.net - Get A WPF Element To Respond To Changes In A VB Module?
Oct 8, 2010Objects whose Properties are observed for changes must implement the System.ComponentModel.INotifyPropertyChanged event to alert their WPF-element observers that a change has occurred.
If I have a Visual Basic Module whose Properties I wish to have observed by a WPF element, how should I go about routing the Properties of that Module through to the WPF, considering that Modules cannot, themselves, implement Interfaces?
EDIT: Modules are Static classes, for you C# readers, IIRC.
How To Respond To Msgbox YES/No Buttons

Continue On An Old Respond About System.IntPtr
Oct 18, 2010The idea with System.IntPtr is to represent an integer whose width in bits correspond to the size of a pointer in the hardware and operating system that the CLR is running in, it's platform specific in other words. It supports 32-bit and 64-bit architectures only.This is a legacy from old-style C API's where pointers and ints were frequently treated as interchangeable. The Win32 API has many such parameters, where the width varies with the underlying architecture thus the mess with porting of code from 32-bit to 64-bit (we already did this once when going from 16-bit to 32-bit, funny how we never learn...).In practice, as is mentioned in other responses, it can be used to hold unmanaged resource handles and pointers etc that stem from the underlying Win32 functions. It can also be used to hold integers of the natural size for current platform. You can also use IntPtr.Size to dtermine the size of a pointer on the current platform.SO when you explain this to a child ;) this would be used to let program's flow at the same speed at diffrent kinds of operating systems?

Jun 16, 2011I'm using VB.net to have a GUI on top of a commandline program.
[code]...
Which works and prints out all output from the commandline program. However at some point the commandline program ask for user interaction, eg: Type a number (1/2/3/4):But the commandline program stops after this. I suspect this is because it doesn't receive a valid option.Is there a way to capture when the commandline program wants user interaction and hold the reading of the stream to be able to enable the user to input something?

Respond To HTTP HEAD Requests Using ASP.NET?
Nov 24, 2011I have a server making a head request to a database dump I've created. The remote server does this to make sure that it's not using excessive bandwidth when not necessary.However, due to some other circumstances outside my control this causes the script to be hit twice: once for the head request, and then another time to download the data.
What I'd like is to have the script I've written detect the head request, send back a couple of headers (e.g. last modified is right now, filesize different than before), and exit. Is there a way to do this?

MainData in turn has a collection of a class, ProcessData, as a field and ProcessData has a collection of a class, Measurement, as a field. I.e.:

View 1 RepliesMake A VB Listbox To Respond Directly When The User Clicks On The Items?
Feb 20, 2006How do we make a visual basic listbox to respond directly when the user clicks on the items in the textbox? (such as making a menu appear or displaying info in a label when the items are clicked)
I have used the SelectedIndexChange event but nothing happens when the listbox items are clicked. The SelectedIndexChange event only seems to work when a button is added. It seems that the button's click event gets the listbox's selectedindex change event to start working. The listbox's textchanged event doesnt seem to work also.
Is there any way to make the listbox respond directly to the user's clicks without the use of button controls?
