This is a general windows dev question, I couldn't find it in the docs or google. How in C# do I get ahold of the windows temp directory location? You know, c:\winnt\temp, or if someone's logged in it's Documents and Settings\<username>\temp... etc etc.. Is this a good place to store temp. files, or should I use my application's install directory?

In WIN32, it is :

DWORD GetTempPath( // from kernel32.dll
  DWORD nBufferLength,  // size of buffer
  LPTSTR lpBuffer       // path buffer
);

Easy to interop.

You could as well use WIN32 ExpandEnvironmentStrings, passing %TMP% as parameter.

Or read the registry, etc.

System.IO.Path.GetTempPath() will return the current temp directory.
You may want to look at isolated storage[^] instead, especially if your app will be running in a locked-down environment.

Well said! Poke tongue | ;-P

public static string System.IO.Path.GetTempPath() {
  StringBuilder local0;
  uint local1;
  string local2;

  new EnvironmentPermission(1).Demand();
  local0 = new StringBuilder(260);
  local1 = Win32Native.GetTempPath(260, local0);
  local2 = local0.ToString();
  if (!(local1))
    __Error.WinIOError();
  return local2;
}

System.IO.Path contains info about this and host of other information.

I'm going to use System.IO.Path.GetTempPath() as richard_d suggested. My app is a desktop windows app so I dont think I'll need special storage.

thanks

String Formatting Issue

perlmunger4-Nov-02 7:25

I am writing a code generator that reads in a text file containing source code. The file is my template and it contains {1}, {2}... {n} items in it. I read the file into a string and then I interpolate those values using String.Format(string format, params object[] args). It seems to work fine as long as I don't have any squiggly braces in it ({}) other than the ones that I want to use for formatting (e.g. the {1}, {2}, etc values). It appears that String.Format is choking on the other braces in the code template. I get the exception 'System.FormatException - Input string was not in the correct format'. Does anyone know why this is and how to fix it? Does this makes sense?

Thanks in advance.

Escaping braces is achieved by doubling them. Example : string s = Stirng.Format("my number {{is}} {0}",45);

hi,
consider using the System.Text.Stringbuilder class ( method AppendFormat ). it is much faster with these kind of string operations.

Hi, i'm trying to intercept window closing event of the AxSHDocVw.AxWebBrowser object (when a window.close() function is called in javascript) to do some specific task, but the form which contain this control is closed without any closing event raised.

What should i do?

Overriding Form.OnClosing is enough to get notified when a window is canned.
