ATL comes with Visual C++.
There's nothing special about showing a second dialog, it's the same as the first one. Create a class for it, create an object of that class and call its DoModal()

I have created a simple mfc activex control which works in the activex control test container.
Now I have have created an stl program and use #import to pull in definitions of the control and a wrapper class.
Next I have a function:
HRESULT hr;
_DMysearch *pSearch;
const IID IID_DMysearch = { 0x2887adc2, 0xeba1, 0x4ca9, { 0xb3, 0x58, 0x15, 0xae, 0xf, 0xd2, 0xb9, 0x6a } };
const CLSID CLSID_mysearch = {0x4ae8deda, 0xee97, 0x47ee,{ 0x9c, 0xcc, 0xd, 0x1b, 0x4b, 0x99, 0x6b, 0x88}};
::CoInitialize(NULL);
hr = CoCreateInstance (CLSID_mysearch, // CLSID of coclass
NULL, // not used - aggregation
CLSCTX_INPROC_SERVER, // type of server
IID_Dmysearch, // IID of interface
(void**) &pSearch ); // Pointer to our interface pointer
if ( SUCCEEDED ( hr ) )
{
long res = pSearch->test();
}
else
{
// Couldn't create the COM object. hr holds the error code.
}
I get as far as pSearch->test() which is a simple long function with no parameters and I get an exception from com_dispatch_method.
any ideas?

I have created a ATL exe service and added a interface to it....
I registered it and run it.
But for somereason sometimes the atl service starts automatically on its own making multiple copies in the memory..
can any one explain why it happens ?
here is createservice that is called, i belive something is in here but not able to figure it out.
SC_HANDLE hService = ::CreateService(
hSCM, m_szServiceName, m_szServiceName,
SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS,
SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
szFilePath, NULL, NULL, _T("RPCSS\0"), NULL, NULL);
Thanx in advance.

The MFC CFormView is a view but using a dialog resource for UI, which makes modifying the UI layout very easy, I think this class is great(at least for me). But when shifted to WTL, I cannot find a class(or I missed?) like the CFormView. So anyone got a clue or has implemented such a class would mind to share with me?
I'm new in WTL(even in ), and I've searched this forum with keyword "FormView"/"Form View" but just got "no results". So if you think my question is stupid, please forgive me. ^_&
Thanks for any reply.

Sorry for my poor English.

You can create a app with a form view with the WTL appwizard but there is no FormView class, the view uses CDialogImpl

I've created a Connection Page (in the Data Source Object of my OLE DB Provider) to be displayed by the Data Link core component.
Now I'm trying to add a tab control on the page using CreateWindow with the WC_TABCONTROL class (being registered through InitCommonControlsEx(...).
But I can't get the Instance Handle needed by CreateWindow,
because
hInst = (HINSTANCE)::GetWindowLong(hwndParent, GWL_HINSTANCE);
always returns 0x0000000.
(I've received the hwndParent through the IPropertyPage::Activate Method, that's being called by the Data Link core component)
How can I get that Instance Handle? Or is there another way of using a tab control on my property page?

Hi All,
I have a COM component which supports outgoing interface IDataCallback,which calls OnDataChange event.
When client Get Connectionpoints and Call Advise for Server,i want to fire OnDataChange.Where should i Know that Client has called Advise so that i should send him OnDataChange callback,just to show that callback is working.
In normal working i am sending OnDataChange whenever data Changes in my server,but i want to send this first OnDataChange as soon as Client call Advise.
Where should i write the code for this?
Code for my server is like this:
class MyServer;
typedef IConnectionPointImpl <myserver,&iid_idatacallback,ccomdynamicunkarray> DataCallback;
class ATL_NO_VTABLE MyServer :
public IInterface1,
public IInterface2,
public IConnectionPointContainerImpl<myserver>,
public DataCallback,
public CComObjectRootEx<ccommultithreadmodel>
{
---
}
Thanks in advance
Tushar.

Because you're deriving from IConnectionPointContainerImpl, then it's doing all the hard work for you.
You might be able to provide your own implementation of Advise, but you'd need to make sure you called the templated implementation first, then fired the event (if successful). Don't know whether (a) this is possible or (b) it's allowed, since you're effectively firing an event before Advise has completed, so I don't know if there's COM runtime magic involved.

Hi, i need an ADDin for Word 2000 ( XP and 2003 too) that has an dialog box
like a ATL Composite Control ( VC 7.1).
The problem is when this control is inserted in the Word (insert object) and lost focus,the dialog disapear (seems like the WM_PAINT don´t be triggered).
The control draws it self only when i "double click" the control.
I read some articles that this behavior is because the Word Container
don´t give us an Window to draw when the control is without the focus.
In VB, the control don´t disapear only in the Word.
Can anyone help me ?
thanks

Hi everybody
I have written an ATL 3.0 project including two sample classes named CAttachment & CAttachments. These classes have interfaces IAttachment & IAttachments in order. IAttachments has got a method named "Item" that returns a result of the type of IAttachment. But before returning the IAttachment, I want to call some member functions of the CAttachment class to setup the IAttachment properly. I know how to create the IAttachment interface, but I don't know how to have access to the members of the CAttachment from the "Item" method. I will be thankful if anybody replies to me.
Regards,
Roozbeh.

CAttachement *pAttach;
IAttachment pIAttach;
pAttach = (CAttachement*) pIAttach;
pAttach can now call the class members of the its class.
This space is empty.

|

*bzzt* Wrong way. This should never ever be done. You can never be certain what pIAttach points to. Any COM book will tell you this at least a dussin times. 
A better way to gain access to members of CAttachment is to use CComObject<CAttachement> instead.
CComObject<CAttachement>* pObj;
HRESULT hr = CComObject<CAttachement>::CreateInstance(&pObj);
pObj->AddRef();
pObj->member = value;
pObj->InterfaceMethod();
IAttachment* pAtt = pObj;

yeah correct.
Code Review Correction.
if(pObList == NULL)
{
pObList = NULL;
delete pObList;
}

Surely not.
if (pObList != NULL)
{
delete pObList;
pObList = NULL;
}
unless, of course, you've worked where I'm working at the moment, where apparently that would be an acceptable style of coding.

sure i aggree with you, it was the code review correction that i gave to my coworker (its a mistake that i asked him to correct it)
but for some reason, that piece code works perfectly, coz deleteing null pointer is ignored.

Indeed
However, unless somewhere there is a corresponding delete for non-null pointers, I suspect you might have at the very least some diagnostics about leaks when running under the debugger.

no this is was the only delete for that object in the dtor. Yes there was a memory leak in this case and other places.
I just placed it in my sig to show that how stupid anyone can get to write that kinda of code.
But then i removed it coz i thought it was not rite to make a joke of others programming pratice.

Hi, I've an ATL activeX control that is a dialog with some windows. When it's hosted in IE there are resizing problems (it has resizing border) when IE isn't maximized. The dialog will not draw outside its original size, even though the border seems to drag out to a much larger size (the controls and dialog size, but are clipped to the original width and height). This doesn't happen when IE is maximized, as the dialog and controls are drawn to new sizes/positions.
I've no idea of the cause, is it a bug in IE or just a special case I need to account for in the code?
Thanks in advance.
Brian.

in a BHO, if the user clicks on any word how can i know which word user clicked on
there is a function elementFromPoint but that will give the whole Element i want the specific text
how does IE know that the stuff under the mouse is Text cause the mouse pointer changes to a carat when the mouse moves over text on a HTML page
