For those new to message boards please try to follow a few simple rules when posting your question.
Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
I have a vb.net app (.net 4) which writes serial data (no more than 10 bytes, via System.IO.Ports.SerialPort) and there seems to be a delay in the send. An external device tells me to do something. It takes my program about 15ms to process this request and send the result back to the host. The host is timing me to see how long it takes. I can guarantee that I am sending the serial string within the 15ms, but the host doesn’t get it for 80ms and some times as much as 150ms! What external force is causing this delay? I was original using a USB to serial adapter but have since switched to a PCIe card and am getting the same results.
None, it is caused by the design of Windows. See here[^].
You application is not the only one running, and you cannot guarantee your call will be within 80 or 150ms, as Windows is not a realtime-OS. That way other applications (like from some companies that like to preload their reader) cannot use up all resources.

Ask it under ASP.NET forums, they would say "ASP.NET is the best!". Ask it under PHP forums, they would say "ASP.NET is the worst!"
So it just doesn't make any sense at all as the choice is yours to make. You can surely Google for it and ask about the features and services provided by each of the framework. You will get the idea yourself.

I have installed microsoft visual studio on windows 8.1.
Windows 8.1 had already got 4.5 ,3.5.
I have followed all the steps of IIS .
While creating ASP.Net website ,once I give the name and click Ok to start working ,I get this msg box:
"ASP.NET 2.0 has not been registered on the web server. You need to manually configure you webserver ASP.NET 2.0 in order for your site to run correctly."
how to do it manually?
I have started learning ASP.Net Web application.
While saving first project ,it should show localhost name in the **location ** field.
But it shows normal project folder present in C: path.
I have also set up IIS Services.
OS is Windows 8.1.
ASP.Net is 4.5 and 3.5 also.
When I try to run inetmgr in run command ,it shows "Windows cannot find inetmgr .Make sure you typed the name correctly".
Please tell me the solution.
For each drive you have, type the following into a command prompt
dir /s inetmgr.exe
This looks for the inetmgr.exe file and will tell you where it is located, if it's installed. To be honest, it sounds like you haven't actually installed IIS. You might want to try downloading and installing IIS Express instead.
Dear Friends, Can you suggest the options for Exception and Performance Monitoring tools for .Net Applications. Back in 2010 I had used AVI Code Intercept Studio, which was a great tool and helped to a great extent discovering bottlenecks and un-handled exceptions . Since AVI Code is taken over by Microsoft it is now available only as a part of Microsoft System Center 2012.
I want to consider a tool which can be used in such a landscape where most of the servers are with Windows 2000, 2003, and 2008 and with applications ranging from .net framework 1.1 to 4.5.
The primary intention here is to monitor the exceptions rather than performance.
While searching on the net I came across this... but never knew about it before
Not at all my friend... This surely not an ad.
I have posted this question on various other groups.. but didnt get any answer so far.
I am part of a big DR implementation project...of such an IT landscape which is pretty much f***ed up already...70% being on .net platform but most of it 1.0 or 1.1 framework and on old OS... windows 2000 or 2003...with no proper documentation and standards for instrumentation and logging. I want to make sure that bringing up the applications in DR site is going to be as smooth as possible.
