TCP uses an explicit RST (reset) message to close a connection. The connection can also die due to a timeout.
|
|
|
|
|
Where is the timeout for the connection set?
|
|
|
|
|
socket.ReceiveTimeout and SendTimeout
|
|
|
|
|
TCP sockets are by definition reliable. UDP sockets on the other hand are not. As stated above, the browser is closing the connection explicitly.

Is there a way to export a WinGrid with more than 256 columns to a single Excel sheet.

They have Ultra-Win-Grid for that.

Is there anyway which we can convert the multi page tiff files into pdf format in C#? I googled for quite sometime. Majority of the code uses a third party s/w which will be licensed for commercial use.
Is there any free s/w that can be used in C# to convert the same? Or any open source tool for the same?
Thanks

I would suggest using [ItextSharp].
This open source on itext (java) based library, will provide you with the possibility to create a new pdf based on whatever images you want.
Example to get you started
[Itext-convert-tiff-to-PDF]
Another thing you can use is ghostscript, but I think this can just be used from the commandline...

Thank you for this.
One of my java developer friend has already examined this. Some of the files are able to convert, but some are end up with error message saying that 'Byte array not a valid JPEG file'.
One of our senior developer suggested that it may be because of JPEG-2000 issue, because of that some of the tiff files are not able to convert to PDF.
However, I am able to view all the tiff files without any issues using FastStone Image viewer,converting to PDF at one short. But this will be a licensed one for commercial purposes.
I want to know if there are any free versions or is it possible to achieve this somehow in dotnet.
Thanks in advance

Hello Everybody,
I have some problem while to pass the value of of Object.
DObject D = new DObject();
Dobject D1 = new DObject();
Private void ChageValues()
{
D = ComeFromFile();
D1 = D;
D1.Name = "Piter";
}
if i am try to change the property of D1 then D is also changing.
So How can i Sepreate to both of them.
If you can think then I Can.

You can use ICloneable interface so that it will make only copy of the object.

Try doing a deep copy or clone of D - Something like D1 = D.Clone().
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

########## Please see the modified solution below ##########
Include this method in one of your class:
public static void CopyTo(object S, object T)
{
foreach (var pS in S.GetType().GetProperties())
{
foreach (var pT in T.GetType().GetProperties())
{
if (pT.Name != pS.Name) continue;
(pT.GetSetMethod()).Invoke(T, new object[] { pS.GetGetMethod().Invoke(S, null) });
}
};
}
I hope this is helpful

Please don't.. 
As a last resort maybe, if you don't control the source of the type.

That's a code horror. You are calling GetProperties far too many times -- you probably only need to once.
|
|

|
|
Thanks sir, will keep it in mind in future

To understand this behavior, you'll need to know the difference between a value type and a reference type.
Your 'DObject' is a reference type and hence assignment results in the variable pointing to the same object instead of a new object being created as in the case of a value type.
You'll need to implement IClonable interface and implement its Clone method, and then do something like this
D1 = D.Clone();
|
|
|
|
|
In your example you don't need to initialize the objects.
|
|
|
|
|
I propose another solution, seeing problems with my previous solutions, although working.
You can write your own
Clone() function inside your class. You need to mark your class as
[Serializable]
Function can be written as:
public object Clone()
{
object oClone;
using (MemoryStream myStream = new MemoryStream())
{
BinaryFormatter binFormatter = new BinaryFormatter();
binFormatter.Serialize(myStream, this);
myStream.Position = 0;
oClone = binFormatter.Deserialize(myStream);
}
return oClone;
}
You can call this function as
eg:
Person p2 = (Person)p1.Clone();

Hi, I think this is your answer here.
Use of MemberWiseClone method of System.Object.
Please refer below example, you will come to know how to pass value of object and if you change one then other will not change like any other value type.
class Program
{
static void Main(string[] args)
{
D1 d = new D1();
d.Prop1 = "Sample...";
D1 d2 = d.ShalloCopy();
d2.Prop1 = "Some else";
}
}
class D1
{
public string Prop1 { get; set; }
public D1 ShalloCopy()
{
return (D1)this.MemberwiseClone();
}
}
In above example, when you make change into d2 then d will remain same it will not change.

I have a datagridview in a winform application, that gets data from an external dll and displays it dynamically.
As the new rows are getting added I want to show the newly added row to the user (so that the old rows keep moving upwards).
I am adding the new rows and showing the last added row as follows
string[] currentRow = new string[5];
currentRow[0] = curr.sequence().ToString();
currentRow[1] = typeString;
currentRow[2] = curr.stat().ToString();
currentRow[3] = detail;
currentRow[4] = curr.timestamp().ToString();
this.dataGridView1.Rows.Add(currentRow);
this.labelCount.Text = curr.sequence().ToString();
dataGridView1.CurrentCell = dataGridView1.Rows[curr.sequence()-1].Cells[0];
I am getting an exception of
[System.ArgumentOutOfRangeException] = {"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"}
at the line where I set the CurrentCell.
Although it occurly at random rows everytime. Sometime it occurs as early as 25th row. Other times at 1000th row.
What could be causing it? I see that the sequence is displayed correctly at labelbox.
Please help.
Thanks in advance.
