Need help in support multiple resolution screen on android

- by michael

Hi, In my android application, I would like to support multiple screens. So I have my layout xml files in res/layout (the layout are the same across different screen resolution). And I place my high-resolution asserts in res/drawable-hdpi In my layout xml, I have <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/table" android:background="@drawable/bkg"> And I have put bkg.png in res/drawable-hdpi And I have started my emulator with WVGA-800 as avd. But my application crashes: E/AndroidRuntime( 347): Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f020023 a=-1 r=0x7f020023} E/AndroidRuntime( 347): at android.content.res.Resources.loadDrawable(Resources.java:1677) E/AndroidRuntime( 347): at android.content.res.TypedArray.getDrawable(TypedArray.java:548) E/AndroidRuntime( 347): at android.view.View.<init>(View.java:1850) E/AndroidRuntime( 347): at android.view.View.<init>(View.java:1799) E/AndroidRuntime( 347): at android.view.ViewGroup.<init>(ViewGroup.java:284) E/AndroidRuntime( 347): at android.widget.LinearLayout.<init>(LinearLayout.java:92) E/AndroidRuntime( 347): ... 42 more Does anyone know how to fix my problem? Thank you.

Sortable clone helper not working

- by Jeremy Seekamp

Maybe I don't understand how clone works with sortable, but here is what I would like to do. When sorting an item I would like a clone of the item I am dragging remain until I stop drop the item in its new position. Here's the code: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/jquery-ui.min.js"></script> <style type="text/css"> .sort { width: 150px; } .ui-state-highlight { background-color: #000; height:2px; } </style> </head> <body> <div> <ul class="sort"> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> <li>Item 4</li> </ul> </div> <script type="text/javascript"> $(function() { $('.sort').sortable({ helper: 'clone', placeholder: 'ui-state-highlight', opacity: '.5' }) }) </script> </body> </html> Thanks in advance for the help!

How to pull one commit at a time from a remote git repository?

- by Norman Ramsey

I'm trying to set up a darcs mirror of a git repository. I have something that works OK, but there's a significant problem: if I push a whole bunch of commits to the git repo, those commits get merged into a single darcs patchset. I really want to make sure each git commit gets set up as a single darcs patchset. I bet this is possible by doing some kind of git fetch followed by interrogation of the local copy of the remote branch, but my git fu is not up to the job. Here's the (ksh) code I'm using now, more or less: git pull -v # pulls all the commits from remote --- bad! # gets information about only the last commit pulled -- bad! author="$(git log HEAD^..HEAD --pretty=format:"%an <%ae>")" logfile=$(mktemp) git log HEAD^..HEAD --pretty=format:"%s%n%b%n" > $logfile # add all new files to darcs and record a patchset. this part is OK darcs add -q --umask=0002 -r . darcs record -a -A "$author" --logfile="$logfile" darcs push -a rm -f $logfile My idea is Try git fetch to get local copy of the remote branch (not sure exactly what arguments are needed) Somehow interrogate the local copy to get a hash for every commit since the last mirroring operation (I have no idea how to do this) Loop through all the hashes, pulling just that commit and recording the associated patchset (I'm pretty sure I know how to do this if I get my hands on the hash) I'd welcome either help fleshing out the scenario above or suggestions about something else I should try. Ideas?

Oracle T4CPreparedStatement memory leaks?

- by Jay

A little background on the application that I am gonna talk about in the next few lines: XYZ is a data masking workbench eclipse RCP application: You give it a source table column, and a target table column, it would apply a trasformation (encryption/shuffling/etc) and copy the row data from source table to target table. Now, when I mask n tables at a time, n threads are launched by this app. Here is the issue: I have run into a production issue on first roll out of the above said app. Unfortunately, I don't have any logs to get to the root. However, I tried to run this app in test region and do a stress test. When I collected .hprof files and ran 'em through an analyzer (yourKit), I noticed that objects of oracle.jdbc.driver.T4CPreparedStatement was retaining heap. The analysis also tells me that one of my classes is holding a reference to this preparedstatement object and thereby, n threads have n such objects. T4CPreparedStatement seemed to have character arrays: lastBoundChars and bindChars each of size char[300000]. So, I researched a bit (google!), obtained ojdbc6.jar and tried decompiling T4CPreparedStatement. I see that T4CPreparedStatement extends OraclePreparedStatement, which dynamically manages array size of lastBoundChars and bindChars. So, my questions here are: Have you ever run into an issue like this? Do you know the significance of lastBoundChars / bindChars? I am new to profiling, so do you think I am not doing it correct? (I also ran the hprofs through MAT - and this was the main identified issue - so, I don't really think I could be wrong?) I have found something similar on the web here: http://forums.oracle.com/forums/thread.jspa?messageID=2860681 Appreciate your suggestions / advice.

