• Alternate cause of BadImageFormatException in .NET Assembly?

  - by Phillip Knauss

  I'm working on a .NET 3.5 console application in C# which uses a VC++ unmanaged DLL. It ran without a problem when I worked on it a few weeks ago, but I'm coming back to it today and am now getting a BadImageFormatException ("An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)). My development workstation is running 64bit Windows 7, and I do a fair amount of work with unmanaged code, so I immediately checked that the .NET assembly and the VC++ library both had x86 targets. They did. Just to be sure, I cleaned and rebuilt the VC++ library and the .NET assembly, to no avail. Neither system is doing anything particularly unusual. The VC++ library loads a binary data file and does some mathematical processing on its contents. The .NET assembly has the DllImports for the library and some code to wire it up. This all worked a few weeks ago. So now I'm left wondering if there's some other cause of BadImageFormatException that's less common than an x86/x64 conflict that I might be running into. Thanks.

• EDIT Control Showing Squares Instead Of Returns

  - by Nathan Campos

  I'm playing a little bit with PocketC by doing a simple text editor. But with this code to read and to display the contents of the file on the EDIT control: int filehandle; int file_len; string file_mode; initComponents() { createctrl("EDIT", "test", 2, 1, 0, 24, 70, 25, TEXTBOX); wndshow(TEXTBOX, SW_SHOW); guigetfocus(); } main() { filehandle = fileopen(OpenFileDlg("Plain Text Files (*.txt)|*.txt; All Files (*.*)|*.*"), 0, FILE_READWRITE); file_len = filegetlen(filehandle); if(filehandle == -1) { MessageBox("File Could Not Be Found!", "Error", 3, 1); } initComponents(); editset(TEXTBOX, fileread(filehandle, file_len)); } It's all ok, but my test file, now have returns: Hello, World! PocketC Test Of My Editor Then when I open this file on the editor, instead of returns, I just see two squares(that means that it's a unknown character for that control), but if I change the control to a STATIC, it does he returns ok, but I can't edit the text if I use a STATIC. Then I want to know what I need to do to do the returns instead of showing those squares.

• How do I process a nested list?

  - by ddbeck

  Suppose I have a bulleted list like this: * list item 1 * list item 2 (a parent) ** list item 3 (a child of list item 2) ** list item 4 (a child of list item 2 as well) *** list item 5 (a child of list item 4 and a grand-child of list item 2) * list item 6 I'd like to parse that into a nested list or some other data structure which makes the parent-child relationship between elements explicit (rather than depending on their contents and relative position). For example, here's a list of tuples containing an item and a list of its children (and so forth): [('list item 1',), ('list item 2', [('list item 3',), [('list item 4', [('list item 5'),]] ('list item 6',)] I've attempted to do this with plain Python and some experimentation with Pyparsing, but I'm not making progress. I'm left with two major questions: What's the strategy I need to employ to make this work? I know recursion is part of the solution, but I'm having a hard time making the connection between this and, say, a Fibonacci sequence. I'm certain I'm not the first person to have done this, but I don't know the terminology of the problem to make fruitful searches for more information on this topic. What problems are related to this so that I can learn more about solving these kinds of problems in general?

• File-level filesystem change notification in Mac OS X

  - by Paul J. Lucas

  I want my code to be notified when any file under (either directly or indirectly) a given directory is modified. By "modified", I mead I want my code to be notified whenever a file's contents are altered, it's renamed, or it's deleted; or if a new file is added. For my application, there can be thousands of files. I looked as FSEvents, but its Technology Overview says, in part: The important point to take away is that the granularity of notifications is at a directory level. It tells you only that something in the directory has changed, but does not tell you what changed. It also says: The file system events API is also not designed for finding out when a particular file changes. For such purposes, the kqueues mechanism is more appropriate. However, in order to use kqueue on a given file, one has to open the file to obtain a file descriptor. It's impractical to manage thousands of file descriptors (and would probably exceed the maximum allowable number of open file descriptors anyway). Curiously, under Windows, I can use the ReadDirectoryChangesW() function and it does precisely what I want. So how can one do what I want under Mac OS X? Or, asked another way: how would one go about writing the equivalent of ReadDirectoryChangesW() for Mac OS X in user-space (and do so very efficiently)?

