Hi.
I'm making an application that reads the contents of the clipboard when it changes, and looks for specific values. I've read posts describing how the windows hook chain works, and this seems like the best approach. But I don't understand how to hook onto the chain or have my procedure run when clipboard changes.
EDIT:
I found a page describing exactly how to hook on to the chain here. The result works like it's supposed to, but not in the way I meant to. A part of the code is constantly running, thus using more resources on the computer than I intended to. Not a big deal, but you know... Always searching for the perfect solution 
I had hoped that there was some way to make windows run a sub ONLY when the contents of the clipboard changed. This works fine for now, but I'm still looking for another solution. I'm still hoping for lots of advices 
Sincerely, Erik.

Hello experts,
I am trying to create simple report viewer in VB.NET (VS 2003)
I put CRViewer control on the form and trying to assign .rpt file name to the ReportSource property
But it doesn't work - i get message "Load report failed."
I tried to download sample applications from BusinessObects Support site but all samples are using "build-in" reports. and I need to open .rpt file from the disk.
Please help.

I have a form in a software program where the user can type in their information. When the zip cod form field is empty and I submit the form I get an error that says the string is in the wrong format, but when the field is filled in I don't get the error.
How do I check to see if someone has filled in a text box in the form or if it is empty?
|
|
|
|

try this:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox3.Text = "" Then
MsgBox("You Must put something in here first")
Exit Sub
End If
continue on with your program stuff here........
End Sub

You might have Google it before you post it. Anyway here's something that you can use for your purpose.
' Validate a US ZIP code
' Example:
' MessageBox.Show(IsValidUsZip("12345")) ' => True
' MessageBox.Show(IsValidUsZip("12345-1234")) ' => True
' MessageBox.Show(IsValidUsZip("12345-12345")) ' => False
Function IsValidUsZip(ByVal zip As String) As Boolean
Return System.Text.RegularExpressions.Regex.IsMatch(zip, _
"^(\d{5}-\d{4})|(\d{5})$")
End Function

I have a windows application where a form opens another form, as showe din the code below:
Public Class frmForm1
dim frmMyForm2 as frmForm2
public sub OpenForm2
If frmMyForm2 Is Nothing Then
frmMyForm2 = New frmForm2()
frmMyForm2.MdiParent = Me.ParentForm
frmMyForm2.Show()
Else
frmMyForm2.BringToFront()
End If
end sub
end class
As you can see, if form2 is nothing then a new instance is created and displayed, else it is bought to the front.
Problem arises when I close form2 and then try to re-open it from form1. Although the form is closed it still isn't equal to nothing, therefore, else clause is executed which obviously isn't any good.
Any ideas?

Have you tried dispose in form2 when closing?
frm2.close()
frm2.dispose()
That should get rid of it, or you could just hide it.#
hope this helps

Yes, I have tried disposing, but for some reason that doesn't make form2 equal to nothing, so again, the else clause is being executed.
Maybe I should just hide form2 instead of closing it then.
Thanks for your help.

Hi,
Liqz wrote: for some reason that doesn't make form2 equal to nothing
whatever the class, there is not a single method that can set a reference to Nothing.
Close() does not, Dispose() does not, Hide() does not.
the only thing that makes form2 equal Nothing is a statement such as
form2 = Nothing
You have two ways to solve your problem:
1.
never call close; just work with Hide() and Show()
2.
make sure you apply form2 = Nothing whenever you close form2.
|
|
|
|
|
But I would have to execute 'form2 = nothing' from form1, how does form1 know when form2 is closing?
|
|
|
|
|
If form1 is interested in what happens to form2, it could subscribe to its events,
in your case the Closed event.
|
|
|
|

Lets say that you have a form called Form1 and you want to check to see if it is open first so you dont have multiple instances of the form running around on your end user's desktop.
First we make a Class statement and define your Form1 as FormNumberOne with events:
Dim WithEvents FormNumberOne As Form = Form1
Then under an action like a menu item click or something we drop this if statement:
If FormNumberOne Is Nothing OrElse FormNumberOne.IsDisposed Then
Dim FormNumberOne As New Form
FormNumberOne = Form1
FormNumberOne.Show()
ElseIf FormNumberOne.Visible = False Then
FormNumberOne.Show()
Else
MsgBox("You already have the form number one open")
End If
Give this a try, should be what you are looking for...

I have a dataset containing 2 tables, PLSupplierAccount and PLProposedPayment, which contain related data. I have created a relationship between the two table.
I now need to execute the following sql statement, and return a single recordset/table of the data.
SELECT * FROM PLSupplierAccount INNER JOIN PLProposedPayment ON PLSupplierAccount.PLSupplierAccountID = PLProposedPayment.PLSupplierAccountID
Not sure how to do this, and Google[^]"> was not much help.
Any help appreciated (as always)

Try this:
SELECT PLSupplierAccount.*,PLProposedPayment.*
FROM PLSupplierAccount INNER JOIN PLProposedPayment ON PLSupplierAccount.PLSupplierAccountID = PLProposedPayment.PLSupplierAccountID
But change PLSupplierAccount.*,PLProposedPayment.* for the columns you really need - its not good practice to do a select *, although I often use it for code examples

Thanks for the reply, but it's not the SQL statement I am having trouble with. I need to return the data from a DataSet i.e. execute the select statement against the dataset and get the results as a single datatable.

Sorry, I misunderstood. Personally I would be tempted to requery the database and create the new table that way.
This may help, but I have not tried it myself. I'm kind of old fashioned, I like to let sql do the work for me whenever I can Microsoft Article

so you need to drop the combined dataset into an array, then loop through the array and assign each line to a pre-built internal data table?

Thats Microsoft's solution not mine I would requery the database and create the new table that way