What is the fastest, most efficient way to get up to speed on a new technology?

- by SLC

My current job involves working with a huge number of technologies, most of which are very niche and unheard of. In some cases I have to write something about the technology, or with the technology, such as some lessons, examples, or tutorials, on behalf of the developer of that technology or someone that is backing it. When I get told to learn about a new technology, my first port of call is to check our internal library, and then look on amazon for a book on the subject. Failing that, or if the project is too small to warrant a purchase, I hit up google and youtube. However the results of randomly googling what I want to learn are hit and miss. Some days, I can find everything I want to know in a series of lessons or videos, and it's no problem. Other times, I can find almost nothing, and I really have to piece together things from sites. The result is that there are various resources out there, videos, interactive lessons, tutorials, books etc. but when I need to learn something fast, I often don't know the best way to go about it. It's not about fun, because I don't always have the luxury of working my way through a 600 page textbook named "A Complete Guide To Technology X", I have to deliver results quickly. One of the examples I'd like to use is ASP.NET MVC 2 which is something I have been told to learn. I grabbed a book on MVC 1 to refresh my knowledge, but googling it does't produce much useful information. I've seen a ton of ScottGu's tutorials on it, but they are mostly feature presentations, and some date back almost a year. The same applies to channel 9 and there are no books out yet on amazon. My question therefore has two parts, the first asks, "Where are the best places to look to get the information needed to learn a new technology?" and the second asks "What is the most efficient way to use such resources to learn a new technology?"

How to dispatch a new property value in an object to the same property of two other objects

- by WPFadvocate

In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects. Edited: here is my tentative code for multibinding, with the false hope that it would work without additional code: // create the multibinding MultiBinding mb = new MultiBinding() { Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }; // create individual bindings to associate object_2 and object_3 to object_1 Binding b2 = new Binding() { Source = object_2, Path = new PropertyPath("X") }; Binding b3 = new Binding() { Source = object_3, Path = new PropertyPath("X") }; // add individual bindings to multibinding mb.Bindings.Add(b2); mb.Bindings.Add(b3); // bind object_2 and _3 to object_1 BindingOperations.SetBinding(object_1, TypeObject_1.XProperty, mb); But actually, there is a runtime error, saying the binding set by the last instruction is lacking a converter. But again I don't know how to write this converter (there is nothing to convert (as this is the case in the related MS sample of code linking 3 rgb properties to a color property), only to forward the value of the property changed to the two other properties). I understand I could solve the problem by creating an X_Changed event in the 3 types and then have each object registering to the two other objects event. I don't like this "manual" way and would prefer to bind the 3 properties together.

Determine whether a canvas has been inserted into each page

- by Hadi Teo

Hi, Currently i have a code which will print OMR Mark on each pages. Basically i insert a canvas into each page and subsequently an OMR Mark Line Series are inserted into the canvas. Recently i found an issue that somehow one of the canvas is placed out of a page and it appears at the previous page instead of the current page. Below is the code snippet in how i inserted canvas as well as OMR Marks into each page: ' Start Code Snippet Sub GenerateOMR() Dim ShpCanvas As Shape Dim MaxPages As Integer Dim PNo As Integer ClearOMR MaxPages = Selection.Information(wdNumberOfPagesInDocument) For PNo = 1 To MaxPages Selection.GoTo What:=wdGoToPage, Which:=wdGoToFirst, Count:=PNo, Name:="" Select Case PNo Case 1 Set ShpCanvas = ActiveDocument.Shapes.AddCanvas(0, 0.5, 600, 300) Case Else Set ShpCanvas = ActiveDocument.Shapes.AddCanvas(0, 0, 600, 300) End Select ' Add a canvas on each page With ShpCanvas .Name = "OMR_Canvas_" & CStr(PNo) .RelativeHorizontalPosition = wdRelativeHorizontalPositionPage .RelativeVerticalPosition = wdRelativeVerticalPositionPage End With ' Insert a white background rectange and remove the rectangle border line With ShpCanvas.CanvasItems.AddShape(msoShapeRectangle, 536, 0, 64, 300) .Name = "OMR_WhiteBackground_" & CStr(PNo) .Fill.ForeColor.RGB = RGB(255, 255, 255) .Line.ForeColor.RGB = RGB(255, 255, 255) End With PrintOMRPage ShpCanvas, PNo Next PNo End Sub ' End Code Snippet There is a custom method called PrintOMRPage method which is not relevant here. My question now, how do i know whether a canvas has been inserted into a page ? Basically i will loop in all the pages and check whether a canvas has been inserted into that page. Apparently i cannot find the correct way. I have tried to check using ActiveDocument.Shapes(1).Top and validate whether the Top position is a negative value. But apparently the Top position is always measured from the top of each page. Thanks for the help. hadi teo

