This is the de facto way of marshaling and transmitting data between two different AppDomains. See Accessing Objects in Other Application Domains Using .NET Remoting[^] for topics and examples. Also visit http://www.ingorammer.com[^] for arguably one of the best sources for .NET Remoting information. He also has a book. And speaking of books, there's also Microsoft .NET Remoting[^] from the Microsoft Press. It's a good intro and intermediate book on .NET Remoting. You can also search the CodeProject site for information on .NET Remoting as well.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

I am trying to implement a system which locks the user out from all Windows functions such a the 'Start Menu', shortsuts such as CTRL-E and CTRL-ALT-DEL. Basically I have designed a database for the public to search for emigrant records from the 19th Century between Europe and US. But as with all things I am getting 'fiddlers' who seem more interested in trying to mess up Windows settings. So what I need to do is have a splash screen which will display the shortcut or link to the database and nothing else. The program will then lock out any attempt to access any other Windows functions. Is this sort of functionality available in C# and if so does anyone have any suggestions, Regards, John Re: Lockdown PC Christian Graus27-Jan-04 15:32 Christian Graus 27-Jan-04 15:32  You're using the wrong language - you need to set up some system hooks, which I believe requires C++, although it may be possible using some sort of funky interop stuff.

This is by design. One can hook Ctrl+Tab and similar key combos.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: Lockdown PC johnstacey28-Jan-04 2:01 johnstacey 28-Jan-04 2:01  Is there anyway of blocking or diabling the CTRL-ALT-DEL option then in windows using C# or anything that can run with C# as shutting down my app will allow them back in to mess around with the settings and unfortunately defeats the purpose of doing it Any ideas?

Custom Controls Victor Boctor27-Jan-04 14:33 Victor Boctor 27-Jan-04 14:33  Hi, I am implementing a custom control which has a listview as one of its sub controls. I am able to populate this list at design time through the control properties. The populated list then appears as expected in design time. Once I run the application, the list appears empty. Terminating the application and re-opening the form (in design time), shows the list as empty! How can I retain the values of the properties provided by the user at design/runtime!??!!

For example, if you have a form with two edit boxes, the first is set to TextBox1 and the second is set to TextBox2. I am sure these design time values will not be saved to files, however, they will be part of the form or something.

A preferd item to store the values is an ArrayList or something like that. On cration of your sub application you could write something like (in Main) MyListViewLib.MyListView myListView = new MyListViewLib.MyListView(myArrayList) (in Sub(a constructor)) MyListView(ArrayList anArrayList) { for(int i = 0; i < anArrayList.Count; i++) { theNewListView.Add(anArrayList[i]) } or something like this... If you close all your applications then you have to save it to a file.

Change Color of CheckedListBox's Item hxxbin27-Jan-04 9:52 hxxbin 27-Jan-04 9:52  Hi I'm trying to do a batch manager, and I use a CheckedListBox to display the status of the jobs, but I want to change the color of every item, there is a way to do it??? Thanks ---- hxxbin Re: Change Color of CheckedListBox's Item Heath Stewart27-Jan-04 11:36 Heath Stewart 27-Jan-04 11:36  Extend the CheckedListBox control and override OnDrawItem. In the DrawItemEventArgs passed to the method (and don't forget to call base.OnDrawItem when done), set the DrawItemEventArgs.BackColor to a color based on the checked state of the item (which you can get the index for in DrawItemEventArgs.Index).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: Remove/hide scrollbar in listbox Mazdak27-Jan-04 9:22 Mazdak 27-Jan-04 9:22  You mean ScrollAlwaysVisible property ? Mazy No sig. available now. Re: Remove/hide scrollbar in listbox Fleischen27-Jan-04 9:39 Fleischen 27-Jan-04 9:39  no, that property does not remove the scrollbar. I never want to see the vertical scrollbar, even when i have allot of elements.
