15,862,443 | 0 | Populate cells with two numbers only using vba <p>Please help me, what I am trying to do is to populate cells N2:N1041 with numbers 0 and 2. I want total of 100 cells (random cells to be filled in) in column N to be populated with "0" and the remaining 940 cells to have "2". Or in other words, I want the 9.6% of the range (N2:N1041) to be filled with "0" and the rest with "2".</p> <p>Thank you so much in advance. </p> |

That's intentional, to distinguish the <code>dtype</code> records from a row of a 2d (ordinary) array.</p> <p>That also means that when creating the array, or assigning values, you also need to use a list of tuples.</p> <p>For example let's make a list of lists:</p> <pre><code>In [554]: ll = np.arange(9).reshape(3,3).tolist() In [555]: ll In [556]: A[:]=ll ... TypeError: a bytes-like object is required, not 'list' </code></pre> <p>but if I turn it into a list of tuples:</p> <pre><code>In [557]: llt = [tuple(i) for i in ll] In [558]: llt Out[558]: [(0, 1, 2), (3, 4, 5), (6, 7, 8)] In [559]: A[:]=llt In [560]: A Out[560]: array([(0.0, 1.0, 2.0), (3.0, 4.0, 5.0), (6.0, 7.0, 8.0)], dtype=[('MSFT', '<f8'), ('CSCO', '<f8'), ('GOOG', '<f8')]) </code></pre> <p>assignment works fine. That list also can be used directly in <code>array</code>.</p> <pre><code>In [561]: np.array(llt, dtype=dt) Out[561]: array([(0.0, 1.0, 2.0), (3.0, 4.0, 5.0), (6.0, 7.0, 8.0)], dtype=[('MSFT', '<f8'), ('CSCO', '<f8'), ('GOOG', '<f8')]) </code></pre> <p>Similarly assigning values to one record requires a tuple, not a list:</p> <pre><code>In [563]: A[0]=(10,12,14) </code></pre> <p>The other common way of setting values is on a field by field basis. That can be done with a list or array:</p> <pre><code>In [564]: A['MSFT']=[100,200,300] In [565]: A Out[565]: array([(100.0, 12.0, 14.0), (200.0, 4.0, 5.0), (300.0, 7.0, 8.0)], dtype=[('MSFT', '<f8'), ('CSCO', '<f8'), ('GOOG', '<f8')]) </code></pre> <p>The <code>np.rec.fromarrays</code> method recommended in the other answer ends up using the copy-by-fields approach.

15,120,243 | 0 | <p>Easiest example I can think of would be a method that sends some content to a JMS server. If you are in the context of a transaction, you want the message to be coupled to the transaction scope. But if there isn't already a transaction running, why bother calling the transaction server also and starting one just to do a one-off message?</p> <p>Remember these can be declared on an API as well as an implementation. So even if there isn't much difference for your use case between putting it there and putting nothing there, it still adds value for an API author to specify what operations are able to be included in a transaction, as opposed to operations that perhaps call an external system that does not participate in transactions.</p> <p>This is of course in a JTA context. The feature doesn't really have much practical use in a system where transactions are limited to resource-local physical database transactions.</p> |

If you have a phone with a dedicated PTT button, the manufacturer of the phone almost certainly has made an Intent available for app developers such as yourself to intercept PTT down and up events, but you'll need to contact the manufacturer for more information.</p> <p>For instance, phones from Kyocera, Sonim, and Casio have such Intents available, and you'd simply need to put a receiver declaration in your AndroidManifest.xml, like this for a Kyocera phone:</p> <pre><code> <receiver android:exported="true" android:name="com.myapp.receiver.KeyReceiverKyocera"> <intent-filter android:priority="9999999"> <action android:name="com.kodiak.intent.action.PTT_BUTTON" /> <action android:name="com.kyocera.android.intent.action.PTT_BUTTON" /> </intent-filter> </receiver> </code></pre> <p>Then, a simple BroadcastReceiver class that receives the up and down intents:</p> <pre><code>public class KeyReceiverKyocera extends BroadcastReceiver { private static boolean keyDown = false; @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (keyDown) processPTTDown(); else processPTTUp(); keyDown = !keyDown; } } </code></pre> <p>Hope this helps,</p> <p>Shawn</p> |

