I know that controls for WinForm and WebForm
are come from different classes even they shares
similar name such as ListBox.
BTW, anyone can guide me that does it possible to
convert existing WinForm to WebForm application?
Any tools or techniques are welcome.
Thanks in advance.

Because the way a Web application works is very different from a Windows Form, your best bet is to rewirte your app form scratch. If it was written properly in Windows Forms, you should only have to rewrite the user interface. Any database code should be in seperate classes, that way they can be shared between the two, usually without any modification.

As long as the other computers simply have the .NET Framework installed, your programs should work fine.

You must install the .NET Framework on each PC that your .NET application is to run on.

Yes. Install the .NET Framework on each PC that your application is to run on.
Remember. Visual Studio IS NOT the same as the .NET Framework.

Please anybody who know and tell me the simple program for insert, edit, cancel and delete using ADO in VB6, I have to learn it from the first, but currently I use the Data Control for insert, edit,cancel and delete. The provider = microsoft.jet.oledb.4.0.
 ;);P

Simple? Anything but... Articles and samples concerning VB6 and ADO are becomming increasingly difficult to find over the last three years. They've been pretty much replaced by VB.NET and ADO.NET. Your best bet is to pick up a book on it. Believe it or not, "Visual Basic 6 Database Programming for Dummies" has turned out to be pretty good on the subject.

I read on www.visualbasic.net[^] that I could send mail messages by using the objects available in System.Web.Mail, so I tried including the line Imports System.Web.Mail at the top of my code, but there was no System.Web.Mail!  So is there any way to send e-mails using a different method in VB .NET?
O_o

In order to use the System.Web.Mail namespace, you have to add to your project, a reference to the System.Web.dll assembly. Go to your References folder in the Solution Explorer, right-click the References folder, then click Add Reference. On the .NET tab, scroll down the list until you find System.Web.dll and double-click it. The reference should appear in the bottom window of the dialog, then click OK. Now you can add the Imports System.Web.Mail at the top of your code.

When I shift to a tab page and turn to the previous again, selectedIndex changed event is triggered for comboboxes on newly focused tab. When I shift to another program and come back to program form key up events are fired! To prevent this I used boolean flags but isn't this behaviour stupid? There must be a more elegant solution.
Thanks a lot.

Thanks. It seems that our boolean flags will stay in the code.

Hello all,
I'm trying to change the color of the text of a DateTimePicker, just the text that appear in the control after we clicked in a date on the calendar.
I've already used the ForeColor and it didn't work and I tryed the CalendarForeColor and they changed the color of the calendar, not the text that I'd like to.
What should I do.
Thanks.

hello there -
i have two applications. the first one save a bitmapfile to a certain directory.
the second one just reads this bitmapfile into a picturebox.
the first time everything works fine.
but as soon as the first application wants to write again the file to the same path and filename, an exception is thrown. i know why, because application two seems to have the bitmapfile protected from overwriting, because it uses it in the picture box.
but i want to have the actual bitmap in the picturebox. any idea how i can solve my problem?
Save-Function of Application 1:
picPath = "\\Matrix\Kunden\server.bmp"
getScreenShot._getImage.Save(picPath)
Read-Function of Application 2:
path = "\\Matrix\Kunden\server.bmp"
Me._schoolMain.Screenshot.Image = screenShot.FromFile(path)
thx for any help.

Your having this problem, not because the image is shown in a PictureBox, but because the Bitmap object in your 2nd application is keeping an open file handle to the image file that your loading.
The workaround can be found here[^] on MSDN.

well, thank you for the link. i tried it this way but something i seem to do wrong ...
here the code:
Public Sub _getClientScreenShot() Implements IServer._getClientScreenShot
Dim user As IClient
Dim path As String
Dim screenShot, screenShotTemp As Bitmap
Dim screenGraphics As Graphics
For Each user In _clients.Values
Try
user._captureScreen()
path = "\\Matrix\Kunden\" + user._computerName.ToString + ".bmp"
screenShotTemp = Image.FromFile(path)
screenGraphics.FromImage(screenShotTemp)
screenGraphics.DrawImage(screenShot, 0, 0)
screenShotTemp.Dispose()
screenGraphics.Dispose()
Me._schoolMain.Screenshot.Image = screenShot
Catch e As Exception
Me._schoolMain.Info.Text = "Exception in Screenshot: " & e.ToString
End Try
Next
End Sub
unfortunately, the failure got worse. the application that calls this function hangs up...
what did i wrong?

First, you don't need to call .ToString here. _computerName is already a String and doesn't need to be converted to one.

screenGraphics.FromImage(screenShotTemp)
screenGraphics.DrawImage(screenShot, 0, 0)
screenShotTemp.Dispose()
screenGraphics.Dispose()
Me._schoolMain.Screenshot.Image = screenShot
Second, you're doing alot of unecessary work and this is where your hanging up. All you need to do is load the picture into your screenShotTemp and make a copy of it using a new Bitmap object. Then use the copy as your PictureBox source image and release the original image in your temp variable.
Dim screenShotTemp As Bitmap
Dim path As String
.
.
.
path = "\\Matrix\Kunden\" + user._computerName + ".bmp"
screenShotTemp = Image.FromFile(path)
Dim screenShot As New Bitmap(screenShotTemp)
PictureBox1.Image = screenShot
screenShotTemp.Dispose()
The Bitmap class has about a dozen different constructors. Read up on them here[^].

I am trying to print a mschart from a vbnet project.
In vb6 it was easy:
MSChart1.EditCopy
Printer.PaintPicture Clipboard.GetData(), x, y
But vbnet no longer has a printer object.
I have tried:
Clipboard.SetDataObject(Me.MeanChart)
e.Graphics.DrawImage(Clipboard.GetDataObject, Y)
DrawImage does not take the argument.
Need help
Thanks ahead
