While you already know the answer, you might be interested in knowing how you could have discovered it yourself. Try this:
...
char buf[2048];
int x;
while ((x = fread(buf, sizeof(char), 2048, fin)) == 2048)
{
cout << "Read " << x << " bytes" << endl;
fwrite(buf,sizeof(char),x,fout);
}
if (x > 0)
{
cout << "Read " << x << " bytes" << endl;
fwrite(buf, sizeof(char), x, fout);
}With my 160KB test file, it produced:
Read 2048 bytes
Read 2048 bytes
Read 304 bytes
I simply opened up the source file and looked at offset 4400 which was indeed the ASCII 26 character. BTW, you need to swap the second and third parameters in the calls to fread() and fwrite(). Currently, you are telling fread() to read 1 character whose size is 2048, when instead you should be reading 2048 characters whose size is 1.

Declare your variable with extern keyword in stdafx.h the global header file of project and declare same variable in .cpp where you want to use that variable file (remember .cpp file)

Could you throw more light on this topic

hi
I habe problem in setting one value:
I have created the ATL component int that i have one metohd which gives call to first dialogbox and i am setting one value which will be return from add property method.

below is my code the whole program is for prompting user to enter 10 nos. b/w 20 to 100 it will while is there to check wheter the user entr the corect number or not, it will also check that the entered number is unique and was not previously entered by the user. at end of program simply it will display the non dublicate nos. whole program is correct but at end it is not displaying correct result . plz check the code n tell me wherz my mistake.
#include<conio.h>
#include<iostream.h>
#include<stdio.h>
main()
{
int nTmp,j;
//declares variable bflag th be of type bool & intializes bflag to false
//bool is a data type whose value may be false or true
bool bFlag=false;
int a[10];
cout<<"entr 10 numbers b/w 20 and 100"<<endl;
="" for(int="" i="0;i<10;i++)" {="" cout<<"enter="" value"<<endl;
="" cin="">>nTmp;
while(!bFlag)
{
////Here we check first Condition
// no between 20 and 100
while((nTmp<20)||(nTmp>100))
{
cout<<"enter no b/w 20 and 100"<<endl;
="" cin="">>nTmp;
}
j=0;
while(j<=i)
{
if(a[j++]==nTmp)
{
bFlag=false;
}
bFlag=true;
}
if(bFlag==true)
{
//save variable
a[i]=nTmp;
}
}
//again make it false
bFlag=false;
}

you forget to insert a Loop here i.e.
for(i=0;i<10;i++)
cout<<" the non dublicate nos are "<<a[i]<<endl;

Here is full sourcecode i created for you because you are showing efforts, but i still insist that you read your Text Book.
#include<iostream.h>
void main()
{
int nTmp,j;
bool bFlag=false;
int a[10];
for(int i=0;i<10;i++)
{
cin>>nTmp;
while(!bFlag)
{
while((nTmp<20)||(nTmp>100))
{
cout<<"enter no b/w 20 and 100"<<endl;
cin>>nTmp;
}
j=0;
while(j<=i)
{
if(a[j++]==nTmp)
{
bFlag=false;
cout<<"You already entered this Number!enter unique no "<<endl;
cin>>nTmp;
break;
}
bFlag=true;
}
if(bFlag==true)
{
a[i]=nTmp;
}
}
bFlag=false;
}
for(i=0;i<10;i++)
cout<<a[i]<<endl;
}

the same code i tried.. my prob is that i need to print only dat numbers that r not repeated.like if i entered 50, 60, 80, 90, 99, 56, 50,98, 45, 99 so here 50 and 99 are reapeating so in the output ony 8 nos that r 50, 60, 80, 90, 99, 56, 98, 45 such that the nos that r repeating should not be displayed as u observe it in output.this is not diaplyind the ouput which i want.
for(i=0;i<10;i++)
cout<<" the non dublicate nos are "<

Is there anyway that I can cast a graphics path to a bitmap?
Im trying to make a freehand sketch program using John Buettner's example, the problem is that when changing the pen color and width it effects everything drawn into that path previously. I figured the best way to do it would be casting the graphicspath into bitmap format on mouseup and then resetting the graphicspath though after playing around with it quite a bit im still not sure how to go about it.
Any help appreciated thanks.

Why not just save the pen size and colour information along side every path?

OnKeyDown(UINT nChar, ...)
{
char lschar = char(nChar);
if (lschar=='A') AfxMessageBox("Key A is pressed");
}
In the same way, how to test when key: UPARROW, LEFTARROW, RIGHTARROW, DOWNARROW, NumPad-, NumPad+ is pressed.
thanks for help me!
don't stop me now!!!

I use an easy method it seems to work.
onkeydown(UINT nChar....)
{
CString string;
string.Format("%d",nChar);
AfxMessageBox(string);
}
This func. tells you the code whic you press.
|
|
|
|
|
switch (nChar)
{
case VK_UP:
// up arrow
break;
case VK_LEFT:
// left arrow
break;
case VK_RIGHT:
// right arrow
break;
case VK_DOWN:
// down arrow
.
.
.

I thought 'mind' comes as default and free with every package. Is it removed nowadays coz of complaints from 3rd party mind builders ?

change this to
onkeydown(UINT nChar, ...)
{
char lschar = char(nChar);
if (lschar==VK_UP) AfxMessageBox("Key UP is pressed");
}
for rest you can make yourself here is Virtual keycode for them VK_RIGHT VK_DOWN VK_LEFT VK_ADD VK_SUBTRACT

I'm writing a file parser. It's really pretty simple. Here's a sample file:
B C 25
A D 36
D E 63
B A 48
C D 30
D B 52
E C 30
C P 30
P Q 52
Q X 51
X Z 70
Z X 20
X Q 20
*
My question is this: Notice that blank line in the middle? How, in C++ using ifstream, can I detect when the parser reaches a blank line such as that one, but still be able to continue parsing?
Thanks for any help!
