Hi,
I'm macking a Container application that hosts Activex Controls. I'm trying to provide scripting facility to my application using IActiveScriptSite. How do i expose the interfaces of the ActivexControl (i.e properties and methods) to the Scripting engine. any help would be highly appreciated.

I have a class A{ public :CString m_str;}
static int func()not in the class. How can I acess m_str in this function func()

make an object of this class like A b;
and use it like b.m_str; or make get set functions in class..and then use those functions..but first include this file into the file where your function is if they are in separate files Smile | :)

..i hope this works..
cheers

The case is as below
class A {public cstring mstr;
func();}

static int CompareModes(const void *arg1, const void *arg2 );
A::func()
{
....
qsort ((void *)lpModes, (size_t)cModes, sizeof(LPDDModeInfo), CompareModes);
}

int CompareModes(const void *arg1, const void *arg2)
{
CB *p1, *p2;
p1 = *(CB**)arg1;
p2 = *(CB**)arg2;

CString str1, str2;

str1 = p1->GetValue(mstr);
str2 = p2->GetValue(mstr);
return str1.CompareNoCase(str2);
}
here I need to access mstr in the static func CompareModes

hi,
thats what i was telling you..but i guess you didn't understood..anyway..inside your function like this

int CompareModes(const void *arg1, const void *arg2)
{
[red]
a b;
CB *p1, *p2;
p1 = *(CB**)arg1;
p2 = *(CB**)arg2;

CString str1, str2;
//in place of mstr use b.mstr and that will do..
str1 = p1->GetValue(mstr);
str2 = p2->GetValue(mstr);
return str1.CompareNoCase(str2);
}
i hope you r done this time..
cheers

I guess more info had to be given, A is a dlg class and I have a combo in it and onSelandOK I fill the mStr member. The on clicking another button I do some sorting and there in I need the mstr. So there is no point in creating a new obj in comparemodes. I need to access the member's value of the same obj that's calling func()

~~You should not retrieve the string value in CompareModes, but in your dialog. Extend your comparison function to pass the strings retrieved in parameter.~~ Cool | :cool:

Crap, you cannot since CompareModes is a callback. Why is your pointer cast not working ? Does it compile ? If yes, do you have an error at runtime ?

Re: access class members from a non class global static function

3-Feb-03 1:57

that's what was my secong idea..use get and set functions like..
void setmstr(cstring _mstr){mstr=_mstr;}
CString Getmstr(){ return mstr;}
so where you click to set mstr call setmstr() and it will store the value for you and where you need the value call getmstr() function which returns a CString..
so i guess that will do..
PS don't unfold the problem one by one..its gud to understand each and everything once..

Re: access class members from a non class global static function

3-Feb-03 2:11

well I guess Get/Set are member func if not I wonder how Get will return mstr??. If they are member funcs then back to square one!!! I did not know that I could access member funcs in global static function(CompareModes) then I would not have faced any problem Frown | :-(

Actually, what is your compare function comparing ? if you passed the dialogs as arguments, (I means arg1 and arg2 are dialogs), then your pointer cast should do :

CDialogA *pDlgA = (CDialog A*) arg1; // I'm not sure if i'm not missing a * here ...

and you should be able to access your data with p1->GetBlaBlaBla();

Hi,
Use WSAGetLastError(), instead of printing some message. From the error index it's easy to find out what went wrong. Smile | :)

iphlpapi and CPing

Hi,
I'm creating a program with MFC 6 that needs to do this:
- identify the default gateway of the machine where it is run
- ping that IP and detect wheter it answers or not

Actually, I've done both already. For the first I use iphlpapi, and for the second I use CPing.
Now, the problem is that this program needs to run in any Windows version, and my exe only runs in Windows 2000/XP. It doesn't run in 95/98, and it NEEDS to.
How can I do a program that does this for any Windows version?

I'd appreciate any help.

Thanks a lot.

Install winsock.dll version 2 on win95!

Well, the Windows 95 in which I'm testing does have winsock.dll (version n. 3.10). The first error it gave me was that it didn't find iphlpapi.dll. I installed this dll and the error message now is: "The file iphlpapi.dll is expecting a more recent Windows version". But I need it to work on Windows 95, so upgrading the Os is not a solution!

In WIndows 98 my error is: "The SAMLIB.DLL file is linked to missing export NTDLL.DLL:RtlUpcasedUnicodeStringToOemString".

In Windows 2000 it works perfectly.

In WIndows Nt the error is: "The entrance point to the procedure RtlDtringFromGUID couldn't be found in the dynamic link library NTDLL.DLL"

Any ideas?

Thanks so much.

I think this problem is taken from diference of NT and 98 to hande strings. Windows 95/98 do not support unicode. RtlUpcasedUnicodeStringToOemString function use unicode strings that Win9X does not support it. For adding unicode capability to Win9X, refer to this page[^].
