VS 2010 How To Prevent Fields Being Reset In Form1 & Form2 On Program Close
Nov 18, 2011I 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?

View 7 RepliesName Change For Form1?
May 24, 2011I may have corrupted my Visual Studio Software. I have two problems which may be related. The first is when I open anew project, I can't change the name of the form. I enter frmXXXX and it returns a splash box indicating I may loose my programming. If I continue the program gives me an unusable form. This happens when I have not even begun to use the form. My Visual Studio is set up to work with Visual Basic only.
Secondly, when I try to incorporate events, I can not get them to function. Using the basic form set as Form1, the Load event will work, but it enters as "Private sub Form1_Load ........ Handles MyBase.Load not Me.Load. When I try to use the events: KeyPress. KeyDown Or KeyUp, I can't get them to function. They also are entered as ........ MyBase.KeyPress. To enter an event I go to the Properties Menu, and use the event enry, click on the function, then double click the function. The sub-routine is loaded into the program, but doesn't function. I am learning by using a text book that the same programming works in a demo which was downloaded.

View 1 RepliesCall One Form1 And The Other Settings?
Apr 1, 2010My program has two forms. Let's call one Form1 and the other Settings. It's possible that Settings may be opened before Form1. Settings may also change some settings that need to be updated immediately on Form1. The thing is, if Form1 hasn't been opened yet, certain elements haven't been fully initialized (even tho Form1's properties can be modified since I do create an instance of the form on program load). Since these elements haven't been initialized, if Settings tries to modify them, it crashes the program.
Are there any ideas how, maybe to keep Settings from modifying stuff on a form that hasn't been loaded yet for the first time.

View 5 RepliesClosing Form1 Save Enough?
May 25, 2009In my application I am using some sort of 'FirstRun Wizard' to make basic settings such as data path, theme settings and other adjustments before the application starts for the first time. I am using the following at Application Start to accomplish that:
If My.Settings.FirstStart = "1" Then
dlg_FirstRun.ShowDialog()
Me.Hide() 'Form1 - my main form
End If
Now, my "FirstRun" dialog has a Cancel Button and I want the application to exit entirely if that button is pressed. At first I used Application.Exit() but it looked a bit strange because my Form1 gets shown for a fraction of a second before the application closes. With Form1.Close() I can do the same thing and the advantage is that my form does not show up at all. However, I wonder if this is a save way of doing it?

View 1 RepliesForm1 To Open Form2?
Mar 27, 2009I have been converting my VB6 programmes to VB 2008, and I am beginning to regret it.According to the books that I am reading on the subject, I can call a second form from the first one. That is, when the first form code has completed, and the final line reads:
frmForm2.Show()
the second form should open and wait for input.This does not happen, the form flashes and then disappears without allowing any input, or button click.I must admit that I preferred being able to start from a module, with a Main() sub, which then read the forms, a la VB6. everything seemed to work fine then.
