Hello,
Ok, The code file where I am using BackgroundWorker i have following using statements, you can just copy all of them for the time being for debugging purpose.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using SpeechLib;
using System.Threading;
Moreover Backgroundworker is a control available in your C# ToolBox. It is a new component in .NET 2.0 (2005 Express Editition). So, if you are using .Net 1.1 (Visual Studio 2003) then dont use this code.
"By the way could you tell me which class that the object backgroundWorkerLetterTalker belongs to ?"
:: backgroundWorkerLetterTalker was an instance variable name of BackgroundWorker Control, not any standard .net class name.
OK, If you have too much trouble about Background worker, then forget about backgroundWorker.
For simplicity, just to test Text to Speech, put this code without background worker. At least you will hear voice from machine.
private void btnSpeak_Click(object sender, EventArgs e)
{
///////////////////////////////////////////////////////////
string arg = "HEllo I am speaking";
SpVoice objSpeech = new SpVoice();
objSpeech.Speak(arg, SpeechVoiceSpeakFlags.SVSFlagsAsync);
objSpeech.WaitUntilDone(Timeout.Infinite);
///////////////////////////////////////////////////////////
}

Hi I have built a project for you and sent you email with an zip file attachment. This project is working perfectly in my PC. If it is not working in your pc, then may be your pc is not equipped with microsoft speech features or may be something else wrong. And this project is built in .NET 2.0 (C# express 2005). If you have the previous version, then just open the file form1.cs and see the code and then use in your previous version IDE.

I'm thinking of making a VoIP program because the voice convo's in MSN messenger only connect like half the time. Can anyone direct me to some good articles or give me some advice on where to start?

Those seem to be good libraries but I can't add them as a reference in my project. It says they are an invalid COM component.

An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll
"System.Data.OleDb.OleDbException: Could not find file 'D:\\AttendanceDB.mdb'.\r\n at System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr)\r\n at System.Data.OleDb.OleDbConnection.InitializeProvider()\r\n at System.Data.OleDb.OleDbConnection.Open()\r\n at System.Data.Common.DbDataAdapter.QuietOpen(IDbConnection connection, ConnectionState& originalState)\r\n at System.Data.Common.DbDataAdapter.FillFromCommand(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)\r\n at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)\r\n at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet)\r\n at SanMarCalendar.SanMar.cmbGroups_SelectedIndexChanged(Object sender, EventArgs e) in d:\\sanmar\\sanmarcalendar\\forms\\sanmar.cs:line 1338"
i never even told it to set it to that file or any other file the proper location of the file is set by default to ../../AttendanceDB.mdb but for some reason whenever i use an openfile dialog it sets it to the above. and gives me this exception why is openfile dialog changing my oledbConnection string 
|
|
|
|

Have you tried giving the connection string the entire physical path of the DB just to see if it still does it? Mabey you could try changing the path so something like:
Application.StartupPath() + "\AttendanceDB.mdb";
and see if it still gives you the error.

the connections all work fine untill i open the open file dialog then they all die once i try to use them after the open file dialog
it actualy looks like whenever i call fill on an adapter it dies after the open file dialog
the open file dialog has nothing to do with the database stuff.

This is more-than-likely because your connection string isn't specifying a complete path to your database, something like "DataSource=mydata.mdb". Since you left out the fully qualified path, it is assumed that the database is in the current directory.
The OpenFile dialog will change the current directory to whatever was picked in the dialog, thereby breaking the path to your database. ALWAYS use fully qualified paths when working with any kind of files.
string dbPath = Path.Combine(Application.StartupPath, "myData.mdb");
string connString = String.Format("blah;DataSource={0};", dbPath);

I am writing a small program to check some services in W2k3 using C#. It's kind of simple to get the services name as well as their statuses, but I don't know how to get their logon (logon as what account) and recovery information.
Anyone knows how to do that?
Thanks much,
Johnny

Hi everyone,
For a quite complicated and boring purpose, let's say a project for the university, I have to find a way to create a pointer on an array of int. It sounds easy and in C++ it would take 1 second. But in C#, I don't know how to do that. Has someone an idea?
I let you a few lines of code that does NOT compile because it tries to get a pointer from a managed type:
unsafe
{
int* ptr;
int [] array = new int[SIZE];
ptr = &array;
}
the same error appears with an array of float or of byte.
I have tried to use the 'fixed' keyword, but that didn't help neither.

|
|
|
int[] array = new int[50];
fixed (int* parray = array)
{
...
}

Hello,
Which is the accepted practice in .NET coding, to just throw everything in a single project into a single namespace, or to separate different parts of a project into different sub-namespaces?
For instance, should I put all structures into a namespace called "Project.Structures", and then put all dialogs into "Project.Dialogs", and so forth?
Thanks,
Rich

If it is a small throw away application then that would be acceptable.

Yes. And split the solution into multiple projects.

Typically I'd say a layering patter would be better (you can, of couse, split the layers in to finer grains if you want). I'd have a UI project, a business project, and a data access project. The reason for that is that it prevents circular references. Your UI project referenced the business project, and the business project references the data access project. If any other references between these projects needst to be set up then I know I'm doing something wrong.

Hi,
I create an user control, and use the following code to create it, is the code ok?
private void func(){
myctl mc=new myctl();
Panel1.Controls.add(mc); //panel1 is a panel I put in a form
mc.show();
}
it works fine, but I think mc should out of range(be destroyed automatically) once the function call end.
Or the controlcollection of the Panel control still keep it alive???
I am listening .....

It will be kept alive until there are no more references to it. Since it is referenced by panel1's Controls collection, it will be kept alive at least until it is either removed from that panel or the panel is disposed and no longer referenced.

Hi,
I hope it's just a simple question. When I unintall my .NET/C# program that I installed using my own setup programe, the program shortcut in the start menu doesn't get cleaned up completely. The content is removed but the folder remains. How can I remove the folder at uninstallation time? Thanks for help!
