I've got a function that allows only numeric characters to be entered into a text box. My question is how to alter the code to also allow periods (charcode 46).
[Code]
but it does not seem to be working (still only numbers allows, periods still not).
I know that the following code blocks the usser from ussing spaces in a textbox however how do i allow the user to only use numbbers and a fulstop (so i can add values like 1.5)[code]
View 4 RepliesI was wondering how can I get the two numbers right of the decimal period? If I had 2.85874125639, I would want to get this: 2.86 since it was rounded...
View 4 RepliesI'm beating my head against the desk on an advanced level solution in the VB 2010 book, and can't figure out what I am doing wrong. This is the exercise: JM Sales employs 8 salespeople. The sales manager wants an application that allows him to enter a bonus rate. The application should use the rate, along with the 8 salespeople, in an array, to calculate each salesperson's bonus amount. The application should display each salesperson's number (1 through 8) and bonus amount. as well as the total bonus paid, in the interface.
1. The txtRate control should accept only numbers, the period, and the Backscape key.
2. A one-dimensional array should be used that has elements initialized to the following sales amounts: 2400, 1500, 1600, 2790, 1000, 6300, 1300 and 2700.
I have the interface created and its error free (for now) but its not doing what its supposed to do. It's supposed to show something like this. I can provide screenshots if necessary. [code] but what I get is a list of 0.00's in all of the above fields. What am I doing wrong? Heres the code finally, sorry if I was overly descriptive. This is my first time doing one of the advanced exercises, maybe I should go back to intermediate.
how can i make an auto capitalized text after typing a period and two spaces in richtextbox?
View 1 RepliesI am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
is their a way to do this to text? EX : 1p2a;ss4w/o4r=dg It spells out password

View 4 Replieshow could I make it so that numbers spin around in a text box before being selected. I have five text boxes the start button spins the numbers 001 to 500 in each text box, then when a button under the first text box is pressed the numbers stop spinning and the chosen number is displayed, you then press the button under the second text box to stop the spin and that chosen number is displayed.My thoughts are, have the first button select the five numbers and place each in a text box but have the text boxes visible set to false, have five more text boxes, visible.true, that show spinning numbers, when the button under the first box is pressed the textbox with spinning numbers is set to false and the one with the chosen number is set to true.This is only for decoration purposes so that you get to see the numbers spinning before you appear to stop them.
