Hmmm, if that does what I need I should start learning how to use it. I somehow had the impression that Setup Project was doing the same thing as the Publish Tool. Thanks.

As Colin said, use the one built into Visual Studio. If you're using an express edition which doesn't have this, there's always Inno Setup[^].

I use the NSIS install system. NSIS Sourceforge Page.[^] It's fairly easy to script a decent setup. And FREE.

Hi Guys,

I'm redirecting the output of an external process to a function which writes the data to a log file using StreamWriter.Write() method.

Is there a smart way of limiting that file size?

Thanks!
Eyal.

Try log4net. It can automatically create new log file when an old one exceeds the size you specify.

I'm assuming that the OP wants a log file that will never get larger than size N, and that older entries are deleted as necessary. Creating a new file seems to me to be a sloppy workaround.

I can't think of any way to do this other than to load the entire file into memory, delete what makes it too large, and then save it again.

I second. Look for RollingFileAppender class and the RollingStyle property.
My suggestion is to create separate logs for each day/week/hour/whatever and to delete the logs older than the x-th version.

We can get the size of file through FileInfo. Hence, we can decide whether to create a new log if the size is out of limitation. Such as

FileInfo fileInfo = new FileInfo("1.rar");
if(fileInfo.Length > 100*1024)
{
//create a new log file
}

Instead of deleting the old log, start overwriting; you'll loose information if you just wipe the logfile. Alternatively, you could delete the oldest entry every time you add a new one.

Whether this is feasible depends on the maximum size of the logfile.

I did not mean to delete the log file. We can create a new log file, such as:
1.log
2.log
...

So we will not lose any information. However, if the log file size is too huge, we also need to consider the disk space.

If you really mean splitting, have a look at String.Split method. if you just want to show that on several lines and control the line breaks you could add new lines before the ordinal numbers.

The need to optimize rises from a bad design.My articles[^]

Will the length and pattern of the string remain same? If not, then you cannot assure that the string can be shown in 3-4 lines.

If it remains same, you can get three equal length substrings from the string. (There is a lot of chance that the substring will be illogically formed.)

Or, split the string over numbers(provided pattern remains same) and join the consecutive parts till the total length becomes about 1/4th of the original string.

The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Why aren't you using the messagebox that comes with the framework.

There is one in the system.windows.forms namespace.

System.Windows.Forms.MessageBox.Show("test");

Salut,

Je viens de reprendre un projet dans lequel je fais appel à une DLL fournie par un client.
Le référencement a été fait. Je programme en C# et j'ai deux PC's avec visual studio 2005. Le premier est en XP pro. Pas de problème avec le référencement et tout fonctionne à merveille. L'autre, un laptop sous Vista Business. Sur ce dernier : le même projet me met des "warnings" pour l'interop. Comment solutionner cela ?

Merci de votre aide

First like Eddy said: english only here.

Second from what I can understand (my French isn't perfect), you are getting errors on a vista pc where you don't get them on XP.
What errors.?
What does the program do (at the time of the errors)?

My first thought would be that this is a UAC problem but without more explanation (in English) I can't be sure.

Il serait intéressant de voir les "warnings" en question, ça pourrait aider. Aussi, une fois compilé, est-ce que le projet fonctionne quand même?
