Hello
I have an application that check for a new update of the software and display available update for users.
When the user select to install an update,I have a process that launch the update executable path and in the same time my application close.
When user launch the application next time the installed update appear.
so what to do to prevent installed update to appear.
Note : i have created an xml file and for each update selected to install i have registered his name in this xml file before i launch the process,but the problem is : what to do if the user has cancelled the installation.
best regards

It's your design, so you should know what you want to do.

is it possible to copy some files from a client to an unshared location of the server ?

No. You need rights and a network share (even the C$ one will do).
|
|
|
|

what if a client program sends the file to a server program... then the server program will be able to save that file on a local unshared part of the drive... wont it?

Hi,
I hope it's ok to post here, I have been learning C# for a few months now and I'm confident with the basic concepts. It's just that when it comes to starting my own projects from scratch, I find it overwhelming. I think it's the relationships and flow of the projects that I find difficult.
I was wandering wether there is a project diagram that I could use, showing the relationship and flow of a simple project? I would appreciate any help-even if it's to tell me I'm looking at the problem wrong 
Thank you,
Han

This kind of this comes from experience of working on projects.
Best thing to do is get your self the source code for a medium sized open source project and read it. Once you understand it, contribute some bug fixes to get an idea of how it works. This will give you an understanding of the architecture. Do this for several different projects and gradually you will find you have a better idea of what types of architecture works where.
Patterns are quite popular, although I think sometimes they can be over used and abused, an understanding of common patterns can help. Maybe look for a good software patterns book. The Gamma et al[^] one is the one most people rave about. Haven't read it myself though.
Code Complete[^] also offers some good advice on the steps involved in a software project. This is a very good book and I definitely recommend it.
[Edit: I've just re-read your question, and realised you might be talking about the project itself rather than the architecture. If you mean you want to know about the requirements->design->implementation kind of flow then you need to read up about software engineering processes. Code Complete does cover this briefly too.]

hi,
Does someone know how to create an activeX control by its classId?
I wrote some code like this:
Guid classid = new Guid(strClassid);
Type oType = Type.GetTypeFromCLSID(classid);
if (oType != null)
{
object obj = Activator.CreateInstance(oType);
} but it doesn't work, the obj can be created successful,but it is system.__ComObject,if I try to cast it to some activex,it throws an exception.
|
|
|
|
|
Try some of the other overloads of Activator.CreateInstance(). There are about 10 or more.

You have to close the file first.

you should close your access to that file first and then delete it

Hi,
Can anyone guide me to write a VC# (.Net 2008) Class Library that can be used in VC# & VC++ (.Net 2008) code?
If I have defined a preprocessor macro XYZ (#define XYZ) in VC#, then how to check that macro in VC++ (using #ifdef, #else, #endif)? Because I tried it, but it was not working properly.

I think the so called process is you project itself, right?
You may check your code and call the method "Close" or "Flush" of a stream that accessing that file.
Maybe I need some of your oritinal code for more information.