6,262,010 | 0 | <p>Okay, this answer is SQL Server specific, but should be adaptable to other RDBMSs, with a little work. So far as I see, we have the following constraints:</p> <ul> <li>An invoice may be associated with 0 or 1 Work Orders</li> <li>A Work Order must be associated with an invoice or an ABC or a DEF</li> </ul> <p>I'd design the WorkOrder table as follows:</p> <pre><code>CREATE TABLE WorkOrder ( WorkOrderID int IDENTITY(1,1) not null, /* Other Columns */ InvoiceID int null, ABCID int null, DEFID int null, /* Etc for other possible links */ constraint PK_WorkOrder PRIMARY KEY (WorkOrderID), constraint FK_WorkOrder_Invoices FOREIGN KEY (InvoiceID) references Invoice (InvoiceID), constraint FK_WorkOrder_ABC FOREIGN KEY (ABCID) references ABC (ABCID), /* Etc for other FKs */ constraint CK_WorkOrders_SingleFK CHECK ( CASE WHEN InvoiceID is null THEN 0 ELSE 1 END + CASE WHEN ABCID is null THEN 0 ELSE 1 END + CASE WHEN DEFID is null THEN 0 ELSE 1 END /* + other FK columns */ = 1 ) ) </code></pre> <p>So, basically, this table is constrained to only FK to one other table, no matter how many PKs are defined. If necessary, a computed column could tell you the "Type" of item that this is linked to, based on which FK column is non-null, or the type and a single int column could be real columns, and InvoiceID, ABCID, etc could be computed columns.</p> <p>The final thing to ensure is that an invoice only has 0 or 1 Work Orders. If your RDMBS ignores nulls in unique constraints, this is as simple as applying such a constraint to each FK column. For SQL Server, you need to use a filtered index (>=2008) or an indexed view (<=2005). I'll just show the filtered index:</p> <pre><code>CREATE UNIQUE INDEX IX_WorkItems_UniqueInvoices on WorkItem (InvoiceID) where (InvoiceID is not null) </code></pre> <hr> <p>Another way to deal with keeping WorkOrders straight is to include a WorkOrder type column in WorkOrder (e.g. 'Invoice','ABC','DEF'), including a computed or column constrained by check constraint to contain the matching value in the link table, and introduce a second foreign key:</p> <pre><code>CREATE TABLE WorkOrder ( WorkOrderID int IDENTITY(1,1) not null, Type varchar(10) not null, constraint PK_WorkOrder PRIMARY KEY (WorkOrderID), constraint UQ_WorkOrder_TypeCheck UNIQUE (WorkOrderID,Type), constraint CK_WorkOrder_Types CHECK (Type in ('INVOICE','ABC','DEF')) ) CREATE TABLE Invoice_WorkOrder ( InvoiceID int not null, WorkOrderID int not null, Type varchar(10) not null default 'INVOICE', constraint PK_Invoice_WorkOrder PRIMARY KEY (InvoiceID), constraint UQ_Invoice_WorkOrder_OrderIDs UNIQUE (WorkOrderID), constraint FK_Invoice_WorkOrder_Invoice FOREIGN KEY (InvoiceID) references Invoice (InvoiceID), constraint FK_Invoice_WorkOrder_WorkOrder FOREIGN KEY (WorkOrderID) references WorkOrder (WorkOrderID), constraint FK_Invoice_WorkOrder_TypeCheck FOREIGN KEY (WorkOrderID,Type) references WorkOrder (WorkOrderID,Type), constraint CK_Invoice_WorkOrder_Type CHECK (Type = 'INVOICE') ) </code></pre> <p>The only disadvantage to this model, although closer to your original proposal, is that you can have a work order that isn't actually linked to any other item (although it claims to be for an e.g INVOICE).</p> |

