Or......
At startup allocate one receive buffer that will accomodate that largest message you expect (plus a little overhead is OK too). Then on your message received function, New a temp buffer of the exact size of the received message and then Array.Copy the new message into a buf, then use it however you wish.

Hello
Ok, Lets imagine we have a Table in sqlServer with these fields:
id (int) , name (nVarChar) , sex (bit)
I show you examples about UPDATE Query with Parameters :
strSQLUpdate = "UPDATE Table SET name=@name,sex=@sex WHERE idu=@idu" ;<br />
cmd = new SqlCommand(strSQLUpdate,Connection) ;<br />
cmd.Parameters.Add ("@id",SqlDbType.Int, 4,"id") ;<br />
cmd.Parameters ["@id"].Value = txtID.Text ;<br />
cmd.Parameters.Add ("@name",SqlDbType.NVarChar, 20,"name") ;<br />
cmd.Parameters ["@name"].Value = txtUsername.Text ;<br />
cmd.Parameters.Add ("@sex",SqlDbType.Bit, 1,"sex") ;<br />
cmd.Parameters ["@sex"].Value = radioButton.Value ;<br />
cmd.ExecuteNonQuery() ;
If you need more codes please alert me and wait 5 hours.

Hi!
If you want to learn how to use RegEx, just search in google. Helpful is one of the regex trainer which let you test your regex search-string before you use it.
But here is an example to catch URLs:
// Clear old data in listboxes
listBox1.Items.Clear();
listBox2.Items.Clear();
// example HTML document
string lsCode = "<HTML><BODY>test1<BR><A HREF='LinkURL1'>Link1</A><BR>test2<BR>" +
"<A HREF='LinkURL2'>Link2</A><BR></BODY></HTML>";
// Regex object to search
System.Text.RegularExpressions.Regex loCheck = null;
// search-string for regex (improtant: ignorecase-option)
loCheck = new System.Text.RegularExpressions.Regex("href=[\"']{0,1}([^\"'> ]*)", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.Text.RegularExpressions.MatchCollection loLinks = loCheck.Matches(lsCode);
// write every value in the list
foreach (System.Text.RegularExpressions.Match loResult in loLinks)
{
// loResult.Groups[0].Value = "HREF='LinkURL1"
// loResult.Groups[1].Value = "LinkURL1"
listBox1.Items.Add(loResult.Groups[1].Value.ToString());
}
// search-string for regex (improtant: ignorecase-option)
loCheck = new System.Text.RegularExpressions.Regex("[\"']>{0,1}>([^<]*)</A>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);
System.Text.RegularExpressions.MatchCollection loLinksText = loCheck.Matches(lsCode);
// write every value in the list
foreach (System.Text.RegularExpressions.Match loResult in loLinksText)
{
// loResult.Groups[0].Value = "'>Link1</A>"
// loResult.Groups[1].Value = "Link1"
listBox2.Items.Add(loResult.Groups[1].Value.ToString());
}
In listBox1, all Link addresses will be added. In listBox2, all link text (within <A HREF>???</A>) will be added.

Hallo C# Friends  ,
I've a problem and hope for help.
I've created an automation addin for excel with .Net 1.1. It works fine.
Now, the same addin should work with fw 2.0.
I created a new Project with vs2005 (Addin Project). Same settings like the old addin.
I installed the addin and want getting started. But the addin won't start. The Function OnConnect never get started.
Has anybody else the same Problem or can anybody give me help?
Thank for attention

Dear group:
I have this Marco witch I wanna run it from my C# App.
Sub Macro1()<br />
If ActiveWindow.View.SplitSpecial <> wdPaneNone Then<br />
ActiveWindow.Panes(2).Close<br />
End If<br />
If ActiveWindow.ActivePane.View.Type = wdNormalView Or ActiveWindow. _<br />
ActivePane.View.Type = wdOutlineView Then<br />
ActiveWindow.ActivePane.View.Type = wdPrintView<br />
End If<br />
ActiveWindow.ActivePane.View.SeekView = wdSeekCurrentPageHeader<br />
Selection.TypeText Text:="<big>a header here</big>"<br />
ActiveWindow.ActivePane.View.SeekView = wdSeekMainDocumentEnd Sub
This is what I did but got an error in *oWord.
oWord.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekCurrentPageHeader;<br />
*oWord.Selection.TypeText text = "<big>a header here</big>";<br />
oWord.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekMainDocument;
My goal is adding a Header with Dynamic Text.
Tnx in advance.
Always ,
Hovik Melkomian.

i'm trying to use " in a string variable but can't.
So:
string x=""";
how can i do that?
|
|
|
|
|
\ <-- is the escape char
string myString = "Hello \"World\"";
|
|
|
|
|
Escape the quote using the \ escape character:
string x = "\"";
or use a @-quoted string and double quotes:
string x = @"""";
---
b { font-weight: normal; }
|
|
|
|
|
Hi!
In C# you cannot do that in that way, this is just possible in VB. But you can use excape sequences for that:
string x = "\"";
The Backslash shows the compiler: 'the next charcater is a control character and not an normal character!'.
Her are other Escape-sequences:
\n = new line
\r = carriage return
\t = tab stop

Yes, it's possible in C#. @-quoted strings in C# works just like strings in VB:
string x = @"""";
---
b { font-weight: normal; }

Hi!
Thx! Didn't know!
Marcel Erz

i tried that
string x="\"";
if i want show it on screen,it's right.but i want search this in a richtextbox.
then it finds not " alone,it finds with "\".
|
|
|
|
|
Sure! You shoq the compiler with the "\", that it is a special character. So, even in searching, you need to input a "\". Otherwise the compiler will not know if it is a " in a string or a " around a string.
Marcel Erz

The string x will contain one single character, the quotation mark.
If you have any trouble using it, you have to be using it the wrong way. How do you use it?
---
b { font-weight: normal; }
|
|
|
|

try this
char hi= '"';
string say = "hello my name is "+ hi+ "james" + hi;
I hope this helps u
