I have a solution with a managed C++ project, and a C# project which references the C++ project.
My C++ project contains the following:
struct AAA { ... };
typedef public enum BBB { ... };
public delegate void CallbackDelegate(AAA * a, BBB b);
class SomeClass
{
...
static void RegisterCallback(CallbackDelegate^ callback);
...
}My C# project is supposed to use RegisterCallback().
I can't use the CallbackDelegate in my C# project though, because it contains a pointer.
So I've declared the following in C# hoping that .NET would do the conversions for me  :
[StructLayout(LayoutKind.Sequential)]
public struct AAA { ... }
public enum BBB: int { ... }
public delegate void CallbackDelegate(AAA a, BBB b);However, now I can't send my CallbackDelegate as a parameter to RegisterCallback() because it's not the same signature.
I'm new to all of this C++.NET s**t, so I don't really know how to use it in C#.
Could anyone point me in the right direction?
Thanks in advance,
Shy.

Couldn't you just create an unsafe delegate in C#?

Hi I just wanted to know the proper way of updating a DataRow.
If I have a DataTable say locDTable which already has rows populated through
Iterate<br />
{<br />
DataRow locDRow = locDTable.NewRow();<br />
locDTable.Rows.Add(locDRow);<br />
}
How do I access (and modify a particular column entry for a particular row?
The way I would do it something like:
locDTable.Rows[rowIndex][colIndex] = newValue;
Is this the proper way?
Thank you in advance!

Hi
Maybe, instead of access to the column by an index you can use strings constants to access to columns. It seems more elegant and if you change the structure of the table the acces to the previous column doesn't change.
To access to a particular row the only way is by an index.

I agree 100% with the constants approach for column names, we do that all the time here and has paid of on numerous occasions. We also do it for the table names.
It decouples you from Database especially for column name changes (just change constant literal) as well as makes the code much more readable.

Hi All,
Facing a peculiar problem.
I have MajicAjax implemented in my web page & the code runs perfect(My M/c's OS - Win 2000 Professional),whereas on the Tester's M/C it gives me script library '/AjaxCallObject.js' error on loading the same page(Tester's OS - Win XP). Furthermore, this problem persists only in some selective M/c's running on Win XP. Found some useful sites & tried the same but with no success.
Can anyone plz help asap...
Thanks in advance.

I'm writing a program in C# 2005 Express and one of its functions is to scan the hard drives of the computer for specific files.
However, due to the diversity of the machines this program will run on, I cannot guarantee the drive letters for each hard drive.
Is there any way I can find the available drives so I can limit and speed up my scan?
I know I could use HKLM>Software>Microsoft>Windows>CurrentVersion>Explorer>MountPoints2
to find what drives are there.... but that doesn't distinguish between drive types (Hard Drive, Floppy Drie, CD Drive).
And help would be greatly appreciated.

Ha.
Thanks.
I can use that with System.IO.DriveInfo to get what I need.
That's what I love about CodeProject... response within a half hour.

sanjit, there are so many other ways to memorize your email id. This looks really awkward. Please remove them from your signature.
