View 1 RepliesI am having trouble catching getting the currently active text input on a 3rd party window.
If I use GetForegroundWindow it returns the handle of the main process of that window.
When I have two MDI Child forms opened, it is difficult to visually see the active form versus the non-active form.I would like to have the Active Form stand out more, say a yellow border.
View 3 RepliesI'm from denmark and hope I can explain my question for you. This is just a example: I have a panel, let's say panel1 and another panel on that panel (panel2) and so on until for example panel5 - on panel5 I have a button (button1). Now I would like to change button1's backcolor property through code how do I then get access to button1, now it's a child-control on panel5 that is a child control on panel4 etc. ??

View 3 RepliesIt 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 UserControl that contains other controls that I would like to be able to rearrange or resize at design time. So I have a custom designer for the UserControl that inherits from System.Windows.Forms.Design.ParentControlDesigner, and I call EnableDesignMode on the child controls from within the designer. That way, at design time, I can drag and drop the child controls to move them, or resize them. But I can also drag and drop the child controls somewhere else on the form that is outside of the original UserControl. Is there a way I can limit the child controls from being moved or resized outside the UserControl?

I am using Visual Basic .Net 2005 professional.From what I understand, I should be disposing of any object that is an unmanaged resource. I understand the best way to tell if a resource is unmanaged is if it has a Dispose method. ie: If I type a dot after my object, intellisense shows .Dispose() as one of the options. If it does, it's an unmanaged resource. Is that correct? In that case, pretty much every control is an unmanaged resource: buttons, forms, panels, etc.In the application I am working on I use an MDIparent container form, which contains MDI children forms, which themselves contain Panels, Menus, Groupboxes, etc, which in turn contain Buttons, Textboxes, Labels, Dropdowns, etc.Do I have to dispose of each button, textbox, label and dropdown within a panel before disposing of the panel?
Do I have to dispose of each panel, menu, and groupbox before disposing of the MDI child form?.Or can I just call the Dispose() method of the MDIchild form and the GarbageCollector will take care of all the controls and resources within the form?Watching the "mem usage" in Windows Task Manager seems to be an unreliable way to detect if I have a memory leak. The numbers just keep climbing and falling (mostly climbing) erratically and without any activity performed on the application. Is there some (relatively) easy way to detect leaks?

I wanted to create some CLR functions that will access Active Directory, but I discovered I can't add a reference to "System.DirectoryServices" to my CLR project.
I googled it, and found that I have to add the AD dll as an Assembly to the SQL Server. Like so:
CREATE ASSEMBLY [System.DirectoryServices]
FROM 'C:WindowsMicrosoft.NETFrameworkv2.0.50727System.DirectoryServices.dll'
WITH PERMISSION_SET = UNSAFE
GO
The problem here is that I have to set the "PERMISSION_SET = UNSAFE" to the dll... this means that I have to set the database as "TRUSTWORTHY ON", and this opens a can a worms!
