Hi,
I'm currently using flowcentric and need to connect to SQL2005, I have tried all the examples in the manual that I have for flowcentric, but none of the are working.
Flowcentric uses vbscript (It's the first time I use vbscript), anyone that can give me a few pointers or an article or whatever there is for more info on this
Thanks in advance

Is there some reason why you're not asking Flowcentric this question?

You'll have to be more specific. What kind of hardware?

I have no clue what you're really getting at, so I'll take a guess as to what you mean:
You're trying to bind a set of 1,000,000+ records to a ListView. The solution is simple. Don't. Why would the user want to scroll through that many records?? Use some kind of filtering on the data to reduce the number of records returned or some other method of organizing the data. There's just no way any user is going to put up with a control containing that many records.

I want to Get the IP address of my machine using the Windows API in .NET(Windows Application).
Api's should support Ipv4 and Ipv6 format.

How To Get IP Address Of A Machine[^]
I don't think there are separate ways for ipv4 and ipv6. If the computer has ipv4, you'll get an ipv4 address. If ipv6 is enabled, you'll get an ipv6 address (::1).

hi
when i am running my windows application in vb.net .i am getting an error
as below
The CLR has been unable to transition from COM context 0x1a1298 to COM context 0x1a1408 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
please suggest any solution to above problem.its very urgent
thanks and regards

Press CTRL+ALT+E - opens the exceptions window. Goto Managed Debugging Assistants. I *think* you want to uncheck the ConextSwitchdeadlock checkbox.
If not, logically determine which one is appropriate.
Cheers!
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Not enough information to go on. What COM components are you using in your app?? It would appear that one of them is not working correctly or, maybe, is running as an MTA when VB.NET expects to run as an STA by default.

Sometimes you maybe doing a call to an object that does a large amount of processing and takes longer than 60 seconds. The exception assistant assumes that the operation is a deadlock or is unresponsive and will throw the error.
Just something I ran into before.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

When I am Opening my appliaction from .exe, If a dll is missing it throw me an error :
An error occurred creating the form. See Exception.InnerException for details. The error is: Could not load file or assembly 'nsoftware.IPWorksSSL, Version=8.0.3022.0, Culture=neutral, PublicKeyToken=cdc168f89cffe9cf' or one of its dependencies. The system cannot find the file specified.
How Can I Check at start of the Application.
Or How can It Attached with my application

When you build your deployment project make sure the DLL is included or make it copylcal = true if you are using clcikonce.

Yes, It is Understand.
but after installation if someone deleted the .dll files from client machine then the problem arise

That's too bad. They'll have to reinstall your software.

Then its their own fault. Even if you check at start up all you will be able to do is tell them there is a missing dll, so what is the benefit?

Hello,
Is it possible to user the authentification control provided by Aspx in a winform application ?
Thanks

Sure - you just need to deploy your page to a website, and put a web control in your winforms app.
