I hope everybody will help me. I'm doing project in VB.net 2005 in windows form. I designed forms created database and table in SQLServer Now I don't know how to connect this to window form. How to write connection string, non-execute query. Like VB6.0 whatever type in text box, listbox it should be inserted/updated in table column field respectively. Plzzzzzzz help me. Thanks in advance Ashwini Re: Connecting to ADO.NET Ajay.k_Singh28-Sep-07 2:24 Ajay.k_Singh 28-Sep-07 2:24  For using database connectivity on .Net platform, Ado.Net is used. In simple words you will need to use DataSet, DataAdapter and DataConnction objects. However I would recommend you to Google the ‘Ado.net’ and get a complete overview before using this, because concept of Ado.Net is different from Adodc which was used with Visual Basic 6. -Dave.

So you have messed around with you Settings. right click on your Datagrid and select properties. make sure that the "Allow Sorting" is Selected as true.

Now what I know is that an .eml file can have images,attachments and all the e-mail formatting in it. So if I use a simple pop3 client to download message it will download the text part of the e-mail not full formatting - that's what I'm searching for! I found this link : http://www.example-code.com/delphi/download-pop3-email-to-eml.asp but the library is not free or open source , can you find something like this , my dear friends ? I also found another thing :http://www.developerfusion.co.uk/show/2453/ But It uses the winsock control which I can't found in VB.NET. Any one please help.. Thanks, Dan Re: Receive POP3 e-mails as .eml file Dave Kreskowiak28-Sep-07 5:57 Dave Kreskowiak 28-Sep-07 5:57  The file format has absolutely nothing to with a POP3 client. There is no file format specification for saving messages. The .eml format is specified by Microsoft and Outlook, not the POP3 protocol. It's also known as the message/rfc822 MIME type. You can find out everything about the format here[^], or just Google for "message/rfc822 format".

Thanks for help. But Is there any way that I can use the winsock example that I showed you in the first post ? I tried but on every line I'm getting an error ! If you have any idea ... ?? :-> Thanks, dan Re: Receive POP3 e-mails as .eml file Dave Kreskowiak28-Sep-07 7:11 Dave Kreskowiak 28-Sep-07 7:11  The code you found was written for VB6, not VB.NET. It's possible to convert it. You'd have to add a Reference to the old Winsock control, I think it's in the list under the COM tab, Microsoft Winsock Control. Dan`M wrote: I tried but on every line I'm getting an error ! I'd scrap the code and rewrite it using .NET Framework classes, but describing how those work is way beyond what you can fit in a couple of forum posts. You're getting most of these error messages because you don't have a reference to the old Winsock control.

Very big mistake. I already told you how to do it, and that didn't involve downloading a .DLL. The one you downloaded is also the wrong file! Dan`M wrote: Can you convert & post the code for VB.NET please ? I can't because my time is short. I do this for about 5 minutes, whenever I get a chance.

Thanks regards Yasin Re: How to deflect a line Christian Graus28-Sep-07 1:43 Christian Graus 28-Sep-07 1:43  You should handle all drawing in a paint event handler. You just can't do it wth controls, not nicely. The deflection is basic physics. Which bit are you stuck on, drawng the line, or working out where it goes ?

Luc Pattyn [Forum Guidelines] [My Articles] this weeks tips: - make Visual display line numbers: Tools/Options/TextEditor/... - show exceptions with ToString() to see all information - before you ask a question here, search CodeProject, then Google Re: How to deflect a line Dave Kreskowiak28-Sep-07 5:51 Dave Kreskowiak 28-Sep-07 5:51  Forget the controls and rendering code for now. You haven't figured out how to represent your game's data properly yet. The graphics you see in any game is a visual representation of the game's internal database. You can't possibly draw anything until you've got your data representation and management worked out.

I am writing an windows service to retrieve files from a network drive mapped as Y: I get the following error... Could not find a part of the path "Y:\verify". When I run an Application it works fine, so I tried to shell the exe from my service, but still get the error! I have read and tried several things but to no success Can anyone please assist me? Re: Windows Service GuyThiebaut28-Sep-07 0:32 GuyThiebaut 28-Sep-07 0:32  Have you tried the UNC e.g. instead of : "Y:\somefile.txt" Try (depending on the path): "\\FredsComputer\C$\somefile.txt" You always pass failure on the way to success. Re: Windows Service André Stroebel28-Sep-07 0:51 André Stroebel 28-Sep-07 0:51  Yes I have tried that, but the share needs authentication. So I get access denied error Re: Windows Service GuyThiebaut28-Sep-07 0:55 GuyThiebaut 28-Sep-07 0:55  Sounds like a permissions/user issue. I am not a networks expert and I guess someone else on this forum may be able to help. Good luck... You always pass failure on the way to success. Re: Windows Service Dave Kreskowiak28-Sep-07 1:54 Dave Kreskowiak 28-Sep-07 1:54  A Windows Service runs, by default, as the Local System account, which has no rights to any network resources. The service does NOT run under the user context. It runs as if a seperate user logged into the machine (actually it DOES login to Windows) with no network permissions. To the service, there is no Y: drive. The only drives that exist are the local floppy, hard drive, and any CD/DVD drives. If you want the server to have access to the network, you have to change the account it's running under to one that has network permissions. Click Start/Run and type services.msc. Find your service in the list and double-click it. In the dialog that shows up, click the LogOn tab to change the account.
