I have written a small debug class so I can echo some statements to the ouput in VS and to a text file, using the StreamWriter class... The problem is, is that the text is never written to the file.
<br />
public class Debug<br />
{<br />
private StreamWriter _writer;<br />
private string path;<br />
<br />
public Debug(string path)<br />
{<br />
this.path = path;<br />
if( File.Exists(path) )<br />
_writer = File.AppendText(path)<br />
else<br />
_writer = File.Create(path);<br />
}<br />
<br />
public void WriteLine(string output)<br />
{<br />
string s = DateTime.Now + "\t" + output;<br />
<br />
System.Diagnostics.Debug.WriteLine(s);<br />
_writer.WriteLine(s);<br />
}<br />
}<br />
Now this is fairly bog standard code foe writing to a file, and even stranger is if i replace the WriteLine procedure with
<br />
public void WriteLine(string output)<br />
{<br />
string s = DateTime.Now + "\t" + output;<br />
System.Diagnostics.Debug.WriteLine(s);<br />
StreamWriter sw = File.AppendText(this.path);<br />
sw.WriteLine(s);<br />
sw.Close();<br />
}<br />
The text is written to the file fine. Can any shed light on this.... What dumbass thing I am I doing wrong?

Could it be because you are not explictly closing the stream in your original and maybe it is not being flushed?
Personally, in my logging I do not try keep the file open all the time, I use:
public void Write(string message, LoggingLevel level)
{
StreamWriter logFile=null;
lock(this)
{
try
{
logFile = new StreamWriter(fileName, true);
logFile.WriteLine(message);
logFile.Close();
}
catch(Exception)
{
if(logFile!=null)
logFile.Close();
}
}
if(isSystemDebugEnabled)
System.Diagnostics.Debug.WriteLine(s);
}

I'm trying to detect which cursor is currently shown on the screen, whether it is a wait cursor, arrow cursor, etc. Right now, the detection works perfectly EXCEPT that there are 3 cursors that i can't seem to detect sometimes - the hand cursor, horizontal and vertical splitter cursors.
The code i'm using is (with the GetCursorInfo API):
Info.Size = Marshal.SizeOf(Info.GetType());
GetCursorInfo(out Info);
if (Info.Cursor == Cursors.WaitCursor.Handle)
CurrentCursor = "Wait";
else if (Info.Cursor == Cursors.Default.Handle)
CurrentCursor = "Default";
else if (Info.Cursor == Cursors.AppStarting.Handle)
CurrentCursor = "Loading";
else if (Info.Cursor == Cursors.Hand.Handle)
CurrentCursor = "Hand";
....
After i did some tests, i noticed that when i convert the values to string, the two values of Info.Cursor and Cursors.Hand.Handle (along with the HSplit and VSplit values as well) do not tally and they tend to change over and over again almost every time i run my application again.
The tests were done by displaying the values of Info.Cursor and Cursors.Hand.Handle using codes like these:
MessageBox.Show(Info.Cursor.ToString());
MessageBox.Show(Cursors.Hand.Handle.ToString());
I did the tests mostly on Applications that have a weblink and also on web browsers. When using a web browser, the detection seems fine (for the hand cursor at least) but when i run an app that has a weblink somewhere and the hand cursor shows up, the values of Info.Cursor and Cursors.Hand.Handle are totally different.
Is there a way around this?

try using the .NET way, Cursor.Current

Cursor.Current only detects the cursor within the form. I need to detect the cursor system-wide (i.e: both inside and outside the form).

Hi! I have the following code:
Stream stream = new FileStream("Form1.resx", FileMode.Open);
And the default directory for Form1 is in WindowsApplication1\Bin\Debug right?
But I want to use the resx in the WindowsApplication folder. How do I do this?
Please help this newbie.

Form's .resx file is an embedded resource. This means you can access it as shown below:
Assembly assembly = Assembly.GetEntryAssembly();
Stream stream = assembly.GetManifestResourceStream(
"WindowsApplication1.Form1.resx");

Whichever you find appropriate. Just don't forget to update the parameter of GetManifestResourceStream() to "Namespace.Of.Form1.resx".

Hi! I used the follwing code:
Assembly assembly = Assembly.GetEntryAssembly();
Stream stream = assembly.GetManifestResourceStream("WindowsApplication7.Form1.resx");
ResourceReader a = new ResourceReader(stream);
IDictionaryEnumerator en = a.GetEnumerator();
en.MoveNext();
MessageBox.Show(en.Key.ToString());
MessageBox.Show(en.Value.ToString());
a.Close();
But I get an exception stating that:
An unhandled exception of type 'System.ArgumentNullException' occurred in mscorlib.dll
Additional information: Value cannot be null.
Why is this?

I probably misunderstood your question. You will need: System.Reflection and System.IO.

Replace WindowsApplication7.Form1.resx with WindowsApplication7.Form1.resources. This should work.

When I go to 'About' in Visual Studio it says I have 1.0.3750...
I have the 1.1 installed on my computer... How do I get visual studio to use it?

You install VS.NET 2003.
VS.NET is tied to the version of the framework it shipped with, VS.NET 2003 is the same way but it has an added feature to generate a .config file so your application can use version 1.0 at runtime.

Just to check a few things:
Do you have a "myapplication.exe.manifest" file in your application's directory? Or have you followed one of the article's here on CodeProject where you embed the manifest, and have you remembered to redo the embedding each time you rebuild your application?
For the controls that support it, do you have the FlatStyle property set to "System"?

If your application is called blah.exe, create a manifest file:
blah.exe.manifest
in the directory in which your executable is located. Check MSDN for the manifest file layout. In there, modify the required version to the version of the runtime you want to use.
