Adding Numbers In Textboxes
Jun 27, 2011
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?

[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 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?

I figured there would be some simple way to set up some textboxes to allow ONLY numbers or ONLY characters, however I haven't found an easy way yet.
Is there a simple trick to setting something like this up? And if so, how would I do it?

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")
End Sub
I however have not been able to make it work.

I have 5 columns of 11 textboxes each on my form the textboxes are generated with this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'column 1 textboxes
[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.

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.

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.
