• MyoZaw SmtpClient.Send() problem results in "An established connection was aborted by the software in your host machine"

  Hi, I'm having problems with SmtpClient.Send() where I end with an "An established connection was aborted by the software in your host machine" type error. My infrastructure people tell me that I should have access to the Smtp server so things should just work. I've been googling and searching forums but have yet to see a complete answer to what this error is trying to tell me. Oh and I've tried this in both a Web and a WinForm app on .Net framework 2.0 running on a clean install of XP Pro. Any opinions Thanks Scott.

• thomaskremmel .NET 2.0 Real Time Requirements

  Hi. Probably .NET 2.0 and realt time requirements shouldnt be on the same sentence. I'm trying to control a machine that set's me some real time requirements, the machine fires events,  inside those events I have to do some processing. On one of them I have less than 200ms to performs the work that I need. 200ms is already very thight I cant waste more than 180ms. Per minute I have fired at least 120 of these events I have to handle all of them and can't stay on them for longer than 180 ms. My question is, is the .NET Framework suited to this kind of work Another thing that I must say to help on the discussion, if I waste more than 180ms the machine stops, and that can't happen I really have to meet the time!!! Even if ...Show All

• Rocco Mastrangelo Connecting to Access Database

  Does anyone know how to connect to a access database using vb.net I created the database in access and added the Odbcdataadapter and was able to preview the contents of the database. I have a text box with a next button and a new button. Each time I click next i want to see the names that i have in the database appear. When i click new i want to be able to enter a new name in the textbox and it gets written to the database i already have with the names. Any thoughts Thanks!!

• weirdbeardmt Looking for a way to determine if the return value is used in a ComVisible method invoked through the CCW IDispatch interface

  I've been tasked with replacing an existing unmanaged COM library with a class library written in C# that can be accessible via the CCW to unmanaged applications or referenced directly from managed applications. The main goal for the new class library is to mimic the behavior of the unmanaged Type library being replaced so existing COM\OLE clients can use the new managed type library with minimal conversion steps. Things have progressed smoothly, until I hit the following road block. There are a set of methods exposed by the library that are documented to behave in one of three ways depending on how they are called (from a scripting environment): 1. object.WaitForString ( Text [, Timeout] ) - or - 2. ...Show All

• gon_no1 How can I have one and just one copy of my application running in the same time???

  How can I have one and just one copy of my application running in the same time I did somethign similar a while ago; doing something like this is so popular that I blogged about it here: http://dotnet.org.za/ernst/archive/2004/07/20/2887.aspx What makes it neat is that, if an existing instance of your application is already running, it will bring it to the foreground and maximize it. With the inspiringly named "helper" class (linked to from this blog-post) you're able to write: public static void Main() { bool firstInstance; Mutex mut = new Mutex( true , strSystemMutex, firstInstance); if (firstInstance) { try { Application.EnableVisualStyles(); Application.Run(new frmLogin()); } catch (Exception ex) { Exc ...Show All

• Merie Cockrum Determine the name of the method being called

• Kondas Displaying and manipulating pixels of a non-standard image

  Language: C# I have written a (small) library of image processing functions that work on a System.Drawing.Image object. Works fine for BMPs and JPEGs and PNGs and the like. Yesterday my boss told me the next step is to be able to handle proprietary formats that some of our clients use. All of them follow a basic principle: some header, then pixel values. So to get started the first file format is simply pixel values as raw data. The pixels are stored as 16-bit unsigned words. So I've read a file in through a filestream and converted them to a byte[] the length of the file stream. This works for standard images (like BMP) fine; However I cannot just create an image object from the array of raw pixels. I will need to take my pixel values an ...Show All

• Jon Braganza How can I synchronize two MS Access tables?

  Hello, I have 2 MS Access databases, In each database I have a table called catlog. What I want to do is to check the catlog table in database (B) and pass over each row to see if it (the row) exists on table (A).

• Cygon4 Querying dataset created without connection to database

  I'm building a DataSet in memory with DataTables that are populated with data from an external source (from a COM interface). I'd like to be able to perform queries with a JOIN from the DataSet. Is this possible or does the DataSet need a database behind it to process the query Thanks. The DataTables are populated with data from an external source that is not a database, and then the external data source is released. So the JOIN needs to be performed on the DataTables in the DataSet. It's normal stuff... one table has a UserName and UserID, another table has a UserID and 'other information'. I want to display the UserName with the 'other information'. I just know if the DataSet itself can process ...Show All

Or, do you mean that you want to use VB or C# to query a local drive from a managed app. That's doable.
