but in my case, i would like to intercept from any webpage browsed....e.g. in DWebBrowserEvents2, a dispid DISP_NAVIGATECOMPLETE2 is used to intercept the IE's control whenever the browser finish navigate certain page...
as for my page, i would like the user to click any image from any website, intercept the control and get the image's PIDL for my bho usage.....using this interface IHTMLImgEvents2 http://msdn.microsoft.com/workshop/browser/mshtml/reference/events/htmlimgevents2/htmlimgevents2.asp
again, correct me if i'm wrong in any of these understanding

I'm trying to extend a CEdit ctrl in WTL. But i havn't found out how to paint in the control after the default paint mechanism.
Is there a way to invoke the default paint mechanism while handling WM_PAINT, something like CEdit::OnPaint(...)?

This is simplified version of what I am doing but still shows the issue : The Copy Ctor is being called by the for_each algorithm. Whilst in this case it isn't an issue, but in my live app it is. Why is the copy ctor being called and can I prevent it..?
class ProcessVector
{
public:
ProcessVector(const ProcessVector &rhs)
{
cout << "copy ctor" << endl;
}
ProcessVector()
{
cout << "ctor" << endl;
}
~ProcessVector()
{
cout << "dtor" << endl;
}
void operator ()(int i)
{
cout << i << endl;
}
};
int main(int argc, char* argv[])
{
std::vector <int> test;
for (int i = 0 ; i< 5; i++)
test.push_back(i);
for_each(test.begin(), test.end() , ProcessVector() );
return 0;
}gives the following output
ctor
0
1
2
3
4
copy ctor

It's by design - the C++ Standard specifies that the function object is passed by value, not by reference and that a *copy* of the function object is returned by for_each. You'll have to work round whatever problems this causes you.

Easy, add an extra level of redirection to manage the lifetime. This issue is described as Stateful Predicates in the book Exceptional C++
#include <algorithm>
#include <vector>
#include <iostream>
using namespace std;
class ProcessVector
{
public:
ProcessVector()
{
cout << "ctor" << endl;
}
~ProcessVector()
{
cout << "dtor" << endl;
}
void operator ()(int i)
{
cout << i << endl;
}
ProcessVector(const ProcessVector &rhs)
{
cout << "copy ctor" << endl;
}
};
class ProcessVectorIndirect
{
public:
ProcessVectorIndirect(ProcessVector* process)
: pProcess(process)
{
}
void operator ()(int i)
{
(*pProcess)(i);
}
private:
ProcessVector* pProcess;
};
int main(int argc, char* argv[])
{
std::vector <int> test;
for (int i = 0 ; i< 5; i++)
test.push_back(i);
ProcessVector vect;
for_each(test.begin(), test.end() , ProcessVectorIndirect(&vect) );
return 0;
}

Hi,
I want two atl controls to communicate with each other. what area of COM / ATL should i be looking into. Connection points or something?
I want the second control to list the first control in a datasource property.
Thanks

hi,
I tried to catch an event in vb script which is fired from a com object. It works in vb but not in vbscript!
interface just like this
dispinterface _INotiEvents
{
properties:
methods:
[id(2), helpstring("method Notify")] HRESULT Notify();
};
script:
Sub objInstance_Notify
alert ( "Event" )
End Sub
Something I have to care about, so that vbscript is able to catch the event?
thx and greets

Did you use "source" attribude in IDL when were declaring the coclass?
My site - Body Jewelry

|

yes it looks like this:
coclass Noti
{
[default] interface INoti;
[default, source] dispinterface _INotiEvents;
}
somewhere a sample where events are catched in script?
thx

Hello People,
I'm trying to design some kind of windows form app. which I can also use as a plug-in in IE. just like Acrobat reader for instance. I'm a total newbie and I don't even know in which direction to think, so every comment is welcome.
Thanks

Hi,
I'm trying to load from a resource or file a bitmap, 16x16 and display it in my ATL control. so far i have been unsuccessfull. this is the code i have used.
HRESULT CIBPPDatabase::OnDraw(ATL_DRAWINFO& di)
{
RECT& rc = *(RECT*)di.prcBounds;
HDC hdc = di.hdcDraw;
HBITMAP hNoteBmp;
HDC hNoteDC;
hNoteDC = CreateCompatibleDC(hdc);
hNoteBmp = (HBITMAP)LoadImage(NULL, "C:/Connec.bmp",IMAGE_BITMAP,
0,0, LR_LOADFROMFILE );
if (hNoteBmp == NULL)
MessageBox("NULL");
SelectObject(hNoteDC, hNoteBmp);
SetBkMode(hNoteDC, TRANSPARENT);
BitBlt(hdc, 0, 0, 32,
32, hNoteDC, 0, 0, SRCCOPY);
DeleteObject(hNoteBmp);
DeleteDC(hNoteDC);
return S_OK;
}
Any help would be appreciated.
Thanks
Gary

1. You're blitting to (0,0) in the target DC, which is wrong. That should be (rc.left, rc.top)
2. Is the size 16x16 or 32x32? Make sure you get the size right.
3. You're leaking a bitmap handle every time through, you need to select hNoteBmp out of hNoteDC before deleting hNoteBmp and hNoteDC.

