Should I write down something like this (see ??? places):
(theGrid.DataMember= "Table1"; // It is so already without programming)
(theTable= theDataSet.Tables[0];)
(theDataSet= (DataSet)(theGrid.DataSource);)
for (i=0; i < val; i++) {
theTable.Columns.Add();
theTable.Columns[i].ColumnMapping= ?????;
}
and below:
for (i=0; i < val; i++) {
acol= new DataGridViewColumn();
acol.CellType= ???;
theGrid.Columns.Add(acol);
}
What do you mean with "define the types"?

Your site reference http://www.rustemsoft.com/DataGridViewColumns.htm is splendid! Thank you very much.
I've found what it’s all about! In my DataGridVies there was designated that
AllowUserToAddRows as False
AllowUserToDeleteRows as False
After setting them to True and using new DataGridViewColumns there occurred blank cells. It is already much better...
When using the old routine I am getting an interruption because of Column Templite (for new column) is not defined. It is much better too.
I'll try investigate further. Thank you.

Answer is found. There is a quite easy way:
theGrid.AutoGenerateColumns= true;
And the grid arises automatically like the old DataGrid.

For a treeview i would like to change the mouse cursor to an hour glass after a delay when selected tree nodes take a long time to populate. I was able to do this in VB6 using a timer event, where a busy flag is set and then the timer event checks flag to determine if cursor should be changed to an hour glass. When i try to do similar in C# the cursor does not change. I am able to change the cursor in the code populating the node, but that causes flickering becasue the hourglass is shown even when selected nodes do not take long to populate.
Am i dealing with some kind of multi thread issue here? What is the normal solution?

when your about to do your complex and time costing code, simply add
this.Cursor = Cursor.Busy;
// your code
this.Cursor = Cursor.Default;

Hi all,
I have to perform logout when the user is idle for certain time. here iam checking the user idle time in the timer. if the time exceeds 1 hour i logged out the my app. and display messagebox "User logged Out" with Ok button.
my problem is after every 1 hour the messagebox displayed over and over(eg. if the user idle for 10 hrs. 10 message box displayed). how to avoid this. is there any way to check whether the user responded to previous messagebox?. if so we have to display the message else we should not the display the message.
Please help

if you are using MessageBox.Show then it is a blocking call and you can do something like this
if(clickedok == true)//make clickedok static or class variable.
{
clickedok = false;
MessageBox.Show("User logged out");
clickedok = true;
}
if it is custom dialog box you can set the flag on onclick event.
Regards

public bool _isNotified = false;
if(!_isNotified)
{
DialogResult msg = MessageBox.Show("User logged out", "Logout Notification", MessageBoxButtons.OK);
_isNotified = (msg == DialogResult.OK);
}

Hello. I want to get some values with C# from an excel file but I got below error message.
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in WindowsApplication1.exe

I referenced Microsoft Excel 11.0 Object Library and I use .Net 2003. What might be the problem? My codes are below. Thanks.

Make sure that you're Main method is marked with the STAThread attribute as all COM Interop requires this.

When using Visual Studio I am very doubtful that this can be done, alas if you use something like NSIS or InstallShield, you can specify a limit to make the file sizes, infact I am very sure that you can specify that this will be going on a 700mb cd-rom, make sure the resulted files do not exceed this size, or span across two or more cd's.
 2gb of resources, hell boy what you packing?
