i have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?
I have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g. [43] [85] [93] [1] [0] [17]..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.
i have 20 textboxes and i want in to see in a label how many numbers are in the textboxes (because some of them are empty) not the addition just how many textboxes have numbers.
[URL] I'm trying to do an exercise on that website but it doesn't show the answers to the exercises..
I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part: Ignore the second if I was desperate xD Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code].....
And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?
I have two functions to find the high and low numbers from 5 different textboxes. I want the high in one label (which I have) an the low in another. I cannot seem to get the low number to be anything other than 0. Here is the code:
I want to make a program like this but not with random numbers ! I want it with A list from ".txt" or "from number 1 to number 999999999"

i am trying to make 8 different random numbers in 8 different textboxes. the problem i have is that it doesn't load up when debugging. i have visual basic 2005 [Code]
I have a problem whereby I have 10 text boxes and I don't like to use the same code for each and every text box that allows users to input only numbers, which could be very long and messy coding.
Is there any shortcut that I can set all (not just one) text boxes to allowing user to input only numbers?
On Form Level, I use following codes to make textboxes to accept only numbers,How to add these codes in main module, instead of of writing these codes on every form.
If TypeName(Me.ActiveControl) = "TextBox" Then With Me.ActiveControl If Not IsNumeric(.Text) And .Text <> vbNullString Then
I have created a sample program that dynamically created up to 7 numbers of Labels and Text Boxes. Here I want to add those numbers inputted by user on dynamically created text boxes.
Dim WithEvents TxtBox As TextBox Dim WithEvents LblLabel As Label Dim NoOfControl As Integer Dim A As Integer
I have made my calculator and it has 2 textboxes where the 2 numbers (or values go for addition and subtraction) are input and a label where the answer appears. There is other things on the page such as quit, clear etc thats all done but i have one query. I noticed while testing a problem occurs when only one number or value is put into a textbox and a command is hit. For example. one textbox (txtnumber1) has one number in it then i hit multiply and it says the error of course because its not programmed to deal with this (or divide by 0 of course) so i was wondering how i could make so when this happens a MsgBox appears saying a value must be in both boxes or when divded by zero is says something similar.
The line of code:
Private Sub blah blah blah...
If txtnumber1.Text = False Then MsgBox("Please Input Valid Value")
I have 5 columns of 11 textboxes each on my form the textboxes are generated with this code

i need a code to generate all the possible combination of the numbers a user types into the textboxes i have two images (Panel3: the textboxes where added during design time) image2: the textboex were added using the code i gave about
generate all the possible combinations of numbers typed into the textboxes (Example see panel3.jpg image),
The user will type in the desired unique numbers into the textboxes without repetition (Please see the image i did not repeat any number, so can the code detect when a number have been typed twice?) Else when running the program i will be carefull not typing two numbers twice, but its adviceable to detect when a number is typed more than once.
Then the amount of unique number the user will type or supply to the desired textboxes does not matter here and as you can see in the image the amount of numbers in each column is not the same ie it may or may not be same amount (but number must be unique. Please try and see if it can be done to prompt user to enter the amount of numbers to supply in each column)
Then After supplying the numbers just like the one in Image, The button Click will generate all the Possible Combinations of the all the numbers typed into the textboxes in the columns.. Then After generating the combinations in the Listbox, the next Button will be able to delete them from the Universal 90c5 just like the former.
I need a variable divider ex. i have numbers from my textboxes in the range of 20 to 60 i want a divider that will divide them in a range of 2 to 6 so if the number is the lowest 20 the divider will divide him with the lowest of his range number 2 if the number is 40 the divider will divide him with the number 4 if the number will be 45 the divider will divide 4,5 and so on a variable divider.
i have several forms each with a specific pet. i want to be able to have the user press buy and then the price of the pet will be added to the reciept form. lets say dog1 is $400.
dbldog1 = 400 dblsubtotal = dblsubtotal + dbldog1 on reciept form i would have lblsubtotal = dblsubtotal
Im currently doing a small programme of a register system. I need to add a new group box filed with a few textboxes and a couple comboboxes for each entry in a access 2010 database. for example if i had someone called bob in my database with his details i would like the GUI of the VB app to add in a new textbox for the name, a textbox for the address ect in a set order, this needs to work for multiple entry's so the textboxes ect don't overlap but be placed neatly below the added textbox.

Whats the best way to add an adornment layer to legacy controls, or in other words you know jetbrains refactoring tools, how do they draw the squiggly lines under incorrect text? Also on another note can one draw said adorments on controls not under the direct reference of the application, ie using a handle? If you have insights, or just theories,
The three labels "Floor" "Typ." "HeadsI can insert once fine but multiple times only the third instance is written to the form.I have 2 textboxes to test that the Label.Name is changed but I can't make the Label.text stand for each label. I am certain this will occur too with the textboxes.I also need to keep track of these boxes for further use with the program.

I've tried following the Microsoft instructions to add multiple Textboxes to my form, but just cannot get it to work.Thus, I've deleted everything I wrote, so I don't have code to post. Is there a very simple way to add multiple TextBoxes to a form and be able to index them? If it's too lengthy, Is there a workaround?
I have a couple of textboxes on my form. I'd like to give the user the opportunity to spell-check these textboxes so that they can correct their mistakes and then update the contents of the textbox into the database.
Only thing is, I'm not sure where to begin. I found this thread by Martin Liss, but it errors out for me as it's not .NET.
I have a datagridview named Partcotdatagridview. In this datagridview, I have two columns. The first column has a combo box with some names in the data source such as John, David, Alex. The second column is designated for amounts. Each person will have different entries in the datagrid I will select a name and enter an amount for that person. I would like to display the total for each person in 3 different labels in a different form.
ok the problem is that when a button is click I want it to add 1 (+1) to a textbox. This process will keep on going on till I tell it not to...How would I just keep a running total of whats happening in the textbox...What I mean to say is that if I pressed the button 10 times, instead of it showing:111111111 I want it to automatically add the numbers up to show 10 instead.
