I had a small query relating to using an If statement.
Is there a short / easy way to populate 2 or more text boxes with different text if an if statement is true.
So.
If A = 1 then TextBox1 = "AA" and TextBox2 = "BB" etc
I've tried doing it with 'And' '&' but just keep getting a 'False' appear in my Textbox1 and nothing in the 2nd or 3rd.
I'm using Vb .net 2008
I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

The project was to modify a previous payroll system project, which had a base class(employee) and 3 derived classes(salary, commision,and base + commission) under it by adding 2 more derived classes(piecework and hourly).Before I stated the modification, everything worked fine. When I would run the program the 3 types of employees would display in each output text box. The same thing is supposed to happen after I added the 2 additional types of employees, but now when I run the program, both output text boxes are completely blank. I'm not sure why I can't get anything to display in my 2 output boxes and all of the coding looks correct to me.

I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.
trying to write a simple app that queries an access DB based on date .. the SQL looks like this and works fine with a date hard wired into the select:
SELECT Terminal_ID, SUM(Transaction_Quantity) AS Total
FROM tblTransaction
WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > #1/1/2009#)
GROUP BY Terminal_ID
On the main form I have a monthcalendar control named 'FromDate' and a DataGridView control that shows the SQL results.
How do I get the user's selected date incorporated into the SQL statement that returns the results in the datagrid?
Something like:
WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > Fromdate)
...but obviously there's much more to it.
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
i am trying to automatically generate multiple text boxes on a form with the following code
Private Sub CreateTB(ByVal x As Integer)
Dim y As Integer = 1
Do Until y = x
[Code]...
i need it to generate as many text boxes as the variable x states, so i used the do until loop thing. But i am stuck when it comes to naming the text boxes because obviously all the text boxes cannot share the same name. so i would like to know how to programmatically name each textbox uniquely.

I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)
