It is when I assign a brush color I think.
|
|
|
|

The assertion says that there is already an object handle associated with you CGdiObject class. You probably attached a GDI object (a brush?) to the variable previously and forgot to detach it before you reused your object to the new brush.
If this is not the case please post the code where you use the GDI object and class.

Do you have a fixed IP-address for your home computer?
Do you have a firewall on it?

Has anyone know how to fix the dsw or dsp in vc when the class tab (info) is lost?
To be very simplistic about it The class tab works, their is no info or + - signs or
eval globals(theApp)
The project still works fine, I went back 1 hour and still no luck.
Any idea's ?

In the context of C++, is there technically a difference between, qualifier and modifier. I have seen the phrase "const modifier" and "const qualifier" used interchangeably. Clarification and/or references would be appreciated.
Thanks

In the document, "ISO/IEC 14882:1998 Programming languages -- C++",
section 7.1.5.1 The cv-qualifiers [dcl.type.cv]
1. There are two cv-qualifiers, const and volatile. If a cv-qualifier appears in a decl-specifier-seq, the init-declarator-list of the declaration shall not be empty.

Are qualifier and modifier really c++ syntax? I don't think so. If they're not it's perhaps just names used for functions with a special purpose.

How do you delete doubles of an element in a vector??
|
|
|
|
|
Sort the vector first (so duplicates are consecutive), then see: unique()

What is the exact differece between event and mutex w.r.t thread syncronization. I found that they can be used interchangably so where excatly is the difference. If possiable can any one give an example where event will be used and where mutex can be used.
thanx in advance.

Events can be fired by lots of different threads at the same time, I think, whereas a mutex is something owned by one thread only.
So when a thread is waiting for an event, it can be fired by more or less any other thread, whereas if it is waiting for a mutex, it is one specific thread that releases it.

Hi:
I want to change the background color of the CTabCtrl（such as the area that doesn't be covered by the tabs）.I try onctrlcolor() and onerasebackground(), but seems that they don't work. The background color is always the default one.How could I do? I search this site, but can't find a solution that works .
Thanks
