streamwriter and stream use a buffer. they don't write immediately to the file.
flush forces the stream(-writer) to write down the buffer.
alternatively you can set the autoflush flag of the streamwriter to true. the streamwriter writes the data then immediatly to the file without buffering it first.

i'm not quite sure what you mean, but maybe my first post was a bit cofusing.
the Flush Method is an Instance-Method of Streamwriter, so StreamWriter.Flush will get you a compiler Error.
You must call Flush on your StreamWriter - Instance:
wr.Flush();

namespace WindowsApplication1 {<br />
public partial class Sender : Form {<br />
Reciever reciever;<br />
public Sender() {<br />
InitializeComponent();<br />
<br />
reciever = new Reciever();<br />
reciever.Show();<br />
}<br />
<br />
private void button1_Click( object sender, EventArgs e ) {<br />

Hi,
I'm writing a mobile application and I have to use over-sized fonts and buttons so the user can use the touch-screen with fingers rather than stylus. When an error occurs I display a standard MessageBox which works fine but the button to close it is tiny and is placed on the title bar of the MessageBox.
Is there any way of increasing the MessageBox font, or placing a large button on the MessageBox?
Thanks

I don't think so, but you could easily create your own form to display errors and call that instead of MessageBox.
Another trick I've seen used is not to bother with MessageBoxes at all and to have some kind of status pane/symbol/widget in your application to highlight errors.

I used WebBrowser to get an html Document, in which there was a "Submit" button. I can get this HtmlElement. How to emulate a click in a program?
Call the elem's Click is invalid, cause it's a delegate , it can only appear in the leftside of a + or +=.
Thanks.
|

|
|
Have you considered calling the method that handles the Click event?
I will use Google before asking dumb questions
|
|
|
|
|
It's an "event delegate", you cannot call it in your code. You can only use it at the left side of + or += operator.
You know, I download an html document, it's written by other people. In the page there was a button. I want to emulate a "click" of the button in my program.
I googled but no useful result.

is it possible to return a bool on the Dictionary.ContainsKey where the key is a regex pattern?
for example if i have a hashtable (or a dictionary) of regex patterns as keys, and i want to know if the string the user entered matches to the key, do i have to search key by key with a "foreach" or does any one know a solution for searching faster.
Thanks.

Instead of wasting time on typing so much. You could have tried it with some regex example. That would have taken less time.
Anyways it is possible

"Anyways it is possible"
How is that possible
Dictionary<string, string> dic = new Dictionary<string, string>();
dic.Add(@"^L(\w{1})$", "0");
Why does dic.ContainsKey("LA") return false when it matches regex?
|
|
|
|
|
First thing I think the interpretation is wrong.
You are not using a Regex as a key of the dictionary.
Its a string object.
Then how can you search the contains key on regex?

You have to iterate over the dictionary I'm afraid. You are trying to shoehorn functionality into an item that is only a key, and has no purpose other than to identify a particular item in the collection for quick retrieval.
|
|
|
|
|
The biggest problem with that is that the value passed in may match more than one key's pattern even though the patterns are unique. You'll need to decide what to do in those cases. Iteration will be required.

hi guys
what is this operator " {0} "?
such as:
Console.WriteLine("Property Value: {0}", ///);

saeed470 wrote: what is this operator " {0} "?
This can be replaced by the object specified.
string str = "test";
int a = 10;
Console.WriteLine("{0}{1}",str,a) If you are using this, you can avoid casting the object to string explicitly.

Hi,
I was doing some experiments with C# 3.5 and I got the following code which is very tough to digest for me. Could anyone help me to understand this ?
class MySimpleClass
{
private string _Property1 = string.Empty;
private string _Property2 = string.Empty;
public string Property1
{
get { return _Property1; }
set { _Property1 = value; }
}
public string Property2
{
get { return _Property2; }
set { _Property2 = value; }
}
}Following is the code where above class instance are kept in a List<>
List<MySimpleClass> objList = new List<MySimpleClass>{
new MySimpleClass{Property1="Hello",Property2="Hello1"}
}; How such type of invoking is possible ? I checked with the overloaded constructors for List class. But I couldn't find any matching methods there. I tried removing the instance creating of MySimpleclass. Then it shows error no overload method matches the parameter. From this I guess when we specify in the above format, automatically it is calling the Add() method specified in the List. How this happening, since no overloaded constructor takes MySimpleclass as parameter ?
Any ideas ?
