Hi,
I have placed a list View control & a Tree List View (Custom control obtained from this site for placing the tree & list view together) one below the other for a specific requirement in my application. Now I need to synchronize the Horizontal scroll for both these controls.
Any idea on how to do this is most welcome.
Thanks!

hi,
I've a problem in my soap based application. There are some dll files which were downloaded and added in my dll list. Now the problem is there's an error popping out which is related to the security. i even gave FullTrust to the downloaded dll files and still the problem persists.Since the dll file is not accessed theres a problem in database connectivity.The Connection status is alwalys closed and im not able to Open it.
The Full Trust for the files were given using .Net Configuration 1.1 and even caspol was used.
if anyone has got the solution then do send me the reply.

All yuo have to do is search the articles for "wake on lan" and you'll find these[^].

I need to send a signal from one instance of my application to another. What would be the best method to do this?
In Win32 I would use a named event and have a listening thread to pick up when that event gets signalled. But named events dont seem to be available in .NET 1.1

WM_COPYDATA is the easiest way to do this. Yes, you need to impliment this yourself, I don't think C# has a method that calls it.

You could use remoting for this.
There's a good example on single instance applications on MSDN: Real World Applications Sample, Part 1[^]
There are a few little bugs in there and it's written for .NET 1.0 IIRC (so some channel security settings have to be changed for 1.1), but altogether it's working nicely.

Do you mean as a web app ? No.

If it's C#, it will work where-ever you can install the .NET framework.

You can't install it on a web server. You can install it on any version of Windows that supports .NET, and you can make the installer downloadable from a website, then the user has to run it locally.

i would to create a file in a temporary volume and with read/write access for my application only.

You can't. The best you can do is make it hidden, so most people when they browse the file system won't see it.

Look at the System.IO.IsolatedStorage namespace, and see if it offers what you want.

I'm stuck trying to parse the date out of an RSS 2.0 feed. According to the RSS specification the date has to be in this format:
Sat, 07 Sep 2002 00:00:01 GMT
I have tried using DateTime.Parse with no success, and I'm not really having luck with DateTime.ParseExact. I'm not looking for an answer neccesarily but someone to point me to the right direction.

 Maybe it would help if I was parsing the right node. I don't think parsing the GUID node as datetime will work

Hi,
my problem is that i have a business layer which contains all my classes that represent my entire "world" (i'm writing a app for the registration of the members of our organization so this business layer contains classes like Member, Membership, MembershipPayment etc.)
the problem no is that these classes do not really fit the databasetables in my database (SQL Server) i mean, a class not always has as many properties as a table has columns and there is no table for each kind of class.
my problem no is, how do i connect my business layer to the DataTables and DataSets of my Data Access Layer? can someone give me a concrete example?

In my main program i create a thread to run a function which is infinite (while (true))
when i close the main frame of the program the thread is still running
how can i make it collected by the gc automaticly when the main frame closes??
Thanks

thread.IsBackground = true; will cause the thread to be aborted when the application is closed.

Hi there,
I've got the following problem:
I create a panel in an empty Form. then I set this panel to dock to the left.
Inside that panel i add some buttons, all docked to the top.
I set the autoscroll property on true.
When i start the app, i resize my form so the vertical-scrollbar automatically appears.
Now the problem:
When i start 'dragging' the scrollbar up and down, on SOME pc's the contents of the panel won't change position until i release the scrollbar. On my pc it will update directly, so i see the contents sliding smooth, but on a lot of other pc's it won't slide, until i stop scrolling.
I hope somebody has the answer for me 
Greetz,
Pete

I found the solution:
it was indeed a windows display setting.
This setting is found here:
1. Right click an empty area of your desktop.
2. Select Appearance
3. Select the Effects button
4. Place a checkmark in the "Show window contents while dragging" checkbox to enable this setting.
when you restart the application it works.
