View 4 Repliesi am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text
textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.
I would like to include the line numbers on the left side of a multiline textbox, much like what Notepad++ has. It should scroll along with the rest. Is this possible?

Design and code a project to calculate the amount due and provide a summaray of rentals. All movies rent for $1.00 and all customers receive a %10 discount. The form should contain input for the member number and the number of movies rented. INside a groupbox display the rental amount, the 10 percent discount, and the amount due. inside a second groupbox, display the number of customers served and the total rental income.(afterdiscount).Include buttons for Calculate, clear, print and exit. The clear button clears the information for the current rental but does not clear the sumarry information. A print button allows the user to print the form. Do not allow bad input data to cancel the program; instead display a message to the user.[code]...

Is there a built in way to know when a user is done typing into a textbox? (Before hitting tab, Or moving the mouse) I have a database query that occurs on the textchanged event and everything works perfectly. However, I noticed that there is a bit of lag of course because if a user is quickly typing into the textbox the program is busy doing a query for each character. So what I was hoping for was a way to see if the user has finished typing. So if they type "a" and stop then an event fires. However, if they type "all the way" the event fires after the y keyup. Like measuring the time since the last textchange event and if it was > than a certain value then it would proceed to run the rest of my procedures.

VS 2008 Preventing characters being entered
View 1 RepliesI have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then
MsgBox("Sorry, but letters are not allowed!")
