• Polishing an user interface

  - by elec

  Looking for examples of some "final touches" to enhance an existing (raw) user interface. I.e nothing related to the core functionalities of the application, but rather examples of all these little details which give an application a "polished" look (new fonts, change in layout, more descriptive labels...others ?) The target platform will be a mobile platform (android/iphone). Note that I'm severly graphically impaired regarding colour and shape combinations, so anything too sophisticated will probably pass me by completely ;)

• How can one check for a binary in the GAC in a WiX installer?

  - by Billy ONeal

  I have an application which depends on the Team Foundation Server "Object Model", and looks for such binaries in the GAC. This means that clients of the app need to install Visual Studio, or the standalone TFS object model in order to use the application. I would like the installer to detect that the TFS bits aren't installed, and fail to install appropriately if they are not. Is such a thing possible?

• SystemIO Exception when opening RFCOMM in Mono

  - by Chief A-G

  I have a Mono application which opens a RFCOMM connection (/dev/rfcomm0) but when I run as a user, I get a System.IO.IOException Interrupted system call. I'm running this on openSUSE 11.2. If I run the application under sudo, it works fine. I have added the dialup group to my user account so I'm not getting a permission denied error. I'm not sure if this is a Mono serial comms question or a permissions question for ServerFault.

• Javascript self contained sandbox events and client side stack

  - by amnon

  I'm in the process of moving a JSF heavy web application to a REST and mainly JS module application . I've watched "scalable javascript application architecture" by Nicholas Zakas on yui theater (excellent video) and implemented much of the talk with good success but i have some questions : I found the lecture a little confusing in regards to the relationship between modules and sandboxes , on one had to my understanding modules should not be effected by something happening outside of their sandbox and this is why they publish events via the sandbox (and not via the core as they do access the core for hiding base libary) but each module in the application gets a new sandbox ? , shouldn't the sandbox limit events to the modoules using it ? or should events be published cross page ? e.g. : if i have two editable tables but i want to contain each one in a different sandbox and it's events effect only the modules inside that sandbox something like messabe box per table which is a different module/widget how can i do that with sandbox per module , ofcourse i can prefix the events with the moduleid but that creates coupling that i want to avoid ... and i don't want to package modules toghter as one module per combination as i already have 6-7 modules ? while i can hide the base library for small things like id selector etc.. i would still like to use the base library for module dependencies and resource loading and use something like yui loader or dojo.require so in fact i'm hiding the base library but the modules themself are defined and loaded by the base library ... seems a little strange to me libraries don't return simple js objects but usualy wrap them e.g. : u can do something like $$('.classname').each(.. which cleans the code alot , it makes no sense to wrap the base and then in the module create a dependency for the base library by executing .each but not using those features makes a lot of code written which can be left out ... and implemnting that functionality is very bug prone does anyonen have any experience with building a front side stack of this order ? how easy is it to change a base library and/or have modules from different libraries , using yui datatable but doing form validation with dojo ... ? some what of a combination of 2+4 if u choose to do something like i said and load dojo form validation widgets for inputs via yui loader would that mean dojocore is a module and the form module is dependant on it ? Thanks .

  - by Steven Hardman

  I have a legacy application that I'm trying to interact with from a browser. The only supported method from the application vendor is by using a DDEPoke request. I'm having difficulty figuring out a simple way to perform such a request from a browser. I am open to any particular technology, be it javascript, a browser plugin, ActiveX/Java Applet, etc - the simpler the solution the better. Does anyone have a simple solution for this?