VLC desktop streaming

- by StackedCrooked

Edit I stopped using VLC and switched to GMax FLV Encoder. It does a much better job IMO. Original post I am sending my desktop (screen) as an H264 video stream to another machine that saves it to a file using the follwoing command lines: Sender of the stream: vlc -I dummy --sout='#transcode{vcodec=h264,vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' Receiver of the stream: vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}' --ipv4 This works, but there are a few issues: The file is not playable with most players. VLC is able to playback the file but with some weirdness: = it takes about 10 seconds before the playback actually begins. = seeking doesn't work. Can someone point me in the right direction on how to fix these issues? EDIT: I made a little progress. The initial delay in playback is because the player is waiting for a keyframe. By forcing the sender of the stream to create a new key-frame every 4 seconds I could decrease the delay: :screen-fps=10 --sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' The seeking problem is not solved however, but I understand it a little better. The RTP stream is saved as a file in its original streaming format, which is normally not playable as a regular video file. VLC manages to play this file, but most other players don't. So I need to convert it to a regular video file. I am currently investigating whether I can do this with ffmpeg if I provide it with an SDP file for the recorded stream. All help is welcome!

Debugging strategy to find the cause of bad_alloc

- by SalamiArmi

I have a fairly serious bug in my program - occasional calls to new() throw a bad_alloc. From the documentation I can find on bad_alloc, it seems to be thrown for these reasons: When the computer runs out of memory (which definitely isn't happening, I have 4GB of RAM, program throws bad_alloc when using less than 5MB (checked in taskmanager) with nothing serious running in the background). If the memory becomes too fragmented to allocate new blocks (which, again, is unlikely - the largest sized block I ever allocate would be about 1KB, and that doesn't get done more than 100 times before the crash occurs). Based on these descriptions, I don't really have anywhere in which a bad_alloc could be thrown. However, the application I am running runs more than one thread, which could possibly be contributing to the problem. By testing all of the objects on a single thread, everything seems to be working smoothly. The only other thing that I can think of that is going on here could be some kind of race-condition caused by calling new() in more than one place at the same time, but I've tried adding mutexes to prevent that behaviour to no effect. Because the program is several hundred lines and I have no idea where the problem actually lies, I'm not sure of what, if any, code snippets to post. Instead, I was wondering if there were any tools that will help me test for this kind of thing, or if there are any general strategies that can help me with this problem. I'm using Microsoft Visual Studio 2008, with Poco for threading.

OpenGL - drawing 2D polygons shapes with texture

- by plonkplonk

I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

PostgreSQL - Why are some queries on large datasets so incredibly slow

- by Brad Mathews

Hello, I have two types of queries I run often on two large datasets. They run much slower than I would expect them to. The first type is a sequential scan updating all records: Update rcra_sites Set street = regexp_replace(street,'/','','i') rcra_sites has 700,000 records. It takes 22 minutes from pgAdmin! I wrote a vb.net function that loops through each record and sends an update query for each record (yes, 700,000 update queries!) and it runs in less than half the time. Hmmm.... The second type is a simple update with a relation and then a sequential scan: Update rcra_sites as sites Set violations='No' From narcra_monitoring as v Where sites.agencyid=v.agencyid and v.found_violation_flag='N' narcra_monitoring has 1,700,000 records. This takes 8 minutes. The query planner refuses to use my indexes. The query runs much faster if I start with a set enable_seqscan = false;. I would prefer if the query planner would do its job. I have appropriate indexes, I have vacuumed and analyzed. I optimized my shared_buffers and effective_cache_size best I know to use more memory since I have 4GB. My hardware is pretty darn good. I am running v8.4 on Windows 7. Is PostgreSQL just this slow? Or am I still missing something? Thanks! Brad

