Hi,
I'm new to Win32 programming, and I have to add dialog resource and management in a static lib in order to be used by other application.
I've added dialog resource in lib project and include all ATL stuff inside lib.
Everything compile ok but ATL create dialog function failed with 1812 error, complaining that no resource are present in exe image.

The base application is a classic win32 project without MFC.

What should I check ?

Thanks

Web Browser Control

The tab key doesnt work in Web Browser Control. The following code is supposed to resolve it. However the keydown message is not fired at all. There is another code below this one which is supposed to resolve even this problem but I dont know where to place it.

Code 1:

LRESULT CMyClass::OnKeydown(UINT uMsg, WPARAM wParam, LPARAM lParam,
BOOL& bHandled)
{
// m_spWebBrowser is a data member of type IWebBrowser2.
// Using CComQIPtr in this way queries m_spWebBrowser
// for the IOleInPlaceActiveObject interface which is
// then stored in the pIOIPAO variable.
//
CComQIPtr<ioleinplaceactiveobject,
&iid_ioleinplaceactiveobject=""> pIOIPAO(m_spWebBrowser);

HRESULT hr = S_FALSE;

if (pIOIPAO)
{
MSG msg;
msg.message = uMsg;
msg.wParam = wParam;
msg.lParam = lParam;

hr = pIOIPAO->TranslateAccelerator(&msg);
}

return hr;

Code 2:

while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);

// Send all keyboard messages to the window of your
// application. hwndApp is the window handle of
// your application.
//
if (msg.message >= WM_KEYFIRST && msg.message <= WM_KEYLAST)
::SendMessage(hwndApp, msg.message, msg.wParam, msg.lParam);

DispatchMessage(&msg);
}

hi, i'm currently working on a bho that works tight with image....

as event disp intercepter...i found we need to connect to DIID_DWebBrowserEvents2 in order to intercept event handler under it, but where can i connect to in order to intercept event handler fired by an image events??

thx a lot

Re: PostPaint in WTL::CEdit

23-Feb-05 20:27

hmmmh, this article work wif onclick event, for element which created by the system itself...tat's wad i understand from the coding....correct me if i'm wrong....=.="

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 Smile | :)

ur help is appreciated so much Smile | :)

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(...)?

Call DefWindowProc() as the first thing in your handler.

for_each calls copy ctor on functor?

Malcolm Smart21-Feb-05 22:56

Malcolm Smart

21-Feb-05 22:56

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
dtor
dtor

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;
}

Event is not catched in script

21-Feb-05 16:48

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?

Re: Event is not catched in script

yes it looks like this:
coclass Noti
{
[default] interface INoti;
[default, source] dispinterface _INotiEvents;
}

somewhere a sample where events are catched in script?

thx

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).

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
