No solution I'm afraid, but I have narrowed down the exact situation under which it occurs which could help to diagnose the cause and find a solution

Problem: It only happens when a UserControl is being hosted and that UserControl has a control(s) that can accept focus.
OK: If you use an empty UserControl or one that only has non focusable controls, it behaves as expected.
OK: If you host a TextBox (or any other edit control) directly, it also behaves as expected.

Thank you very much for your effort!

Anybody else on this issue? It shouldn't be that hard...you'd think. Confused | :confused:

I'd file it as a bug report on Microsoft Connect.

Hmmm, the process of bugreporting seems excruciating, frustrating and the average results too meager.
I'd be more interested in a workaround or fix.

If anyone else thinks this is worthy of reporting to Microsoft, I won't stop you and be thankful for it.

Kind regards to all you nice people.

Have you got anywhere with this?

Microsoft have been able to reproduce it which is a good first step, but doesn't mean they have a fix or workaround for it of course!

They better ought to be able to reproduce it... I've been battling this for quite a while now. Smile | :)

Thank you for reporting this, I must admit Microsofts reponse so far has pleasantly surprised me.
Still no luck in getting around this issue though.

Does anyone else know a solution for putting a complex compound control in a toolbar?

netogg7-Jul-09 9:16

Re: Taborder in toolbar? CanSelect?

7-Jul-09 9:16

I have been trying this with a "compound"control on this same form as the toolbar is.

The compound control is a Panel with a Texbox inside (child control) on the very Form.
In the Form's Constructor i do;

toolStrip1.Items.Insert(2,new ToolStripControlHost(panel1));

With the same results. I think this narrows the bug to:

When using a ToolStripControlHost to host any ContainerControl with any focusable controls in a ToolStrip, tabbing between controls on the ToolStrip does not cycle through all controls.

You might wanna link Microsoft to here. Thanks again.

Continuing from the previous code... In my example i had 4 ToolStripButtons and panel1 inserted at position2 in a Toolbar.

Put a break on the added code in the Constructor and debug. Step once withF11.
In the watch Window add 'toolStrip1'. Follow the tree to:

toolStrip1.Items.base.Non-Public members.System.Windows.Forms.ToolStripItemCollection]. owner.Items.Non-Puclic members.base._innerList

Each of the Items in the List represent the Properties of a Control on the ToolStrip. And each of these (toolStripButtons) have their CanSelect property to true. Except for the inserted Control (ToolStripHostControl) at position 2 == Item[2], the third item in the List, which has CanSelect false.

This might be an explanation for the problem.

Now how does the CanSelect property get there? And how do I set its value? Better yet, how to solve this???

Reading excel file in blocks

Sorry for stating the obvious, but when you install more than one database on a machine, they would have different names, and your connection strings need modified including the name.

Hi,

I would like to know is there any way where we can read excel file in blocks("x" rows at a time) so that the entire file is not loaded into memory.

Replies would be appreciated.

means you want to read for example A1 to A20, something like this

I assume you're talking about loading the data from an excel spreadsheet into a datatable (for example). I wrote the following snippet that will extract the top 10 lines from an excel file using a database connection:

static void Main(string[] args)
        {
            string connStr = @"Provider=Microsoft.Jet.OLEDB.4.0;;Data Source=C:\temp\XlsJetTest.xls;Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";";
            OleDbConnection conn = new OleDbConnection(connStr);
            OleDbCommand comm = new OleDbCommand("select top 10 * from [Sheet1$]", conn);
            conn.Open();

            OleDbDataAdapter da = new OleDbDataAdapter(comm.CommandText, conn);
            DataTable dt = new DataTable();
            da.Fill(dt);

            Console.WriteLine("RowCount:\t{0}", dt.Rows.Count);
            Console.ReadLine();
        }

A little bit of SQL manipulation should allow you to be able to 'page' through chunks of the spreadsheet (you might have to write a couple of functions to do something clever).

It definitely isn't definatley

I think he want's to read the first ten lines without opening up the excel file in memory as a whole (which is done above).

If that is the case, then no, it cannot be done that way.
