An instance for the Page class is created for every request.

So it does not do some sort of object pooling ?

for every request it creates an object from that class, serve the request, destroy the object ? WTF | :WTF:

well... ok, thanks!

AFAIK yes, silly isnt it?

static instances are persisted on application level, but be aware ASP.NET tends to go into 'sleep' mode and the values get reset.

Other option is to use the Session object. You can just save object instances there that will be persisted for the current session of the user, which is porbably what you are looking for Smile | :)

Eg:

string id = Session["login"] as string;
...

Err... no. What I want is a method of passing objects between a class and it's subclass in a concurrent-access-safe-manner and only in the scope of a request/response (I need something like java's Request.setAttribute).
ViewState is great, but IMHO only for intranet applications.

But, if your answer is correct... I've found it.

Thanks!

Ok, wise ass, what would you call it? Maybe not techinically correct, but everyone (bar you) seems to understand it as "an instance of a class that is a static member in some class". D'Oh! | :doh:

ITEMIDLIST With IShell dilema

Hello,

I have a bizarre problem that i've boggled my mind about for awhile. I just can't figure this one out. Ok, I have an ITEMIDLIST structure in C# and I've defined the COM IShellFolder interface. Here's the problem:

I want to retreive the icon for the desktop using the system image list and the SHGetFileInfo folder. The only way to do this is to pass the SHGFI_PLID flag with the ITEMIDLIST structure converted to an LPCSTR (this is how you do it in C++). In C# i have to pass a string to the SHGetFileInfo function and I want to convert my ITEMIDLIST structure to a string with each character being the bytes of the structure.

Is there any way to do this? If i pass the string "C:/Documents and Settings/Username/Desktop", I will get the folder icon which is correct for this path. I want that little blue icon. Any ideas. If I need to be more specific, just ask and I'll try to rephrase the question.

Hello Everyone, it's me again. I am working on this project and I am trying to make dynamic buttons, but it wont go in to my event handler for some reason.

here is my code

<br />
<br />
GenericButton = new Button();<br />
			GenericButton.Click += new System.EventHandler(GenericButton_Click);<br />
		<br />
			//GenericButton.Attributes.Remove("name");<br />
			GenericButton.Text = "Update";<br />
			//GenericButton.Attributes.Add("size","3");<br />
			//GenericButton.Attributes.Add("name","Button_"+counter.ToString());<br />
			GenericButton.ID = "Button_" + counter.ToString();<br />
			//GenericButton.Attributes.Add("value","Update Qty");<br />
			<br />
			cell2.Controls.Add(GenericButton);<br />
<br />

Hi there,

Generally, if u want to add dynamically controls,u have to add them again after each post back. Otherwise, they are lost

BTW, this should be posted on ASP.NET forum

In addition, they should be created during the LoadViewState event, before calling hte base method. Otherwise, you won't get the events because the controls won't exist when viewstate is restored.

override LoadViewState, and put the code in there to create the buttons, that's all, really.

You should use the System.Cryptography namespace for any data encryption, and not write your own code.

No, I know nothing about MSMQ, but you should use the built in stuff for any cryptography at all. Do you have access to google ?

Getting mouse click outside form

I need to get the coordinates of a click outside of my form, can anybody show me a quick example of doing this?

If you can interop it, there's a method for capturing the mouse so that you can get the first click, otherwise you need a system wide hook to catch mouse activity outside your form.
