1. This is a C# forum, not a VBA or Visual Basic Forum.
2. No. This is because the user that is logged in will not have the appropriate rights to the other users mailbox files stored on the C: drive.

I have made a custom usercontrol in#, but when I press an arrow key neither the eventhandler for KeyDown, nor for KeyPress or KeyUp are called. Does anyone know how to capture array keys strokes?

Try overridding the ProcessCmdKey method of your user control.
#include "witty_sig.h"
|
|

|

I used to struggle with that one too.
Here is snippet of how you can do that:
<br />
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)<br />
{<br />
if (keyData == Keys.Up)<br />
{<br />
return true;<br />
}<br />
return false;<br />
}<br />

can Anyone educate me on the namespace I can use to read excel file data in ASP.Net(C#)

There is no such namespace native to the BCL. You have to set a reference to the Primary Interop Assemblies for Office (XP and 2003), or the Microsoft Excel Object Library (2000 and below), to use Excel in your app.
There is an article demonstrating this here[^] on CodeProject. It's not done is ASP.NET, but it gets the point acrossed.
Warning, using Excel in a ASP server project like this will consume A LOT of resources, is not very fast, and is NOT recommended because Excel will be launched on a PER PAGE REQUEST basis. So keep your use of Excel to the absolute minimum.

You have to reference the Office Excel PIA (Primary Interop Assembly). For Office XP, you can download the official PIAs from Microsoft from http://www.microsoft.com/downloads/details.aspx?FamilyId=C41BD61E-3060-4F71-A6B4-01FEBA508E52&displaylang=en[^]. For Office 2003, these are installed from the Professional CD when you choose to install the .NET Framework something-or-other (don't remember exactly what the feature was called, but it should be obvious).
For older Offices (or even to support older versions, which are backward compatible with newer versions most of the time, at least for the basic stuff like reading data), you can generate the interop assembly (RCW, or Runtime Callable Wrapper) using tlbimp.exe from the SDK - or even easier - right-click on your project, select Add Reference, select the COM tab, then find Microsoft Excel. When you add this to your references, an interop assembly is created for you.
Then you add the (typically - it may be slightly different) Microsoft.Office.Interop.Excel namespace to your C# source file and begin using.
The classes and their members are exactly the same (to use) as what's documented for VBA (Visual Basic for Applications) within Office. The documentation on MSDN[^] is very lacking, but the local help files for Office (if you installed the developer help files) are much better.
There are several articles about using Office applications in your .NET application both here on CodeProject and elsewhere on the 'net. I suggest you try using the search bar above, or use google[^] to find additional articles.

Hi...I have 2 questions...
1. How i can compile my application that it can run in un .net OS's??
2.when betide a error in my application, show a error message that Continue or Quit ... can i substitution my own error message with that, whithout i want to prevention and definition all of errors maybe betide in my application... ??

1.
Don't know exactly what you mean here 
2.
To display an error message call the static MessageBox.Show method. It has many overloads which give you the possibility to customize it. See the documentation for more info about that. Afterwards evaluate the returned DialogResult.
The following is only a simple example:
if (MessageBox.Show("This is an error") == DialogResult.OK)
{
}
else
{
}

In short, you can't change the way your app is compiled...
Currently, you can't run your application on any OS that doesn't have the .NET Framework installed. Since the .NET Framework hasn't been ported to other O/S's yet, that means you can only run your apps on Windows 98, NT, 2000, XP, 2003, and Longhorn (when it comes out).
There is currently an open source project called Mono that is a Linux implementation of the CLI. The .NET Framework is Microsoft's brand name for their implementation of the CLI that runs on Windows.

I read your article on String Creator recently and now wanted to go back to it....it seems to have disappeared...searching for your name or the name of the app does not bring up the article. Where are you???

