Textbox2 Contains A Number And If The Number Entered In Textbox1?
May 25, 2012
Have a very nooby question here, textbox2 contains a number and if the number entered in textbox1 is higher than textbox2 i wish to display a message box but the following doesn't seem to be working properly?
Sometimes it lets the user enter a higher number, maybe I am doing this wrong?
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
[Code]...

How can I get the sum all the values a user enters into TextBox1 to display that sum into TextBox2.The user is going to enter one value one by one. The user enters '1' into TextBox1, therefore, TextBox2 should display '1'.If the user than enters '2' into TextBox1, TextBox2 should display '3'.If the user enters '2' into TextBox1, TextBox2 should display '5'.And so on.TextBox2 should only display one value at a time, not one after another.I am using double because I need decimal places.I have a ListBox1 where it displays all the values entered by the user in rows one by one, but I prefer not to use the ListBox1 to get the sum of all the values entered in TextBox1 and to have TextBox2 show that sum. Because in that ListBox1, I have few other things in there, like Strings, which will not allow the sum of all the values entered in TextBox1 to be calculated and displayed in TextBox2.Not sure if this matters or not, but I thought it might.So only need TextBox2 to have all the values entered in TextBox1.If 1 was entered in TextBox1, TextBox2 shows 1.Then 2 is entered in TextBox1, TextBox2 will show 3.

Let's say that you have a texbox labeled TexBox2 and you don't want it to be seen when the program runs because TextBox1 pulls information from TextBox2 and it shows up inside of TextBox1. How would you go about doing this?

is there a way of making a random number generator, which would clear out 2 random boxes out of 3 even though there are 4?
lets say there are 4 answers one in each textbox. if textbox1 is correct, can i make random number to be between 2 -4 and clear randomly either textbox 2 and 3 or textbox 2 and 4 or textbox 3 and 4 and same for other text-boxes if they are correct?
i thought about making two random numbers picked randomly then use alot of if statements, but did not realize i am getting into something ridiculously long. I think there must be easier way than that.

I have made an countdown app that is working in a normal way (added picture of it). Now when I select a number in the numeric box and click start, it starts to count down from that many minutes, but what I want is the number I put in the box *3. So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).

I have a UI that uses datagridviews / bindingsource / datatables of typed dataset for data entry. The dataset itself is serialized to a varbinary(max) in SQL. (i.e. no tableadapter, backend schema).I would like to limit the number of rows the user can enter into some of the grids (the data is used to fill PDF forms and I don't want them entering more rows than the forms can accomodate.).I have subclassed the datagridview, added a rowlimit property and tried to manipulate the AllUsertoAddRows property
Imports System.Windows.Forms
Public Class dgv
Inherits System.Windows.Forms.DataGridView[code]......
The behavior I see is that the messagebox comes up after leaving the max row even when the user is trying to leave the grid. I can lose the messagebox and deal with notification some other way but I thought someone else may have come up with something a little more sophisticated to handle simply causing attempting to add to many records to navigate out of the grid to the next UI control.
