Convert Combo Box String To Integer?

Mar 4, 2012

I'm trying to get a combobox that has a string value in it to be an integer value. So that I can do math with the value that comes from choosing its indexes.The two strings are "one dozen" and "two dozen" of which I am trying to let VB know that they are actually 12 and 24 respectively so I do the math. How do I declare the variable(s) that becomes the selection of this combobox so visual basic does it right without and error?

This is the code I have so far, with "bagelquantity" and "bagelquantitystring" as the proposed method to work with this problem. I'm thinking I set a variable for the strings of the combo box (bagelquantitystring) to be converted from string to integer into this variable, and then a normal variable (bagelquantity) for the rest of the combobox values.

Private bagelquantitycount As Integer
Private totalsales As Double 'accumulator for total sales LIKE totalsales += totalsales
Private Sub MenuFileCalc_Click(sender As System.Object, e As System.EventArgs) Handles MenuFileCalc.Click[code].....

'AddressOf' Expression Cannot Be Converted To 'integer' Because Integer Is Not A Delegate Type

May 13, 2009

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.

After the conversion, the code look like this:

Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer

[Code]...

Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?

Aug 11, 2011

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:

Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)

[Code]...

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

Here is my exact code. There error is Input string was not in correct format:

GraphDate4 = String.Empty
DeliveryProducts = "{ name: 'DeliveryProducts', data: ["

Convert Integer(*) To Integer()

Jan 27, 2010

i tried this, but had invalidcast at line 2.

vb.net
Dim a As Array = Array.CreateInstance(GetType(Integer), New Integer() {1}, New Integer() {1}) Dim b As Integer() = CType(a, Integer())

what i'm trying to do is to create an Integer array with LBound greater than 0. any way would be accepted, or can i say this: my function that takes i As Integer() as its argument does not have to check the LBound of i because there is no way LBound of i will ever be greater than 0
