We have a file where the method list does not list all methods. I have investigated and distilled a test case for you here to show the problem.

The following piece of code will only make Test::Test1() show in the method list. All methods after this will not be shown.


bool Test::Test1()
{
	bool bTest = true;
#if 0
	int iTest = 0;
	for(iTest = 0; iTest < 10; iTest++) {
		bTest = true;
#endif
//	}

	return bTest;
}

void Test::Test2()
{
}

The offending code is the for loop, and if it is commented out Test::Test2() will show up in the method list:


bool Test::Test1()
{
	bool bTest = true;
#if 0
	int iTest = 0;
//	for(iTest = 0; iTest < 10; iTest++) {
		bTest = true;
#endif
//	}

	return bTest;
}

void Test::Test2()
{
}

Also if the ending braces are surrounded by an #if 0 instead, the Test::Test2() function will also show up in the method list:


bool Test::Test1()
{
	bool bTest = true;
#if 0
	int iTest = 0;
	for(iTest = 0; iTest < 10; iTest++) {
		bTest = true;
#endif
#if 0
	}
#endif

	return bTest;
}

void Test::Test2()
{
}

I hope this is a bug that can be fixed, since the method list is my primary way of navigating large files.

Regards,
Rasmus Sigsgaard

I am seeing the same effect here. Thank you for the clear description.

case=3498

The #if 0 mixed with // is actually confusing the problem. The problem is the unmatched curly brackets inside the function. You can simplify the code down to:

static void listedFunction1()
{
#if 0
	{
		{
#endif
}

static void invisibleFunction1()		{ }

which is what you have, since when you commented out the closing bracket. For now I would suggest selecting code and using * or / to comment out the code, so that you have commented out both the opening and closing brackets.

Thank you. I have made a temporary fix to the largest "broken" files I use the most, but since we have a lot of people working on the same code I'm hoping that VAX will be able to handle this kind of situation.
