Hi:
I would like to incorporate into my project a wizard for connecting to Virtual Private Network (VPN). In other words, I would like to write my own Microsoft Connection Manager.
Any thoughts on where I can start and where to get the info?
Thanks

I know this is probably a stupid question, but I just started on this whole VB thing (damn that .NET! Else I wouldn't be learning VB...). So far I've written a program to type a message in one textbox that displays in another textbox as encrypted text, and now I want to add an option to save the encrypted text. Help, anyone?

As I have created one application using Visual Basic.NET, I found out that the application pop-up very slow. I don't know why?
Please help? Thanks!

Check to see if you're compiling in debug mode. I've found that compiling in release mode with optimizations on can decrease initial load time up to 10x.

there is also a known bug in this verson of the dotnet framework involving slow start times.
If you don't have one... try adding an "ASPNET" account to your machine. you can disable the account if you want... it just needs to be there.

Have a look at the ngen.exe util that comes with the .NET Fx.
You should get an immediate benefit.

Hi all!
I made a simple Windows Application (MyApp.exe) that shows a simple form with the system date.
That application adds an icon to the system tray (a notify icon) that has associated to it a simple context Menu (Exit). So far no problems...
My problem is:
If i run MyApp.exe 2,3,4 or n times it adds 2,3,4,n icons to the system tray
 
How can i prevent this in order to if i had already the icon of MyApp in the system tray, and if i click on MyApp.exe the focus goes to the form of MyApp and don't add a new icon to system tray??
Thanx in advance

You just check if your app allready is running with eg. ::FindWindow(...) (you need to P/Invoke it)

Rather than using the FindWindow API, there is a nice .NET way to find out if your app is already running.
If UBound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName)) > 0 Then
If this returns true then there is another instance of the process running. What I haven't had time to work out yet is how to activate that existing instance. So if anyone knows off the top of their head how to do that, please comment. I've done plenty of this stuff with API calls in VB6 but I'd prefer to use native .NET as much as possible now.

In *VB* ??? There are toolkits to do it in C++, but I don't think they exist in VB. They are also commercial products and they are not cheap.

Half the reason people switch away from VB is to find out what actually goes on.. and then like me they find out that they weren't quite as good as they thought - they've been nannied. - Alex, 13 June 2002

I want to add in the standard help file for my VB application. Any VB6.0 built-in tools can be used for this purpose? If not, any alternative can I choose?
Thanks

Yup. If I'm not mistaken, this also allows you to create context-sensitive help per function. Pretty useful.

Also, you can get the HTML Help Workshop from mimcrosoft.com to make a .chm. It's free, just search for it.

How could i use escape sequences in VB to write strings like this: 'a1 "b1" c1' - where ' is a substitute for " ?
rechi

|

|

Heya,
" is escaped by "" (ie double 'em).
/WW

In VB you could use two double quotes back-to-back...
"a1 ""b1"" c1"
...or use the actual ASCII/ANSI char itself...
"a1 " & Chr(34) & "b1" & Chr(34) & " c1"
I prefer the first method.

I have a form and I want to make it so only one instance of that form is opened. I can do this with a counter variable in my form class so when it is loaded it incremenets and if they go to file->exit it decriments. But if thye hit the X button in the upper right, the form is closed and my counter vraiable stays at one. I need a way to make it so however they close it my counter is updated accordingly.

I would suggest that you use the Singleton pattern instead of tracking counters.
