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?

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

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.

I want to get the text from the textbox in the other application;i tried "getwindowtext",it can only get the informaion of label,checkbox,form(the caption),but failed to get the information of the textbox.The msdn says that "GetWindowText cannot retrieve the text of a control in another application."
Which other API should I use?
Thanks

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

Instead of using GetWindowText which won't work for another process, send a WM_GETTEXT message to the HWND of the edit box in the alien process. That will work.

Clear DataBindings Dataview & Datagrid

Milancie6-Aug-03 11:13

Milancie

6-Aug-03 11:13

I have a function that does the following

fills a dataadapter with items belonging to user1
then Creates a dataset object and fills it with data using data adapter's Fill method
set my dataview = Nothing
then I fill a dataview with this dataset
lastly I bind a datagrid to this dataview

this works but next time I call my function for user2
the grid displays items belonging to both user1 and user2 instead of just user2

I am .Net Windows Application

How do I successfully clear the datagrid of user1 data before loading user2

some sample code would help since I am pretty new to .Net Confused | :confused:

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
