• How do I detect what software is using the webcam on a Windows box (XP,Vista,7)

  - by burnt_hand

  The idea is that I want to build a small app that detects if the webcam is being used and by what. I have thought about seeing who has use of the Twain.dll somehow (like the way process explorer knows) It's for a security style app that picks out weird webcam behaviour. Ideally I would use C# as it's my strong point, but I'm guessing it won't be that nice.

• C++ book for a c# developer

  - by Eldila

  I am a c# developer which finds himself having to relearn c++. The last time I programmed in c++ was in school and am looking for good books as a refresher. I want something that assumes previous programming exposure and gets straight to the point. Is there a book similar to K&R for c++? I know the language is bloated so a book that covers a subset of c++ would be ideal.

• GridBagConstraints weightx and weighty values

  - by xdevel2000

  In many books weightx and weighty values are expressed in different ways: some says 0.0 to 1.0 other says 0 to 100 other say until 1000 I'm a lot confused. In the API these variables are double types so I think the first is correct but what does it meaning a value of 0.4 or 0.7? are percentage values, point values? relative of what?

• create backup file descriptor?

  - by BobTurbo

  stdinBackup = 4; dup2(0, stdinBackup); Currently I am doing the above to 'backup' stdin so that it can be restored from backup later after it has been redirected somewhere else. I have a feeling that I am doing a lot wrong? (eg arbitrarily assigning 4 is surely not right). Anyone point me in the right direction?

• How do I use the Google Maps API GPS sensor?

  - by renegadeofunk

  All I've been able to find is how to specify the sensor parameter: http://code.google.com/apis/maps/documentation/v3/#SpecifyingSensor But nowhere does it say how to actually USE it. Isn't the whole point to be able to get the user's current lat/long coordinates through the device GPS, or am I mistaken?

• Making many network shares appear as one

  - by jimbojw

  Givens: disk is cheap, and there's plenty lying around on various computers around the corporate intranet redundant contiguous large storage volumes are expensive Problem: It would be fantastic to have a single entry point (drive letter, network path) that presents all this space as one contiguous filesystem, effectively abstracting the disk and network architecture from the paths presented to users. Does anyone know how to implement such a solution? I'm open to Windows and non-windows solutions, free and proprietary.

• Force ClickOnce - application to be started offline?

  - by stormianrootsolver

  I have a click once application here that needs to be started offline exclusively sometimes. Reason is that it needs to be started VERY early during boot, at a point when there is no network connection yet, also it must not wait for any network connectivity. I know, this requirement seems strange, but it has legacy reasons. What do you think?
