//conn = new SqlConnection();
//conn.ConnectionString = _connectionString;
comm = _connection.CreateCommand();
//conn.Open();

comm.CommandText = storedProcedure;
comm.CommandType = CommandType.StoredProcedure;

foreach (MySqlParameter param in parameterArray)
{
comm.Parameters.Add(param);
}
outputParam.Direction = ParameterDirection.Output;
comm.Parameters.Add(parameterArray);
result = comm.ExecuteNonQuery();
result = int.Parse(outputParam.Value.ToString());

}
this line is Exception// catch (Exception ex)

You're trying to put an array of them in; you can't do that with Add.
You could use a foreach loop to add them; that also allows you to verify that they're not null and such.

List of classes and namespaces in .Net Framework ? [modified]

Hi.

I'm gonna create a list with all classes and namespaces name in .NET Framework 3.5 (Programmatic)?
Would you guide me how I can do it ?

Thank you.

Not guide you, but I can suggest two starting points for your research;
- Reflection
- Scraping the MSDN site[^]

I guessed as much since you're on a programming forum. Let me rephrase;

- Reflection
That's like asking the ".NET Framework" that's installed on your PC what the names of the classes are that are in it. It's like asking the system itself, "what's the stuff inside you?"

- Scraping MSDN
That's like programmatic reading the website of Microsoft that lists and describes your classes. This way you'd be building something that reads webpages.

You still haven't answered my original question; why do you want to make this list? Smile | :)

You can use Reflection to iterate through all classes and namespaces in the assemblies you wish to explore.

So I ought to use a File Explorer to explore all assemblies and then get the classes name with Reflection ?

You could use a System.IO.DirectoryInfo to iterate "%SystemRoot%\Microsoft.NET\Framework\*.dll" and use Reflection to load each assembly and iterate all the classes therein, but why would you want to? Is it homework? Confused | :confused:

How to transfer text to label from richtextbox

Hello,
I have been trying to transfer text to a label from richtextbox. The problem is I can't equalize font and text color. For example, if I write "Hello World!" it seems the same on label but when I write "Hello World!" it seems "Hello World!". Is there a way to equalize them?
Thanks in advance.

label1.Text = richTextBox1.Text;
label1.Font = richTextBox1.Font;

A label is limited to using a single font to display it's text. That means one color, one font-family, one style. There are some custom components on the internet that can display RTF, or you can use the RichTextBox itself to display it.

This is a parent form and not a parent control
This will work

private void StripItem_NewReg_Click(object sender, EventArgs e)
{
NewRegToolWindow = new NewReg();

//NewRegToolWindow.Parent = this;
NewRegToolWindow.StartPosition = FormStartPosition.CenterParent;
NewRegToolWindow.ShowDialog(this);

Wouldn't it be easier to do this from the policy? For each user, you would take away the privileges for those actions (and any other actions you see fit).

Also, please type "please" and not "plz". txtspeak is so very insulting.
