in Form1, I have this code
Dim FormTwo As New Form2
FormTwo.ShowDialog()
Close()[code].....
if I use Application.Exit, it will close all 3 forms.. But all I want to use is Close so that every time I show the Form2, it will close the Form1 first.. the same when I show the Form3, it will close the Form2 first.
I am having a problem with the form. I want to make that if the form2 close, the form1 will be shown. I've tryed this code but it doesn't work.
If me.close then
form1.show

View 2 RepliesI have 3 forms 1 -mainform which loads when program is open, and where you select the datafile you want to use and input default information in about 20 textboxes 2 butons 1 to each page 2 -has 3 comboboxes and about 20 textboxes worth of information pulled from the database. then 20 textboxes the user can enter values to compare against the default values coming from form1. and 20 boxes that have calculation results 2 buttons one to each page 3 -same as form2
I created a textbox font format function in form 3
When I load program and click button for form3 everything works fine, i can then click button to take me to form2 and vice versa back and forth no problem
When I load program and click button to form2 I get a date casting error from the function on form 3
Why would I even get this if i havent shown form3 yet??
IThere's a button on the toolstip that's always enabled for form2 so they are always able to search the database.When a user is on form1 and selects the link button. They are taken to form2 to select criteria to search. On Form3 they choose 1 item in the grid andcan select the Link It button on the form to link the 2 selected grid items (form1 and form3). Since form2 and form3 are available at anytime.my problem is knowing when the Link button on form1 has been chosen and after a successful link to not allow anymore links. Technically, they could pull form2 up via the toolstrip or an existing form2 window and Link as long as Form1 is on the screen but I do not want this. It's as though I need a global variable to set to True/False.
View 1 RepliesLast one day I could not manage to pass data from one form2 other form.
When I am opening Form2 from Form1, I can pass data from Form1 to Form2.
When I am closing Form2, I want to pass data from Form2 to Form1 which is still open when I close form2.
I try to use shared textbox, but I understand that this is nt supported.
I am creating a VB program that has a Main class, and 4 windows forms. Each of the forms has a back and a next button to navigate trough the forms. The problem is that when I hit next (Here is the code)
Private Sub continueButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles continueButton.Click
VS 2008 Remember Textbox Text when Form reopens
I have got 2 forms ----- form1 and form2
i wanted to navigate from form1 to form2. and then close form1
i did the following code.
-sub form1 _ page load
dim form as new form2

-end sub
i also tried -- form1.close() and form1.dispose() but all in vain
Problem is that my form1 is not getting closed
I am creating a Pizza Order program as part of my coursework college. why something isn't working.
Quote:
lblTotal.Text = Val(Form2.lblPizzaTotal.Text) + Val(Form3.lblDrinksTotal.Text)
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.
I started to create the MathQuiz and it is working good as per the provide codes. I was also able to add 'Percentage Correct Answers' and some other details.I have added a new form with some buttons and that is working as well, just simple stuff and all good fun playing with it.
But here is my challenge:When 1 or more answers are incorrect the program is opening a new form (similar to the main form) and it shows the equations again. I did that with "Correcting.lblLADD.Text = addend1", etc. in then main form. In the form 'Correcting' = Form3.Designer.vb I have tried to get the Text into a Number but nothing works for me. Also Tried to make addend1 in Form1 Public but the value does not appear in Form3. Form3 has also a Private addend1 as Integer.Even if I give addend1 in Form3 a value Form3 does not calculate.Maybe it does but I can get it to work. I have tried to get a MessageBox to show up when the answer in Form3 is correct but the MessageBox does not work either.

I'm trying to use checkboxes to show and close child forms.I'm using MDI. I want to try and make the child form show inside of the parent form like it should.This is the code I was using:
[code]...
And that works, but if I close the window instead of using the check box and then try to use the checkbox to open the new window again i get an error:Object reference not set to an instance of an object.Also I have more than one checkbox (each one serves a child form) and I would like to be able to open and close any of the child forms at any time.
Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show()
Me.Close()
End Sub
i have this code on my MDI parent and on button click i would like Parent to close and form2 to load/show.yet with current code when i click button it closes all the app and doesnt load from2
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?
View 30 RepliesI made 2 form.
In form1 I have this:
form2.show()
form2 ends up behind form1, how can I make form2 appear in front of form1?
Form2.showdialog() will make form1 disappear until form2 is closed, that is not what I want.
I have two forms on my project and I want to be able to click a button and have the other form appear and show a picture in a picture box.
View 1 RepliesI am using vb 2008,First Opening MDI Form, then Opening Children, Normally Close command, is working clean, that is ok. For my Climate, opening three children, after close all, MDI form is not closing, even after dispose command was given.
There is no error showing..!, everything going, clean exit., but only MDI form is not closing..?What may be a problem, it is different...? I do not know where was the problem, problem is vb 2008.
I am a rookie in VB and have been trying to show in form2 only the records in table2 filtered by the value of a textbox shown in form1 which is a value from table1.So far I have not been able to achieve this and I have seen so many answers to similar questions but when I try there is always something wrong.
View 2 RepliesIn a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

I made a Vista Aero -style form for XP, but when using it, the application won't close. The FormClosed and Disposed events fire, but not the HandleDestroyed event. I tried to get around that by handling the Disposed event and calling Me.DestroyHandle(), and it worked, but not if the user resized the form so that it caused an IndexOutOfRangeException in BlurImage().The code is attached.
View 2 RepliesI have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.

Suppose, i have a button(button1)in form1.
Now i have opened a new form.
I want to display the same button(button1) from form1 to form2.
If I create a new form, say Form2, in order to use it in a program I must create an instance of it: Dim frmTwo and new Form2, If Form2 has a text box on it I can put this code in Form1: [Code] But what happens if I want to refer to an object (a text box)in Form1 with code in frmTwo? This doesn't work: [Code] How is the instance of Form1 created? And How do I refer to it?
