Well, you need something a bit more elaborated (plain C):
void myAlloc(int ** ptr)
{
*ptr = (int *) malloc(sizeof(int));
}
int main()
{
int * pMyInt;
myAlloc( &pMyInt);
*pMyInt = 5;
printf("%d\n", *pMyInt);
free( pMyInt)
}

when i initialize a list iterator with an integer, it gives compile error as follows:
list <int >::iterator iter;
iter = 0; //this gives an error c2679 when build in release mode
but the same code works fine when i build in debug mode.
why? can any body put some light on this?
(am using visual studio 2005)
thank u

what if you initialize the iterator correctly ?
list <int>::iterator iter;
iter = mylist.begin();
where mylist is an instance of the class list<int>
|
|
|
|
|
This[^] explains why (debug mode has the _HAS_ITERATOR_DEBUGGING macro set)
In general you shouldn't create iterators from pointers (0 is being treated as the NULL pointer). If you want to ensure that the iterator references nothing then set it via mylist.end().

in my dll I am exporting a function
extern "C" __declspec(dllexport) void __cdecl setdata(int num);
in my application I defined the function
typedef void (__cdecl *SETDATA)(int num);
SETDATA setdata;
now I write the code
HINSTANCE hDll = LoadLibrary("mydll.dll");
if(!hDll)
{
return;
}
//ok fine library load
setdata=(SETDATA)GetProcAddress(hDll,"setdata");
//here it setdata not receiving and show NULL address of setdata function why?
but same working fine when I statically link?

From GetProcAddress documentation [^]:
Return Value
If the function succeeds, the return value is the address of the exported function or variable.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
BTW Have a look at the actual exported function name (you may use depends.exe for the purpose).

That is: "The specified procedure could not be found".
Have you used depends.exe to see the actual exported name of your procedure?

Hi,
I am using CListView control, there to get the ClistView style i used a message ON_MESSAGE "LVM_GETVIEW", i define a method for this message, but when i complied it throwing error as
error C2065: 'LVM_GETVIEW' : undeclared identifier
please help me.
|
|
|
|

Did you include (as required) commctrl.h?
BTW I think you should use SendMessage with LVM_GETVIEW, see [^].

Hi,
yes, i include "commctrl.h". i am using in mfc, so it is possible to "SendMessage" ?.
i used as
ON_ Message(LVM_GETVIEW,onGetStyle)
then i implement onGetStyle()method. After that i complie it, an error message was occur "error C2065: 'LVM_GETVIEW' : undeclared identifier" at compile time itself

Ok, from a previous post of yours, I thought the opposite. Anyway, if you are using MFC, why not simply use GetView[^] ?

Yes.

You have to define _WIN32_WINNT greater or equal to 0x0501.

As far as I remember, you were using the Win32 API and no MFC, right ? ON_MESSAGE is a MFC macro.
