Thanks! It works using a std::vector<char>, but I wasn't sure if it was correct to use the same &junk[0] method for std::string.
|

Yep, vector and string are the two STL containers with guaranteed contiguous memory.
|
|
|
|
|
Actually, Neither string or vector guarantee contiguous memory today. There is a proposal in front of the committee to alter the standard to require contiguous memory for vector, but not for string.
Having said that, it's highly unlikely that anyone will create a string implementation that doesn't use contiguous memory, at least on Win32.

I'm writing a MDI application with a toolbar in a child window. I want to chnge the toolbar from flat to non-flat buttons (and back) programatically.
I've already got a function in the CChildFrame class that responds to an message, but everything I try results in failure (in one form or another).
Does anyone know what the secret is?

Hi John,
I just tried with ModifyStyle(TBSTYLE_FLAT, 0) (and vice-versa) and Invalidate() and it seems to work. It's a very simple project though ...
From where are you trying to change the toolbar? (I did it in the MDI child frame)
Well, I think we all need more details to help

That was exactly what I needed. Thanks buddy.
I was over-engineering my own attempt at a solution, and was so far into the forest, I couldn't see the trees.

I can't figure out how to control the color of text drawn with CDC::TextOut. CFont or LOGFONT don't seem to have a color attribute, and none of the other crazy things I tried worked. Ideas?
thanks,
Jake

CDC::SetTextColor(clr);

A long is 32bits.
so try 2^31 for a long (1 bit for sign) and 2^32 for an unsigned long
+-2147483648 and 4294967296
there are defined for these. Look for MAX_LONG, MAX_FLOAT etc.
|
|
|
|
|
from -2147483648 to 2147483648.
The LONG is a 32-bit signed integer!!!
Cheers!!!

What this 'xor'?
How do use in this in vc++
|
|
|
|
|
True xor True => False
True xor False => True
False xor True => True
False xor False => False
For use it you need to use the ^ macro.
^ == Xor
Cheers
Carlos Antollini.
|
|
|
|
|
so:
^x;
or so:
x^;
or another ?
|
|
|
|
|
XOR is a binary operator.
z = x ^ y;
if x = 00101101b
and y = 01110111b
then z = 01011010b
Hope this helps.

CSrting str;
I want that str would contain some variables in its string
for example so:
str = (" the price is %d, the nameis: %s", x,s);
|
|
|
|
|
Use.
CString::Format();
Is like sprinf();
CString str = _T("");
int iVal = 10;
Cstring strName = _T("Carlos");
str.Format("The price is %d, the name is %s", iVal, strName);
Cheers!!!

The size of an integral type is entirely compiler-dependent (well, except for char which is always 1 byte). In MSVC, an int is 4 bytes.

The MDSN say:
The sizeof Operator
The sizeof operator gives the amount of storage, in bytes, required to store an object of the type of the operand. This operator allows you to avoid specifying machine-dependent data sizes in your programs.

If you don't believe, please make this.
int n = sizeof(int);
n will be equal to 4 like Michael Dunn Said.
