Thanks for writing. But I do not want to develop a licensing system, I rather want to use a 3rd party solution, which may include a hosted licensing server as well, that handles the key generation & key management stuff. Regards,

Hi All, I need some advice on licensing softwares availabe in the market. I should be able to check if a specific feature is available on a specific product, using some feature id or something, from within code obv. I need it to work for native C++ apps as well as managed apps in C#. I have seen a couple of softwares but they either cater native or managed. Some go a step further and try to have their software work with the env. it is not meant for, but you have to compromise things. E.g. using a C++ piece for C#, by exporting it via a DLL, but you compromise security here as compared to a LIB based solution, as anybody can hook into the DLL and stuff. Similalry .NET solutions can be used in C++, but requires building the projects with /clr. I also want to be able to do the activation/deactivation/license updates online and offline, both. I would appreciate any recommendations. Regards,

rotation is given by a unit vector (ax, ay, az) and the angle theta is in radians

I believe I have theta, but I dont see any vector provided along with in the information object that I have. All it says is "angle in radians rotated from +ve world x-axis". Does this indicate any default vector that I can use for this conversion?

Yes you are right, its to be used in 3D. I am not good in this domain. The docs for that double value say "angle in radians rotated from +ve world x-axis". Does this indicate something ? update: Now I understand that I need a vector, along with the angle for the conversion, but that vector is no where to seen in the information object for the text box. Is ther anything I can use as default for +ve world x-axis as it says above.

Hi, I have a double value describing rotation angle for a text box object. I need to convert it to quaternion. I have searched the web, and all I get is converters that conver Euler angle to Quaternion. I would appreciate any formulae or algorithm. And this double value is the only information I have for rotation. Regards, Shoaib

The most ridicoluos ad line I have ever seen. I just saw an ad of VSoft on CP telling: "At VSoft we hire chimps to write build scripts... so you don't have to." Can you expect a software company calling its developers as code monkeys, thats just stupid. And they are proud of this advertising compaign as some mr. Brent is saying on his blog[^] God help the poor devs.

On the same link it says: Requirements * Operating System: Windows Vista 32bit / 64bit (on x64, only 32-bit (Wow64) processes are supported) * Development Tools: Visual Studio 2010 Team Suite, Team Test, Team Dev Editions But yes, if VS 2010 isnt out yet, why its tools then?

If you are using the same file object to read the file again, you need to seek the file pointer to beginning of file(BOF), before you read. This is so because you have read to End of File, and when you read again, it tries to read from current position of file pointer. You need to reset the current position to BOF. I dont know what language are u using but it would be something like file.Seek(0); or filestream.SeekBegin(); or something similar. Regards,

May be you should try Tools->Options->Environment->International Settings and setting your language there. You may need to set Arabic for your OS, in control panel first.

As Cedric said, you need to pump your messages, while you are busy doing something else. This means you need to add a message loop to your class , and call the loop several times while you are through a long process, to let all the awaiting messages come up. Something like MSG msg; while (PeekMessage(&msg ...)) { TranslateMessage(&msg); DispatchMessage(msg); }
