I have a collection similar to:
Public Class MyCollection
Inherits ObservableCollection(Of MyCollection)
Private _Name As String
[code]....
EDIT: I know that I can use DebuggerDisplay, but unfortunately it is very limited. The class in reality is quite complex and I need to have the possibility to define a logic in what I show during debugging, if possible.
I have made some changes in my code but when i do debug it doesn't show the changes.For example: In my code i create a simple text file in "C" drive.I have change the path to the desktop and when i do debug it still create it in the "C" drive.

View 3 RepliesI'm writing a Windows Service:
Code:
Public Class Service1
Protected Overrides Sub OnStart(ByVal args() As String)
System.Diagnostics.Debugger.Break()
[Code].....
I've installed the service, I can run it with no errors but... I can't debug!
I thought that with the line System.Diagnostics.Debugger.Break()
the service should stop and wait for my input. But NO!
I also tried to click on Tools > Attach process to debug but I can't see anything, just a gray background!
In the registry event it's written that the process started successfully, but the process doesn't show me the message box "Up and running"
I have the Immediate window option available in my menu, but when I click it or do the keyboard shortcut, nothing happens. It's quite difficult to debug an application without an Immediate window.I've tried resetting my settings to general developer and all of the other suggestions I found on the web, but still, no immediate window shows up when I click it or do the keyboard shortcuts..

How do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?

[Code]....
when people first run my program (as in the FIRST EVER time they run it), I want a window to popup (Form4). In this Form you have to locate a directory to a certain program (my program uses this program) and press OK, and then that will generate a .txt file with the directory to the program. (So that my program knows where that program is located.) Now, what I want it to do is when you open up the program, upon load (Form1), I want the program to check if that text file (directory.txt) exists. If it does and the path in the file is correct, the program will run fine. If the text file is missing and/or the directory doesn't exist, it will bring you back to Form4 (assuming that this is your first time running the program since the directory.txt file doesn't exist).

When I launch VB Help and do a search it shows under "Local Help", "Exception from HRESULT:0x8004032E". It lists three results under "MSDN Online", but the large field to the left of it is entirely blank. If I double-click blindly in that blank area it brings up various topics as if they were listed there but invisible. Further, the region under "Contents" is also blank, as is the "Filter by:" field. If I click the down arrow by the "Filter by:" field it brings up an entirely blank menu. If I then click outside the menu box it brings up a message saying "The selected filter contains an error that prevents it from being applied.". What's wrong and how can I fix it?