• How can I open VLC via browser with PHP (Mac OS X)

  - by Damiqib

  I'm trying to open VLC via browser and make it instantly play the given video file on Mac OS X. This runs on my local server and is only meant to run locally - therefore I already run apache (MAMP) with my username and with group "staff" (defined in httpd.conf). YES - I do know that VLC has http interface - however that is not what I need, so do not suggest that... My current system works without any problems when I run it via Terminal: php /var/www/Movies/index.php - This leads to VLC opening and video starts playing fullscreen like intented. Problems start when I run the same PHP-page with browser. Then the VLC-process starts, but there's no GUI for it, video file won't start playing and the VLC-process takes nearly 100% of CPU. Both; terminal and browser started VLC-processes run with the same user (mine) Both have "Parent process" bash VLC-process begun with Terminal has empty "Process group" (only process id-number) and browser started has "httpd" + (id-number) VLC-process started via browser makes 1000-times more "Mach System Calls" than it's Terminal-started counterpart. Could anyone give me any pointers on how to get this thing working? index.php # $j is a file path to the videofile and is defined before exec('/var/www/Movies/vlc.sh "' . $j . '" > /dev/null 2>&1 & echo $!;'); # If I do this in the given PHP-page it tells me that apache is running # with my username and with the group "staff" like it should be... exec('whoamI'); vlc.sh #!/bin/bash # Activate VLC in 5 seconds to make it the front-most window (sleep 5; open -a VLC) & # Open video file /Applications/VLC.app/Contents/MacOS/VLC --quiet --fullscreen "$1"

• I'v installed NetBeans 6.8 on my MacOS X MacBook and the logs say it cannot be run, any ideas?

  - by codezealot

  I've installed NetBeans 6.8 on my MacBook, and the installation results indicated success. However, every single time I attempt to run the application is shuts down. I monitored the process and noticed the following entries in the console that imply the application cannot be found? 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] /Applications/NetBeans/NetBeans 6.8.app/Contents/MacOS/netbeans: line 57: dirname: command not found 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] Cannot read cluster file: /../etc/netbeans.clusters 3/19/10 10:20:20 PM com.apple.launchd.peruser.501[77] ([0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168]) Exited with exit code: 1 I started researching how to set the default JDK for use by NetBeans, and found repeated use of the following command line entry; netbeans --jdkhome /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home -- from http://wiki.netbeans.org/JDKVersionAndMacOS When I attempt the command line above, I receive "netbeans command not found". So do I ... 1.) Need to create a command called "netbeans" that points to my install location for NetBeans 6.8? If so how do I do that? 2.) How do I get to the netbeans.conf file for NetBeans 6.8, does one even exist for it? It gets even more interesting, the above happens with Eclipse as well. Yippie.

• Maven String Replace of Text Web Resources

  - by Jaco van Niekerk

  I have a Maven web application with text files in src/main/webapp/textfilesdir As I understand it, during the package phase this textfilesdir directory will be copied into the target/project-1.0-SNAPSHOT directory, which is then zipped up into a target/project-1.0-SNAPSHOT.war Problem Now, I need to do a string replacement on the contents of the text files in target/project-1.0-SNAPSHOT/textfilesdir. This must then be done after the textfilesdir is copied into target/project-1.0-SNAPSHOT, but prior to the target/project-1.0-SNAPSHOT.war file being created. I believe this is all done during the package phase. How can a plugin (potentially maven-antrun-plugin), plug into the package phase to do this. The text files don't contain properties, like ${property-name} to filter on. String replacement is likely the only option. Options Modify the text files after the copy into target/project-1.0-SNAPSHOT directory, yet prior to the WAR creation. After packaging, extract the text files from WAR, modify them, and add them back into the WAR. I'm thinking there is another option here I'm missing. Thoughts anyone?

• Most efficient way to send images across processes

  - by Heinrich Ulbricht

  Goal Pass images generated by one process efficiently and at very high speed to another process. The two processes run on the same machine and on the same desktop. The operating system may be WinXP, Vista and Win7. Detailled description The first process is solely for controlling the communication with a device which produces the images. These images are about 500x300px in size and may be updated up to several hundred times per second. The second process needs these images to display them. The first process uses a third party API to paint the images from the device to a HDC. This HDC has to be provided by me. Note: There is already a connection open between the two processes. They are communicating via anonymous pipes and share memory mapped file views. Thoughts How would I achieve this goal with as little work as possible? And I mean both work for me and the computer. I am using Delphi, so maybe there is some component available for doing this? I think I could always paint to any image component's HDC, save the content to memory stream, copy the contents via the memory mapped file, unpack it on the other side and paint it there to the destination HDC. I also read about a IPicture interface which can be used to marshall images. What are your ideas? I appreciate every thought on this!

• AJAX CascadingDropDown ViewState Problem

• What is the best way to automatically transpose a LilyPond source file into multiple keys?