Inflated ImageView to put in GalleryView isn't the right size

- by Richard

I am trying to inflate an ImageView that scales a Drawable that I can display in a GalleryView. My code to inflate the view seems to work fine, except that the attributes of the ImageView are not applied. Specifically, the inflated ImageView does not have the width/height that I set for it via the android:layout params in XML. Can someone show me what I'm doing wrong? I want to set the width/height of the image in dp, so that it is the correct size across multiple screen dpis and support Android 1.5+. As a result I cannot use something like: i.setLayoutParams(new Gallery.LayoutParams(150, 116) My layout definition is: <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="150dp" android:layout_height="116dp" android:background="@drawable/gallery_item_background" android:scaleType="fitXY" /> </ImageView> And the snippet I am using to inflate the ImageView is: public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); ImageView i = (ImageView) inflater.inflate(R.layout.gallery_item, null); i.setImageResource(mImageIds.get(position)); i.setScaleType(ImageView.ScaleType.FIT_XY); return i; }

Subclassing an NSTextField

- by Hooligancat

Given all the complex things I seem to cover every day, this appears to be a "what the heck am I doing wrong that seems to simple?" scenario! I would like to subclass an NSTextField to change the background color and text color. For simplicity sake (and to help anyone who hasn't ever subclassed anything before), here is the example of my (simplified) subclass MyNSTextFieldSubclass... Step 1: Create the subclass file: First the header file @interface MyTextFieldSubclass : NSTextField { } @end And the method file @implementation MyTextFieldSubclass -(NSColor *)backgroundColor { return [NSColor redColor]; } -(NSColor *)textColor { return [NSColor yellowColor]; } @end Step 2: Drag an NSTextField to a window in Interface Builder, select the Identity tab in the inspector and select the class MyTextFieldSubclass Step 3: Save the IB file, build and run the application Problem When I run the build, the text field does not reflect the color subclassing. However, I know the subclass is being called because if I add the following method, it gets called on text changes. -(void)textDidChange:(NSNotification *)notification { NSLog(@"My text changed"); } So why does the color change not occur on the text fields? I know that I can set the color in IB, but for anyone who has dealt with a lot of UI elements that all need the same styling, subclassing makes life way, way easier. Ironically, I have never had to subclass an NSTextField before and this one has me stumped. As usual, any and all help very much appreciated. I'm sure it will turn out to be a "Doh!" moment - just cant see the wood for the trees right now (plus I'm exhausted from watching too much World Cup Football early in the morning which never helps).

I am trying to make a simple widget that will play a movie from the sdcard when clicked on. This seems simple enough, and by following tutorials I've come up with the following code, but it seems the onclick is never setup. Manifest: <receiver android:name="WidgetProvider" android:label="DVD Cover"> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/appwidget_info_2x4"/> </receiver> Layout (widget.xml): <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/holder" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ff777777" > <ImageView android:id="@+id/cover" android:layout_width="wrap_content" android:layout_height="fill_parent" android:textColor="#000000" /> </LinearLayout> appwidget.xml: <?xml version="1.0" encoding="utf-8"?> <appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" android:minWidth="200dip" android:minHeight="300dip" android:updatePeriodMillis="180000" android:initialLayout="@layout/widget" > </appwidget-provider> WidgetProvider.java: public class WidgetProvider extends AppWidgetProvider { public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { String movieurl = Environment.getExternalStorageDirectory().getPath() + "/Movie.mp4"; Intent notificationIntent = new Intent(Intent.ACTION_VIEW); notificationIntent.setDataAndType(Uri.parse(movieurl), "video/*"); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,0); // Get the layout for the App Widget and attach an on-click listener // to the button RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); views.setOnClickPendingIntent(R.id.holder, contentIntent); // Tell the AppWidgetManager to perform an update on the current app widget appWidgetManager.updateAppWidget(appWidgetIds, views); } } Any help would be greatly appreciated.

