I have a button on a form that's sole purpose is to lauch a new instance of another form.
Private Sub btnFigure7_1_Click(ByVal sender As System.Object, ByVal e _
As System.EventArgs) Handles btnFigure7_1.Click
Dim Figure7_1 As frmMap
Figure7_1 = New frmMap
Figure7_1.Show()
End Sub
I would like for the form to be showed only if it is not visible. Currently it can be opened as many time as the user hits the button.
Any Help?

Why dont you use a variable......such that set the variable when you create an instance of the form and reset it on closing that form or what ever may be the requirement
Got it......?

Replace all your Figure7_1 code with this.
Figure7_1.show

I have one last line of code to write then this project is complete. I have spent 2 weeks on this "Last Line" .... 
Trying to read the contents of a datagrid to Excel:
This works if the column is simply a bound column:
For i = 0 To StatusGrid.Items.Count - 1
worksheet.Cells(i + 2, 1) = StatusGrid.Items(i).Cells(1).Text()
Next
However, for Template columns, the following SHOULD work, but does not:
For i = 0 To StatusGrid.Items.Count - 1
worksheet.Cells(i + 2, 2) = CType(StatusGrid.Items(i).Cells(2).Controls(0), DataBoundLiteralControl).Text()
Next
I get the following error:
Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.DataBoundLiteralControl'.
I am at my wit's end on this one... Can anyone help?

I want to send email out through my application.
I found a way using System.Web.Mail but when I make a reference to it I get the blue jagged under line. I think its because I'm missing the proper dll? I have Windows XP Home edition and Visual Basic Standard edition. How can I get this to work or are there other options?
Thanks again.

Did you set a reference to the System.Web.dll? If not, right-click the References folder of your project, then click Add Reference. Find the System.Web.dll file, then double-click it, then click OK.

I have an Combobox at the right bottom edge of the form
I want that the combo box should not drop down
means when I click on combo box it displays the content only within the form not outside the form
So that if there is no space at Right bottom edge of the form it opens the items at above the combo box
Thax in advance

I assume when you are saying combobox you are refering to windows forms and not webforms. This is what you need to do.
change the the combobox MaxDropItems property to your needs.

I am encountering ExecutionEngineException and Null ReferenceException errors when opening a new form immediately after closing another form. The new form appears not to have enough memory to open. I have tried using Dispose on the closing form, but it has not helped. Anyone have any suggestions?
|
|

|

This shouldn't be a problem with just a form object. I would think that it is because of a component or some other code behind that form. Forms themselves really don't take that much memory.
Are you using ShowDialog to show forms? Are you calling Dispose on anny form that you use ShowDialog to show? If not, you're actually not releasing these forms and they are taking up memory and, more importantly, handles. If you run the system handle pool into the ground, you can get memory errors.

Hi,
I have a VB6 application which can raise events in other Windows app's via an ActiveX exe (Similiar to the coffeewatch components in VB6).
I have a requirement to link the application to a Unix based application. Is there a way of raising events in Unix based applications from Windows?
Thanks,
Lee.

There's no direct way of raising events on the Unix side from Windows. You'll have to write a component on the Unix side that listens to an IP port to receive events from the windows side, kind of client-server setup. How you integrate this into your project is up to you.

Is it possible to make a checkbox property read only?
There is no property for read only for a checkbox.
|
|
|
|
|
What is the purpose is making it read only?
You can make it disabled - Checkbox.Enabled = False.
You might want to consider using a different control in order to get the control that you desire or create your own custom checkbox but that is another story entirely.

I actually came across a problem just like this in my Advanced Programming using visual Basic Class. The problem required us to use check box's as a form of displaying information. (I.E. Does this room have a fireplace [x]checked) So there is use for a read only check box in this sense.
