Hi,
Does anyone know if have to create a copy of IRichEditole
before SendMessage EM_GETOLEINTERFACE
Thankx
|
|

Please provide some more info what you mean. If i go by my guess about what you mean, then no, you just need an IRichEdit pointer which will be set to the instance of the interface when EM_GETOLEINTERFACE returns, as the documentation[^] says.

Hi,
I do the SendMessage EM_GETOLEINTERFACE
in my ::OnInitDialog right after I instantiate
my CRichEditctrl via new
I saw an example on the Codeproject by
Mike O'Niell
for IRichEditOleCallback he instantiates a copy
e.g.
Interface IExRichEditOleCallBack : public IRichEditOleCallback
{
}
on the heap before setting the address inthe SetOLECallBack
was wondering if the same was true for IRichEditOle
Thankx

I see. Well, in case of the IRichEditOleCallback, as the documentation[^] states, you are responsible to provide an implementation of the interface methods, this is probably why the exsample creates IExRichEditOleCallBack (from IRichEditOleCallback) and feeds that to the rich edit control. He provides implementations of methods that will be called "by the rich edit" (or somesuch) allowing him to execute his specialized code when something needs to be done.
When you query for the IRichEditOle interface, its methods are already implemented, you don't need to make your own instance of it since what you want to do is to use the already impelemented functionality.
I hope this is understandable rather than making things seem to be even more complicated than before.

This thread on nehe[^] is a good start.
It's not a very easy things to do, especially if you want to make it realistic, but the basics should manageable.
Watched code never compiles.

There are a number of different options; try searching the MSDN site for possible solutions that match your requirements. Your starter for 10: Remote Desktop Connection[^].

Hi,
I'm using CFileDialog to display a list of files to open, but when I change the extension type I don't get a displayed list of the newly associated files.
CFileDialog fileOpen(TRUE, "dat", "*.dat", OFN_EXPLORER | OFN_FILEMUSTEXIST, "Data Files (*.dat)|.dat|Doc Files (*.doc)|.doc|All Files (*.*)|.*||");
if(IDOK == fileOpen.DoModal())
{
....
}
It really is as simple as that, but the explorer doesnt seem to want to display the files associated with the new extensions.
Any ideas?
TIA
Tony
BTW - I'm using Visual Studio 2003 on an XP machine

I have multiple excel.exe running on my system . When I called GetActiveObject() method then I am able to get only the one excel.exe not all . So please tell me how can I get all the running excel.exe
Trioum

from what Ive seen GetActiveObject() is only going to get one instance. If you are looking for a particular instance, you could try looping :-
GetActiveObject()
Is This instance what Im looking for ?
If No CLose the excel instance
repeat until you find the excel instance you want
I was thinking that you could enumerate windows with Excel in the title, somehow close the ones you dont want (assuming you can detect the one you do want by the window title), then do a GetActiveObject()
sorry .. maybe someone else has a better idea
|
|
|
|

No your idea is failed every time I got the same Excel. And I cannot close the running excel.exe
Trioum

|

btw how did you implement either of my ideas ? and
trioum wrote: And I cannot close the running excel.exe
why not ? obviously if you cant close any excel instance you dont want then you'll never get to the one you do want.. what do you have so many zombie excel instances ?

I have to work with mulitple excel files not one dude

do you know if GetActiveObject() returns a reference to the Excel instance that 'has focus' or 'is currently active' ?
If that were the case, AND you could distinguish which excel instance was which by the Window title, then you could build a workable solution
a) enumerate all the excel instances and look at their window titles
b) force the instance you want (by window title) to come to the front ie give it focus
c) then do a GetActive Object
somehow I dont think its that easy - the GetActiveObject may have its own way of looking at the ROT or process table, not just the 'active excel instance' - thats confirmed by looking further : MS KB 238975 - http://support.microsoft.com/kb/238975[^]
says "NOTE: If there are multiple instances of an automation server running at the same time, the GetActiveObject() API function returns the IDispatch pointer to the instance that was first running."
So I dont think you're going to be able to do it
