In ASP.NET the tilde at the beginning of a path represents the local file system path to the root of the application. Without it you'd have no way for the server to reliably access the local file system relevant to the application. So, for example if I have an ASP.NET application on my local machine named "TestApp", when I call Server.MapPath("~"); I would get something like "C:\Inetpub\wwwroot\TestApp".

First you should be very careful when you use GDI+ combined with ASP.NET.Microsoft warns that some GDI+ features may will cause some unexpected problems when are used with ASP.NET.
Why don't you write your own HTTP HttpHandler that handles images load from the database for example?
Life is a stage and we are all actors!

Along the lines of the other recommendations, taking the image data and constructing a Bitmap of it seems to be extraneous. If you have the image data already, then there is no benefit in using that data to construct a Bitmap other than being able to invoke Bitmap.Save(). All you really need to do is write the data directly to disk:
using (FileStream fs = new FileStream(Server.MapPath(@"~\UserPhoto.bmp"), FileMode.CreateNew))
{
fs.Write(Data, 0, Data.Length);
}
This also has the benefit of removing GDI from the equation. So, if you still get an exception you will atleast be able to catch it as some sort of IO Exception and get more meaningful information about the problem.

Hello,
I am trying to use speech recognition in my application it works fine in vista but when i try to run in xp it gives me error "value does not fall within the expected range".
My code is:
SpeechRecognitionEngine rec = new SpeechRecognitionEngine();
rec.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
DictationGrammar newgram = new DictationGrammar("grammar:dictation#Spelling");
rec.LoadGrammar(newgram);
rec.LoadGrammar(NewGrammar("Greeting", "Hello", "Morning", "Good Day", "Hi", "Sup?","Up"));
rec.SetInputToDefaultAudioDevice();
rec.RecognizeAsync(RecognizeMode.Multiple);
private Grammar NewGrammar(string RuleName, params string[] Phrases)
{
Choices GramChoices = new Choices(Phrases);
GrammarBuilder GramBuild = new GrammarBuilder(GramChoices);
Grammar Gram = new Grammar(GramBuild);
Gram.Name = RuleName;
return Gram;
}
void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
label1.Text = e.Result.Text;
}
I have installed sapi5.3 in xp too. This is developed in vs2008.
Please help me for this i have googled for this but failed.
Thank you in advance.

Thank you for your reply,
rec.SetInputToDefaultAudioDevice(); this line is generating an error.

Are you absolutely sure that the Windows XP machine is at least running Service Pack 2?
Also, put a try/catch block around the code and see if the inner exception gives you more info.

Yes
Application is running on xp sp2, vs 2008, sapi 5.3.
And on vista there is vs 2008, sapi 5.3 and it works fine.

I found this:
System.Speech only works with a pre-defined list of words or phrases;
Maybe one or more of your phrases are not supported. My guess would be "Sup?".

Look at this MSDN thread[^]
BTW, I found this with this google search phrase:
C# SpeechRecognitionEngine Windows XP + "value does not fall within the expected range"
Essentially, it's a threading problem that is exposed only in a winforms application running on XP. If you put the same code into a console app, it will not throw the exception.

Hi all,
I would like to know if any of you have worked on syncing data between SQL server and Velocity (Distributed cache application developed by Microsoft).
The requirement is, currently I have SQL server database with some core tables (5 to 10 tables). One application frequently queries data from these tables (Some other application inserts/updates data in these tables). We are planning to replicate these tables to Velocity datastore and the first application queries data from velocity (where as the second application continues to insert/update data into SQL Server database). Now I need to find a way to synchronize data between Sql database and Velocity data store.
Any pointers on this would be of great help.
Thanks,
Ganesh

Hi
I'm running an open source web server (CASSINI) and on top of it I've implemented WebDAV functionality which is working good. When I'm trying to mount that as a virtual drive in my local machine it is not allowing me to do that.
Is WebDAV only meant for IIS ? IS there anyways to incorporate with my open source webserver...
Thanks ...

Hi,
I need to implement a timeout expression.
Forexample like in services there is:
TCPIPServiceController.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(0, 0, 10));
Where it checks for 10 sec whether the service has reached a running state, else exception.
What i need is a customized similar expression (one line) implementing timeout, where i need to check the state of a variable, if true then carry on else exception.
I don't wish to implement standalone timers event for that...., as there are many methods in which i need to implement this.
Hassles of Async programming!!!.
Any help please!!!
Thank You.

I believe the System.Threading.Timer class should be able to handle this in relatively little code. This version of the Timer class takes a TimerCallback delegate that it will invoke after the specified amount of time has transpired. You can also configure it via one of the constructor overloads to continue running at a certain interval, or you can have it run only a single time. Last, it takes a state object so you can pass in some data pertaining to the operation you wish to check and that object will be passed in to your delegate. Here's some example code just to illustrate how easy it is to use.
using System.Threading;
...
private Timer _operationTimeout = null;
private void CheckOperation(MyOperationData data, int timeout)
{
_operationTimeout = new Timer(new TimerCallback(CheckValue), data, timeout, Timeout.Infinite);
}
private void CheckValue(object data)
{
MyOperationData opData = (MyOperationData)data;
if (!opData.Value.Equals(opData.ExpectedValue))
throw opData.TimeoutException;
}

Hi Experts
Can You Explain When We Have To Use The Interface Collection.,
and what is diff. between Simple Collection And ICollection.
and Generic Collection in C#.NET
Dinesh Sharma
|

|
|
|
ICollection is an interface that extends IEnumerable [^].
Generic collection classes provides increased type-safety and in some cases can provide better performance, especially when storing value types over simple collections. Good link here on when to use generic collections.

I'm taking a brief break from my Recloser project to try a custom control. For many years I've wanted to build a scheduling app that actually works, something like Project, except that it would be usable. The stumbling block was always in developing a nice Gannt chart control with the little triangles at the edges, a rectangle to show the task duration, and a contrasting rectangle to show progress, all of which had to be draggable (yeah, I know that's not a word, but it works here). For a decade I tried with MFC to do it, but remain stumped; the GDI+ functions in the .Net Framework seem ideal for the task and I've been reading about them. I need a break from the other task, so I started this one tonight.
I've got as far as creating a container, sizing it, and populating it with the graphical elements for the display. Tomorrow I plan to start trying to Draw the elements and maybe delve into mouse interaction a bit. But I'm stuck on a proper approach. I see a lot of controls that can be resized at runtime, and the visual elements change size or positions as the mouse moves. I have a fair idea how to make the elements change one time - after a drag - by recalculating all the parameters on a Mouse_up event. But I don't have any idea how to implement a method that continuously updates the screen as the item is dragged by the mouse.
Can someone point me to a tutorial or example of implementing this behavior?

Hello, how do drawing windows form manually?
how make form Class?
Visual C#
thanks 
|
|
|
|
|
Are you and Hakaxxxx in the same class? Or did you create a second user name thinking it would speed up getting an answer to the exact same question?
I'm not clear about what you mean by drawing a form manually. I usually use a pencil - a HB lead is best - to do this, long before I type any code.
As for making a form class, it would take far less time to type "Windows Form Class" in the Google search box than it took to write this question, and you'd find much clearer answers that way.
My guess is that you have an assignment to create a Windows Form class, and you don't have Visual Studio. That means you have to create source files in a text editor and compile them with the free C# compiler in the SDK. That's definitely the hard way, and I can't help you with it; I'm a beginner myself.
But Visual C# Express is free to download, and I recommend you do so. If you need to show the source code to your teacher, I suggest cheating. Build the project with the proper tools, then copy/paste the code into a text document.
Good luck!
