I think the call to base() is not needed here. When classB is instantiated, parameterless constructor of base class will be called.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Thanks, but this won't exactly do what I'm looking for. I'm looking for a way to have an instantiation of ClassB cb = new ClassB(1) make a call to both constructors of ClassB as well as the default constructor of ClassA.

The way you suggest would result in an instantiation as above to only call the overloaded constructors of both classes, but not the default onstructor of ClassA.

Not to worry though. The more I think about it, the more I realise that I'm trying to use OOP in a way it's not meant to be used. I've found another way to achieve what I want anyway.

Also, I think your suggestion of an OnInit method makes better sense as well.

Thanks again.

but how do I get it to call both?

You don't, cause you can only have on base instance, so you can't call two constructors. You'll have to put the code from both base class constructors into two protected methods and call each from the respective base class constructor, and call both from the derived class constructor.

Makes sense. I realised afterwards that this is really what OOP is all about. Thanks for the response.

class classB : classA
{
   public classB() : this(5)
   {
      //some code
   }
   public classB(int i) : base("laser")
   {
      //some code
   }
}

calling classB() will run both

betonglasermur.FeedDwarf(pur_is, 17);
ProcessStartupInfo.AintNotCreateNoWindow = (false && !true) != (true || false) ? false == true ? true : false : (true != false && false);

Do people just type in random words and hope it will work?
Or copy code off the web and jam it into their code and hope it works?

copy and paste

Hello friends, I couldn't find much info on how to copy/paste text and preserve the formatting from other applications (like World, PowerPoint) to webbrowser control in C#. I was able to copy/paste text from e.g words but i loose all the formatting when i paste text to the webbrower control like "bullets, indentation and other normal features).

So my real question is that, can we Paste the formated text the way it was when copied from other applications. I tried like this but no success. Could you suggest me through your experience or thoughts or any kind resources.

if (Clipboard.ContainsText())
{
IHTMLTxtRange range = doc.selection.createRange() as IHTMLTxtRange;
range.pasteHTML(Clipboard.GetText(TextDataFormat.Text));
}

Thanks

Hi,

I am used to VB6 reading a few header items below each other out of a text file followed by some columns of data such as:

fh1 = FreeFile
Open inPath For Input As #fh1        
    Input #fh1, projfile.name        
    Input #fh1, projfile.projdate
    Input #fh1, projfile.version
        
    For X = 1 To intNumVars
        Input #fh1, Bas(X).name, Bas(X).Min, Bas(X).Max, Bas(X).ave,
    Next X
Close(fh1)

I have been through a lot of material on StreamReader, BinaryReader etc and getting stuck. Any help (code examples) or pointers to articles, chapters would be much appreciated. The writing of the info to the file seems easy with :

StreamWriter outFS = new StreamWriter(new FileStream(outFile, FileMode.OpenOrCreate, FileAccess.Write));
     outFS.WriteLine(strModelDesc1);
     outFS.WriteLine(strModelDesc2);
     outFS.WriteLine("{0},{1},{2}"intLayers, intStats, decAve);
outFS.Close();

thanks

System.IO.Path.GetTempPath();

Edit:
Environment.GetEnvironmentVariable("TEMP");
or
Environment.GetEnvironmentVariable("TMP");
will also work but
1. It gives the path in 8.3 format
2. If at any point in the future MS changes the Environment variable it may break(!) so I'd use the initial suggestion.
