How to get information about softwares installed on Windows Mobile devices?

Best method is to ask the configuration service provider (CSP).

Step 1: Add Reference to Microsoft.WindowsMobile.Configuration
Step 2: Add the following statements at the top of the c# code file.

using System.Xml;
using Microsoft.WindowsMobile.Configuration;

Step 3: Prepare a csp string (xml format) and pass it to ProcessConfiguration method of ConfigurationManager. Return value is the xml string which contains all currently installed softwares on the device.

private void ListInstalledSoftwares()
{
string cspString = “<wap-provisioningdoc><characteristic-query type=”UnInstall”></characteristic-query></wap-provisioningdoc>”;
XmlDocument xmlResult = null;

// Use CSP to get list of installed applications
try
{
XmlDocument configDoc = new XmlDocument();
configDoc.LoadXml(cspString);
xmlResult = ConfigurationManager.ProcessConfiguration(configDoc, false);
Debug.WriteLine(xmlResult.InnerXml);
}
catch (Exception ex)
{
Debug.WriteLine(“Failed to get list of installed applications. CSP failure. [Exception: ” + ex.Message + “]”);
}
}
