• SQL Server FYI: Using Try's with Finally

  Within my script component I was having some difficulty getting nested Exceptions to bubble out of the script component logic. The symptom appears when you get an ex.message of "Object reference not set to an instance of an object." As soon as I removed the Finally section my message (or the actual Exception object) was properly passed to the caller. I've only done minimal work with Try/Catch/Finally structures. Is this normal Thanks, Jeff Tolman E&M Electric JazzGeek wrote: The problem comes when there is a Finally section after the Catch. The message that I throw up to the caller does not make it and shows up as the "Object reference not set to an instance of an ob ...Show All

• Windows Forms Cannot Read .Text Property of TextBox

  I am simply trying to read the .text property of a TextBox in VS2005 but, even though I know there is text in there, no text is detected. I'm wondering if it has anything to do with the textbox being on a tabContainer in a SplitContainer. The textboxes are bound to data and the data displays on the form. My code recognized that the textBox is there but does not read the text: foreach (TabPage tp in tabControl_ProcA.TabPages) { tabControl_ProcA.SelectedTab = tp; if (tp.Name == "tabPage1_Cabinets" || tp.Name == "tabPage2_CylPipes" || tp.Name == "tabPage3_AngleIrons" || tp.Name == "tabPage4_Beams") { foreach (Control ctl in tp.Controls) { ...Show All

• Windows Forms Detect Computer Restart

  Is there any way to detect whether this is the first time an application is running since the user has logged on to Windows There is a bit of functionality that I would like to reset whenever the computer is rebooted or the user logs out and logs back in and I would appreciate any information on how to detect this Thanks for the tips. Any ways of accomplishing this in a purely programmatic way - not including creating files in the Startup folder (that can very easily be deleted by the user) For example, is there a registry setting somewhere that gives a DateTime stamp for the last log in to Windows If there was, I could record the times in which the app was started and determine if there has been a recent ...Show All

• Visual Studio Express Editions Update Combobox DisplayMember based on DataGridView CellContentClick

  OK, now that I have the database binding I need to accomplish the following: The Form.DataGridView shows the table info. When the user clicks a row, the CellContentClick event kicksoff creating a query that combines the "Last_Name, FirstName" into a new column called FullName. This then updates the DisplayMember value for the combobox to FullName. If someone could show me an example, I would appreciate it.
