Wondering if you already received my email with explanation in how to mask your application?

Yes I did. I was able to use the imput mask in the access database and it worked when you opened access. When I pulled that column into a datagrid it didn't bring the mask with it. So it still displayed 1234567895 instead of 123-456-7895? Is there something special that I have to do in .Net to display the input mask as well?
Thanks

We are using async socket for our client application to connect and send/receive data from the server. It works fine for most of the time but some times we get a socket exception "An existing connection was forcibly closed by the remote host". It happens when we try to senddata to the host after connecting with host.
1. BeginConnect(remoteEP, AddressOf CallSocConnect, Me)
2. BeginSend(Data, 0, Data.Length, 0, AddressOf CallSocSend, Me)
What are the common reasons for this exception?
Is it possible that we didn't even connect with the host but we tried to send data?
Thanks for any inputs..

OK here's the situation. Say we have a whole bunch of equations in the database. EG: "A + B * C". Now we get the equation and substitute values into it so we now have a string like "10 + 5 * 3".
Is it possible now to evaluate this expression without having to break the whole string into itty bitty pieces to work with? Is there some magic Execute(equation) function in .NET? 
Thanks,
Nic

Isn't that called parsing?

Not really. However someone did post a project that does what you want, although it is in C#, it could easily be rewritten for VB.NET. Runtime C# Expression Evaluator[^]. I would guess that the line that sets up the C# Compiler could easily be changed to a VB.NET compiler.

Ya, but it doesn't sound as cool as itty bitty pieces

That's great thanks  ! C# isn't a problem, I was actually just going to post the same question there

I'm relatively new to the languange, so I apologize for the newbishness exuded by this question. I'm trying to write a program where, among other things, pressing a button will take writeable text from TextBox1 to the read-only TextBox2. My problem comes when I want to have each sequential text entry on a new line. For example, I'm getting
FirstTextEntry:SecondTextEntry:ThirdTextEntry
when I want
FirstTextEntry
SecondTextEntry
ThirdTextEntry
I've tried appending Chr(13), to both the input at the time of entry and to the display window after each entry, but it makes no visible changes. Any ideas on how to accomplish this?

They say that if you play a Windows Install CD backeards, you can hear Satanic messages. That's nothing, play it forwards and it installs Windows.

You should use Environment.Newline rather than Chr(13). You'll notice that Environment.Newline adds 2 characters as is necessary in Windows.

private string imageFileName;
bool takeFirst = true;
foreach( object wiaObj in wiaPics ) // enumerate all the pictures the user
// selected
{ //wiaPics is of wiaLIB.CollectionClass
if( takeFirst )
{
wiaItem = (ItemClass) //wiaItem is of WiaLIB.ItemClass type
****line to consider***
Marshal.CreateWrapperOfType( wiaObj, typeof(ItemClass) );
imageFileName = Path.GetTempFileName(); // create temporary file for
// image
Cursor.Current = Cursors.WaitCursor; // could take some time
this.Refresh();
wiaItem.Transfer( imageFileName, false ); // transfer picture to our
// temporary file

wiaItem = (ItemClass)
Marshal.CreateWrapperOfType(wiaObj, GetType(ItemClass))
imageFileName = Path.GetTempFileName()
Cursor.Current = Cursors.WaitCursor
Me.Refresh()
wiaItem.Transfer(imageFileName, False)
pictureBox.Image = Image.FromFile(imageFileName)
takeFirst = False
End if

Hello,
I have Form1 wich loads at startup. When i press one button on this Form1, it launches Form2.
The problem occurs in when i try to exit. It will bring up a MessageBox for to ask you if i want to Exit Form2. If I press No, Form1 comes in front of Form2. Is there a way to make sure that Form2 stays upside.
Details. Form2 TopMost must stay False. Because the problem i have when it is enabled is that Form1 is activated while Form2 is in front.
Can someone help me with this.
Thanks
<br />
Private Sub Form_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing<br />
If OK2Close = False Then<br />
If MessageBox.Show("Are you sure you want exit?", "", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1, MessageBoxOptions.ServiceNotification) = DialogResult.No Then<br />
e.Cancel = True<br />
<br />
End If<br />
End If<br />
End Sub<br />

When a form calls MessageBox, the message box is shown Modally to the caller form.
It means that, until the message box hasn't moved away, you cannot access the caller form. One other thing that a modal form (here the MessageBox) does, is that it sets the focus to it's caller form, say the Parent Window.
If you call MessageBox from Form1, it will set the focus on Form1.
But to handle your problem, I suggest:
Make a Public Function in Form2 that shows the message box and returns either True if Ok was pressed or False if Cancel is pressed.
Now in the Form_Closing event of form1, instead of calling the message box, call the function in Form2 and simply check the return value!
I think this is going to solve your problem.

Can we change the background color of the listview such that we can have row 1 which can have background color as red and row2 should have background color as blue ?
Thanks
|

Try the following ,
when you are adding a item to your list view check for alternate row to apply different color.
Say if current row is odd row then write
ListView1.Items(itemindex).BackColor = (New System.Drawing.Color).Aquamarine<br />
and if it is even then
ListView1.Items(itemindex).BackColor = (New System.Drawing.Color).Bisque
Please note that this code colors background of all columns but if the last column width dosen't fills the list view then the list view background appears. So make sure that you columns fits the listview width.

How do you determine which row is ODD or EVEN?
