Hi,

hm... interesting - and what type are x1 and mytext->contents -> is it CString too ? (I'm thinking about e.g. you use VS2005 where default is UNICODE defined and you try to compare default CString with char *)

Besides you can check what exactly return particular comparing functions (if equal should returns NULL)

What is this supposed to mean? If one of the calls to CompareNocase() is returning a non-zero value, which you have yet to verify, that indicates the strings do not match. Whether the strings match or not, your code is syntactically correct.

Means what ?
Can you try modifying it to,

If( (Loopname.CompareNocase(x1)==0) || (Loopname.CompareNocase(mytext->contents)==0))
{
  //do something 
}

ie only one case is wroking properly..Both together is not working..

If( (Loopname.CompareNocase(x1)==0)---This is working

(Loopname.CompareNocase(mytext->contents)==0))--This is working

If( (Loopname.CompareNocase(x1)==0) || (Loopname.CompareNocase(mytext->contents)==0))--But together is not working..

you are using a logical OR operator, which returns TRUE if one of the 2 operands is TRUE. so if its 1st part (1st comparison) is TRUE, then the 2nd one is not executed...

are you sure you want to use a OR ? don't you need a AND ( && ) instead ?

Ya..I have to use only "or" function..
but among them one is pointer and one is string..

mytext->contents is a pointer..

as in

AcDbMtext *mytext ;
mytext->Contents;

If( (Loopname.CompareNocase(x1)==0) || (Loopname.CompareNocase(mytext->contents)==0))

x1 is cstring and (mytext->contents)is a pointer..

what to do?? How t compare it?

Loopname is a CString, right ?

then look at the signature of CString::CompareNoCase(). it gets a PCXSTR parameter (so, pointer to char).

so ther's no problem in doing so.

if your code doesn't work, it is because of what i notified you previously. have you tried inverting the two statements in the OR operation (C-style string compared first) ?

Remember, Loopname.CompareNocase(mytext->contents) will not be called if Loopname.CompareNocase(x1) returns 0. (or rule)

What you've shown in now way indicates that contents is a pointer. While mytext is indeed a pointer, you've shown nothing of its contents member. If contents is indeed a pointer, what's it a pointer to?

Come on Satish !
You are still not reading answers well and replying to our queries well.
1. What does not working mean ? You need to be very clear.
2. Have you taken in to consideration when using || operator second operand will be looked only when first is false?

if this does not work, split the CompareNoCase and the if in different statements and debug each statement separatly.

bool b1 = (x1.CompareNoCase(s1)== 0);
bool b2 = (x1.CompareNoCase(s2)== 0);
if ( b1 || b2 )
{
}

Memory leak in IMPLEMENT_DYNCREATE(CMDIChildWnd)

rp_suman18-Dec-06 21:01

18-Dec-06 21:01

When I create a child frame and close it, a memory leak is reported in the output window as follows:
"childfrm.cpp(44) : {2414101} client block at 0x01AF7A00, subtype c0, 444 bytes long."
I would like to know what is possibility for this leak.

I am initializing only one bool variable in the constructor of child frame class.
I am having some user-defined functions in child frame class with return type LRESULT,
and a CSplitterWnd object which is used to create panes with CreateStatic() and CreateView() methods.
Is there any chance for leak from CSplitterWnd.
Is there function to delete the panes created by the splitter.
Any help would be greatly appreciated.

Thanks & Regards,
Suman

It is IMPLEMENT_DYNCREATE(CChildFrm ,CMDIChildWnd).
But I found that this leak happens only when the program stops with some error and selecting "Stop Debugging". The leak is not happening incase of normal halt.

That's normal behavior. CFrameWnd-derived windows delete themselves when they are destroyed.
If you stop the application before the window is destroyed (by it's parent in this case) then
it will show as a leak.

In this case, normal clean up routines does not get called . As Mark said, its normal behaviour.
