As you seem to have access to the code, why not add a copy constructor or Clone method to ClassA?

Thanks for your response. That is a good suggestion, but in this particular case I am trying to avoid using that approach.
Much appreciated anyway

How can i transfer files from a specified location to my server using FTP.
|
|
|
|
|
Look at the MSDN Sample below:

|
|
|
|
|
I want to move all the files in the given directory path to server Using FTP.
|
|
|
|
|
Is this a C# question? If not then you just need to use the FTP commands to send the files. If you are trying to transfer through some code then you should take a look at the FtpWebRequest Class[^].
One of these days I'm going to think of a really clever signature.

Maybe you have to use a foreach loop and different threads to upload the stuff...
foreach(string file in Directory.GetFiles("C:\Temp\FtpUpload"))
{
FTPClass.UploadFile(file);
}

You'll either have to use a 3rd party grid control that supports it or develop you're own (not easy!). The DatGridView doesn't support it.
|
|
|
|
|
As I recall you can have drill-down functionality in a DataGridView, but I haven't tried that since 2005.
You probably don't want any grids at all. Grids are horrible.
If you are just presenting readonly data I recommend a TreeView for hierarchical data.
What is it you are trying to do?

I'm sure I saw there was a documentation regarding to enum usage.
I'm creating a game children that would involve a person that have enums of face, body, legs, feet, arms, hands. Each of those parts have unique values (i.e. face would have values of "round", "square", "oval").
I'm not quite sure on how to put those enums into "person" object.
Can anyone point out the documentation? Thanks!
(or should I use struct? or the other way?)

Something along the lines of:
public enum FaceType { Round , ... }
public enum FootType { Hairy , ... }
public class Person
{
public FaceType Face { get ; private set ; }
public FootType LeftFoot { get ; private set ; }
public FootType RightFoot { get ; private set ; }
...
}
might work, but I'm unsure it would be best -- for one thing adding new attributes, like new face types, might be more difficult than necessary.
You might consider have a config file or a database to store the types and values.

Hi,
I want to ask about MySqlParameter, when to use Add and when to use AddWithValue? because both seems to be working in every case I tried..

There is no difference in the end result, AddWithValue just shortens the parameter creation process. Use the one you are comfortable with.

You can use whichever you want, but I always use Add because IDataParameterCollection doesn't include AddWithValue.
|
|
|
|
|
use AddWithValue!
beacuse use a strongly type dataset functionality

Hi,
Maby this is simple for you, but for me is not.
I have this code:
int rezultat = 0;
try
{
if (sqlconn.State != ConnectionState.Open)
{
sqlconn.Open();
}
rezultat = (int)cmd.ExecuteScalar();
}
catch (Exception ex)
{
lblMesaje.Text = "Eroare: " + ex.Message.ToString();
}
finally
{
if (sqlconn.State != ConnectionState.Closed)
{
sqlconn.Close();
}
}
return rezultat;
Is just for inserting a new record in a table. Even if this throw an error "Specified cast is not valid." "rezultat=(int)cmd.ExecuteScalar();" - the code is executed and the row is inserted in the database, and the execution continues.
Why it continues?
Maby i don't understand the try catch finally yet 
Thank you!

The whole idea of try...catch blocks is to do exactly what you have done: catch an error, report it (or log it, or fix it) and let the software continue without crashing.
In your case, the exception is being thrown because the result returned by SQL is not an integer, and cannot be cast to an integer (it may be a DBNull, or a string for example - either put a breakpoint on the ExecuteScalar line and look at the return, or include the return value in your message to actually fix the problem). But the insert has been done by that time, so the row is in the DB already.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.
