What do you mean ? How is the value ever not 'exact' ? How are you hoping for a delegate to help here ? Either way, you get the value when the event is fired, it's the only value you're going to get.

how do i change any date and time format to current computer datetime format.

What are you asking ? Doesn't the DateTime class automatically format in the current locale settings ?

Use the convert.datetime and pass the IformateProvider information... You should be able to resolve the problem

This is the C language.
In C# it would be

using System;

public class HelloWorld
{
public static void Main()

{
Console.WriteLine("Hello World!");
}

}

Do you know how to write this hello world program in the C language,but in Visual Studio 2005 ?

Thanks a lot

In c i used to write Hello world.

<br />
#include <stdio.h><br />
<br />
main()<br />
{<br />
  for(;;)<br />
      { <br />
          printf ("Hello World!\n");<br />
      }<br />
}<br />

But in VS2005 you try as how CG said.

C++ is a language built on C. You can create a C++ project and put C code into it. You can change the file names to .c from .cpp to get the compiler to force it to be C code and not C++.

C# is a completely unrelated language that uses the C in the name to indicate that it's syntax is somewhat similar to C++. Use the Visual C++ forum for C questions if you have them in future.

Good luck !!

(You have to watch your less-thans and greater-thans when posting here.)

#include <stdio.h>
main()
{
printf("Hello World\n");
}

Anyway, I did
Start|Programs|Microsoft Visual Studio 2005|Visual Studio Tools|Visual Studio 2005 Command Prompt

Then I used Edit to write the "Hello World" program and used cl hello.c to compile it.

But that's just me.

triggering the playing of a WAV/MP3 from an audio source (e.g. microphone)

13-May-07 17:43

Go to File/New/Project. You have to create a project to be able to compile it. Create a C++/Win32 project.

Hi all

I would like to write a little C# bit of code that is able to trigger the playing of short audio files from a trigger generated from say a microphone. Heres the setup - a Snare Drum has a microphone on it. You hit the snare, which pumps that sound into the mic input on a laptop. The software needs to read the mic input audio, and generate a "trigger" to play an MP3 or Wav file each time. It would be nice, but not mandatory, if the the strength of the snare hit could affect the volume of the triggered sound. Sort of a poor-mans sampler. Can anyone suggest how this could be done ? Any help appreciated...

Set up an wave input device using the managed[^] version of DirectSound. Record the input and perform a root mean square[^] on the buffers. When the intensity of the RMS reaches a certain point, trigger your sample. Use the RMS intensity to affect the loudness of the sample.

Thanks Leslie for the pointer

I dont suppose you could point me to some sample code as well ?

I'm finding it difficult to locate...

Here are a couple of Code Project articles covering Managed DirectSound:

Sound Experiments in Managed DirectX[^]

The ultimate Managed DirectSound 9 Tutorial. Part 1: a full introduction to Playback
[^]

I think these articles will get you on the right track.

I'm currently writing a synth toolkit in C# which relies on Managed DirectSound, so I've been becoming more and more familiar with it, though mainly on wave output and not so much on input, at least not yet.

At any rate, if you have any questions, let me know.

Unable to load DLL

i get

System.DllNotFoundException: Unable to load DLL 'touchlib.dll': The specified mo
dule could not be found. (Exception from HRESULT: 0x8007007E)
--at TouchlibInterop.Interop.init()
--at TouchlibInterop.Interop.initialize() in C:\Documents and Settings\donovan\
My Documents\Visual Studio 2005\Projects\TouchlibInterop\TouchlibInterop\TouchlibInt
erop.cs:line 54

even though the dll (touchlib.dll) is in the bin directory of the application i'm trying to run, and in the bin of the dll that's calling it. i've added a reference to the dll(touchlib.dll) in the dll that calls it(touchlibinterop.dll) and in the program that calls the dll. (consoleapptest)

am i missing something? i'm using DLLImport to call a unmanaged c++ method from a C# DLL, and then from the console app i'm calling a method in the C# dll that calls the unmanaged Dll.

thanks, donovan

It's not a COM dll ? If it is, it still needs to be registered.

no not the touchlib.dll , that's a unmanaged dll that a COM dll is trying to access. when i type 'regasm touchlib.dll' it tells me that touchlib.dll or one of it's dependencies couldn't be found, could it be a dependency? or am i missing something when i compile? maybe you can tell me what compile options MUST be set to get DLLImport to work with it?

could i not be exporting symbols?

None.

It sounds like your dll is missing a dependancy, if the dll is there. It's unmanaged, does it need MSVCRT, or the MFC dll ?
