A general compare of all sync object types would take a bit of space ... and then likely be incomplete.

Do you have specific cases ?
e.g. critical section vs mutex in a situation where ...

As cmk mentioned, you should list certain situations and scenarios. You mentioned that you've used different sync objects in the same situtation, and they all worked fine. What situation and which objects?

deleting CPropertySheet

Hello,

Based on a CComboBox control selection, I want to load CPropertySheet into a dialog-based MFC Application. I have 3 CPropertySheets in my project.

Inorder to do this, based on event :OnCbnSelchangeComboBox(), I want to delete existing CPropertySheet control and load the selected one.

How can I do this? Do I have to delete each & every CPropertyPage page and then add new CPropertyPage pages?

Is there any way that deletes total CPropertySheet once?

Regards,
mysticlol

Why don't you try showing the needed sheet, and hiding the not needed ones.
Like:
when sheet1 is needed:

m_Sheet1.ShowWindow(SW_SHOW);<br />
m_Sheet2.ShowWindow(SW_HIDE);<br />
m_Sheet3.ShowWindow(SW_HIDE);

Similarly show / hide them when needed.

this is this.

FindWindow() Fails

Hi All....

FindWindow() fails, even if instance of that application is running. When the first instance of the application runs, windows title is set.
Next time around, if I try to find the window using same string, it returns NULL. GetLastError() returns me ERROR_SUCCESS-0 code.

Can anyone explain Reason for this?

If you could be a little precise, you will get the problem solved by someone out here. The narrower your question is, the clearer people can answer.

1. What do you want to know about ACL?
2. What source code?
3. How exactly are you going to use it?
4. What exactly are you going to do with ACL?

However, this[^] might help you.

Error with templates

5-Dec-05 14:55

I all.

I got the following class headers (on declaration):

template <class t=""> class tVar { blá, blá, blá... };
template <class t=""> class tDoubleLinkNode : public tVar<t> { blá, blá, blá... };
template <class t=""> class tDoubleLinkList : public tVar<tdoublelinknode<t> *> { blá, blá, blá... };
class tMemCount : public tDoubleLinkList<smemcount> { blá, blá, blá... };

and sMemCount is:
typedef struct sMemCount {

uWord Amount : 10; // Amount of memory (0..1023)
eMemMultiplier Multiplier : 6; // Memory multiplier (0..63)
// This is a enum

} sMemCount;

And many other classes that do not interest rigth now. I have done the whole thing in separated modules, so, the classes definitions (such as the ones above) are in some .h file and body functions in .cpp file. The thing is, i am getting the following errors under VC++ 6.0:

memc.obj : error LNK2001: unresolved external symbol "public: __thiscall tDoubleLinkList<struct smemcount="">::~tDoubleLinkList<struct smemcount="">(void)" (??1?$tDoubleLinkList@UsMemCount@@@@QAE@XZ)
memc.obj : error LNK2001: unresolved external symbol "public: __thiscall tDoubleLinkNode<struct smemcount="">::tDoubleLinkNode<struct smemcount="">(void)" (??0?$tDoubleLinkNode@UsMemCount@@@@QAE@XZ)
memc.obj : error LNK2001: unresolved external symbol "public: __thiscall tDoubleLinkList<struct smemcount="">::tDoubleLinkList<struct smemcount="">(void)" (??0?$tDoubleLinkList@UsMemCount@@@@QAE@XZ)
Debug/ucd.exe : fatal error LNK1120: 3 unresolved externals

In the .h file i have the constructor definition:
public:
tDoubleLinkList ( void );

And in the .cpp i have written:
template <class t=""> tDoubleLinkList<t>::tDoubleLinkList( void )

And the same to all.

Any sugestion about those errors Confused | :confused:

!? Thx!

Your error message simply means that Windows can't find the program (getmac.exe), neither in "C:\Documents and Settings\Administrator" nor in the PATH.

So, where did you put that program?
