Put Back In The Text Boxes Where It Originated?
Aug 15, 2011
So heres the deal i am still learning VB (bet you guessed that), now what i am tryiing to do is create a form with a number of text boxes (say 25) where a user can enter their own data. Which they can then save as a file and reload. Now when they reload the file the data needs to be put back in the text boxes where it originated
Which would be the most efficient way to write this?, would i write it ti a csv file or a database or text file, as you can tell i'm a little confused on what areas i need to research.

What i am trying to do is save text from a number of text boxes to a user named file then subsequently be able to reload the data back into the same text boxes at a later date.so far i have this which was provided for elsewhere on the web, this allows me to save comma delineated data to a file which is fine but i can't seem to reload the data. As an experiment i have just tried to reload it back into a rich text box to see if the process would work but nothing as yet.
Private Sub SAveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SAveToolStripMenuItem.Click
Dim savedfile As String
savedfile = TextBoxinc1.Text & "," & TextBoxinc2.Text & ","

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?

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
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 am currently working on an existing Windows Forms application (VB.net), and am busy reworking the exception handling mechanism.Currently, a lot of methods in the code are just surrounded with try/catch block that catches a generic exception and then calls a utility method that just shows the user a messagebox informing him of the error, and then logging it.So in a lot of cases no corrective action is taken and the exception is just logged. I know this probably isn't the best way but that's they way we're gonna have to do it for the near future.Anyway, I wanted to do this in a more generic way, so I hooked up Application.ThreadException and AppDomain.UnhandledException.
This seems to work well, except for one inconvenience. Whenever an error gets thrown from the .net runtime itself, or a 3rd party control, the stacktrace begins there where the exception is thrown in the framework-methods or 3rd party methods (obviously!)But it would be handier if I had an easy way of finding out exactly where these exceptions cross the boundary into my code. I would like an easy way of determining (in Application.ThreadException) where in my own code an exception originated. am aware this information is contained in the Exception.StackTrace property, but I would like an easy way to get to this specific information seeing as the stacktrace property is one huge string.

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)

I need to to able to save multiple text-boxes and a combo-box to a text file. the thing is, when I go to save, I check out the .txt file manually and its saved all in one line, no spaces. when I go to "read" it with the 2nd part (<-----this is a 2 part Challenge) it even reads all from that one line in the text file. What i'm asking is how can I make my text-boxes saved in the text file on different lines. [Code]

I am starting out in Visual Basic.Net and need a bit of assistance.I am creating a Windows form (not controls).In this program, I am attempting to validate 2 different text boxes BEFORE the rest of the controls can be validated. For example:I have an authorTextBox and titleTextBox, which the authorTextBox MUST have some user input BEFORE the user is permitted to move onto the titleTextBox. (the user input can be fake like "John Doe", the point is to force the user to input something).The instructions that I was given is not very clear on how to code this properly in order to have the form show an error message requiring the user to input something in both textboxes before they are permitted to move onto the other controls.

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
