So if I understood you correctly you have an Excel instance open (standalone) with a.xls open.
You open your program and open say b.xls inside the browser and cannot while your program is open access or set the focus to the instance of excel which has a.xls open until you close your program?
I can't think of anything at the moment which would cause this, would it be possible to have a copy of the program or some sample code which exhibits the same problem? (I'm running Win2K & Office 2003 for your information)

If you:
1. Start a new c# windows app project.
2. drag a webbrowser onto the form.
3. drag a openfiledialog onto it.
4. at the end of the constructor, put:
openFileDialog1.Filter = "Excel Files (*.xls)|*.xls";
if (DialogResult.OK == openFileDialog1.ShowDialog())
{
axWebBrowser1.Navigate(openFileDialog1.FileName);
}
5. open excel and start a workbook.
6. run your app and open a workbook.
7. try to activate (5).
Cheers.

Interesting behaviour, I see if I can find some time to look into it, but I've got deadlines to meet with coursework and exams coming up soon so it's a bit hit or miss.
Sorry, but at least you're not the only one. Does this happen with word docs as well?

No. Word was ok - although when playing around with Word I found some equally dubious problems but can't remember what exactly they were... Thanks for taking the time out.

Has anyone had any luck solving this problem?
I'm currently experiencing a similar problem, only I am displaying 2 excel files in 2 child WebBrowser controls. After the second WebBrowser navigates to its respective excel file (with the first WebBrowser already displaying its excel file) and then setting the focus back to the first window the strange things happen when you try to manipulate cell data or worksheets. (When editing a cell, the text is not displayed in the cell but is displayed on the formula bar on the second WebBrowser. When switching worksheets via the tabs, the sheet disappears from the first WebBrowser and shows up in the second WebBrowser.) It's like the last WebBrowser that opens an Excel file monopolizes the focus of the Excel App instance.
As a test, I tried opening the files in 2 separate Internet Explorer windows to see if the behavior could be reproduced. It isn't. The two excel files can be worked with without any problems.

It might be something to do with the fact that the WebBrowser control's a wrapper around the OCX version but I know that I've got a PITA problem where the browser grabs focus even though it's hidden, disabled, told to handle nothing and it's wrapped around inside a Component that's on the form.
It'd be nice if someone wrote a fully managed browser...
As of how to accomplish that have you ever tried Google?

I want in my RichTextBox this action to do: Backspace key takes the same action like left arrow key. Speaking generally I don`t want to delete characters by backspace key inside the textBox field unless it is the last character.
This code works in TextBox (do the action which I want) but unfortunatelly doesn`t work in RichTextBox.
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)<br />
{<br />
<br />
char c = e.KeyChar;<br />
int start = textBox1.SelectionStart;<br />
int lenght = textBox1.Text.Length;<br />
<br />
if(c == (short)Keys.Back && start!=lenght)<br />
{<br />
e.Handled = true;<br />
SendKeys.Send("{LEFT}");<br />
return;<br />
}<br />
}
Can anyone help me?

Describe "how it is not working".
Do you get a error or what?
And aI think making this kind of behaviour is bad. There are standards and I hope you have a really god reason for doing this...
Q:What does the derived class in C# tell to it's parent?
A:All your base are belong to us!

You asked me why it doesn`t work. It takes two action in the same time. First it deletes charakters (so backspace key works like should work), second it moves cursor to left like I want.
In textBox works only second action which exactly I want. In richTextBox work both of them.
e.Handled = true; code should make a backspace key action not allowed.
Why is that?
I need this action in my richTextBox to validate text which I enter to this.

Errors and Excel, I recently have resolved a major pain when using OLE DB. If you are using the Excel Object Model then ignore this. Basically I was glad to finally discover some info buried on MSDN that helped me resovle reading (importing) data from Excel via OLE DB.
Two things:
In your Connection String Extended Options there is a setting called IMEX. It can have one of the following values:
<br />
0 = Export<br />
1 = Import<br />
2 = Update<br />
Thus, let's say you want to read an Excel file that has a few questionable cells (i.e. IMEX=1). Well without some further intervenion in the Registry, OLE DB still may not fetch the records properly because it uses the first 8 cells in the column to guess the data type. Easy to fix but you have to know about this to make it work.
Nip into REGEDIT and goto to:
<br />
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel<br />
Then you have to tweak the value of a setting called no less than TypeGuessRows. You can choose a value that makes sense in your context, say it might take 100 cells to determine the type in your estimation. Then here it's definitely OK to try 100 as the value. This is an execise in tuning verus trial and error. If you have a humongous spreadsheet, you can use 0 which causes the Type Guess to scan up to 16,000 rows. That's a tad excessive for most apps, so like I said trial and error.
BUT Wait there's more.... when you finally go to deploy your application MAKE SURE your MSI updates the Registry!

Is it possible to install the downloaded application in a quite mode. Using command line arguement "/q" we can install the application in a quite mode when we are installing the msi r exe file from the command prompt or from any other .Net application using the Process.Start with the arguement "/Q". Is it possible to do in the same way in the ClickOnce deployment.
Is it possible to get the values an do some processing like, checking the Licencse key and getting the email id or pin from the user or client.
Please reply me.

Not unless the installer has a quiet option, if it does check the docs for how to invoke it.
An alternative (although a bit more work) would be to use NSIS which does support quiet installs.
Sorry I'm not of more help

We can access delegate invokationList by mthod GetInvocationList (), But we can't use it in a event.
I want to Add a Eventhandler to handle event Control.LoadComplete, but when a server side event occurs such as Button_Click, the click event handler will be invoked before my handler, how can i do my job before it??
thanks for any helps.

Hello,
maybe someone here can help me. I need something like a tooltip. In this tooltip should be displayed a string. Til now it is not complicated. But the problem is that the string should be bind to an object and so automatically updated. Is this possible? is there something available on the whole web?

Have you looked into the ToolTip class?
MSDN
No hurries, no worries.

In this class I have not found any possibility to bind the shown text to a property of an object...
Maybe there is a possibility but I don't find any...
Regards
Hansjörg
