Form Causesvalidation property Zapss13-Oct-04 3:10 Zapss 13-Oct-04 3:10  Hello, Iam new to c# My Problem is something like this. Create a sample windows application, having 2 textboxes & a command button Set the forms controlbox property to True Write validation event for the 2 textboxes private void txtpassword_Validating(object sender,System.ComponentModel.CancelEventArgs e) if (txtempno.Text=="" | txtpassword.Text=="") { MessageBox.Show("Please Enter User Id and password","Invalid Data",MessageBoxButtons.OKCancel); e.Cancel = true; } while running the application when the user clicks the button1 the focus is still in 1 of the textboxes, the validation event of the textboxes still fire. Same is the case when the user clicks the X button on the control box. i.e validation event is fired and form is not closed Form Causesvalidation property aslo set flase. if i write the code in the Form1_closing event then also the problem is not being solved. This is because the validation event of the textboxes is fired first so the execution never reaches the Form1_closing event. i need to provide this funcationality in my application,How can i do this?

But whenever i shift the project to some other machine, Forms containing those texboxes either doesn't open showing 'Designer error' or if they openn they dosnt display those controls at design time. (if i run the application it works fine but at design times it misbehaves) Any Solution? Thanx in Advance sorry for my bad English.

I need to get up to speed fairly quickly, so I make recommendations on where we go and how, so I'm after some material (a book probably) that will lead me along this route. Can anybody recommend a good book, or even a set of tutorials aimed at my situation? Thanks, Mike. Re: C++ and MFC -> .net and C# advice J4amieC13-Oct-04 0:52 J4amieC 13-Oct-04 0:52  Troelsen's "C# and the .NET Platform" is my bible - heartily recommend it.

If you are in a hurry, but still want to make a firm grounding in C# and .NET just buy these three books and start reading... The last one is more suited as a reference than as a start to end read...

And What is the popular usage of windows registry before save the application setting of user? Re: Use of GAC and registry Vasudevan Deepak Kumar13-Oct-04 0:01 Vasudevan Deepak Kumar 13-Oct-04 0:01  GAC is a .NET special folder version under your windows folder (called assembly) so that all applications that are run in that version of framework can use the DLLs if the DLLs are available registered in GAC.

PrintDocument printDocument = new PrintDocument(); foreach ( string strPrinter in PrinterSettings.InstalledPrinters ) DropDownList1.Items.Add ( strPrinter ); but I got the result "Auto HP LaserJet 6L on XP" "Auto HP LaserJet 1100 on MS" XP is network computer, MS is server so how can I know if they are in network printer not local printer? Thanks About time stamp wk_vigorous12-Oct-04 22:51 wk_vigorous 12-Oct-04 22:51  I try to get the time when the source code is compiled. The code is : string filename = System.Reflection.Assembly.GetExecutingAssembly().FullName; System.IO.FileInfo fil = new System.IO.FileInfo(filename); string thetime = fil.CreationTime.ToString(); But "thetime" is "12/31/1600 4:00:00 PM". What's wrong with it? My mathine time is 13/10/2004. Thanks vigorous Re: About time stamp Anonymous12-Oct-04 23:31 Anonymous 12-Oct-04 23:31  Try string filename = System.Reflection.Assembly.GetExecutingAssembly().Location; System.IO.FileInfo fil = new System.IO.FileInfo(filename); textBox1.Text = fil.CreationTime.ToString(); instead. You are referring to the FullName, which is something like "WindowsApplication 2; Version blabla; etc. blabla" and not a path. You NEED a path, though, or strange things will happen Cheers Sid DataGrid not showing Date & Time StrayGrey12-Oct-04 21:36 StrayGrey 12-Oct-04 21:36  I have been given a C# program to maintain and one of the alterations required is to alter the DataGrid display from showing Date only to show Date & Time. This data originates in an MS SQL database and when I look in debug both the Date and Time are retrieved correctly they just don't display correctly.

What do they actually display? What do you expect them to display? Do you want to know more?
