• Visual Studio Express Editions Submitting a Form over the Web

  How would I have the data that users input in a form be submitted to me say over an e-mail.  If you can not do this over an e-mail, could you please tell me how this would work. This is very important!  Thank you all. you can use the System.Net.Mail classes to send an email to a specified email address however you must generally give it the Credentials so it can authenticate your account. you would use a MailMessage object to construct the email (sender, to, subject, message etc....) then use the SmtpClient class to send the email, of course giving it the IP Address of the mail server/SMTP server.

• Visual Basic Having some trouble with Webbrowser manipulation

  I am trying to write a program that will go to a webpage, select a specific item from the pull down in a form, enter something in a text box, and then hit the submit button. I have been able to enter stuff in the box and click the submit button but I can't for the life of me figure out how to select items from the pull down. Can anyone give me some example code or something like that Thanks! I think that was exactly what I needed! Thanks! This needs to be documented somewhere as like an example or part of a tutorial because I could not find it anywhere. ...Show All

• Visual Basic Passing an array from a VC++ ActiveX component to VB .NET 2005

  Please point me in the right direction if this has already been answered. I've looked all over and found things close to my problem, but nothing that adapted properly. All I want to do is pass a one-dimensional array from an ActiveX componenet written in VC++ (2003) to a program written in VB .NET 2005. It seems like I should be able to package the array as a Safearray and then as a Variant, and return that object. But I don't seem to be able to package it properly. Thanks! That is correct. I am creating the array in the C++ code and trying to use it in the VB code. I'm afraid I'll confuse you by posting my declarations, because the only method I could find that might work would be to create the ar ...Show All

• Visual C# Recursive Hierarchy of generic interfaces

  I'm trying to implement a parent-child relationship between 3 objects, and I want to constrain what can be a parent of what. interface3's parent can only be interface2; interface2's parent can be either interface3 or interface2 interface3 -> interface2 -> interface3 -> interface2 -> ... -> interface2 -> interface1 As a first step, I tried to implement an interface hiearchy that only allows interface3 -> interface2 -> interface1 I thought the following interface definitions would do it, but the compiler complains that The type 'interfaces.Interface2' must be convertible to 'interfaces.GenericInterface<interfaces.Interface2>' in order to use it as parameter 'P' in the generic type or method 'interfac ...Show All

• SQL Server Snapshot Agent missing files.

  My Snapshot Agent for SQL Server 2005 sometimes does not fully complete. I am expecting around 2073 files in the snapshot folder but only get 492 (this number does change). I have immediate_sync set to true, so I should get a full snapshot every time. It seems to quit after all data has been BCP'ed out and before the schema generation starts. I do get the " The replication agent has not logged a progress message in 10 minutes. This might indicate an unresponsive agent or high system activity. Verify that records are being replicated to the destination and that connections to the Subscriber, Publisher, and Distributor are still active. " message in the MSSnapshot_history table.

• Software Development for Windows Vista Exception on raising an event

  Hello, I'm developing an example project very similar to expense reporting (lab01), with two event handlers. I can fire the first one (submitted event) without any problems, but when I try to raise the second event (reviewed event) I get an exception that sais: "EventDeliveryFailedException was unhandled" and the message is "Event "RevisatCOF" on interface type "WorkflowValidacio.Interficie" for instance id "ef46e5fa-64c7-4343-9d3c-c62b829f9c37" cannot be delivered."

• SQL Server run-time changeable queries

  I need to extract and store a value from a table (or from a MS Access file with OpenDataSource) which is not always the same and it is therefore stored in the @openfile variable. Something like this: ... declare @standardselect nvarchar(4000) declare @value int select @standardSelect='select top 1 @value=val from ' + @openfile exec (@standardSelect) ... It obviously doesn't work because the variable @value is not declared within the sql string. However, since @openfile is always different, I need to pass it through a string and the only way I know is within a variable. If I declare @value inside the @standardselect it is not accessible to the rest of the procedure, which is not acceptable for me. Any suggestions ...Show All

• Visual Studio Team System Disable multiple checkout

  We are experiencing some problems with multiple checkout. I want the exclusive lock behaviour, so I unchecked "Team->Team Project Settings->Source Control->Enable multiple checkout". Unfortunately we still have one class diagram file that seems to work in multiple checkout mode. I do some changes, my coworker can do them in the same time and when we check in we get conflicts. Any hints on why this happens Is it possible you or your coworker already had the file checked out prior to changing the Team Project setting When you check out the class diagram, does the pending changes window show the pending change as "edit,lock" or just "edit" Thanks, Ben Ryan ...Show All
