The following code should work:
Array.Copy(lookupRows,Joe,lookupRows.Length)

I tried that and got an error: Value cannot be null. Parameter name:destinationArray.
Which is kinda silly I think but. . .
I also tried CopyTo which produced the same error.

Joe = Array.CreateInstance(GetType(DataRowView), lookupRows.Length)
Array.Copy(lookupRows,Joe,lookupRows.Length)

OK That worked THANKS !!
What if I need Joe to be an array of string ?? How could I / can I "typecast" this to a string array ??
Thanks again for the help so far !!

Array.Copy won't work, since there isn't a direct cast from DataRowView to String. You'll need to copy the array manually:
Joe = Array.CreateInstance(GetType(String), lookupRows.Length)
Dim i As Integer
For i = 0 To lookupRows.Length - 1
Joe.SetValue(lookupRows(i).ToString(), i)
NextHowever, since DataRowView doesn't override the ToString function, you'll just get an array filled with the string "[System.Data.DataRowView]". The DataRowView class isn't serializable, so you would need to write your own function to convert it to a string.

I am using VB6 and am having a little problem. I am using the ToolTipText property of an MSFlexGrid control, and although the tip is displayed properly, if I click on the flexgrid while the tip is displayed, the tip will disappear and leave a light gray rectangle in its place. It doesn't seem to respond to the refresh method and I am stumped. Any ideas on how to get rid of the residue?
Thanks,
Andrew

Several of my forms contain Adodcs, whose recordsource is a SQL statement containing a variable name. the Adodc (and bound datagrid) work fine for all, but whenever i load or unload the project i always get the following msg:
"ADODC: No Recordsource specified, ADO: cmd text was not set for command object"
Is there anything i can do about this? Thank you in advance!

in my datagrid i have allowed for updates. the datagrid is bound to an adodc, whose datasource is a SQL statement (ie not a table in the access database). the datagrid contains 3 columns - 2 from the products table in the database and 1 from a related price table. how do i reference these 3 fields (for an insert SQL statement) when adding and saving a new record (row) in the datagrid? if you need any additional information, please let me know! any help would be greatly appreciated!

Hi, My name is Rachel. I'm looking for a simple grid, no bound to database.
I need the ability to define simply:
1. The number of columns and rows.
2. The height of rows and width of columns.
3. To control easily on the selected cells.
3.1. I need to the ability to select some cells that are located far from one another.
Thanks Rachel

O.K I found it. It is now as VideoSoft FlexArray and not as FlexGrid.
But now there is a new problem. It is not share componenet thay want me to buy it, almost 300$ for this. I remeber that the flexgrid was free one.
Also to your ask befor. I do not have VS6 on my computers. I used it in previos works I had. On my current computers I installed the VS.NET from the start.
Thanks Very Much

Actually, the flexgrid in VB6 was not free. You could use it but it kept popping up messages asking you to buy it. I guess .net just tightened the rules and made it so that you have to buy it before you can use it..

the columns in my datagrid are Code, Company, Address (based on a table in the database). the datagrid is bound to a SQL statement. is it possible that when i either:
(1)highlight a record, and press a command button and text boxes in another form will be populated relating to each of these columns (ie in the second form, i would have textboxes for Code, Company and Address)
(2)double-click on a record (ie row) and the textboxes will be populated?
i am very unsure of how to reference rows and columns and cells in datagrids so this is why i am asking this question.
Any help would be much appreciated!

I got .NET Enterprise Architect Edition installed in my machine.
Every time I try load a new project the application closes down without giving any error message but that project is somehow saved in the project list. Then when I re-start the .NET and open one of the saved projects and try to add a new windows form, again the application closes down.
I tried repairing the .NET but same thing kept on happening.
I tried re installing .NET but same thing kept happening.
I didn't try reinstalling the OS and then installing .NET.
I installed the service pack 2 for .NEt as LeeDavies Suggested.
Still .Net crashes when I load a windows form.
I'm having a Intel P4 with 256 Ram running Windows 2000 professional edition.
Why is this problem pertaining?

i am trying to populate a datacombo box based on what has been chosen from another using the following code:
Dim RS As ADODB.Recordset
Set RS = New ADODB.Recordset
Dim strProductType As String
strProductType = DataComboType.Text
Dim descSQL As String
descSQL = "SELECT Product.Description FROM ProductType INNER JOIN Product ON ProductType.TypeCode = Product.TypeCode WHERE ProductType.Description= '" & strProductType & "'"
Set RS = Conn.Execute(descSQL)
Do While Not RS.EOF
DataComboProduct.DataField = RS.Fields("Description")
RS.MoveNext
Loop
However, the second combo box does not populate at all - why is this? Thank you!

Hi
I assume that "DataComboProduct" is the name of your second combobox, and that you are sure that you recieve records to your recordset.
I have not used the "DataField" method so I don't know how it works.
My suggestion is:
DataComboProduct.AddItem RS.Fields("Description")
Good luck

Thank you so much for your help - i tried the AddItem method (which does make sense) but it returned the error "Method or data item not found"....is there anything else i could try??!!

I'm not sure but I think the error message says that it couldn't find RS.Fields("Description"). When you write your select statement you use Product.Description, maybe that have something to do with it.
Try this, not so nice, but it works
RS.Fields(0) 'Description
If you had recieved more info you should write
RS.Fields(1) 'Name
RS.Fields(2) 'Street

we want to move to n-tier using .NET.
Our Current Env:-NT/SQLServer/VB6 -ClientServer App
Planend New Env:-NT/Oracle/VB.NET or C#
here is what we are planning :-
vb client->.net components (developed in VB.NET/C#) ->Oracle
if somebody can advice on the following..
1.Should we host the components in COM+ as it gives advantages like object pooling and dbconnection pooling, but at the same time is it really beneficial?
Are the advantages really worth?
Our thin client downloads lot of data upfront and then it becomes very user intensive app.
2.what should be the medium to communicate from client to components?
a.remoting with http/tcp
b.can we try to use webservices.
thanks in advance

Did this easily in VC++, now I'm trying to learn VBasic 6.0...
ClassA
ClassB - includes pointer to an ordered list of ClassA's
ClassC - inherits from ClassB, includes pointer to one ordered list of both
ClassA's and ClassB's
All classes created and destroyed dynamically, multiple instances
On form:
Custom ListBoxA - with pointer to list of ClassA's whose member variable
"name" determines items in ListBox
Custom ListboxB - same as above, but ClassB's
Custom ListBoxC - same, but both ClassA and ClassB as items
the problem:
Drag items from ListBoxes A and B and drop onto ListBox C. Want to create custom dragndrop mousepointers which consist of the text from the listbox being dragged (can I create an icon/cursor on a device context and assign that to the pointer??)
VBasic doesn't seem "pointer-friendly." Can I dynamically create a List of ClassA objects, then point to it from one or more of the listboxes?? I'm still new to VB's data types.
Is this the kind of thing I would use a Collection class for?
One more thing, sorry for being so needy. I want to be able to re-order items within the ListBoxes, by drag n drop, so I need to know exactly where in the listbox the mouse is pointing... ideally which item number as well as which pixel within the item's rectangle. Can I do this in VB 6.0 or is there a better method to this??
Thank you to anyone who has read this far and who responds.
Tym!
