Check this[^] out. If you want a non-Express version, then you will have to buy it.

I’m working on developing a simple WPF application that will need to get its data source from a SQL2005 Database. The question I’d like to ask however is what would you consider to be the most appropriate Database connectivity for such an application?
(The application is geographically local to the server and serving several dozen simultaneous users (later in the development cycle). The application will be using touch screen technologies and the application its self will be deployed as a click-once application)
Here are a few of the technologies I’m considering, and what I see as their pros & cons:
1, The application contains it’s own CLR to connect to the DB:
Pro: Simple
Cons: Doesn’t scale well, each application will have it’s own separate connections
2, MS Smart Client application framework:
Pro: readily available, well documented, proven to work, scalable
Cons: Complicated, weighted down with stuff I neither want nor need
3, Remoting, using remote CLR objects:
Pros: simple and readily available
Cons: Not well accepted as best practice coding for this type of application
4, Application uses XML web services:
Pros: relatively simple, scales well, very well accepted & documented
Cons: Hmmm… can’t really think of any show stoppers
I’m tending to lean towards number 4, but I’m open to suggestions, the project is just starting up, we have no baggage to carry and I have an open slate… Coding nirvana!
So my question remains, Can you think of any more methods? And can you think of a reason I shouldn’t be using number 4?
Thank you all for your Guru-like help

Do use "split" function and take the one before the last item in the returned array.

Hi
I have an asp.net application. whenever i compile or run my application it's create extra .temp files, then i have to delete that files again and again. Would you please tell me the reason why it is creating this file and how can i restrict this.

asp.net has to compile your code to run it (creating dll of your files)
and then it can run the app you can try to pre compile your app this might help
Please tell me if I am wrong

basically temp files are created in C:\Windows\Temp and it contains file inforamtion about all the web pages that the browser opens, well i am anot very sure whether you can really restrict this from happening. One way out is to go to Tools->Internet Options and go to Temporary Internet Files and delete all temp files from there or write a simple code in ur web app to delete those files on the exit of the application automatically.

|
|

actually when i compile the application it's create the temp files and add into the solution.

 Hi,
I want to restrict a class to not to have more than 5 objects of that class.
kindly revert me a good solution.

Use a factory pattern that creates only upto 5 instances. When your object is disposed, decrement the static reference count.

thanks ravi,
but my question is how to restict the user to create the next instance. The code for the the same. I am using C#.net
|

He answered your question. I imagine the fact that he didn't post the code you are not happy.
You want only 5 instances of class A.
Create a factory class AFactory.
The user of your code calls
AFactory.GetNewClassA(). In this class you have a reference coutner, which counts how many instances of Class A have been created. If this counter is less than 5, create and return a new isntance of Class A and incretment the counter. If it is already 5, don't create a new instance.
You can also do this as a static Create method on Class A, using a static reference counter. Google for Factory Pattern.

Hi all,
I'm new to C#, but have a complex situation here. I have a c++ code that need to be converted to c#. The c++ code stored a data in BYTE type..e.q of c++ code:
BYTE bGMPCName[81] = ""; char cGMPCName[81] = "";
long status = JPN_GMPCName(bGMPCName);
memcpy (cGMPCName, bGMPCName, 81);
AfxMessageBox((CString)cGMPCName);
From what i know c# doesn't support 'memcpy' function and i also have a troublesome to read the string in c#.
I've read something on 'MemoryStream' but still don't understand how it works.
Your help is really needed
Thanks

Hi
i need a file viewer can open images ,video ,audio ,pdf ... formats .
How can i find the source for it in C# or component only?
Thanks and sorry for my bad english
please Help me...

Probably google.
You sound like you want to write a program that has a Windows Media Player control in it, a picture box, and also embedds Acrobat somehow.

I wouldn't bother, that sort of thing is handled well enough by Windows Explorer.

I'd recommend a site called Code Project. I hear that folks sometimes have examples on that site that you can download and look at the source. You should check there. 
Definitely it isn't hard to view an image file - PictureBox will do that. Video and Audio can be viewed using the Quartz plugin or the MediaPlayer plugin. I suspect there is a PDF viewer too, though I haven't bothered looking for one.
Good Luck!

I've written a Windows Form application and am trying to adapt it as a command line utility.
Target Behaviour:
1) When I run by double-clicking the exe it runs as a windows application.
2) When I open a command line and execute it without params it opens as a windows application.
3) When I open a command line and execute it with params it runs as a command line tool and outputs to the console.
What I'm seeing:
If I define the project as a Console Application then my form displays, but it also opens a console in the background. This is ugly.
If I define the project as a Windows Applicaiton then it accomplishes 1 and 2, but doesn't output to the console for 3.
Here's my entry point code:
static void Main(string[] args)
{
if (args.Length > 0)
{
CommandLine.Run(args);
}
else
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Main());
}
}
What am I missing here?
If I need to define the project as a Console Application how can I supress the console? (sounds hoaky, I know)
Thanks,
Shaun

I've done that. Start out as Console and use the FreeConsole API function when you want WinForms.
