I agree with this answer.
I am *SUPER* anal about my code formatting. I mean, really, super duper anal. So I thought FxCop would be my new BFF. Sadly no. I found most of its demands to be too pretentious for my tastes and quickly uninstalled it.

Hi. I want to change the function of each keyboard key.I want my application to listen to key press events globally and change key value. for example when i press 'A' while writing in notepad, my Application should see the key press event before Notepad and send Letter B to the active application. I've managed to listen the key press event globally, what i want is to block other applications from getting key press events?

Which one of the suggestions in response to your earlier question[^] did you try?
At what point did you get stuck?
What code caused which error message?

Hi,
I've been searching for days for a way to find the exchange mailstore on any exchange server given only it's name.
For e.g I have an exchange server EXSRV01, I have nothing to tell me if it is running exchange 2000,2003, 2007 etc. All I need to find is the size of the mailstore.
I was thinking I could just get the edb (and slv if it exists) file sizes, but then I don't know where they are stored because it could be stored in it's default location, or on a specific partition etc.
Is there a 'using' directive that would give me access to anything that will help?
If not, am I on a goose chase?
Thank you for any help

I have the following class:
public class WebServer
{
private readonly TcpListener _listener;
private readonly Thread _listenerThread;
public WebServer()
{
_listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 80);
_listenerThread = new Thread(ListenForClients);
}
public void StartListening()
{
_listenerThread.Start();
}
private void ListenForClients()
{
_listener.Start();
while (true)
{
TcpClient client = _listener.AcceptTcpClient();
var clientThread = new Thread(HandleClient);
clientThread.Start(client);
}
_listener.Stop();
}
private void HandleClient(object client)
{
var tcpClient = client as TcpClient;
var clientStream = tcpClient.GetStream();
var encoder = new ASCIIEncoding();
var message = new byte[4096];
while (true)
{
int bytesRead = 0;
string fileToGrab;
try
{
bytesRead = clientStream.Read(message, 0, 4096);
string msg = encoder.GetString(message);
Console.WriteLine("Client {0} connected", tcpClient.Client.LocalEndPoint);
Console.WriteLine(msg);
string[] parts = msg.Split(' ');
fileToGrab = parts[1];
}
catch
{
break;
}
if (bytesRead != 0)
{
if (fileToGrab == "/") fileToGrab = @"/index.html";
else if (!File.Exists(Environment.CurrentDirectory + fileToGrab))
{
fileToGrab = @"/error.html";
}
byte[] buffer = File.ReadAllBytes(Environment.CurrentDirectory + fileToGrab);
clientStream.Write(buffer, 0, buffer.Length);
clientStream.Flush();
string serverIp = "From server " + _listener.LocalEndpoint;
clientStream.Write(encoder.GetBytes(serverIp), 0, serverIp.Length);
clientStream.Flush();
break;
}
}
Console.WriteLine("Client {0} closed",tcpClient.Client.LocalEndPoint);
tcpClient.Close();
}
}
That is used to host a small web-server for the browser to connect to and receive data.
It works fine in a console application:
static void Main()
{
WebServer server = new WebServer();
server.StartListening();
}
But in a windows forms app:
public partial class Form1 : Form
{
private readonly WebServer _server;
public Form1(WebServer server)
{
_server = server;
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
_server.StartListening();
}
}
...When the button is pressed to turn it on, when connecting it only receives the client data, but the client does not receive the server data.
I dont know why, something to do with "[STAThread]" ?
Thanks

There's a simple way to test that: put [STAThread] on your console app. However, I'm fairly sure I've served TCP from within a WinForms app without problems in the past.
I don't immediately see the problem.
You should put some logging in the socket error catch block, as well as breaking out of the loop.
Actually never mind that, you should use the asynchronous socket methods (BeginReceive and BeginAccept), instead of creating a thread for each client. (Also, your accept thread will never terminate.) Take a look at my Sockets library[^] for an example if the MSDN docs don't make it clear enough (specifically the ClientInfo class which uses asynchronous receive, and the Server class which uses asynchronous accept).

Dear members,
I'm in search for a Visual Studio 2010 Photo Gallery website or project I can customize to my needs. It does not need to be free. I would be most grateful for any links/hints/etc leading to sites offering such contents.
My C# knowledge is limited.
thnx

It depends on the features you want but this could be very easy to build yourself. Do you want to use ASP.NET, MVC, HTML5, Silverlight?

i have project that need to reference a mathlab dll, but this dll is wroking only on 64 bit systems, because i build the dll in my 64 bit pc, when i try to run this project in 32 bit pc i get an error, but when i run the project with the dll which is built in 32 pc it works fine. so my problem is how can i add the reference at run time depending on the system(32/64), so then i don't want to keep two separate projects.
and is there any way that i can add the reference that can be selected at runtime, but the doubt i'm having is i need a reference (one of them 32 dll or 64 dll) to build the project.
appreciate your ideas.
thanx in advance.

