Delphi's with..do block in C?

[BobbaFet]

Is there an equivalent for Delphi's with..do block in C?

if not Programming = 'Severe Migraine' then
                       ShowMessage('Eureka!');

I suspect the while ... do or do ... while loops may work. It's been a long time since I've programmed in Pascal.

with with do blocks you can do stuff like:

[b]with[/b] ObjectX [b]do[/b]
  [b]begin[/b]
  property1 := this;
  property2 := that;
  property3 := False;
  [b]end;[/b]

Basically, it allows you to access the same object without having to redeclare the object over and over again.

In C++ it's more like:

ObjectX->property1 = this;
ObjectX->property2 = that;
ObjectX->property3 = False;

No with...do.

Yes, in Delphi you would normally use:

ObjectX.Property1 := this;
ObjectX.Property1 := that;
ObjectX.Property1 := False;

But when you need to set a lot of properties and/or use a lot of methods you can use with..do blocks to shorten it. But from what I understand there is no such thing in Cpp?

AFAIK, no, there is not anything like that in C++, at least in the Builder versions I've used.

If the name of your object is long:
place

#define MyVery_very_and_very_long_object_name Short

Short->property1 = this;
Short->property2 = that;

 

[luckieluc]

An look alike could be:

#define M(T) Memo_c->Lines->Append(T)

M("Some ...");
...
M("Some....");

#undef M

Ok, ty all for your imput! Too bad there isn't, it really helps with code readability, the shortening of names is a good alternative and I will use that instead.

No needs in with-like construct in C++. You can access class/structure members directly in member functions. To access public data members outside their class is a bad (at least ancient) programming style (so Pascal with construct is simply yet another rudiment of old good "structured programming" ...