Regex problem in Java in code sample

- by JaneNY

I have job with regex in my expressions: example !(FA1_A.i & FA1_M.i) I have operators ! ( ) & | operands have names [a-zA-Z_]*.[a-zA-Z_] I wrote in Java to split on tokens, but it doesn't split on operators and operands If should be !, (, FA1_A.i, &, FA1_m.i, ) . Can anybody tell me what is wrong ? String stringOpÐµrator = "([!|&()])"; String stringOperand = "(([a-zA-Z_]*)\\.([a-zA-Z_]*))"; String reg=stringOpÐµrator+"|"+stringOperand; Pattern pattern = Pattern.compile(reg); Matcher m = pattern.matcher(expression); // System.out.println("func: " + function + " item: " + item); while (m.find()) { int a=m.start(); int b=m.end(); String test=expression.substring(m.start(), m.end()); String g=test; tokens.add(new Token(expression.substring(m.start() , m.end()))); //m = pattern.matcher(expression); }

GenerateDSYMFile warning: unable to open object file

- by regulus6633

The background: I have a project that I last built on 10.5 on a PPC computer using xcode v3.1. It builds against the 10.4 SDK. I now have a MacBook with 10.6 on it and Xcode v3.2.1. I installed the 10.4 SDK with xcode. So now I want to build the project on an intel chip on 10.6. I first get a build error because I have the wrong version of gcc setup so I change the build settings to use gcc 4.0. The problem: Now when I build the project I get the following warning: GenerateDSYMFile "build/Release/What's Keeping Me?.app.dSYM" "build/Release/What's Keeping Me?.app/Contents/MacOS/What's Keeping Me?" cd "/Users/hmcshane/Development/ Cocoa Projects/What's Keeping Me?" /Developer/usr/bin/dsymutil "/Users/hmcshane/Development/ Cocoa Projects/What's Keeping Me?/build/Release/What's Keeping Me?.app/Contents/MacOS/What's Keeping Me?" -o "/Users/hmcshane/Development/ Cocoa Projects/What's Keeping Me?/build/Release/What's Keeping Me?.app.dSYM" warning: (i386) /Users/hmcshane/Downloads/Csu-71/crt.dynamic_no_pic.o unable to open object file warning: (ppc7400) /Users/hmcshane/Downloads/Csu-71/crt.dynamic_no_pic.o unable to open object file Any idea what this is? And why is the path for the problem files rooted in my downloads folder? The project certainly doesn't reside there.

Which Javascript framework (jQuery vs Dojo vs ... )?

- by cletus

There are a few Javascript frameworks/toolets out there, such as: jQuery; Dojo; Prototype; YUI; MooTools; ExtJS; SmartClient; and others I'm sure. It certainly seems that jQuery is ascendant in terms of mindshare at the moment. For example, Microsoft (ASP.NET MVC) and Nokia will use it. I also found this this performance comparison of Dojo, jQuery, MooTools and Prototype (Edit: Updated Comparison), which looks highly favourable to Dojo and jQuery. Now my previous experience with Javascript has been the old school HTML + Javascript most of us have done and RIA frameworks like Google Web Toolkit ("GWT") and Ext-GWT, which were a fairly low-stress entry into the Ajax world for someone from a Java background, such as myself. But, after all this, I find myself leaning towards the more PHP + Ajax type solution, which just seems that much more lightweight. So I've been looking into jQuery and I really like it's use of commands, the use of fluent interfaces and method chaining, it's cross-browser CSS selector superset, the fact that it's lightweight and extensible, the brevity of the syntax, unobtrusive Javascript and the plug-in framework. Now obviously many of these aren't unique to jQuery but on the basis that some things are greater than their sum of parts, it just seems that it all fits together and works well. So jQuery seems to have a lot going for it and it looks to the frontrunner for what I choose to concentrate on. Is there anything else I should be aware of or any particular reasons not to choose it or to choose something else? EDIT: Just wanted to add this trend comparison of Javascript frameworks.

What are the specific names for these OLE controls?

