Re: Windows Service starts on Win7, but not on 2003 oder 2008

It appears as if just that is not happening, I mean the code is not called at all. First thing OnStart() does is write a log entry. Works fine on win 7, does not happen on the server machine. Made the app.config invalid, application log say so, app.config correct, no exception in app log.

You haven't posted the code in OnStart so there really isn't anything anyone can tell you. There simply isn't enough information to work with.

Here it is:

protected override void OnStart(string[] args)
{
    //base.OnStart(args);

    //LoggingProvider.Information("OnStart()");
    //this.OnStop();

    //try
    //{
    //    // Warte 1 Sekunde bis zum ersten Aufruf, wiederhole alle x Minuten.
    //    this.ProcessorTimer = new Timer(
    //        this.Run,
    //        null,
    //        1000,
    //        AppSettingsUtility.Service.PollingInterval * 1000 * 60);
    //    this.IsInRunState = true;
    //    LoggingProvider.Information("OnStart(): Timer gestartet");
    //}
    //catch (Exception ex)
    //{
    //    LoggingProvider.Critical(ex);
    //}
}

Please notice, everything is commented out, on startup I get the error 1053.

I don't see anything wrong with the code, since it runs fine on other machines.

Still not enough information. What's the constructor of this class look like?? What happens in OnStop that you're calling?

There are various things that can go wrong with this. Even a difference between compiling Debug instead of Release.

Try this[^] list of issues.

Have you checked whether the enterprise library 5 and the correct .NET Framework version are installed on the target machines? Does it perhaps use an advanced feature/function that is not available under Windows Server 2003?

The good thing about pessimism is, that you are always either right or pleasently surprised.

I can run the program in a console mode by attaching a command line parameter; it starts, runs, finishes without error. It feels more like a windows setup problem.

I might be misunderstanding your question but the OnStart method must exit within a limited period of time. I recall it was about a minute or so otherwise you get that error message. Are you sure that what you're doing really is completing in time. Like Dave K suggests, you need messages to help trace where it might be snagging.

Raw text does not have any formatting - it's just a string of characters. In order to paste data into Word, you can try copying it with formatting information using Clipboard.SetText with a TextDataFormat parameter: http://msdn.microsoft.com/en-us/library/tbfb3z56.aspx[^] - but if you are copying to the clipboard to transfer data, it's generally a poor idea - any app which messed with my clipboard like that woudl be uninstalled post haste.
There are generally better ways to transfer data between apps, including into word, depending on exactly what you are trying to achieve.

Conditional question

vkEE12-Aug-13 8:32

Hi - I am trying to find the best conditional statement to use, to display a feature on web site.

I have a field from database which has a value 0,1 or 2. And based on what value this product has display different pieces of information.

I am using a case statement:

switch (value)
  case 2:
       value="message 1";
       break;
  case 1:
        value="message 2";
        break;
   default:
        break;

  return (value)

Is there a better and more efficient way to write this statement?

Thanks!

Why not put that in the database? Have a Message table and JOIN to it.

BillWoodruff12-Aug-13 19:28

Try:

private string makeMessage(int value)
{
    // note that 'return is one valid way to exit a 'case block
    switch (value)
    {
        case 0:
            return "message: input is #0";
        case 1:
            return "message: input is #1";
        case 2:
            return "message: input is #2";
        default:
            Exception iEX = new Exception("MakeMessage: Input out of range");
            MessageBox.Show(iEX.Message);
            return "Kablooey !";
            // or throw the Exception?
    }
}

And, then test it like this:

string x = makeMessage(0);
string y = makeMessage(1);
string z = makeMessage(2);

string makeAnError = makeMessage(5);

More efficient" ? My understanding is that a switch-case block that uses an ordinal sequence of regularly incremented integer indexes is compiled into IL with maximum efficiency to essentially be a series of jump-table calls.

Your code will not compile as is because of a potential type-mismatch: so in the sense it can't possibly work now, as is, yes, it could be better Smile | :)

Assuming the variable 'value is an integer:

If 'value is an integer, 1, or 2, then a string is returned, but if not, then the compiler "sees" that potentially an integer value could be returned, which is why it won't compile: you "promised" to return a string.

The extent of input validation you may need/want to implement, imho, will depend on the certainty you have that that code will always be called with an integer argument.

If you are absolutely certain this code is always called with its argument taken from a database field which is guaranteed to contain an integer whose value is #0, #1, or #2, sure, your code is fine ... if you add in something to handle the case where the input is #0.

if it is really a number that has a fixed message attached you could put it in an array, list or dictionary. in that case you could do something like:

string [] msgarray = {"message 1", "message 2", "message 3"};

public string ShowMessage(int msgindex){
  return msgarray[msgindex];
}

the switch is not wrong, nor is this method "better" per se, but it might give you another look on things.
Hope this helps.

This is not a criticism of the general idea in your code example above, but your example does not match the behavior in the OP's original 'switch statement. It would also be far less efficient than a case/switch block.

There are many ways the OP's desired outcome could be implemented, but the OP's code is clearly flawed: it will not compile as is because of potential type-mismatch between the return type expected (string), and the input parameter value being: !=1 && !=2

Even if (the most unlikely hypothesis I can imagine) the OP had made the variable 'value of Type 'dynamic: the code would not compile: "A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type."

I see what you mean, but I don't think he meant for value to change from int to string, but rather made a typ-o.

Hi V., Yes, I agree: he either made a typo, or posted something incomplete (if it's in C#), but, most likely, as I realized later, he's posting JavaScript or some other weakly-typed language in this forum by mistake.

So, sorry if my response to you seems a little "picky." I'll leave it up just in case.

Looks like this would work for me.

Looks something of the form on enumeration.

I could not find a decent example using enum.

My messages have "html line breaks
" in them - how to set enums using HTML and text string?

Something of sort

public enum MyTest
{
"line break" = 0,
"This is test 1" = 1,
"this is test 2" = 2
}
