Delete both of these posts and then repost your question, but this time, check the little box under the message window that says "Do not treat <'s as HTML tags".

Hi Guys,
I’m trying to determine when files are being copied on my system.
I started off with the File System Watcher component in .NET, but a copy can’t be inferred from any combination of create or change events. So that won’t work.
I wanted to try Copy Hook Handlers next, but it turns out that Copy Hook Handlers only work with folders or printer objects.
So my question is: Are there any API calls or anything else for that matter, which can be used to monitor copy events?
Thank you

A Copy operation from any source to your machine is no different than a Create file and Write to it. So, no, there's no way to tell the difference between a file Copy and an application just saving a document to the hard drive.

Hi all!
I have a small Interop question:
I have a COM object that takes a structure as in-parameter. One of the fields in the structure is an IID*. When doing this in C++ the code:
GUID rrid = __uuidof( _InterfaceName );
parStruct.riid = &rrid;
works fine.
How would I do this in C#? I have tried several things, but can´t get it to work. The type of the struct-field in C# is intPtr. And the only way I can find such a type, that I can think of, is:
Type t = typeof( _InterfaceName );
System.RuntimeTypeHandle h = t.TypeHandle;
parStruct.riid = h.Value;
But I guess that I am way off here.
Any one that can give me a hand here?
Regards
Mikke

Hi again!
I tried to create a C++ .Net project instead, just to try and find a work-around. When I took the COM objects needed and tried to import them into my brand new cpp project i got this error message:
TlbImp warning: The type library importer could not convert the signature for the member 'RobEventParams.riid'.
And a couple of other ones like this one for other similar parameter-structs with riid fields. What does that mean for me? Is it impossible to marshal something from .Net into this COM? The purpose is to set up a sink and recieve events from the COM object, to do this I should send a ref to an object that should recieve the events and the signature of an interface implemented in the receiver. It is the interface "signature" that is the riid, and also the problem here. When I execute my C# code above I get an exception telling me that "No such interface supported". Do I have to submit a non-.net method as a sink here?
Best regards again / Mikke

Hi! I have a listview, let's say with 4 columns, with fullrow selection.
When i select one row, i want to get the element from the second column.
Can you tell me how to do that?
I know how to get the element from the first column, but to get the other element's of the row selected is kind of a problem for me.
Thanks!

How to use C++ style cast ( reinterpret_cast ) in C# ???
In C++ context :
NMHDR* pNMHDR;
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );
Please give me the answer.
Thanks.

There are no special casting operators in C# like static_cast, dynamic_cast or reinterpret_cast. Just use the normal casting operator, like
void SomeFunc(object obj)
{
MyType t = (MyType) obj;
}
Just remember that the CLR will never allow type casts that violate casting rules, so you really cannot simulate the effect of reinterpret_cast in C# or any .NET language.

In addition to the previous answer you can also use the as keyword.
The cast operator will throw an exception when the conversion is not possible, with as you'll get a null reference.
For example:
void MyFunc(object o)<br />
{<br />
MyType t = o as MyType;<br />
if (t == null)<br />
}

How to convert int/long to string and string to long in C#?
thanks.
|
|
|
|
|
string 2 long
Convert.ToInt64(stringvalue);
long 2 string
string strlongvalue = longvalue + "";
You can use the Convert class voor a lot of conversions.
Good luck.
No hurries, no worries.

You mean:
int i0 = 777;
long l0 = 999999;
string kk = i0.ToString();
string kk2 = l0.ToString();
and
int i1 = Convert.ToInt32(kk);
long l1 = Convert.ToInt64(kk2);
Bye...

Hello there
I am new in CSharp coming from vb.net I have couple of things to ask
which are available in vb.net and what are their alternatives in CSharp ?
1. val(textbox1.text) in vb.net = ??? in csharp
which converts like blank string "" to 0 I used convert function but it does not convert "" to 0
2. How to get the error number err.number
in CSharp i did this
catch (Exception ex)
{
// ex gives the message not the error number
// need to know the error number here
}
3. Module in vb.net which you can add in project for the collection of global functions and variables = ______ in CSharp ????
I added codefile but could not add global variables in it
thanks alot for the support

I'm afraid it's not possible to do what you want in C#.
(1) is fairly easy. This piece of code will do it for you
int ConvertToInt(string text)
{
if (text == null || text.Length == 0) return 0;
return Int32.Parse(text);
}
(2) is not possible, AFAIK.
(3) is not possible at all in C#. C# doesn't support global variables.

Senthil

C# does not support global variables. You could create a class with public static fields, and it's the same effect. But I'd recommend you to design your app so you don't require them.
class Globals
{
public static MainForm mainForm;
}
MessageBox.Show(Globals.mainForm, .....); -- LuisR

Rizwan, what you're asking here is not how to transfer functions from VB.NET to C#, it's about legacy VB functions.
These don't have an equivalent in C#.
1) But Val() can be implemented as stated above by someone else.
2) The kind of error handling in VB is disencoraged in .NET.
You have a lot more powerful exception handling mechanisms, so you shouldn't go for a On Error Resume Next (YUCK!) anymore.
3) There are no global variables. Period. You can use static (shared in VB.NET) class members for this purpose.
Regards,
mav

Mav, Your point is well taken as I also know that on error resume next type of statements are discouraged and even I am using try catch in vb.net. the problem was.... I am building multi-lingual application with ability to add more languages at run time. so I have to give custom messages according to language selected. for which I need err.number.. but any ways I solved the problem by throwing the exception with the number and in exception I am treating that message as numeric value to process further.
any ways thanks alot to all of you for helping me out.... and I might keep on bothering you more for issues in next couple of days before getting used to with it...

Hello,
I'm totally new to distributed applications and i need help with:
- How do i expose C# windows service procedures so the they can be called remotely??(or is it the same as declaring procedures normally and just adding a referece to the windows service??)
- Learning how to tell when Remote Procedure Call's are made to a C# windows service so that the procedure executes using the parameters supplied.
thanks,

A bit trifle to the experienced, this question probably is!
Say one is building a multi tier application:
web-front
business-logic
database
Going backwards:
1 - user clicks to get some info from the database.
2 - request is handled on the server
3 - business object is instantiated to process the request
4 - data access object is instantiated to retrieve the data
5 - user satisfied.
So the questions are:
1. Does 3 and 4 happen every time? The objects get instanciated? Or should the object be maintained in memory for the next call?
2. The data retrieved (dataset or should I say view) contains a lot more info (is complete in other words) before the business logic is applied. Shouldn't this dataset persisted in some way to be reused instead of making expensive calls to the database?
Now I may have the lines between the tiers wrong. So can someone elaborate?
A practical example would be nice (not code just pseudo).
