Best Way For Concurrent HTTP Connections?
Apr 22, 2010I need to download a bunch of pages from a web server, ie. spidering. I know that servers are typically configured to only allow a couple of concurrent connections from a given IP, but that would already halve the total time to run the script instead of downloading one page at a time.

Get Background Workers Use To Make The Connections To The PLC's?
Feb 23, 2010For my project I connect to a large number of variables in multiple Beckhoff PLC's. I connect to the PLC in the Form load event.But the first time connect to all plc's taking too long.The data from the plc's. be sent to my program can not cope with the private sub OnNotification. This is because the program is busy with making connections with various other plc's.If the program is fully launched it works ok, but I also want to start working properly.I solve it just with a timer and a counter. Each program cycle I make a connection, the next cycle the next etc.until all connections are made. This should be better.I would like background workers use to make the connections to the PLC's. bgworkers provide the connection.The main program is not blocked, and the incoming data from the PLC's can be handled properly In the form Load event I start the bgWorkers containing the code for connect and AddHandler. Unfortunately it will not work this way?

View 1 RepliesUse A DB Queue To Make Http Calls And Update Status In Db?
Feb 28, 2012I want to use a database table as a a queue...but the processing of these messages cannot be done from the database.I have a table that stores the requests i get from a .Net component. I now have to read the data from these tables and make http calls to 2 webservices. Based on the response received from the webservices, the data gets archived or deleted.I had a few specific questions:
1. How do i make sure that if i pick a record for processing and the http call fails I should be able to go on to the next record, and then come back to this record at the end of the run
2. Is there an alternative to using the database as a queue(like MSMQ etc.), which option is better
3. I want to maintain an audit trail of the record status. Is creating a trigger to log the changes before the edit the best way to do it?

View 1 RepliesClass Libraries (.dll's) Referencing Other Class Libraries (.dll's)?
Dec 17, 2010I designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?
Make The Http "POST" Request To The Specific Spot?
Mar 18, 2011I am trying to write this program that logs into this website. Now I figured out how to make the http "POST" request to the specific spot on the page which returns a "Successfully logged in" afterwards but once I make a request to another part of the page, it asks me to login (I look at the source code). I have been messing with Fiddler and I compared the a POST from my webbrowser to a POST from my program. I found the following lines to be in my browser POST and not in my program post:
[Code]...
I am assuming this has something to do with the cookie that I am suppose to get to be able to tell the website that I am logged in. If someone could point me in the right direction that would be great. I dont use XMLHTTPREQUEST in my program. I found it earlier on the msdn website but now I cant find a reference to it.I am also not good with term names and I just started learning VB and don't know much about cookies/HTTP requests and such, but that is why I am trying to learn.

View 10 RepliesC# - Using Two .NET Libraries With The Same Namespace?
Apr 11, 2009I'm currently maintaining some old code for a company. As it would happen, the current app I'm modifying uses an older version of the in-house library (we'll call this Lib1.dll). They also have a new version of the library called Lib2.dll that improves upon the previous library in many ways.
Unfortunately, Lib2 is not backward compatible with Lib1. What's worse is that they both use the same namespace Product.Common.
How do I use Lib2 and Lib1 in the same project? Right now if I add references to both of them, VS tells me that certain classes are ambiguous (which makes sense, since they using the same namespace).
Basically, I need something like:
Imports Lib1:Product.Common.Class
I'm using VB.NET 1.1.
Class Libraries (DLL's) In .Net?
Dec 3, 2009I'm creating an application that will utilize a lot of functions for performing scientific calculations. There will also be a lot of 3D and 2D rendering in my application. Hence i will have a lot of common functions that will be utilized frequently.
I have noticed that class libraries (DLL's) are utilized in applications similar to mine, and am wondering if i should utilize them in my application. The trouble is, i can't really think of what use they will be to me. The functions in my application will only be called upon by my application, so i do not need to make my functions accessible to others. The only other benefit i can see from using DLL's is reduced memory usage and .exe size.
Whats the benefit of using DLL's instead of just creating a bunch of modules in my application to store my functions? I have read that another benefit of using DLL's is they are easier to maintain and update as you can update the DLL rather than your entire application. I dont quite understand this, as if you are going to utilize new and updated functions you have added to your DLL's, then you will need to update the code that calls them as well. So again i don't see the benefit in using DLL's in my application.

