I wanted to see if there was an easy way to make this happen to assign any other value other than true or false. I guess I will have to start re-coding everything to use a diff value. Re: boolean variable as null Martin#27-Jul-07 9:14 Martin# 27-Jul-07 9:14  Hello, I think the only way to make it clear is to change the type to "int" could be easyly used as an enum also! Or if this is not possible for you, you have to add an additional bool value! All the best, Martin All the best, Martin Re: boolean variable as null Paul Conrad27-Jul-07 9:38 Paul Conrad 27-Jul-07 9:38  Take a look at Martin#'s suggestion. It sounded like to me you needed to populate the dropdowns, there's probably many ways to achieve what you are trying to do.

Anyhow, you need to make sure the three states somehow get stored in the DB too.

My website How do I display record when I click item in listbox c#.NET? bhopalite27-Jul-07 5:45 bhopalite 27-Jul-07 5:45  Here is what I have, I want to display in a new window or in the same form (on the right hand side) after a item in a listbox (which is located on the top-left side)is clicked. How do I go about doing this? Thanks. Re: How do I display record when I click item in listbox c#.NET? snorkie27-Jul-07 7:29 snorkie 27-Jul-07 7:29  Leverage the Click event for the list box. In the event code, you can grab the item selected, and act upon it. Use the ListBox.SelectedValue property to decide what was clicked. (assuming you limit your box to a single selection) Hogan Re: How do I display record when I click item in listbox c#.NET? Paul Conrad27-Jul-07 8:24 Paul Conrad 27-Jul-07 8:24  Like snorkie said, you have to have a button that on the click it goes to the new form and passes the selected value from the listbox to the new form. To prevent global variable ugliness, pass the selected value as a parameter in the constructor of the new form.

Everything was working fine until I referenced some classes from a separate dll. The proxy class generates fine and includes the classes from the separate dll. The problem is when the client calls the webservice with a calls that results in using classes from the separate dll the client throws an exception saying that I am using an object from an unreferenced dll. How to you reference this dll to make the client happy? Re: Web service question Drehmer28-Jul-07 10:21 Drehmer 28-Jul-07 10:21  Your client is probably receiving the message error from the server. So, I believe the solution is not in changing the client. Try to copy the DLL to the BIN folder in your WebService and see if it works. Charles. Re: Web service question Steve Messer28-Jul-07 10:28 Steve Messer 28-Jul-07 10:28  Thanks for your reply. It turns out that the problem was related to two different sets of similar classes. The code was using some objects from one set of classes and some from the other. The generated proxy code was all messed up thus confusing the client. Once we removed the duplicate (proof of concept) set of classes everything worked as expected. Methods FTP.ListDirectory doesn't list all files jpm.mendy27-Jul-07 4:48 jpm.mendy 27-Jul-07 4:48  Hello, I'm having a trouble with the 2.0 Framework method FTP.ListDirectory. I'm writing an application which creates a file by executing an http command, then verify if the file exists on the server and downloads it. The problem is that the list of files returned by Ftp.ListDirectory doesn't change even if the file is created(I can see it with a graphical FTP client). Sometimes it works and I get the list of all files. But it seems to me if I make many consecutive requests, the files list isn't refreshed any more as if it was stored in a cache.... Can you help me to fix it? Thanks. Re: Methods FTP.ListDirectory doesn't list all files Paul Conrad27-Jul-07 8:24 Paul Conrad 27-Jul-07 8:24  Are these files hidden or system files?

The directory listed by the code has only .zip files. I even can see them in my graphical FTP client. So my answer is no, files aren't hidden. Re: Methods FTP.ListDirectory doesn't list all files jpm.mendy1-Aug-07 6:14 jpm.mendy 1-Aug-07 6:14  Hi, I think the I have the answer to this post. I'm not really sure but so far I've done many consecutive tests and the results of the response always changes if new files are created. It's about the cache policy and this is the way to set it.

I am using the property "Bolded Dates" to add selected/some dates. But those dates are displayed in "BOLD". But I need to display with different background color (like selected). How can I display the "Bolded Dates" in different Background color? Thank you Ramesh Re: how to Change BoldDates Backgroud color in MonthCalendar control led mike27-Jul-07 6:08 led mike 27-Jul-07 6:08  Maybe the control does not support that. What does the documentation say? Is there an "owner draw" feature?

Is there any other control that can Matches my needs? Thank you.