  - by Michael Steele

  problem I'm using LilyPond to typeset sheet music for a church choir to perform. Depending on who is available on any given week, songs will be played in various keys. We have an amazing pianist who can play anything we throw at her and the guitarists will typically pencil in alternate chords, but I want to make things easier by having beautifully typeset sheet music available in any key we want. So say we're going to sing our ABCs. First I'll take whatever source transcriptions available and enter it into a LilyPond script: melody = \relative c' { c c g g a a g2 f f e e d d c2 } I want the ability to transpose this automatically, so if I want the whole thing in 'G' I wrap the song in a \transpose call like so: melody = \transpose c g \relative c' { c c g g a a g2 f f e e d d c2 } What I really want is to substitute something for the 'g' and generate the output for melody multiple times. Simple LilyPond variables don't seem to work here, and so far I've been unsuccessful in defining a scheme function to do this. What I've resorted to for the moment is taking the above file, call it twinkle.ly and turning it into an M4 script called twinkle.ly.m4, the contents of which look like this: melody = \transpose c _key \relative c' { c c g g a a g2 f f e e d d c2 } I then compile the while thing by executing the following line: > m4 -D _key=g twinkle.ly.m4 > twinkle_g.ly && lilypond twinkle_g.ly I've written a Makefile to do this for me, defining rules for every song I have and every key I'm interested in. question There's got to be a better way of going about this. Given that Lilypond supports embedded scheme, I would prefer to not use a macro preprocessed on it. Has anybody else come up with a solution to this same problem?

• Customize a WCF RIA Services Endpoint

  Is it possible to customize the parameters of a WCF RIA Services endpoint? Specifically, I would like to create a custom binding for the endpoint and increase the maxReceivedMessageSize to allow sending the contents of a file that is a few megabytes in size.

• Scale transform in xaml (in a controltemplate) on a button to perform a "zoom"

• Detecting what changed in an HTML Textfield

  - by teehoo

  For a major school project I am implementing a real-time collaborative editor. For a little background, basically what this means is that two(or more) users can type into a document at the same time, and their changes are automatically propagated to one another (similar to Etherpad). Now my problem is as follows: I want to be able to detect what changes a user carried out onto an HTML textfield. They could: Insert a character Delete a character Paste a string of characters Cut a string of characters I want to be able to detect which of these changes happened and then notify other clients similar to "insert character 'c' at position 2" etc. Anyway I was hoping to get some advice on how I would go about implementing the detection of these changes? My first attempt was to consider the carot position before and after a change occurred, but this failed miserably. For my second attempt I was thinking about doing a diff on the entire contents of the textfields old and new value. Am I missing anything obvious with this solution? Is there something simpler?

• Keeping the UI responsive while parsing a very large logfile

  - by Carlos

  I'm writing an app that parses a very large logfile, so that the user can see the contents in a treeview format. I've used a BackGroundWorker to read the file, and as it parses each message, I use a BeginInvoke to get the GUI thread to add a node to my treeview. Unfortunately, there's two issues: The treeview is unresponsive to clicks or scrolls while the file is being parsed. I would like users to be able to examine (ie expand) nodes while the file is parsing, so that they don't have to wait for the whole file to finish parsing. The treeview flickers each time a new node is added. Here's the code inside the form: private void btnChangeDir_Click(object sender, EventArgs e) { OpenFileDialog browser = new OpenFileDialog(); if (browser.ShowDialog() == DialogResult.OK) { tbSearchDir.Text = browser.FileName; BackgroundWorker bgw = new BackgroundWorker(); bgw.DoWork += (ob, evArgs) => ParseFile(tbSearchDir.Text); bgw.RunWorkerAsync(); } } private void ParseFile(string inputfile) { FileStream logFileStream = new FileStream(inputfile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); StreamReader LogsFile = new StreamReader(logFileStream); while (!LogsFile.EndOfStream) { string Msgtxt = LogsFile.ReadLine(); Message msg = new Message(Msgtxt.Substring(26)); //Reads the text into a class with appropriate members AddTreeViewNode(msg); } } private void AddTreeViewNode(Message msg) { TreeNode newNode = new TreeNode(msg.SeqNum); BeginInvoke(new Action(() => { treeView1.BeginUpdate(); treeView1.Nodes.Add(newNode); treeView1.EndUpdate(); Refresh(); } )); } What needs to be changed?

• Can't start the portable version of NetBeans 6.9.1 IDE

  I downloaded the portable version of netbeans netbeans-6.9.1-201007282301-ml.zip from the netbeans site and changed the config file in etc/netbeans.conf as indicated on the netbeans site.

It also creates a .netbeans directory when i try to start it. I don't see any errors and it just doesn't do anything else observable. Does anybody know how to set up this version of netbeans? Thanks.

