Please check your code clearly and make sure databinding takes place in one place , which need to be after Initialization(). If you can show me, that cose block, then that will be very nice to trace the issue.;)

Thanks for the feedback. As usual, providing details will help the analysis.
Yes, I have placed all the databinding after Initialization(). The 'load-filtered-data' button has only one statement: a call to a dataview filter routine. In this routine I build a filter statement, using the selected list item:
private void Filter(string comboString)
{
string filterString;
filterString = "EngrName='" + comboString + "'";
DataView myDataView = new DataView(workordersDataset1.Tables["WorkOrders"]);
myDataView.RowFilter = filterString;
this.dataGrid1.DataSource = myDataView;
this.dataGrid1.Refresh();
}
If I remove the call to this function and re-compile, my datagrid loads with all records -- exactly what I want. If I leave in the function call, the datagrid is blank, and the button_click &/or the filter function do not fire. I haven't built any error handling yet, and I'm sure that would help me to troubleshoot.
Thanks very much.

To add, delete, or update, try
http://www.codeproject.com\useritems\ado.asp[^]
You should learn about SQL, if you haven't.
To search for person, you can use the query:
Select * from member where domain=dotnet and exp>1
Good luck.

Hi,
I have created an Arraylist object from an Arraylist class.
I added rows to the arraylist object and I need to find a particular record in my arraylist. How do I do this? Also if I was in the middle of building the arraylist and wanted to call the last record added to arraylist object how can I do this?
Thanks,
JJ

You can get the index of the object using thhis syntax:
ArrayList a = new ArrayList();<br />
a.Add("a");<br />
a.Add("b");<br />
int objectArrayIndex = a.IndexOf("a");
If you just want to access the object with the highest index:
string myString = (string)a[a.Count - 1];
Remember, it's a 0 based array, so subtract 1 from the Count property

In your Visual Studio.NET Solution Explorer, right click your solution and choose the Add option and select New Project. Now select the Setup and Deployment Projects folder icon. Pick the project that targets your code (i.e. win forms or web).
There are plenty of good tutorials if you search on Google.com

Hi. I'm using the "File.Move" method in the System.IO namespace. When I start my program and call this method it executes no problem. The second time I call it I am getting and error message saying "Exception: The process cannot access the file ... because it is being used by another process".
When I close the program and run it again the method runs fine, again for the first time.
I would think the connection is just not closing for some reason. Does anyone know how I can fix this?
|
|
|
|
|
Well, you could try calling dispose() on your object to see if it would help. My guess is your problem is somewhere else. Are you using any FileStreams ? You definately need to close those by explicitly calling Close() on them. Post some more code if you can...

Not enough information. Move what file? Is your application writing it? Are you holding it open? Where does this file come from that your trying to move?
The problem is obvious - "being used by another process". This means that you can't move a file that is open for reading and/or writing. So what has the file open?

My data adapter wizard will not configure a table with more than 100 columns. Is there a way to get it to do so? I have tried to manually configure bt I get a syntax error message when I exceed 100 columns. Thanks
Mark

Do you have the ability to cut down on the number of columns in your table? 100 columns in a single table isn't a good idea.
|
|
|
|
|
I could spit the table into smaller related tables but i will still need to update 118 columns at the same time. It appears that 100 is the limit for a data adapter.
|
|
|
|
|
Split the table into smaller tables and use a DataSet with multiple tables. You won't have any issues with that approach.

I would like to change text on buttons on MessageBox, for example, OK changed to Accept...
I want some unicode text in my application, so I need change these text, help me 
|
|

The possible text on a messagebox is set via an enum. If that doesn't suit, you need to write your own.
