Trying to intercept Hyperlink dialog in edit mode CHtmlEditCtrl (WebBrowser control)

Try to define your strings in the yourapp.rc file Smile | :)

STRINGTABLE

    IDC_CMD_BUTTON_2 "This is the tooltip for button 2" // the same IDC_CMD_BUTTON_2 ordered to the button 2
    IDC_CMD_BUTTON_3 "This is the tooltip for button 3" // the same IDC_CMD_BUTTON_3 ordered to the button 3
    IDC_CMD_BUTTON_4 "This is the tooltip for button 4" // the same IDC_CMD_BUTTON_4 ordered to the button 4

Hi,

I have an application that uses CHtmlEditCtrl for some WYSIWYG HTML editing. All is good, except that I need to add some custom protocols to the Hyperlink editor dialog. I have tried a couple of ways of doing this, but have some up against problem with each. The things tried are:

1. Open our own dialog in place of the in-built: ok if adding a new link, but when editing a link don't get the default behaviours of selecting the whole link text if caret is in middle of link, and can't get the existing URL to edit.

2. Catch the creation of the dialog with a hook, so I can fiddle with its controls: no good - the hook doesn't get entered on creation of the dialog

I would prefer option 1 if I can:
a. get it to select the whole link text (may not be required, but better if it can)
b. retrieve the URL of the selected link

Does anyone have any ideas? Has anyone managed to successfully intercept the Hyperlink dialog in any way?

Thanks,

Paul.

Hi can any one please tell me how to convert one DWORD
to CString in VC++. (Both in Hex and decimal Formate)

Eugen Podsypalnikov17-Mar-10 1:00

Try it

DWORD dwTest(1234);
 
CString cszTest;
cszTest.Format(_T("DEC: %u; HEX: 0x%08x"), dwTest, dwTest);

virtual void BeHappy() = 0;

Hi Thanks for your kind reply..

I tried the way, but i guess it is showing me the memory location

DWORD dwTest(0xFFFFFFFF);
CString cszTest;
cszTest.Format(_T("DEC: %u HEX: 0x%08x"), dwTest, dwTest);
cout<<cszTest;

I am getting a output of
0036AA20

problem may be with cout and unicode. To ensure it, try with _tprintf(_T("%s", cszTest));

I don't know whether there is any unicode version of cout.

how can i get the path of a specific application?

If the project setting is UNICODE, you may have to use as follows:
wcout << (LPCTSTR)cszTest;
Give it a try if cout is not working Smile | :)

hi i need to gain the path of adobe acrobat but i don't know how.
i know that i can use registery but i don't know the adobe acrobat's key in registery.
can you help me?
thanks.

Yes, I think so,

Unanticipated behavior from overloaded cast operator... [modified]

Mike the Red16-Mar-10 23:01

Re: Unanticipated behavior from overloaded cast operator...

16-Mar-10 23:01

The code:

class testClass {
public:
	testClass() {	m_buff = new BYTE[20]; 
			memcpy(m_buff, "0123456789", 10); 
	};
	~testClass() { delete m_buff; };

	operator LPBYTE () { return m_buff; };

	void show() {
		cout << "m_buff = " << (__int64) (void *) m_buff << "\n\t"; // Show address of m_buff
		for (int i = 0; i < 10; i++) // Show contents of m_buff
			cout << m_buff[i];
		cout << "\n";
	};
private:
	LPBYTE m_buff;
};

int main(int argc, char * argv[])
{
	testClass * foo = new testClass();
	foo->show();
	cout << "foo = " << (__int64) (void *) foo << "\n"; // Show address of foo
	cout << "(LPBYTE) foo = " << (__int64) (void *) ( (LPBYTE) foo ) << "\n\t"; // Show address of cast (LPBYTE) foo
	for (int i = 0; i < 10; i++) // Show contents of cast (LPBYTE) foo
		cout << ((LPBYTE) foo)[i];
	
	cout << "\n";
	delete foo;
	return true;
};

And some output:

m_buff = 9180016
	0123456789
foo = 9179968
(LPBYTE) foo = 9179968
	-garbage-

I was expecting to see:

m_buff = 9180016
	0123456789
foo = 9179968
(LPBYTE) foo = 9180016 // same address as m_buff
	0123456789

What am I missing ?

I know I could accomplish something similar with a member function returning the address of m_buff, but in my ever more ridiculous quest to learn more aspects of C++, I wanted to try this operator overloading bit....

As always, any guidance you can offer is greatly appreciated.

My apologies for using __int64... I know it's Microsoft specific, but I use what I've got.

Don't you mean (LPBYTE)*foo since foo is a pointer?

PS: You might want to add copy constructor and assignment operator to your class. Law of the Big Two, classes that handle memory/resources usually need a copy constructor and an assignment operator.

Thanks, Moak! I didn't understand you at first, but that's exactly the problem.

I didn't understand your post until Pallini gave a longer explanation of this.

Thanks for your help!!!

PS:
Thanks for the suggestion about the Big Two, but I don't think so in this case.

The idea behind the class is for it to always behave as a dynamically-allocated LPBYTE, but somtimes point to a MMF, when the buffer is larger than a certain threshold.
In both cases (true LPBYTE or LPBYTE pointing to an MMF), the standard memory functions (memcpy, memset, etc.) are appropriate.
(Which is why I want the cast to point to the same place as the member pointer m_buff.)

Mike the Red wrote:

The address of the class and the one of the m_buff variable (i.e. &m_buff) are the same.
On the other hand, the address of the class differs from that of the memory buffer (i.e. m_buff).

To verify, add the following line to the show method:

cout << "&m_buff = " << (__int64) (void *) &m_buff << "\n\t"; // Show the REAL address of m_buff

(that happens because of dynamic memory allocation).

Re: Wait.. my overloaded operator isn't being called....

16-Mar-10 23:59

I changed the operator function to:

operator LPBYTE () { cout << "Inside operator.\n"; return &this->m_buff[0]; };

...but Inside operator. never appears in the output.

If I explicitly use foo->operator LPBYTE() then Inside operator. appears in the output but not if I use an explicit cast (LPBYTE) foo.

Any ideas on that one ?

17-Mar-10 0:09

Sorry, I misunderstood the original question (I missed the cast operator overloading... Blush | :O

).
You overloaded correctly it, but you should apply it to an instance of the class not to a pointer to, modify from

for (int i = 0; i < 10; i++) // Show contents of cast (LPBYTE) foo
		cout << ((LPBYTE) foo)[i];

for (int i = 0; i < 10; i++) // Show contents of cast (LPBYTE) foo
		cout << ((LPBYTE) (*foo))[i];
