Sounds to me like you might have one of the following:
1 - A form that is hidden but not unloaded (there is a difference).
2 - An object variable that has not been set = to Nothing when you are done with it.

Ah, there is a form that is hidden (frmComSelect in the code below). But how do I close it? I have a hard time finding anything useful in MSDN.
The app is designed like this:
First a window is displayed prompting the user to make a selection.
Thereafter, the main window is displayed.
Private Sub Command1_Click()
If (optCom1(0).Value = True) Then
PortNum = 1
ElseIf (optCom1(1).Value = True) Then
PortNum = 2
ElseIf (optCom1(2).Value = True) Then
PortNum = 3
ElseIf (optCom1(3).Value = True) Then
PortNum = 4
End If
If (Adapter(0).Value = True) Then
PortType = 1
ElseIf (Adapter(1).Value = True) Then
PortType = 5
End If
frmComSelect.Hide
frmMain.Show
Main
End Sub
Cheers,
Fredrik

You would use frmComSelect.Unload

The compiler does not like that. It says 'Method or data member not found'
Do I have the wrong type of window?

Unload frmComSelect works fine. Thanks for the pointer.

Ok here is the setup. Myself and a few of my friends are new to .net but we all know c++ quite well and one person knows vb. I have created a class in c++ that I would like to inherit into a vb program so that vb can create and call functions in the class. I am under the impression that this can be done with cross language inheritance, but I can't find any information about it and I have no idea how to do it. Any information would be appreciated.
Thanks,

You can do that easily if you use the C++ managed extensions provided by .NET. Visit the resources here at CodeProject[^] for an introduction to Managed C++. For the most part, after you have a manged assembly it is only a matter of making a reference to it and deriving from it, regardless of the language you want to use.

Hello,
I have a VB dll which is invoked from VC client. VB dll is a COM component and it displays a form to input data.
The problem is that most of the times, whenever the user clicks the mouse outside the VB dialog, the from goes nehind the vc frame.
the VB form is loaded as modal still it happens.
Any suggestions.
Regards,
Deepti.

If you want it for the web, see your repeat post below and Chris's suggestion.
If it's for a Win32 client, consider using GDI+ and painting onto the form directly.

You mean in order to display it in a html page, i should save it as jpg.
If we go one step back, to making the graph it self.
How can I do that>?

2D bar graphs on an HTML page are easy...
1 - Create a table that has as columns rows as you need data columns.
2 - Create a gfew gif images that are 1 pixel high and as wide as you need the data column to be.
3 - Figure the biggest size you need to hold all your data and create your table to hold that size.
4 - Figure each of the other data points as a percentage of the highest value.
5 - Place each of the images into the table column, and set it's height equal to the percentage of that data point to the largest number.

I would like to clear few things for myself:
by table,, you mean an array?
gif image is an object that i can choose,, is that correst?

Let's back up a bit here...
What type of application are you writing?
Web app or Forms based app?
VB6 or VB.NET?
|
|
|
|
|
The application is VB
it is a forms based.
and its VB6
I basically have two arrays , one for X-axis and one for y-axis.
and all I would like to make a bar graph.

Hi,
My VB application makes a graph, I need to save the graph as a HTML file.
How can I do that?????
Thanks

Well, if you want to save it as a HTML file, you probably want to use SVG. If you want to display it in a HTML page, save it as a jpg.

hi
You can have your HTML content in a variable name sTemp. The insert this code where you want to create the HTML page. Here sTargetFolder is the path where the HTML files resides and concat test.html to that path. Then print that sTemp variable then close. Now check your folder.
Open sTargetFolder & "test.html" For Output As #1
Print #1, sTemp
Close #1
Hope this will help.
