Have you tried SystemParametersInfo(SPI_SETDESKWALLPAPER, ...)?

Hi All,
I have developed the project in ATL in which I am getting events from the browser window through Invoke() function of the IDispatch interface.
And my question is that I want to get Mouse Click event with the element id on which event has been fired.How can I do that?
I tried below code to do the same but I m not getting success.
STDMETHODIMP CSimpleTab::Invoke(DISPID dispIdMember, REFIID riid, LCID lcid, WORD wFlags,
DISPPARAMS* pDispParams, VARIANT* pVarResult,
EXCEPINFO* pExcepInfo, UINT* puArgErr)
{
switch (dispIdMember)
{
case DISPID_HTMLELEMENTEVENTS2_ONMOUSEDOWN:
{
CComVariant dis_event;
dis_event = (CSimpleTab *)(this);
IDispatch *lpDispatch = pVarResult->pdispVal;
IHTMLEventObj * eventObj;
HRESULT hr = lpDispatch->QueryInterface(IID_IHTMLEventObj,(void **)&eventObj);
IHTMLElement * element;
eventObj->get_srcElement(&element);
}
}
}
in above code I m getting null in to the pVarResult->pdispVal parameter.
Do you have any idea why does this happen?
Thanks in Advance.
Ashish Bhatt,
Indianic,Ahmedabad.

You've already posted your query in the ATL forum, which is more appropriate. Just have patience and wait for replies.

What's the correlation between getting stuck at work and posting a question on the wrong forum?

On the event handler get the event from the html document,
IHTMLDocument2::get_parentWindow(); the window that received the event
IHTMLWindow2::get_event(); get the event object from window
IHTMLEventObj::get_srcElement(); get the element which fired the event
IHTMLElement::get_id(); get the id of the element.
find the source code for this in MFC src directory, in the file dlgdhtml.cpp in the function CDHtmlEventSink::FindDHtmlEventEntry which is called from CDHtmlEventSink::Invoke();
or go for CDHTMLDialog, very easy to use, you just want to add the message handler
DHTML_EVENT_ONMOUSEDOWN(elemName, memberFxn);
I used some code from the CDHtmlDialog and modified for my requirement some months before, as CDHtmlDialog cannot handle event when more than one frame (IFrame, frame) exists in the main html page.

Hi gang,
my application deals with a lot of windows, popup or mdi, having their own wndproc depending on what they have to do...
I'm searching a way to have a topmost popup window limited to the application (ie not top most for other apps).
I've tried to use the SetWindowPos( ... HWN_TOP ) in the WM_WINDOWPOSCHANGED of WndProcs but it gives to many WM_PAINT...
VC6, Win32API, no ATL neither MFC.
Some tips?
Thanks,
PS:i searched the archive w/o success (maybe my fault), sorry if the answer has already been posted

If you set the main window to the be parent of your child windows, they will always appear above the main window.

Have you tried here? Does this help?

I have a question about the sample "chap_09\ZFXInput" of the book "3D Game Engine Programming".
I used the VC++2005 to compile the sample "chap_09\ZFXInput".
But it appeared one error as below:
Error 1 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int e:\data1\akira recent study\3d game engine programming\chapter data\chap_09\zfxinput\zfxdi\zfxjoystick.cpp 12
How do I solve this problem?
// File: ZFXJoystick.cpp
#include <windows.h> // type definitions
#include "ZFXDI.h" // class definition
extern bool g_bLF;
// Yeah, evil callback stuff. Let's rock C++, let's rock!
ZFXJoystick *g_pThis=NULL;
CALLBACK gEnumJoyCallback(const DIDEVICEINSTANCE* pInst, void* pUserData);<======problem

The problem is that your gEnumJoyCallback declarations has no return value.
vc++ requires you to explicitly set one. you can fix this by using the return type void, what does in fact mean "no return value":
void CALLBACK gEnumJoyCallback(const DIDEVICEINSTANCE* pInst, void* pUserData);
Don't try it, just do it!

yes, Alexander already given the solution.
Apart from this, you can disable the warning with compiler option /wd4430. if you don't want to change the code.

Hi,
Currently I am working in project for Unicode support. I mean this is a project which is already developed in C++ (Using MS VC++ 6.0), which is not suppoting unicode currenty. Now I am working on this project and do the necessary changes to support for Unicode. I have gone though the web and found some tools to do this. The tools are 1) To Unicode and 1) Globalyzer.
It will be a great help if some can help to find if there is any other tools avilable for unicode conversion. Also let me know the Links/URL’s which talking about this converion and give me some reffernce (people who are) of UNICODE experts.
Thanks,
Nandu

Have you completely read Michael Kaplan's 9 step tutorial? I was expecting you to come back with specific questions. But you're asking the same thing after a while. Had you been reading through the links provided to you previously, you would have come back with specific questions.
