Hello friends,
I want to use outlook express in my vc++ project to send email.
when i will try to send email then outlook send mail dialog box should open.
we only need to show outlook dialog box with attached file
to the user. after that it is up to the user to send email or not

Does it have something to do with ATL, WTL or STL ? If not, this is the wrong forum.
For your question, look for Outlook Automation (on google for example), it can be helpfull.

Knock out 'T' from CAN'T ,

Hi All
I am writing a component using ATL.
One of the method from the component accept a pointer to a structure. This structure definition is in other header file.
[id(3), helpstring("method get_StreamMediaType")] HRESULT get_StreamMediaType([in,out] AM_MEDIA_TYPE* pVal);
AM_MEDIA_TYPE present in 'strmif.h' file.
When I am trying to compile the project it gives me error in IDL file as
.\DSMediaInfoServices.idl(24) : error MIDL2025 : syntax error : expecting a type specification near "AM_MEDIA_TYPE"
.\DSMediaInfoServices.idl(24) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation
Thanks in Advance.

I think you need to add header file in the component so that idl can understand what is AM_MEDIA_TYPE

hello ,how can I ask question in here? I just can't find a place to post my
question .Which button allows me to write?
I have use WTL from a short time ago. I didn't know MFC very well.
so , about the macro of message ,they are so hard for me !
I wonder all the message function protype(and how many they are).
ok , MESSAGE_HANDLER ,COMMAND_HANDLER, and which like ON_BN_CLICK, MSG_WM_*,
NOTIFY_HANDER, and so on ,is they are different? Give me a detail describe.
Thank you!
I like my job.

it better you copy that structure in your IDL file!

There is also a strmif.idl file, which includes axcore.idl which defines that structure AM_MEDIA_TYPE, so I would import "strmif.idl";to get hold of the definiton

I want to create a DLL which will have to create windows and dialogs, and wanted to use WTL for creating the DLL. I know it's possible to create a DLL with MFC and so thought it might be possible to do it with WTL. Is this the case and if so does anyone have a demo project available ?
|

Thanks again hfry! On first look I found two relevant source files - wtldlldialog.zip AND WTL_DLL.ZIP. It's too late now to check them out, but I will look at them over the next couple of days...... I may be back in the near future asking more questions 
Let me give you some background to my problem.... I have a C-based app which has a plugin interface which supports certain features. When implementing these features, it is sometimes necessary to create windows and/or dialogs. I wanted to create it using WTL so that I can benefit from all of WTL's great classes for GUI implementation (including CDialogResize).
Anyway, that's the second time you've helped me, and I really appreciate it.
Best Regards.....

I have ATL 3.1 and WTL 7.0 installed. Are they compatible?
The reason for this is that Windows 2000 comes with ATL 3.1 and since I didn't get WTL 3.1 anywhere, I downloaded WTL 7.0. Everything was working fine, till I had to use the CPaneContainer class. To use this class I had to include atlctrlx.h to my project and that's where all the trouble started. Now it throws an error at compile time saying...
d:\program files\microsoft visual studio\vc98\include\atlctrlx.h(802) : error C2039: 'ShellExecute' : is not a member of '`global namespace''
Could anyone tell me why this error? Is it due to the version incompatibility? If yes then can anyone guide me to a download link to WTL 3.1 or ATL 7.0. Will ATL 7.0 work on Windows 2000?
Thanks...

Hi,
I got hold of the culprit. The error was occuring due to the WIN32_LEAN_AND_MEAN macro. When the macro was defined it removed the header where ShellExecute was declared.
Thanks....

Yes, you can use WTL 7 with VC 6 (WTL is AFAIK still being kept backward compatible with VC 6).
#include the right header to get the ShellExecute() definition.

I am creating a console application,in which I create an instance on IE and hook an event sink to it.The main code is as follows:
CoInitializeEx(NULL, COINIT_MULTITHREADED);
IWebBrowser2* disp;
HRESULT hr;
hr=CoCreateInstance(CLSID_InternetExplorer,NULL,CLSCTX_LOCAL_SERVER,IID_IWebBrowser2,(void**)&disp);
if(SUCCEEDED(hr))
{
disp->put_Visible(TRUE);
LPSTREAM pStream = NULL;
//marshalling the broser interface
hr = CoMarshalInterThreadInterfaceInStream(IID_IWebBrowser2, disp, &pStream);
.......
HANDLE hThread = CreateThread(NULL, 0, ThreadProc1,pStream, 0, &dwThreadID);
WaitWithMessageLoop(hThread);
......
}
}
...........
disp->Navigate2(&vurl, &ve, &ve, &ve, &ve); */
CoUninitialize();
In threadprocfunction,i create an instance of teh sick and hook it to IE
CoInitialize(NULL);
........
// get proxy to interface and release IStream
HRESULT hr = CoGetInterfaceAndReleaseStream(pStream, IID_IWebBrowser2, (LPVOID*)&psIE);
HRESULT hr=CoCreateInstance(CLSID_InternetExplorer,NULL,CLSCTX_LOCAL_SERVER,IID_IWebBrowser2,(void**)&psIE);
....... //Create the listener instance
hr = CoCreateInstance(CLSID_emplaybacksink,NULL,CLSCTX_INPROC_SERVER,IID_Iemplaybacksink,(void**)&tsink);
....... {
AtlAdvise( psIE,pUnk,DIID_DWebBrowserEvents2,&m_dwCookie);
........ }
The Atladvise action causes IE to hang during navigation.It proceeds only after the application has exitted.It seems there is a deadlock when IE calls back into the event sink.How can i avoid it?

1. You shouldn't call CoInitialize in the thread-proc (don't know if that affects you problem, though).
2. You CoCreateInstance Internet Explorer in your thread-proc, replacing the interface pointer passed (by marshalling) to the thread.
I think the main thing is that your thread doesn't have a message loop, so it's unlikely that connection points will work, as they rely (IIRC) on Windows messages.
Why use multiple threads, anyway? Connection points & IE work fine in a single-threaded app...

Yes, you should. Every thread that uses COM must initialise COM; these calls are also how you inform COM of your thread's threading model.
Stuart Dootson wrote: that connection points will work, as they rely (IIRC) on Windows messages.
No they don't. They are simply interface method calls, typically calls to IDispatch::Invoke. STA threads are required to have message pumps but MTAs do not need them. The only time when not having a message pump will affect calling a connection point is if the sink is in a STA and it is called from another apartment. This issue is not related to connection points; it's a general issue.

Actually i had initalized my new thread within an MTA too;but the results did not change .
When i try this with a GUI based application - firing the IE on the click of a button ;everything is fine - and the component receives the call-back on navigatecomplte/documentcomplte etc.
Is tehre any suggestion no how to make the console application implement a message handling framework as a ATL GUI based application?

Here's a complete example. It handles the new window and quit events from IE. It's a console app using no libraries (apart from the standard library) and uses two MTA threads like your code:

So did you solve your problem? If so how? The people that contributed are generally interested in knowing the outcome. This is a small price to pay for free technical support.

Sorry for the delay in reply steve.Still workign out how to trap the documentcomplete event - the problem is if we set the event to signalled state(setevent) from documentcomplete;the browser continues to hang -doing setevent in the quit event is not an option for me ,as the app would play all the html events without any manual intervention.
Just trying to figure out if its a behaviour of documentcomplete stage,or some mistake on my part.
Thanks a lot for the help - will keep posted about my findings
