This is not correct, for a start struct_ptr has not been initialised to point to anything. I always try compiling my code suggestions before posting here.

I did not understand. You are trying to get a handle to a specific icon ?
What does this have to do with the computer name ?

You need two functions:

Those are not functions that you call directly. You implement them so that the framework can call them as needed. See Technical Note 30 for more.

In addition to David Crow's answer, there are much more things going on than just calling the functions.

You also have OnPreparePrinting , OnPrepareDC and many other things working in a depper part, that you don't code directly.

If you need to restart your machine in order to make it working another time, one cause could be a bad use of CDC, so it gets problems and it doesn't work until the OS is started another time.

I strongly recommend you to go step by step in printing, there is a lot of things to consider and that can give problems. Here in codeproject you can find some very good articles about printing, take a look on them.

With the information you have given is almost impossible to help you.

you should give more details, debugging your application and seeing what happens when it hangs, putting a bit of code...

#define how to use with is code ?

krish_kumar30-Dec-09 15:56

30-Dec-09 15:56

int main()
{
printf("Enter 0 or 1 :");
scanf("%d",&i_choice);

if ( i_choice ==0 )
for( ;i_count_1 < i_number;)
{-------
------
}

if (choice == 1)
for( ;i <= i_number;)
{-------
------
}

Here I raed a user input ( 0 or 1)
So as per i/p I've to change the condition in my for loop.
if choice ==1 the condition must be (i <= i_number)
if choice == 0 the condition must be (i_count_1 < i_number)

I don't know how to use #define with this program.

anybody can help me....

You don't need #define in your code sample, but you need a switch(i_choice).

krish_kumar30-Dec-09 16:30

30-Dec-09 16:30

here I wanna reduce the code size....

swith(i_choice) {

case 0 :
for (.. ; condition 1 ; ..)
{

}
break;
case 1 :
for (.. ; condition 2 ; ..)
{

}
break;

}

So the code will come twise ; except the conditions in for loop all other statements are same for case 1 and 0. That's why I tried for a #define Macro. ????

with regards
Krish

Then could you show the complete code (I mean those ... portions)? I will figure out a solution for you.

Which would be totally wrong. The #define directive is handled by the preprocessor before the compile phase. You don't know the value of i_choice until the code is running. See the problem?

30-Dec-09 18:17

Okkk... I realize I can't use a #define here....

But my code is repeating twice ...I wanna avoid that....
Except condition the other statements are same for both...

Here is my code

printf("\n U wanna find prime nos up to N(press 1)
or N prime nos (press 0 ");
scanf("%d",&i_choice);

switch(i_choice) {

case 0 :
for (i = 1, i_count = 0; i_count_1 < i_number; i++ ) {
for (j = 1,i_count = 0; j <= i ; j++) {
if ((i % j) == 0)
++i_count;
}
if (i_count <= 2) {
printf("\t %d \n",i);
i_count_1++;
}
}
break;

case 1 :
for (i = 1, i_count = 0 ; i <= i_number; i++ ) {
for (j = 1, i_count = 0; j <= i ; j++) {
if( (i % j)==0 )
++i_count;
}
if (i_count <= 2) {
printf("\t %d \n",i);
i_count_1++;
}
}
}
}

I would suggest you to re-design your code architecture. See the sample code below.

#include <iostream>

int GetNextPrime(int iStartNum)
{
	int i, j;
	int i_count;
	for(i = iStartNum; ; i++) {
		for(j = 1, i_count = 0; j <= i ; j++) {
			if( (i % j) == 0 )
				++i_count;
		}
		if(i_count <= 2) {
			return i;
		}
	}
	return 0;
}

void main()
{
	int i_choice;
	int i_count;
	int i_count_1 = 0;
	int i_number = 10;
	int i, j;
	int iValNow;
	int count;

	printf("Find prime nos up to %d (press 1), or %d prime nos (press 0) ", i_number, i_number);
	scanf("%d", &i_choice);


	// ---------------------------------------------------------
	printf("\n My version: \n");
	switch(i_choice)
	{
	case 0 :	// N count.
		for(i = 0, iValNow = i, count = 0; count < i_number; i++, count++) {
			iValNow = GetNextPrime(iValNow +1);
			printf("\t %d \n", iValNow);			
		}
		break;
	case 1 :	// up to N.
		for(iValNow = 0; ; ) {
			iValNow = GetNextPrime(iValNow +1);
			if(iValNow > i_number) {
				break;
			}
			printf("\t %d \n", iValNow);
		}
		break;
	}

	// ---------------------------------------------------------
	printf("\n Your version: \n");

	switch(i_choice)
	{
	case 0 :	// N count.
		for(i = 1, i_count = 0; i_count_1 < i_number; i++ ) {
			for(j = 1,i_count = 0; j <= i ; j++) {
				if( (i % j) == 0 )
					++i_count;
			}
			if(i_count <= 2) {
				printf("\t %d \n",i);
				i_count_1++;
			}
		}
		break;

	case 1 :	// up to N.
		for(i = 1, i_count = 0 ; i <= i_number; i++ ) {
			for(j = 1, i_count = 0; j <= i ; j++) {
				if( (i % j) == 0 )
					++i_count;
			}
			if(i_count <= 2) {
				printf("\t %d \n",i);
				i_count_1++;
			}
		}
	}
}
