Getting a list of installed programs on windows using C#

[Paul Horn]

Hi

I need some help here. I would appreciate it if any one can help me. My
2 questions is this:

1. How do you get a list of installed applications on Windows?
2. How do I get a program's description from a exe?
(Example - sqlservr.exe = Microsoft SQL Server 2000)

I am using C# with Visual Studio .net 2003. Thanks in advance...

While not exactly programmatic, I’d suggest looking into Belarc Advisor
(http://www.belarc.com/free_download.html).

Try,
Microsoft.Win32 .RegistryKey subKey1 =
regKey.OpenSubK ey("SOFTWARE\\M icrosoft\\Windo ws\\CurrentVers ion\\Uninstall" );
string[] subKeyNames = subKey1.GetSubK eyNames();

foreach (string subKeyName in subKeyNames)
{
Microsoft.Win32 .RegistryKey subKey2 = subKey1.OpenSub Key(subKeyName) ;

if (ValueNameExist s(subKey2.GetVa lueNames(), "DisplayNam e") &&
ValueNameExists (subKey2.GetVal ueNames(), "DisplayVersion "))
{
listViewApps.It ems.Add(new ListViewItem(ne w string[]{
subKey2.GetValu e("DisplayName" ).ToString(),
subKey2.GetValu e("DisplayVersi on").ToString () }));
}

subKey2.Close() ;
}

subKey1.Close() ;

and...

private bool ValueNameExists (string[] valueNames, string valueName)
{
foreach (string s in valueNames)
{
if (s.ToLower() == valueName.ToLow er()) return true;
}

return false;
}

Phil.

Forgot about the file description.

Try,

System.Diagnost ics.FileVersion Info fileVersionInfo =
System.Diagnost ics.FileVersion Info.GetVersion Info(fileName);
string fileDescription = fileVersionInfo .FileDescriptio n;

Phil.

Forgot to add this line at the beginning

Microsoft.Win32 .RegistryKey regKey = Microsoft.Win32 .Registry.Local Machine;
