View 1 RepliesI am trying to verify connectivity from my application to various servers - For now I am only concerned with mail servers... (later SQL etc)Before anyone gets all upset and thinking this is for SPAM - wrong - these are to confirm connectivity from the application for sending logs OR to ensure the SQL conneciton is working appropriately - Those that want to SPAM can do this simply by getting LINUX and doing it for free with ANY mail client (I add this ONLY because MOST SMTP threads go unanswered... which is silly... there are MANY good reasons to work with mail within an application.....)So what I have tried is opening a telnet session, grabbing the output, and going from there...But it is not working.... the output contains nothing specific to the telnet session I initiate - and.... of course from the command prompt manually i DO get the proper responses
[code]...
I get the command prompt header, I see the commands... I see the prompts... but after the telnet command there is nothing I am assuming there is an issue redirecting telnet info and the telnet session terminates the second I try to read the data

I am using Visual Studio 2010. I want to do database connectivity using VB.Net and MS SQL Server 2005. I know 1 way of doing this. Following are the steps...
1. Create a new Data Source Using Data Sources Window.
2. Select the appropriate view like details view/ data grid view for that data source
3. Drag that data source on your form and connectivity is done. Also all the controls are created by the visual studio.
This feature is really cool but I want to learn database connectivity by pure coding without using such advanced features. Also is it possible to do connectivity from a class library ?

I already made a project using Visual Studio 2010 (Visual Basic) and my database connected to SQL Server 2008 R2, also set up a PC 1 act as a server and the other is client i set this up for beta test.
I'm having issue about putting an IP Address to the server pc, actually if the IP setting of the server pc "Obtain IP Address automatically", i can open my application in the client pc, but once i put IP Address on the server PC i cannot open/run my application to the client pc, i cant figure it out how can i fixed this issue.
I have a simple program that uses this code
Dim sParams as string = ""
Dim emailto as string = TextBox1.Text
Dim subject as string = TextBox2.Text
Dim body as string = TextBox3.Text
sParams = "mailto:" & emailto & "?subject=" & subject & "&body=" & body System.Diagnostics.Process.Start(sParams)

Now I have a table with about 6 email address's in. How would I go about sending emails to each one of these emails in the database using this code. User can also add emails to the database.
I need to make an address book that doesnt use a database.It suppose to have [code]All information shall be stored in a structure at run time.The application should read and write to a data file.Make sure the application includes previous, next, add, save, and delete buttons.When graded by your instructor, there should be at least five entries in the address book.But the book doesnt show me how to do it and the only online stuff I can find is threw databases and nothing else. I asked the teacher and he says no database for this one, the idea is to use flat files (txt) and I have no idea how to even really start this one.[code]

In my VB.Net app, I want to read in a load of addresses from a database and then use word to create address labels on an Avery template L7163 which is then printed to the printer.
However, I have two issues:
1. Before word prints, I'm asked to select the printer etc. not exactly the nice automated application I was looking for.
2. Even though I get a nice printed out doc I was looking for, I also get a nasty looking error at the end which "loops" until I close my app -2147417848: The object invoked has disconnected from its clients. (Exception from HRESULT: 0x800010108(RPC_E_DISCONNECTED))
