Been searching the web for about an hour now and not having a lot of luck. Got my MDI Parent with some buttons on and one of the buttons I want to hide all open MDI Children forms but I don't want to close them.
View 2 RepliesI 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'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'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 have three forms: A, B and C. Upon a button being clicked, A displays B. Similarly, B displays C. Both using the ShowDialog() method.
However when I use the Hide() method (inside a Button Click event) on form C to close it, form B also closes. Why would this be? As far as I can see, it shouldn't be doing this. I certainly didn't write any code to tell it to do that.

UPDATE: I am an idiot. DialogResult was set to Cancel on the button as I'd copy+pasted it from the existing Close button and not realised that property was set
I am working on a project and now I need to know how to have checkboxes on children nodes and not on parent nodes.
View 5 RepliesI use a splitcontainer in my programme, along with a couple of mdi-childs. I've got a problem now: The splitcontainer is actually in my main form, which is a mdi-container itself. Whenever I try to use mdi-childs, the panel of the splitcontainer is in front of it. Also I have problems with docking the mdi-child into the panel of the splitcontainer.

In 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.
If it helps, I can get the total number of rows and columns by using:
Math.Sqrt([*uniformgrid*].Children.Count)
This is a challenging one that got me stumped while I was coding today. Suppose I am running the Sub Test1() and Test2() and would like to print out the value of the Shadows method of the instance of the object I am passing in to TestCall() (see below - it is clearer) using the following restrictions:
Can't change the contents of Class A, B, and C
Can't change Sub Test1() and Sub Test2()
TestCall() can't have an if, select case etc. statement that tries to figure out the type

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

I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

View 1 RepliesI am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.

I have four children in a parent container. Each child form is a test for the user to type correct answers into text boxes. Option to open each form is on a menu strip in the parent. In form load, I have disabled all but the first form option. I only want the second form to become available if the first form answers are correct. I would like to figure this out on my own as much as possible. I have searched on line but since I am not sure what to ask, I have not found and answer. Can someone get me started in the right direction? Perhaps some reading that would explain how to go about this, or what I should be typing into google to get what I'm looking for.

I was thinking maybe with an uncommon filesystem, but then I 'd probably have to implement the IO myself, which sounds like a huge work.Another idea would be to access the disk sectors in a low level way and store data in an incompatible way?
