Thanx a lot ,,Prasad...

dynamic cast was not required
This is enough:
CTreeCtrl* pCtrl = (CTreeCtrl*)(CWnd::FromHandle(HandleToTreeView));

NeWay thaks a lot again.....

This works, but C++ standard encourages using dynamic_cast or other operators(reinterpre_cast,static_cast) . And old function style casts should be avoided wherever possible.

Hi,

You trying to be too fast Wink | ;-)

I have code..

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

but its not working

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.

Here it is wrong, using your way.

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 )
{
}