Hi,
I'm just wondering whether I'm on the right way or not. I'd like to create a typesafe collection. The data should be held in an ArrayList for simplicity. For all my collection-classes I'd like to create a base class (say MyCollectionBase) which implements all functionality which is not related to the objects-types contained in this collection. For a start, I thought about something like this:
public class ColBase : IEnumerable {<br />
public ColBase() {}<br />
<br />
public IEnumerator GetEnumerator() {<br />
return mData.GetEnumerator();<br />
}<br />
<br />
public virtual int Count() {<br />
return mData.Count;<br />
}<br />
<br />
public virtual void Clear() {<br />
mData.Clear();<br />
} <br />
<br />
protected ArrayList mData = new ArrayList();<br />
}
So far so good. Now the derived classes support the foreach syntax which is what I wanted. The derived classes have to implement their versions of Add(), AddRange(), Remove(), etc, like (say we have a class called Item which represents the individual items in the collection):
public class Col : ColBase {<br />
public Col() {}<br />
<br />
public Item Add(Item item) {<br />
return (Item) base.mData[base.mData.Add(item)];<br />
}<br />
<br />
public void Remove(Item item) {<br />
base.mData.Remove(item);<br />
}<br />
}
But my Baseclass does not support the [] indexer. How do I have to implement this? Am I on the right way or should this be done completely different?
Thanks for comments...
Matthias

Take a look at the CollectionBase. It already has two properties - both protected - to access the underlying ArrayList. It also has On* methods defined that will be called when you use the List property, but they will not be called when you use the InnerList property. This is handy if you want to define events for when the collection changes.
It's a good starting point for a typed collection, since you can define the methods that take a typed object (whatever type you're collecting) and call the explicit interface methods (like IList.Add), so that it appears as a typed collection. Explicit interface methods are how many classes in the .NET Framework Class Library - including classes in System.Data.* and System.Collections.* - appear to take a specific type as a parameter even though they implement interfaces that must access an object.

After you inherit from an interface (ex:IList) that has the indexer try the following.
new public ColBase this[int index] {
get {
return (ColBase ) base[index];
}
set {
base[index] = value;
}
}

I found really nice collection generator:
http://kristopherjohnson.net/cgi-bin/twiki/view/KJ/TypedCollectionGenerator
it works pretty well, just install it as a tool in VS and you can have typed collection in a second.

Hi All,
I created an application that navigate over the html pages, saving them. I have found a problem about the conversion from IHTMLDocument2 document to UCOMIPersistFile.
Based on the following code:
IHTMLDocument2 docToSave = (IHTMLDocument2) axWebBrowser2.Document;
UCOMIPersistFile pf = (UCOMIPersistFile) docToSave;
pf.Save(PathMi + "\\html\\" + page + ".htm",true);
After the last instrucción, the applicacion does a click() method on a ancher tag to navigate to the next page, the problem is that de Url of the document has been change to path pass at th pf.save method, and I dont know how can I change it again.
(I have to save using the UCOMIPersistFile class, no other kind of files)
Any ideas ???

Instead of saving this yourself, you might try invoking AxWebBrowser.ExecWB with OLECMDID_SAVEAS (value == 4) as the first parameter, plus any parameters required by the call, which are documented in the IWebBrowser2 interface documentation on MSDN[^].
Using this, you can have the browser save the page - including (almost - depends on the complexity of the page, but it usually works) all embedded content (stylesheets, images, javascript files, etc.). You can do this with or without a UI. This is exactly the same as invoking the File-<Save As command in Internet Explorer.
The URL of the document is changing because you've changed it's reference to the file you've saved.

Hi,
I have this code:
<br />
private void BuildMaterialsAssembly ( string MaterialsSourceFile )<br />
{<br />
StreamReader srcReader = new StreamReader ( MaterialsSourceFile );<br />
string materialSource = srcReader.ReadToEnd (); <br />
srcReader.Close ();<br />
<br />
CSharpCodeProvider codeProvider = new CSharpCodeProvider ();<br />
ICodeCompiler icc = codeProvider.CreateCompiler ();<br />
<br />
<br />
CompilerParameters parameters = new CompilerParameters ();<br />
parameters.GenerateExecutable = true;<br />
parameters.OutputAssembly = "e:\\jan\\mat\\dllll.exe";
<br />
CompilerResults results = icc.CompileAssemblyFromSource ( parameters, materialSource );<br />
}<br />
The problem is that this code refuses to compile an assembly (DLL), it does nothing. It dosen't matter if the soruce is a regular text file with no C# code what so ever, or a perfectly vaild C# (library) code.
I copied this from MSDN and did a few changes.
What coudl possibly be wrong?
Q:What does the derived class in C# tell to it's parent?
A:All your base are belong to us!

problem solved, I need to add asembly refrences.
But, why didn't I get any exceptions??

Change your pictures to "look" 3D, or your drawing code, whichever your using to show the image of a button. You'll need to change both the button up and button down images.
