  • Order of declaration in an anonymous pl/sql block

    - by RenderIn
    I have an anonymous pl/sql block with a procedure declared inside of it as well as a cursor. If I declare the procedure before the cursor it fails. Is there a requirement that cursors be declared prior to procedures? What other rules are there for order of declaration in a pl/sql block? This works: DECLARE cursor cur is select 1 from dual; procedure foo as begin null; end foo; BEGIN null; END; This fails with error PLS-00103: Encountered the symbol "CURSOR" when expecting one of the following: begin function package pragma procedure form DECLARE procedure foo as begin null; end foo; cursor cur is select 1 from dual; BEGIN null; END;

  • How to resize pdf graphics produced in R using Illustrator

    - by user1648516
    I am making plots in R using the pdf() command. Graphs look perfect and resize nicely in Acrobat Reader. My usual workflow includes manipulating labels etc. in Illustrator, saving as .eps for submission to publishers or inserting in Word. All works fine for single graphs. Now I am trying to combine 4 graphs into one by manually putting them together in an A4 Illustrator document. However, when I resize the standard 7x7 inches pdf graph in Illustrator to fit in one column of an A4 page (ca 3.4 inches wide), all proportions get screwed up, e.g. lines and symbols outlines become way too thick. Using pdf(..., width=3.4, height=3.4) in R messes up all the symbol and font sizes so carefully chosen to produce the original graph. Why can't I resize the graph within Illustrator the same way I can resize the pdf e.g. in Acrobat Reader?

  • Handling null values with PowerShell dates

    - by Tim Ferrill
    I'm working on a module to pull data from Oracle into a PowerShell data table, so I can automate some analysis and perform various actions based on the results. Everything seems to be working, and I'm casting columns into specific types based on the column type in Oracle. The problem I'm having has to do with null dates. I can't seem to find a good way to capture that a date column in Oracle has a null value. Is there any way to cast a [datetime] as null or empty?

  • Rendering Dragged object during drag

    - by marco
    Hello, I have been stuck on this problem for a while now. I want to drag a row in a jtable to reorder it. But I really want the user to see the row while dragging it and not just the default "drag" rectangle symbol. So I took a look at the java DnD tutorial finding it very useful, but.. The problem is that I still dont know which method I should override to get this going. Can somebody help me out?

  • How can i attach data to a JTA transaction? (or uniquely identify it)

    - by kwyjibo
    I have a getStockQuote() function that will get a current stock quote for a symbol from the stock market. My goal is that within a JTA transaction, the first call to getStockQuote() will fetch a stock quote, but all subsequent calls within the same transaction will reuse the same stock quote (e.g.: it will not try to fetch a new quote). If a different transaction starts, or another transaction runs concurrently, i would expect the other transaction to fetch its own stock quote on its first call. This would be similar to how you can configure JPA providers to only fetch a database row from the database once, and use the cached value for subsequent access to the same database row within the transaction. Does anyone have tips on how this can be achieved?

  • inserting datetimes into database using java

    - by gordatron
    Hi, I am wanting to insert a datetime into a MySql data base using Java and a prepared statement: Calendar cal = Calendar.getInstance(); PreparedStatement stmnt = db.PreparedStatement("INSERT INTO Run " + "(Time) VALUE (?) "); stmnt.setDate(1, new java.sql.Date(cal.getTime())); stmnt.executeQuery(); NOTE: thre is currently an error - cannot find symbol (java.sql.Date) line 4 here db is an instance of a sort of wrapper class that exposes what I need from java.sql - its just getting a prepared statement from my connection object here. Time (the column) is a date time in my database, and I can only see sedDate and setTime method but I want to store both - also my code does not work anyway ;-) if anyone could give me some pointers on inserting a combined date time (current time would be a great help as that's my first goal) into a MySql DB using a prepared statement I would be very grateful. Thanks

  • Accessing variablss through a different class within the constructor of latter classes of an object

    - by Haxed
    In the code below, I've added two lines that print output. The first line prints junk as usual, but surprisingly the second one gives me a compilation error. Why? class Student { private String name; public Student(String name){ this.name = name; } public String getName(){ return name; } } class StudentServer { public StudentServer(){ Student[] s = new Student[30]; s[0] = new Student("Nick"); // LINE 01: This compiles, although prints junk System.out.println(s[0]); // LINE 02: I get a error called cannot find symbol System.out.println(s[0].getName()); } public static void main(){ new StudentServer(); } } Many Thanks

  • Event is causing an error, but I can't catch the exception

    - by proudgeekdad
    A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line. Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound Try ProcessBadData... Catch ex As Exception Throw ex End Try End Sub In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. Any ideas how I can capture the exception in this ASCX control so I can report it to the user?

  • Debuggin in Xcode

    - by huggie
    I'm toying with iPhone app development. Often times I would run into runtime error and I would have no idea where the error occurs (e.g. the exact line). In console app with GCC I could at least compile with the -g flag. dump a core file and read that core file in to get to the last line that got into trouble. But how would I do that in Xcode? Build and Debug doesn't seem to have the debugging symbol loaded.

