Hi,
I am working on VC++ project. Property Sheet has a number of property pages, so I want to highlight each property page TAB on its selection. Hightlight means it may paint each page TAB portion or should show same TAB text with different color.
Would you tell me the the way, How can I do it?
Thanks in advance,
Ramesh

You can do that in the OnSetActive() method...
Also take a look at the GetTabControl() method of the CPropertySheet Class. It returns a reference to a particular CTabCtrl object.
CTabCtrl class has a method called CTabCtrl::HighlightItem.
BOOL HighlightItem(
int idItem,
BOOL fHighlight = TRUE
);
Hope this will be sufficient for you...
Happy christmas friends. May the Love of My Lord and Saviour Jesus bring forth Joy and Happiness into your life too.

Thanks,
I want to re-modify my question.
When we select the property sheet page tabs, then the selected page tab text should change the color of page tab text or highlight the tab text.
Error is comming from the fallowing snippet that is,
<big>Error : " 'CPropertySheet::GetTabControl' : illegal call of non-static member function"</big>
How to access the GetTabContol() from CPropertyPage derived class?
<code>BEGIN_MESSAGE_MAP(CPage2, CPropertyPage)
//{{AFX_MSG_MAP(CPage2)
// NOTE: the ClassWizard will add message map macros here
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
BOOL CPage2::OnSetActive()
{
CTabCtrl *pTabCtrl = CPropertySheet::GetTabControl();
TC_ITEM item;
item.mask = TCIF_TEXT;
item.pszText = "New Label";
pTabCtrl->SetItem (1, &item );
// CTabCtrl::HighlightItem(1, TRUE);
return CPropertyPage::OnSetActive();
}</code>
wating for you reply,
- Ramesh.

I want to make an oracle db installer for my program. When it is executed it should be able to search the tnsnames.ora and list the services in combo box. Up to this it is finished(got the idea from http://www.codeproject.com/database/OSidList.asp)
Now, I want to:
1. logging to the service with login id and password :
2. after successful login all the users under the service should be listed. I can either choose the existing user or create a new user with sufficient rolls.
3. after that I want to execute scripts for creating tables etc. These scripts are stored in separate folder.
How will I write functions which perform the above tasks?

Hi all:
I'm under VC++ 7.0, and new to it. Regarding the following code
CFile file;
if ( ! file.Open(LPCTSTR ("C:\\Test.xml"), CFile::modeRead ) )
{
return;
}
After open operation why the file alway invalid?I don't see any problem!

Is Test.xml is exist at C:, as CFile::ModeRead will get failed if file requested isn't found.

to complete alok's answer, don't use the cast operator to LPCTSTR this way.
change the LPCTSTR(...) into (LPCTSTR)....
refer this[^] to understand...

I'll try that, thanks!
But here's another Que I encountered!
I can't use GetCurrentDirectory(...), I always get compiler error saying "identifier not found". Is it because of the project I started.
I started the project as VC++/SmartDevice

if ( ! file.Open( (LPCTSTR)"C:\\Test.xml", CFile::modeRead ) )
doesn't works either!

try
if ( ! file.Open( _T("C:\\Test.xml"), CFile::modeRead ) )

Are you sure there is a file with that name. Check the extension,name etc... to make sure

If this code is in function X, then as soon as you leave function X, the CFile object is destroyed (it goes out of scope). Thus the file will be closed.
Hope that helps.

hi friends
i have created one object called pIImage. I have to give the object pIImage as A argument to AddImage(). IN VARIANT type. how to convert one object to VARIANT type 
eg.
hr = CoCreateInstance(CLSID_Image,NULL,CLSCTX_INPROC_SERVER,IID_IImage,(void **)&pIImage);
pDoc->AddImage(pIImage)
error C2664: 'AddImage' : cannot convert parameter 1 from 'struct XYZ5::IImage *' to 'struct tagVARIANT'

If you look more closely at VARIANT constructors (more precisely, at _variant_t, you'll notice that one of them accepts IUnknown* and bool arguments. This is exactly what you need:
pDoc->AddImage(_variant_t(pIImage, true));

Hi,
I created a template class, just like:
template < typename TYPE, typename TYPE_ARG = TYPE > class DataList
{
public:
void AddNode( TYPE_ARG val_i )
{
SetVal( val_i, valNew );
}
protected:
struct NODE
{
NODE* pNext;
TYPE val;
};
virtual void SetVal( TYPE_ARG valSrc_i, TYPE& valDst_o )
{
val = val_i;
}
};
This is only a model. I use this class for a general purpose linked list.
I derived a class for string handling, just like:
class StringDataList : public DataList < LPTSTR, LPCTSTR >
{
private:
void SetVal( LPCTSTR valSrc_i, LPTSTR& valDst_o )
{
valDst_o = new TCHAR[ lstrlen( valSrc_i ) ];
lstrcpy( valDst_o, valSrc_i );
}
};
Thus I can use the template class for both numeric data handling and string handling.
For example:
DataList < int, int > intDataList;
StringDataList strDataList;
The real problem is, we assume that the input parameters should be const, especially for pointers (that's why I use LPCTSTR as TYPE_ARG in StringDataList).
So the compiler shows error in the base class while compiling StringDataList.
The error is error C2440: '=' : cannot convert from 'const char *' to 'char *'
If I change the TYPE_ARG to TYPE in the SetVal of template class, another problem arises. That is in the AddNode. It is written as to pass the const input value to the SetVal. To clear it, I have to change the input from TYPE_ARG to TYPE. It is OK for all the classes passing value, but for string type, it is not advisable.
One solution is, I think, use type cast in SetVal, just like
val = TYPE( val_i )
Is there any other better solution?
Thank you.

I think we had a discussion on constant string
when u had put up a question before few days.
I have already lost that data but will try again
for the same
but the changes u have done in the class are
quiet good.
Pls put up ur class on codeproj when u acomplish it

Hi
Is the GUID of a COM object unique through out the network or unique through out the world
|
|
|
|
|
Theoretically, it's unique, as they call it, 'both in time and in space', but it depends on the actual algorithm used to generate UUIDs. However, you can be reasonably confident that these are unique.

I have code like this:
<br />
BOOL f() {<br />
...<br />
__try {<br />
...<br />
}__except(EXCEPTION_EXECUTE_HANDLER)<br />
{<br />
...<br />
}<br />
<br />
Object o;<br />
}<br />
The object declaration of variable 'o' is outside the __try/__except construct. I get the error:
warning C4509: nonstandard extension used: 'f' uses SEH and 'o' has destructor
Why is this so? I was thinking this should not be an issue as even if an exception is thrown, it will be handled by the __except block, and the exception stuff would end there. The object o is then created.
What can I do to fix this error?
thanks!

firstly, it is not an error, it is a warning. that means that the compiler saw that there is some coude that may cause some trouble, but non blocking for the execution of the program.
i have one question however. why are you using __try/__except instead of try/catch ?
refering to the MSDN[^], you have to declare o before the exception handling... (SEH means structured exception handling).