• How to terminate a particular Azure worker role instance

  - by Oliver Bock

  Background I am trying to work out the best structure for an Azure application. Each of my worker roles will spin up multiple long-running jobs. Over time I can transfer jobs from one instance to another by switching them to a readonly mode on the source instance, spinning them up on the target instance, and then spinning the original down on the source instance. If I have too many jobs then I can tell Azure to spin up extra role instance, and use them for new jobs. Conversely if my load drops (e.g. during the night) then I can consolidate outstanding jobs to a few machines and tell Azure to give me fewer instances. The trouble is that (as I understand it) Azure provides no mechanism to allow me to decide which instance to stop. Thus I cannot know which servers to consolidate onto, and some of my jobs will die when their instance stops, causing delays for users while I restart those jobs on surviving instances. Idea 1: I decide which instance to stop, and return from its Run(). I then tell Azure to reduce my instance count by one, and hope it concludes that the broken instance is a good candidate. Has anyone tried anything like this? Idea 2: I predefine a whole bunch of different worker roles, with identical contents. I can individually stop and start them by switching their instance count from zero to one, and back again. I think this idea would work, but I don't like it because it seems to go against the natural Azure way of doing things, and because it involves me in a lot of extra bookkeeping to manage the extra worker roles. Idea 3: Live with it. Any better ideas?

• Block element, horizontal center aligned and minimum width possible

  - by Nazgulled

  Hi, I'm trying to have this block element to be horizontally aligned in the middle but at the same time I would like the width to be the minimum possible for the contents inside. But I don't think it's possible or I'm not able to do it myself... a#button-link { background: url("images/button-link.png") no-repeat scroll center left; margin: 12px auto 0 auto; display: block; width: 125px; height: 32px; line-height: 32px; padding-left: 35px; font-weight: bold; } This is my current code... The idea behind this is that the text for that tag could be slightly bigger or smaller depending on the user language and how much characters the same sentence has for that specific user's language. There's no way I can control but I still would like to have this element horizontally aligned to center. Is this possible with CSS?

• documenting class properties

  - by intuited

  I'm writing a lightweight class whose properties are intended to be publicly accessible, and only sometimes overridden in specific instantiations. There's no provision in the Python language for creating docstrings for class properties, or any sort of properties, for that matter. What is the accepted way, should there be one, to document these properties? Currently I'm doing this sort of thing: class Albatross(object): """A bird with a flight speed exceeding that of an unladen swallow. Properties: """ flight_speed = 691 __doc__ += """ flight_speed (691) The maximum speed that such a bird can attain """ nesting_grounds = "Throatwarbler Man Grove" __doc__ += """ nesting_grounds ("Throatwarbler Man Grove") The locale where these birds congregate to reproduce. """ def __init__(**keyargs): """Initialize the Albatross from the keyword arguments.""" self.__dict__.update(keyargs) Although this style doesn't seem to be expressly forbidden in the docstring style guidelines, it's also not mentioned as an option. The advantage here is that it provides a way to document properties alongside their definitions, while still creating a presentable class docstring, and avoiding having to write comments that reiterate the information from the docstring. I'm still kind of annoyed that I have to actually write the properties twice; I'm considering using the string representations of the values in the docstring to at least avoid duplication of the default values. Is this a heinous breach of the ad hoc community conventions? Is it okay? Is there a better way? For example, it's possible to create a dictionary containing values and docstrings for the properties and then add the contents to the class __dict__ and docstring towards the end of the class declaration; this would alleviate the need to type the property names and values twice. I'm pretty new to python and still working out the details of coding style, so unrelated critiques are also welcome.

• Pushing to a UITable inside a UIView from a UITableview

  - by Michael Robinson

  I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

• Scripts to parse and download iTunes Connect and AppStore data

  - by bradhouse

  I'm looking for recommendations of a script or series of scripts that download and parse iTunes Connect sales data and AppStore comments, ratings and rankings data for a defined app. I'm also aware of solutions like: AppViz appsales-mobile iphone-stats Heartbeat.app I'm sure I'll find a few more with more searching. I can't help but feel there must be a really decent set of open source scripts out there to do this, given how many developers are now writing apps for the AppStore. Would be interested to hear any commercial offerings as well (although my personal preference is for open source, so I can at least see what it is doing with my iTunes Connect login credentials). To be clear, I'm really looking for something that hits all of the areas mentioned: App Store (per store) Comments Ratings Category/store rankings iTunes Connect The contents of the sales reports Analysis/graphs of the data is not necessary (but would be a nice to have I guess). I'm not really looking for something like AppSales Mobile above, I would like the raw data so I can do my own analysis and formatting. So far it looks like AppViz (listed above) is the best out there. Any suggestions on what is good/available or should I just go roll my own?
