
' The original paper is in
' Porter, 1980, An algorithm for suffix stripping, Program, Vol. 14,
' no. 3, pp 130-137,
' See also http://www.tartarus.org/~martin/PorterStemmer
' History:
' Release 1
' Bug 1 (reported by Gonzalo Parra 16/10/99) fixed as marked below.
' The words 'aed', 'eed', 'oed' leave k at 'a' for step 3, and b[k-1]
' is then out outside the bounds of b.
' Release 2
' Similarly,
' Bug 2 (reported by Steve Dyrdahl 22/2/00) fixed as marked below.
' 'ion' by itself leaves j = -1 in the test for 'ion' in step 5, and
' b[j] is then outside the bounds of b.
' Release 3
' Considerably revised 4/9/00 in the light of many helpful suggestions
' from Brian Goetz of Quiotix Corporation (brian@quiotix.com).
' Release 4
' This revision allows the Porter Stemmer Algorithm to be exported via the
' .NET Framework. To facilate its use via .NET, the following commands need to be
' issued to the operating system to register the component so that it can be
' imported into .Net compatible languages, such as Delphi.NET, Visual C#.NET,
' Visual C++.NET, etc.
' 1. Create a stong name:
' sn -k Keyfile.snk
' 2. Compile the VB.NET class, which creates an assembly PorterStemmerAlgorithm.dll
' vbc /t:library PorterStemmerAlgorithm.vb
' 3. Register the dll with the Windows Registry
' and so expose the interface to COM Clients via the type library
' ( PorterStemmerAlgorithm.tlb will be created)
' regasm /tlb PorterStemmerAlgorithm.dll
' 4. Load the component in the Global Assembly Cache
' gacutil -i PorterStemmerAlgorithm.dll
' Note: You must have the .Net Studio installed.
' Once this process is performed you should be able to import the class
' via the appropiate mechanism in the language that you are using.
' i.e in Delphi 7 .NET this is simply a matter of selecting:
' Project | Import Type Libary
' And then selecting Porter stemmer in VB.NET Version 1.4"!

I'll share a very unconventional method that professionals have secretly used for years:
Do exactly as the error message says.
Move the code for the form class so that it's the first class in the file.

Hi all,
Im using a windows form and on mouse down on a label i want to draw an rectangle on the label. Its working fine when the label without border. But When i have the label with border, after clicking the label for the fisrt time its throwing "System.Runtime.InteropServices.ExternalException" . and an Generic GDI+ Error.
In DrawRectangle function i removed the border of the control by converting the control to a label inroder to have that BorderStyle Property. I think problem might have occured in this line of code.
and its not drawing the rectangle, for the second time mouse down, its working fine and draws the rectangle properly.
Whats could be the problem, Please guide me. I was struggling with this error for the past two days. Code is given below.
Private Sub Label1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Label1.MouseDown
If CInt(Label1.Tag) = 0 Then
Label1.Tag = 1
DrawRectAngle(Label1)
ElseIf CInt(Label1.Tag) = 1 Then
Label1.Tag = 2
Label1.Refresh()
DrawCrossLine(Label1)
Else
Label1.Tag = 0
Label1.Refresh()
End If
End Sub
Private Sub DrawRectAngle(ByVal ControlName As Control)
Dim RectPen As New Pen(Color.Lime)
RectPen.Width = 6
g = ControlName.CreateGraphics()
Try
If TypeOf ControlName Is System.Windows.Forms.Label Then
CType(ControlName, Label).BorderStyle = BorderStyle.None
End If
Dim rect As Rectangle
rect = New Rectangle(1, 1, ControlName.Width, ControlName.Height)
g.DrawRectangle(RectPen, rect)
Catch ex As Exception
End Try
End Sub

hi!
im new to vb.net. and lookin for help frm u all genius working in .net

thankx in advance and help will b v v appreciate.

hi!
yup its a desktop application. actually im working on a product in which i have to give enduser the help option too.

|

Let me see a sample of your code. Maybe I can fix it if I can figure out what it is you want from it.
|
|
|
|
|
ok! actually if u can c the help of showhelp popup in msdn the same example i tried to run.
wat i gt idea from this example is that the popup help will popup on the edge of the textbox. but it is not working so. try the example in msdn.
Private Sub textBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles textBox1.KeyUp
' Determine whether the key entered is the F1 key. Display help if it is.
If e.KeyCode = Keys.F1 Then
' Display a pop-up help topic to assist the user.
Help.ShowPopup(textBox1, "Enter your first name", New Point(textBox1.Right, Me.textBox1.Bottom))
End If
End Sub 'textBox1_KeyUp

|
|

popalzai wrote: New Point(textBox1.Right, Me.textBox1.Bottom))
There's you're problem right there - the point you're creating will plot the location relative to the screen, not the textbox control or it's containing form. You have to take into account the location of the textbox on the form AND the location of the form itself.
Try this, it'll show the popup over the top right of the textbox no matter where the form is or what window state it's in (normal/maximized).
Private Sub TextBox1_KeyUp(....) Handles TextBox1.KeyUp
If e.KeyCode = Keys.F1 Then
Help.ShowPopup(Me.TextBox1, "Help is at hand", New Point((Me.Left + TextBox1.Right), (Me.Top + TextBox1.Bottom)))
End If
End Sub

thankx for reply.
but dear its not working in the mdi application.
lets suppose if u take this form as a child form then wat ?
|
|
|
|
|
Then you mess around until you get it right.
Private Sub txt_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txt.KeyUp
If e.KeyCode = Keys.F1 Then
Dim x, y As Integer
Dim r As Rectangle = txt.RectangleToScreen(txt.Bounds)
x = (r.Left - txt.Left) + txt.Width
y = (r.Bottom - txt.Top) - txt.Height
Help.ShowPopup(Me.txt, "Help is at hand", New Point(x, y))
End If
End Sub
