Register Class CSharp

How to use it

• In Visual Studio Add "RegisterClass.cs" in Solution Explorer.
• Add

using m4.RegisterClass;

and

RegClass Reg = new RegClass();

that all.

Examples

Wite

Wite String (REG_SZ)

Reg.WriteString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Name", "Odyn");

(string, string, string, string)

Wite Int32 (REG_DWORD)

Reg.WriteDWord("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number32", 2);

(string, string, string, int)

Wite Int64 (REG_QWORD)

Reg.WriteQWord("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number64", 2);

(string, string, string, long)

Wite Extendet String (REG_EXPAND_SZ)

Reg.WriteExString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Location", "c:\\Program Files\\My program");

(string, string, string, string)

Wite Multi String (REG_MULTI_SZ)

Reg.WriteMultiString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Setting",  new string[]{"bold", "52", "close"} );

(string, string, string, string[])

Wite Binary (REG_BINARY)

Reg.WriteBin("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Some data", new byte[] {10,10,10});

(string, string, string, byte[])

Read

Please note that the last value is default value.

Read String (REG_SZ) and Extendet String (REG_EXPAND_SZ)

MessageBox.Show("Version Name: " + Reg.ReadString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Name", null));

MessageBox.Show("Version Name: " + Reg.ReadString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Location", null));

Read Int32 (REG_DWORD)

MessageBox.Show("Version Number32: " + Reg.ReadInt("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number32", 0));

Read Int64 (REG_QWORD)

MessageBox.Show("Version Number64: " + Reg.ReadInt64("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number64", 0));

Read Multi String (REG_MULTI_SZ)

string[] Value = Reg.ReadMultiString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Setting", null);
            string Message = "";
            foreach (string value in Value)
            {
                Message = Message + value + " ";
            }
            MessageBox.Show("Setting: " + Message);

Read Binary (REG_BINARY)

byte[] ValueByte = Reg.ReadBinary("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Some data", null);
            string Suma = "";
            foreach (byte value in ValueByte)
            {
                Suma = Suma + value;
            }
            MessageBox.Show("Some data: " + Suma);

Delete

How to remove all the values that we created earlier

Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Name");
Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number32");
Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number64");
Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Location");
Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Setting");
Reg.DeleteValue("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Some data");

And the whole key

Reg.DeleteKey("HKEY_CURRENT_USER", "SOFTWARE\\My Program");

Error Handling

If you want to display errors simply turn on ViewError:

Reg.ViewError = true;

You can specify name for the window with error by changing ViewErrorTitle

Reg.ViewErrorTitle = "Register Operation Error";

This might be helpful in debug. You can change the window name for every operation.

Reg.ViewErrorTitle = "Write String Operation Error";
Reg.WriteString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Name", "Odyn");

Reg.ViewErrorTitle = "Write DWord Operation Error";
Reg.WriteDWord("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Number32", 2);

You can add you own error messages based on GetError status. true = error, false = no error (default).

Reg.WriteString("HKEY_CURRENT_USER", "SOFTWARE\\My Program", "Version Name", "Odyn");
if (Reg.GetError)
{
//Error appeared do what you want
}
