You can write shell extension for adding additional items to context menu. For details you can refer The Complete Idiot's Guide to Writing Shell Extensions - Part I[^]

It's not as simple as that. There's not a WM_REFRESH type of message that you can send to a window and have it refresh itself. Using Spy++, you can see what messages are sent to the desktop's list control and how it responds. In order to mimic this, I suspect a shell extension would be in order.

Data is already in binary form, you know. What kind of conversion do you really need? Could you make an example?

ADODB::_RecordsetPtr rSet;

to get values from MS Access through this code.When Ms Access datatype is adLongVarBinary.

(j is indext number)
_variant_t vtValue;
vtValue =rSet->Fields->GetItem(j)->Value;

Then i am geting values like this

vtValue laues like this.
safearray = safearray of UI1 = [27609](21 ' ',28 ' ',45 '-',0,2 ' ',0,0,0,10 '
',0,15 ' ',0,20 ' ',0,30 ' ',0,255 'ÿ',255 'ÿ',255 'ÿ',255 'ÿ',87 'W',111 'o',114 'r',107 'k',115 's',104 'h',101 'e',101 'e',116 't',0,69 'E',120 'x',99 'c',101 'e',108 'l',46 '.',83 'S',10...

So how can i get this values in redable formate.

What do you intend with 'readable format'? What's the array is supposed to contain?

I think you are trying to get values from a SAFEARRAY[^]

I suggest you to read this (How To Pass Arrays Between Visual Basic and C[^]) article, to get a starting point in SAFEARRAY handling.

I think you can declare the global variables as static so that the access is restricted to specific translation units.

CPallini4-Jan-10 20:36

You should use the static storage class: from MSDN [^]

When modifying a variable or function at file scope, the static keyword specifies that the variable or function has internal linkage (its name is not visible from outside the file in which it is declared).

As people have already correctly answered you, using a static specification does this just fine.

If you are interested ( for culture maybe? ) there is another approach you may encounter. That is to put the variable definition in an anonymous namespace ( also known as an unnamed namespace[^] ).

Using VS2008, I've created an MFC TypeLib class, CApplication from _Application Interface in Ms Word 12.0 Object Library <8.4>. As expected, the class works with my Word 2007, but doesn't with Excel, PowerPoint etc.

My question, is there a way for me to create a CApplication class that caters to all the Ms Office family? I'm not looking at automating application specific functions, only common function (e.g: Save, Exit)

You cannot do it.

It's a COM interface and all applications have a different signture and functions.
So you need one per application and per version.

Too bad. I was hoping for an _Application interface that's being shared among all Office Apps (eg:_CommandBars). Does this mean I have to create individual dll for each Office App? I saw a few com addin that's available on my Word, Excel and PowerPoint. I don't think they have 3 separate dlls. Any idea how they are doing it?
