Thanks. I had read this, but for some reason I cannot now remember, I questioned it. Seems pretty straightforward now!

You're welcome.

P.s. Really glad to hear that you thought about this instead if just asking

I think what I blew off was that SPEFICICALLY, enumeration wasn't thread safe. In my mind I thought "well, if getting things from a synchronized queue isn't thread safe, what's the point?"
My brain didn't translate the part where "Only the enumeration itself needs LOCK, the rest of the Queue methods do not."

Hi, everyone...
I have a stream and put in a GZipStream, save in SQL 2005, after that I load this stream from sql 2005 and try to deserialize from BinaryFormatter. This will be the GOLD, for now a simple serializable-Compress-Decompress-Deserializable is very fine...
But, I´m getting a error:
"Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization."
Any help?
My Code:
public static void Main()
{
List<string> p3;
List<string> p1 = new List<string>();
p1.Add("Brazil");
p1.Add("Error");
p1.Add("Serializable");
Stream Serial = new MemoryStream();
FileStream fileStream = new FileStream("Teste.bin", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
Processo _Retorno = new Processo();
BinaryFormatter teste = new BinaryFormatter();
teste.Serialize(Serial, p1);
byte[] buffer = new byte[Serial.Length];
Serial.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
fileStream.Close();
byte[] Compremido = Compressor.Compress(buffer);
byte[] Descompremido = Compressor.Decompress(Compremido);
MemoryStream msUnZip = new MemoryStream();
msUnZip.Write(Descompremido, 0, Descompremido.Length);
msUnZip.Seek(0, SeekOrigin.Begin);
BinaryFormatter Serializador = new BinaryFormatter();
p3 = (List<string>)Serializador.Deserialize(msUnZip);:mad:
}
</string></string></string></string>
public static class Compressor
{
public static byte[] Compress(byte[] data)
{
MemoryStream output = new MemoryStream();
GZipStream gzip = new GZipStream(output,
CompressionMode.Compress, true);
gzip.Write(data, 0, data.Length);
gzip.Close();
return output.ToArray();
}
public static byte[] Decompress(byte[] data)
{
MemoryStream input = new MemoryStream();
input.Write(data, 0, data.Length);
input.Position = 0;
GZipStream gzip = new GZipStream(input,
CompressionMode.Decompress, true);
MemoryStream output = new MemoryStream();
byte[] buff = new byte[64];
int read = -1;
read = gzip.Read(buff, 0, buff.Length);
while (read > 0)
{
output.Write(buff, 0, read);
read = gzip.Read(buff, 0, buff.Length);
}
gzip.Close();
return output.ToArray();
}

JUST for awnser this...
It´s necessary to put
Serial.Seek(0, SeekOrigin.Begin);
Between:
byte[] buffer = new byte[Serial.Length];
Serial.Read(buffer, 0, buffer.Length);

I have a piece of javascript code that writes to a local file. When this happens, how can I notify a running C# WinForm application so C# app can process the file.
Thanks.

You could always use a FileSystemWatcher to keep an eye on this file.

I'm trying to change the system date and time on XP Pro:
In the form's class header I have:
[DllImport("kernel32.dll", SetLastError=true)]
public static extern bool SetSystemTime( [In] ref structSystemTime st );
public struct structSystemTime
{
public short wYear;
public short wMonth;
public short wDayOfWeek;
public short wDay;
public short wHour;
public short wMinute;
public short wSecond;
public short wMilliseconds;
}
Then in Form_Load I have:
structSystemTime st = new structSystemTime ();
st.wYear = 2003;
st.wMonth = 5;
st.wDay = 22;
st.wHour = 22;
st.wMinute = 15;
st.wSecond = 08;
SetSystemTime(ref st);
It compiles and runs, but the date/time doesn't change. Anyone know what's wrong?

Change the definitions of the fields from short to ushort (unsigned short).

If fixing the structure doesn't help, does
GetLastWin32Error() return a useful error code?
if (!SetSystemTime(ref st))
{
int errcode = Marshal.GetLastWin32Error();
}

I changed the struct and it did not work. It returned 1314, which is:
if (!SetSystemTime(ref st))
{
int errcode = Marshal.GetLastWin32Error();
string errorMessage = new Win32Exception(Marshal.GetLastWin32Error()).Message;
MessageBox.Show(errorMessage);
}
Turns out the Sys Admin has restricted users from chaning the date/time.
Now to go find the sys admin....

There is usually a good reason, good luck with the Admin, take your flame proof suit!

Whenever I use WinAPI, the equivelant of any integer (short or int) in API documentation, I always have to use Int32.

I have the same problem but the marshal tells me that error 57
Have you managed to solve it?

Before you get an answer to this question, you're going to have to do some serious convincing that this is for a legitimate purpose. Why do you need to do this?

As he said earlier, why do you need this?

Hi,
How do you build a project of multiple classes and resources using the CSC program from the command line?
Many thanks!

Hi Guys,
I am wondering if it is possible to search all the computers within a domain or a network to discover all the excel files and then store them in a common location?
I have seen some examples of searching computers in a domain but didn't find any example for file search in a domain.
Can somebody help please?
Thanks
happy coding!

Why on earth would you do that instead of letting the user decide what should be commonly accessed and what shouldn't be?

I can see an admin requirement for this but I don't think you are going to achieve it. You need at least read only access to EVERY folder on the network. I imagine if you own the network you could do this, IBM has a tool to check the files on a PC but they turn up with a USB key to do it and I'm pretty bloody sure they would rather do it centrally  .
There are a number of enterprise tools out there which require you to register a sheet and it stores it in a database and uses version control and change management on the REGISTERED files only. Serious enterprise money though.
