Webbrowser control + ActiveX

Hi,

Is it possible to enable/allow ActiveX controls inside my webbrowser control (CHtmlView).

Please do not say it is not possible! Frown | :-(

Niki

PS: Background: I'm writing a database application where data is stored in html format. There are also popups (similar to the old WinHelp32) which are implemented using JavaScript (or similar things; these scripts are not written by me). When I open such a HTML file directly in IE I get the security warning (even when all files are local). In my webbrowser control I even do not get a warning but only script errors.

I have found CoInternetSetFeatureEnabled.

But nothing changes Frown | :-(

I have already set FEATURE_WEBOC_POPUPMANAGEMENT, FEATURE_SECURITYBAND, FEATURE_LOCALMACHINE_LOCKDOWN, FEATURE_RESTRICT_ACTIVEXINSTALL. But nothing changes Frown | :(

I again get a script error with "Permission denied" Frown | :(

The problem was not the browser control itself but my async pluggable protocol!

I missed to handle PARSE_SECURE_URL for the secure manager so two different URLs in my protocol were essentially in a different domain.

So I got "permission denied"-messages when accessing different frames (cross frame scripting prevention)

static-inheritance problem

Hello, I have a problem with static variables and inheritance

<br />
<br />
class BVolume {<br />
protected:<br />
enum { NONE = 0, SPHERE, BOX, PLANE };<br />
public:<br />
static const unsigned short type = NONE;<br />
<br />
virtual bool TestCollision(BVolume * volume)=0;<br />
<br />
};<br />
<br />

<br />
<br />
class BBox : public BVolume {<br />
public:<br />
static const unsigned short type = BOX;<br />
<br />
bool TestCollision(BVolume * volume) { return Collision< volume -> type >(volume); }<br />
<br />
template< unsigned short type > bool Collision(BVolume * volume) { return false; }<br />
<br />
template< > bool Collision< BOX >(BVolume * box) { return BoxCollision(static_cast< BBox * >(box)); }<br />
template< > bool Collision< SPHERE >(BVolume * sphere) { return SphereCollision(static_cast< BSphere * >(sphere)); }<br />
<br />
bool BoxCollision(BBox * box) { return true; } //For Testing That Code<br />
bool SphereCollision(BSphere * box) { return true; } //For Testing That Code (BSphere is for testing too)<br />
<br />
<br />
};<br />
<br />

<br />
<br />
BBox b1, b2;<br />
<br />
bool Collided() {<br />
<br />
return b1.TestCollision(&b2);<br />
<br />
}<br />
<br />
if(Collided()) std::cout << "Collided";<br />
else std::cout << "Not Collided";<br />
<br />

the code above outputs "Not Collided"

I found the problem but i don't know how to solve it.

Problem:

volume->type in BBox::TestCollision is NONE (it needs to be BOX or SPHERE here) because static is a Compile Time "Thing". I need something Run Time "Thing".

What can i do? Please Help me with that problem!

Thanks,
Kasya

Why don't you use a virtual method, for instance getType(), instead of a const?
Smile | :)

KasyaMafia4-Jan-09 4:33

4-Jan-09 4:33

please tell me how? Like that:

virtual const unsigned short getType() { return BOX; }

It doesn't work i tested it.

If you mean another thing please tell me.

Thanks,
Kasya

This works for me:

class BVolume {
public:
enum { NONE = 0, SPHERE, BOX, PLANE };
	static const unsigned short type = NONE;

virtual bool TestCollision(BVolume * volume)=0;
virtual const unsigned int getType(){ return NONE;}

};

class BBox : public BVolume {
public:
static const unsigned short type = BOX;

bool TestCollision(BVolume * volume) { return Collision< volume -> type >(volume); }

template< unsigned short type > bool Collision(BVolume * volume) { return false; }


bool BoxCollision(BBox * box) { return true; } //For Testing That Code
virtual const unsigned int getType(){ return BOX;}

};


void main()
{
	BBox b1, b2;
	BVolume *pv1 = &b1;
	if ( pv1->getType() == BVolume::BOX) cout << "is a box" << endl;
}

i get error when using this:

bool TestCollision(BoundingVolume * volume) { return Collision< volume->getType() >(volume); }

Error:

error C2975: 'type' : invalid template argument for 'BoundingBox::Collision', expected compile-time constant expression

Why don't you exploit polymorphism instead of using template methods?

You mean overload the functions. Then why i need BVolume Class here in my code. If i can do it with template please tell me how.

Thanks,

You need it because polymorphism works this way. I actually don't see how templates can do the job, in your scenario.

Devise a system of commands that the microcontroller sends to the C++ program, and then have the program carry out the commands.

What specifically is your question? What is it that you want to find out?

Wow. You're basically asking how to program for the Windows platform.

There's no simple answer, it's a long process of research and learning.

As for which headers and libraries to use, the answer is "all of them."

Why not start researching some of these things with MSDN and Google, and then come back when you have specific questions about a particular thing.

Have you ever written a Windows program before? Do you know how to use Visual Studio?

Everyone was a noob at one point.

You might want to start with a book like this one:

I wish you lots of luck with your project, and welcome to the world of Windows programming!

Have a look at Codeproject Articles[^] regarding Serial port communication. You can find a lot of samples which handles serial port communication. Now the rest is to interpret the read data accordingly and do the intended operations. If you have more doubts about "how to do x", then please be specific.

Regards,
Jijo.

In your serial communication class you must have an eventhandler which is called by interrupt service and sending custom messages to your mainfrm application class. Handle this custom messages to convert them to windows messages.
