I just starting to use MDI form. I can show the child MDI form, without any problem. My problem is that I want to close the child form also from the parent menu bar. This is my code:
Private Sub CloseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseToolStripMenuItem.Click
Dim frmActive As Form = Me.ActivateMdiChild
[code].....
It has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.
I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.
Private
Sub OpenToolStripMenuItem_Click(ByVal sender
As System.Object,

I want to get the contents of the active child MDI form, how do you do that? Here's what I did to create a child form.
childForm += 1
If childForm > UBound(childForms) Then
ReDim childForms(childForm)
[Code].....
So say I want to get the text from an active form. How can I get the active form id so I can just do this?
childforms(childform).textbox1.text

View 7 RepliesI am using Visual Studio 2005. What I am trying to achieve is the following: I have a login form (form1) for the user. On successful login, a new form (form2) pops up which allows the user to add details of a student (name, age, address, courses taken, etc).
Following is what I tried to achieve the above said:
1) File>New>Project>VB Windows Application ................for form1
2) Project>Add Windows Form>Windows Form ...............for form2
What is happening is when I close form2, the application is not getting closed, form1 still exists. What i wish is that when I close any form (form1 or form2 or form3 etc ), the entire application must close.

View 2 RepliesIs there any way to skip a the validating event of the active control when the close button of the form is clicked. It is very annoying when user wants to close the form, but due to the validate event of the active control, it asks for the valid input. The user is forced to give valid input to close the form. I have searched a lot for this on net but no any proper solution could be found.

'In parent open the form when option is clicked
Public Sub Showfrmitemreview(ByVal sender As Object, ByVal e As EventArgs) Handles itemreivewStripMenuItemA.Click, itemreviewStripMenuItemB.Click
[Code]....
Nothing happens I don't even get an error message. I've played around with the code numerous times and the only thing that worked was to have it open outside of the parent which I do not want to happen.
what I want to do is cancel a MDI child form closing when the 'X' at the top right hand side of the form is clicked.So, I use e.Cancel = True in the MDIchild_FormClosing event.However, the parent will not close if the 'X' button is clicked, and I noticed that the FormClosing event of the child handles 'Me', which I assume is the parent.Changing the handles 'Me' to handles 'nameOfChildForm' only generates an error Error: Handles clause requires a WithEvents variable defined in the containing type or one of its base types

View 4 RepliesI am having trouble catching getting the currently active text input on a 3rd party window.
If I use GetForegroundWindow it returns the handle of the main process of that window.
I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.

View 7 RepliesI have been looking around at how I can close my parent form and my child form. This article: [URL] has some information but it either doesn't work for me or I am putting the wrong information it. What I want to happen is when a button is pressed I want to close both parent and child forms and then go to another form (frmResults). Then there will be a button on frmResults that will take me to the beginning form (frmPTCalculator). With this code below when I click the button on frmCalculator it goes to the MDI form and both parent and child forms are there.
my Parent form is called: frmGender
my Child form is call: frmMale & frmFemale
Below is what I have tried from the example in my Child form frmMale:
Private Sub btnResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResults.Click
Dim frm2 As frmMale = New frmMale()
AddHandler frm2.FormClosed, AddressOf frm2_FormClosed
