Get a list of installed programs with application icons
I need to get a list of installed program on local machine with application icons. Below is the code snippet that am using to get the list of installed program and installed directory path.
/// <summary>
/// Gets a list of installed software and, if known, the software's install path.
/// </summary>
/// <returns></returns>
private string Getinstalledsoftware()
{
//Declare the string to hold the list:
string Software = null;
//The registry key:
string SoftwareKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(SoftwareKey))
{
//Let's go through the registry keys and get the info we need:
foreach (string skName in rk.GetSubKeyNames())
{
using (RegistryKey sk = rk.OpenSubKey(skName))
{
try
{
//If the key has value, continue, if not, skip it:
if (!(sk.GetValue("DisplayName") == null))
{
//Is the install location known?
if (sk.GetValue("InstallLocation") == null)
Software += sk.GetValue("DisplayName") + " - Install path not known\n"; //Nope, not here.

Software += sk.GetValue("DisplayName") + " - " + sk.GetValue("InstallLocation") + "\n"; //Yes, here it is...
}
}
catch (Exception ex)
{
//No, that exception is not getting away... :P
}
}
}
}
return Software;
}
Now the issue is how i can get the installed application icon ?
Thanks in advance.
To determine if its an update, there will be a key called IsMinorUpgrade
. This is present and set to a 1
for updates. If it's 0
or not present, then it's not an update.
To get an icon from an executable, use this code:
VB:
Public Function IconFromFilePath(filePath As String) As Icon
Dim result As Icon = Nothing
Try
result = Icon.ExtractAssociatedIcon(filePath)
Catch ''# swallow and return nothing. You could supply a default Icon here as well
End Try
Return result
End Function
C#:
public Icon IconFromFilePath(string filePath)
{
Icon result = null;
try {
result = Icon.ExtractAssociatedIcon(filePath);
} catch { }
return result;
}
To extract icon of installed windows application first we need to figure out the location of icon for the installed windows application. This information is stored in registry at following locations -
- Key name - HEKY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall Value - DisplayIcon
- Key name - HKEY_CLASSES_ROOT\Installer\Products{productID} Value - ProductIcon