  • How to remove all words written in capital letters ONLY (by using sed and/or awk)

    - by Virtual_Lotos
    I am trying to delete all words written in capital letters only by using sed: sed -r "s/\b[A-Z]\w*\s*//g" < file1 > file2 But this solution capture all the words starting with capital letters and delete them (this in not the goal). Here's an example: file1 content: AAAAAAAAAAAA BBbbbbb AbAbAbAb aaaaaBBBBB AAAAAA BBBBBB A1-B1 a1-b1 A1-b1 AA AAAAA BBBBB AAAAA Abbbb AAA AAAAA AAAABB Abbbb Baaaa Aaaaa AB AAAAAA1 BBBBBBb AAAAAA 1 BBBBBB b Result should be like this (file2 content): BBbbbbb AbAbAbAb aaaaaBBBBB A1-B1 a1-b1 A1-b1 AA Abbbb AAA Abbbb Baaaa Aaaaa AB AAAAAA1 BBBBBBb AAAAAA 1 BBBBBB b Each line of at least one digit or one lowercase letter should remain intact (should not be deleted).

  • NoMethodError when trying to invoke helper method from Rails controller

    - by John Topley
    I'm getting a NoMethodError when trying to access a method defined in one of my helper modules from one of my controller classes. My Rails application uses the helper class method with the :all symbol as shown below: class ApplicationController < ActionController::Base helper :all . . end My understanding is that this should make all of my controller classes automatically include all of the helper modules within the app/helpers directory, therefore mixing in all of the methods into the controllers. Is this correct? If I explicitly include the helper module within the controller then everything works correctly.

  • Maintaining Logging and/or stdout/stderr in Python Daemon

    - by dave mankoff
    Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

  • Print unique ascii characters in eclipse console

    - by Shaded
    Hey guys, Kind of a strange question but... here it goes. Recently my application threw an IOException that the text only had a clubs symbol in it (like the suit in cards) I know this is probably because there was a number in there that was cast to a char and printed to the screen, and I've found where that might have happened. The only problem is, I can't recreate it in eclipse because the eclipse console doesn't want to print those characters for me. All I get are boxes. I figure this is an encoding issue or something but I need eclipse to print out those characters just like the windows console would. Is there a setting I can change to do this?

  • How to set Camera View as background with views over it?

    - by Android Student
    So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

  • scala xml rewrite rule (or, simple pattern help)

    - by williamstw
    I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim

  • Copy method optimization in compilers

    - by Dženan
    Hi All! I have the following code: void Stack::operator =(Stack &rhs) { //do the actual copying } Stack::Stack(Stack &rhs) //copy-constructor { top=NULL; //initialize this as an empty stack (which it is) *this=rhs; //invoke assignment operator } Stack& Stack::CopyStack() { return *this; //this statement will invoke copy contructor } It is being used like this: unsigned Stack::count() { unsigned c=0; Stack copy=CopyStack(); while (!copy.empty()) { copy.pop(); c++; } return c; } Removing reference symbol from declaration of CopyStack (returning a copy instead of reference) makes no difference in visual studio 2008 (with respect to number of times copying is invoked). I guess it gets optimized away - normally it should first make a copy for the return value, then call assignment operator once more to assign it to variable sc. What is your experience with this sort of optimization in different compilers? Regards, Dženan

  • How to display mysql records as preselected checkboxes?

    - by Jennifer
    I have a table column called post_tags within a table called posts where assigned tags are stored separated by the @ symbol. I also have a table called tags where all tag names are stored. I would like to design my database in a more normalized way but for the purpose I am trying to achieve this is the easiest option. Anyway, I want to display on the screen all the entries from the tags table as checkboxes, so I do: $query = mysql_query("SELECT * FROM tags ORDER BY name"); while ($row = mysql_fetch_assoc($query)) { $tag = $row['name']; echo "<input type='checkbox' name='tags[]' value='$tag' />\n"; } Next I want to have the tags that are assigned to a particular post be preselected. For example, if I have a post with the following in it's post_tags column: party@beaches@dolphins@ I want the "party", "beaches" and "dolphin" checkboxes to be checked by default (while the checkboxes for the other options are unchecked). How can this be done?

  • Best way to validate currency input?

    - by Abe Miessler
    I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

  • Backbone.js: How to utilize router.navigate to manipulate browser history?

    - by Xavier_Ex
    I am writing something like a registration process containing several steps, and I want to make it a single-page like system so after some studying Backbone.js is my choice. Every time the user completes the current step they will click on a NEXT button I create and I use the router.navigate method to update the url, as well as loading the content of the next page and doing some fancy transition with javascript. Result is, URL is updated which the page is not refreshed, giving a smooth user experience. However, when the user clicks on the back button of the browser, the URL gets updated to that of a previous step, but the content stays the same. My question is through what way I can capture such an event and currently load the content of the previous step and present that to the user? Or even better, can I rely on browser cache to load that previously loaded page? EDIT: in particular, I'm trying something like mentioned in this article.

  • How to compile using gcc but without using _alloca ?

    - by shkim
    For some reason, I should use gcc to compile a C file, then link against Visual C++ 2008 project. (I used the current latest gcc version: cygwin gcc 4.3.4 20090804.) But there is one problem: gcc always allocate a big array with _alloca, and VC linker can't resolve the symbol __alloca. for example, int func() { int big[10240]; .... } this code makes the _alloca dependency although I didn't call the _alloca function explicitly. (array size matters. if i change 10240 - 128, everything ok) I tried gcc option -fno-builtin-alloca or -fno-builtin, but no luck. Is it possible to make gcc not to use _alloca ? (or adjust the threshold?)
