i've got my basic AutoTyper ready (well and one with autoupdating etc in it) but it's only a singular line. [Code] What I want to do it to type multiple lines, I know I'll have to enable multiline on the TextBox. I want it to type one line per time interval using 1 timer. I don't know how but I know it would have to count the lines but from then on I'm stuck. I will need to make it type line 1, then on the next loop line 2 and go on until it's reached the amount of lines from the count then repeat from line 1. [Code]

I'm using a custom webbrowser to display a special intranet for my company.I need to be able to display a custom keyboard whenever the user can type in the webbrowser. So if they click on a textbox within the page to type, this custom keyboard appears.when the user is in 'typing mode'. I thought maybe checking when the cursor changes to 'ibeam' which is the typing cursor? How might I do that, or is there an easier way?
View 1 RepliesI want it when I type anything, it will start at the third character of the textbox. Ex. I have this amount textbox that has .00 on it, whenever I type numbers it will start after the period. So if I type 300 then it will show 300.00

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.

I need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.
View 6 RepliesI have a form that allows users to enter information into a few textboxes. When users click save, the information will be transferred into the datagridview.
My problem now is, for instance, there is a textbox called "Price" with the datatype "money" which users are only allowed to enter numbers. If users enter alphabets, errors will occur. I don't wanna use try catch, I would like to try different methods such stopping users from entering anything into the textbox when the datatype isn't correct - nothing will appear in the textbox when users hit all the keys in the keyboard except for numbers.
I am using String.Format("{0:C2}", -1234)to format numbers.is always formats the amount to a positive number, while I want it to become $*-*1234

View 9 RepliesI just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.
Is there a .string format code to display a number such as
123.456 as "123456E-3"
123.456.ToString("E") -> "1.23456E002"
which is of course correct, but i want the format to be free from the dots and commas which cause so much hassle when sending to other regions in the world

Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.

' allow only numbers and the Backspace key
