Thank you, I included float and it works much better.

maybe you should try acquiring each number one at a time within your void function. Also, what are you including?

I really appreciate the tip. I put using std because I don't know when not to use it , so I just put it in.

I'm writing an activex, and I need a method that return 3 values, (a string and 2 longs).
I will use the activex in Visual Basic.

What kind of return should I use?.

Could I return an object?.

if I can, how I do that?.

Any other idea??

Thank you.

Using fprintf in sockets

Hello. I once saw a piece of code, which used fprintf instead of send(), to send data via winsock. How can I "convert" my socket-handle into a file-handle, usable in the fprintf-function ?

Thank you.

Does anybody know of any utilities that can be used to convert from Borland C++ Builder 1.0-3.0 to Visual C++ 6.0/.Net. The company I work for has many products that must be upgraded. I hate to start from scratch if not necessary. Thanks for any info.

I know of no utilities, but would advise you to create the VS projects/solutions from scratch even if there were. In the past I've done way to many cross compiler "ports" (and even backward ports from VS 4/5/6 to VC++ 1.52c Eek! | :eek:

and even a "port" from OWL to MFC.)

The OWL to MFC port was the most difficult, especially since at the time, MFC didn't support reflection but OWL did. (For the record, everything else was easier in MFC and Visual C++ 1.52c was much more stable.)

If you need assistance, I'm available for moonlighting.... Smile | :)

(I'm one of those sickos who actually likes doing this, within reason [like my current job where we're just holding our collective noses and sticking with the convoluted combination of C, C++, MFC, STL, rolled-their-own-bizarro-partial-clone-of-ATL and mystery code.])

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

error PRJ0019: A tool returned an error code: Performing registration

Hi,

I am converting an VC 6.0 C++ DLL to ATL VC 7.0 DLL. I first converted the DLL to a VC 7.0 non-managed COM DLL. I tested this and everything works fine. Then I proceeded to add an ATL COM+ class to the project. The compiler compiles w/ no errors however it errors out when trying to regsvr32 the DLL w/ the following message...

[Performing registration
Project : error PRJ0019: A tool returned an error code from "Performing registration"]

What does it mean ???

Thanx & Regards,
Paul

I have exactly the same problem. If you look under the linker settings you probably have register output, as you would for an ATL project. Thing is this sets the post build event to run regsvr32 /s /c outputname. The ide interprets no output on the command line as being an error,. But /s silent was specified, hence why its confused. So in fact, it did register successfully, but took its silence as meaning something was wrong. Don't get me started on the /c, as its not even an option on regsvr32!

Personally can't see any way to fix it other than turning it off. So you have to regiser it yourself. Possibly, though have not tried it yet, is to pass it to a bat file, to echo something and keep it happy.

All I can say is VC++ team, fix this as its crap!!!!

If you allow me to rant on, another problem I've had recently is that even though I specify link to the Multithreaded debug dll version of the CRT, it will link to both the debug and release versions, giving me problems with heap allocation problems. Arrgh. You have to force it not to link. See LNK4098 I think.

And finally, wait until you see VS.NET get its knickers in a twist with Source Safe. Its really quite sad. Its like a whole load of stuff they have just not tested.

I wonder how I can find paint region of every window. You know that there a lot of windows with custom form (elipse, triangle, etc.).

Best regards,

You might consider e-mailing the authors of the RFC. They might have some code, or know of a link that does.

How to convert a integer value to CString

I want to convert a integer value to a CString.

I have been using 'itoa' or 'sprintf' to convert integer value to char string then convert the char string to CString.

Is there a better way to do it?
