Inputting Numbers Into A Textbox And Formating The Numbers?
Jul 30, 2009I 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.

View 19 RepliesOnly Numbers In The Textbox?
Oct 24, 2010I have a textbox where the user inputs the employee number, but it must only accept numbers.
I have coded some lines in the textbox's TextChanged event and almost have it. but when I adjust it to eliminate other characters it triggers itself (recursive). that is not a big problem since the second time does nothing but I dont like the unprofessional way its handled.
But the real problem is that I cant get it to stay "blank" when the user erases all my code always puts "0" on the texbox.
Another thing is that when a non-numeric key is pressed, after the code dismissis it, the cursor goes to the start of the textbox messing up the input.

Sep 29, 2009I have a problem in putting the telephone number using the datagridview. I have build 2 forms which is form1 and form2.

But the problem is that, I grab the telephone number which has been display in the form1 first textbox to the second textbox in the form1. I could not get the telephone numbers.
