Hi!
I developped a MMC snapin that display an ATL object in the result pane (the one to the right).
The ATL object is a Composite Control. The control is showing ok but there is no functionnality except the buttons. I would like to add a progress bar but it doesnt work.
If anyone knows how to add the progress bar and make it functionnal. Or even better, if anyone knows how to use a CDialog (or anything CWnd based) based class behind that ATL object in the result pane. Help would be very appreciated!
Thanks

My goal: to be able to stop (and start, and stop again, etc...) left- and right-click events from going to Internet Explorer, AND to be able to send left- and right-click events to IE.
My situation: I've already made a toolbar for IE, and am trying to implement the above in this toolbar.
My efforts: I found the FreezeEvents method of IOleControl; would that work for part of what I want to do? If so, how do I implement it? I've gone crazy trying to figure out how to call the FreezeEvents function!
Also remember, I still need to know how to send those mouse click events to IE.
Help would be much appreciated!

Attache to the events of IE. You will get BeforeNavigate and such. then to simulate them youjust call Navigate2, Refresh, or Stop on the IWebBrowser2 interface. Also they have get_busy to tell if it is currently navigating/refreshing.
Cheers,

Uhhh, those things wouldn't help me a bit, I'm afraid  Re-read my message, and you'll see what I mean. Basically, I just need to disable all right- and left-mouse button clicks, within the web site pane of Internet Explorer (disabling it within all of IE would work, too).
Please help! I'll be able to make a killer helper for IE, if I can just get that figured out  .

NM, I figured out how to do it! I just created a MouseProc hook, and returned -1.

I writed dll via MFCAppWizard(dll) [extention dll] in vc++
and it's works excellent by client program in mfc. 
----------------------------------------------------------
Now I need provide the dll for Delphi
So * I created ATL by ATL COM AppWizard (with support mfc)
* I added to it a ATL class (by the wizard , of course)
* I imported function from my mfc DLL as I did at the client program in mfc.
-----------------------------------------------------------
But It is not works !!!!
When I execute this ATL object by client program it does not perform the imported funcyion in run time.
----------------------------------------------------------
Who can help me ??????

Did u use AFX_MANAGE_STATE() ?
And also u should not try to use the
classes from the MFC dll in the ATL program,
u can only use the functions.
If this does not help, further information
can help me anlayse it.

I must provide dll that will match to every language !!!
I did exctention dll that works well in vc but NOT in another.
I understood that the best way for me (as beginner at this subject) is to use the Wizard of ATL COM with suppot MFC and importe my mfc dll to it.
When I run it by client program (exe) the atl it works !
but the imported function (ShowDialog) dont performed. WHY ????????
------------------------------------------------------------
My steps:
1. I opened project: ATL COM Wizard. [DLL] [MFC Support]
2. I inserted to the library that created the file : MyMfcDll.dll
and attached to the ATL project the files : MyMfcDll.h , MyMfcDll.lib
3. I Added by wizard ATL class [MyClass] [single] [dual]
4. I added by wizard method [ShowMfcDialog] to IMyClass and fill it so :
___________________________________________
extern "C" __declspec(dllimport) void ShowDialog();
STDMETHODIMP CAtlObj::ShowMfcDialog()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
AfxMessageBox(".....");
ShowDialog();
return S_OK;
}
|
|

|

I trys now to build ATL without import the MFC DLL that I crated.
So
1. I going to resources and inserting Dialog.
2. I created class dialog::CDialog (possibility ?)
3. I added ATL class - simple.
4. I added to this ATL class object from the class dialog .
5. I added to this ATL class method that doind : dlg.DoModal();
I run it from client program and it is works so :
It shows the dialog of the method of ATL class (in number 5)
But when press OK or Cancel it is crush.
____________________________________________________-
Have I use only in ATL dialog or there are a way to works as I tried (Maybe have I added AFX_MANAGE_STATE somewhere)?
What I need to add in the: () of that ?

We're making an ATL object to be used in ASP or Visual Basic.
I want to be able to return a BSTR to make it nice and pretty for my VB partner.
Ok ok, we all know that you can say...
///////////////
STDMETHODIMP Foo([out,retval] BSTR outstring)
///////////////
..and have it returned in a variable in the Implementation. (duh)
But can we get this a function in an object to look like:
///////////////
BSTR Foo(BSTR instring);
///////////////
or just something with the emphasis on returning a BSTR in the "real" return parameter place.
"The Master Wang" doesnt have money to buy a COM or ATL book...
and plus I know I'm asking questions from the best!
SHABBA!!

