I have created a C sharp project in which i have added a ShockwaveFlashObject to play my swf file.
The problem i am facing is when i create an installer for my project it works correctly on my machine on installation, but on my laptop the swf loads correctly but doesn't respond to the _FSCommand. I cannot use a try and catch block as it is not entering the FSCommand handle. Do i need to bundle something with my installation?
The laptop i am using is brand new and i wanted it that way so that i know what all stuff is needed for things to work correctly so that i can add prerequisites to my installer.
Also idk if this information is of any use but I am using advanced installer to build and exe for my project.
PS i have added things like the below code to know if FSCommand gets executed.
MessageBox.Show("step 1/2/3");
Here is the entire code.

Is flash player ActiveX control installed on your laptop? You have to install it, otherwise there's nothing that can play your .swf file.

Hello I was writing a basic text editor in C# on visual studio windows form using the .NET framework 3.1 long term support version everything worked fine until I wrote the save file script

Does anyone have a suggestion about what to do I looked around on google for a solution but it seemed most did not work and some others I did not understand.

For some reason after my SaveFileDialog, my app will never show the MessageBox. Is there something I'm missing? Or is this a threading issue?
I run the application as a Windows Form application using VS 2010 Express.
I do not get any exceptions.
To add: When I step through the code, all seems to go well. Which is weird, so I believe it is a timing issue.
Pointed out by LarsTech and others, the MessageBoxes do show up, however the focus is gone; in other words the MessageBox is pushed behind other windows or minimized. This is a problem.

I tried this one and it showed right away:
MessageBox.Show(new Form() { WindowState = FormWindowState.Maximized, TopMost = true }, "You clicked Cancel button", "Cancel");
Try this for your Message Box.
MessageBox.Show(this,"Probably removed the original file.");
I created a new project and pasted your code and it works for me. Make sure you have done a full rebuild before running. Also, with this line:
dialog.FileName = DateTime.Now.ToString(format) + "." + ext;
The dialog box will have a file name to begin with. Therefore, only hitting the cancel button (assuming you don't clear the save dialog first) will trigger the message box. Either way, I got the message box to pop up by failing your IF test either way. Your code looks alright.
Perhaps you should put the SaveFileDialog in a using to ensure its disposal prior to the MessageBox call:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Globalization;
using System.IO;
namespace SpeedDating
{
class Program

{
string filename = "test.test"; // args[0];
string ext = filename.Substring(filename.LastIndexOf('.'));
using (SaveFileDialog dialog = new SaveFileDialog())
{
dialog.Title = "SpeedDating App by K.Toet";
dialog.RestoreDirectory = true;
dialog.CheckFileExists = false;
dialog.CheckPathExists = false;
dialog.FileName = DateTime.Now.ToString("yyyyMMdd") + ext;
DialogResult result = dialog.ShowDialog();
if (result == DialogResult.OK && dialog.FileName != "")
{
try
{
FileStream outfs = File.Create(dialog.FileName);
FileStream infs = File.Open(filename, FileMode.Open);
infs.CopyTo(outfs);
infs.Close();
outfs.Close();
}
catch (NotSupportedException ex)
{
MessageBox.Show("Probably removed the original file.");
}

{

I have an mobile application (.NET CF2 for Windows Mobile 6.1) that starts right after the system startup.
I want to force the form to load and them call a web service. there`s also a button that invokes the WS mannually.
I haven`t managed to first load the form so far. First it invokes the service and them it shows the form up.
Can you help me?

Just delay the processing with a timer or thread. Something along these lines:
public frmInicio()
{
InitializeComponent();
Program.ShowHide.ShowTopStatusbar(false);
ThreadPool.QueueUserWorkItem(delegate
{
Thread.Sleep(1000); // or however long you need
btnZip_Click(this, EventArgs.Empty);
});
}
Or put the call in OnActivate, checking for a first run.
EDIT 1
You have a lot (too much IMO) going on in your constructors. I'm betting the Form visibility issue has a lot to do with the fact that you are creating a Process in your Form constructor and then waiting for that process to complete before continuing. If that app is waiting on the output of your web service call, the thread creation was pointless because you've still made the constructor serially dependent on the call.
I am trying to create a recorder from audio coming out from soundcard and this is my progress so far, the problem is the recorded audio when saving to file is so large like a song can reach up to hundreds of megabyte.
here's my code
using NAudio.CoreAudioApi;
using NAudio.Wave;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Record_From_Soundcard
{
public partial class frmMain : Form
{
private WaveFileWriter writer;
private WasapiLoopbackCapture waveInSel;
public frmMain()
{
InitializeComponent();
}
private void frmMain_Load(object sender, EventArgs e)
{
MMDeviceEnumerator deviceEnum = new MMDeviceEnumerator();
MMDeviceCollection deviceCol = deviceEnum.EnumerateAudioEndPoints(DataFlow.Render, DeviceState.Active);
cboAudioDrivers.DataSource = deviceCol.ToList();
}
private void btnStopRecord_Click(object sender, EventArgs e)
{
waveInSel.StopRecording();
writer.Close();
}
private void btnStartRecord_Click(object sender, EventArgs e)
{
using (SaveFileDialog _sfd = new SaveFileDialog())
{
_sfd.Filter = "Mp3 File (*.mp3)|*.mp3";
if (_sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
MMDevice _device = (MMDevice)cboAudioDrivers.SelectedItem;
waveInSel = new WasapiLoopbackCapture(_device);
writer = new WaveFileWriter(_sfd.FileName, waveInSel.WaveFormat);
waveInSel.DataAvailable += (n, m) =>
{
writer.Write(m.Buffer, 0, m.BytesRecorded);
};
waveInSel.StartRecording();
}
}
}
}
}
can anyone help me on how to compress audio upon saving?
maybe it will be added on this part
waveInSel.DataAvailable += (n, m) =>
{
writer.Write(m.Buffer, 0, m.BytesRecorded);
};
Thanks in advance.. ;)
Try this using naudio dll
Using NAudio.Wave; Using NAudio.Wave.SampleProviders;Using NAudio.Lame
Private void WaveToMP3(int bitRate = 128){
String waveFileName = Application.StartupPath + #"\Temporal\mix.wav";
String mp3FileName = Application.StartupPath + #"\Grabaciones\ " + Strings.Format(DateTime.Now, "dd-MM-yyyy.HH.mm.ss") + ".mp3";
Using (var reader = New AudioFileReader(waveFileName))
{
Using (var writer = New LameMP3FileWriter(mp3FileName, reader.WaveFormat, bitRate))
{
reader.CopyTo(writer);
}
reader.Close();
}
}
You can't make an MP3 file by saving a WAV file with a .MP3 extension (which is what you are doing here). You will need to select an encoder available on your machine, and pass the audio through that. I go into some detail about how to do this with NAudio in this article.