18,563,702 | 0 | Eclipse Plug-in Enable/Disable Menu Items Programatically <p>I am writing an eclipse plug-in that extends <em>AbstractDebugView</em>. </p> <p>My plugin has one context menu item, one pull-down menu item, and one toolbar menu item. The action associated with these menu items is a class I created (<em>CopyAction</em>) which extends <em>org.eclipse.jface.action.Action</em>.</p> <pre class="lang-java prettyprint-override"><code>public class CopyAction extends Action { private String text; private String toolTipText; private boolean enabled; private ImageDescriptor imageDescriptor; ... public CopyAction() { text = "Copy"; toolTipText = "Copy Action"; enabled = false; imageDescriptor = ...; } ... @Override public void setEnabled(boolean enabled) { this.enabled = enabled; } @Override public boolean isEnabled() { return enabled; } ... } </code></pre> <p>Note that by default my action is disabled (enabled = false).</p> <p>In my plug-in main view class I create and add the copy action to each of the menus:</p> <pre class="lang-java prettyprint-override"><code>public class MyDebugView extends AbstractDebugView { CopyAction copyAction; ... @Override protected Viewer createViewer(Composite parent) { // do some stuff to create the viewer content createActions(); fillLocalPullDown(); ... } @Override protected void createActions() { copyAction = new CopyAction(); } private void fillLocalPullDown() { IActionBars bars = getViewSite().getActionBars(); bars.getMenuManager().add(copyAction); } @Override protected void fillContextMenu(IMenuManager manager) { manager.add(copyAction); } @Override protected void configureToolBar(IToolBarManager manager) { manager.add(copyAction)); } } </code></pre> <p>Everything works great up to this point. When I test my plug-in I can see the context menu, the toolbar menu, and the pull-down menu.</p> <p>All the menu items are disabled, as I would expect since the constructor for <em>CopyAction</em> sets enabled = false;</p> <p>What I want to do is enable the menu items when a selection has changed in my plug-in view (which happens to be a <em>TreeViewer</em>). In the callback for the tree selection I do the following:</p> <pre class="lang-java prettyprint-override"><code>private class MySelectionChangedListener implements ISelectionChangedListener { public void selectionChanged(SelectionChangedEvent event) { // determine if the copy action should be enabled ... copyAction.setEnabled(true) } } </code></pre> <p>The issue I am running into is that even though I set enabled to true on <em>copyAction</em> the menu items do not become enabled.</p> <p>My suspicion as to what's happening is even though I set the enabled property to true nothing happens because the menu(s) need to be notified that the property has changed. Is there some method I have to call to <em>force</em> the menu managers to update themselves thereby checking the enabled property of the copy action?</p> <p>====</p> <p>I have been thinking about the way I have been coding my plug-in and researching the internet on how to add/enable/disable menu items to an Eclipse plug-in. Nearly all of the examples I have seen use <em>plugin.xml</em> to add the menu contributions instead of doing it programatically. (Most also use commands, not actions.) I have also seen where you can enable/disable/hide/show menus using property testers also configured in <em>plugin.xml</em>.</p> <p>Should I just drop the way I am doing things now and do it using the plugin descriptor and property testers? I hate to throw away all the work I have done up to this point but it's more important for me to do it right rather than fuss over time spent.</p> |

4,046,286 | 0 | <p>One technique that's common (especially in older editors) is called a split buffer. Basically, you "break" the text into everything before the cursor and everything after the cursor. Everything before goes at the beginning of the buffer. Everything after goes at the end of the buffer.</p> <p>When the user types in text, it goes into the empty space in between without moving any data. When the user moves the cursor, you move the appropriate amount of text from one side of the "break" to the other. Typically there's a lot of moving around a single area, so you're usually only moving small amounts of text at a time. The biggest exception is if you have a "go to line xxx" kind of capability.</p> <p>Charles Crowley has written a much more complete <a href="http://www.cs.unm.edu/~crowley/papers/sds/sds.html">discussion of the topic</a>. You might also want to look at <a href="http://www.finseth.com/craft/index.html">The Craft of Text Editing</a>, which covers split buffers (and other possibilities) in much greater depth.</p> |

However, this also resets 'FNR' to '1', so awk will skip processing the 'FNR==NR' block for file2 because it is not longer true.</p> <p>So for file2: if column '2' can be found in the array mentioned above:</p> <blockquote> <p>Split the value of the array element into another array. This essentially splits up the whole line in file1.</p> <p>Now create two loops.</p> <blockquote> <p>The first will loop through all the names in file2</p> <p>And the second will loop through all the values in the (second) array (this essentially loops over all the fields in file1).</p> </blockquote> <p>Now when a value succeeding a name in file2 is equal to one of the key numbers in file1, create a line construct that looks like: 'name:number_following_key_number_from_file1'.</p> <p>When more names and values are found during the loops, the quaternary construct '( ... ? ... : ...)' adds these elements onto the end of the line. It's like an if statement; if there's already a line, add a comma onto the end of it, else don't do anything.</p> <p>When all the loops are complete, print out column '1' and the line. Then empty the line variable so that it can be used again.</p> </blockquote> </blockquote> <p>HTH. Goodluck.</p> |

