How can I speed up the drop down of a combo box inside a datagridview column. when I click on the drop down button to open up the list in the combobox type column of the datagridview, it takes 2-3 seconds to drop down. Can anybody suggest what might be the problem ?
Thanks in Advance.

I have a datagridview control in which i have got a column of type DataGridViewComboBoxColumn. I populate this column's combo when I load the form. But while running if i click on the column's drop down button, so that I can view the list of data in the combobox of the column, it takes 2-3 seconds to show me the list. How can I speed up this drop down of the list so that I can make the application faster.
Thanks in Advance.

If it comes like that, odds are you want to read it as XML. Odd that the XML is not better formed. Looks like you want to use the string.Split method and either split on tab, or if that's lots of spaces, just get the items in the array that are not blank.

1 - the split method on the string class
2 - depends, what sort of table ? The web abounds with examples on how to connect to the various databases that exist.

I have written a Windows Service in VB.NET 2005 for the purpose of logging data from a nursecall system. The data is written to a SQL database. It is important to know when logging has started and stopped and this is done by writing an entry to the database each time one of these events occurs. This is happening now when the service starts automatically on system startup. The 'stop' entry is even written in the event that the service is stopped manual (not something that would normally be done).
However, if the system is closed down, the OnStop sub is not being executed.
It looks like I need to detect a System Shutting Down event from within my code and then execute Me.Stop, forcing the OnStop sub to execute.
Can anyone help in suggesting how to detect that a system has commenced shutting down?

Hi I have developed a project in vb6 and converted it to vb.net 2005 Express edition, fixed the issues after conversion, also did some more development wok.
Now after completion of the when I built a release I am not able to install it on client’s place. Tried running application from the exe n debug folder by coping the entire folder on the clients machine but it effused to work..
What I am suspecting is that there is some dependencies from VB6 installation but I am not able to figure it out
What should I do?

Seems more likely that the .NET framework is not installed on the target machine.

.net framework is installed in the target machine...
The application works fine if i also install VB6 in the target machine.. That made me sure that there is a issue of VB6 references and dlll

<br />

Dim cmbcol As New DataGridViewComboBoxColumn<br />
<br />
With cmbcol<br />
.DataPropertyName = "emp_id"<br />
.HeaderText = "emp_name"<br />
.Width = 80<br />
.DataSource = ds.Tables(0)<br />
.ValueMember = "emp_id"<br />
.DisplayMember = "emp_name"<br />
End With<br />
.Columns.Add(cmbcol)<br />
End With
But there are some problems

2>Second is selection of the item of combobox is not properly worked,i need to use emp_id when user select the name of employee in combobox of datagridview
Any idea would be appreciated heartly
