How to translate the property item name of the control in the properties window?

18-Jan-09 23:11

Hello everyone,

I met with timeout issue. Here is my whole code. I just send Http request to two local LAN servers and see if response could be received in given time, then I treat the server as healthy, or else I will treat them as unhealthy.

The two servers are simple ASP.Net ASMX Web Serviers Web Servers on IIS. The timeout will happen for both servers are PingServers method executing for 4-5 times successfully. It is strange timeout since the server are pretty fast -- I use IE to access the same URL, it takes less than 1 second to return, but in my code, I set timeout to be 4 seconds, it will prints timeout.

Does anyone have any ideas? Any bugs in my code?

static void PingServers(Object state)
 {
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create((String)state);
     request.Timeout = 4 * 1000;
     HttpWebResponse response = null;
     try
     {
         response = (HttpWebResponse)request.GetResponse();
     }
     catch (WebException ex)
     {
         Console.WriteLine((String)state + " " + ex.ToString());
         return;
     }

     Console.WriteLine((String)state + " is healthy");

     return;
 }

 static Timer[] monitorTimers = new Timer[2];

 static void Main(string[] args)
 {
     monitorTimers[0] = new Timer(PingServers, "http://localserver1/test/test.ashx", 0, 10 * 1000);
     monitorTimers[1] = new Timer(PingServers, "http://localserver2/test/test.ashx", 0, 10 * 1000);

     Console.ReadLine();

     return;
 }

thanks in advance,
George

Donwload the .NET languagepack[^] of your choice and install it. It doesn't only translate error-messages, but also properties, if I'm not mistaken.

You cannot translate the texts by yourself, since there is no interface.

Thank Eddy for your answer.

I remember my colleague I have achieved this funtion in his program,not handling by the system languagepack,He can change the Text property of the button with any name.

The language-pack does it automatically, and the translations are embedded deep in the .NET runtime. It's a low-impact solution to your question, and I suggest you take a look at it before experimenting with sourcecode.

BTW, my Visual Studio IDE @ work uses these Dutch language-packs, and it's bloody annoying to search for something simple like "ForeColor". Not only is the sort-order different (Voorgrondkleur), but it's in a category with a different name. It gets worse when you're facing a localized version of an error - and you need to search the English-based MSDN for the same error.. It doesn't increase the productivity, it just causes more bugs.

Within the computer, everything should remain in a single language. That has nothing to do with the language that the end-user sees. It's just not possible to teach a computer all the localized versions of a boolean.

Phone your collegue, ask how he did it Smile | :)

You could also redefine the property-names, as shown in the example below;

/// <summary>
/// This is the original property. We want to 'rename' these in code as well as
/// in the property-editor. First, we'll hide the current property as much
/// as reasonable:
/// </summary>
[Browsable(false)]
public override System.Drawing.Color ForeColor
{
    get
    {
        return base.ForeColor;
    }
    set
    {
        base.ForeColor = value;
    }
}

/// <summary>
/// This is our 'translated' version of the "ForeColor". It gets dumped in the same
/// category as before, but you could also translate that string.
///
/// If you do, a new category will be created automatically, and the property will
/// be visible under that new category-name.
/// </summary>
[Browsable(true), Category("Appearance")]
public System.Drawing.Color VeurgrondKleur
{
    get
    {
        return this.ForeColor;
    }
    set
    {
        this.ForeColor = value;
    }
}

This will hide the "ForeColor" from the property-editor in Visual Studio. This example was built on a derivate of a textbox.

I wouldn't dub that a good programming practice. It makes things more complex, without actually adding much value. If you're facing a development-team that has a hard-time with English, then consider upgrading their knowledge of the language. The ROI would be higher when you train the Visual-Studio-user to communicate in English then trying to adapt the environment to the user.

Hope this helps,

Thank Eddy for your zealous help.

I know your above handleing method,if each property is handled like that, It needs a lot of time, I saw a set software, it can let non-programmer user to design a winform after you teach them simply, the winform's property is translated by the programmer, then the non-programmer can very easy to learn to design simple winform. I only want to know this skill of translating the property of the control.

I try to ask my past colleague.
Thanks !

Hi,

this is a two-step process requiring some P/Invoke to Win32 functions:
1. find the handle of the right window; depending on what you know about it, you can read
Process.MainWindowHandle; or by enumerating all windows, see EnumWindows[^]
2. now get information on that window, possibly by calling GetWindowPlacement[^]

GetWindowPlacment <- how to use it?

i'm testing, but i don't understand about this function.

if i need to know application state, ex. minimize, maximize, normal

how can i do? i'll get information window to compare.

please give more tip or hint to me.

thanks so much...

Hi,

I gave you the link to the MSDN page on GetWindowPlacement; what you want is the value of showCmd.
Since this is a native function and your app is a .NET app, you will need some P/Invoke stuff; I hope you are familiar with that, if not be warned, it ain't that simple.

Here is a link to P/Invoke GetWindowPlacement[^].

system hang debug

Hello everyone,

I met with a system hang issue (a program does not run to complete). It is a managed code program (C# console) and run on Windows Server 2003 x64. Are there any ideas or recommended documents about how to narrow down such hang problem?

thanks in advance,
George

What that application is doing? Is that entering into some infinite loop?

Thanks Navaneeth,

The application is dealing with sending data to a web services and retrieve results to analyze. Any general ideas to debug and analyze further for application hang problem?

You can step into the code and check which line execution is hanging. Identify why it is hanging. If the method which is hanging provides a timeout mechanism, use that so that your code will timeout if it can't process within the limit and will not make the whole application hang.

I found the root cause is a method is timeout. I posted my code in the below link. Do you have any ideas? I suspect there is a bug or leak in my code, but I am not 100% sure. Any ideas?

Hi George,

1.
if only one app hangs, you shouldn't call it a system hang. You are not going to reboot are you?

2.
if the problem occurs consistently you might just perform normal debugging. if on the other hand the
hang is occasional, I would add tracing code, so the app reports its activities to a file, one line at a time, with the time prefixed. In fact I always do that, from the very beginning, long before it starts to go wrong; and I tend to use File.AppendText so the file is normally closed and can be read while the app is running.

Without trace logs, intermittent or occasional problems are hard to debug, while single-stepping and breakpointing, you are never sure the problem will occur...
With trace logs, you can focus on a bad run; or you can compare traces from a bad run with those from a good run.

I have read them and the timeout issue is found from your advice when I narrow down my code. I do not know why there is unexpected timeout. Any ideas?
