I have an MDI web browser and it would be handy if it could save the open MDI childs at shut-down so that the next time the user would open the web browser the MDI childs would be still there...
Is that even possible?Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?

View 2 RepliesI'd take both C# and VB.NET suggestion.I'm using LINQ to query data. I'm trying to query the parent and count the child tags.Here's my Tags table column:
TagId (int primary)
TagName
ParentId (int Allow NULL referred to TagId column)
Here's some sample data:

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata
Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this
Protected Friend frmMain as Mainform
frmmain = new mainform
In frmMain I am doing this
Protected Friend frmsub as new Subform'

I've got a small reminder application I wrote in VB Express 2008. The main app autostarts with Windows and sits in the system tray all the time. Now, I need to save the time (sorta timestamp) it closes/terminates to a file. It works fine when the app is terminated by myself but doesn't when when I shutdown/reboot Windows. The code that saves the timestamp to a file resides in FormClosing event. But for some reason it doesn't fire or the code to save the file doesn't get executed when I shut down/reboot windows.
Is there a way, probably thru' Win API to register my app with Windows, so that windows actually waits for my app to terminate in a sane way after saving the data. I remember of reading about this possibility somewhere, I don't remember now.
I am wanting to find out how to use the Win32 hooks to allow me to add extra save locations to the save and open dialog box so as to allow as an option for files to be saved directly to a database rather than a file system.I have tried looking online but can't find anything remotely usable for this, the only data on hooks that I can find involves Window operation hooks, mouse, leyboard, and shell hooks, nothing to do with files.

I have created a (kind of) 'Desktop' Form for the main basis of my program. Basically it is made up of 3 panel controls.
1. Holds all buttons which load the different forms (Like the windows start menu when expanded). name: StartMenuPanel
2. Holds Information on log in deatails. name: LogCheckPanel (very thin panel at top of screen)
3. Main panel which takes up the majority of the screen (where I want the forms to load). name: MainPanel
My aim is: When a button is clicked from the 'StartMenuPanel' the form will load with-in the 'MainPanel'.
I tried changing the start position to 'centre parent', but the panels are in the way so some of the childform is overlayed by the panels.

When I run this I get the following error: 'Top-level control cannot be added to a control'.
I hope I've explained this well enough.
I set up some application settings for checkboxes on an app and then decided to remove them. When I set the Application Settings to (none) in the designer and restarted the app, the checkbox constantly checks and unchecks itself. I completely remade the app and removed the file that is used to store my.settings in the Local folder of the user's appdata profile. I also made sure to uncheck the "save my.settings" on shutdown.
View 6 RepliesIn WPF, I have a Uniform Grid and would like to be able to find the row and column based on the index of a child element.
I know there is a mathematical way of doing this and would rather not use a normal Grid.

View 1 RepliesI have a date selector on mdi parent that updates a property when date is changed. When I open a child form, it grabs the property just fine. However if I change the date again after the child is open the date does not change on the child unless I close and reopen the form as expected. What would be the best way to automatically update all open child forms when the date is changed on the parent at anytime? running a timer to parse the date property is impractical.

The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".
disable the parent window form as soon as the user will open the child form....
for eg...consider daniweb...when we click on member login the background form gets grayed out....
Disabling the form is not the option cause it will just disable all the controls of the form....but I need a grayed out screen between the current child form and the parent form....
note - the parent form is not the MDI form...it is just a normal window form and when the child form is open and if the user clicks on the main form without closing the child form then the screen should show some movement...
I tried disabling the form...changing the background of the form to opaque....but could not get through it....
