Quoted from MSDN -Click here to read the article[^]- "Note The MDI child form you create in this step is a standard Windows Form. As such, it has an Opacity property, which allows you to control the transparency of the form. However, the Opacity property was designed for top-level windows. Do not use it with MDI child forms, as painting problems can occur." Regards:rose:

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?

chkListBox.SelectedIndex = index; chkListBox.SetItemCheckState(index, CheckState. ...);

Hello please test below code : Application.ExitThread(); May be it's usefull ! Regards.

you can you this too for (int i = 0; i < this.checkedListBox1.Items.Count; i++) { this.checkedListBox1.SetItemChecked(i, true); } Regards Shajeel

Erhmpff... this is really back to basic... Create a solution with two projects - Executable project (name : ExeProject) - Class library (name DllClassLibrary) in the class lib. create a class containing the following function : public string MyRichText() { StringBuilder sbMyText = new StringBuilder(); sbMyText.Append("Text text text and even more text"); return sbMyText.ToString(); } Then from your executable project, create a reference to the class lib and add a form containing a textbox. Name the textbox for instance txtTextFromDll In the Load event of your form add the following lines : DllClassLibrary.ClassName objMyClass = new DllClassLibrary.ClassName(); txtTextFromDll.Text = objMyClass .MyRichText(); you're pretty done there (except for when i miss something) - - - --[ i love it when a plan comes together ]-- - - -

i am new in C#. So while going through some document i came to know that we can use table(table means 'tableLayoutPanel') & DataGrid(DataGridView). But since i want user should not enter wrong values i am confused which one to use & how to use...? Can u suggest me any document to learn it. I am using Visual Studio 8. Thanks, Vinay

Sounds like what you are really talking about it the echo from a modem, the serial port itself has no echo. If I am right it all depend on the modem you are using. Most "Hayes" modems use &E0 and &E1.

The problem with ur Thread is repeatedly polling for Data in the queue. We can reduce the CPU utilization as far as possible by making ur thread work only when there is something in the queue and the way to do is explained in my previous post. USE A ManualResetEvent there in ur loop.

Thanks... can you help me for one more thing... If i am waiting for some text on my SerialPort & after receiveing that text only i have to transmit some text then how i can do that. e.g. say i've to set the date. & am waiting for text "Set Date : "... & after receiveing this on comport i have to transmit "08 NOV 2006" Thanks for your replies, Vinay

Hi, I'm not sure if this is your problem, but I think you don't have defined baud rate, parity, data bits and stop bits for your comport. OR Try send your comport trough parameter to your child form. I hope it helps, Jure

Once again: Please read the error messages you get and try to understand them. If you don't understand them, post them here so that we can help you! With the code snipplet you posted I think the problem could be that you declared f1 as Form but in fact it's an instance of ChildForm. The class ChildForm does have a public RichTextBox named MyRichTextBox, the class Form doesn't. So to get your code to work you should change public Form f1; to public ChildForm f1; and your DataReceived event handler should read string ReceivedData = comport.ReadExisting(); ReceiveLog(LogMsgType.Incoming, ReceivedData); if(f1.MyRichTextBox.InvokeRequired) { this.Invoke(new EventHandler(delegate { f1.MyRichTextBox.AppendText(ReceivedData); } )); } else { f1.MyRichTextBox.AppendText(ReceivedData); } Regards, mav -- Black holes are the places where God divided by 0...

Thanks, I am new in C#...Can you told me little bit in detail... How to send ref of parent form in constructor of child form ...? regards, Vinay

With what u told i think it is not posible to add different clicke events dynamicaly & differet procedures to handle that events... Thanks for your replies, Vinay
