Hi
I needed to find a way to determine whether or not someone has started typing on the keyboard.
I found Console.KeyAvailable and so tried to have the following code running in it's own thread:
while (true)
{
while (Console.KeyAvailable == false) { };
isTyping = true;
Console.WriteLine("Key pressed!");
}
And then another thread that is constantly performing a Console.ReadLine (to read keyboard input) would reset the isTyping flag to false after a successful ReadLine.
But it appears that Console.KeyAvailable never returns true even when I type on the keyboard or even hold a key down. Is it possibly affected by any other actions occurring on the Console or by threading?
Or does anyone know any other way to determine if someone has started typing? The scenario is I'm using the console window as a chat client and I only want to display server messages if the client hasn't started typing since they last sent a message.
Thanks
Glen

Its out the top of my head, havnt tested it, but maybe Console.In.Peek() would do it for you?
it returns -1 if no character is avaible

Hi all,
I am trying to execute the below code.
s = (char)ulong.Parse("01040209000D0006040705000D0008020208000D0006010204", System.Globalization.NumberStyles.HexNumber);
While executing the above code i am getting below error:
Value was either too large or too small for a UInt64.
Plz some one suggest me how to solve this issue.

The error says everything you want to know. Have you tried with a shorter number (shorter in number of decimal). Ulong has it's minimum value 0, of course, and it's maximum value 18446744073709551615. Your number is much much bigger than the maximum value of ulong

hi all;
what i need to do is send a pdf as atachment in mail and before that i also need to secure it with a password , what i need to do is to pass data from memory stream to pdf and then apply password to it and then reconvert it to memory stream and then pass it as attachment
following is the code if u need to check ...
thanks!
byte[] bytes = lr.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);// here im converting the report to pdf format
MemoryStream s = new MemoryStream(bytes);// this puts the report data into the memory stream
s.Seek(0, SeekOrigin.Begin);
Document doc1 = new Document();
//doc1.Open();
PdfWriter p1= PdfWriter.GetInstance(doc1, new FileStream("Chap0101.pdf", FileMode.Create));
PdfWriter.GetInstance(doc1, s);
p1.SetEncryption(PdfWriter.STRENGTH128BITS, "admin", "admin", PdfWriter.AllowPrinting);
//doc1.Close();
Attachment a = new Attachment(s,"example.pdf");
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("kuruvilla.philip@rave-tech.com", "kuruvilla.philip@rave-tech.com", "A report for you!", "Here is a report for you");
message.Attachments.Add(a);
SmtpClient client = new SmtpClient("server");
client.Send(message);

It's not...the ASP.NET forum is for web.

The script itself is written at design time, yes. You want to write the script at runtime?

This would be done entirely in Javascript on the client side. The question should be posted in the Web Development forum.

I have 2 databases and one table for each of database. The tables have the same structure. One of them is populate and I want to copy the contain of this to the second table. I want to ask if this is possible with DTS.
thx

Yes, better ask in the SQL messageboard though.
IMO you will be better off using a simple cross database INSERT/SELECT if they are running on the same instance (that said, copy/paste should work too from within VS).

Hi,
I parsed a CSV file and loaded in a dataset. All the columns got loaded in the dataset with extra empty cells. I need only the columns in the CSV file with values to be parsed and loaded in Dataset. Can any one help me out. I am using the following Code to parse
string ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Text;HDR=No;FMT=Delimited\\\"";
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection(ConStr);
System.Data.OleDb.OleDbDataAdapter da = new System.Data.OleDb.OleDbDataAdapter("Select * from " + file, conn);
da.Fill(ds, "TextFile");

Search CodeProject for an article that shows you how to do this.

My guess would be that you opened the csv file in excel and then saved the file which added a bunch of extra empty cells. I would suggest adding some code to your csv parsing program that checks for extra empty cells and excludes them.

Hi,
My problem is to create a delegate for the following callback definition (c++ syntax):
typedef void (__stdcall *UnmanagedCallback)(std::wstring& WStringObject, const wchar_t* StringData, unsigned __int32 StringLength);
I tried something like this:
public delegate void UnmanagedCallbackDelegate(ref string stringObject, string stringData, UInt32 stringLength);<br />
or:
public delegate void UnmanagedCallbackDelegate(ref string stringObject, [MarshalAs(UnmanagedType.LPWStr)]string stringData, UInt32 stringLength);
The callback fired from the dll is a _stdcall.
Someone has a clue what I do wrong?
Thanks in advance...
Uwe.

You can use the DllImportAttribute[^] to specify the CallingConvention[^], but I don't think .Net will marshal STL strings to a String.
You would probably have to specify those parameters as an IntPtr, then convert the code from this[^] article to C# (it's shown in the "Converting String to std::string" section).
Take care,
Tom

There's C# samples that do this on this site.

I have a graph created in a zedGraph control on my form.
A separate thread handles the data collecting and preparing for graph purposes.
When I hit start I can see the zedGraph control resizing alright but i cant see the curves.
If I leave the focus of the form and then return to it(say with alt_tab or the mouse)
I can see the curves.
It operates in a manner that led me to think of a refreshing problem.
can you please advise me what to do?
thank you.

That implies that your graph is only redrawn when invalidated, so call Invalidate() either on the whole form or the graph control when you know the graph is ready to be displayed.
|
|
|
|
|
I tried Invalidat() and I tried refresh(), none of which does the trick.
It seems like the axis are changing correctly and only the curves themselves don't show.
Any other ideas?
