Oh - thats new, then. The hole is closed here for years, now.
In XP you still could access anything not hidden well enough.
E.G. Your bosses USB-Stick (FAT-Formated as it is).

OK, again slowly:
Until recently, even in XP (I think), you could scan all mounted drives on all computers in the local windows-network (that is anything up until the next network router).
Anything between you and full access was the Windows file security. Non-existant e.g. on USB-Sticks.
That IS a security hole. Regardless what Microsoft-cultists say.
This could have been switched off in the registry. See here[^].
Our network policy enforces this.
Now you tell me, that this no longer the case. Fine.
It should have been never. And the ones responsible for that need to be disgraced until their fourth decendant.

As an owner of a small local area network with only 3 PC's in it all on my desktop I am glad this feature exists it makes it so much easier.

Easier than just creating a real share where you need it?

well actually no, because I know how to use Net Share from the commandline, but yes if all I had was the poxy windows folder share prpoerty sheet it is much easier because the property sheet sharing page wants to reset all permissions on every thing below the share point which is totally unneccessary in a desktop lan environment.

Hello,
I have a tab control, contents of which are displayed by a CDialog. This dialog contains different controls on it. I am having following issues :-
1) After I run my app, if I put another window on top of it (say calc.exe) and switch back to my app, I see the area convered by calc.exe is erased!
2) I have a menu which pops up if I do a right control on the header of my Clistctrl .. after the menu goes away, the area covered by the menu is erased and comes back only when I move my mouse over the area...
3) If I hit enter the contents on the tab control (which are displayed by CDialog) go away completely!
Thank you in advance for your help...

I guess it is because of z-order problem. What is the parent child relation of tab and the dialog having the controls?

Override OnOK() and OnCancel() in the dialog having the controls. Like OnOK() { } and OnCancel() { } in the class declaration. Rebuild the project to avoid compilation issues.

Thanks NS...
>> I guess it is because of z-order problem. What is the parent child relation of tab and the dialog having the controls?
How do I find that out?
Also, another problem I forgot to mention was .. if I hold on move my app window, the controls start disappearing ...
|
|
|
|

See, if a button is placed in a dialog, then the dialog becomes the parent of the button and the button is a child of the dialog.
Similarly, if the tab and the controls' dialog are the childs of the same parent, then there can be painting issues like you specified.

Why class CIOMessageMap should be declared by declspec(novtable)?
The macros implements the member function of CIOMessageMap --ProcessIOMessage();But in other places of project,there no any inheritances of CIOMessageMap.
Who can tell me the advantages about this coding style?
There are will best in detail.;)

ProcessIOMessage() is defined as virtual, so the compiler wants to add a vtable for the class. But, because it's an abstract class (due to the = 0) it cannot be instantiated and doesn't need the overhead of the vtable. __declspec(novtable) instructs the compiler to not generate a vtable.
A more detailed explanation can be found here[^].

Hi all,
I was able to set particular cell's content by CRange::put_Item() from MFC typelib class, but how can I set cell's background color and put comment into it? I've googled it but got no result so far.
Thanks,
|
|
|
|
|
To set the background color, look for an Interior property of the Range object, Interior has a Color property that specifies the color of the background, the Range can span cells.
To add a comment, use the AddComment method of the Range object.
|
|
|
|
|
Thanks, Roger!
But how can I reference the color property?
range.get_Interior();
and when "range.AddComment(COleVariant("1234"));" was reached an exception happened.
|
|
|
|
|
I am not using the same environment as you I am looking at the VBA for Excel and porting it into VC++6 wherein I get the Interior property which is an IDispatch and which has a Color property which I can set
Same with AddComment all I did was look in the MSDN documentation for the VBA Model of Excel and it told me Range had an AddComment method I have never actually used it, and even if I had it would be in VC++6 which doesnt use a CRange class.

Inside <<inside c++="" object="" models="">>, it wrote
"It is stll a bad design choice to declare all functions virutal and to depend on the compiler to optimize away unnecessary virtual invocations."
I can't understand it very well.
class Abstract_base {
public:
virtual ~Abstract_base()=0;
virtual void interface1() const = 0;
virtual const char*
mumble() const {return _mumble;)
protected:
char *_mumble;
};
As the source above.
"virtual const char* mumble() const {return _mumble;)"
If you define a member function to be virtual, you insert a vptr in your class object.
but as the function's defination has been claimed within the head file, it must be looked as an linline function. Is it right?
Tomorrow is another day!

I think what the author meant was that the compiler does not generate a vtable entry that is never needed. If you declare a function as virtual in a base class, and that function is always called in the scope of a known class, the compiler might as well skip the vtable entry for that function. Or if you declare a virtual fuction in a class with no sub- or superclasses, there's no point in using a vtable at all.
As for the inline declaration of a function, it only tells the compiler that you would prefer to have the code generated inline. If the function is virtual, you will still get a pointer in the vtable to that function (unless optimized away by the compiler).
Might add that I'm not an expert on the inner logic of an actual compiler, so the case may be a bit more complicated than this

Hello,
I have read an excel sheet using IDispatch.But I cannot read a particular sheet with a particular name.Also how to find the number of sheets in an excel file.
If I use CRecordset to open an excel file then how do I find the sheet name from excel file or I will I have to provide the sheet name like we provide a table name for the CRecordset object.
Any Ideas

So you have an IDispatch of a worksheet. Call GetApplication on the worksheet it will return an IDispatch of the Application. Call GetWorksheets on the application it will return an IDispatch of the worksheets collection. Call GetCount on the worksheets collection.
Or in VBA terms. A Worksheet has an Application property. An Application has a Worksheets property. The Sheets collection has a Count property. Sheets also has an Item property that takes a parameter of either the index or name of a sheet.

Hello,
Can I get the name of the sheet from any method of a Worksheet ?
Can I use CRecordset to open a sheet from excel file whose name(sheet's name) is not known.
Thanks for your help.

The most recent MSDN I have is Jan2002
wherein you drill down as follows
Office Solutions development
Microsoft Office
Microsoft Office Xp
VBA Language Reference
Microsoft Excel Visual Basic Reference
Objects
W
Worksheet Object
Name Property
no I dont think you can CRecordset a sheet whose name is not known (but I could be wrong)

I'm having a windows forms application project. On the form there's a datagridview with data of a table out of the datasources. The connectionstring in the datasource is made by the add new datasource wizard and is : Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\test\Tabel-XML.mdb
Changing it in the _Tabel_XMLDataset.h file doesn't do anything and changes after a new build.
Now I'd like to know if it's possible to change my data source, so make it variable. I saw something about the use of app.config but how do i have to do this then so that the data source of my datagridview is changed without rebuilding my project it each time after creating a new databaseconnection. I'd like to define the databaseconnection in an external file (like app.config) and then use this databaseconnection for my project. How is this done?
Thanks for helping me out
