Hi.

Is it possible to incorporate a link in an edit view? For example, let say the program displays this line:

-----
Here is a link to Google: www.google.com
-----

Okay. I would like it such that the user can click on part of the line "www...com" and the program can do things such as open a the default web browser or open a dialog box. What is the best way to incorporate a link type of feature in a CEditView?

Thanks,
Kuphryn

I don't think this is possible with CEditView (at least without alot of work.) However, CRichEditView can do this. I can't remember the exact flag you have to set, but I'm pretty sure there is one.

Thanks.

I was afraid of this even before I posted. I have put a lot of work into the program using CEditView. I am not sure how much time I will take going from CEditView to CRichEditView.

You could try putting a static control on top of the edit control and putting the link text in the static control. And handle the mouse click.

I will look at adding a static control.

I don't know how you can do it in a CEditView. In a CRichEditView you need to process the EN_LINK message.

Hi,

I'm looking for the online tutorial and sample code about how to implement threading through unix pipe facility instead of pThread. (in C++ or C programming)

Does anyone know where i can find a good resource in these areas? Does anyone know what is pipe and how to use it???

Thanks!!!

I suggest that you search for some unix programming related sites

From MoveWindow Help:

For a top-level window, the position and dimensions are relative to the upper-left corner of the screen. For a child window, they are relative to the upper-left corner of the parent window's client area.

Overriding = operator

I want to have an assignment operator in a class that I have several classes derived from. I want to be able to call the assignment operator using an object defined as a pointer to the base class but have it execute the code in the proper derived class.

I don't know if I explained it very well so here's a little bit of code:

CElement* pTempElement;
pTempElement = pElement;

where pElement is a pointer to a class that was derived from the CElement base class.

My goal is to be able to get the data from pElement to pTempElement but not share the memory address. If there's an easier way than I'm working on, that's fine too. Probably a stupid question but I've always had a bit of a mental block when it comes to pointers.

Override new operator instead?

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

You need to dereference the objects;

CElement* pTempElement;
*pTempElement = *pElement;

Using operator= is not a good idea, since the version for the base class will be used instead of that of the actual type pointed to by pElement. The standard idiom to handle this situation (which is fairly common) is to define a virtual function clone just like this:

class CElement
{
  ...
  virtual CElement* clone()=0;
};

Then in every derived class you just write:

class CDerivedElement
{
  ...
  virtual CElement* clone()
  {
    return new CDerivedElement(*this);
  }
}

so that your program can copy objects like this:

CElement* pTempElement;
pTempElement=pElement->clone();

Remember to declare ~CElement as virtual. Good luck.

I have a MDI application that the CRichEditView (from which I can get the CRichEditCtrl object). How do I insert lines of text programmatically? And can I do it line by line?

hey, i have a hook procedure which catches the creation of menu windows... but it only works sometimes and for some menus

for example, the right-click menu in the caption bar always gets caught, and the top menus sometimes get caught

is there a way to catch the creation of ALL menus, like an example or something?

thanks
