I have downloaded an application that uses .net remoting.
The problem is that I don't know how to configure it to communicate over the internet.
From the blog [url] says to set the tcp 192.168.1.100 . As far as I know this is the intranet IP. My external IP is different. Do I need a server or a Static IP from my provider?
I know that it is possible to download items with Visual Basic [Code], but I was wondering how I could sense that a file had completed its download. (IE: when the download was complete, another event could happen).

The web server is running and I can create a file called "moo.txt" and if i go to the web browser I can see its contents Now, I need to create a vb.net application to communicate with this machine and download that file So far I have tried the following
Code:
Imports System.Net
Imports System.IO

View 1 RepliesI have an application with many things in it, and I have space left for a chatbox. I also have a server which I will be able to use to run the chatroom on.
My problem is: the code I do not know what codes I need to make a chatbox in my application (normal Windows form).
I have a Data Acquisition and Control application that controls at 10 Hz and logs at 1 Hz. Both of those timers call a separate. I recently added a feature to the program to request 6 characters from a server for the barometric pressure. (29.206, etc) It works for the most part, but two weeks ago a computer froze, last week another one froze, and two froze this morning. I have not had freezing problems in the nearly three years this program has been running 24/7. Turns out they disconnected the server this morning, so that explains the simultaneous freezes in two test cells. I used a try catch statement, but apparently that wasn't good enough. how I can make this code more robust?

View 1 RepliesI want to ask how to i do this :
1. Make my application to go to a webpage .
2. Open a certain link .
3. Find & Select an element(mostly element ID or div ID) on a web page like buttons etc.
4. Then extract data from a webpage . Like there's a word for example "Yellow" word in the web page . I need it to find it and copy it then paste into a textbox in my application.
Extra details : I am using Visual Basic 2008.
I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

View 2 RepliesI am creating a client/server application that connects via .NET remoting and I'm using TCP. I have 2 config file for client and server. The config file and the server application runs good. But for the client, it runs even though the server is offline and no port is open listening. I've gone through quite a lot of example and don't really know whats happening. This is my client config file.

View 5 RepliesI currently had a .Net Remoting Application running on Framework 2 under IIS. I have to upgrade it to Framework 4 in order to use some new components. I have been able to set everything up and running smootly on Framework 2, but as soon as I change to Framework 4, I get the following exception when I try to call one of the function of my remote object.
The input stream is not a valid binary format. The starting contents (in bytes) are: 53-79-73-74-65-6D-2E-52-75-6E-74-69-6D-65-2E-52-65
This bug is not the real bug, it is caused by the fact that the remote object is throwing an exception, and IIS wrap the exception in XML, which throws the BinaryFormatter off.See this for more info on the bug.
This is very unfortunate because I cannot see what is causing the exception, and having never used any Remoting before, I do not have much ideas as to where to start debugging. It seems the Exception is thrown before even stepping in the code because I do a fair amount of logging and none of it seems to be triggering.Basically, I'm looking for some clues or pointer from people that encountered similar problems:
What could be causing the exception when no code has changed besides Compiling from .Net 2 to .Net 4?How can I get the full Exception message that is returned?

View 1 RepliesI got two issues getting my application to download a file. One small and one rather big.The downloader seems to have an issue using the users full download capability while the downloaded size is under 1 MB. As soon as it hits that, it seems to speed up with 10-100 times the previous speed.(Snippet at the end of the post)It seems to have to do with the filesize, which is about 5GB. As soon as my application hits about 1GB it completely locks up. (Without an error message, which I do have built in with a try...catch statement)I actually have to force quit the app to make it stop.It works perfectly fine with a 20MB file.I have the idea it's because of the int64's I use. But I need to use those (afaik) due to the big file size.[code]

I have an Addin for MS Excel which needs a singleton to share data amongst modules.Depending on the version of Excel (2003, 2007, 2010), and how Excel was started, it calls my addin from different, unpredictable AppDomains, which prevents the classic singleton approach.Creating a custom AppDomainManager won't work because Excel has already created the AppDomains before the addin is called.
Linking to mscoree to enumerate domains breaks the addin registration process (and I really don't want that anyway); there doesn't seem to be any other way of enumerating, so that isn't an option either.The only solution that I've found is to use remoting. Here's my test rig:
Imports System.Runtime.Remoting
Imports System.Runtime.Remoting.Channels
' Remeber to add reference to System.Runtime.Remoting DLL[code].....
Once everything is running, access to the singleton takes ~100µS, which is perfect. I can live with the ~400mS the first time each AppDomain is initialised. The problem is at startup, where the remoting invocation takes ~2.5 seconds.
