Reading IE history with C++ console app...Possible?

10-Jan-07 21:31

I was searching MSDN for a function that will read and output (or store) IE's history cache of visited websites, but couldn't find anything useful. I would greatly appreciate if somebody would point me in the correct direction to do this. Thank you in advance. Smile | :)

There are a number of free ASPI layers you can use. After a quick Googling I found this site:http://www.afterdawn.com/guides/archive/aspisetup.cfm[^]

I'm using Adaptec's ASPI layer in my applications. It works, even in XP, though Adaptec (appearantly) doesn't guarantee it.

Check out the SetClipboardData function. To but a bitmap on the clipboard use CF_BITMAP, CF_DIB, CF_DIBV5 or CF_DIBV5 or to put a file use CF_HDROP.

Thank you.

yes, i already try this function and COleDataSource::SetClipboard().
but they are not work. and below is my code.

<br />
if ( OpenClipboard() )<br />
{<br />
EmptyClipboard();<br />
SetClipboardData(CF_BITMAP, m_hDrawingSurface);<br />
CloseClipboard();<br />
}

code using ole

<br />
COleDataSource* pDataSource = new COleDataSource;<br />
TRY<br />
{<br />
	// Create a shared file and associate a CArchive with it<br />
	CSharedFile file;<br />
	CArchive ar(&file,CArchive::store);<br />
	BITMAPFILEHEADER bmfh;	<br />
	int nBitsOffset = sizeof(BITMAPFILEHEADER) + m_bmpInfoHeader.biSize; <br />
	LONG lImageSize = m_bmpInfoHeader.biSizeImage;<br />
	LONG lFileSize = nBitsOffset + lImageSize;<br />
	bmfh.bfType = 'B'+('M'<<8);			<br />

	//And then the bitmap info header<br />
	ar.Write(&m_bmpInfoHeader, sizeof(BITMAPINFOHEADER));<br />
	ar.Write(m_pDrawingSurfaceBits, lImageSize);<br />

You need to set the profile on the writer before using GenerateKeyID().

I see it loaded but not set in the writer with SetProfile().

well actully in the doc i have read the following.

Calling this method removes any previously set header attribute information.

Changes to the profile object made after this method is called do not take effect until SetProfile is called again.

so i think might be used previosly set. is it neccessary to set ? becasuse before it. it works fine then i have little change in the GUI and now its not worked.
i have setprofile in the createwrite function which call from compress function
Please check the function(Compress) with the previos code which call from their.

have you checked my previous comment.in that i have written some thing specific please read it. according your guidline i have add the profile object in the
following function.
i dont understand even who it works when it is NULL,
OR how can i set the value of profile ?
please give me guidline with code.

i am not sure but i have write it and it gives E_INVALIDARG.

I see all your replies - I had to sleep a bit. It was around midnight here my last posts Smile | :)

The code in the other reply looked ok. You need to create the writer, set its profile, and then
set the DRM key. Maybe call your GenerateKeyID() after creating the writer (from your CreateWriter() function?, after setting the profile). Pass the created writer object to
GenerateKeyID() instead of creating another writer object there.

Dear Mark ,
thanks for replay me actually been waiting for your replay then i left the office
ok fine ,but have you checked my code and understood function flow properly or i should give you the flow of my functions.
bcoz its real needed otherwise might be wrong somewhere.

please checked compare an clear the flow.

try to set the profile two way one is inside the generatekeyID()
and second is before the function called.

EncodeMediaContent()
{

LoadSystemProfile();
//here set prfile //write now this is active
generatekeyID();//also inside this function also setprofile inactive
GenerateConfigurePackageRequest();// the last param use the generated key
if the response return success from the server
compress() //call and inside this CreateWrite call and the protect file call

}

please checked all this
the one and most important question is on which base the key generated on the client machine.

This code looks OK except Encoder::GenerateKeyID().

In Encoder::GenerateKeyID() you create another writer which doesn't have a profile set so the
GenerateKeyID() is going to fail.

What if you change Encoder::GenerateKeyID() to something like

WCHAR *Encoder::GenerateKeyID(IWMWriter *pWriter)
{

HRESULT hr;
IWMDRMWriter *pDRMWriter = NULL;

hr = pWriter->QueryInterface(IID_IWMDRMWriter,(void **) &pDRMWriter);
DWORD d_KeyID = NULL;
hr = pDRMWriter->GenerateKeyID(NULL,&d_KeyID);
WCHAR *w_KeyID = new WCHAR[d_KeyID];
//w_KeyID=NULL;
ZeroMemory(w_KeyID,sizeof(WCHAR)* d_KeyID);
hr = pDRMWriter->GenerateKeyID(w_KeyID,&d_KeyID);
//w_KeyID=L"mXMzxuQy8PEkwSgv2gcfEA==";
pDRMWriter->Release(); // Don't forget to release your COM objects! :)
return w_KeyID;
}

Pass it the writer pointer (m_pWriter) that you created and set the profile of in
EncodeMediaContent(), like this

WCHAR *w_KeyID = Encoder::GenerateKeyID(m_pWriter);

I'm not sure what you are asking. What exactly are you trying to accomplish?

DRM is a fairly large topic...

Digital Rights Management Features[^]

Enabling DRM Support[^]
