Hi, I am developing a MDI application. In this application on click of some menu items I have to display some forms(say MenuForm1, MenuForm2, MenuForm3) with some data. But at the same time I want one form(say BackGroundForm) which is a child form of my MDI application should be active in the background of the form which gets displayed on click of some menu items. If I declare those forms(MenuForm1, MenuForm2, MenuForm3) as child & if I pop them up using ‘show’ then for 1st time they are visible in my application but next time if I click that menu item then they are not visible. Same problem I’m facing if I don’t make them as child of my MDI & pop them up using ‘ShowDialog’. I am hiding forms(MenuForm1, MenuForm2, MenuForm3) on click of a button which i placed on same forms(MenuForm1, MenuForm2, MenuForm3). I want that ‘BackGroundForm’ in my application because I want to put some button controls on one form & that form should be active all the time until the application is running. So I had put some buttons in this BackGroundForm & I cant put buttons on MDI parent form . How I can solve this problem in my MDI application…? Thanks in advance, Vinay

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

Thanks for reply... But i am not using ASP.NET & i am using .NET 2. In my application i just want to set some parameter valuse to new values & at the same time i've to display old valuse on form with table/datGrid (old values i'll read from SerialPort communication & display it in 2nd column). My 1st column will be my parameter name & last column will be new vallues entered by user. On another button click event , i've to send those new values on serial port. Thanks, VInay

hi.. In my application on a form , I want to list some paramter values as old & new. User entered values should be there in new column. But in c# we can use 'table' & 'DatGrid' for this. So which one is better for my application as i want user to enter those parameter values in a perticuler range only. Can i give dropdown combobox in table or datagrid so that user can select with only values given in that combobox. Can i do it with both Datgrid & table. Can any body give me any good document to do this using datagrid/table in c#. Thanks in adavance, Vinay

Hi... What is the command for 'EchoOff' & 'EchoOn' in C# for SerialPort communication in C#. Regards, Vinay

Hi... Here is complete code what i am doing... private void ComportThread() { for (; ; ) { if (MsgQueue.Count > 0) { string firstItem = (string)MsgQueue.Peek(); comport.Write(firstItem); MsgQueue.Dequeue(); } } comport is object of serialport class & MsgQueue is object of Queue... can u tell me now what is the probelm exactly... Regards, Vinay

hi... In my application , i'm using a thread to check for Queue contents. If i have any data then i have to transmit/receive that data. But my application is taking maximum CPU time if i'm using infinite for loop in this thread & because of this my CPU is using maximum time for my application(around 95%). & if i'm not using this for loop i am not able to transmit/receive whatever data is there in queue. private void ComportThread() { for (; ; ) { //Check for queue contains, if data is there then trnasmit/receive } } What is the problem...? Thanking you, Vinay
