Error Message Saying That SplitNumbers Cannot Be Of Type String?
Dec 15, 2011
I have to create a calculator. In order to do the calculation, when the math operator is entered, there is a space on either side, so that I can split by the white spaces.
[code]...
This was my original idea of how I could accomplish my goal, however, I get an error message saying that splitNumbers cannot be of type string. Do I have to create an array to do this or is there an easier way than what I'm seeing?

Why am I getting that error message? This is the code which it's happening to:
Public Class frmford
Dim LoanAmount, InitialPrice, Make, TradeIn, OriginationFee, DepositAmount, Model, Options, AirConditioningTax, GST, PST, Total, Subtotal, APR, Months, RoofRack, SunRoof, SideAirBags, TintedGlass, RearSpoiler, GPS, PowerLocks, FreightAndPDI,
[Code]....
I tried to Dim those variables as double and it didn't work either.

I am running a web server using VB.net and I have a bunch of pages that need to utilize similar functionality, so I was thinking of creating a shared base class that incorporates all of this shared functionality. I created a file call it SharedBaseClass.vb, and I also have a class that should inherit from this class, SubClass.aspx.vb. The Top few lines of the the parent class look like this:
Partial Class SharedBaseClass
Inherits System.Web.UI.Page
And of the child class that should inherit:
Partial Class SubClass
Inherits SharedBaseClass
Then at the top of the SubClass.aspx file it looks like this:
<%@ Page Title="" Language="VB" MasterPageFile="~/Main_SA.master" AutoEventWireup="false" Src="SubClass.aspx.vb" Inherits="SubClass" %>
Assume that all of these files are located in the same directory.But when I try to run this, I get an error:Compiler Error Message: BC30002: Type 'SharedBaseClass' is not defined.And then the highlighted error is on the line that reads: Inherits SharedBaseClass I've also tried importing the file to no avail.

I now have SQL Parameters set up and I'm using them to save/delete/add my data. This all works well, except when it's trying to save a combobox to the datatable it appears with the error above.Majority of my comboboxes have datasources, and the valuemembers of these are the actual list items, not the ID's of the list items.I'm not sure why this error could be happening, I'm fairly sure I've connected everything to the binding source correctly; I've checked it a few times.Does anybody know what the cause of this could be? I've looked around a bit and I haven't found much

I am getting the error "Conversion from type 'DataGridViewTextBoxCell' to type 'String' is not valid." When trying to display a cell from DGV in a listbox.I have my variable for the cell reference as follows:
Dim a As Object
a = DataGridView1(4,1)
To insert it in the listbox as follows:
lstLetter.Items.Add(String.Format(a))
I tried:
lstLetter.Items.Add(a)
This will not actually display the entry inside the referenced cell, it shows this in my listbox instead:
DataGridView TextBoxCell { ColumnIndex=4, RowIndex=1 }
how I need to convert this to display.

I've been getting this error when pulling data from a recordset. It is coming from a null entry and as a newbie to VB2008 I'm not sure how to get around this.
here is my code lblShipping.Text = reader("CARRIERCODE")
the error:Conversion from type 'DBNull' to type 'String' is not valid. Basically what i'm attempting to accomplish is to see if there is anything in that field. If so put it into the text box if not leave it blank.

I've got an ASP.NET application that I installed by creating a web setup. I ran into a problem where ASP.NET wasn't registered with IIS so it gave me a "installation was interrupted" message that told me exactly nothing. Anyhow, I finally got it installed, and I can access the main page, but it's telling me that my class isn't defined. The dll is in the same directory as the Default.aspx page Here's the main error information

I created a simple user control and everything went fine.Then I created another of the same control (as a different project) from scratch (creating the controls in a different configuration; but pasting code from the previous one from a text file).As far as I know I did everything the same for creating a user controlCreate a Class Library project Then Project>Add New Item> User Control Then delete the initial class that was added automatically (usually named Class1.vb) Put all of my code and components into the user control class.However, when I wanted to run it in the debugger as I did in the previous project, I now get an error message:"A project with an Output Type of Class Library cannot be started directly."

I have code that loops through a string array to add words one at a time to a line of limited length. I am trying to fit a phrase on up to four lines, centering the words on each line. My code appears to add the first word but on the 2nd word I get a "conversion from string "IS" to type 'Double' is not valid" error.
Here is my code so far:
varResult = Split(strPhrase)
intWordCnt = UBound(varResult) 'count words in phrase
'make words fit on one line
[Code]....
The phrase in strPhrase is "GOD IS LOVE"
I don't understand why I am getting this error when I didn't on the first loop through the code and it Put the word "GOD" into the line.
