Too bad 'free()' wasn't defined as returning a (void *). In that case, the code could have been written as:
flag = free(flag);
In case of any error other than a null pointer being passed in, free() could return the passed-in pointer.
Similar behavior could have been used with fclose() [return a (FILE*)] and other such functions that destroy the object whose pointer is passed to them. Oh well, only a few decades too late now.... Where's my time machine?

Discovered this gem in our code base (C#, but I guess that won't make much difference)...
if (transparent)
pdfDoc.HtmlOptions.HideBackground = true;
pdfDoc.HtmlOptions.HideBackground = true;

Well, if opaque then it's true, on the other hand, if transparent then it's so true.

I remember having to do something like that; repainting a dynamic form I think. It was easier to do the repaint twice based on a simple condition then to code a nasty, recursive, snaking, 683 if level method.
But I put a comment in to explain why.

No, nothing like that. Fortunately, we have a great Refactoring policy here that allowed me to simply fix the code. All is working fine, so I guess it was... well actually I've no idea.

Boss Type: ... Hmmm, do you think this will be a problem?
VB6'er*: Well, the thing is there's no way to get the ID of the rows you've just updated in SQL Server.
[Much later]
VB6'er: The input data must have been invalid - and then the import failed part way through updating twenty odd tables, but I don't know where. This is going to take me hours to sort out!
Boss Type: Well we need this sorted asap! I don't care if you have to work 'til midnight!

I'm curious, what does a VB6er look like these days?
I'm largely language agnostic
After a while they all bug me

My mirror says: Khaki shorts (with blindingly white legs sticking out of them), black T-shirt, a mostly gray absence of a haircut and glasses that were in fashion ten years ago or so...
Admittedly, I do a lot of C# these days and I come from a C background, but I do a lot of maintenance on my old VB6 code and even more VBScript. Not that I want to, but you know, there are these little creatures called customers that you sometimes have to take into account...

Normal... until the sun goes down...
The VB'ers then sprout large fangs, and multiple "insect like" legs. They then roam the streets looking for innocent software to devour.... ATM's, Petrol pumps, desktop PC's... nothing is safe...

I normaly hide in element 0 of an array. VB6er tend not to look there...

What was I thinking?
private static ProtoBlock LoadBlock(int x, int y, ByteReader stream, BlockHolder[,] blocks)
{
if (stream == null)
return RadishHelper.LoadBlockData(x, y, blocks, null);
return RadishHelper.LoadBlockData(x, y, blocks, stream);
}
Firstly, there is no need to check for null, as it is quite possible to pass null values on if it is a null.
Secondly, since the first point is true, this method only calls the other method, with no logic whatsoever.

Well, there is this curious item: BlockHolder[,]
|
|
|
|
|
That is one of the 2 ways to declare a multi-array, the other way is [][]
|
|
|
|
|
I believe there's a difference:
int x[][] will declare an array of arrays of integers, each of which may be initialised with its own number of elements (i.e. a jagged array).
int x[,] declares a 2-dimensional array, where the bounds of each dimension are specified when created and fixed.

I didn't say they were the same but yes you are right about both of them.