View 1 RepliesDotNET Native Can Use Instead Of One Of These COM Libraries?
Nov 1, 2010I'm looking at a small remoting project in VB.NET. Initial research turns up references to msrdp.ocx which my Windows 7 Ult system doesn't have; a filesystem search on the same platform turns up MsRdpWebAccess.dll which doesn't appear to be well documented; finally hunting through COM references in Visual Studio turns up rdpencom.dll labeled "rdpcomapi 1.0 Type Library" which seems to be best documented via personal developer blogs (which isn't encouraging but is a lot better than other options).
My goal is a lightweight remoting application I can deploy to Windows 2000 Client/Server, WinXP x86/x64, Win2k3 Server, Vista x86/64, and Win2k8 Server.Is there anything DotNET Native I can use instead of one of these COM libraries? Is one of these COM libraries better for the job overall than others; and then am I going to have platform-specific compatibility issues if I don't provide support for more than 1 of them in my app?
Exceptions In Class Libraries?
Dec 6, 2009I'm creating a class library that contains a series of functions with Try...Catch blocks to handle errors. When i run another application that uses the class library, and call a function in the library using parameters that i know should cause an error (i.e. divide by zero), i don't get an exception thrown.
Can you not use Try.. Catch blocks in external libraries? If not, how are you suppose to handle errors in these functions?
Free Libraries For The .NET Framework?
Jul 27, 2009I was wondering if you could tell me of any free libraries for the .NET framework (2.0) that you know of that can convert a PDF file to HTML or XML. I've seen several components that do the opposite, meaning HMTL to PDF, but not what I need. Essentially, I need the html version of my PDFs because I need to search through the text. Also, the Adobe Acrobat SDK is not an option for me, even though I know it has the exact functionality I need.

Aug 31, 2009I've just about finished my WPF app, but I just hit a hurdle: my app needs to be totally localized (I've achieved this using databinding/RESX files & multiple cultures), and the actual program does this My problem is that I have a window where you generate reports on your progress.It's designed so that programmers will be able to design their own 'report sections', using interfaces & class libraries.Just one problem though: when I use RESX files inside these class libraries, they won't actually change even if I set their culture to the relevant culture I want to test.

View 2 RepliesAdding Folders To Libraries - Windows 7?
Feb 19, 2012At my workplace, we're having troubles with Windows 7. Folders that are supposed to be in the libraries (e.g. Documents Library) aren't appearing. While we sort the issue out via Group Policy, I'd like a "DIY fix" that people can run and keep working instead of flooding IT support with requests. From snooping around, I've found that the folders are stored in an XML file here:
[Code]...
I can edit it by hand or programatically, but there is a node called <serialized> which is a long string of alphanumeric characters. It's not necessary (I can manually add folders without this and it works fine) but I was thinking there must be a better way to go about this, so my question is:
Is there a VB.NET function or class that lets me add and query folders in the library without manually creating the XML and inserting it myself? I'm happy to do it myself, but if there is a better way to go about it, I'm all for it!
C# - Burn A (Video) DVD In .NET Without 3rd Party Libraries?
May 4, 2011Maybe this is a stupid question....I'm looking at a project that would require me to burn a video to DVD in such a way that a traditional DVD player could play it. I've found several '3rd party tools' that do this, which is great and the direction I'll probably take.
But, I can't, for the life of me, fathom how to sit down and write a video to DVD. I know this is largely academic (Just use the available libraries!) still, I'd really like some direction on how I would/could go about doing this myself.
