There's an example here about halfway down the page that shows a value being stored in a NUMBER field (i.e, partno). Is that of any help?

DirectX SDK

Just a quick and probably stupid question. I am currently downloading the latest DirectX SDK, which I believe is for DX10. Would this require my end users to have DX10 installed or is it backwards compatible to lets say DX7?

I know users can simply download a newer version, or I can ship the redistritubles, but I don't want to do this if it can be helped.

Also, MSDN lists the minimum OS required for all the standard API functions, but there is no mention of any DX api's in there. Is there a similar documentation or even and add in to the MSDN?

if you develop with the DX10 SDK then you do need to run with DX10 runtime

I have never seen anything for directx at the api function level with regards to minimum OS requirements but microsoft does tell you what the minimum os is for DirectX
http://msdn.microsoft.com/directx/sdk/[^]

I believe for DX10 it says:
This SDK will install on Windows XP, Windows Server® 2003, Windows Vista RC2, and Windows Vista RTM using Visual Studio .NET 2003 or 2005.

sure, don't use them ! Cool | :cool:

if they've been marked as deprecated, it's to tell you that you shouldn't use it ; of course, an alternative way exist, and you have to find it (maybe documented directly in the deprecated stuff)

In your project settings you can define CRT_SECURE_NO_DEPRECATE which will disable all deprecation (not really a good idea)

or

In the files that are giving you the warning, use the

#pragma warning (disable : 4995)

Hope that helps.

this will only hide the warnings, but the code will remain "dangerous"

I agree - but if you insist on using DAO and insist on not having the warning appear, that is you only option AFAIK.

as i said in my previous post, if something is deprecated, it is because something better superseeded it.i have no knowledge on this particular point, buti'mpretty sure the deprecated stuff documentation talks about where to find the replacement solution...

C -- Copy float to string

17-Jan-07 9:41

OK... then what I had indicated is correct.

If he wants to use DAO, he will have to use one of the two solutions I gave. The other option is to rewrite all of his database parts of the code to use ADO which is the replacement for DAO, or use ODBC.

Just curious since I use DAO in some apps, and really didn't want to change them all to ADO at this time. Guess I was hoping you knew another trick.

Hi Friends,
I would like to know is there any otherway to copy a double to string in C.

I see that it can be done by using sprintf(.. , "%f", .. ) but I want to know anyother way to do this.

My problem is:

If i run the sprintf (.., "%f", .. ) on any machine in which has decimal point as , (comma) instead of a . (dot) (like French) it is converting . to , in the string even if the double value is having .(dot) . I don't want it to happen.

Ur help is highly appreciated..

Thanks a lot..

Regards,
Leela

~~std::istringstream ?~~

my mistake, this is C++. use ftoa() as an alternative, but never forget that the number is the number. your problem is a matter of representation (the decimal character - '.' or ',' - is not stored in the number itself)

You have to display the number, HOW the systems wants to show the number.

If you have problems with it, can can also replace the "," with a string replace. Roll eyes | :rolleyes:

I'm not certain that you can force sprintf to a certain representation ( . instead of , ) ?

Not until _sprintf_l() came along. That might not be an option for the OP, however.

If I understand you correctly, you want numbers formatted like 123,456.78 regardless of the locale. Is that correct?

Hi David,
I want the double to be stored into the integer string as with decimal point as dot (.) but NOT as a , comma.

But why would you want to do this for countries that format numbers differently?
