  • Where is the JTree definition for eclipse's Project Explorer?

    - by Jim
    Hello, The JTree implementation / Renderer used in eclipse (see the navigation pane on the left side) is extremely good. I've checked out the eclipse source code and am looking through it, but can't seem to find the reference to the JTree used. Does anyone know which package contains the definition of this pane? Thanks!

  • Calculating ComboBox DropDownWidth in C#

    - by Jim Fell
    In my application a ComboBox gets resized, so that it is smaller. How do I re-calculate the DropDownWidth property? I know how to set it, but I'd prefer to calculate the proper width because its contents changes. Preferabley, I was thinking of something along these lines: int iMaxLen = 0; foreach item in comboBoxList { iMaxLen = (item.Length > iMaxLen) ? item.Length : iMaxLen; } comboBoxList.DropDownWidth = iMaxLen; Thanks.

  • DLL with JNA error looking up function?

    - by Thomas Nappo
    This is the code in my DLL (C#): http://pastebin.com/Uirn0z2V I have the DLL built and inside both the JDK bin folder along with inside my project. This is the Java code I am using to access with JNA: http://pastebin.com/NffpaEp8 Yet when I run my Java code this happens: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'Run': The specified procedure could not be found. at com.sun.jna.Function.<init>(Function.java:179) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:391) at com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:371) at com.sun.jna.Library$Handler.invoke(Library.java:205) at $Proxy0.Run(Unknown Source) at RunPETest.main(RunPETest.java:18) I have no experience with using JNA with custom DLLs or creating DLLs with C#... so I'm stuck here.

  • sendmail and MX records when mail server is not on web host

    - by Jim Nelson
    This is a problem I'm sure is easy to fix, but I've been banging my head on it all day. I'm developing a new web site for a client. The web site resides at (this is an example) website.com. I have a PHP form script to email visitors' requests to [email protected]. When I coded this on a staging server on a different domain, all worked fine. When I moved it to website.com, the mail messages never arrived. The web server is on a virtual host with a major ISP. Here's what I've learned since then: My client's mail server is Microsoft Exchange on a box physically in their office. Whenever someone on the outside world emails [email protected], the mail arrives. But if the web server sends to the same email address, it fails every time. This is not a PHP problem. I secure shell in to the web server and have tested this both with sendmail and the UNIX mail application. I've also tested it by emailing various email accounts from the shell. I can email myself, for example, just nobody at the website.com domain. In short, when I'm logged in to website.com, mail to [email protected], [email protected], [email protected] all fail. All other addresses work fine. What I've discovered is those dropped emails are routed to the web server's "catchall" account where they sit in its inbox. I've done an MX lookup on website.com. The MX record points to mailsec.website.com. I can telnet to mailsec.website.com port 25 and see the SMTP server. It appears to me that website.com isn't doing an MX lookup when it's sending mail to [email protected]. My theory is that it recognizes the domain as local, sees that there's no "requests" user account to deliver it to, and drops the mail into the catchall account. What I want is to force sendmail to do the MX lookup and send the message on to the Exchange server. I'm at wit's end here. I can't figure out how to do this. For that matter, I may be way off base here and have misdiagnosed this entirely. Internet mail and MX has always seemed a black art to me, and my ignorance is certainly showing in this question.

  • What data formats does PowerShell most easily read ?

    - by Jim
    I'm trying to use PowerShell with SharePoint. I'd like my PowerShell scripts to load my SharePoint farm configuration from files rather than either hard coding the configuration in the scripts, or having to pass in the same parameters each time. This the kind of information I need to store. WebFrontEnds: Web1, Web2, Web3 CentralAdmin: Central1 Index: Web1 ContentWebApps: http://user1, http://user2 Does PowerShell easily load this data from CSV, XML, or other formats?

  • Why doesn't gcc remove this check of a non-volatile variable?