If I understand what your asking
STDMETHODIMP Foo([out,retval] BSTR return_string, [out]BSTR out_string)
would get you
BSTR Foo(BSTR instring)
BTW, nice sucking up;)

Hi,
Actually you can use any data type "Automation Data Types are recomended" to be a return type of any interface's method. But, it's just a recommendation that you use the HRESULT (STDMETHOD macro) as a return type, this return type will give the COM Runtime Environment the ability to return error codes when your component cannot be accessed for any reason. If you don't provide HRESULT as a return type, the COM Runtime Environment cannot return error codes for you.
"If You Know That Your Component Will Live With Its Client On The Same Machine, You Can Ignore HRESULT"

ShadiK.

No, COM interfaces can't return a value like you suggest.
The correct (and only way) is as you described,
STDMETHODIMP Foo([out,retval] BSTR* outstring)
Your VB code would then look like,
Dim sTemp
sTemp = Object.Foo
Hope this helps,
Michael

The solution is simple. In your source file (.cpp) change your function header to this:
STDMETHODIMP_(BSTR) YourClass::Foo(BSTR instring)
and do the same for your (.h) file.
You need to change the entry in the IDL file as well,like the following:
BSTR Foo(BSTR instring);

STDMETHODIMP Foo([in]BSTR in_string, [out,retval] BSTR *return_string )
would get you
String Foo(String instring) in VB or ASP,
In C++ it is HRESULT = YADA.Invoke(dispID, params, vResult,...)
Your out_string ends up in the Variant vResult as type vt = VT_BSTR. Use of the retval modifier causes the result to be placed in vResult. Notice the * in BSTR *return_string.
Hope this helps,
Bill

Howdy.
I have a large, multiserver project that has been developed in VC++ on WinNT 4.0 SP6a. It makes use of ATL for most of the COM-related things.
My trouble is that it works fine on the machine on which it was developed. I have tried it on other machines and sometimes it works fine - sometimes it doesn't.
The current issue is that when I regsvr32 my servers, I get the standard message that says that registration was successful. Trouble is, nothing shows up in the registry!
Do ATL-based servers require some fancy libraries for registration? Do they require any libraries that get loaded with MSDEV or a certain service pack? I'm trying to make do without loading the development environment on the machine (it will be a production machine eventually).
Any help would be GREATLY appreciated.

Follow-up...
The problem persists. I searched the MSDN library and found a reference to some run-time issues. They suggest you do a release min dependency build and remove the _ATL_MIN_CRT define.
I did it, registered the server, it said that it worked, but didn't touch the registry.
I'll add that I'm working as an administrator, so registry security should not be an issue. Also, my .exe servers added their CLSIDs and APPIDs, but little else. So something's working - just not enough to actually be useful.
Puh-leeeeeze hep me! Hep me!

Sometimes, a proxy/stub Dll needs to be registered. Does your application make use of an external proxy/stub dll?

It does, and the same problem occurs. I believe the PS dll loads stuff under the AppID key under HKCR? Either way, when I regsvr32 either one of them, they both "succeed" but neither actually touches the registry.

Oops. The PS does NOT put entries in AppID. My mistake.
The problem remains.

Try to move the ATL.DLL with you.

Hello...I already posted this in the "Visual C++" area, but I've gotten no response, so I'm trying it here, since it's technically a COM issue. 
I'm working on a namespace extension for Windows NT that represents documents in a repository. It allows the user to copy or cut the documents and paste them to the file system. I'm basically doing the cut/copy by retrieving the files, copying them to /temp, and creating an IDataObject instance on the clipboard which returns a reference to the temporary files in CF_HDROP format.
BUT...in the case of a cut and paste, I need to get feedback that the paste was successful so I know whether or not to delete the document object from the repository. I get a "Paste Successful" via IDataObject::SetData(), but if the file already exists where I'm pasting it, I get a "File already exists - overwrite?" dialog box *AFTER* the "Paste Successful" has already been returned!
Is there a way to verify that the paste has actually occured?
Alternatively, is there a way I can add a handler of some sort to the shell that will allow me to paste documents to the file system that are in a custom clipboard format?
Any help would be greatly appreciated.
Thanks,
Tim

Hello,
I want to write a program that show some Powerpoint slides through LAN.
Could Office Developer help me anything?
please help me!
Thanks,

I am not a Office developer, but you have several options, for example, Powerpoint have a little quik view for it, in that case you only need to destribuit that application. If you are a Vsual c++ developer you can use Ole Automation....

Hi all,
I want to display my own HTML pages instead of IE res: error pages(dnserror.html etc). I know that the AboutURLs reg entries handle some of these but not the DNSerror. Now in my mind there are 2 ways to do this: either write a BHO IEplugin and trap IE events esp. BeforeNavigate2 and if res:// protocol pages comeup I just call Navigate() to go to my pages. the other idea is to replace shdocvw.dll and shdoclc.dll resources(I'm not sure of the merits/demerits of this). But then XXXUpdateResource() API's work only for WinNT and I want Win9x compatibility too. What should I do?
TIA.
