i might be wrong, but i don't think you can do conditional drawing inside EMFs. at least, you can't save the condition - of course you can draw based on whatever logic you want, you just can't save the app logic along with the GDI commands.

Ofcourse I did some logic inside my app for this. Let me show some code snippet that I did experimentally.

int CALLBACK EnhMetaFileProc( ...... )
{
static bool bTextout = true;
if( lpEMFR->iType == EMR_SELECTOBJECT )
{
PEMRSELECTOBJECT p = (PEMRSELECTOBJECT)lpEMFR;
LOGFONT lf = { 0 };
if( sizeof(lf) == ::GetObject( lpHTable->objectHandle[p->ihObject], sizeof( lf ), &lf ))
{
if( lf.lfHeight >= -35 )
bTextout = false;
else
bTextout = true;
}
}
if(( lpEMFR->iType == EMR_EXTTEXTOUTW ) || ( lpEMFR->iType == EMR_EXTTEXTOUTA ))
{
if( !bTextout )
return TRUE;
}
::PlayEnhMetaFileRecord( hDC, lpHTable, lpEMFR, nObj );
return TRUE;
}

My problem is that I dont know how to identify the scaling. For example, how can I identify the following inside the EnhMetaFileProc...
EnumEnhMetaFile( dc, m_hEMF, EnhMetaFileProc, 0, CRect( 0, 0, 100, 100 ));
EnumEnhMetaFile( dc, m_hEMF, EnhMetaFileProc, 0, CRect( 0, 0, 500, 500 ));
Also I am not sure whether this is the correct method to do.

I did not get any details about this yet from MSDN or from net... Frown | :(

Crack Protection like Remind! 5.45 and Macro Toolsworks 6.31 ?

Hi
I have worked with some nice apps like Remind! 5.45 and Macro Toolsworks 6.31. Many crackers have reported that such apps are not easy to crack.

Any guess, how they would have implemented crack-protection. If any one has idea or experience how to implement such crack-protection.

I need to implement similar crack protection in our VC++/MFC App. The idea is to make it more dificult to crack (i.e. with some check for anti-debugging, anti-cracking and anti-softice etc.)

I truly appreciate any help/ideas/reference links.

Thanks
Ana

You can create an XML file with the following content:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <br />
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"><br />
<assemblyIdentity processorArchitecture="x86" version="5.1.0.0" type="win32" name="XPLooks" /> <br />
<description>Test Application</description> <br />
<dependency><br />
<dependentAssembly><br />
<assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" publicKeyToken="6595b64144ccf1df" language="*" processorArchitecture="x86" /> <br />
</dependentAssembly><br />
</dependency><br />
</assembly>

Save the file as, for example, xptheme.xml

Then go to ResourceView and import this file. In Custom Resource Type, fill in "24" in Resource type. Finally, set the ID to "1".

Hi,

I need to handle del key for a dialog based appliation.what should I do??

I did as shown below .

void C3DColorCardDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
	// TODO: Add your message handler code here and/or call default
	AfxMessageBox(_T("C3DColorCardDlg OnKeyDown"));
	if (nChar == VK_DELETE)
	{
								
	}

	CEFCBaseDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}

The problem is I am not getting the Message box on pressing a char or Del key.

Any Suggestions would be helpful.

Thanks
Satya

Make a query for Win32_NetworkAdapterConfiguration class.
DNSHostBName attribute is what you need.

regarding WAV to MP3 converter

hi all
i am developing my own WAV toMP3 converter.i have seen method for mp3 conversion and they say that particular frequency range of sound data should be eliminated.
i wanted to know how to do that?as there is no field in WAVE header from where i can know the frequencies.
thanks i advance

Re: regarding WAV to MP3 converter

Dmitry Khudorozhkov6-Apr-07 0:52

The asnwer is that you must manually analyze the raw wave data stored in WAV file, either by fourier analysis or any other means. That is the way good WAV->MP3 converters work.
