In addition to what Edders said, there are numerous codecs out there like G.711, GSM, G.729, iLBC, Speex, etc. And you would need to know and understand all of them.

Hi All,

I want to do a simple ActiveX control, which will basically be a wrapper over a C++ VoIP library/application. The intent is to embed the softphone in a browser so that the application...

#include <iostream>
#include <string>

using namespace std;

int dan ();

int main()
{
//Let's call our function

Use the two pointer approach.

Rough code:



bool ContainsLoop (Node *pNode)
{
Node *pSlowptr = pNode;
Node *pFastptr = pNode->pNext;

Thanks a lot for the replies :). Things are clearer now.

Yes, I understand that it can help avoid the extra code in the release build. All you said makes sense.

So, does the author mean to say that whenever your application asserts then it's a bug and...

Hi,

Steve Maguire in Writing Solid Code mentions how his re-write of an old library, which previously had no assertions, caused so many assertion errors in the code that now used the new library....

Hmmmm, I can't rate. But, thanks a lot Sir!

1) Ok, thanks :).

2) SVN did exactly what I wanted.

Can Visual SourceSafe do what I want?

Hi Guys,

What access level (private, public, protected) should be given to the different message handlers in my application? I generally declare all the variables for the controls as private, but...

Thanks a lot. That does what I need.

Ofcourse, I know that. And, I update my controls by sending a message to the window that created them. But, the question over here is, from an another thread how I get the items selected in the list...

Thanks for the response first of all.

Yes, the property page is created by the main thread. The reason I'm worried about thread safety issues is that I make updates to the list control from a...

Hi Guys,

I have a property page which has a list control on it. I need to know the number of items in the list control and read the text of the items from my main dialog box, so how can I do this...

Thanks, I will now fix it. Between, I'm not able to find your article on Multiton, can please give the link?

Thanks for the reply.

Are there any other ways to make the application thread safe? Or the only way is to send user defined messages to the property page, and ask it to update the list control?
...

CString strValue;
for (int i = 0; i < m_cmbValues.GetCount (); ++i)
{
m_cmbValues.GetLBText (i, strValue);
if (!strValue.CompareNoCase (_T("1")))
{
m_cmbValues.SetCurSel (i);...

Sorry, but your header and implementation files are not correct. On a sidenote, don't be afraid of errors, we all get them.

I have a dialog based application that has two property pages over it. The property page has a list control, basically the app is a softphone and the list control shows the active calls and it's...

Guys, thank you for the responses [:)].

Another thing that you may do is to remove the Accelerator associated with Ctrl + C in your project.

class Foo
{
int data;

public:
Foo (int n):data (n)
{
}

Foo ():data (0)

The errors show that you have not linked with the library.

Right click on the solution->Properties->Linker, in Additional Dependencies enter the name of the library.

Set the Read Only property of the edit box to be TRUE. The DDX/DDV routines work fine even if the edit box is read only.

You can do it this way as well:


CString strText;
GetDlgItem...
