TraceSwitch = 0 - Set To 0 Or Missing?
Jun 11, 2009
I have the code below that reads the partial app.config below. It works fine. But wondering how can I check that "value" is set to 0 or that the TraceSwitch is missing. If I remove the switches, my messagebox displays a 0. I want to display a user message if the app.config is not able to provide logging. And if the TraceLevel is set to 0, I will not show a message.
Dim s As New System.Diagnostics.TraceSwitch("TraceLevel", "")
MessageBox.Show("Trace Level: " & s.Level)
<system.diagnostics>

I'm doing an experiment on WPF and MVVM, and while coding the ViewModel on Vb.net I noticed this red wavy lines under my ObservableCollection(of T)s T_T
Anyway, the application is in WPF & VB.Net, under the .Net Framework 3.5 (I checked) and I have an 'Imports System.Collections.ObjectModel' on top of my class. Intellisense shows the other classes on System.Collections.ObjectModel except ObservableCollection.
Here's a screenshot.
So, why is ObservableCollection(of T) missing and how do I make it appear?

I am trying to publish to my hard drive so it can later be burned to CD or DVD a project I have developed and I seem to be missing that file. The person I developed it for does not have good internet access, so downloading such things as SQLExpress and DotNetFx35Client is all but out of the question. How and where do I get the file? I know where to put it on my hard drive once I have it.

I have been given the source code to a 2005 VB project to modify. But I can't find the .sln file or a vbproj file or open the project. Don't I need that file to open the solution correclty? or do I have to start a new solution and just add in all files?

I completed my final project for a .NET course two days ago and just noticed today that all my project files for every project I have on my computer (about a dozen or so) are missing all the project files except for what's in the bin folders. The folder structure it seems hasn't been affected.

Could I have been googling with no joy regarding the fact that my program is not displaying changes made when I run it (Debug).
It is an old program (hence the 2003 VB.NET code) I wrote for my daily use and I decided to make some modifications to make it more useful.

Using VB.NET 2008 SP1 on Windows XP Pro SP3:
I am using an existing COM dll that works fine in VB6, on the same development machine. The VB6 app compiles and uses this dll without issue.
I start from scratch to design a new Windows Form application in VB.Net. Then when I try to add a reference to this dll, the reference is added to the references list but the path shows as <The system cannot find the reference specified>. If I select this reference in the list, the properties window shows a blank for both the reference name and the path. At the same time, a reference is added for VBA, and it shows the reference name (Interop.VBA) and path correctly.
I used dependencywalker to find the dependencies for this dll. It has 3: user32.dll, kernel32.dll, and msvbvm60.dll. So presumably I have all necessary dependent files.
I have tried un-registering, re-registering the dll. I have tried the command line switches for devenv.exe to reset settings and to launch in safe mode. I created a new user account to see if it was related.
I have tried picking the dll from the Add References, COM tab and also via the Browse tab to select the file directly. Same result all cases. I also tried putting the dll and msvbvm60.dll in my bin folder.
I don't understand how the reference name and path are missing in the properties window when the reference name is right there in the list and I select the path directly when I added it. There are no other instances of this dll registered.
I tried using tlbimp from the command prompt with verbose switch, I get the error:
System.Runtime.InteropServices.COMException - Error loading library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRAY)). I wish it would tell us what is missing.
It must be registered properly and all dependencies available for it to work in my VB6 app, Re-writing the dll is not currently an option.

I have a listview that I populate with data from a recordset during runtime. After the code has executed and I view the listbox, my columns are missing. I am 100% shure the listview is populated with data. The listview view property is curremtly set on Details. If I however switch the view to anything else eg. view=list, I see the listview items in the listbox. I need to show the user all the columns.

in one of my previous posts, I wondered why it is that my application runs well on my laptop, but not on the laptop on my desk...When I run the application on the laptop on my work, it works...it loads...but the graphic part won't work. He gives a red cross with an OverFlow Exception, which he doesn't give when debugging on my own laptop. I checked for the memory use of the system and it only needs approx 100Mb when it's running the complete graphical part.
I was wondering whether it's possible that my laptop on my work doesn't have the right dll files to do it all. I only use standard dll-files from Visual Basic, so no downloaded dll files.Do you have to add somewhere that he has to include the Drawing.dll? because all the rest works really fine.
