I'm trying to generate .eml files with CDO 2000. But I got problems if the attachment's file name contains multi-lauguage characters. Then the attachment name will become ???????.
I tried two ways:
1. Set the file name directly with raw text.
2. Encoding the header (content-disposition) with RCF1522.
But I still got the same result.
Actually, I can call GetFileName() to retrieve the filename before writing stream to file, and it was fine. But something wrong happened when it generates the file.
Thanks a lot.

Dear all,
I m new to COM world, having basic knowledge about it.
I have to redesign a simple DLL project to COM DLL Server so that it can incorporate with existing application with least changes.
What kind of approach i have to follow in order to complete this task ...
Waiting for your suggestion ...
Thanks..

Basically you want to write a COM wrapper around a Simple win32 Dll isnt it?
Does this Simple win32 dll contains exported Classes? or simple C functions?
Cheers,
Suresh

Thanks for your kind reply ...
Yes a COM wrapper around a Simple win32 Dll. This win32 dll contains exported simple functions ...
Is this a fine approach or should i have start a project from start having all those functions of exported Classes in COM Server Dll.
Thanks...

Yeah, the approach is fine, but remember to distribute both the DLL's when you are publishing your application.

Can anyone please help me or give me some sample code? I need to create an ATL COM service (not a DLL) which has a dummy interface.. say. add 2 numbers.. After creating the service, i want to register it as a windows service. Then i want to create a client which connects to this service and uses the interface.. (adds 2 numbers)
I have searched online and there is not a decent article which explains the process step by step... Any help in this regard will be very useful.
Thanks in advance!!!!

Hai all,
-> I have a "COM Server Exe" , with connection point.
->And I made my COM Object class Singleton by using
Macro "DECLARE_CLASSFACTORY_SINGLETON"
-> My Com Cleint is a Dialog Based Programme .I started 5 clients by
clicking on same exe.
-> Whenever the client starts , It will set up all the connection points
-> I am able to call a COM Method( for eg: my_ComFun() ) by clicking a
button on my dialog box
-> From inside my_ComFun() I am firing an event to my client .
implementation of my_ComFun()
/**************************************************************/
STDMETHODIMP CMyServer::my_ComFun(int i)
{
Fire_MyEvent(i);
return S_OK;
}
/**************************************************************/
->Whenever I am Firing events from my COM Server(Using function
Fire_MyEvent() ) , All my clients are
getting function calls , since my COM Server is a Singleton class.
* My Requirement is to prevent this broadcasting and direct the function
calls from COM to that specific client which calls the Servers my_ComFun(),
by keeping the COM Server Singleton.
Thanks in Advance.

Hello,
I've written an ActiveX for IE in VS2005 C# .Net 2.0.
It supports RfID and GPS via COM-Port.
On my machine it runs great.
Now I wrote a setup with VS 2005.
I think I'm to set "vsdrpCOMSelfReg" for registering.
But it doesn't work.
It accepts only "vsdrpCOM"
After installation I called it in IE. It dosn't work.
When IE is open and I want to uninstall it by setup - Setup say "no, is in use."
I think, I'm not so far from target?!?
Can anyone help me?
I didn't find an good artikel in the internet.
Thanks a lot.
Additional:
In my IE I see the ActiveX in AddOns, but as File is listed "mscoree.dll"
What's that?
"Herausgeber" / Publisher is emty.
Maybe, it helps you.
Thanks a lot.

Register it! 
Run RegSvr32.exe from a command prompt and give the complete path to the server as command line argument. You'll probably find RegSvr32 in your system directory.
If the server is something you've bought, it should be registered by the installer if such exist.

Since it seems like you didn't get any compiler errors, the CLSID for the server is defined somewhere in your project. Look it up.
Open the registry editor and try to find the CLSID below HKCR\CLSID.
If you're not able to find it there, the server is in fact not registered and you should probably reinstall the SDK again. If that doesn't help I don't know what to do besides contacting the support for the SDK, unless you know what files to register.
If you are able to find it, does it have an InProcServer32 key below it?
If it does, what does the default value of it contain? It should contain the path to the server and if it does so, can you find the server where it says?

At some point you are dereferencing the NULL pointer.
Since your application uses COM I suggest you make sure that every interface pointer you use doesn't equal NULL.
Use the TRACE macro and print some debug info when you validate an interface pointer and it turns out to be NULL unexpectedly.

Hi,
Can any one expplain How to convert a CString to _bstr_t......
thanks in advance
Thanks a lot
|
|
|
|
|
One of the constructors of _bstr_t takes a const char* as argument. Since CString has a type conversion operator LPCTSTR that returns a const char* you can do the following:
CString str = "The string";
_bstr_t bstrTest( str );
bstrTest = _bstr_t( str );

No it doesn't. It returns const TCHAR*, which in a UNICODE build won't be the same as const char*. However, _bstr_t has a constructor that accepts const wchar_t* as well as one for const char*, so it will work in either case.
