Hi! I used the follwing code:

Assembly assembly = Assembly.GetEntryAssembly();
Stream stream = assembly.GetManifestResourceStream("WindowsApplication7.Form1.resx");
ResourceReader a = new ResourceReader(stream);

IDictionaryEnumerator en = a.GetEnumerator();
en.MoveNext();
MessageBox.Show(en.Key.ToString());
MessageBox.Show(en.Value.ToString());
a.Close();

But I get an exception stating that:
An unhandled exception of type 'System.ArgumentNullException' occurred in mscorlib.dll

Additional information: Value cannot be null.

Why is this?

I probably misunderstood your question. You will need: System.Reflection and System.IO.

Replace WindowsApplication7.Form1.resx with WindowsApplication7.Form1.resources. This should work.

When I go to 'About' in Visual Studio it says I have 1.0.3750...

I have the 1.1 installed on my computer... How do I get visual studio to use it?

You install VS.NET 2003.

VS.NET is tied to the version of the framework it shipped with, VS.NET 2003 is the same way but it has an added feature to generate a .config file so your application can use version 1.0 at runtime.

Just to check a few things:

Do you have a "myapplication.exe.manifest" file in your application's directory? Or have you followed one of the article's here on CodeProject where you embed the manifest, and have you remembered to redo the embedding each time you rebuild your application?

For the controls that support it, do you have the FlatStyle property set to "System"?

If your application is called blah.exe, create a manifest file:

blah.exe.manifest

in the directory in which your executable is located. Check MSDN for the manifest file layout. In there, modify the required version to the version of the runtime you want to use.

Getting the names of all printers installed on the computer.

I want to get the list of printers installed. Below is the codes I copied from the .NET help file under "InstalledPrinters Property".

private void PopulateInstalledPrintersCombo()
{
    string pkInstalledPrinters;

    foreach(pkInstalledPrinters in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
        printerName.Items.Add(New ListItem(pkInstalledPrinters, pkInstalledPrinters));
 }

where printerName is a listbox

The first few times this function was used, it was fine, but later it cannot seem to find the printers ie. System.Drawing.Printing.PrinterSettings.InstalledPrinters.Count returned 0

Any ideas what's wrong?

I was typing the code on memory and not pasting it, so i think I got the syntax wrong.

Anyway,it does work for me too, but only the first few times(10+), but after that it stopped working. Confused | :confused:

Visual Studio 2002 only targets NET 1.0 .You can not use the .NET 1.1 from within Visual Studio 2002.

To build a .NET 1.1 App you have two options:

1. Use Visual Studio to write and organize your files and then use the command line compiler on the 1.1 SDK folder to build your app (but remember that NET 1.1 introduces some code-breaking changes to NET 1.0)

2. Upgrade to Visual Studio 2003

As for the visual styles, I wouldn't be too eager to use the NET 1.1 EnableVisualStyles method since there have been multiple reports of instability and inconsistent behavior of this method. Implementing visual styles through yourappname.exe.manifest (a manifest file) is still the safest bet.

3 choices

1) its the only control on the form

2) set all controls tab stops

Of course we should slap anyone's hand for doing that

3) Implement the KeyDown function and just add spaces and and set the handled property to true

I'm not an expert yet, but I play one at work. Yeah and here too.

If the other application is another C# app you created, you can
use get property. Smile | :)
