Take a look at the Hashset< string>. It should work at an acceptable pace for this requirement (and I'd like to know if it doesn't). Just load it in from a file when you start your app, and use .Contains(...).

If it weren't for my elderly PC setup I'd give this a go, but I'm running with Win2K Pro which means I cannot install .NET 3.5. But I think you've pointed me in the right direction regards implementation - a hash table looks a good approach to explore. Thanks. And I suppose one of these days I'd better stump up some cash and upgrade my PC?!

Do you have 2.0? Iesi.Collections contains a HashedSet< T> which is functionally very similar.

.NET 2.0 SP1 ... but no Iesi. Is Iesi a 3rd party library I need to install? And if so can you suggest a reliable source please.

Aha! ... NHibernate.org - is that it?

Yup the NHibernate chaps maintain Iesi iirc. Nhibernate distro, or even grab their source.

Are we talking NHibernate 2.0.0.Beta1 here? I can't see a release-version binary. I'd prefer to only download the binary ... is this Beta pretty stable do you know?

OK - I can see my mistake. I followed the Download link in the left-hand menu, rather then the direct link right in front of me. The download link doesn't show the release version!

Any of the above. Iesi is pretty stable, I doubt its changed much since the initial release. Diamond Binding has a known good version in the release (as we use NHibernate). Link in sig.

Sorry, one more question. Now I've downloaded it - how do I install it?!

Marquee Progress Bar with Start & Stop

27-Jan-09 2:47

DB you can just install, the assembly will be in here Program Files\D&C\DB\Runtime\Assembly and in the GAC. I'm not sure where NHibernate puts things off the top of my head.

If you've run an NH installer, then I guess check the GAC and the NH install directory. Its a pain to get stuff out the GAC as well - and VS doesn't enumerate the GAC for references which is quite annoying.

I think Iesi.Collections originated on code project.. yeah onenote tells me it came from here: http://www.codeproject.com/csharp/sets.asp#xx703510xx. Might be easier to grab the original. Smile | :)

Hi,

I am trying to implement a progress bar (derived from the standard Windows.Forms.ProgressBar) which allows you to set to Marquee mode and then start and stop the animation. I have solved most of the problems, but when I stop the animation by setting the MarqueeAnimationSpeed to zero, the blocks on the bar remain visible, which is not what I want.

The only other way I can think of to stop the animation is to change the style of the progress bar to not be Marquee and then put it back again when I want to start the animation. The problem here is that the animation does not restart.

I could override the OnPaint() and do my own animation but I am reluctant to do this because it would require some work to make the progress bar look like a standard progress bar, respecting all the property settings on the original Forms.ProgressBar.

There must be a way to get a Marquee to start and stop.

Any help or ideas to try would be very gratefully received.

Best wishes, Patrick

ListViewItem: ForeColor and BackColor are ignored while running in terminal session (Citrix)

Hi,

i have an application (fw 2.0) with a ListView in details mode. Some of the ListViewItems have different values for ForeColor and BackColor. Running the application local, all looks fine. The ListViewItems appear with the given values for BackColor and ForeColor. Problem: When i start the app by using a terminal session (Windows Server 2003 with Citrix) the BackColor and ForeColor attributes of the ListViewItems are ignored. What can I do? I don't want to override OnDrawItem, OnDrawColumnHeader and OnDrawSubItems to solve this problem.

Thanks for any hint.

Set a breakpoint at the start of this method, and then step through it keeping a careful eye out on which statement you are on, and what the value of the variables are. When it hits the exception - you'll know what caused it.

Hi,

a few decades ago people invented line numbers for easily pinpointing a problem, hence:
- tell your IDE to always show line numbers in the editor windows (Visual Studio, see Tools/Options menu)
- always look at Exception.ToString() and not just Exception.Message

Taken together you will know right away what line bombs, chances are you will immediately know why too.

is it possible to stop the flow of the project?

i get error and it is catched in try catch block...

after that i don't want to continue...

i want transfer the flow to my starting page...

how can i do this...

If it's a method you add for example return the the end of the catch block if there are statements outside the try-chatch structure. However, finally portion will still be executed. Then on the calling side you must handle this situation so that you don't continue there and so on.

this connection coding function is called in remaining forms...

22-Jan-09 23:26

Can you post the code? It doesn't matter what you do in the code, but it's important that you model the flow so that methods exit nicely and the calling method understands not to continue with execution. But as said, it's a bit hard to say more without the code.

Okay, you could use for example bools:

public bool mthOpenConnection()
{
   try
   {
      string[] datasource = File.ReadAllLines("d:\\k2.txt");
      if (datasource[0] != "")
      {
         objprop.connection = "Data Source=" + datasource[0] + ";Initial Catalog=Inventory_VS;User ID=sa;Password=sa";
         objCon = new SqlConnection(objprop.connection);
         if (objCon.State != ConnectionState.Open)
         {
            objCon.Open();
         }
      }
   }
   catch
   {
      MessageBox.Show("ENTER CORRECT DATA SOURCE NAME IN UR TEXT FILE");
      return false;
   }
   return true;
}

and then

public DataSet mthGetLogin(Properties objproperties)
{
   if (!objDBconnection.mthOpenConnection()) 
   {
      return null;
   }
   SqlDataAdapter objDALogin = new SqlDataAdapter("sp_login", objDBconnection.objCon);
   objDALogin.SelectCommand.Parameters.Add(new SqlParameter("@uname", objproperties.Username));
   objDALogin.SelectCommand.Parameters.Add(new SqlParameter("@pword", objproperties.Password));
   objDALogin.SelectCommand.CommandType = CommandType.StoredProcedure;
   objDALogin.Fill(objDSLogin);
   return objDSLogin;
}
