Re: a newbie with a question about .net SDK

The framework and the SDK come with visual studio, you don't have to install them again.

The redistributable package contains only the framework, without the SDK. I think it is included in the visual basic installation - it has to be installed only on other machines to run .net applications.

Hi all!
I’m new to the group; I had a friend in my computer science class tell me about the group. So my problem is this.
I’m building a program for a charity group what they want it to do is take a picture of someone via webcam and then email it to anyone the use specifies a lot like the one at the Microsoft Museum If anyone has been there. So it has turned into my class project. I have ran into a problem with the sending of the email.
The program won’t be using a local SMTP server it will be using one like Comcast (smtp.comcast.net) when I run the program everything is fine until it runs the last line of code and then I get this error message.

An unhandled exception of type 'System.Web.HttpException' occurred in system.web.dll

Additional information: Could not access 'CDO.Message' object.

I was wondering if anyone could help me with it?
I have tried declaring the SMTP server in different areas but nothing seems to work

Thanks for any help

<br />
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
        Dim <big>objEmailMessage</big> As System.Web.Mail.MailMessage<br />
        Dim objSMTPServer As System.Web.Mail.SmtpMail<br />
        objSMTPServer.SmtpServer = "smtp.comcast.net"<br />
<br />
        objEmailMessage = New System.Web.Mail.MailMessage<br />
        With objEmailMessage<br />
            .To = "crazyboutcomputers1@comcast.net"<br />
            .From = txtFrom.Text<br />
            .Subject = "Great Job!"<br />
            .Body = "Want all my money?"<br />
<br />
        End With<br />
<br />
     <big>objSMTPServer.Send(objEmailMessage)</big><br />
<br />
    End Sub<br />

Agen Thanks for any Help

Your problem is that you instantiated an SmtpMail object. You don't have to. SmtpMail is one of those objects that you just use, kind of like a service that's been declared already. Just a little tweak of your code results in this:

Dim objEmailMessage As System.Web.Mail.MailMessage

objEmailMessage = New System.Web.Mail.MailMessage
With objEmailMessage
    .To = "crazyboutcomputers1@comcast.net"
    .From = txtFrom.Text
    .Subject = "Great Job!"
    .Body = "Want all my money?"

End With
SmtpMail.SmtpServer = "smtp.comcast.net"
SmtpMail.Send(objEmailMessage)

This should work for you. Oh! Don't forget the reference to System.Web!

To generate An Autogenerated field

Softtips200420-Dec-03 2:05

I want autogenerated column every time I save Information.
In case i delete a record then,
Eg
The auto generated Nos are 1 2 3 4 5, and i remove 3 and 4 then the 5th record must automatically take the place of the 3rd record(just like what happens in Excel)How do i do it?

Re: To generate An Autogenerated field

Dave Kreskowiak20-Dec-03 2:41

If the autogen'd numbers are the primary key, then you don't get to do that. Once an autogenerated number is used it is never used again, even if it has been deleted.

The only way your going to accomplish this is if you generate the number yourself and keep track of which numbers have been used and which hasn't. More trouble than it's worth...

Thumbnail an html page directly from IE programmatically?

I would like to grab an HTML page from a WebBrowser control and thumbnail it to a picturebox control. Anyone out there know how to do this?

The only way I can see to do this is to use shareware or a commercial product to convert an html page to a bmp, external to the program, save it on disk and then use GetThumbnailImage to thumbnail it.

Thanks, GregC

Since this is a programming forum, maybe you'd get a better response if you phrased your question in such a way that someone who knows how to code well could answer, rather than hoping someone with exprience in a very speific, non-programming field comes along.

Services & accessing file info

I am new to VB.Net so forgive me if this is a stupid question! I am trying to write a service that periodically goes out to another server drive and checks to see what files are in a directory and the file size. If the file size of any given file is zero, it sends an email alerting IT that the backup file size is null. I have set a server timer and have the email portion working, but it will not read the directory. Can anyone give me a direction to pursue? Thanks! Confused | :confused:

The server is a Novell Netware Server(We are a Novell Network with various Windows servers, i.e. No active directory). I am on a workstation that is logged into the network with admin rights and I have a mapped drive to that directory. As far as the ServiceAccount member for the service I am currently using LocalSystem. Thanks!

Dave Kreskowiak19-Dec-03 13:45

OK. LocalSystem doesn't have Netware rights. You'll have to use an account that the service can log into the network with.

Stacy - have you tried setting the service account to the same account that is logged into the (Netware) network ?? it should then be able to use the mapped drive.

(as per the previous comment by Rage...)

The last time I did anything like this we used the ActiveX controls from the Novell developer website to log into Novell seperately and read the directory

I can use arraylist variable to fill datagrid?.

This is my question. Because is not working.

This code must be works?

Re: I can use arraylist variable to fill datagrid?

Well, the DataGrid.DataSource property can take objects that implement the IList interface, so an ArrayList should be fine. Can you post the actual code and exception message you're getting?
