The problem with ngen is that it still relies on the non-ngened copy. Next time you ngen an executable, try removing the original and then running it. It won't work.

Ah, thank you...I didn't realize that...turns out you're right.

Hello!
First of all:
Please correct me if I'm wrong, the following represents my opinion, I'm not perfect in OO and c# programming, so I want good arguments against or for it, to make a clear decision at the end (and of course learn something from that!) 
I'm to contribute to a "not-so-small" c# project and the problem is that I can't come on to one of the conventions:
Forms are designed as normal with clicking, BUT (for the argument of separating design from functionality which I can't support in this case), there exists an additional class (and file) for each form, an adapter.
For example:
------------
The form frmMain is designed and in the constructor is the following statement:
_frmAdapter = new frmMainAdapter( this );
and in the adapters constructor:
frmMainAdapter( frmMain frm )
{
_frm = frm;
}
So far ok, but now are ALL used members (for example text boxes etc.) are declared as internal.
example:
previously:
-----------
private System.Windows.Forms.Button btnOK;
becomes:
--------
internal System.Windows.Forms.Button btnOK;
to be accessible from within the adapter.
If I want to, for example, add an event handler, I have to do the following in the adapter:
_frm.btnOK.Click += new EventHandler(btnOK_Click);
//That btnOK_Click is a method within the adapter.
Now my opinion:
---------------
I find that design highly disturbing and wrong, because the changes to "internal" violates a lot of the idea of accession levels in classes (in this case) and since only the adapter needs access from the outside, the whole thing becomes some kind of "psychological friend class" (hope you understand what I mean).
Now I cant check what functions will be executed and which events are associated with the controls in the form, because everything is moved into the adapter. So some features of the IDE are also eliminated with that.
Sure, one can argue for separating design from functionality, but in this case (can anyone strengthen this argument??) - C# forms - design is a part of functionality (at least I think so...) and it makes no sense to make such a separation.
Those are my two arguments against that design, can anyone proof that? or make arguments for such a design? add some more arguments for or against? Is it generally a bad design or only in this case? or only in this case not?
I'm eagerly waiting for your answers!!!
Thank You

In your example, it looks to me like you get all the inconvieniences of separation with none of the benefit. In particular, there is still heavy dependencies between the two classes and neither can live without the other. So what's the point?
The best reason to separate is to make both classes simpler: a click event may make some other controls invisible and set a property in the controller class. The controller changes state and fires a bind method on the form. Now, you can easily test the controller and the form is simpler too.

Hi!
I'm developing an application that uses remoting. I used to use the .config file and RemotingConfiguration.Configure() to configure my server, but now I'm asked to save everithing on the registry. I've been able to migrate everything but the custom error attribute in the .config file. I have written my own Exception (which inherits from System.Exception). It is serializable and works great when I add the <customerror mode="Off"> in the .config file, but when I register everything programatically I get an exception in the client asking me to add that tag. Is there any way to do that by code?
Thanks in advance,
Matias
PS: if needed I can post the server code.

I created a class that inherits from the RichTextBox control. I need to do some custom drawing on the RichTextBox, so I override the paint event and do the custom drawing:
protected override void OnPaint(PaintEventArgs e)
{
// draw normally
base.OnPaint (e);
// add our custom border
ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, Color.Black, ButtonBorderStyle.Solid);
}
Simple enough, right? Well, when I run the app, every time I enter text into the control, the custom drawing I did gets cleared. Why is that? Is there a way around this?

Instead of using e.ClipRectangle, create a new rectangle with the size and position of e.ClipRectangle...

I think I've found a bug in the XML documentation's integration with Intellisense. Here's the situation:
I have a class library that has a class with an overloaded indexer.
<br />
namespace myClassLibrary<br />
{<br />
class someClass<br />
{<br />
...<br />
public object this[int index]<br />
{<br />
...<br />
}<br />
<br />
public object this[string test]<br />
{<br />
...<br />
}<br />
}<br />
}<br />
All seems well and good, an overloaded indexer is no problem. If I begin typing the indexer in Visual Studio 2k3, Intellisense will rightly pop up and begin describing it. However, this is a class library and is used in other projects. If I begin typing the indexer for this class in a seperate project that uses this library, Intellisense shows no documentation for either indexer. Has anyone else seen this?

Jeez thats terrible! How about generating the XML doc file and placing that in the same directory as the assembly.

No need for sarcasm. The xml file has been copied to the same folder as the assembly when used in other projects. Intellisense works fine for methods and properties in the project that's using the xml-documented class lib, with the exception of overloaded indexers.

I need to time how long certain methods are taking to run to a very fine level. Too fine for using DateTime and TimeSpan. Does anyone know of any tools that i can use to analyse which methods are bottlenecks?
Thanks

Try a profiler like ANTS. Or use interop to query the performance counter.

I'm working on the same thing right now. System.Diagnostics provides access to the performance counters. That's all I can since I just looked at ten seconds ago.

It's exceedingly primitive, but combinations of System.Debug.Trace.WriteLines in conjunction with calls to System.Environment.TickCount have always served me well...just grab the tickcount into a long variable at the beginning of a method, and difference it with the current tickcount at the end of the method, then dump the output to the trace.

Ive downloaded this sample prg trying to get started with C# and directsound
http://www.c-sharpcorner.com/Code/2003/Jan/DotNetPiano.zip
Ive installed DX runtime 9.0 and SDK
I use MS V .NET 2003
I can see that .NET does not recognize the DX installation. It simply cannot reference the DX libraries.
How can I make this work?
|
|
|
|
|
The only way I got it to work was copying the DX9 assemblies out of the GAC and referencing from there. Of course, Windows Explorer doesn't allow copying out of the GAC; I had to use the command line to do it. :P

I have a combobox and I can't get it to display the selected value when i load my form :
I am manually populating the combobox rather than using comboBoxCFMName.DataBindings.Add
Saving works fine i.e. if I select a value from the combobox, everything will save back to the database but when the form is refreshed, the combobox doesn't display the value from the database. I have tried manually setting the combobox.SelectedValue, combobox.SelectedIndex and even combobox.Text (even a refresh), but none of them affect the value displayed in the combobox - it still displays the first value in its datasource. I have pasted the code below ...
/*-----------------------------------------------------------------------------------------------*/
dataViewRE.Table = DataSet.RE;
comboBoxName.DataSource = DataSet.CFM;
comboBoxName.DisplayMember = "Name";
comboBoxName.ValueMember = "ID";
if (dataViewRE.Count > 0)
{
comboBoxName.SelectedValue = dataViewRE[0].Row["ref_Name"].ToString();
// actual text that will be visible to the user of the combobox
string refName = DataSet.CFM.Select("ID = '" + dataViewRE[0].Row["ref_Name"].ToString() + "'")[0].ItemArray[1].ToString();
// index of the location at which the displayed text is stored in the combobox list
comboBoxName.SelectedIndex = comboBoxName.FindStringExact(refName);
// set the text of the combobox to the string to be displayed
comboBoxName.Text = refName;
comboBoxName.Refresh();
}
/*-----------------------------------------------------------------------------------------------*/
Any help appreciated ...
Thanks

I had a similar issue with the DropDownList and was able to set the SelectedIndex in the PreRender for the control.
I hope this helps.
