VS 2010 MDI Child Form Focus?
Jul 22, 2011
I have MDI application and couple of child windows...This is how I'm opening one child window
Private Sub Membe*******tripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles Membe*******tripMenuItem.Click
Dim members As New members
members.MdiParent = Me
[code]....
My problem is that I dont have an idea how to check is that form already opened and if it is simply to focus it... Now I can open as many as I want same forms (on the picture this are couple same child forms, what I don't want...So I need simple check is this child form opened and if yes focus it?

I have a borderless form displayed as a progress object. This is displayed via childform.show().
I'm overriding CS_DROPSHADOW to give it the shadow (pictured), when the form loses focus (parent clicked or another formapplication) the shadow is lost.
How can I keep the form focusedselected similar to a modal form? (I cannot use showdialog due this being called from various threads other than UI) Using Me.TopMost = True works, but obviously puts the form above all others rather than just the parent.

We have a main form which opens an MDI child form. What we want is to set the focus on a particular control in the child form, namely a telerik textbox. When the form is opened for the first time, the focus is set to the textbox control which has a tabIndex = 1 as expected. If the winodw is closed (and disposed) and then reopened via a button on the tool bar that calls the same code that opens the window when the application starts, no control has focus. We have added lines such as Me.rtxtPatientId.Focus() in the Paint event, load event, and activated event handlers but still cannot get the focus to the control. The code is quite extensive so posting it is difficult. However, here is the section that opens the child window:
if PatientSearchForm Is Nothing Then
PatientSearchForm = New frmPatientLookup
End If
PatientSearchForm.MdiParent = Me
PatientSearchForm.Show()
If PatientSearchForm.WindowState = FormWindowState.Minimized Then
PatientSearchForm.WindowState = FormWindowState.Normal
End If
PatientSearchForm.Activate()
PatientSearchForm.rtxtPatientID.Focus()

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.

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 an application that just stores shortcuts to most used applications on users desktops. My problem is that when the machine loads after they login the app window looses focus and sometimes doesn't show in the taskbar. I tried to use Me.Focus() but that just gives the treeview focus and not the form itself. I mean the parent has focus in the treeview but the form is not highlighted, I can then click on the form and it gets selected.
What is a good way to get the whole form focus? I used me.focus in the form load too.

This is the code so far I have been testing for my MDI Parent/Child forms, and when I create for example 2 child forms with the File - > New menu option, the Windows menu lists all the forms I have just created ammended to it. Now when I create the 2 forms and then immediately select Rename under the Windows menu option, it changes the text of the last child form ok, but then if I click on the first child form that was create and then hit Rename again it doesnt do anything. I tried different methods of strying to set which forms has focux but nothing works.

I want to prevent my application from losing focus, untill I close it. (so that I can not click on ANYTHING else, untill I'm done with it. period.)I've tried using Me.Focus() on a timer, but that doesn't do s***...I've also tried countless API's out there, but I seriously can't get any of them to work.. my form simply does NOT want to stay in focus! It's driving me crazy! What the hell am I doing wrong?

I want to make a form the topmost form, but without giving it focus.Alternatively, I could check which window has focus, display my form, then give the original window focus again?

We've migrated the application from VB 6.0 to VB.Net If more than one MDI child form is open, a mouse click to an inactive form will not bring it to front unless I click on the Tiltlebar.

I have achieved for the most part what the users want, which is to be able to have multiple MDIChild forms open at once for example the Child form displaying the data and the Child form displaying the user's manual. The child forms can be resized to some extent and can be moved around within the Parent form. When the user clicks on the title bar of one of the Child forms or selects a menu item opening a new Child form the newly opened Child form or the Child form on which the user has clicked the title bar gets focus.
I also have one Child form which will not scroll with the mouse wheel even when it has focus. Actually there is very little of the form that is not ocvered with controls. It has about 8 group boxes with several otehr controls within the group boxes. When I click on a list box within one of the group boxes the list box will scroll through the values, but when some other control gets the focus or the forms itself has focus (via clicking on the form's title bar)the form will not scroll with the mouse wheel. The other Child forms do scroll with the mouse wheel.The AutoScroll and AutoSize properties of the Child form are both set to true. I also have VerticalScroll and HorizontalScroll visible and enabled properties sey to true

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 parent/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 Server I cannot create 2 separate datagrids from the same dataset.

I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".

A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.
