Databinding with Excel

Hi !!

I try to collect information from my Excel file into a datagrid but nothing
happens with this code :

=============== =============== =============== =============== ====
strConn = @"Provider=Micr osoft.Jet.OLEDB .4.0;Data Source=C:\Progr am
Files\concentra tor\example\Cou nterDDE.xls;Ext ended Properties=Exce l 8.0;";

OleDbConnection oConn = new OleDbConnection ();
oConn.Connectio nString = strConn;
oConn.Open();

OleDbDataAdapte r da = new OleDbDataAdapte r("SELECT * FROM counter_range",
oConn);
DataSet ds = new DataSet();
da.Fill(ds);
dataGrid1.DataS ource = ds.Tables[0].DefaultView;

oConn.Close();
=============== =============== =============== =============== ===

what's wrong ? did I forget something ?
What I could not understand is why I can't do a databind() in winforms...
i'm pretty sure that the problem comes from : dataGrid1.DataS ource =
ds.Tables[0].DefaultView;

thanks,

Julien

Julien,

Are you sure that you are getting data from the dataset after the call
to Fill on the data adapter? If you save the XML of the data set after the
call to Fill, is there anything in it?

Hope this helps.

It could be a problem with the version of ADO you are using.

I'm writing what should be a very simple app against an Oracle database. The app has a number of user controls, any one of which is loaded into a main display page using the loadControl method, depending on which menu item a user selects. Each of these controls follows the same basic pattern: Get a dataset from the database and then display the results using basic databinding. Everything works fine except that I'll occaisionally get an...

When I first built a few web pages in ASP .Net 2.0, I thought it was great.

Now I am working on my first real web application on 2.0, and I find this automatic functionality doesn't do much beyond allowing me to generate...

I have tried using Databinding for my application but always seem to find it very restrictive (maybe I don't completely understand it enough). I always seem to find it much easier to display a form, have the user fill it out then put the data into a class representing a data row and then use the OLEadaptor or OLECommands to update the database. My question is has anyone really used databinding in anything but the simpliest application...

How can we control that fill? In a...

Hello to all, I want to know if DataBinding in asp.net 2,0 is better than to fill up the values of the controls of the following form: this.miControlTextBox.Text = valorParaControlTextbox; Performance with databinding is good in asp.net 2.0 ? Would you prefer: databinding or set value to Text property of control ?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