Assuming you have two native code DLLs, one with 32-bit code, the other 64-bit code, there are basically two ways AFAIK:
1.
force your app to always run in 32-bit mode using shortcut properties. Or build your managed app for "x86"; it will always require the 32-bit DLL.
2.
build your managed app for "Any CPU". It will get launched as 64-bit whenever possible, and then it will need all-64-bit DLLs. As you normally don't explicitly load native DLLs from managed code, the best way to cope would be to have two prototypes and a stub for every native method, like so (note different DLL names!):
static class mathlabStub {
private static bool use64bit;
[DllImport("mathlab32.dll", EntryPoint=someFunction)] public static extern int someFunction32(...);
[DllImport("mathlab64.dll", EntryPoint=someFunction)] public static extern int someFunction64(...);
public static int someFunction(...) {
if (use64bit) return someFunction64(...);
return someFunction32(...);
}
and then you have to set use64bit once, maybe like so: use64bit=sizeof(IntPtr)==8;
use64bit=Marshal.SizeOf(typeof(IntPtr))==8;

I am using C# 2010 and I have an access database that connects to my form and I have 7 tables in it, all tables have the same fields but show different information (its an front end user application that connects to a database that has information on shellfish and each table is a different family but contains same field headings such as common name, size of shell, shape of shell, distribution etc...).
What I would like to is have two list boxes on my form, one to choose the table and second to choose information on the first column of the table as the first column is the common name of the species you are looking for, which is different depending on the table chosen, and when you choose one, it loads the information into the correct textboxes. How would I do this? Haven't worked with creating front end database applications for about 4 years and getting a little rusty. Thanks in advance.
In the end we're all just the same

You can still do it the same way you did it 4 years ago using ADO.NET.
If this is not legacy data, by that I mean you can change the structure without breaking other applications, merging this data into one table will make life a lot easier. Create a Family table with Id and Name fields. Then create another table called Shellfish with all the same fields and include a FamilyId field. Then insert the records from the other tables. You can do this by creating queries in Access. The reason I suggest this is because it will make developing your UI a lot easier. Normalising the data schema will make a huge difference.
Also is there any requirement for the data to be stored in Access? Access has an upgrade wizard which will make it easy to convert to a SQL Express database. This will enable you to use Entity Framework which will make development quicker if you don't include the learning curve.
Once you have done that, filling your ComboBoxes, ListBoxes, TextBoxes etc., will be a piece of cake.
If it is a legacy system you are probably resigned to cutting a lot of code in your Data Access Layer to replicate what I have mentioned above using ADO.NET.
FamilyListBox.DataSource = myData.GetFamilies();
...
private void FamilyListBox_SelectedValueChanged(object sender, EventArgs e)
{
CommonNameListBox.DataSource = MyData.GetShellFish();
}
private void CommonNameListBox_SelectedValueChanged(object sender, EventArgs e)
{
ShellFish shellFish = CommonNameListBox.SelectedItem as ShellFish;
CommonNameTextBox.Text = shellFish.CommonName;
...
}
You will also need to set the DisplayName property for the ListBoxes.
Hope that helps but it is a hard question to answer in a few words.

I have a progress bar on my first form (first form you see when application loads). What I want to happen is when the form opens for the progress bar to go up 10 every second until it gets to its maximum value of 100, stop and stay at maximum value then enable a button which is disabled.
Code on form load:
Timer time1 = new Timer();
time1.Interval = 10;
time1.Tick += new EventHandler(timer1_Tick);
time1.Start();
Code on timer tick:
progressBar1.Value += 1;
timer1.Stop();
Now the problem with this code, I get an error because the progress bar tries to go 1 higher than its maximum value and I can't figure how to get the progress bar to stop trying to go higher when its at its maximum value. I am not sure where to put the button enable code since there is something I am doing wrong here.
Next I have another button that when clicked I want it to close the form and open another form. I don't want the form to hide when closed but exit the form completly, but putting form1.close (); it won't work as its my first form, the whole app just exits. What should I do?
In the end we're all just the same

Dave McCool wrote: time1.Interval = 10;
that is 10 milliseconds.
Dave McCool wrote: progressBar1.Value += 1;
timer1.Stop();
so it will increment once, then the timer stops?
You need some conditional code. Maybe test whether incrementing the progress bar would overflow, and if so stop the timer and change the button state.

Hi,
10 milliseconds, yes that's what I meant, I wanted the progress bar to go up 1 every 10 milliseconds until it hit the maximum value then stop, btu the timer stop isn't working. The timer doesn't appear to stop, or I think the way I have the code, its won't stop as it trying to go one higher than the maximum value of the progress bar and not stopping when it gets to maximum value. I just was not sure where to put the timer stop code so that the timer would stop when progress bar gets to its maximum value, I think this way it will stop when it gets one over its maximum value, which it can't do.
In the end we're all just the same

Hello,
In a combobox when it's dropped down you can let the list scroll down by moving the mouse below the combo box. The problem is that this moves much too fast when the combo box is populated by a large number of items.
Is there a way to slow this scrolling ?
TIA
Rob

There is no property or method to do slow down the scrolling.
How many is "a large number of items"?? Putting a large number of items into a Combo is not a good idea. It makes finding items difficult for the user. Try limiting the number of items with filtering first.
|
|
|
|

Pity there's no way to slow down the scrolling, but thanks for your answer anyway, I don't have to search for the needle in the haystack anymore.
A large number of items is a couple of hundred, eg the items for sale in a company. I have created a filtering option but the user wants to see the total list at once.
Thanks for your time.
Rob
