MDIParent Button Click To Display MDIChild Form?
Jun 9, 2011I have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?
Private Sub btnExecutive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecutive.Click
Dim MDIChildForm As New frmExecutiveInfo

VS 2008 Form - 'Exit' Button - When User Clicks It, Another Form Is Displayed
Jun 2, 2012On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip
Multiple Forms - Declare And Instantiate Second Form On Program Start - Use Button Simply To Show Form?
Jan 14, 2010I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

Display A Windows Form BEFORE "Startup" Form Is Loaded In Program?
Dec 20, 2010My company's main software package includes a hefty configuration library which loads on startup. This config library includes some mandatory settings which, if not supplied (via command line arguments), cause the entire application to exit.
This has never been an issue for our users, who launch the software via scripts which have the needed command line arguments supplied automatically. But sometimes when debugging our software we developers forget to specify the necessary arguments in Visual Studio's debug options; it's then very annoying to be greeted with the message Config specification invalid -- missing required parameters X, Y, and Z -- shutting down (I'm paraphrasing, of course).[code]...

tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....

All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