    - by Thomas
    This question is mostly academic. I ask out of curiosity, not because this poses an actual problem for me. Consider the following incorrect C program. #include <signal.h> #include <stdio.h> static int running = 1; void handler(int u) { running = 0; } int main() { signal(SIGTERM, handler); while (running) ; printf("Bye!\n"); return 0; } This program is incorrect because the handler interrupts the program flow, so running can be modified at any time and should therefore be declared volatile. But let's say the programmer forgot that. gcc 4.3.3, with the -O3 flag, compiles the loop body (after one initial check of the running flag) down to the infinite loop .L7: jmp .L7 which was to be expected. Now we put something trivial inside the while loop, like: while (running) putchar('.'); And suddenly, gcc does not optimize the loop condition anymore! The loop body's assembly now looks like this (again at -O3): .L7: movq stdout(%rip), %rsi movl $46, %edi call _IO_putc movl running(%rip), %eax testl %eax, %eax jne .L7 We see that running is re-loaded from memory each time through the loop; it is not even cached in a register. Apparently gcc now thinks that the value of running could have changed. So why does gcc suddenly decide that it needs to re-check the value of running in this case?

  • Why does jquery leak memory so badly?

    - by Thomas Lane
    This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple test pages for experimenting. Both pages do an ajax call every .1 seconds. After each successful ajax call, a counter is incremented and the DOM is updated. The script stops after 1000 cycles. One uses jquery for both the ajax call and to update the DOM. The other uses the Yahoo API for the ajax and does a document.getElementById(...).innerHTML to update the DOM. The jquery version leaks memory badly. Running in drip (on XP Home with IE7), it starts at 9MB and finishes at about 48MB, with memory growing linearly the whole time. If I comment out the line that updates the DOM, it still finishes at 32MB, suggesting that even simple DOM updates leak a significant amount of memory. The non-jquery version starts and finishes at about 9MB, regardless of whether it updates the DOM. Does anyone have a good explanation of what is causing jquery to leak so badly? Am I missing something obvious? Is there a circular reference that I'm not aware of? Or does jquery just have some serious memory issues? Here is the source for the leaky (jquery) version: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); </script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { $.ajax({ url: '/html/delme.x', type: 'GET', success: incrementCounter }); } function incrementCounter(data) { if (counter<1000) { counter++; $('#counter').text(counter); setTimeout(leakTest,100); } else $('#counter').text('finished.'); } </script> </head> <body> <div>Why is memory usage going up?</div> <div id="counter"></div> </body> </html> And here is the non-leaky version: <html> <head> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/connection/connection_core-min.js"></script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { YAHOO.util.Connect.asyncRequest('GET', '/html/delme.x', {success:incrementCounter}); } function incrementCounter(o) { if (counter<1000) { counter++; document.getElementById('counter').innerHTML = counter; setTimeout(leakTest,100); } else document.getElementById('counter').innerHTML = 'finished.' } </script> </head> <body> <div>Memory usage is stable, right?</div> <div id="counter"></div> </body> </html>

  • Converting String^ and Collection of String^ to const char*

    - by Jim Jones
    Using VS2008 Managed C++ to wrap a dll. The native method takes a series of single const char* values and a collection of char* values. Going to make an example function: Function1(char * value1, TF_StringList& catList); TF_StringList is a dll class with 3 insert methods, the one I want to use is: TF_StringList::insert(const char* str); So I set up a wrapper method of: WrapperClass::callFunction(String^ mvalue1, ArrayList mcatList); mvalue1 is converted to const char* using: const char* value1 = (char*)(Marshal::StringToHGlobalAnsi(mvalue1)).ToPointer(); However, when a get to the collection of strings, I iterate over it getting each string using the index: String^ mstr = mcatList[i]; Have tried every way of converting String^ to const char* and in every case the TF_StringList::insert(const char* str) method throws a C2663 error which has to do with the const-ness of the value. What is the problem?

  • SVN Path Based Authorization: Granting listing access but not read access

    - by Jim
    Hello, We're using path-based-authorization module for Apache SVN. It all works fine, except that when users try to check out code they have access to, their SVN clients get confused if they don't have at least read access to the parent directories - all the way up to root. It works, but some clients just get confused sometimes. Because SVN path-based-authorization is recursively applied, we don't want to give all users read access to root, because that would give them access to all source code in the repository. It would, however, be acceptable if users could get directory listings (just not actual lines of code) for the entire repository. This would prevent the svn clients from getting confused. Does any one know how to grant permissions to get directory listings without granting permissions to the actual contents of the files? Thanks!

  • Is there a way to programatically popup the "Microsoft Silverlight Configuration" dialog?

