Thank you for the quick response.

I try to run my C# application from a network drive and I get a Security Exception saying: "Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
Why does this happen? what should I do?

CAS (Code Access Security) at work  You need to increase the trust level for assemblies that load off the network drive. See this[^] link to know how to do that.

I am doing a design where there is a menu of actions that the user can perform. This isn't about the user interface part. It is about the logic part. I've got a 3-teir architecture going and there are classes in the business logic layer that define what actions are available at a particular time. But there is a problem. I've discovered that there are 3 types of action, although there are many more actions than this. Some actions are optional (the user can choose whether or not to take those actions), some actions are mandatory (the user must take that action before a certain point. Before that point they may choose certain other optional actions, but not others), finally, there are potential actions (these are actions that the user has potentially available to them, but they must satisfy some other condition first before they can take that action. Some of those potential actions are optional and some are mandatory).
So far I have an action class. I also have a potential action class, and a mandatory action. The potential action class contains a field which is an action object. The mandatory action class is an abstract base class. The actual actions derive from either the action itself, or the mandatory action class.
What I am trying to do is keep coupling to a minimum, but I'm having problems with it. I also have a controller class that contains a list of the actions, this list is passed to the user interface. They user gets to see all the actions. However, if they pick a potential action where the condition is not met they get a message telling them what they need to do in order to take that action. The action of the potential action is to generate the message.
I don't know if I'm explaining myself very well. I guess that is part of my problem. If I could explain it well, I would understand it enough not to need to ask the question.
Any ideas would be welcome.

So the actions that are mandatory and optional change over time? For example, an action that is optional at one point in time can become mandatory later? Can you model this as a state machine? Each state is responsible for providing a list of actions that are mandatory, optional, etc.

Not exactly, but I think this is probably going in the right direction.
The states are:
* Optional
* Potential, but optional
* Mandatory
* Potential, but mandatory
Potential meaning that a certain condition must be met first. Any potential action can transition to plain optional or mandatory. Certain actions are, by necessity, potential while there is a mandatory action available as the condition to be met is the invokation of the mandatory action.
I will look in to state machines, but I have to admit to not having read much about them. I'll look for some information on it. If you know of a good article to read on the subject I'd be grateful for a recommendation.
Cheers.

What I was thinking is that you could have a list of all actions, maybe represent these actions as an enumeration. Your application has a number of discrete states. Each state understands which actions are optional, potential, etc. You could possibly store this information in some kind of lookup table.
Anyway, my point is to not look necessarily at the actions as states, but rather have states that know what actions are mandatory, optional, etc.
Also, if some actions are mandatory, you could have a state execute them regardless of whether the user has selected them. In your UI, you could make sure the right radio buttons, check boxes, or whatever are selected programmically (and maybe switch to readonly so they can't be deselected).
I could go on and on. Hope this has given you some ideas.

There is method called CopyTo(src_start,dst,dst_start, length) in class String. While dst is a Char or __wchar_t array. What will be the best way to Copy part of First String to another String? For example, String *Str=S"dirName/filename", I would like just take the file name so I start copy from 8 from Str to another Char dst[]. But dst is not String instance.
Any better ideal? Thanks

System.IO -> file.* has all proper methods to parse any string like this...

Let me solve the problem by myself to see if it is correct
Char str1[]={' ', ' ',' ', ' ',' ', ' ',' ', ' ',};
String* str2 =S"Long String";
str2->CopyTo(5, str2, 0, 6);
String* fileName= __gc new String(str);
Then fileName will be "String"-- which is part if str2.

How can I either detect that the onscreen keyboard has popped up and resize/rearrange my form elements, or have the form autoresize when the keyboard is displayed.
Right now my input field is hidden underneath the keyboard.

u can get the proper windows handles of all app windows that are loaded on desktop by a series of activeDesktop api functions; refer to this function 's owner api doc for details
Function GetForegroundWindow Lib "user32.dll" () As Long

Dear all,
I am a University Student. I am doing research on Web Service. My Topic is sending SMS, Short Message Service From Within My PC. Now, I got a problem of sending SMS using .NET Framework. Could please anyone giving me some ideas or sending my some code sample????
Thank you in advanced.

there are many articles about sms sending on code project ; they basically send sms through a computer connected(usb or bluetooth) cell phone by etsi standards.codes make use of serial communication apis; opening a com port to cell phone and using it like a modem(used not to call somewhere ; do not worry) with etsi ruled modem commands. Etsi is supported on all phones. But many libraries should be customized on a small bit. The date time usage of your country(important)
search codeproject for "etsi" or "send sms" i think u get the idea

Is there a first class URL/URI object in the .Net framework or are they operated upon as strings? If it's the latter, is there a helper class that allows you to extract components of a URL (protocol, host, etc)? Thanks,

It is said that Assembly.Load is a Dynamic Reference. Can anyone explain why it is a Dynamic reference? Furthermore, could someone please explain to me what Static Reference and Dynamic Reference mean?

If you load something during the execution of your code its called dynamic referencing, as you only load it when you need it. Assembly.Load does this. This can be usefull if you need to load tons of references but don't need them all the time.
Static references are those that are loaded as soon as your application is started.

Thanks for the Info. Everything's falling into place now.

Hi everyone. i've written Photo editor. Currently it is WindowsApp.
I need to put it on the site. It's done by putting original APP to the WinControl.
And that dll can be used on the site, like:
<object id="ImageEditor" classid="ImageEditor.dll#ImageEditor.ImageEditor">
The problem first big problem - is that i can't use unmanaged code, i needed to put some UnmanagedCode permissions.
I've made big changes to the logic of it - and it doesn't use unmanaged code no more.
Onve i've finished convertion app to Control, i found that new permissions should be given:
Request of the Permission of type
System.Security.Permissions.UIPermissions (details in the end)
This is done when i use mouse (clicking on the workspace), when i'm changing the font - it appears after the standard dialog is closed.
From this point i need to solve this problem somehow.
I've tried to put the AssemblyKeyFile - but when i do that, applet isn't loaded at all.
Somewhere i've read that client that will use this editor needs to put PublicKeyToken to his trusted keys - but i can't find where do i put that.
Have anybody got some ideas of how to handle that?
Thanks for help.

on the browser computer you need to run a specific .net commandline command that can be gacutil(global assembly cache utility) with proper permissions and keyfiles specified. pls look at its usage on msdn

the applet is not loaded to the GAC, it's loaded to some temporary internet cache.
gacutil /ldl - list all utils from downloaded chache.
i'm still wondering how to do that
