Re: AfxBeginThread may use in activex control(ATL)?

Me too! I discovered that only this week and I now use _beginthreadex exclusively. If you use CRT (especially date/time) functions in a thread, then without _beginthread[ex] you will leak memory - OK, not a lot, but a leak is still a leak.

Multiple Event Sinking and Firing Event

Hi,
I'm having trouble firing an event. I have class derived from IDispEventImpl to advise for multiple object sources. This is fine, however, I'm trying to Fire_XXX() event from this class, but the method is declared in CProxy_IXXXEvents class. Any ideas how I can do this. Here is code snippet.

"..\COMServer.tlb" //receive events from other object

class ATL_NO_VTABLE CServer :
public CComObjectRootEx<ccomsinglethreadmodel>,
public CComCoClass<cserver, &clsid_server="">,
public IConnectionPointContainerImpl<cserver>,
public IDispatchImpl<iserver, &iid_iserver,
&libid_serverib="">,
public CProxy_IServerShellEvents< CServerShell >
{

};

//Sink Class
class CSinkServerEvents :
public IDispEventImpl<0, CSinkServerEvents, &DIID__ICOMServerEvents, &LIBID_COMSERVERLib, 1, 0>
{
BEGIN_SINK_MAP(CSinkServerOEvents)
SINK_ENTRY_EX(0, DIID__ICOMServerEvents, 0x01, Calculate)
END_SINK_MAP()

HRESULT __stdcall Calculate(short value)
{
Fire_OnXXX(value);
return S_OK;
}
};

//This Class I'm trying to access this class method from the EventSink Class.
template <class t="">
class CProxy_IServerShellEvents : public IConnectionPointImpl<t, &diid__iserverevents,="" ccomdynamicunkarray="">
{
public:
HRESULT Fire_OnXXX(short value)
{
...
}
};
Thanks

I have created simple login password atl com component and added to html or it gives that html. control has a button on clicking which it checks in database
if username and passowrd is valid it enters the relevant info in database
and also displays message box that login is successful or else. I want
that if login is successful it must go to next page. how it is possible?
Either my control must fire some event (window event) which I can catch in html but
It seems to very complicated task as I must have to have handle of html window and lot more. Simplest is html must check in database that login is successful or not ,if yes go to next page.Can any body let me know how to access database through html or redirect me to some reference.

To add WTL support to the WinAPI DLL project

I am trying to add WTL support to the WinAPI DLL project.

I was write in the stdafx.h:

#include <windows.h>
// C RunTime Header Files
#include <stdlib.h>
#include <malloc.h>
#include <memory.h>
#include <tchar.h>

#include <atlbase.h>
#include <atlapp.h>

extern CAppModule _Module;

#include <atlwin.h>
#include <atlgdi.h>
#include <atlmisc.h>

Compiler messages was:
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinSock2.h(1149) : warning C4005: 'BIGENDIAN' : macro redefinition
c:\MyProjects\TQPS\402Headers_Libs\Win\XTPLAT40.H(148) : see previous definition of 'BIGENDIAN'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\atlcore.h(246) : warning C4002: too many actual parameters for macro 'LoadResource'

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\PropIdl.h(915) : warning C4002: too many actual parameters for macro 'Create'

and so on... There was 75 errors. That is the problem? The same includes in a blank WinAPI project are working well.

Could anyone help me? Sleepy | :zzz:

Hello dandy_andy!

You have make like this:

CAppModule _Module;

BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
{
HRESULT hRes = ::CoInitialize(NULL);
ATLASSERT(SUCCEEDED(hRes));

hRes = _Module.Init(NULL, (HINSTANCE)hModule);
ATLASSERT(SUCCEEDED(hRes));
}
break;
case DLL_PROCESS_DETACH:
{
_Module.Term();
::CoUninitialize();
}
break;
}
return TRUE;

Hi,

I'm pretty new in programming in c++.net, and I was wondering if someone could help me out.

The goal is to control Abobe Acrobat so that it displays a pdf file in my own c++.NET application. I have found an example in the Acrobat SDK called ActiveView which is exactly what I want to achieve, but I have really no idea how it works.

Can anybody give me an explination of how it works, or how to make a start?

thanx!
Bas

31-May-06 18:36

Hi,

I developing a component using ATL. This component is suppose to generate events. The wizard generated the Proxy Class implementation of Events (CProxy_xxx).

I am trying to Fire an event using this class implementation.

But I am recieving 0x8002802B ( -2147319765 ) TYPE_E_ELEMENTNOTFOUND error.

I am passing two parameters which are of type IDispatch*

The client used is VBScript.

Does someone here has any idea about what possibly would have gone wrong?

Thanks for looking into this.

Maybe

SELECT * from FDetails where ddate = "05/29/2006"

or

SELECT * from FDetails where ddate = #05/29/2006#

I believe this is not a post for the ATL/WTL/STL group... Sniff | :^)

Hi,

I have an Window which has Edit Controls.

How do I change the font for an edit Control?

I am unable to trap the Backspace key for the Edit Control. When ever I press Backspace on the Edit Control, the backspace is caught by the parent window. Can anyone tell me why?

On setting the font: look up the WM_SETFONT message. You don't mention what libraries you're using but some libraries will have wrapper functions which send this message for you.

Hi.

Thanks for your reply. It is indeed the WM_SETFONT message. I am using WTL 7.0 so I could do it with SetFont().

One queston which I would like to ask is, How do I change the Height of an Edit Control? Well, I am using SetWindowPos, but the height is not being set accoring to what I give the SetWindowPos function. Does the Edit Control have any other means by which its height can be changed? Also you may be thinking that the height of the control will not be smaller than the height of the font. Let me assure you that I have changed the height of the font using the SetFont() method.

Any suggestions?

SetWindowPos should work just fine. e.g.

::SetWindowPos(hWnd, NULL, 0, 0, 100, 100, SWP_NOZORDER|SWP_NOMOVE);

Did you:
1. Pass the correct window handle. To check you can do something like call GetWindowText with the HWND and make sure its the correct control; or you could use Spy++.
2. Did you pass the correct flags to SetWindowPos?

Hey Stephen,

I am sure you aren't gonna believe this but I have been a #$%^#$ Ass Mad | :mad:

. I wasted one whole day trying to figure out why SetWindowPos is not working and I found the culprit. The culprit is ME. Sigh | :sigh:

Instead of passing the Height and Width to the SetWindowPos function I was actually passing the position for the right and bottom corners of the control relative to the Left and top positions.

It was something like, if the top of the control is 20 then to get a height of 20, I was passing Top+20 to the Height argument. How silly of me. Blush | :O

Anyways, thanks a lot for your support. I really appreciate it.

Thanks once again.