Hi Michael,
Well my code now reads as follows, but i still ain't got no bitmap to display on my control.
HRESULT CIBPPDatabase::OnDraw(ATL_DRAWINFO& di)
{
RECT& rc = *(RECT*)di.prcBounds;
HDC hdc = di.hdcDraw;
HBITMAP hNoteBmp;
HDC hNoteDC;
hNoteDC = CreateCompatibleDC(hdc);
hNoteBmp = (HBITMAP)LoadImage(NULL, "C:/NEW.bmp",IMAGE_BITMAP,
0,0, LR_LOADFROMFILE );
if (hNoteBmp == NULL)
MessageBox("NULL");
SelectObject(hNoteDC, hNoteBmp);
//SetBkMode(hNoteDC, TRANSPARENT);
BitBlt(hdc, rc.left, rc.top, 32,
32, hNoteDC, 0, 0, SRCCOPY);
DeleteDC(hNoteDC);
DeleteObject(hNoteBmp);
return S_OK;
}
Wonder what is happening.
Thanks
Gary

I believe you have to supply the bitmap's dimensions in the LoadImage() and they should be correct (get them from your bitmap properties).
Igor.

I've done some extra scratching about and came across a variable in the constructor called m_bWindowed = TRUE;
If i change that to m_bWindowed = FALSE then my bitmap is loaded and displayed correctly.
only issue now is; my control is no visible at designtime, good but also at runtime.
I'll keep poking around, i have a feeling it could be something i selected in the wizard when i added an ATL object to my project. Thing is you should be able to reverse that setting some how.
Thanks
Gary

Hi All,
Well i've fixed the problem; which wasn't really a problem.
It seems that the activex test control container does not so the control the way i thought it should.
i.e it displays textout on your atl control, but not the graphic? Huh?
So i tested it in a project and the graphic appeared for design time, and disappeared at runtime. fabulous.
Thanks to everyone who helped, it was appreciated.
Thanks
Gary

Hallo,
I’m writing a Winlogon/Notify packet. I have therefore written a dll and made the necessaries registry entries. The communication between winlogon.exe and my dll is ok.
I’m unfortunalty facing a curious problem trying to work with the member variables from the PWLX_NOTIFICATION_INFO object passed from WinLogon.exe
Follow some code lines.
<br />
void __stdcall MyLogOn(PWLX_NOTIFICATION_INFO pInfo)<br />
{<br />
if((pInfo!=NULL)&&(pInfo->Domain != NULL))<br />
{<br />
size_t iSize;<br />
char *cDomain = NULL;<br />
iSize = wcstombs(0, pInfo->Domain,0);
cDomain = new char[iSize];<br />
cDomain[iSize] = NULL;<br />
<br />
wcstombs(cDomain, pInfo->Domain, iSize);<br />
} <br />
}<br />
<br />
What is wrong with my code?
Thanks in advance for helping.

From http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_wcstombs.asp[^]
If the mbstr argument is NULL, wcstombs returns the required size of the destination string. If wcstombs encounters a wide character it cannot be convert to a multibyte character, it returns –1 cast to type size_t.
Could it be such a character in your input string? Are you also 100% sure that pInfo->Domain is a valid string?

I have a .NET class which provides COM Interop. How does an ATL App consume this .NET class?
|
|

Not sure what is the problem. You do it as any other COM object.

Hallo,
How please to get the length of a PWSTR variable.
I unfortunatly try
<br />
size_t size = 0;<br />
if(pInfo->Domain!=NULL)<br />

size = wcstombs(0, pInfo->Domain, 0);<br />
}<br />
I want to convert the UserName and the Domain from a WLX_NOTIFICATION_INFO variable to Char.
<br />
typedef struct _WLX_NOTIFICATION_INFO { <br />
ULONG Size; <br />
ULONG Flags; <br />
PWSTR UserName; <br />
PWSTR Domain; <br />
PWSTR WindowStation; <br />
HANDLE hToken; <br />
HDESK hDesktop; <br />
PFNMSGECALLBACK pStatusCallback;<br />
} WLX_NOTIFICATION_INFO, *PWLX_NOTIFICATION_INFO;<br />
thanks a lot for your help
