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 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.
View 37 Repliesi 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?

View 3 Replies[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 would like to display the multiple records in multiple textboxes Following is my tables and data:
tblJan with these data:
col id

now i want to display the value 10 in one textbox and the value 20 in another textbox and so with the value 30 in another textbox..
Okay this is the simple thing I'm trying to accomplish. I can get richtextbox1 to add to listbox 1. but i cant get both to add. the compare works fine. I'm stumped.

I have dynamic class with varied numbers of property. At one time I need to save all data from this class. So, to do the For/Next or Do/Loop, I need to know, how many properties in class for now? Is it possible to findout the property numbers and after - property names list?
For example. I have a class INI, were was .Path as preexisted property. Then the few properties has been added and INI start consist of .Path, .Size, .Color and something else.
I dont want to keep in mind all properties has been added. All I want to get some simple loop to read all properties names and values to dump it to the file. Some sort of this[code]...

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

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.
View 21 RepliesI have a program that someone else designed the form on and sent to me to populate the code. I am not sure what could have been done to cause this problem, hoping for a quick oversight on my part. There are several fields of textboxes that the user enters numbers in. Normal behavior for textboxes is when you tab to them the current contents are highlighted. On one of these textbox fields, and only that one set of textboxes, the contents are highlighted like normal at first, but after the user edits the content of the textbox, if you tab to it again it will go directly into edit mode instead of highlighting the contents. Each textbox in the field does this individually, so if you just edit one, all the rest will continue to highlight contents until you edit them as well. It appears you don't actually have to change the value of the textbox, just entering edit mode and getting a blinking cursor is enough. I cannot find a difference in the properties of these textboxes compared to the rest.

Ok I need to have a message box pop up when a user clicks the "Add Patient" button and the message box should have multiple textboxes which include Patient name, Patient ID, etc. I guess my question is can I do this with a message box or do I need a new form to pop up when the button is clicked. The form is connected to a database and the info entered should be added to the "Patients" data table.
View 8 RepliesI have a form on a program i am working on that i need to check if all the textboxes hold a separate value when a button is clicked. I know that i can use comparative operators to check the values are different, but i am using 6 different textboxes, and don't fancy typing. [Code] 36 times over, could somebody point me in the right direction for an easy way of checking that 6 textboxes hold different values. Also, as a sidenote, i would like to know if there is a way to check if all 6 are numeric in an easier way than typing is-numeric(textbox1).
View 10 RepliesIs there a way to copy multiple delmited items and paste them into multiple textboxes on a windows form at once?
I have a form with 5 text boxes, if you click in the first textbox and press the tab key it jumps to the next textbox.
so lets say I copy data from notepad :
ThisShouldGoIntoTextBox1
ThisShouldGoIntoTextBox2
ThisShouldGoIntoTextBox3
ThisShouldGoIntoTextBox4
ThisShouldGoIntoTextBox5
and click on the first textbox on the form and press paste, it will only paste the first line.
Is there a way to add that "tab" character to the end of each line, so when I paste the data, it will automatically fill all the texboxes?
I know this is possible in browsers with plugins, but i want to do this onto an existing windows form which code I am not allowed to change.
