I got as far as Step #4
When I view the custom actions, there are four folders there; Install, Commit, Rollback, and Uninstall as well as the top node "Custom Actions". Right clicking on anyone of those items brings up a box and I have four additional folders to choose from, I have to select one of the folders in order to enable the "add output" button ...

Question, which folder do I select in the pop-up box, and wich node while viewing the custom actions do I select or do I select the top node "Custom Actions"?

I think I going to create an article for others after all this ... LOL

Actually you should right click on any node => Add custom action. Then follow the rest of the steps.

Ive created the Install() file and I must have missed something, here is my code ...

namespace ScreenSaver1
{
    [RunInstaller(true)]
    class Installer1 : Installer
    {
        const string _screenSaverValue = "SCRNSAVE.EXE";
                
        public Installer1()
        {
            //Default constructor
        }
        
        //override the Install method ...
        public override void Install(System.Collections.IDictionary stateSaver) 
        {
            base.Install(stateSaver);
           
            RegistryKey theRootKey = Registry.CurrentUser;
            RegistryKey theControlPanel = theRootKey.OpenSubKey("Control Panel");
            RegistryKey theDeskTopKey = theControlPanel.OpenSubKey("Desktop");

            if (theDeskTopKey.GetValue(_screenSaverValue) == null)
            {
                //Add some values
                string valName = _screenSaverValue;
                object testValue = Directory.GetParent(Environment.SpecialFolder.System.ToString()) + "ScreenSaver1.scr";
                RegistryValueKind valKind = RegistryValueKind.String;

                theRootKey.SetValue(valName, testValue, valKind);
            }
            
        }

    }
}

Everything else works fine, just not setting the registry value ...

It's one simple mistake -you can post it in the subtle bugs forum BTW Smile | :)

-. You've written

theRootKey.SetValue(valName, testValue, valKind);

... while it should have been

theDeskTopKey.SetValue(valName, testValue, valKind);

as the value is under the "HKEY_CURRENT_USER\Control Panel\Desktop" key not the "Current User" root key.
I hope it works.

PS.
the line

if (theDeskTopKey.GetValue(_screenSaverValue) == null)

tests only if the user doesn't have any screen saver chosen. If they have another screen saver chosen this value will not be null. Rather it will be the path to the other screen saver. You should always SetValue() even if it wasn't null.

I've made the changes and still I have nothing ... it won't create the value within the Key ... everything else works though.

To bad I can't just send you the entire project to look at ...

Thanks for all your help, you've definately went further to help me than I ever anticipated. I really appreciate your help! I've learned several things from this, thus far ... Smile | :)

Exporting DataGrid to Excel

I am searching for the code to export the datagrid columns in to the excel sheet. Most of the code i have seen are reading the each value one by one from the datagrid or dataset and writing in to excel sheet. But in Asp.net, there is an easy way to do it. Is there is any easy way to do in windows application also. Thanks to all.

You can export your data as Xml files, or comma delimited files which are easily read by Excel among other programs as well.

You can use a Path object from the Sytem.IO namespace.

string fileName = Path.GetFileName(OpenFileDialog1.FileName);

Path.GetFileName[^]
FileDialog.FileName[^]

hi,
use Substring and LastIndexOf functions to get the required value;
any string supports these methods.

I am looking to work with LCS APIs like RTC Client API. I am unable to find this RTC Client API. Can you help me in this regard?

Actually the situation is like this:
I have some users in my Active Directory and I want to develop some client application which will display all the users in the Active directory using the Live Communication Server APIs like RTC Client API.

What API? If it's WinAPI, you may want to take a look at this site:

if you have C/C++ signatures to call the API by there's a tool available called "pinvoke wizard" that will generate the pinvoke signatures for use in .net. If you don't have any API documentation first and foremost, it sucks to be you! All I can suggest in that case is to visit the c++ forums and ask for help in reverse engineering the API from the dll files.
