  - by michael

  I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program. It needs to always start in the same place. Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery. I am not sure which properties I need to tweak to achieve all of this.

• Highlight table view cells when user drags across rows

  - by chronos

  I have a grouped table view that does not need to scroll. I'd like each cell to highlight as the user moves their finger down the screen and call didSelectRowAtIndexPath on release. This behaviour can be seen done by apple in 'settings mail add account'? I can't seem to replicate it myself, all I can get is the default, where the cell deselects as soon as the user moves their finger.

• How to use Unicode in C++?

  - by Dox

  Assuming a very simple program that: -ask a name. -store the name in a variable. -display the variable content on the screen. It's so simple that is the first thing that one learns. But my problem is that I don't know how to do the same thing if I enter the name using japanese characters.

  I would like to have in my Flex application the ability to post objects (for instance images or text items) where user can drag/drop for absolute positioning on the screen, resize it and rotate it (although not high priority).

• vim - open file with complete path

  - by David Oneill

  If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file? (preferably in a split screen) As I think about it, here is what I would like: if the file name contains a / character, assume it is a full path (IE the 'current directory' is root). Otherwise, use the current folder (IE default behavior) Is this possible?

• Activating a button underneath the mouse: how do you capture the OVER event?

  - by cgs

  Observed behavior: I have a page of UI sliding onto the screen. On slide complete, activate buttons. If mouse already over a button, the rollover does not happen (since MOUSE_OVER hasn't technically occurred) Desired behavior: 1, 2 the same, but on 3, I see my rollover. Is there any way to easily do this, aside from something brute-force, like tracking the mouse and comparing its position against all buttons dims? Thanks!
