  • stock management of assemblys and its sub parts

    - by The Disintegrator
    I have to track the stock of individual parts and kits (assembly) and can't find a satisfactory way of doing this. Sample bogus and hyper simplified database: Table prod: prodID 1 prodName Flux capacitor prodCost 900 prodPrice 1350 (900*1.5) prodStock 3 - prodID 2 prodName Mr Fusion prodCost 300 prodPrice 600 (300*2) prodStock 2 - prodID 3 prodName Time travel kit prodCost 1650 (1350+300) prodPrice 2145 (1650*1.3) prodStock 2 Table rels relID 1 relSrc 1 (Flux capacitor) relType 4 (is a subpart of) relDst 3 (Time travel kit) - relID 2 relSrc 2 (Mr Fusion) relType 4 (is a subpart of) relDst 3 (Time travel kit) prodPrice: it's calculated based on the cost but not in a linear way. In this example for costs of 500 or less, the markup is a 200%. For costs of 500-1000 the markup is 150%. For costs of 1000+ the markup is 130% That's why the time travel kit is much cheaper than the individual parts prodStock: here is my problem. I can sell kits or the individual parts, So the stock of the kits is virtual. The problem when I buy: Some providers sell me the Time Travel kit as a whole (with one barcode) and some sells me the individual parts (with a different barcode) So when I load the stock I don't know how to impute it. The problem when I sell: If I only sell kits, calculate the stock would be easy: "I have 3 Flux capacitors and 2 Mr Fusions, so I have 2 Time travel kits and a Flux Capacitor" But I can sell Kits or individual parts. I have to track the stock of the individual parts and the possible kits at the same time (and I have to compensate for the sell price) Probably this is really simple, but I can't see a simple solution. Resuming: I have to find a way of tracking the stock and the database/program is the one who has to do it (I cant ask the clerk to correct the stock) I'm using php+MySql. But this is more a logical problem than a programing one

  • Subclass not seeing superclass' instance variable

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? If I make this ivar a property then I can access it by self.x. What's worse is sometimes the error disappears, so something in my code is obviously causing this error but I cannot figure it out.

  • Silverlight vs web 2.0

    - by nathan gonzalez
    i understand that silverlight has come a long way since its inception, but i have always struggled to find the business need for silverlight. i'd love to hear the advantages and disadvantages of silverlight 4.0 vs modern html5 and javascript libraries like jQuery or ExtJS from some people who are more in the know than i am. is silverlight the way of the future or a stumbling block on the path to a plugin free web?

  • Help with Android LinearLayout or RelativeLayout

    - by PeEll
    I need to create two views programmatically (because I need to access the ondraw of one of the views). For some reason, no matter what I do to add the views to the contentview, they don't show up vertically stacked, one below the other. I can do it just fine using the XML using a RelativeLayout and layout positioning, but with the XML I can't create a view object and overload the ondraw method. What am I doing wrong with the programmatic approach, and how do I solve this problem? LinearLayout mLinearLayout; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Create a LinearLayout in which to add the ImageView mLinearLayout = new LinearLayout(this); TextView tv = new TextView(this); tv.setBackgroundColor(0xff333333); tv.setText("Enter your member number:"); tv.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); DrawableView i = new DrawableView(this); i.layout(0,40,0,0); i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mLinearLayout.addView(tv); mLinearLayout.addView(i,300,300); setContentView(mLinearLayout); }

  • Giving focus to GNOME docked window

    - by mike
    I've got a GTK/GDK docked window that I need to give keyboard focus to, so accelerator keys (shortcuts) work. Does anybody know if GNOME even allows a docked window to have keyboard focus, and if so, how can I enable it? Thanks, Mike

  • MSMQ on Win2008 R2 won’t receive messages from older clients

    - by Graffen
    Hi all I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Amazon EC2 php/fedora htaccess mod_rewrite not working

    - by wes
    Amazon EC2 with Fedora, there are 2 instances of the httpd conf, the doc root is automatically set as /home/webuser/helloworld/conf/httpd.conf and the default (which is also there) is /etc/httpd/conf/httpd.conf . Mod rewrite is enabled with both, we are in drupal, the .htaccess is in the folder it needs to be (on Drupal) and it loads the homepage and other static files fine, but it WILL not use htaccess. Any thoughts?

    - by stackoverflowuser
    Tool that can be used to migrate (or even better..synchronize) test cases and bugs between: TFS 2008 and Quality Center 9.2 (or later) TFS 2010 and Quality Center 9.2 (or later) I am aware of the following tools: Test Case Migrator (Excel/MHT) Tool TFS Bug Item Synchronizer 2.2 for Quality Center Also shai raiten mentions on his blog about QC 2 Team System 2010 migration tool that he has been working on and its done. But could not find any link for downloading the tool. http://blogs.microsoft.co.il/blogs/shair/archive/2009/12/31/quality-center-migration-to-team-system-2010-done.aspx Before jumping on coding with TFS SDK and QC components to come up with my own tool I need some inputs from the stackoverflow community.

What am I doing wrong. Thanks

  • How to change Winamp's default skin to Bento?

    - by TomatoSandwich
    If I install Winamp through automated means (e.g. Using http://ninite.com/), it is automatically installed using the default 'boxy' skin. I can't work out how to interface with this skin as easily as the new 'Bento' skin. In addition, there doesn't seem to be an option to download the Bento skin, or change the skin from Default to Bento without uninstalling and reinstalling it again. Is there a menu option or a downloadable skin that is the default Bento skin? Or do I have to re-install to get this 'new default' skin?

  • PHP sleep() excution sequence while echoeing.

    - by Babiker
    I have the following: echo time()."<br>"; sleep(1); echo time()."<br>"; sleep(1); echo time()."<br>"; I wrote the preceding code with intention to echo time()."<br>" ln 1,echo time()."<br>" ln 4, wait a final second and then echo the final time()."<br>". Altough the time bieng echoed is correct when it comes to the intervals between time(), all echo functions are echoeing after the total of the waiting period/parameters in each sleep function. This is how the script runs: Excutes. Waits 2 secons. echoes 1275540664 1275540665 1275540666 Notice the correct incrementation in time() being echoed. My question is why is it not behaving like expected to where it echoes, waits a second, echoes again, waits one final second and then echos the last parameter? I know my question is a little confusing due to my wording, but i will try my hardest to answer any comments regarding this, thanks.

Edit: Folks, I do not have control over how the data comes into the DropDownList - I cannot modify the SQL.
