I have an existing VC6 C++ application that I'm using to post http calls into a .NET web service. One of the methods on this web service returns a DataSet object which has pretty complicated XML; including base64 encoded binary blob fields. Has anyone attempted to create a C++ class that can emulate the C# DataSet class; and be able to parse that XML and provide accessors to the rows and column values? I am going to have to do this, but thought I would first see if there was any exising code I could make use of rather than re-inventing that wheel.
Thanks if anyone has a starter block of code they don't mind sharing.

Is there any utility which converts VC++ code to C# code. I do not expect all conversions basic conversion will do such as class, property, method migration.
Thanks

i believe no... you must rewrite all the VC++ Code into C#...
in fact you must redesign the code to get the best performance in C#...

What is the best was to get the modified date/time of a file ?
I'm using VC++6.0.
Thanks.

How about GetFileAttributesEx()?

or CFile::GetStatus() or _stat() or GetFileTime().

Thanks Ravi,
I'd seen GetFileTime on VC6 but it only talked about WinCE !
I checked again at home where I have .NET2002 after your reply and it listed NT/2000/XP too. Odd

I have the following problem :
I have written a MDI Application opening and reading files of type *.myapp
I have made a file association with my application and when a user clicks a file with the extension *.myapp my application starts but does not load the file.
I know I have to read the parameters the shell passes to my program, but I do not know how. And I do not know for which event I should write a handler.

Did you use AppWizard for this?

In visual studio .net ver 2003 in reguards to c++ my multiplication is messed up. I get a result of 0 when I try and multiply the following. What's wrong?
#include "stdafx.h"
#using <mscorlib.dll>
#include "math.h"
using namespace System;
int _tmain()
{
__int64 p;
p= 16 * 268435456;
Console::WriteLine(p);
return 0;
}

I assume that the WriteLine() method supports a __int64 type. What is the largest value (e.g., 231) that you can successfully send to WriteLine()?

The number I am multipling with 16 is the highest number for the output.
|
|
|
|
|
If 228 is the highest number for the output, what does outputting 228 + 1 produce? If that does not work, I would expect 232 to fail as well. Yes?

The highest number I can multiply it to is 7 after that I get the error message:
warning C4307: '*' : integral constant overflow

That indicates that you are running into a signed/unsigned problem. What does this yield:
p = 8U * 268435456U;

What about:
unsigned __int64 p;
p = 16U * 268435456U;

The compiler is telling you exactly what's wrong "integral constant overflow". That expression overflows the capacity of an int. You need to specify that the constants are 64-bit ints:
p = 16I64 * 268435456I64;

Thanks Mike. I was aware of L and U but did not know about the I64 modifier.

That worked great. However is there a way I can use exponents with the 64-bit int's?

I'm sure there is something simple and obvious that I am missing here, maybe somebody can help me?
I have a toolbar that gets initialized from a toolbar resource (one big bitmap with all images in it).
The toolbar is customizable (using standard dialog), so that when the dialog is displayed, you get a list of all the buttons available on the left, and a list of all the buttons currently on the toolbar on the right.
The buttons on the left and right together are all of the buttons available in the toolbar resource bitmap.
In some cases, I would like to exclude some buttons in the toolbar resource bitmap from being displayed as available (i.e. remove them from the left list).
When the list is populated, you get messages that let you say whether the button is available, but the first time you say no, it stops asking about the remaining buttons.
Like I said, there must be something simple I am missing.
Thanks for you help!

Wouldn't it be easier to just enable/diasble the buttons? If not, then you'll probably need to create multiple toolbars (one for each situation).