27,336,085 | 0 | jar built with jwrapper doesn't work <p>jwrapper manipulates application jars somehow, and is resulting in a non-functioning jar: at runtime it throws a "MyClass cannot be cast to MyClass" type error. I believe this is caused by re-evaluating code that creates a class loader, leading to multiple instances of class MyClass being loaded.</p> <p>The jwrapper docs don't describe the changes made to the jar, except for the use of pack200. I've tested pack200 in isolation, and it does not cause this problem.</p> <p>I've also tested the jar built by jwrapper without using the wrapper executable, by passing it to "java -jar". So it's not jvm transmuting, or anything else that the wrapper is doing: the jar itself is broken.</p> <p>UPDATE:</p> <p>jwrapper allows skipping pack200, but then the install file is huge. Since pack200 works when run standalone, I could work around this if there were some way to tell jwrapper that the file is already packed. Using <Pack200Exceptions> doesn't help, because then it doesn't know the file is packed.</p> |

1,753,357 | 0 | Per-file enabling of scope guards <p>Here's a little problem I've been thinking about for a while now that I have not found a solution for yet.</p> <p>So, to start with, I have this function guard that I use for debugging purpose:</p> <pre><code>class FuncGuard { public: FuncGuard(const TCHAR* funcsig, const TCHAR* funcname, const TCHAR* file, int line); ~FuncGuard(); // ... }; #ifdef _DEBUG #define func_guard() FuncGuard __func_guard__( TEXT(__FUNCSIG__), TEXT(__FUNCTION__), TEXT(__FILE__), __LINE__) #else #define func_guard() void(0) #endif </code></pre> <p>The guard is intended to help trace the path the code takes at runtime by printing some information to the debug console. It is intended to be used such as:</p> <pre><code>void TestGuardFuncWithCommentOne() { func_guard(); } void TestGuardFuncWithCommentTwo() { func_guard(); // ... TestGuardFuncWithCommentOne(); } </code></pre> <p>And it gives this as a result:</p> <pre> ..\tests\testDebug.cpp(121): Entering[ void __cdecl TestGuardFuncWithCommentTwo(void) ] ..\tests\testDebug.cpp(114): Entering[ void __cdecl TestGuardFuncWithCommentOne(void) ] Leaving[ TestGuardFuncWithCommentOne ] Leaving[ TestGuardFuncWithCommentTwo ] </pre> <p>Now, one thing that I quickly realized is that it's a pain to add and remove the guards from the function calls. It's also unthinkable to leave them there permanently as they are because it drains CPU cycles for no good reasons and it can quickly bring the app to a crawl. Also, even if there were no impacts on the performances of the app in debug, there would soon be a flood of information in the debug console that would render the use of this debug tool useless.</p> <p>So, I thought it could be a good idea to enable and disable them on a per-file basis.</p> <p>The idea would be to have all the function guards disabled by default, but they could be enabled automagically in a whole file simply by adding a line such as</p> <pre><code>EnableFuncGuards(); </code></pre> <p>at the top of the file.</p> <p>I've thought about many a solutions for this. I won't go into details here since my question is already long enough, but let just say that I've tried more than a few trick involving macros that all failed, and one involving explicit implementation of templates but so far, none of them can get me the actual result I'm looking for.</p> <p>Another restricting factor to note: The header in which the function guard mechanism is currently implemented is included through a precompiled header. I know it complicates things, but if someone could come up with a solution that could work in this situation, that would be awesome. If not, well, I certainly can extract that header fro the precompiled header.</p> <p>Thanks a bunch in advance!</p> |

Where do I find this file, so that I can add those three lines?</p> <p>Also, what does he mean by <code>reload your start up file (e.g. source .zshrc)</code>?</p> <p>I would appreciate a detailed response, specific to OSX.</p> |
