 Posted: Wed Nov 21, 2007 11:12 pm Post subject: [Delphi] - [CPP] conversion |
 |
|
In c ++,
the code:
| Code: | static const blahhh;
|
Blahh is defined as a static const.
But, how would i convert that to delphi?
I already know, you reverse it as in:
| Code: | | Blahh : static const |
but, static const isnt a type of var in delphi.

when I put
| Code: |
static const blahhh;
|
in a source file, the compiler warns me saying
| Code: |
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
|
That line doesn't make sense either, if it's a constant it should have some sort of value since you can't modify it later. If it does have a value and you've just omitted that for the post, when converted to delphi it should go under const, not var.
tl;dr integer

No, static const blahhh; doesn't specify as to what blahhh is to contain, which can't happen with a constant, as you must initiate a value upon their declaration(Because they can't be modified later in code.).
Should be C++, I'm not actually sure if you need to declare variable types in C++ for constants or if the preprocessor/compiler gets it for you.
| Code: | | final int blahhh = 10; |
Should be Java... just giving an example of another keyword here.
Delphi.

Uzeil, you do need to declare the type in C++:
| Code: | | static const int blehh= 0; |
in delphi, you can make a whole list of constants if you want, using the keyword only once (this is from memory, I haven't used delphi in a while)..
| Code: | const
blehh = 10;
blehh2 = 20; |

here it is:
| Code: | Const
[name]:[Type]=[value]
Ex:
Const
IAmAnInteger:integer=123;
IAmAString:String='Blah FTW~!';

In delphi, you do not need to specify the type of data for a constant like you do for C++.
This is legal in Delphi:
This is also legal in C++:
| Code: | | static const blahh = 10 |
Because 10 to the compiler is an integer. Therefore, you can omit the type.

You will not be able to use LoadLibrary with GetModuleHandle.
LoadLibrary returns HMODULE and GetModuleHandle takes in a LPCTSTR ( pointer to a constant string). Static doesn't exist in delphi as far as I know. Also, I always get an error when trying to assign a variable that is constant with a function that returns something in delphi. What I would do is
| Code: |
procedure TForm1.Button1Click(Sender: TObject);
var
something : HModule;
begin
something := GetModuleHandle('user32.dll');
...........
end;
end.
