If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.

My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

I have a form that contains multiple conditional or if statements on several defferent for controls.
Example: Radio Buttons, TextBoxes and CheckBoxes.
I am intending to create an order form(demo) where the user can select multiple products.
I have a default order number that changes by one everytime an order is successful.
An order is only successful if all the information on the form is entered correctly.
My question is where do I insert the code for the order number?
Basically for the order number I have a counter that count by increment of one if an order is successful.
Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.
Where do I add the condition for the order number since all the fields must first be completed.
Do I have to create a whole line of if else statements?

I have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed.
I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.

how one would go about validating input into a textbox for example:
Lets say the first letter the user enters has to be 'A' and the third letter the user enters has to be any number ranging from 0-9 and the length of their input cannot exceed lets say 10.
This is what I have so far:
If txtOperatorID.TextLength > 10 Then
bErrorOccured = True
sErrorMessage = sErrorMessage & "-No more than 10 chars" & vbCrLf
[Code]....
The coding for the length works(is there a better way to do this)? The coding for the first letter to be A works but then I have no idea how to set validation for any proceeding characters entered. Am i right in thinking I have to find their position somehow in the string if so how?

I want to allow the user to enter symbols using the keyboard. I'm checking the textbox onkeydown event for the pressed key and then change it to a symbol, for example if I would press 'a' then the textbox would show '☺'. But the problem is that the textbox shows both 'a' and '☺'. Is there a better event to check this, or better way to do this?[code]...

I'm having an issue with converting the name input from the format of (Last, First) within the same textbox to (First Last) in a listbox via a function.

Manipulating these strings is killing me.Below is the code that I have written, manipulation of the strings must be in one function for each the invoice and the and the name issue....
