Hi,
I'm a novice MFC programmer and am trying to give myself a crash course by programming a simple web application. Basically, I'm trying to create a program to extract information from web pages. I've accomplished this by using the MS web browser control and MSHTML.
I'm really downloading web pages in the background so there's no need for me to download the included images. I know it's possible to turn off image downloading in the WB control, but the only explanations I've found on the MSDN site are very unclear. They discuss modifying IDispatch::Invoke to handle DISPID_AMBIENT_DLCONTROL.
Can anyone out there help explain how to do this a little more clearly? My current project has a CWebbrowser class being used by a Dialog box and I don't see where I'm supposed to make these IDispatch modifications.

Sirs,
do you have information, eventually links of how this key works?

I have a class called CToolBarTab which is derived from CTabCtrl. The idea is that you 'attach' it to a dialogbar, and it stretches to fit it. how can i do this? i tried calling GetClientRect on the dialogbar passed in my Create function, but it didn't work...
thanks in advance!

I was wondering the correct way to tell if a dialog has focus or not. Anyone have a sample if statement handy?
|
|

use CWnd::GetFocus
It returns the CWnd* of the window that has focus
If you are not using MFC try using a combination of GetForegroundWindow and GetFocus [both are API calls]

Dialogs usually do not have the focus. Focus belongs to the controls on the dialog - edits, buttons, etc.
Why do you need to know this?

I writed regular dll in vc++ for delphi.
It works in vc client program but in delphi it performs illegal ... and shut down when it trys to send parameter to the function.
the function declared in the dll so :
extern "C" __declspec(dllexport) int Reg1(int pc)
====================================================
Please help !!!!

You probably need to add __stdcall to the prototype. Right now I'm using a Delphi DLL from C and the exported functions use the __stdcall convention, so it's probably the same going the other way (C used in Delphi).

Thank you !
Where exactly need I to add _stdcall ?
Manny thanks
|
|
|
|
|
I declared the function in my dll so :
extern "C" __declspec(dllexport) BOOL _stdcall func(int num);
and now the Delphi client program can not connect to it at all !
What can I to do ??? Please help !!!
|
|
|
|
|
Exported __stdcall functions have their names mangled. That's probably why Delphi program 'can't connect'.
I have zero experience with Delphi - are you using LoadLibrary/GetProcAddress before calling function from DLL? Or Delphi does this for you?

hi,
i have a loop and in it it connects to a http site with CInternetConnection, but the dialog does not update util it has finished doing everything, i overcame this by addeing some CDialog::RedrawWindow(); in, but still its doesn't process any clicks on buttons or anything, it just redraws the window with my updated status, so is there a way to fix this? delphi has a processMessages() proceduce, is there something simular in MFC VC++ ?
thanks for any hepl you can provide.
p.s great site
muz.

use a worker thread
Read Joe Newcomer's article on worker threads
that should get you started

How can I make a flat window, I mean there is no separate line between the menu and tool bar,
Thank you

I have three classes the are dependant on each other
ex:
#include "First.h"
class First {
Second* psecond;
public:
First();
~First();
void AttachSecond(Second* second);
};
#include "Third.h"
class Second {
Third* pthird;
public:
Second();
~Second();
void AttachThird(Third* third);
};
#include "First.h"
class Third {
First* pfirst;
public:
Third();
~Third();
void AttachFirst(First* First);
};
When I do the includes for each class, VC gives me
undeclared identifier errors on any reference to the included class.
Any Ideas or is it too cryptic?

What I would do is use forward declarations. In each class' header I would do the old :
class CSecond;
or
class CThird;
or whatever class is referenced in that header. I would not include the other class header there. I would put the includes of the other headers in the source code module of the class that needs it.

It worked. Thank you.

Hmmm - that first include should be #include "second.h", but maybe thats a typo.
Have you tried using forward declarations instead? If you are only using pointers to the classes, this should work:
class Second;
class First {
Second* psecond;
public:
First();
~First();
void AttachSecond(Second* second);
};
|

I don't quite understand the example, but I'll assume you have three different .h files, each .h with one class.
based on what I said, It seems that your first class should include the second class header, like this:
/*instead of: #include "First.h" */
#include "Second.h"
class First {
...
...

Dear smart programmers:
Could someone help me. I have ListCtrl of 8 colums and I need put checkboxes in Col4, Col5 and Col8. Thank you in advance,
Mats

Use LVS_EX_SUBITEMIMAGES extended style, create an image list containing checked and unchecked boxes. If you want users to switch between checked/unchecked states with the mouse, you'll have to handle WM_LBUTTONDOWN as well. CListCtrl::HitTest will check if click was inside subitem image.

1. how can create items in CListCtrl with different font color for each item?
2. how can i add a Progress Bar to a status bar?
thanks a lot

For 1., I think you'll want to look at subclassing your own CListCtrl, setting the 'Owner draw fixed' style in the resorce editor. Then you can override the CListCtrl::DrawItem method and use ::SetTextColor and ::SetBkColor to change the colors on a per item basis. (Er, assuming you are using DrawText(lpDrawItemStruct->hDC, ...))
There should be lots of articles here on the site with more info on this type of stuff.

(1) - If all that you need is different colors, use custom draw (not owner-draw). There's an article about that right here on CodeProject, in the ListCtrl section.
