  • Intents? How to register to be alerted for incoming emails?

    - by Justin
    Extreme Android developer newbie here...well, new to Android development, not development in general. I want to write an application that gets notified when emails come into the device, and takes various actions based on data in the email (subject, sender, to, etc). I think what I have to do is create a BroadcastReceiver with an IntentFilter. The problem I'm having is figuring out what Intent(s) I need to "listen" for. Can anyone point me in the right direction? Thanks.

  • Oracle: Is there a way to get the column data types for a view?

    - by rally25rs
    For a table in oracle, I can query "all_tab_columns" and get table column information, like the data type, precision, whether or not the column is nullable. In SQL Developer or TOAD, you can click on a view in the GUI and it will spit out a list of the columns that the view returns and the same set of data (data type, precision, nullable, etc). So my question is, is there a way to query this column definition for a view, the way you can for a table? How do the GUI tools do it?

  • Is ASP.net MVC a direct copy of Ruby on Rails concepts?

    - by Greg
    Hi, I'm been developing Ruby on Rails previously. I'm now looking at an ASP.net web app and I'm looking at WebForms and MVC. As I look at MVC it feels as if I'm looking at the result of something a Ruby on Rails developer implemented after being forced to work in MS land. So I'm wondering: Was MVC more or less taken directly from Ruby on Rails and it's concepts? (either intentionally or unintentionally)

  • Share your conky tips / scripts / .conkyrc

    - by Chad Birch
    I've just started tinkering with conky, and I'm hoping the StackOverflow crowd can share some of the cool things they've done with this tool. Scripts and .conkyrc files specifically geared towards developers would be especially good to see. Some good examples of developer-centric functions would be repository-monitors or heck, even something that monitors StackOverflow. Screenshots of what the functionality actually looks like would be appreciated as well.

  • HTTP Proxy with monitor UI for local install

    - by zedoo
    Hi, I'm looking for an HTTP Proxy/GUI combination that should be installed locally on my Windows PC. The UI should display something similar to Firebugs "Network" tab, showing request/response headers and content as plaintext. It would be cool if I could attach requests to a sort of node for later comparison, similar to what you can do when using the Proxy that comes with JMeter.

  • Sorting a List based on an ArrayList within a custom Object

    - by Matt Weldon
    I am using a list to keep track of a number of custom Row objects as follows: Public Rows As List(Of Row)() Row has 2 properties, Key (a String) and Cells (an ArrayList). I need to be able to sort each Row within Rows based on a developer defined index of the Cells ArrayList. So for example based on the following Rows Row1.Cells = ("b", "12") Row2.Cells = ("a", "23") Rows.Sort(0) would result in Row2 being first in the Rows list. What would be the best way of going about implementing this? Thanks

  • block write access to table from an application in mysql

    - by hoberion
    Hello, We have a CMS plugin that writes statistics to 1 table, this creates performance issues on the entire platform. We decided to use another statistics plugin which can connect to a different database server (the first plugin couldn't!) however we need parts of the first plugin. I want to lock the statistics table to prevent misusage (not allowed to drop it by the developer) So I was wondering if a lock table could do this or if I can implement some sort of read only table

  • Determining if Memory Pointer is Valid - C++

    - by Jim Fell
    It has been my observation that if free( ptr ) is called where ptr is not a valid pointer to system-allocated memory, an access violation occurs. Let's say that I call free like this: LPVOID ptr = (LPVOID)0x12345678; free( ptr ); This will most definitely cause an access violation. Is there a way to test that the memory location pointed to by ptr is valid system-allocated memory? It seems to me that the the memory management part of the Windows OS kernel must know what memory has been allocated and what memory remains for allocation. Otherwise, how could it know if enough memory remains to satisfy a given request? (rhetorical) That said, it seems reasonable to conclude that there must be a function (or set of functions) that would allow a user to determine if a pointer is valid system-allocated memory. Perhaps Microsoft has not made these functions public. If Microsoft has not provided such an API, I can only presume that it was for an intentional and specific reason. Would providing such a hook into the system prose a significant threat to system security? Situation Report Although knowing whether a memory pointer is valid could be useful in many scenarios, this is my particular situation: I am writing a driver for a new piece of hardware that is to replace an existing piece of hardware that connects to the PC via USB. My mandate is to write the new driver such that calls to the existing API for the current driver will continue to work in the PC applications in which it is used. Thus the only required changes to existing applications is to load the appropriate driver DLL(s) at startup. The problem here is that the existing driver uses a callback to send received serial messages to the application; a pointer to allocated memory containing the message is passed from the driver to the application via the callback. It is then the responsibility of the application to call another driver API to free the memory by passing back the same pointer from the application to the driver. In this scenario the second API has no way to determine if the application has actually passed back a pointer to valid memory.

  • Is there any way to identify a unique user in Flash/Actionscript 3?

    - by VGambit
    I'm trying to make a vote/poll application in Flash using Actionscript 3. Is there any way to generate a specific ID that is unique to each user? The only other option I can think of is using the IP address, which is less than ideal in many cases (college campuses, shared Internet access, etc.). It needs to be the same number every time it is run on the same PC, but different for each user.
