Hi all. I'm implementing a macro that I need to have take multiple parameters.
Let's say I'm implementing a printf macro. (I know. I know. Just run with me for the example.  )
#define PRINT(str,...) printf(str,__VAR_ARGS__);
Well, obviously, someone could invoke the macro thusly:
PRINT("My name is %s and I am %i years old.", szName, iAge);
After doing some research, I found __VAR_ARGS__ on gamedev.net. Just one problem: Visual Studio 2008 is not aware for __VAR_ARGS__.
Am I misspelling __VAR_ARGS__ or something?
What header file is __VAR_ARGS__ (or its correctly spelled version!!) defined?
K, thanks!

|
|
varargs.h by any chance? 
|
|
|
|
|
Well, actually, I think I figured it out.
It's: __VA_ARGS__
#define PRINT(str,...) printf(str, __VA_ARGS__); //not __VAR_ARGS__ lose the first 'R'.
|
|
|
|
|
indeed, however vaargs.h won't cut it.
|
|
|
|
|
hehe. Yeah, I'm still searching for where __VA_ARGS__ *is* defined. I wonder if it's hardcoded into the compiler itself. The C99 standard says it should be supported - whether MS supports it or not I'm truly not at liberty to say until I've tested my still compiling application. (~700K lines).
|

|
|
|
I searched for varargs.h and only my WinARM and cygwin directories have those files.
Still searching the tree for __VA_ARGS__.
|

Hi, my folder C:\Program Files\Microsoft Visual Studio 9.0\VC\include
holds a varargs.h file containing definitions for _VA_LIST, va_start(ap), va_arg(ap,t), and more.
Yes, __VA_ARGS__ seems not to be there, I think you're right the compiler knows all about that one without any include file.
[ADDED]
Their documentation[^] knows about it; and you could test it with a much smaller program...

Looking at this page about variadic macros[^], it should be __VA_ARGS__?
You won't find it in any header file, though, because it's something built into the pre-processor.

i need help wrapping text for a clistctrl
i'm using either ownerdraw or customdraw to draw the items with multiple lines
my only problem is setting the individual row heights
i tried using ownerdraw + measureitem but that sets the heights of all the rows
any suggestions? thanks
|
|
|
|
|

that solution was for a ctreectrl
i'm now working on a clistctrl
i've been looking around and i dont think clistctrl has that iIntegral value to change the individual heights

imagine a struct declared as follows:-
typedef struct
{
int integerArray[];
} testStruct;
I can instantiate like this:-
testStruct a = {
{1,2,3}
};
Which is all well and good. But, if the struct declaration is changed to an int* member:-
typedef struct
{
int *integerArray;
} testStruct;
How can I now instantiate it so that integerArray points to my array of {1,2,3} ??
in gcc, you can cast {1,2,3} to (int *), as follows:-
testStruct a = {
(int *){1,2,3}
};
But msvc doesn't allow that. Is there another way to make this instantiation?
thanks

How about:
testStruct a = { new int(1), new int(2), new int(3) };

Very clever, anyway I suspect he wants the allocation to happen onto the stack.

How do we programmatically come to know whether an executable is digitally signed or not?
Is the signature in the form of section or a structure?
If it is like a structure then is there any document structure for it.
Does the size of the signature stored stored anywhere?
I am having two samples of same dll viz. signed and unsigned.
I find the difference in windiff only at the end of the files.
Thanks & Regards,
K. Sushilkumar.

You need to google first, if you have "It's urgent please" mentioned in your question.

Hi
I have an edit control which i have a character counter on
this works fine, but when i exceed 256 chars the cursor jumps to the start of the edit control
For my counter i am using
void CMyMessagePage::OnEnChangeEMsg()
{
UpdateData(TRUE);
int nBytes = lstrlen(m_message);
CString len;
len.Format("%d",nBytes);
m_sms_written = len;
UpdateData(FALSE);
}
Can anyone help
thanks

Check out SetLimitText(UINT /*param*/) API

thanks, i am already using SetLimitText
my problem is not the size of text allowed as i can exceed 256,
it is when i reach 256 characters the cursor jumps to the start
