Quoting MSDN topic for SerialPort.DataReceived Event[^]:
The DataReceived event is raised on a secondary thread when data is received from the SerialPort object. Because this event is raised on a secondary thread, and not the main thread, attempting to modify some elements in the main thread, such as UI elements, could raise a threading exception. If it is necessary to modify elements in the main Form or Control, post change requests back using Invoke, which will do the work on the proper thread.
If you used the DataReceived event without trouble, you probably accessed no Ui controls or were lucky.
Ensuring that an event handler is executed on the right thread is no concern of the event with no difference between custom events and the ones provided by classes of the framework class library.

Just maybe i am a bit newbie in c#, but got such a problem...
private void Form1_Load(object sender, EventArgs e)
{
this.grupeTableAdapter.Fill(this.bangaDataSet.Grupe);
}
Cant to insert any new information to my db.

string one = textBox1.Text;
string two = textBox2.Text;

this.grupeTableAdapter.Insert (Convert.ToInt32(one), Convert.ToString(two));
this.grupeTableAdapter.Fill(this.bangaDataSet.Grupe);
bangaDataSet.AcceptChanges();

Assigned all this to button, but nothing happens. In db one column is numbers other just information... Maybe anyone know, how to update that information, what could be bad ? Or at all all this code is bad ? Smile | :)

Sorry for my bad english Smile | :)

Send Html file to printer

Hi all,

I want to send a html file to the printer...
So far i have the following...

<br />
string _filePath = "C:\\newFolder";<br />
Process myProcess = new Process();<br />
myProcess.StartInfo.FileName = _filePath + "\\test.HTML";<br />
myProcess.StartInfo.Verb = "Print";<br />
myProcess.StartInfo.CreateNoWindow = true;<br />
myProcess.Start();

I can get it to print BUT i don't want the user to select the printer because the user already selected the printer he wants to use and i saved this selection. How can i use the selected printer previously saved as the printer to use now when the file needs to be printed?

The segment above brings up a window where all the found printers are shown and when one is selected the printing of the html file begins.

Since you're talking about a DataGridView (DGV) compared to a DataGrid(DG), I'll assume you're using VS2005.

Check out the CP article Here[^]:

I ended up buying the book and its a great reference for all your windows forms databinding/datamanagement needs.

You'll have to expand a little more. Are you referring to having different columns of comboboxes with different sources, or having one column of comboboxes, but having each separate combobox have a different source?

Nope !!
Two of the most common types of message boxes are alerts and confirms.
A confirm message box prompts the user if they want to continue, and provides two choices: "OK" and "Cancel".
An alert message box, on the other hand, simply presents a message to the user. There is no choice, here, just an "OK" button that the user must click to dispose of the message box.

If it's ASP.NET, then you are going to have to write Javascript to show it.
