For all, this is a question on the best/most elegant way to do this.
I am reading records from a database. I start the read with a database reader.ExecuteReader() method. Then I put a while Reader.read() statement to start the loop. While within this loop, I have to add up figures for certain records (store numbers). For this I use another while loop (while store number == store number). Within this while loop, I advance the records read with another reader.read() method.
The problem with this is that when it reaches the last record, the test for store number is not valid because the next record is null.
I called over my colleague to help me out with this problem, and he suggested a break on an if (!dbreader.read()). I thought this was a dirty way to get our of this, but it works!
I know I have not supplied code, but I hope you all can see it the way I explained it (this code is on a virtual machine that I do not have remote access to at the moment), But if needed I will provide.
The end question is, is it ok to use break? How often is it really used? I have always been taught not to use break/goto/gosub in C# and I just thought I would get some input here.
Thanx in advance!

the usual skeleton is:
using (SqlDataReader dbreader = reader.ExecuteReader())
{
// all your code here
while (dbreader.Read())
{
// use break wherever you want
}
} // at this point, dbreader will be disposed properly
Best regards,
Jaime.

BTW, you have a repeated question, maybe you can delete it.

Thanx for the answer....I didn't repost, but I see it.
When I try to access ir I receive this error:
XML Parsing Error: not well-formed

I was wondering if their are some apis i can call for zooming in on the desktop like the windows 7 program called Magnifier does?
|
|
|
|
|
As far as I know, Magnifier is an old tool. At least it is present since Windows XP.
Programs -> Accessories -> Accesibility -> Magnifier
Best regards,
Jaime.

Hello, i want to use the webbrowser control without hosting it in a Form how can i do that (if it's possible). I need to do that because i need to parse the generated html document and be able to work with javascript . Any help will be appreciated , thanks.

AFAIK you can have a WebBrowser navigate without being visible anywhere, and then you can access the document using the DocumentText property. Alternatively, you could forego the WebBrowser and just use HttpRequest/HttpResponse classes.

Yes , true , but no events are fired and .Document property is always null. that means that the webbrwoser needs to be run in some other way that i don't know.
|
|
|
|
|
so you are doing something wrong.
You do know Navigate() is an asynchronous call, the document is available only after the DocumentCompleted event has fired?

What is stopping you from using WebBrowser control without dragging it onto a form ?
You can always do something like:
void DoStuff() {
WebBrowser wb = new WebBrowser();
wb.Navigate(".......");
}
|
|
|
|
|
well , it doesn't work this way because the method Navigate is asynchronous and i need to have events fired like DocumentCompleted and others. I noticed that no events are fired when i don't host the WebBrowser control in a form .
|

It is because you have not subscribed to those events. Declare the WebBrowser control at the class level and subscribe to its events.
class MyClass {
WebBrowser webBrowser1 = new WebBrowser();
MyClass() {
webBrowser1.DocumentCompleted += EventHandler(...);
}
}

You also need to realize that a Form is nothing but a class (System.Windows.Forms.Form). When you put your control on a Form, the VS designer writes so much boilerplate code for you. When you don't use a form to host your controls, you need to write that code yourself.
The easiest way to learn is to put your control on a form, set its properties, create event handlers and investigate the code it creates for you. Specifically look at the designer generated code in the Form1.designer.cs (or so) file.

What II have is a small server that I been playing a round with. It's just that I can connect to it and that's about it. I been trying to do is get it so I can log and go to a menu and well doesn't look like I can get my answer from some of the other places.
So I thought I would try here. Can some one please help me set this up.
the code is below.
<br />
<br />
static void Main(string[] args)<br />
{<br />
int recv;<br />
byte[] data = new byte[1024];<br />
IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 1605);<br />
<br />
Socket newsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);<br />
<br />
newsock.Bind(ipep);<br />
newsock.Listen(10);<br />
Console.WriteLine("Waiting for a client...");<br />
Socket client = newsock.Accept();<br />
IPEndPoint clientep = (IPEndPoint)client.RemoteEndPoint;<br />
Console.WriteLine("Connected with {0} at port {1}", clientep.Address, clientep.Port);<br />
<br />
<br />
string welcome = "Welcome to my TCP server (© 2008)";<br />
data = Encoding.ASCII.GetBytes(welcome);<br />
client.Send(data, data.Length, SocketFlags.None);<br />
<br />
<br />
<br />
do<br />
{<br />
string menu = "L)ogin Q)uit V)iew Log";<br />
data = Encoding.ASCII.GetBytes(menu);<br />
client.Send(data, data.Length, SocketFlags.None);<br />
<br />
string choice = "Command : ";<br />
data = Encoding.ASCII.GetBytes(choice);<br />
client.Send(data, data.Length, SocketFlags.None);<br />
<br />
switch (choice.ToUpper())<br />
{<br />
case "Q":<br />
<br />
break;<br />
case "L":<br />
Login();<br />
break;<br />
case "V":<br />
break;<br />
<br />
default:<br />
string NotThere = "Wrong Choice";<br />
data = Encoding.ASCII.GetBytes(NotThere);<br />
client.Send(data, data.Length, SocketFlags.None);<br />
break;<br />
<br />
}<br />
<br />
} while (choice != "Q");<br />
<br />
<br />
<br />
while (true)<br />
{<br />
data = new byte[1024];<br />
recv = client.Receive(data);<br />
if (recv == 0)<br />
break;<br />
<br />
Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));<br />
client.Send(data, recv, SocketFlags.None);<br />
}<br />
Console.WriteLine("Disconnected from {0}", clientep.Address);<br />
client.Close();<br />
newsock.Close();<br />
}<br />
<br />
public static void MainMenu()<br />
{<br />
<br />
}<br />
<br />
public static void Login()<br />
{<br />
<br />
}<br />
<br />
}<br />

Would you please rephrase this, what are you trying to do?
|
|
|
|

What I want to do. Is log in and have a menu with choices. The only thing I could do with this server is connect and thats it.
I wanted en option that when I connected to the server. I could log in and it would take me to a menu. Then I could do some thing or log off.
Sorry I been up late nights so my typing may not be all that great.

Your menu would have to be on your client and then your client would forward the command to your server.
|
|
|
|
|
Ok, so would you need my client source code to show me how to do that or what do you need.
|
|
|
|
|
No, I've already told you what to do.
Try it and let me know where you have problems.
|
|
|
|
|
LOL. Right. If I new how to do that I wouldn't have posted a message asking for help.

Hi all,
I'm trying to display the tooltip by calling "ToolTip.Show(String, IWin32Window, Point)", but I wanted to do it like what Windows explorer does - displays the tooltip at the lower left corner of the cursor.
I could get the mouse position by "MousePosition", but how could I get its lower left corner position?
Thanks,
|
|

|

You'd have to get the current cursor icon and work out where inside it is the point that corresponds to the mouse 'position'.
