I do not see the point of your code  Why using a POSITION if you delete it two lines after ?
~RaGE();
|
|
|
|
|
Actually the statement of 'delete pos' doesnt make sense !!
pos is just a stack variable and its value is not necessarily
a pointer.
|
|
|
|
|
Ok. If POSITION and pos r not required can u pls. suggest how to release the memory associated with the element in the CList after you read that? Cause RemoveHead()is not doing that.

how abt 'delete pMess' ???
|
|
|
|
|
No Prem,
even that doesn't work.Just now i tried with that also. Its giving the same error.
Rsh
|
|
|
|
|
As far as I know (but I may be wrong) if you delete an Item with RemoveHead(), itreturns a pointer on the deleted item. So let´s use this to delete the already-deleted-in-the-list Item ... no ?
~RaGE();
|
|
|
|
|
Are you just trying to iterate through the list? If so, there are easier ways, I will elaborate if needed.
Otherwise, just remove the line that says 'delete pos;'. As was stated this is a variable declared on the stack. Trying to delete it will cause debug assertion errors. (Worse yet in release mode)

what exactly i want is, to read the elemnts from the headposition in Clist and immediately after reading,would like to delete the already read element from the list & also release the memory that was associated with the deleted element.
Can anybody pls. elaborate on this
The code is as follows
void CPLayerApp::LockIt()
{
unsigned char data[10],mCnt,mMid;
unsigned char *ptr;
CMessage* pMess;
CMessage* delMess;
CSingleLock singleLock(&m_SyncLock.m_mutex);
CString str="";
while(1)
{
if(m_messList.GetCount() != 0)
{
singleLock.Lock();
pMess = &m_messList.GetAt(m_messList.GetHeadPosition());
mCnt = pMess->m_cnt;
mMid = pMess->m_mid;
pMess->GetData(data);
//POSITION pos = m_messList.GetHeadPosition();
m_messList.RemoveHead();
delMess= &m_messList.RemoveHead();
//pMess=(CMessage*)m_messList.RemoveHead();
delete delMess;
singleLock.Unlock();
if(data[0] == 0x10)
{
str.Format("%0x",data[0]);
AfxMessageBox(str);
break;
}
}
Sleep(200);
}

I find that by creating a new frame and loading it wil the OnNew() event works. Its not a child frame in the true sense but it loads in a new external window. However I do not know if this is what u want.

sorry, Jonny. i didn't catch your mean. "not a child frame in the true sense but it loads in a new external window"?

Write a new cpp file with a new Window in it. Then call it from the OnNew() function with ShowWindow()

A VARIANT which is an array of VARIANT's, surely ?
If you have 50-60 global variables, you're bound to burn in hell anyhow. Globals are rarely necessary, almost always a bad design, and 50-60 is just an incredible achievement IMO.

Create a new ATL object and add properties to the object that return the global variables.
It's probably the easiest way to do it, although it is a bit of a hack.

An ATL object with 60 properties sounds bad to me!

It's not many more than your standard ActiveX control. You could even just use methods with multiple out parameters.
Good to see you back Nish.

But those properties are set at design time, aren't they? And I doubt if it is advisable either! Anyhow, I might be wrong! My COM awareness is still pretty raw, despite Mike Dunn's noble attempts via Sonork

Properties can be set at run time or at design time. You can specify properties to be get only, so you can't set them at all. A property is just a wrapped method really.

You hadn't posted for a while, so I assumed you had taken a break. Although a browse of the forums shows you've been here, just not been as prolific with your postings.

Hi, I was wondering if anyone knows how to access (wav)files (on a cd-rom) that are shown as *.cda?
The file it´self is shown as 1kb large (although it is just 44 bytes long, as it is the wav header).Is there anyway I can access the file (like drag and drop or copy) as a normal wav file (i.e. like the alternative cdfs.vxd under Windows 9x os´s ?)
Thanks in advance
Phil

The cda files are references to the start/finish of a track. Audio CD's are different to CD-ROMs in the way they store stuff. You will need some kind of ripping software. Windows Media Player 7+ or RealOne Player will do this.

I was tinking of doing the "ripping" myself, so far I´ve found out that in the cda file is the start and end sector of the "music", the track number and a few other things (time in minutes, seconds etc.). Is there any way to read the cd directly i.e. low-level api ?

How to zip and unzip files easily? Does anybody know
some easy library (lib/dll)

Yes, it's called zlib. Plenty of info on the web. I've never used it myself, but I'm told it works well.
