Hi, I am coding a Flash Video .flv player. It seems the sound of swf/flv file can not be turned off if the author of that swf/flv file doesn't provide a built-in sound controller inside the file.
Is there anyway around this?

Hi all,
First of all I am not exactly sure whether I can post this problem in this forum. If its wrong I am sorry for that. I am delibrately need a solution to this problem.
I am trying to create an executable, but when the .pc file converting to .c file I am getting lots of warning message like
<quote>
warning: old-style declaration or incorrect type for: main
warning: implicit function declaration:
warning: no explicit type given
of these 3 lines.
Any idea why I am getting these lines?
Any configuration issues?
What exactly needs to be done to solve these warning messages?
I am trying to compile this is new environment.
Any kind of suggestion would be helpful.
Thanks in advance

Hello, everyone.
I'm hoping this is the right place to post my question. I've been looking around on the net for the last couple of hours and haven't found a solution to my problem. (I did learned some new stuff for use in the future). So this is my situation. I have a program that lets the user create a response test using a movie. When I tried to draw on the movie the activeX controller always pushed its way to the front. So I've created a separate form that floats on top of the main form to draw on. The program also has three threads running, the main thread, a timing thread, and a thread that updates the floating form.
My problem is when I try and send a message to the floating form I trip a NullReferenceException. I've checked both the callback and my class, and both look properly initialized. The floating form is also correctly intialized. I've tried everything I could find, but nothing helps. I've included the method and the callback declaration. The floating form is called 'TestViewer' and the 'HOTSPOT' class is one I've created.
Thanks everyone for your help
(Sorry my code is in C++, but I know most people us C# or VB when programming in .net, and a lot more people frequent this form than the managed C++ one. If needed I can translate it into C#. Feel free to give me an answer in C#. Over the years I've gotten pretty good a translating C# to C++. Thanks.)
delegate System::Void SetDrawActivePanelCallback(HOTSPOT^ hSpot);
private: System::Void SetTestViewDrawActivePanel(HOTSPOT^ hSpot)
{
if(this->TestViewer->InvokeRequired)
{
SetDrawActivePanelCallback^ cb = (gcnew SetDrawActivePanelCallback(this,
&Edit::SetTestViewDrawActivePanel));
try
{
this->Invoke(cb, hSpot);
} // End try
catch(System::NullReferenceException^ e)
{
String^ s = e->ToString();
::MessageBox::Show(s);
} // End catch
} // End if
else
{
System::Windows::Forms::Panel^ panel = hSpot->GetPanel();
this->TestViewer->DrawActivePanel(panel, this->hotspotVisible);
} // End else
} // End SetTestViewDrawActivelPanel

This may not be your problem but shouldn't:

In the following example 1 I added rows to the DataSet
And I did not have any problem. However when I tried to add rows to a DataSet with more than one dimension I get the following error message at row 1 “Object reference not set to an instance of an object.”. I am unable to add the word new after equal sign. Does anyone know how to solve this problem.
Example 1
DataRow dr = dsI.EVar.NewRow();
dr["nRecordID"] = x;
dsI.EVar.Rows.Add(dr);
Example 2
DataRow dr = dsMI[x][1].EVar.NewRow();
dr["nRecordID"] = x;
dsMI[x][1].EVar.Rows.Add(dr);
Thanks in advance,
Michael

Maybe, but it's not possible unless you can provide specific information so someone can understand what you need.

Hi Mike,
Thanks for your early response.I am sending you the code for my class that needs to be used in .NET .I need to use this control CSizingControlBar in my Winform. CSizingControlBar is derived from MFC class CControlBar.I am migrating an application from MFC to .NET, there are few controls which require a lot of rewrite effort.Hence we wish to reuse the in .NET.It would be a grest help if you could provide with some feasible solution.
You could see one of my classe below.

The ToString method will allow you to specify a format. Assuming you're not in the wrong forum and are using .NET

Hi,
this can not be done.
new A() is an object, it could have a name.
objectA is not an object, it is a variable, it holds a reference to the
class A object. There could be many more references to the same object, it suffices
to do A* objectB=objectA;, now how would the class A object have to know
the name of all the variables pointing to it, and in particular the one you want??
Suggestion: give your objects a name by providing a Name property and/or a name argument
in their constructor, so new A("aha"); would create a new class A object and
give it the name "aha". Now you can ask that object for its name, and/or you can override
its ToString() method so it identifies itself. Remark: this works independently of the
variable(s) that may refer to that object!

Hello. I have to parse an HTML file and extract data from it. Currently I load it into Excel and then save as a .csv file. Then I load the .csv file and parse that. I now have to get the data directly from a web page into .csv format. Has anyone out there attempted something similar. Thank you.

Are you using C++ and .NET ?

I'm using VC++ 6.00 and Visual Studio 2005. I think IHTMLDocument will help me but I can't figure out how to implement it. I'm scouring the web for an example.

OK, so VC6 doesn't use .NET. VS2005 does. If you're not using .NET then you're in the wrong forum. Try the Visual C++ forum.

Hi Friends,
In socket programming I want to connect double byte charcters.
Earlier we used recv() function for single byte charcter.
If we use double byte chracter in below recv function, its coming as a question mark symbol.
If anybody knows how can I handle double byte charcter in Scoket programing(recv function),Please let me know.
My codesnippet:
while( bytesRecv == SOCKET_ERROR ) {
bytesRecv = recv( ConnectSocket, recvbuf, 64, 0 );
if ( bytesRecv == 0 || bytesRecv == WSAECONNRESET || CheckTimeOut()) {
return CloseListen();
}
}
Note:Here recvbuf works for singel byte not for doublebyte charcters.
Thanks in advance.

Looks like you're in the wrong forum. C++/CLI is C++ with .NET. You want the visual C++ forum.
