I have a simple application in VC6.0 and ported it to .NET 2003.
I set "Use Managed Extensions" to Yes from the Project Properties->Configuration Properties->General because am using #using <mscorlib.dll>.
i get the foll error
Command line error D2016 : '/RTC1' and '/clr:initialappdomain' command-line
options are incompatible
i saw a lot of articles on this which suggested to do the foll to solve this error: i.e.
Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.
Click the C/C++ folder.
Click the Code Generation property page.
Modify one or both of the following properties: Basic Runtime Checks or Smaller Type Check
i tried changing options under Basic Runtime Checks but to no avail?
i still get the error?
How can I solve this command line error?
Pls help!
Sincerely
Giftsana

I do have following structure in VC++
struct Employee
{
int a;
char b;
float c;
};
i need to obtain the size of the above struct.
While using sizeof operator will it return the byte size(in this case 9) or padding will also be taken into account.
if so how the size can be obtained without padding
Thanks

The Almighty MSDN says:
"When the sizeof operator is applied to a class, struct, or union type, the result is the number of bytes in an object of that type, plus any padding added to align members on word boundaries."
If I am not wrong sizeof should return in your case:
10 bytes, because a word is 2 byte. But it might be even more, depending on your system and how the padding is done.
int = 4 bytes
char = 1 byte
float = 4 bytes
total = 9 bytes + padding to word boundaries (1 byte here)

it returns the size that the class/structure actually occupies in memory.
it can take 9 bytes (as you say) in minimum on a 32 bits machine ( (int = 4) + (char = 1) + (float = 4) ), but on a 64 bits system, your int will be 8 bits wide.
moreover, the compiler aligns the members on the larger member.... so, don't expect your struct to be 9 bytes wide.

how do you make a shared function?
In VB.NET I'd have done like this:
Public Shared Function f() As Integer
Think it's something like this:
public:<br />
int f()
but how do you make it shared?
|
|
|
|
|
As far as I know is the Shared keyword the equivalent to C#'s static keyword. Furthermore please note that the static keyword in VB is different to C#'s or C++/C one. However, static should be the way to go.

Hello everybody,
I have two classes, one in c# and one in c++. The c# class is derived from the c++ class. Now I want to create a new virtual member function. No problem. But the function should return a double value in an parameter.
I use VS2005.
c#
public override Status GetProgress (ref System.Double dVal)
{
...
}
What's the equivalent of the base class in c++ ?
virtual Status GetProgress (System::Double ^dVal) is wrong.
Does anybody know the solution?
|

Probably you're looking for a "tracking reference %".
As far as i know it should be in your case :
virtual Status GetProgress (System::Double^% dVal)
On the other hand an interior pointer might suit as well;
virtual Status GetProgress (interior_ptr<System::Double> dVal)

Hi Tobias,
thank you for the quick reply.
Using "System::Double^% dVal", I'm still getting an error message: no suitable method found to override. But "interior_ptr<system::double> dVal" works.
Now I'm checking, what it means... 
Thanks!!

// Assuming Status is a ref class
virtual Status^ GetProgress(System::Double% dVal) override
{
}

Hi George,
Thanks a lot! It works! Since I know it's a tracking reference, I found the description in the online help. Now I realized the meaning

how to create an algorithm?
|
|
|
|

Simple,
int algorithm (int i) { return i; }
"Programming today is a race between software engineers striving to build bigger and
better idiot-proof programs, and the Universe trying to produce bigger and better idiots.

this is not exactly an algorithm, as it refers to a programming language...
but as the question was a bit stupid, i second you in your answer 
|
|
|
|
|
your question doesn't mean anything.
take in consideration this :
what do you want to achieve ?
what main steps do you have to go through ?
what technologies will you use ?
|
|
|
|
|
>your question doesn't mean anything.
If your a programmer it should!
An algorithm is just a list of
instructions detailing how to
do something. Could be making
a peanut butter and jelly
sandwich.

|

man, i know what an algorithm is
but still the question didn't mean anything...
what sort of algorithm was want ?
printing ?
3D rendering ?
Arccosine calculation ?

I didn't write the question nor

Is it possible that foxylady is referring to an STL Algorithm?
|
|
|
|
|
wow ehhmm, i really don't know, but now you say it, maybe !!
but 1) the question is really not clear, and 2) it is not the good forum for that, so i was far from thinking to STL algorithm...

I'm an infant when it comes to C++.
Can anybody help me to access a text file which has a comma that separates every item and after which put that file into an array which can be access later.
The problem is the items in a file are in this manner, each line:
char,int,int,int,long int,long int........
char,int,int,int,long int,long int........
char,int,int,int,long int,long int........
char,int,int,int,long int,long int........
........
.............
.........
......
upto 57-60 lines
Do i have to separate the char and int and long int and put it in different array?
Or put the items in a struct....
|
|
|
|
|
you can have struct array or array in struct.
|

Thanks a lot Saksida, i'll use struct array. you give me the hint that uncovers a mile area.
i'm currently studying how to do that.... at this website..
http://wps.aw.com/aw_savitch_abscpp_2s/0,10408,1982372-,00.html
there are few problems: this is the overview of my project, i mean a chunk of my project..
Actual items in the file M637.VIN
M2,2,1,15,55342,55662,55982,56302
A,4,1,15,58856,59176,59496,59816
P,5,1,15,55327,55647,55967
B,7,1,15,55310,55630,55950,56270
4B,8,2,15,27769,25530
General format:
char_val,int_val1,int_val2,int_val3,longint_val1
How am I suppose to say this…..
char_val = string or character
int_val1 = integer
int_val2 = integer
int_val3 = integer
longint_val(n) = an array of long integers
is it possible to store these stuff in a struct or an array of some sort? Coz i need int_val1 and int_val2 as a reference to an output port.
in line 1 "M2,2,1,15, 55342,55662,55982,56302" , i need to access the extracted input ‘2’ and ‘1’ coz it corresponds to an output port2 and port1.
on the other hand, char_val must be taken into account coz it serves as a reference to longint_val(n).
