So are you going to tell us what that function call is?

If you do not need that specific driver, just opt to not install it.

What about?
if (!bAdminRights)
return;
//...the function itselfs
at the beggining of every function that should be called only with admin permissions.

Hi, everyone!
I meet a strange problem. The application I'm developing has a parent window and a popup dialog. I wrote a class encapsulate a SOCKET and declare a varriable of it in the parent window. When some data were received, a message will be sent to parent window. Then when the dialog is popupped, I use a pointer of the class and let it point to the varriable in the parent class. After that, I assign the dialog's HWND to the class. So the message will be sent to the dialog as I think. But the fact is the class can't work when the dialog displayed at all! I think declareing a new varriable will cost too many CPU's time because the class generate a new thread. So I hope someone could be kind to tell me how to resolve this problem without declare a new varriable. Thanks!

Hi Pal,
Seems very difficult to understand the problem you are facing... please describe more clearly.
Regards,
Jijo.

The essential of my problem is that what time is approprate to assign a handle of a dialog to a varriable. In InitDialog() or in WM_CREATE processing function? If the time is wrong, the message can't be received.

Is this a modal dialog?

Maybe I can resolve this problem by other way. If I success, I'll tell everyone answered.

Hi guys, I have the second question about template. I encountered it during my studying.
for example, I have a template class both in .h & .cpp files as follow:
1:
2: template < class T >
3: class TTEST
4: {
5: public:
6: struct TS
7: {
8: int i ;
9: } ;
10: public:
11: TS* test1() ;
12: } ;
13:
14: #include "a.h"
15: template < class T >
16: TS* TTEST < T >::test1()
17: {
18: return NULL;
19: }
But I got a compiler error at line 16 while building it. I know there is something wrong with the " TS* ", but I don't know how to fix it. Could an y one help me ? thx !

Try to replace the function definition (.cpp file) with:
template < class T >
TTEST < T >::TS * TTEST < T >::test1()
{
return NULL;
}

Hi, CPallini. I have tried this way before, and failed with a similar error, in vc.
|
|
|
|
|
Strange, it works fine on my system (VS6).
Are you sure the sintax was the same?

Then you must've made a type-o. Simply qualifying TS is all that's needed.

I think it has nothing to do with templates. I thnk in the CPP file you need to put TTEST::TS *, because the struct is defined inside the class.

I think u should modify the code as following:
<br />
1:
2: struct TS<br />
3: {<br />
4: int i ;<br />
5: } ;<br />
6: template < class T ><br />
7: class TTEST<br />
8: {<br />
9: public:<br />
10: TS t;<br />
11: public:<br />
12: TS* test1() ;<br />
13: } ;<br />
14:
15: #include "a.h"<br />
16: template < class T ><br />
17: TS* TTEST < T >::test1()<br />
18: {<br />
19: return NULL;<br />
20: }<br />

thanks for focusing ! I agree with you that it will work in your way, but to put TS's definition inside class TTEST will be more preferable.
|
|
|
|
|
Remeber you cannot implement a templated class's member functions in a separate .cpp file. You have to put the implementation in the .h file along with the class definition. Try moving all your original TTEST code into the .h file and see if it compiles them.
This is a limitation of C++ compilers which I can't at the moment remember the excuse for. You may need to ask Mr Stroustrup
Nothing is exactly what it seems but everything with seems can be unpicked.
|
|
|
|
|
haha, thx for focusing, Matthew ! I am afraid Mr Stroustrup will be too busy to reply me. I know the way to separate a template into .h & cpp files. You could search it inside codeproject(I couldn't remember the exact link).
|
|
|
|
|
Probably Mr.Stroustrup don't know that C++ Compiler is so smart to generate function using only declarations
