Before going into production, our client demands actual numbers of how many users our web application can handle.
We have all kinds of features implemented including asset management (file uploads/downloads), documents import/export, various statistics, web-services etc.
I guess we need tool which could emulate users form submission because documents import/export as far as I noticed is the slowest part of an app because of parsing and generation.
Which tool (or set of tools) could do this?
Application details:
XHTML/jQuery
Coldfusion 8
SQL Server 2008
Windows Server 2008
I like jMeter - free software and does the job quite well.
Few intro screencasts:

HPs Open Source HTTPerf I like. Just setup the URLS you want to test and let it rip. use a couple of machines to emulate load. You could even parse the output into a DB and do some number crunching.
Also, think about doing HTTPerf runs with profiling on the server side to see what lags and what doesnt. A nice touch is to let a user go on the app, and record all POST/GET requests and use them as a replay set for typical user interactions.
Also, if you are thinking about UX, use firebug or something to check JS imports are being done asynchronously instead of one-at-a-time. Have a ganders at Stackoverflow question 310583/loading-javascript-dependencies-on-demand

WebLoad: Professional and open
source load testing from
CFMeetup
Visual Studio Ultimate edition has great load/stress testing tools, although the ultimate edition can be a bit expensive.
m using Full version of JBlitz Professional 5.0 ..
it's very good
There are few analytical performance tool out in market(not free) one i came through and works well is New Relic. If you are looking only to test the api then http://locust.io/ is good one and free too.

Does anyone have any recommendations for good vulnerability testing software for c# window forms (not .net) applications.
Preferably one that can also test with a mysql server or sql server connection.
There is no tool that is going to match a good code reviewer or penetration tester. But a few tips to get you aimed in the right direction:
Static analysis tools like HP Fortify, IBM AppScan, and CheckMarx do a wonderful job at finding security issues with code. But you really need an experienced code reviewer to get the most out of them. Also, they are not cheap! These tools operate by scanning code, and the main requirement is to provide to the tool everything you need to build your software (at least this is the case for Fortify and AppScan, not sure if the same requirement holds for CheckMarx).
IAST tools such as Contrast are also not cheap. However at least in the case of Contrast, they are specifically trying to make it more developer-friendly. IAST tools work by hooking into your binary in your test environment and looking under the hood for bad things that happen.
Dynamic analysis tools such as OWASP ZAP (free) and Burp (not free, but affordable) can run automated scans in your environment, but if you lack experience with these, then your value is limited. These tools work by scanning in a test environment and sending malicious payloads to see how the server responds. A lot of effort is being put to make ZAP work in continuous integration build environments.
All of these should work for the technologies that you are using.

I am developing an dashboard application which will give insights of the data of an organisation. I am confused as to what will be the best approach in developing the Dashboard:
a. Should i go for Crystal Reports
b. Should i Use WPF Charts and display Data
Any suggestions please which help me go ahead with my design?
Regards
Vineet More
It depends on your goals.
Using WPF and charting controls will likely be simpler to deploy since it's a client application (you won't have to worry about Crystal being setup correctly). They come with the framework and won't have any additional upfront costs and it should run seamlessly across workstations.
Crystal is nice though especially if you want to send the output to the printer as a report (this is where it's roots are and it excels at it). It's a pain to deploy locally and even more of a pain to deploy on the server (where it uses the C:\Windows\Temp directory during the report export process which you probably won't have access or permissions to on a server in the cloud... or have access to the registry to change that location).
Another option you can consider is using HTML and JavaScript with a 3rd party charting library like d3. You an render the content from your client app in a web browser control and make it look seamless with your app. This approach would also make it easier to move it to the web if you ever wanted to render it from a ASP.NET site (or really from any web language).

Hi I have been given a task to design tool to monitor database server health like cpu usage, memory usage etc. Now there is one such tool like MySQL Spotlight. I want to know is there any open source software available with same functionalities? I want software which has nice visualization with charts. Please guide. Thanks in advance.
You could use Cacti for this. Also look at Nagios.
Check out http://code.openark.org/forge/mycheckpoint. It is an open sourced monitoring tool, primarily for db monitoring, even including custom queries and custom alerts! Graphs come pre-packaged and pre-generated. It's written in python, so mods can added to the code easily. I've used it a bit, and it seems to work pretty well. The only caveat I see is the extensive schema that comes pre-packaged which, ostensibly, can't be customized. One thing I will note for the email alerts, if you're getting login or credential alerts, go to line 4338 of the code and just add what you need to the smtplib.SMTP instance.

I've almost completed a Windows Application (Windows Forms) project for a client, but one of his requests is to have the typical "?" menu item that opens an help file with a User Guide help.
I know how to build documentation based on Documentation Xml (and I did that already), but this is something different: it must be a User Guide, something that the end-user will understand (he doesn't care to know anything about the code behind the application), with screenshots, HOPW-TOs, FAQ, etc.
User must be able to always open it (so, a web site or anything that requires an internet connection is not an option).
I was thinking to use an actual help file (msha + mshc files?), but since I only know how to build it from Documentation Xml, I have no idea of how I can create it and how I can make it shows from the Windows Application.
Any hint?
You could create a windows help file with this: http://download.microsoft.com/download/office97dev/helpws97/4.03/win98/en-us/hcwsetup.exe
This is a help file creator application.
Creating a .chm/help file that can integrate itself in your application from XML mark-up embedded in code (or otherwise) is never going to be a straight forward matter of conversion. I would suggest looking into the following tools (although they are not free, there may be alternative free tools available):
Doc-to-Help We use this and it can convert a Word document directly into a .chm help file.
Help+Manual
HelpSmith
In addition take a look at this question
What tools are available to create a help file in Visual Studio 2010?
It has some very useful answers and may provide exactly what you are looking for.
I hope this helps.
I haven't used it yet, but HelpPane might be what you're looking for. It's the replacement for CHM as of Windows Vista.
One thought would be to build a self-hosted ASP.NET site, so that you can use Master Pages for your consistent look-and-feel, and then point a HelpPane instance to that site.
With a little bit of digging I'm sure you'll be able to find a suitable library for self-hosting an ASP.NET site.
EDIT1: Also see this SO topic.
EDIT2: It seems that HelpPane.exe will only display Windows help topics. Perhaps this will be better suited for your needs. HTH

I have the following scenario. I need a db to store XML messages that have been created by a reader. I then want to use a transport (wcf) to read the db external to the populating app and send the messages to a central db Generally the db needs to run on mono, and windows.
I did look at sqlite3, and it seemed to fit all my requirements, but i'm reading its not so good on multi process access and t's moving away from my sweet spot, these last couple of days.
Thanks.
Have you considered just using XML to store the data? It doesn't get any more portable than that and will work fine as long your client-side storage needs are simple. E.g. not a large amount of many domain objects that need to be stored.
Additionally using an XML data store solves a lot of setup and installation headaches. You simply reference a file (or files) relative to your executable. You don't need to worry about installing db engines for a variety of platforms and then worry about upgrading.
WOuld it be feasible to give each process their own sqlite3 database? They all ultimately use the central database anyway, right?
Have a look at Firebird.
You can use it as an embedded engine just like SQLite, but it can scale to a full blown server as well.
The only drawback is, that the documentation is a mess
