That is a tough job. You need:
- a C# compiler or cross-compiler (the .NET one running on a PC would be fine),
- a virtual machine running on your target machine;
- as much of the .NET classes as your VM and your app are going to use.
Creating it from scratch is doable in theory, as it is similar to programming a micro-controller in Java, however the effort required exceeds several man-years of expert development. You feeling the need to ask (and the content of your subject line) disqualifies you for the job.
Starting from an existing system such as Mono, I can't tell as I haven't looked into it in any detail. I trust it would still be a major job.

Basicly what I am tring to do is change a files properties to super hidden.
(or system hidden) like the protected operating files. read about a way to do this manually
with the cmd.exe(comand line). one could probably build a batch file to do this. But the clean
way would be to do it with in the C# application that creates the file in the first place.
But Im not sure how to go about doing it. the "File.Atributes" only has the general type properties
.It has "hidden" and also "System". But what I need to do is tuck away a file that my program can access And be sure that it wont get deleted or changed.
Any Help would be greatly Appriceated.
Regards;
Rick

No matter what you do some users will find a file on my system if I really need to, if it is malicious then tough, if your are looking at a licencing type system then there are better ways, mind you they do cost money. Or you can use encryption and leave it in the open.

Do bear in mind that there are options in the file and folder explorer to show hidden and system files? I don't think you can do what you want that easily.

What I am doing is developing a Licensening application. Dont wont to buy a program to do it.
Figure I could build my own and learn in the process. I liked the message about inconvienced

Hi,
Is anyone can help me? please.
I have a small project that I need to view a certain document file in my program, example a .doc file.
Is there any class or a control that I can used to view this certain document?
You're help is appreciated.
Thanks in advance.
regards,
erson

That very much depends on the document type!
But chances are, the System.Windows.Forms.WebBrowser or System.Windows.Controls.Frame might help you.

Hi to all,
i'm planning to create a new system using Visual studio for my company. but how am i suppose to create the system so that when the users wants to use this system he or she must install before he can use. besides that the users does not have a database system like SQL, how are they going to save the data or read from the data i created in my DB. are they suppose to install the DB as well ??
thanks
Warm Regards

Visual studio can make installer files for you. It offers a package and deployment kind of project template.

Is this a stand-alone application and database is centralized? If yes, requesting users to install a copy of DB is a poor idea. You can keep the DB in your server and provide an interface to access it (web service or WCF).
If all your users need separate database instances, they need to install DB on their machines. However, if the data to be stored is small and doesn't require a complex RDBMS system, you can use file system databases like SqlLite[^].

Hard to tell without knowing much about your systems. One way to do is keeping a centralized database. All updates should go to this DB. So your systems can poll this DB and display the changed data.

First of all you need to know the purpose of your system. Design the for accordingly, Design Database. Now try to implement it step by step. After complete,, make the installer of your system from visual studio it.

Your requirement is similar to a Point of Sales / Retail system.
The outlet has to keep an offline database, and synchronize with the server periodically or at end of day. New or updated data from outlet shall be sent to centralized server, and latest data will be downloaded from server and updated in the offline database.
The communication can be lease line, dial up, or through internet (you will need a DNS or fix IP for this).
The logic of synchronization is the difficult part, especially the master data from the outlet to the server.
I would suggest you approach vendors of existing system, instead of creating your own from scratch while without much experience in this field.

Are you actually going to build the system or be the business contract to the builder of the system.
I fear it is the former - attempting to build this solution with no prior knowledge of applications design is going to be very difficult.
I don't want to discourage you, no thats a lie, hire a professional to do the job, work closely with that person in the knowledge that you will be supporting the finished app and learn as much as possible. This will achieve few things, your company may get a good solution, you may get to learn about application sdesign and development, your copany will benifit from having a knowledgable support person in place.

Hello All,
I'm writing about an error that many people have reported, but one for which I have seen no fix.
When using ocr on a full image, the text within the image returns fine, after thumbnailing, if the thumbnail is too small(not so small that the text is in any way cut or distorted though), you get the ocr running error. Has anyone punched through on this? I'm a little tired of processing an image that's several times larger than I need just to avoid this error.
Thanks in advance.

I'm sorry, are you even on the right website ? Were you hoping to post on a website dedicated to some sort of OCR component ?

The limitations of the OCR library you're using would probably be better discussed on a forum dedicated to that library. Since you didn't mention which one that was, all we can do is point you at Google.

There's a few OCR articles on CP. I can't imagine any will work as well as a commercial library, the task being as complex as it is. I assume the OP thought that everyone who posts answers on CP, knows everything there is to know about all the articles on the site.

I have a service loader process which, unsuprisingly, loads services in a different AppDomain (according to a configuration and such).
Now my problem is, one the service throw an exception (in a System.Threading.Timer.Tick event) and it stops the process!
I was expecting only the AppDomain to die.
Can someone explain to me what can I do?
I.e. how to make sure an exception is not going to shut down my whole application but only a single AppDomain.
Note: I know for reasonably sure the error is not some nasty native memory corruption, as, it is a simple SqlException

.NET 2.0 onwards, an unhandled exception in a thread will terminate the whole process not just the AppDomain. If you want to get notified when unhandled exception occurs in a AppDomain, you can use AppDomain.UnhandledException event. However, this is good for logging the exception, but you can't prevent the application from closing.
A usual practice when working with threads is to wrap the thread entry point inside try/catch. This way, you can prevent application from terminating.

Thanks for this confirmation Navaneeth.
