• Windows Forms Validation within a data grid

  I am using datagrids for data modifications. I would like to validate from by cell instead of on a form save. In other words, when someone changes a value in a cell, I want to execute a validation routine to verify that cell. I have looked at the Validating event on the Datagrid but it does not seem to fire. I am using VS 2003 C#. Thanks I usually handle the textbox in a datagridtextbox columns validate event using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Data.SqlClient; namespace DGValidate { public partial class Form1 : Form { public Form1() { ...Show All

• Smart Device Development WinCE UI in Windows Mobile device

  The UI of winCE application does not look the same on PocketPC with Windows mobile 2003 OS. Do I need to have different design for the UI. Generally yes if you support both.

• Internet Explorer Development Still another report on this...

  Having an intermittent problem printing To: From: CC: Subject: Attachments: headers on emails. Usually happens with larger emails or emails with large attachments or emails that have been replied to or forwarded from other people. Have installed Generic/text printer and sent the email to this printer but sometimes the headers are still missing even printing this way. I have if I open the offending email and highlight just one or two words in the text of the email eg Dear John and then print the email using my HP printer (not as text on Generic printer) - the headers then print and so does the selected words. Don't suggest using Outlook as often we only print the first page of emails as we already have the rest of the email on file especial ...Show All

• Windows Forms How to check Windows Form is completely shown on the screen

  Actually the reason for this is: i want to do printscreens within my application(like after i press a button on my form, this button press will run a method with printscreen function), therefore at first i had Application.DoEvents(); System.Threading.Thread.Sleep(1000); but i read up on application.doevents() and there is an issue that it may go into an event twice.. Is there a way to check when the windows form is completely loaded or repainted as i run my application Or is there suggestions to let the application wait while continuing to load cos if using thread.sleep only, the whole application will pause and the form loading will also pause. Or is there any alternative to application.doevents() Let me clarify that i am not using this ...Show All

• SQL Server Ideas for Next Version ...

  To Whom It Concerns - MS Product Design - SQL Server Reporting Services: I've been working with an ASP.NET web based project utilizing SQL Server Reporting Services for a while and have some things that I think need to be addressed in the next version: 1) I finally got security working utilizing the form based authentication of my Web based app and passing that to SSRS through the ReportViewer control. Not that it was easy. From what I see, a lot of people are having problems with this and so I didn't feel like I was alone. That said, instructions on how to do it need to be easier. Ultimately, it would be better if on the ReportViewer control, you could add properties as follows: * Impersonate SSRS User * Impersonization Pas ...Show All

• Visual Studio Express Editions Beginer Help

  Hey, I just downloaded VB Express a couple weeks ago. I'm having trouble finding resources for beginers. I've found all of the video series on microsoft.com but I want a bit more resources. Where can I find them www.google.com www.amazon.com Seriously, if you'r ehaving trouble with the resources you've found, you probably need to buy a good VB *language* book ( NOT one that teaches you how to create forms and use the designer ) and work through it. I bought 'teach yourself C++ in 24 hours' 8 7 odd years ago, and worked through it, I got my first dev job 6 months later ( obviously by going on to more advanced books and learning more than that book taught me ). There's no harm in starting with a s ...Show All

  I have been using the windowsidentity.getcurrent() to reterve a username.

• SharePoint Products and Technologies Configuration Wizard failed - hosts file missing

  Hi, I just want to let you know, that during the Configuration Wizard of MOSS EE 2007 (English) the configuration failed because of a missing C:\Windows\System32\Drivers \etc\hosts file!