    - by Jim McCurdy
    I am building for Silverlight 4, and I handle MouseRightButtonDown events and build my own ContextMenu's (a class from the Silverlight Toolkit). I would like to add the classic "Silverlight" menu item to my menus, and give the user the familiar option of launching the "Microsoft Silverlight Configuration" dialog. This is the dialog lets users manage Updates, Webcams, Permissions, and Application Storage. So I need a way to programatically launch the dialog when the menu item is clicked. I can be done for Flash, and it would seem that Microsoft would want to encourage developers to support that option. Can it be done?

  • Need to work out database structure

    - by jim smith
    Hi, Just need a little kickstart with this. I have Mysql/PHP, and I have 5,000 products. I have 30 companies I need to store some data for those 30 companies for each product as follows: a) prices b) stock qty I also need to store data historically on a daily basis. So the table... It makes sense that the records will be the products because there's 5000, and if I put the companies as the columns, I can store the prices, but what about the stock quantities? I could create two columns for each compoany, one for prices, one for qty. Then make the tablename the date for that day...so theer would be a new table for every day with 5000 products in it? is this the correct way? Some idea on how I'll be retreiving data the top 5 lowest prices (and the company) by product for a certain date the price and stock changes in the past 7 days by product

  • Where to start on creating finger swipe navigation trough a list.

    - by Thomas Stock
    Lets say I want to make a control to select any integer number by dragging on a "bar" with numbers: (156 is selected) Mousedown on "159" and dragging towards the left and then doing mouseup changes the control to this: (160 is selected) I've been experimenting for the past 3 hours but I'm inexperienced in Silverlight so I'm having problems getting started. My current guess is I should seperate this into 2 steps: Step 1: Build this control without swiping behavior. Just 2 buttons to go up a number or go down a number Step 2: Replace the buttons by handling mouse events. With my limited knowledge I think I would manage building a crappy control that does this, with very messy xaml and c# and lots of headaches when trying to apply styling and fancy state transitions, but I was hoping some xaml wizards could get me started with the basic approach? Edit: This is an implementation of what I'm trying to achieve in Silverlight: Iphone's datepicker:

  • Auto-Complete Suggestions in Source Code Editor

    - by Jim
    Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

  • NSWindowController and isWindowLoaded

    - by Jim
    Hi, I have an NSWindowController and I initialize it like this; + (MyWindowController *) sharedController { static MyWindowController *singleton = nil; if (!singleton) singleton = [[self alloc] initWithWindowNibName: @"myWindow"]; return singleton; } and I show windows like this; [[MyWindowController sharedController] showWindow: nil]; Now the problem is that I need information from some controls on that window. But I do not want to load the window if it's not yet loaded because then I can just go with the defaults. Should I use @property to access the singleton? or what is recommended here? (If @property, then please give me the readonly, nonatomic attributes too.)

  • NSThread running a class

    - by Thomas Joulin
    Hi, Every the example I find on the internet (including Apple doc) sets the target to self like this : [NSThread detachNewThreadSelector:@selector(threadedTask) toTarget:self withObject:nil]; Since i would like to do a more complex task in background (involving multiple methods), I thought of creating a class Task called like this : Task *task = [[Task alloc] init]; [NSThread detachNewThreadSelector:@selector(main) toTarget:task withObject:nil]; but I wonder, how will be handled the instance variables of my class Task ? in my method main can I safely call methods of my class Task using [self myMethod] and modifying members variables assuming I'm the only thread accessing it ? This way of handling threads seems weird to me, sorry if my question is stupid ^^ Thanks in advance

  • Recommended NetBeans UML plugins

    It appears that the NetBeans UML plugin has been discontinued, as per a discussion on the NetBeans forums. This was a great, free tool with nice model-code and code-model generation. There are a number of other UML NetBeans plugins out there. However, I've never used any of them. Any suggestions?

  • Creating BlackBerry method stubs using wscompile on WSDL from ColdFusion

    - by Jim B
    I have been working on a BlackBerry application that consumes web services from ColdFusion 7. The Java ME SDK and the Java Wireless Toolkit both require that the generated WSDL be of the document/literal type. Fortunately, I have input on the web service development so I tried setting 'style="document"' in the cfcomponent tag. This generated a document/literal style WSDL but now wscompile generates the following errors in several places: Found unknown simple type: javax.xml.soap.SOAPElement Found unknown simple type: java.util.Calendar Any ideas why this is happening? The WSDL does get parsed correctly by the JWSDP tool but the stubs use namespaces that are not available in the J2ME platform. I would have thought ColdFusion WSDL would work more easily with other products in the Java family.
