i have one label one button and 5 textboxes and i need to see in the label one number that randomly will choose from numbers that allready are in a group of 5 textboxes
View 21 RepliesI need to have 4 text boxes and three command buttons. One button should be used for exiting the program, one button should be used for clearing all of the text boxes, and the last button should be used for any calculations/conversions. You should also have a radio button group for the user to choose entry temperature type.
One text box should be used for the entry of an initial temperature. The radio button group will then allow the user to select the entry temperature. When the button is clicked for conversion, the other three text boxes will populate with answers to the conversion. and if I enter 37 degrees Fahrenheit, the Fahrenheit text box should read 37 after the conversion.)
I have a group of 3 numbers:
-SideA
-SideB
-SideC
I need a way to detect which one is the largest, and which is the smallest, and assign them to a variable.If SideA is the largest, then it is variable C, and SideB is the smallest, so its variable A, leaving SideC as variable B
I am creating a sailing score points program and want to create something like: what TEXTBOX has got biggest number that is between (TEXTBOX IS BETWEEN NOT THE NUMBER) [ and ] And it's subtracts that number what is in that box from the textbox3 when possible then how to do like:

I would like to create or rename a group of sequential textboxes on my VB.NET windows form in the design environment. I currently have 70 textboxes. Right now they are named as TextBox1...TextBox70. I would like to rename all of them to something else like Conveyor1...Conveyor70. I am going to have other groups of textboxes on the screen as well, so I need a quick method to either create them with another sequential name or rename the entire group.

I have to check the following:
a) group number is neither 501 nor 062

I am using VB .net 2010 express from microsoft. I have a numeric up down box to display a variable that the user can choose a number for. Then I have a text box that I want to display a result of the updown box * 1.5... So far I have the following... What do I need or need to change? I have the integer variables initialized or whatever with Dim statements as follows -
'speed variables
Dim CruisingSpeed As Integer 'cruise speed - updown box
Dim FlankingSpeed As Integer 'Flanking speed - will be cruise * 1.5

It says that it cannot convert the up down box into an integer... I need it as an integer to calculate the other number...

I have ten numbers like 1.1,2.5,3.7,4.9,5.4,6.2,7.6,8.9,9.0,3.56
How I can find the largest number in the group?? I can do comparison of two number and repeat the process but it is very long, is there any other ways??
Say for instance, I gave you the numbers
1, 2, 3, 4, 4, 6, 9, 1, 3, 4, 5, 5, 2, 4, 7, 9, 1, 5, 3, 6, 6, 8, 1, 1, 4, 7, 7, 8, 2, 4, 2, 1, 9, 1, 0, 1, 6, 3, 2, 1, 8, 8, 9, 8, 1, 5, 3, 2, 3, 4, 7, 9, 0, 1, 2, 4, 7, 4, 3, 9, 7, 2, 0, 1, 6, 3, 8, 1, 2, 4
What number appears more than any other number?This is very important to me, ...I need to find the MODE, of those group of numbers, ...the way that I did it before, I would make 10 TextBoxes, and have another text box to enter the number, and when the number gets entered it would increment the value of which ever textbox the number was in the main textbox, so if I entered a 1 into the main textbox, then the zero in textbox (1), would be incremented to 1, and if another 1 was enered and the button was clicked, the 1 in the Textbox for 1, would be incremented to 2, because 1 has a popularity of 2 now and has apeared 2 times..
Here's some code, to show what I've come up with by myself.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ONE.Text = ONE.Text + 1
End If

On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If
Next

View 7 RepliesI'm developing an app that should allow the client to add several content sections to a page (in tabs). However I haven't found a way to easily create a form for editing the tabs.Assume for now that a tab just contains a title. I have a form that adds a tab, that's simple. But I also want a form that displays a text input for each tab and allows the titles to be edited and saved. I'm struggling with two main concepts:How to dynamically display the fields after grabbing the tab data from the database (each tab has its own row in the table).How to loop through the submitted data and update each tab in the database.How to select a particular text field from the number (e.g. given "1", how to select the element with ID "TabTitle_ 1".[code]I thought something like TabTitle[0] would be acceptable and allow for easy looping (as it does in PHP) but it's "not a valid identifier" apparently.It's very possible I have the approach completely on its head.

View 2 RepliesI was about to create a program about CPU Scheduling (SJF Nonpreemptive), Now, I want to ask the user to input the no. of processes ,then based from the user's input I would display exact no. of text boxes where the user could enter the value for each process then store it in an array. But I don't know how to code the text box., I'm new to VB.net and I'm used to it's 'drag and drop' nature. I just want to know how the code to output this text boxes. and is it possible to have an array of text boxes?

The above code is from a small program I have written. This test is done on about 30 textboxes I am using for the user to enter number.
The following is the sub routine that is called.
Sub ShowError()

End Sub
Here is what I want to do but it won't work.
BoxName.Select()
This is so I can put the focus on the different boxes that might contain an error.
