I want Instructions() to make an array and i am not sure how should I do it..
i posted just the example showing the meaning the problem, so here is the full code:

maybe now it will be easier to understand..

You're creating the arrays fine but not deleting them
int* instr=new int[dydis];
...
delete[] instr;
I'm not sure what you are trying to do in your code.
You use new and delete so the problem is not with array creation but is with the logic of the
code.
You have to eventually call delete on any of the pointers returned by new. Those pointers could
be stored in variables, an array, etc.

I knew that we can not create multi dimensional array with new. But in Navigating C++ and Object-Oriented Design book, it writes:
Type *pname = new Type[size]; <br />
Type (*pname)[size2][sizeN] = new Type[size1][size2][sizeN];
for example:
A (*pu)[1] = new A[1][1];
delete [] pu;
Is this example code really means that this is dynamic array? Or something different?
Assume that we create N-size array, Is it always enough to write delete[]?
Thanks.

Hi.
With Visual Studio 2005 and .NET it's too easy to consume and create a Web Service, but what about using MFC?. I got a MFC application, (a dialog based application), and I need to consume a Web Service, (created with Visual Studio 2005 in ASP.NET), how could I do that?. I know, SOAP is the answer, but I need a guide, (maybe there's an article already writen, or something like that).
Thank you and regards.
Demian.

hey everyone. can anyone help me with setting up a texture in visual studio.
heres my code just in case thats the reason why my texture isnt showing up.
thanks everyone!!!

Dear all
we have a program(binary code) . We want to make it to have high process and thread priority.
is there any function or way that we can do this from an application which we write to make that program have high priority?
Also we have one Device driver which has one kernel mode thread in it.
Is there any way to change the priority of system thread of that driver?
we have only .sys version of that driver.
Regards
Monhi

Hi,
Does anybody know a tool for Visual Studio .Net, for programming in C++, that when changing a class / data member / function name - it can automatically rename all references to the class / member?
Thanks!

BOOL bValue;<br />
<br />
if (bValue)<br />
{<br />
bValue = FALSE;<br />
}<br />
else<br />
{<br />
bValue = TRUE;<br />
}
If write this code to InterLocked functions, how to write?
if (InterlockedExchange(&bValue, TRUE) = TRUE))<br />
{<br />
InterlockedExchange(&bValue, FALSE);<br />
}
Right?
Thanks.

Currently, i am translating my VC++ 6.0 program into C++ program.
in my old VC++ program, i wrote an struct array into a file using
<br />
for(i = 0; i < struct_array_size; i++)<br />
{<br />
CFile::Write(&struct_address, sizeof(struct))<br />
}<br />
the struct is defined as
<br />
struct S{<br />
string Str;<br />
int Value;<br />
}<br />
Now, i wonder if there is an equivelent in standard C++ for CFile::Write().
Thanks,

All the same file I/O methods are still there. Are you trying to not use MFC?
The stdio functions (fopen, fread, fwrite, etc.)
The fstream classes
CAtlFile
CFile and derived
Windows APIs
etc.
Also, writing a string object like that - I don't think that will work (it may write but reading
it back in, I don't think so). It will write the object bytes but not the string contents.

Mark Salsbery,
thanks,
Yes, I am avoiding to use MFC classes.
Would you please be more detialed on how to use fstream class to implement my purpose.
Yes, i actually had problem with string item in the struct. Actually, I used char Name[20]. However, the length of the contents is varying. 20 is the max. length of the Name attribute of objects. Hence, memory was wasted by objects with a Name less than 20 characters. How to solve this problem.
Actually, I need a function in pure C++ framework to write/read the struct as a whole just as with CFile::Write() in VC.
