The problem is: I have a list of objects, with some containing the same PlanId property value. I want to only grab the first occurrence of those and ignore the next object with that PlanId. The root problem is a View in the database, but it's tied in everywhere and I don't know if changing it will break a ton of stuff nearing a deadline.
So, if I have a list of PlanObjects like such.
Plan1.PlanId = 1
Plan2.PlanId = 1
Plan3.PlanId = 2
Plan4.PlanId = 3
Plan5.PlanId = 4
Plan6.PlanId = 4
I want to take a sub-list from that with LINQ (italics mean an item is not included)
Plan1.PlanId = 1
Plan2.PlanId = 1
Plan3.PlanId = 2
Plan4.PlanId = 3
Plan5.PlanId = 4
Plan6.PlanId = 4
For my needs, it doesn't matter which one is taken first. The Id is used to update a datsbase record.

The situation: when i build my project (or publish) Visual Basic 2010 makes and exe and a couple ddl files. when i run the project with the .exe and the other files the program works perfectly.
My problem: I want to share it with friends and it is just a verry little program ( a n internet radio) so i want it to be 1 .exe with out any other instalation needed so i can easly share it to anyone who wants it. when i make an even smaller program and Debud->build it, it is only 1 exe and no instalation needed. so is there a way to make my program to 1 exe only?

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

I am trying to get a list of files using this line of Dim files() As String = IO.Directory.GetFiles("D:", "*.*", SearchOption.AllDirectories)But it errors out on folders that are inaccessible, like the RecycleBin folder & the program stops. So how do I get a list of files in all folders, while skipping the inaccessible one

I have many applications that create TLB files which I guess are so that vb2005 can comunicate with the DLL files. Now what I would like to do is have all my TLB files in one folder and have my application point to that folder to use them.The problem I am having is that my EXE will not run unless all the TLB files are in the same folder as the EXE. I do not want this. I want to put some code into my file that sais that the tlb files it needs are located in say: [code] and still have it work. again right now they all have to be in the same folder which is really bugging me.

My application creates a file by writing to System.AppDomain.CurrentDomain.BaseDirectory() & "data/" & filename...Now this works fine usually, but I just added a setup utility to the app, so now it installs to the program files directory. It installs correctly and creates the data folder, however when it tries to write the file it gets an exception "unauthorized access".

I am trying to create a log file to log when an exception occurs (if it does) and what exceptions occured. I have posted the code I have so far. What I would like to do is be able to set the path I want it to go to (ie: C:VB ProjectLogs). I can run my code with the current Logging code but cannot find the file. Is there some sort of create command i need to use first?
Sub LogWrite(ByVal ex)
Dim time As String
Dim Path As Microsoft.VisualBasic.Logging.LogFileLocation

I'm doing a small tool that basically wipes the document properties of each .*doc file in a specified folder. The code is working, however, if the document is already opened, I'm presented with a text box asking if I want to open a read only copy etc. I want the code to abort if that happens and rather write it down in a log file or something. And just move on to the next file. How can I do this? I'm talking about editing thousands of documents.
This is the code I have so far:
Imports Office = Microsoft.Office.Core
Imports Word = Microsoft.Office.Interop.Word
Imports System.IO

I have searched other forums, google, etc. and have not find a solution. I am creating a VB.NET application using Visual Studio 2010. My application runs fine inside the IDE. Outside of the IDE, it crashes immediately with an OOM exception. I have compiled the program in both VS 2010 and VS2008. The outcome is always the same. I increased my Desktop heap to 12288 meg from 3072 meg thinking that was the issue, but the outcome is the case. Although the increase does improve my response in the IDE. The error is also being reported as related to mscorlib.dll; and my version is for 2.0 framework is 2.0.50727 and for 4.0 framework is 4.0.30319. I am running Windows XP/SP3.

Is the only way to create custom exceptions to inherit from System.Exception?
I wish to create a class that can be thrown as an exception but i do not wish to inherit from System.Exception because i have a base [Object] class in my library which all my classes should inherit from and i wish my custom exception class could also inherit from it.

I'm my program always fails at the same line:
objUser = GetObject("LDAP://CN=" & strUser & "," & ADPath)
If I reduce the code down to just this:
objUser = GetObject(), I still get this exception:
"Cannot create ActiveX component."
After googling this for about 18 hours, I found that it could be because of a permissions issue. I am a local administrator on the PC, so I believe that takes care of permissions. Secondly, I discovered that the dll file might not be registered. I tried to use the following command to register the dll file I think is being used:
regsvr32 "c:windowssystem32wldap32.dll"
It says the following:
Error - The module "C:windowssystem32wldap32.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:windowssystem32wldap32.dll" is a valid DLL or OCX file and then try again.So no matter what I try to do, I keep getting this unhandled exception error that says that it cannot create the activex component. What do I need to do to be able to use this getObject() command? Is the problem with LDAP? What activeX or DLL file is failing if even just running the getObject command gives an exception?

I have a 'For Each' loop that contains some items I don't want to analyse. Now I use a GoTo command to 'skip' an item. But this is not very elegant and (knowing .NET) there is probably a way to skip to the next item without using GoTo.
I'll show you a simplified version of my loop, designed to add all animals to a list, except the Leopard :

following is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For Each dgvRow As DataGridViewRow In dgvAccesList.SelectedRows
Dim dgvNewRow As New DataGridViewRow
