Re: Windows Console Applications

Consoles Applications are character mode ones (like the command prompt), see
http://msdn2.microsoft.com/en-us/library/ms682055.aspx[^]

BTW often the standard C (or C++) Run-Time I/O library is used (instead of Console Functions) to provide I/O to such applications.

dear all

#include <iostream>
using std::cout;
using std::endl;

void printArray(double [][4]);

int main()
{
double a[3][4] = {{0.3,0.4,0.5,0.6},{0.1,0.7,0.8,0.9},{0.11,0.12,0.13,0.14}};

printArray(a);

return 0;
}

void printArray(double a[][4])
{
for (int i = 1; i<=3; i++)
{
for (int j = 1; j j<=4; j++)
cout << a[i][j] << " ";
cout << endl;
}
}

why the result is changed in the end of one row?

thanks

Hey man, C++ arrays are 0-based

Hey man, C++ arrays (like C ones) are 0-based, for instance

int a[3]; // declare an array with three elements
a[0] = 5; // set first element
a[1] = 2; // set second element
a[2] = 4; // set third element
a[3] = 12 // set fourth... OOOPS this is a MISTAKE: out of array upper bound!

hence check your iteration limits.

Hi all,
can I create deep folder hierarchy which is exceeding 260 characters on windows 2003 server?
Is there any way to do this?

260 characters for the whole path, or just one of the folders in the path? Have you looked at SHCreateDirectoryEx()?

In the whole path. like c:\qbc\def\jhi\....

I looked into SHCreateDirectory. I found a limit of 248 chars.

But When I look CreateDirectory [naming a file link ] I got confused.

SHCreateDirectoryEx() has a limit of MAX_PATH characters, but it will create folders recursively.

CreateDirectoryEx() has a limit of 32,000 characters when Unicode is used.

Thanks for the great information. I have created a directory hierarchy Smile | :)

.
Now I have problem is accessing it programmatically. I tried using CreateFile but it fails.

You may want to use make sure you're using the Unicode version of CreateFile and make sure the path specification starts with \\?\.

I recommend against using such long path names because of very limited tool support when the path name gets beyond MAX_PATH length. Shorten the directory names where possible and flatten your directory structure as much as possible to stay under the MAX_PATH limit.

Hello All,

I am working on a application with VS 2005, in which so many calculation is happaning and also graphics is drawing.

i am having some statement in which values are coming as follows

double aa1 = 69444400000.0;
double aa3 = 694.0;
double aa4 = aa1 + aa3;

if i performed these statement before graphics is drawing than they calculating correctlly

the values of aa4 is 69444400694.0
but after drawing the value is : 69444403200.0
while value shold be 69444400694.0

plese give some idea...

thanks
Banks

Could you make a clone of the variable for backup, and then add some breakpoints to trace the value of aa4?!

double dTemp = aa4;

thanks for reply,

even i am using hardcoded vaues as i write in my previous post.

than also VS is not able to clculate or right value.

when i calculate by these variables in immediate window than it shows right value.

thanks

I know you hard-coded such values, but what about the graphics you're doing?
What kind of memory accesses are you doing?
How can we help if you don't post the code?

Your drawing logic may be altering the value. Try declaring aa4 as a const double. But, some of us may be providing you an appropriate solution if you post some relevant code.
