Re: DataReader memory size??? half-life10-Jul-08 22:35 half-life 10-Jul-08 22:35  here is an example of Odbc Data reader u read each row at a time until the value of Reaq() is false - no more rows to read u can not read all rows at once OdbcDataReader Reader; while (Reader.Read()) { object[] dataArray = { }; Reader.GetValues(dataArray); } u can use : dataSet to hold data and use datadaptor to fill the dataset this method is more handy where u assign an SQL stat. to the adaptor and by using the Fill method u read all rows to the datatable inside the data set Have Fun Never forget it Re: DataReader memory size???

So if you are reading 1 crore rows, connection has to be open for until it finishes. All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia How to use google | Ask smart questions Exception of type 'System.OutOfMemoryException' was thrown" Raheem MA10-Jul-08 19:45 Raheem MA 10-Jul-08 19:45  Hi All, I'm using SQLBulkCopy class in .net 2.0 I'm passing SQLDataReader object to SQLBulkCopy's WriteToServer () method.

This Datatable is assigned as a DataSource to a DataGridView. This table gets displayed on the datagridview. After that, i am adding a combobox column to DataGridView and filling the cells under that combobox with item selected. I want to retreive the whole updated DataGridView along with the new column and values in the cell into a Datable object. I am able to assign datagridview columns to a newly created datatable object and unable to do same for the datagridview rows. Thanks in advance.

Control Focus for MouseMove Events greytone810-Jul-08 11:13 greytone8 10-Jul-08 11:13  Hi, I am implementing a drag/drop system and am having trouble programmatically firing an event such that the control that receives the event remains focused. For example, if you actually click on a button, and don't release the mouse button all MouseMove events are sent to that button even if you drag your cursor off the control. If you drag off to the left, the button continues to receive mouse events and the X is now negative. This is the desired behavior. Currently I am firing the MouseDown event on a target control by having a member function that calls OnMouseDown() but this does not lock the focus as described above. Can someone tell me how to lock the focus programmatically so all mouse events continue to be sent to the targeted control.
