Ok, this is my first time posting so bear with me. I have to write a battleship program; you play against the computer AI. I have everything close to working but when I put in the code for the computer to guess a random spot and color that spot if it was a hit, it says debug assertion failed, wingdi.cpp, line 1120. It seems to have to do with my RePaint function coloring the square. Is there an easy way to fix this?

If you can run it in a debugger, where you can get a stack trace when the assertion fires, you'll be able to see what bit of your code it doesn't like. Post the relevant snippet here.

When I do that its the stdafx header here(->):
BOOL CGdiObject::Attach(HGDIOBJ hObject)
{
(->) ASSERT(m_hObject == NULL); // only attach once, detach on destroy
if (hObject == NULL)
return FALSE;
CHandleMap* pMap = afxMapHGDIOBJ(TRUE); // create map if not exist
ASSERT(pMap != NULL);
pMap->SetPermanent(m_hObject = hObject, this);
return TRUE;
}
Any ideas?

Anyone know how to fix it?

In debug the call stack window points to this:
CGdiObject::Attach(void * 0xb5100c1d) line 1120 + 28 bytes
|
|
|
|
|
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.

It works fine within my computer(both server and client running in the same computer), but when I try to connect to the server program (running in my computer) form other computer ( from internet cafe') it doesn't connect.... I think I am missing something. could you please give me some suggestions or information useful to make my clinet program connect with the server program running in different computer. thanks!!!!

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()

Hi,
I have two questions on mixing use of MFC and Win32 ,
1. How can I create Win32 childWindow in CDialogs or in other MFC classes after creating a project by MFC AppWizard in eVC3.0 ?
2. How can I create MFC CDialog after i create a pure Win32 application in eVC3.0 ?
Any books or material that i can refer to on the above two problems ?
Thanks so much
