Windows Form Closing Automatically When Parent Window Gets Focus?
Jan 24, 2012
VB Windows form Application.. I am developing an application of which part of the program is around configuration settings allowing the user to enter configuration items. When the menubar item for configuration menu is clicked on the main form the menu opens.This is fine but the mainform should not become active again until the configuration menu has closed. This does not happen right now and the mainform simply comes to the foreground and the configuration form goes to the background... I realize that coding an event on the Child form to handle this would not work because the child window loses control and the main form gains control.. I thought of coding a function as follows on the main form but it does not seem logical because i would have to add to it for everyform and do checking to make sure the child is actually open before trying to close it..
Private Sub Form1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.GotFocus
MailSettingsWindow.Close()
RentalSettingsWindow.Close()
[code]....
I did away with the above sub routine and used the below code as per the recomendation of using showdialog which works just as i was looking for.
Private Sub MailingAndEmailSettingsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MailingAndEmailSettingsToolStripMenuItem.Click
Dim MailConfig As New MailSettingsWindow()
MailSettingsWindow.Showdialog()
End Sub
I am having form called Test1 which contains button( Button1). When I press the button the message box is getting displaying,but at the same time I am accessing the Form Test1. It should not be the case, because before closing the message box the control should not allow to focus the Test1. But in my case the control is allowing to focus the Test1(form) before closing the message box.
Sample code.
If myReader.Read() Then MsgBox("Matched record exist.", MsgBoxStyle.Information, "Data Tool") Else
In my project i have one parent window form with one menu bar and one status bar. that is what i want is:when i show the child form to see in the status ber an icon relative to the child window.How i can do that?And if that can't be how i can see an icon in a task bar?
I have the following code to close a form which is a child. The problem is that when it closes, it closes the MDI parent too.
Private Sub frmTransaction_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing If ListView1.Items.Count >= 1 Then
I am making an address book for my final project in school, and have a few questions. In my address book, there is a feature to add groups so you can sort your contacts. The problem is, the add group feature is in a different form, I tried calling a procedure from the parent form to refresh all data but it does not work.[code]
How will i close all the forms within my main form? Everytime I click on the menus of my main form,I'm setting my main form as MDI-Parent form and then loading a new form as it it is the child form if I'm not mistaken. I have a log-out menu, and what I want to happen is everytime I log-out all the forms within my parent form will be closed. How will I do it? Here are some of my codes.
I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.
i have a parent form which is having a grid view. In the KeyDown event of the grid view i am calling a child form. If the user closed the child form, my application should close both the parent form and child form. What i have done is, i declared a boolean in the child form and passed the boolean value to parent. May be the code below will give the picture of what i am trying to do.
Private Sub gvJournalEntryDet_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles gvJournalEntryDet.KeyDown
how to set either a focus window or active window or something, but still able to move around in other windows with out my SendKeys function sending keys to any other window. This is the code I have to set the active window to the window I need to sendkeys to:
Dim targetWnd As Long = FindWindow("ncrwgst1.wal-mart.com - PuTTY", vbNullString) SetActiveWindow(targetWnd) Timer1.Start()
Now anytime I have like notepad or even my Remedy window up, it sends the keys to that window. how to set it where it JUST sends to the targethWnd I have defined and still move around in my other windows?
how to prevent a popup toolbox window (Form) from stealing the parent Form's focus?I've been told to override CreateParams and use WS_EX_NOACTIVATE (0x08000000) but that does not seem to work (see the code segment shown below). I'm using Show() and not ShowDialog().
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams Get Dim cp As CreateParams = MyBase.CreateParams
How can I ensure that the currently selected row ID in Parent Table automatically appears in my child form when I create a new row in the Child Form.I am using VB 2008 Express I have a Stored Procedure for the chiled table called "Files" can I do it from there:-
ALTER PROCEDURE dbo.CreateFile ( @FileName varchar(50), @DateCreated varchar(50),
have a main form that displays a users score.I hide the main form when going to a child form.When that child form is closed, it will show the main form.The problem is that the datathat has been changed when going to the child form is not displayed on the main form since it has not been closed.Is there anyway around this?
