Hello,
I have three forms: frmCustomerTemplate, frmAddCustomer, and frmUpdateCustomer.
frmAddCustomer derives from frmCustomerTemplate, and frmUpdateCustomer derives from frmAddCustomer.
Diagram:
frmCustomerTemplate --> frmAddCustomer --> frmUpdateCustomer
I'm encoutering a problem where frmUpdateCustomer is not getting values from the fields that were defined on frmCustomerTemplate. For example, frmAddCustomer defines a Home Telephone textbox that was not declared on frmCustomerTemplate. When I do an update (using frmUpdateCustomer) I can only get the value from the Home Telephone textbox. All the other fields populate my variables with nulls, even though they are populated. All the controls on frmCustomerTemplate are declared as Protected.
Any ideas why this is happening?
Thanks,
Andrew

I have an application that calls a webservice and passes
a file to it to process the data. I currently have 1 file
format, and can process the data with no problems.
I would like to create a client that calls a webservice
dependant on the file name.
My question in short is this. Can you dynamically create
a reference to a webservice at runtime?
I assume I will need to modify the client to create a
proxy on the fly depending on file name but not sure if it
is possible.
Thanks in advance

How do I make a mdiChild forms dock to a parent and auto hide to look like a tool bar (ex. VS.net property window)?

It depends how far you wany to go.
Take a look at the following article. It demonstrates how to popup a graphic. You should be able to adopt a similar technique with any form.

I had the idea to copy the controls of a panel to a new Form. It works if I use the copyTo method of the control collection of the panel.
The problem is, the controls aren't copied, there moved!? Is this a bug or ...? Anyone an idea?
Test it yourself. On a simple Windows Form with a panel1, a button1 and a textbox1:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' rise!
Dim form2 As New Form
Dim c(Panel1.Controls.Count - 1) As Control
Panel1.Controls.CopyTo(c, 0)
form2.Controls.AddRange(c)
form2.Size = Panel1.Size
form2.Show()
End Sub
As you will see, the controls are moved to the new form2, instead of copied there.

That's because you're only copying the references to the controls, not the actual controls.

Here is the problem I'm having and maybe some VB6 guru may answer and resolve my problem.
I have WinForm Control created in .NET as an ActiveX control and purfectly registered on the system.
It works fine in any container I have: TstCon32, MFC Dialogs, all Office Applications and etc.
Actually, it works fine even inside VB6 when in Design Mode. When I'm running in VB6 Run/Start(F5) or Start with Full Compile (Ctrl+F5) -- it also works fine. So, I'm assuming that everything is fine with my control.
However, when I'm trying to create Project.exe through File/Make Project.exe VB6 starts compiling the program and when about 10% Progress is shown I'm getting an error message box: "Unexpected error".
So, what could be wrong? And how could I find this out?
Thanx

Add a reference to the CDO com object and use CDO calls to exchange server.
There are several varieties of CDO calls so pick the one that suits your needs.

Hi,
I wanted to know if DataSet can be used as a Data Structure in Visual Basic.NET

I am near the end of a program. This program accesses rich text files and jpeg files using the app path method. This works well while the program is contained within the same folder as the files.
I want to have the compiled program in "program files" and have the program access the rt files and jp files from the cd rom no matter what drive letter is assigned to the rom.

I think you want to know which one is the CD-ROM drive :
use these APIs:
FindFirstVolume<br />
FindNextVolume to search volumes
and
GetVolumeInformation
to check file system..

after searching high and low i am unable to find anything in .net or 3rd parties for converting rtf or any text to postscript.
is there any classes in the .net framework that allows this to happen dynamically? i have an rtf interface application written in vb.net that i want to write out to postscript.
can anyone point me in a direction that will that the rtf to postscript?

I'm trying to load an image file from a web server. The request simply fetches a file from an HTTP location that I know exists (it loads in IE).
However, when I run the program I get the following:
System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.
I don't know of any changes to our ISA server, but I have SP4. Does anyone know how to fix this?

If I have an application that uses the FromFile("Pathname") method, how can that code recognize where to find that file on another computer.
For example, if I want to display a picture that I'm developing on my computer and I use the FromFile("C:\my Bitmaps\Pic.bmp") that's all fine and dandy.
But if I were to install that application on another computer, and when deployed, generically dumps every dependent file into "C:\Program Files\WindowsApplication1", the path I originally gave to find the Bitmap "C:\my Bitmaps\Pic.bmp" will no longer be valid.
How can I make it so that when the application is installed on another computer, all the paths will be correct?
Thank you

I am not sure I understood your question correcty, but:
1. If the user wants to open an arbitrary picture on your program, you can use the OpenFileDialog class to get the path and then use that path on Bitmap.FromFile() method.
2. If you are talking about  a picture that you want to distribute with your program, install it in the same directory as your executable and use something like Application.StartupPath + "\pic.bmp" or embbed it in the executable.

I think the second option is the one I was looking for.
Let's say under the Form_Load event, I want the form to open up with a picture. On my computer, the picture is located at C:\my pics\Pic.bmp, but if I were to install this program at on another person's computer, it would install at the default location C:\Program Files\WindowsApplication1\Pic.bmp, and when he would try to run the program, it would not find the picture because my code is looking for C:\my pics\Pic.bmp, not the other path.
So instead of using BitMap.Fromfile("Path") just use Application.StartupPath & "\Pic.bmp" ?
Also, how could I embed a picture or a WAV into the executable?
thanks
