The constructor is not public, so how can you create an object like that? Also, I don't see why would you receive a C4430 for this. I thought it must complain about not being able to access a protected function. (C2448 or whatever, I ain't sure - don't have a compiler here Searched for it, found it - C2248[^]).

Look at the placement of the reference specifier (the &). It' meant to come after the type you want to reference. So, the compiler is seeing const&base as (const&)==type and (base)==parameter name.
Solution - use const base&.

We have ported windows active x control plugin from 32bit to 64bit and we build cab file with my inf file.
We used dependency dlls mfc42.dll,olepro32.dll.
when we try to install cab file ...it crashes....
Do we need to change those mfc dll for 64bit?
Need help on this.
This is my detailed steps
1. Used VS2008 and compiled my active x control project with settings x64. IT generated my.ocx file and my.dll
file.
2. My inf file is
[version]
; version signature (same for both NT and Win95) do not remove
signature="$CHICAGO$"
AdvancedINF=2.0
[Add.Code]
my.ocx=my.ocx
my.dll=my.dll
; These are the necessary supporting DLLs for MFC 4.2 ActiveX Controls
mfc90.dll=mfc90.dll
msvcr90.dll=msvcr90.dll
olepro32.dll=olepro32.dll
rac5vml.dll=rac5vml.dll
; thiscab is a keyword which, in this case, means that rac5vm.ocx
; can be found in the same .cab file as this .inf file
; file-win32-x86 is an x86 platform specific identifier
; See the ActiveX SDK - ActiveX Controls - Internet Component Download -
; Packaging component code for automatic download
[my.ocx]
file-win32-x86=thiscab
; *** add your controls CLSID here ***
clsid={CCA1618B-7D6E-4432-8FA4-3E01A1AD78A8}
; Add your ocx's file version here.
FileVersion=0,0,0,0
RegisterServer=yes
[rac5vml.dll]
file=thiscab
FileVersion=0,0,0,0
[libeay32.dll]
file=thiscab
FileVersion=0,9,7,6
[libssl32.dll]
file=thiscab
FileVersion=0,9,7,6
I tried with mfc90.dll as well as still it crashes...Please help me out here.

I am using VC++ MFC Application wizard.I am having Windows 2000 professional at my work place.Actually there are many word documents with almost the same information, with little changes.As saving all these word documents will take unneccesary space in the system,I would like to use crystal reports,so that I can set the common format of this word document and make them as report and print whenever necessary.
As I havnt worked on crystal reports before, I just wanted to know Can I do the above procedure and which version of crystal reports should I download for Windows 2000 professional OS?Can anyone tell me..pls?

Hi,
Currently i write a program allow a user key in the numeric number into edit control. When the user press 'OK' button, it will check the contain what user key in, if is not a numeric number, it will popup a message box..
But i think this method is a bit not convenient, so is there any method can check the value when the moment the user is key in without press the "OK" button.
I'm waiting from your reply. Sorry for my poor English....

The parent window of the edit control will receive the EN_UPDATE[^] notification before the text is displayed. In this handler you can check the edit box text.

There is also property "Number" for edit control.
Check if it suits your need. I think it will not allow -ve and floating point numbers as well.
But it is better to check also as users can always copy paste anything they want in the edit box.

Sandip.

Same as the previous reply: if you only need a basic numerical edit (no floating point for instance), then you can simply set it as a property on the edit control. Only numbers can be entered then.
If you need something a bit more complex (e.g. support for floating points), you could reuse one of the existing control on CP[^]. The first one looks promising but you might want something simpler. Simply check the list and find something that suits your needs.

Thank you for the guide. i will try my best to done it. 
by the way, the data i store is include the floating number..

Hi,
i need to increase the height of a headerctrl ..So can i call Movewindow() in DrawItem method...
Please correct me if im wrong..
|
|
|
|

Are you trying to increase the height of a list control's header control? If it is, I guess the only way for doing that is by changing the font size of the list control.
|
|
|
|
|
in onpaint() of headerCtrl i changed the font but the issue is only half of the font is visible in Header ctrl..when the font is bigger...
|
|
|
|
|
No no..Change the font ( Call Setfont() ) of the list control from the onInitdialog() function of the dialog.

In Windows Vista (only) when I double click on a file in Windows Explorer that is associated with my application Vista displays: Windows cannot find "abc.def". Make sure you typed the name correctly and then try again." Where abc.def is the file I double click on in Explorer and it is associated with my app.
My app starts, if it isn't already running and the file does get opened correctly. Likewise if my app is already running the file is opened correctly. But this error is always displayed.
If instead I use "Open With" and select my app the file opens and no error is displayed.
I've Google'd and found various posts from people getting this error with Word, Excel files etc. but no real solution.

Neville - a suggestion - why not use Process Monitor[^] to see what Windows is actually looking at - you may well find the operation that can't find abc.def, and that might give you the clue you need to solve the problem?
That's what I'd do, anyway!

Thanks Stuart. I just tried PM and scanned several thousand log entries but nothing really stood out. MS has changed (broken) various aspects of File Associations with Vista and MFC in VS2008 has not been updated to address these issues. That said I don't think this is the cause of the error. It seems as though Windows Explorer is misreading what is going on.

Mostly to do with DDE from what I've read?

Yes DDE no longer works in Vista from Explorer, yet CDocManager::RegisterShellFileTypes() still registers as a DDE client. Further RegisterShellFileTypes() still uses HKEY_CLASSES_ROOT which can't be used on Vista. There is a Linker option "Per-User Config" and AfxSetPerUserRegistration() which I assume trigger RegOverridePredefKey() so HKCR morphs across to HKCU. And finally Vista has a new IApplicationAssociationRegistration::SetAppAsDefault Method which adds an app to the list of Default Applications and uses HKCR!!!
It only took me most of yesterday to get to the bottom of this. (:

Hopefully it won't change too much more for Windows 7...

Well I'll be testing that next. But one has to assume (pray/hope) it is the same as Vista.
I think I've finally found the cause which is a lurking HKCR shell\open\ddeexec = [open("%1")] entry. I thought I'd got rid of these, but this one reappeared. Maybe I'll end the week (Oz) on a good note after all.

Im looking for documents(programming languages) that would guide me in creating an interface that reads network data. So i guess i should start by creating the interface or finding out how to read network data and input database.
