• ACCOUNTINGONLINE.US Simplest method to add e-mail to an application

  I am trying to find the simplest (& hopefully, most flexible) way to add e-mail capabilities to a Windows Forms application. I know I can use System.Net.Mail to send e-mail, but this requires some pretty specific information (server name, username, & password) that my application will not have access to. In an old VB6 application, I used MAPI to send e-mails, which I suppose is still an option in .NET. The benefit of using this is that MAPI handled all of the account information for me - it just "used" Outlook to send the e-mails. The only [minor] downside here was that my application required Outlook or OE to be installed on the computer - which is not really a problem where this application is distributed. Is t ...Show All

• yanivpinhas convert string to date : error out of index range

  In my fresh installation of Visual Studio Professional 2005 Visual Basic I have typed this code dim olddate as date olddate=datevalue("01-01-2006") I receive an error: index out of range exception On an other pc with the same fresh installation this do not happen. Why I have tried with other funtions : ctype, cdate but I receive the same error, while on an other pc this code is fine. Can help you me. Thanks. Spotty has almost certainly nailed the cause - my suggestion is to avoid string to date conversions, and just use Date literals instead: olddate = #1/1/2006# - just be careful that these are always in the month/day/year format. Alternatively, you can also use the globalization class to create a cultu ...Show All

• h1 Error codes

  When I use an add command to add data to an Access dB, supposing that db doesn't exist or a connection is lost to the dB or anything atall, and my VB program returns an error to my program, rather than allowing it to crash is there an error code that gets returned that I can use to handle the program execution appropriately thanks tattoo I have been using the Try Catch block but I guess my problem was how to handle the error. Your explanation of reading the documentation makes sense. One of my problems is If I use the following to do an Update DataAdatper.Update(Dataset, "Table_Name") I'm not sure which is the Class in that statement...

• Alexnaldo Santos How to link buttons and textboxes, to do the same thing?

  I have some tab's, and need to link some buttons and textboxes at different tab's. Is there a way to do it, other then doing it by code What do you mean by "link" DO you want something in common to happen when you click a button or go into a textbox Yes you can do those things but it must be done in code DMan1, for the buttons, a simple Handle to both will work. To the text box, I want them to to have the same thing written on both, and I think I will try it by using a .lostfocus, to copy the string to the next textbox.

• PaoloZ From .Net 2003 to VS2005

  Our project has got some user controls in the old VB6 Version, in the form of .ocx. When upgrade to VB.net 2003, they were changed to interop&Axinterop dlls. Now I hope to open the project in VS2005, and i've done upgrade following the upgrade guidance. But after upgrading, there were some warnings said the reference to those dlls can not be found. I checked the vbproj file of VS2003 and found out that in <reference> node, there're "name" and "assemblyname" properties. When they're the same, the reference in VS2005 is no problem. Otherwise, the refernce cannot be found. I'm really confused about this, anyone can help me Thank you very much. Hi - I'd only expect that ...Show All

• Captain007 Detecting the datatype of a data column

  I have written a generic routine which accepts an object (in this case a database column) and returns an object which is the data in that column.  The calling routine passes the necessary row and column for the routine to handle. I have written the routine to save having to check for null values individually, however, I need to detect the column type so I can respond to each individually.  For example, if the column is a Boolean (bit) column, I need it to default to 'false' if the field is DBNull.  If the column is a int32, int64, etc., then I need the resultant object to pass back as a "0". I have used the following code, and it seemed to work until I hit a null field for one of the datetime fields.  It was only then ...Show All