I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the paretn/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Serve,r I cannot create 2 separate datagrids from the same dataset.
I am migrating my code from vb.net 1.1 framework to vb.net 3.5In my windows application, the base window has some buttons and events are written for the same.I have shortcuts defined for these buttons also, for example: ctrl+d, DEL (keyboard) etc.Now i open a property Grid form on top of my base window for a selected object.Even when the focus is on this property grid, i am noticing that my base window events are firing on pressing those shortcuts.
example:I select some text in my property grid and hit delete button from keyboard. The delete event that i have written for the selected object gets fired and the text is not deleting.I fail to understand why is it happening. It wasnt behaving like this in .net 1.1.In .net 1.1 it would delete the text and only when the focus is back on the base window, hitting Delete would call the event.How do i control such a behavior? Is there some property that i need to set for property grid in .net 3.5 to prevent base window events from firing till the time focus is on property grid form?
i have created two forms A and B when button in form A is clicked B is invoked when B is running its not possible to work on A until i close form B. How can i work on A without closing B
Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.
I have an MDI form as the app start object.I don't think is related, but in the Form closing event, I check for some condition, and if it's true, I ask for confirmation before closing:
Private Sub FormBackground_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing If (e.CloseReason = CloseReason.UserClosing) Then[code].....
So long, everything works fine in my development machine, which runs windows XP.However, when deploying the application in a windows 7 machine, the message box works correctly, showing itself whenever it should, but after the form is closed the application keeps running in the background. This happens whether the form closes directly or asks the user first.I have fixed it putting an End instruction in the FormBackground.FormClosed event, but it doesn't feel good.
I am trying to pop up a window on clicking of the link within datagrid and passing textbox id with it. And on closing the popup window i want to set the value of the textbox control within datagrid need to be updated.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim strScript As String strScript = "<script>window.opener.document.forms(0)." + control.Value + ".value = '" strScript += "35"
[code]....
It works fine when the link is not within datagrid.
have been developing an application for quite some time now. I have decided to create an mdi parent form to hold all the windows I have done so far. Is there an easy way to implement the mdi parent/ child associations?
I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:
(in loginPage)
Public Event CloseApp As EventHandler Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click
If I show a new non-modal child window using .Show(frmParent), and then the parent window is minimized, the child will get minimized automatically as well.
I am working on a .NET console app which needs to clean up resources on exit. The problem I'm running into is that I don't get any notification if the cmd parent is closed via the console window [X], via Task Manager/Process Explorer or programmatically with WM_CLOSE. I can live with not being able to handle Kill Process from Task Mgr. or ProcExp. WM_CLOSE of the parent console is the most likely way that this application will be closed before it's finished processing.
Here are the events I've tried to register for so far: AppDomain.CurrentDomain.ProcessExit += CurrentDomainProcessExit; AppDomain.CurrentDomain.UnhandledException += CurrentDomainUnhandledException; Console.CancelKeyPress += ConsoleCancelKeyPress; Application.ApplicationExit += ApplicationApplicationExit; [Code] .....
These events fire properly when I send a CTRL+C from the console or the application finishes uninterrupted. But none of them fire when the parent app (cmd console) is closed. (The parent/grandparent processes aren't CLR so I'm not sure I would ever receive those Disposed/Exited events. Those are just shots in the dark.) I've looked at some pInvoke stuff but I would rather not go down that road if .NET is an option. Is there a way to detect and handle a shutdown in these situations? I am open to any .NET, pInvoke/Win32/C/C++ solution. (Basically any way it can be done on the Windows platform.). I'm still working with .NET 2.0 so I can't use anything introduced in .NET 3.0+
I have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.
I have a Visual Basic .Net form (launches after the splash screen tests database connectivity) and it is not focusing above other existing windows on launch. How do I get it to focus above all existing windows and Windows Explorer windows?
Is there a way to automatically resize a windows form to fit a smaller display? I created a program on a computer with a 12" display, everything works fine. However, when I load the same program on a computer with a 8" display, I am not able to view all the contents on the windows form. Is there a way to correct this without manually resizing all the contents on the form?
