i am trying to add the following function as public in my wNode class. my intention is to have a function that returns a two dimensional character array (basically an array of strings and ids)...this is the way i do it:
char[][] getContentArray();
it is giving me a compiler error -> error C3409: empty attribute block is not allowed
what's wrong?

You'll likely need to use:
char* getContentArray(); or
char** getContentArray();

still doesnt work..
this is what i have: (i have changed the header file appropriately)
char** workflow::getContentArray()
{
char content[5][5];
return content;
}
error C2440: 'return' : cannot convert from 'char [5][5]' to 'char **' -> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Why would you want to do this? content is no longer valid once getContentArray() goes out of scope. Try:
char* workflow::getContentArray()
{
char content = new char[5][5];
return content;
}

I am getting this error when I build my project.
error LNK2019: unresolved external symbol __imp__wprintf
I know that means I am linking to the wrong library. I think this is in the runtime library. I've tried the various settings (Multithreaded debug, Multithreaded debug dll) as well as all the other options. Some, of course cause many more errors, none make this one go away.
Please help. Thanks in advance for any advice.
Regards, Bill

Hi Bill,
I guess, you have "Ignore All Default libraries" option selected. Unselect this option. Go to project settings and choose Link option and uncheck the Ignore All default libraries check box (if you are using VS2003 and above, choose No in the list. The name of the item is same).
Hope that helps.
Kiran.

Hi Kiran,
Thanks for the reply.
Unfortunately, the developer on this project had already tried that setting:
Ignore All Default Libraries = No.
He also tried changing the Ignore Specific Library setting. He tried setting the ignore list to: LIBCMT;MSVCRTD;LIBC;msvcrt and received a large volume of errors. Also clearing the list resulted in errors. He finally reverted to the original list: MSVCRTD
If you have any more thoughts, I would appreciate hearing from you again. We are starting to fall behind on the project over this issue.
Thanks, Bill
Regards, Bill

hi all..
i want to write a class for which a private data member is an instance of that same class..
for example:
class wNode {
private:
wNode next;
wNode previous;
...
}
this should be a very standard thing to do - i can do it in java just fine. in c++, it gives me compiler error c2460.
how do i go around this or fix this to accomplish my goal??
thanks!

Define a pointer to the class, not an actual instance. That's what Java does even if the notation may confuse you to think otherwise.
class wNode {
private:
wNode* next;
wNode* previous;
...
}

Where are they?
I don't see them in VS2005's VC/PlatformSDK/gdiplusgraphics.h or elsewhere.
The DrawImage() version documented in their page isn't there either...

DrawImage(Image *image, RectF *sourceRect, Matrix *xForm, Effect *effect, ImageAttributes *imageAttributes,Unit *srcUnit);

The Authenticated User is in effect the user who is logged on in term of the pasrticular software of connection in use. In other words when you log on to Windows you are the authenticated user for Windows. This user can do whatevers their permissions and group membership allow then to do dubject to the policies det up by the Administrator,
Nothing is exactly what it seems but everything with seems can be unpicked.

Please help me do a query based on date.
I have m_pSet (a pointer to CRecordset) and a filter m_strFilter
my date is a ColeDateTime in the form of "mm/dd/yyyy"
I need to set: m-pSet->m_strFilter to select records with birthday=1/1/1970
Any ideas.
Paulo

What does your filter string look like?
What does the code look like that constructs it?
Also what does the code look like that executes the query?

Hello again board, thanks for answering my previous question. I never programmed for linux. I have about 10 programs(all of them have some sort of data acquisition) developed using MFC for win 98 and XP.recently I've been asked to provide linux versions of these softwares. Is it possible to convert them(each program is relatively big with ~20-30 classes)?

Since MFC are, by design, a thin wrapper around Win32, they are strictly tied to Windows hence you have to do a lot of work (of course it depends on how much is windowed is your application).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You might want to look into the Wine project. It tries to implement large tracts of the Win32 API on Linux so you can more easily port Windows software. I'm not sure if Wine is up to running MFC but it probably does to some degree.

Think about .Net framework.

|
Manish, Can you explain more, please. Do you mean .Net had less portability problems? How? Does it mean .Net is a universal language(probably portability to Mac)?
|
|
|
|

.NET is a framework by microsoft for Windows. the projects (like Mono) which extend the work of .NET to other systems than MS are individual works and not really official.
|
|

Hey, .Net is good alternative, as most of the .Net framework has been ported to Linux.
The Mono project provides the necessary software to develop and run .NET client and server applications on different platforms. Mono can run binaries produced by Visual Studio, there is no need to recompile.

if the project is targetted for different plateforms, you should consider using Multi-Plateforms graphical libraries like WxWidgets for instance (but many more exist though)
