Compiling the program in Visual Basic Express produces no errors. However, if the program is imported into the Excel Developer environment; I get the following error: Expected: end of statement with the equal sign highlighted.

Declaring & Initializing String Array?
Mar 10, 2011I'm trying to return an array of strings from a function, and got surprised by an error.
I would have expected this to work, but it produces an error:
Public Function TestError() As String()
Return {"foo", "bar"}
End Function
[Code]....
I guess I'm unclear on the meaning of the {}'s - is there a way to implicitly return a string array without explicitly creating & initializing it?
Initializing Performance Counters In Array

View 6 RepliesSyntax To Search (and Return Results) In Two Dimensional Array
Jan 11, 2012The following code works just fine:
Dim wksSheetNames(0 To xlsWB.Worksheets.Count - 1, 0 To 1) As String
Dim i As Integer = 0
For Each Wks In xlsWB.Worksheets
Wks.Activate()
wksSheetNames(i, 0) = xlsApp.ActiveSheet.codename
[Code] .....
What is the best vb.net based search method that would permit me to search for i.e. "Sheet2" and be able to obtain "Cats"? I attempted to ascertain the index number of "Sheet1" with:
Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")
Then obtain the value "Cats"
wksSheetNames(SheetArrIndex, 1)
But I received an error message:
Code Line ->>>> "Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")"
Error msg ->>>> "Only single dimension arrays are supported here.:
Obviously I do not know how to Search and Return the results of a 2D array.

.net - Add A @ In Front Of A SqlParameter Name?
Apr 20, 2012In one of our application the parameters passed to a stored procedure in this way
Dim parm As New SqlParameter("searchText", SqlDbType.VarChar)
parm.Direction = ParameterDirection.Input
parm.Size = 50
parm.Value="test"
cmd.Parameters.Add(parm)
and the procedure contains a parameter as @searchText
ie the parameter name passed from the code is searchText and that in the stored procedure is @searchText .
But it is working properly, i am always getting the required results.
So my question is like so there is no need to specify @ before the parameter? Whether it will append @
Converting VBA Related To Variant And Array Creation/Initialization Syntax To .Net?

Sub SelectColorsViaArray()
Dim e As Variant
Dim r As Range
Dim x As Range

3) With the above, I still do not understand how to integrate the Variant and Array differences from VB6 to VB.Net. I know what to do with all other like: Application.FindFormat.Interior.ColorIndex ... etc.

View 1 RepliesInitializing WPF Application?
Feb 17, 2010I am writing a WPF application in VB 2008, and need to establish a connection to another system to get pertinent information and if not exit gracefully without displaying the form. I thought I would be able to do this in the Application classwithin Application_Startup and set some custom properties. However, it doesn't appear I can expose these properties outside the Application class without re-instantiation it, which is bad thing. Even variables set up as Friend don't appear to work either.

Initializing A SAFEARRAY Ref In C# (port From VB?)?
Nov 21, 2011I am working with a third-party COM component (i.e. do not have its code). The method in question has the following outline:
HRESULT GetTableInfo(
[in] BSTR bstrTableName,
[in,out] SAFEARRAY(BSTR) bstrColumnTitles,
[in,out] SAFEARRAY(long) lColumnPos );
I have tried to pass a ref to a fixed-size array ((Array)string[6]) and to a List.ToArray(), but it keeps crashing on me. E.g.
Array arr1 = (Array) new string[500];
Array arr2 = (Array) new int[500];
table.GetTableInfo(filename, ref arr1, ref arr2);
To be more specific: I already tried any value for the size (the correct one should be 44). Tried the same for the capacity of a List<>, but that didn't help either. I also tried different types, but it does not accept any other than int.
I don't know why it keeps crashing on me with a general error of that COM component (basically indicating that something is wrong, yet not saying what exactly), since I can confirm that the following VB code works:
Dim TitleList() As String
Dim PositionList() As Long
Call objTable.GetTableInfo(txTableFile.Text, TitleList, PositionList)
