Well, then what are you asking?
|
|
|
|
|
if primitives are objects (because everything are) then they should be passed by reference. well i'm after the contradiction, i know for a fact that they are passed by value. (i think Christian Graus' answered it).
----------------------------------------------------------
this is a sig++

Yes, everything boils down to an object, but remember those primative types (Int32, Int16, etc) actually inherit from ValueType which itself inherits from Object.
The point here I think you're trying to grasp is that the runtime treats things that inherit from ValueType different from things that don't
|

If it inherits from System.Object it is an object.
The enlightened answer to why this doesn't contradict anything is buried in Computer Science course work. But if I recall correctly a short answer would be the value of the pointers to objects are passed and the compiler knows based on the type to dereference the pointer to yield the object data from the heap. If you could directly alter the stack in C# you would be able to change the value pushed on the stack for the object without affecting the referenced in the calling code because it would just be a value reference.
Need software developed? Offering C# development all over the United States, ERL GLOBAL, Inc is the only call you will have to make.
If you don't ask questions the answers won't stand in your way.

hi,
I am having 3-4 records in my database. I written code to display records from the database to datagridview. I use cellclick event for editing the records.
Now datagridview has by default sorting. But Now when ever I click on the column header it will display error. Sorting is not happening becos of the cellclick event.
What can I do?
Thanks

You're trying to display a message and the user the service runs under, can't do that. Vista is just telling you.

Don't do that either. You can't circumvent the windows UAC, there is a reason for that.

Mono is a framework tho, it's not an IDE, you'll have to find an IDE that supports it ( I am sure there is one )

Funny, it's not urgent to me at all.

You're not too bright, are you ?
1 - advertising your email is a good way to get spam
2 - if you registered on CP with this email, you'd get email replies when people reply
3 - why should we email you if you're not interested enough in this community to watch for replies here
4 - no-one is going to mail you code
I just checked, and google would love to help you download sample code to do this. Why didn't you try to find your own solution before asking us to do it for you ?

OK - then choose an easier task. If this is homework, talk to your teacher. If this is paid work then you are a disgrace.,

I found several examples of source code. If you could not understand them, you won't understand anything you get here.

I love the crappy attempt to boost your ego in attempt to get code.
"That's why I contact a bright man like you", is that little compliment supposed to get him code or something?

Hi all,
I have a C# desktop application and I am using MS-Access database.
I am using below code for update operation.
string SqlString = "UPDATE table_name SET Bdate = @Bdate WHERE SrNo = @SrNo";
OledbCmd = new OleDbCommand(SqlString, OleDbConn);
OledbCmd.Parameters.AddWithValue("@SrNo", intSrNo);
OledbCmd.Parameters.AddWithValue("@Bdate", DateTime.Now.ToString());
Same approach is used for Insert operation also.
All working fine...
But I have read in one article that, DateTime should be enclosed withing single quote or #, when you are working with MS-Access. Right now, my code is working fine.
Please, explain me if there is any difference between the approach I am using and the approach that I have read..
Thanks,
Regards,
-SIFAR.

What is the field type of "@Bdate" in the database ?
# and quote are date delimiters in MS-Access. The older versions only supported # but the newer version support quotes as well.
|
|
|
|
|
If Bdate is a date then don't call ToSTring() when setting the parameter
OledbCmd.Parameters.AddWithValue("@Bdate", DateTime.Now.ToString());
