well, the code is not so complicated. private void display(string data) { checklength(data.length); txtdisplay.appendtext(data); } private void checklength(int num) { if((txtdisplay.text.length + num) > txtdisplay.maxlength) txtdisplay.reset(); } Anyone wants to test, creating a form with multiline textfield, just running a forever loop and passing a string to the display function. Thanks. Kyah

Hi all, I have a program running without stop with a textfield to display data. I reset the textfield whenever its maxlength is reached. The program ran well but one day I saw my computer was restarted and I looked at the application event and saw that it was caused by Running time in .Net . I wonder if anyone knows this running time issue or a similar problem. Thanks. Kyah

the code is very simple. void proc() { ... callreport(1, 'o'); ... } void callreport(int a, char b) { reportJob = new ExReport() //The ExReport is a Crystal Report connected to // SQL Server 2000 reported by a store //procedure with one input type char reportJob.SetParameterValue(0,b); //"The error happened at this line ... } That's all. The code looks simple but it gave me a lot of headache. Thanks

Hi, I have a problem with the exception "Value does not fall within the expected range" and I haven't quite figured out what is wrong in my code. I have a store procedure that has a declared char for input. The store procedure is used by a Crystal Report filename. I want to pass a char from C# application that calls the Crystal report and passes a character to it. Somehow, I got the exception. I wonder if the character type in VS .Net 2005 is not compatible with a character type in SQL Server 2000. Any help? Thanks. Kyah:confused:

Hi, I'd like to make a listbox display multilines to user without using scrolldown when another event is clicked. And the same listbox shows only one item when another event is clicked. Ex: when you click a button A, then a listbox B shows multilines of items. And when you click the button A again, the listbox B shows only one line. Thanks. Kyah:doh:

Thanks Roy and Stefan for your help. Kyah :-D
