Reading from / Savign to the Registry

Boblysan

Good afternoon, I am looking for any reference information you may be able to point me to regarding reading app configuration information from the registry / writing information to the registry. Basically, I have an application which I would like to read from a configuration section upon launch. Also, is there a simple way to play a wave file in a C# application? I have been looking in to the DirectX stuff but my current application does not require this level of coding. I'm just looking for an easy way to simply play a wave file. If you can direct me to some reference material, it would be very much appreciated. Thank you all. Bob

Hi Buddy This is an example how to read and write to registry. Hope that will be helpful to u //sub key is the registry key public static string getRegValue(string subKey) { string strVal=""; RegistryKey key =Registry.LocalMachine.OpenSubKey("SOFTWARE\\mysoft"); if (key != null) { strVal = key.GetValue(subKey).ToString(); } return strVal; } //subkey is the name of the ley and val is the value that will be set public static void setRegValue(string subKey,string val) { try { RegistryKey key = Registry.LocalMachine.CreateSubKey("SOFTWARE\\mysoft"); if (key != null) { key.SetValue(subKey,val); } } catch(Exception ex) { Console.WriteLine(ex.ToString()); } }

The easiest reference is all you need. Open the Visual Studio help (or surf to msdn.microsoft.com) and open the .NET SDK help. See Registry class. From the help, here's a C# example of getting the root key HKEY_LOCAL_MACHINE: RegistryKey rk = Registry.LocalMachine; See also the RegistryKey class. Its obvious members are: CreateSubKey() DeleteSubKey() DeleteSubKeyTree() DeleteValue() GetSubKeyNames() GetValue() GetValueNames() OpenSubKey() SetValue() Close() SubKeyCount (Property) ValueCount (Property) Namespace is Microsoft.Win32.RegistryKey
