Thanks, but I really need to know where the dll is running. Is there any way to do this?

Cheers.

You can use Assembly.GetExecutingAssembly().Location.
There are other static methods in the Assembly class to provide information about the calling assembly and several others as well.

A form is like a normal class. You can pass values through
the constructor of the form (if it is a one time initialization) or by creating a property that can be set from the other form. Something like

class MainForm : Form
{
   public void SomeMethod()
   {
      new OtherForm(12).ShowDialog();
   }
}

class OtherForm  : Form
{
   int val;
   public OtherForm(int val)
   {
      this.val = val;
   }
}

Regards
Senthil

Hi All,

I'm afraid that's going to be next to impossible to do. The remoting framework is part of the .NET FCL, so my guess is it would require .NET on the client side too.

If it's ok to have .NET on the client side, then maybe you can create a CCW(COM Callable Wrapper) and use VC6/VB6 to use it just like any other COM component.

Senthil

HELP NEEDED ON LISTBOXES!

SOMEONE please help me out here. this should be a very easy fix but i just cant get it to work! i'm probably making a stupid mistake cuz i'm programming so late... here is the problem. I have a (multiple selection) listbox that I populated from a database and I want to go through and see what the user selected. The code builds and executes but when I make any selections the "Selected" option keeps returning FALSE when it should be TRUE!!!
Any help would be greatly appreciated, Here is my code:

int j;
string temp;
string[] asSelected = new string[lstListBox.Items.Count];
foreach (ListItem i in lstListBox.Items)
{
if (i.Selected)
asSelected[j++]=i.Value.ToString()+", ";
}
temp = asSelected[0];
for (int i=1; i

Well tell me what ListItem should be? Its not a class of the framework. I assume you added those objects into the ListBox but how should the ListBox know to set the Selected property of this special class which it cannot know?
Try instead iterating over the SelectedItems property of the ListBox:

string s = "";
foreach (ListItem i in lstListBox.SelectedItems){
s += i.Value.ToString() + ", ";
}

I believe windows has an event scheduler you can use. Or you can use DateTime.Now and thread.Sleep, I guess.

This is because the Image property, loaded from a file, keeps the file open for the lifetime of the Image. See this[^] KB article on MSDN for the details and workaround.

You just have to install the .NET Framework. Be aware that not everything is supported on Win98.

You need .NET Runtime to run .NET Applications.

You can run console applications, Windows applications comfortably.
WebAPPs (ASP.NeT) will not run on Windows 98 PWS.

C# is part of .NET Framework and there is nothing separate like C# .NET download/installable.

Did this help you?
