In the following code I get the 'localProcessingExeption was unhandled' error

Dim CustID As String = txtSrchCustID.Text
Dim FirstName As String = txtNewCustFName.Text
Dim SecondName As String = txtNewCustSName.Text
If CustID And FirstName And SecondName = "" Then
MsgBox("Please enter a term to search by")
EndIf
This returns "Conversion from string "" to type 'Long' is not valid." I was wondering what the error is and how it's possible to fix it? The other questions that I've looked at were mostly to do with variables assigned incorrect types, but I think that isn't the issue. It occurs when all of the variables are empty.

This never happened to me, and the less data one has (usually) the less you can say what happened.I am trying to write a simple query analyser. I randomly receive these kind of crashes:
[Code]...
The file specified above does not exist. The place where it crashes is wrapped with Try-End Try. Moreover, yes, I have the painting event set up but it should not concern it (or maybe it does?). I have to add that I use visual basic express edition. The error occurs ocasionally - sometimes when I'm lucky nothing happens, and when I'm not then I get this crash.

I am trying to debug my program and I am getting an OleDBException Was Unhandled. It then goes to the path where the error is located. The executable is listed in the bin file and I have re-built and built the application several times. The application is supposed to extract data from an external MS Access database. Note my code:
Public Class frmSpanishFoodStoreInventory
Private Sub StoreInventoryBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StoreInventoryBindingNavigatorSaveItem.Click

I have written an MDI text Editor and I have written a "save" sub routine, please see below
'This sub routine updates the current document or calls the save as routine
Private Sub SaveToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripButton.Click, SaveToolStripMenuItem.Click
[code]....
I am testing this sub routine today and it throws up an error during runtime when a new document is created and the user (me in this case) writes a few lines of text, I click the save toolstrip button and because its a new document, the save as sub routine is supposed to be be invoked, however the application stops running and I get this error message "ArgumentNullException was Unhandled" from Visual Basic.

All of a sudden, when I built my project, it wouldn't read any changes, then all of a sudden, this error started popping up!The description of the error is:An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.and it pops up when the following code is executed:
frmMain.Show()
on the line prior to it I have the code
frmStats.Show()
and that pops up no problem.These errors happened suddenly, and all I was changing in the code (which was in frmMain) were just a few changes to labels (activated by an event).

I get the following expeption when trying to switch from one form to another (click event):
InvalidOperationException was unhandled
An error occurred creating the form. See Exception.InnerException for details. The error is: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "WindowsApplication1.CarDimensions.resources" was correctly embedded or linked into assembly "Driver Seat Configuration" at compile time, or that all the satellite assemblies required are loadable and fully signed.
How can i embed one form correctly into the another?

I have run my program a thousand times throughout its creation and have never had a problem. I entered some code for a NumericUpDown control, and now I get this error whenever a variable is assigned a value. The code for the NumericUpDown control doesn't contain anything, really. No new variables, nothing. If I take the code out, the program works just like it did a thousand times before. What gives?

I'm getting a "TypeLoadException was unhandled" error. The description says Could not load type 'dnUtilities.OtherFunctions' from assembly 'dnUtilities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
So i've got a class library project. I've built that into a dll and am referencing it in a project in another solution. The name is "dnUtilities" and i've stored a lot of subs and functions inside it. I just got this error when i added a new module and tried calling a sub from it. I've got no idea why this error is happening since all the other functions from the other modules work. Besides modules i've also got a usercontrol in the dll. The framework of the dll and my calling project are both 3.5.

I was testing out an application that I created which then I recieved an error as said in this topic title. The application that I am making is one where it requires 2 form GUIs, my main one is called frmConferenceRegistrationSystem (the first picture) and my secondary one is called frmConferenceOptions (The second picture) and what they are supposed to do overall is total up the cost of registering for a conference that is selected in frmConferenceOptions and the error that I am recieving is within the ElseIf statements in the frmConferenceOptions form (third picture and first section of code) And also here is the rest of my code for both of my form GUIs at the bottom of this topic
