VB2008 : Clear All The Input And Reset To The Beginning When The Program Is Just Opened?
Oct 7, 2010
I have built up an interface in VB2008 with many textboxs and labels on. When I click "New", I would like to clear all the textboxs and labels, i.e. each with a NULL value. Meanwhile, I also would like to clear all the arrays behind the program, i.e. the arrays which are not shown on the interface but is important for the calculation.The only way I could find out now is to clear the textboxs, labels and arrays one by one. So if there are 100 textboxs, 100 arrays, I have to write 200 lines in total. Obviously, it is not expected. Is there any other quick ways to directly reset everything to the beginning when the interface is just opened?

I got on my form textboxes, checboxes but also a groupbox which holds texboxes.
The idea is to be able to clear and reset all of these by clicking a reset button.
At the moment i got this
Private Sub ClearFields()
Dim ctrl As Control
[Code].....
But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.

Is there an easy way to reset or clear a DataReader so it can be read through more than one time? I found a Close method but not an open method.

I currently have a chart that plots lines of a changing value every time it is called via a timer.
Everything is running as I expected and I am happy, but now I want to be able to press a [STOP] button which will stop the timer and stop the graph from updating, (which I have coded and is now working OK), BUT I then want the code under this [STOP] button to clear everything from the graph, so when I re-start the timer, the graph is cleared and starts plotting fresh points on a clean graph.
The problem I currently have is that when I press the [STOP] button and then press the [START] button, the new lines that get plotted are "added" to the existing lines that are already on the chart, instead of having a new "blank" chart, with no data on it.
So what I am really asking is does anyone know if it is possible to reset a chart clearing everything off it so it is ready to start displaying fresh data?
I was hoping it was something like: "Chart1.Clear" or something simple like that, but I can't seem to find anything that will do it.

I have the following line of code used to input the name of a text file to be opened and during development this was working without a problem. However when I create an executable this is not working and I was hoping someone would be able to give me a tip on resolving this matter.
Dim fileName As String = Application.StartupPath & "" & TextBox1.Text

I am using a datagridview as an input screen for repetitive inputs of a similar nature. Once I have saved the data, is it possible to clear the input in the grid for the next round of inputs. At present, all I seem to be able to do is clear all the rows and then create a new set of rows.

Imports System.Net
Imports System.Net.Mail
Public Class Form1
Sub sendMail()
Try
Dim AnEmailMessage As New MailMessage
[Code]...
I use this code to send an email through gmail account but the thing I want to do is, I want to check whether the given email and password exists or not and if it exists then pop out a text box with the body of the mail and type the text and then send it as a mail. But in the above code you have to log in and type body and when you send the mail , It verifies for the email and password while sending and if anything goes wrong says there is no such gmail account.but i want to check it whether the email and password exists or not, when the user enters the email and password at the beginning itself.So that he enters the right email to log on to compose a mail.Is there any way to check whether the given email and password is correct at the beginning only ?

I have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.

I'm launching an Access ADE, using Tony Toews auto FE program. The AutoFE programs will, if newer version available, copy the latest version of the ADE from the server, then launch it. My code looks like:
Dim stAutoFE As String = "V:Appsautofestartmdb.exe /cmd /inifile: " & """" & "V:AppsAutoFESSP.ini" & """"
Shell(stAutoFE, AppWinStyle.Hide, True)
System.Threading.Thread.Sleep(1000) ' Time delay
[code]....
I had to put the Sleep delay in, otherwise the GetObject would open the ADE a second time.But I don't know how long the copy from the server will take, so I need to remove that Sleep line and check that the ADE has opened.

I'm using Visual Studio 2008 and developing a VB.NET application. I'm having strange lockup problems with my program, but only when Internet explorer 8 is opened.
When I cover my form with another window and then uncover it, I find that it has locked up. My program has no references to IE and the only thing it even has to do with IE is using Process.Start with a web address.
My program works fine and exactly as it should, but only when IE is not opened.
Does anyone know why a program would lock up only while IE is running?
Edit: I've done some digging and I've found the offending thread in my program.
I don't know what starts this thread or what it does, but when I kill it, my program no longer freezes. The thread is one of the CreateApplicationContext threads, here is the last few items in the stack trace of that thread.

This always happens to me in Visual Basic. Whenever I save a project from one day and open it again using that same VB version the next day, I can never see the form design. But if I click on Debug, I can see the Form design and only use it as if it were a program.

I am Matthew and I'm extremely new to coding and any sort of scripting language; yet I am highly interested in programming and want to learn lots about this subject. So to start myself off I am trying to create some applications which I could use in day-to-day life to just basically make life easier.So the first program I am trying to make I am already confused and not sure what the heck I have to do in order to get it functioning, I've looked on lots of videos on you tube for tutorials and they have all done a great job but some videos just don't answer my questions.When I click a button and "Form2.Show()" appears, how can I make it so that when I type text in a list box in form2, it doesn't disappear when I close it? Then once I have known done that, how can I make it so I can choose a random string of text in the list box on form2 to show up on the click of a button on form1? Then a final question is, How do I prevent fields being reset in form1 & form2 on program close? Also, is it ok for me to make a thread asking 1 simple question? or do I have to ask a handful each time to save threads or something?

I am currently working on a program that has several buttons in it lined up. Each button goes to different applications (.exe programs). The program I am making is suppose to be a fullscreen program and won't let you see any of Windows when it's running.
Therefore I want to make a "back" button that always stays on top of any application and when I push it it will take me back to my WindowsForm (startpage of the program).I am also wondering if you can make it so all .exe programs only can run ONCE. So if I press one of the buttons saying "open notepad" I want it to work so it can't open Notepad once again making it two notepads open. Just go back to the first Notepad opened.

Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?
