C / C++ / MFC

3-Mar-06 15:02

Hello Guys,
I've an old Win32 application, which is written in C. The problem is that for some reason, we need to convert it to MFC.

I'd prefer is a separate application that can swallow and show instances of Win32-App and provide the interface. Is it possible?

I'd love to know.

Did u mean u want to run another application from the old one?
If so the functions like ShellExecute() and CreateProcess() will help u.

Nave,
Thanks for replying. Let me clarify:

We've a Win32 application with source code. I want to create a new MFC application. Now I want to run Win32-app in way that it only appears in my MFC application (not on taskbar, not on desktop) but *inside* my MFC application. [That is the MFC-app becomes the parent of the Win32-app]

This will allow me to keep the Win32-app intact, while the outer-frame will be in MFC, which offcourse, I'll customize way more easily than Win32.

ShellExecute() I think won't help as it still create a new instance on the desktop. I can still pass the handle to my MFC application but that will only relay messages to my MFC app.

I know converting Win32-app to ActiveX looks like a good idea. I'm here to explore other options.

For your 'ShellExecute()' will work. If you don't wanna to display the process(on desktop/taskbar), just put last parameter of the fuction as 'SW_HIDE'(0).

Well ! Try it...

Top margin in CEditView

It's clear how to set right and left margins in an instance of CEditView. Is there a way to effectively set a top margin?

In the PARAFORMAT2 Structure there is a member called dySpaceBefore. You will need to build a function to call this member using the dwMask member. The value must always be > than or = 0. The Size of the spacing is in twips. You may be able to set up something similar in the PARAFORMAT structure if you are using later versions of Visual C++. Go to MDN.COM and do a search for PARAFORMAT OR PARAFORMAT2. I think there is an example there somewhere..??

sorry. I ment msdn.com not mdn.com also, if you ar running v.s. 6.0 PARAFORMAT may be the structure to use...

Much thanks, I'll take a look.

I just looked. Two problems occur to me; first, this is for a CRichEditView, not a CEditView. The other problem is that this would allow control of the space above a paragraph--- not the space above the page. Perhaps I'm missing something?

MFC & inner class question...

5-Mar-06 6:55

For those with the same problem, a tentative answer is to set the rectangle in the CEdit control:

void CPGNTextView::SetTopMargin()<br />
{<br />
	CEdit &theEdit = GetEditCtrl();<br />
	CRect r;<br />
	theEdit.GetRect(&r);<br />
	TRACE("t=%d l=%d b=%d r=%d\n",r.top,r.left,r.bottom,r.right);<br />
	r.top = TOP_MARGIN;<br />
	theEdit.SetRect(&r);<br />
	TRACE("t=%d l=%d b=%d r=%d\n",r.top,r.left,r.bottom,r.right);<br />
}

And then to do it again in WM_SIZE and WM_SETFONT handlers. Seems like overkill, but the CEdit control loses this information every chance it gets so you just have to help it along so to speak.

Is there a way I can do something like this:

<br />
class MyClass<br />
{<br />
...<br />
private:<br />
class MyInnerClass: public CWnd<br />
{<br />
...<br />
//{{AFX_MSG(MyInnerClass)<br />
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);<br />
afx_msg void OnShowWindow(BOOL bShow, UINT nStatus);<br />
//}}AFX_MSG<br />
...<br />
};<br />
...<br />
};<br />

??
I've been trying for a while, and the code doesn't even compile (if I declare the class outside the first one, everything works OK, but I want the class to be inner). I suspect it's a matter of names for the message maps, but can't figure out the right one...
Thanks!
Alberto.

Why do you feel the inner class is necessary?

I would probably have done this instead:

class MyInnerClass: public CWnd<br />
{<br />
...<br />
//{{AFX_MSG(MyInnerClass)<br />
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);<br />
afx_msg void OnShowWindow(BOOL bShow, UINT nStatus);<br />
//}}AFX_MSG<br />
...<br />
};<br />
<br />
class MyClass<br />
{<br />
...<br />
private:<br />
MyInnerClass* m_InnerClass;<br />
...<br />
};

And avoid the entire problem.

It's what I've done, but I feel the inner class is necessary for preventing unnecesary access to it.
I just wanted it to be sort of "private", and it seemed to me it was the best way (ok, i admit it...I'm a java programmer).

Thanks for the answer (sorry for my english)...

If you really want to hide the internals of your class, then
make a forward declaration like this:

class MyInnerClass;

then use it privately in some other class:

class SomeOtherClass
{
...
private:
MyInnerClass* m_MyInnerClass;
...
};

and then declare the MyInnerClass in the source file along with its implementation as the same source file as SomeOtherClass and only SomeOtherClass will ever be able to actually 'use' the MyInnerClass.

Or, just declaring the pointer to it like the original example, that pretty much prevents ANYTHING else from using the MyInnerClass anyhow.

have you tried:
