Write Text From A Parent Form To The Active Mdi Child Form VB 2010
Jan 28, 2012It 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.

View 4 RepliesTimer Control On Child Form Crashes VS 2010?
Sep 7, 2011I'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?

View 1 RepliesHow To Find Name Of Active Control On Form
Mar 12, 2009I'm an old Access developer and know VBA quite well, but now I'm working at learning VB.net. I'm trying to find the equivilent of the following Access VBA code using VB.net:
Function EvalField()
Dim x As Integer, ctl As Control
Set ctl = Screen.ActiveControl
x = Val(Mid(ctl.Name, 5))
Screen.ActiveForm.Controls("Formula" & x) = ctl
ctl = Eval(ctl)
UpdateTotal
End Function
This code sets a control variable to the currently active control, then copies the text from that control into it's matching "Formula" field for reference by the user), then turns the string of math into the answer. For example, if the user enters 5 + 4, that will be copied to the Formula textbox, then it will be evaluated and the answer will replace the 5 + 4. And lastly, the UpdateTotal sub will execute which will add this answer to the existing Total field.

Forms :: Skip Validation Of Active Control When Form's Close Button Is Clicked
Aug 12, 2009Is 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.
View 5 RepliesReference A Control On Parent Form From Child?
Oct 7, 2008Using MDI in .net, how do you reference a control on a parent form from a child? Like, if on the parent I have a textbox called txtBox1, what could I do from the child form to read the contents? I've been googling unsuccessfully all day. The closest I've found is
Parent!ControlName.Property
I don't know what the ! is supposed to mean, but I get an error here: Class 'System.Windows.Forms.Control' cannot be indexed because it has no default property.
Set Focus On Particular Control When Opening Child Form
May 12, 2011We 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()

View 10 RepliesVS 2010 Child Form Tell Parent Form It Is Closing And Send ID?
Apr 2, 2012I 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.
C# - Detecting The Form Move Event From Within A Child Control?
Jul 8, 2010I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.

Aug 18, 2009I want to include the clipboard from the menu strip of my MDI form, ie Cntrl/C and Cntrl/V. I need a more generic clipboard facility than the examples provided. I want to be able to copy from external programs, like Word, or controls within my program to either a Textbox, RichTextBox or whatever, of which there may be several, on a child form. In VB6 this was so simple, but I'm afraid it is proving frustrating, to say the least, in Visual Studio 2008. I have succeeded in getting data onto the clipboard from an external program, but my problem comes when trying to determine the active control on the child form to where I want to paste the data, so I know how to handle it.
