I tried recompiling the third party library using the new iostream header files under VS2008, but it gives me compilation errors which seems to be some in-compatibility issues of new and old iostreams.
That sounds about right. I suspect you're going to have to bite the bullet & just start going through them, fixing them.
One thing to remember is that (IIRC) old iostreams weren't in the std namespace, new ones are. Also - this page has some handy migration hints[^].

Here is a sample code to reproduce the problem.
You were lucky before. MAPI and SQL both define BOOKMARK. They happened to both be 32-bit, but now they're not. The only things I can suggest are 1) separating SQL and MAPI functionality into separate source files, or 2) putting (say) the MAPI stuff into a namespace like this:
namespace MAPI
{
#include <mapix.h>
}
and either using using namespace MAPI; or explicitly identifying things in this new MAPI namespace.

Hai!
I have an MFC application in which if i press a button, a message box pops up. In that message box i have to display the Error message and caption so i am using MessageBox () instead of AfxMessageBox () since in AfxMessageBox () i cannot specify the caption.
Now the problem with MessageBox () is for as many times I press the button that many time the message box pops up, but if i use AfxMessage box it pops up once unless i respond to it i am not able to press the button in the main dialog.
So i need in this format i want to display the error message, its caption but unless user responds to that message box i must not be able to press the button as it happens in AfxMessageBox ().
I tried with the following, but still multiple messagebox pops up if i continously press the button in main dialog
MessageBox ("This error is due to XYZ", "Error", MB_ICONERROR | MB_APPLMODAL);
Thanks!

Is the solution secret? Other people may learn from it...
My guess is you didn't have the parent window of the ::MessageBox set - Just NULL isn't good enough.
Do I get a prize?

windows api function MessageBox yes, AfxMessageBox function MFC Yes
|
|
|
|
|
MessageBox ("This error is due to XYZ", "Error", MB_ICONERROR | MB_APPLMODAL); (YOURS)
MessageBox ("This error is due to XYZ", "Error", MB_ICONERROR | MB_SYSTEMMODAL); (MINES)
The only difference between applmodal and systemmodal is systemmodal is given TOPMOSTWINDOW also, therefore, you would have to manually give focus back to the main application before pressing XYZ, or whatever it is first

Hello,
I dont why my question was mixed up with other questions so posted again
I have a CRichEditCtrl box on a CMDIChildWnd. When I move the mouse over this edit box its cursor changes to caret pointer indicating that the box is there. This CMDIChildWnd is made by Create()of CMDIChildWNd
Now when I make a Child window by CreateNewChild() and the add CRichEditCTrl on the childwindow the edit box is seen but when I move the mouse cursor on the edit box the cursor doesnt change to caret pointer .
What is the difference or what must be the problem in making child
windows in diff ways?

Hello,
Once I got a debug error and from then I am not getting any info in Class Wizard. I did rebuild the project but when I press Ctrl W I am getting this error
Parsing error Expected "virtual"
Input Line "void KILLFOCUS(WPARAM wParam,LPARAM lParam)"
Thanks

At KILLFOCUS you created in the Class Wizard does not exist.or is not a virtual function.KILLFOCUS in front of you to add at virtual.

I need to write a PC based application that will utilize a bluetooth dongle using the Microsoft Bluetooth Stack. I was looking for any recommendations on SDKs (comercial or otherwise) that anyone would recommend. Or are the Bluetooth apis well documented enough on the MSDN that no 3rd party SDKs are needed?
Thanks in advance
|

What do you need the dongle to do?
As long as it appears in the Device Manager, then all it's capabilities are available. If it's a network device, then it should act like all the other network devices, if it's a sound device, then it should appear in the sound device list.
|
|
|
|

The dongle is because the PC won't necessarily have any integrated bluetooth. I just need to be able to connect to a external BT device whose BT address I will receive at run-time and then I need to perform some OBEX transfers in both directions.
I haven't done any windows network programming so this would be new to me.

Hello,
I'm writing an application that needs to interface with a Maxatec MT-200 receipt printer. This is done through posting bytes to the device. I have successfully changed character encodings and made text bold in the past, so my basic approach is sound.
I am working off the MT-200 technical manual, but I don't seem to be having much luck getting it working printing monochrome bitmap images (bitmap in the traditional sense, 1-bit per pixel).
ftp://ftp.maxatec-europe.com/Public/Maxatec/MT-200_Technical.pdf[^]
Look to page 59 and 60, defining and printing a downloaded bit image. It certainly has me confused.
[Name] Define downloaded bit image
[Format] ASCII GS ∗ x y d1 ... d (x x y x 8)
Hex 1D 2A x y d1 ... d (x x y x 8)
Decimal 29 42 x y d1 ... d (x x y x 8)
.................
The number of dots in the horizontal direction is x x 8, in the vertical
direction it is y x 8.
Surely the number of horizontal dots is the number specified by x. Does it simply mean x must be a multiple of 8? When I write the following bytes to the device:
1D 2A 10 10 66 66 66 66 66 66 66 66
in an effort to define a downloaded device image, the device becomes unresponsive - it doesn't print any additional ascii bytes I might send. It certainly doesn't respond to the print dowloaded image command:
1D 2F 30
What should I do? Can anyone make sense of this documentation? I myself cannot work it out, so I'd appreciate if someone else could weigh in,
Regards,
Sternocera

My suspicion is that the printer has an 8x8 dot head.
So, anything it prints will have to be in multiples of 8. But they then have a choice. Ask people to set the size, but trust them to set the size on multiples of 8? Or make the parameter be number of "heads", rather than number of dots.
So, you send:
9x3, which means 9 heads wide, and 3 heads deep, which means 72 dots by 24 dots.
I hope that gives you a lightbulb moment! I've had similar fun working with an LCD remote display device in the past.

Iain,
hmmm. I'll look into that, thanks. It certainly doesn't help matters when the documentation is written in "engrish", with no practical examples.

I've been trying to work out a design problem with one of my pet projects. Essentially, it works on the process of Streams. A program will write to a Stream; this is an abstract class which multiple classes inherit from. For example, a program will write to a Stream, and this could write to either a file or the system console
This all works rather well so far, but one of my additions has made things difficult. This is the daisy-chaining of Streams. A Stream can forward its data onto another Stream. The problem is that this is rather easy to take advantage of. Currently, there's nothing stopping a Stream from forwarding its data to itself, causing a recursive loop. I'm not using Windows in any way, so there's nothing to stop the loop from continuing until the stack overflows into the text segment, rewriting the kernel's code. Is there any way to stop this from happening?

One way is to only allow daisy-chaining in stream constructors. Then, by definition, you can't daisy chain a stream to itself.
I believe .NET and the Java class library have that restriction on stream daisy-chaining.

That sounds like it will work. As soon as I implement thread synchronisation, I'll do that. Just one more question though: how would I pass a WriteFormat call down to the chained Stream? I can't pass it in the normal way, because there's no parameter name. I have no va_arg definitions. I'm thinking of something like this:
LinkedStream->WriteFormat(fmt, *((uint *)&fmt + 1))
Would this have any side-effects (disregarding security)?

Why not? Is it a platform limitation?
If there's no other reason, then va_args could work.
Alternatively, you could use operator chaining as with Boost.Format[^]?