- by Kris

I have been working on making a block of code that would enable me to input values into a worksheet, as well as an MSgraph object. I have succeeded in this, but this has just presented me with a new set of problems: What are the control names for changing the visible size as well as the focus of a worksheet? What are the control names for changing/making background colours and borders? How do I create and define new worksheets and MSGraph objects inside the document? My example code so far: Option Explicit Dim objWord 'Word application object Dim objIShape 'Inline shapes object Dim objOLE 'OLE object Set objWord=CreateObject("Word.Application") objWord.Application.Documents.Open("C:\birdy.doc") objWord.Visible=True Set objIShape = objWord.ActiveDocument.InlineShapes Function count_filled_spaces(intOLENo, strRange) 'Activates the the inline shape by number(intOLENo) and defines it as the OLE object objIShape(intOLENo).OLEFormat.Activate Set objOLE = objIShape(intOLENo).OLEFormat.Object 'Detects the ClassType of the inline shape and uses a class specific counter to count which datafields have data Dim strClass, i, p, intSheetno intSheetno = 1 strClass = objIShape(intOLENo).OLEFormat.ClassType i = 0 If Left(strClass, 8) = "MSGraph." then For Each p In objOLE.Application.DataSheet.Range(strRange) If p <> "" Then i = i+1 End If Next ElseIf Left(strClass, 6) = "Excel." then For Each p In objOLE.Worksheets(intSheetno).Range(strRange) If p <> "" Then i = i+1 End If Next objOLE.Worksheets(intSheetno).Range("B" & i+1) = objOLE.Worksheets(intSheetno).Range("B" & i) End if count_filled_spaces = i End Function Dim strRange strRange = InputBox("Lol", "do eeet", "B1:B10") wscript.echo count_filled_spaces(2, strRange) 'objWord.Application.Documents.Save 'objWord.Application.Documents.Close 'objWord.Application.Quit WScript.Quit(0)

Hi all, How we can define JS function on inside ? I tried to load file javascript on the end tag , but I still can't call the function from javascript file. Here the FBML tag <fb:serverfbml> <script type="text/fbml"> <fb:fbml> <a href="#" id="this" onclick="do_colors(this); return false">Hello World!</a> <script src="http://absolute.path.to/your/javascript/file.js"></script> </fb:fbml> </script> </fb:serverfbml> And here the javacript function on file.js function random_int(lo, hi) { return Math.floor((Math.random() * (hi - lo)) + lo) } function do_colors(obj) { var r = random_int(0, 255), b = random_int(0, 255), g = random_int(0, 255); obj.setStyle({background: 'rgb('+[r, g, b].join(',')+')', color: 'rgb('+[r<128?r+128:r-128, g<128?g+128:g-128, b<128?b+128:b-128].join(',')+')'}); } I use rails and facebooker to develop the application Any idea or suggestion for define javascript functions?

Where to put external archives to configure running in Eclipse?

- by Buggieboy

As a Java/Eclipse noob coming from a Visual Studio .NET background, I'm trying to understand how to set up my run/debug environment in the Eclipse IDE so I can start stepping through code. I have built my application with separate src and bin hierarchies for each library project, and each project has its own jar. For example, in a Windows environment, I have something like: c:\myapp\myapp_main\src\com\mycorp\myapp\main ...and a parallel "bin" tree like this: c:\myapp\myapp_main\bin\com\mycorp\myapp\main Other supporting projects are, similarly: **c:\myapp\myapp_util\src\com\mycorp\myapp\uti**l (and a parallel "bin" tree.) ... etc. So, I end up with, e.g., myapp_util.jar in the ...\myapp_util\bin... path and then add that as an external archive to my myapp_main project. I also use utilities like gluegen-rt.jar, which I add ad external dependencies to the projects requiring them. I have been able to run outside of the Eclipse environment, by copying all my project jars, gluegen-rt DLL, etc., into a "lib" subfolder of some directory and executing something like: java -Djava.library.path=lib -DfullScreen=false -cp lib/gluegen-rt.jar;lib/myapp_main.jar;lib/myapp_util.jar; com.mycorp.myapp.Main When I first pressed F11 to debug, however, I got a message about something like /com/sun/../glugen... not being found by the class loader. So, to debug, or even just run, in Ecplipse, I tried setting up my VM arguments in the Galileo Debug - (Run/Debug) Configurations to be the command line above, beginning at "-Djava.libary.path...". I've put a lib subdirectory - just like the above with all jars and the native gluegen DLL - in various places, such as beneath the folder that my main jar is built in and as a subfolder of my Ecplipse starting workspace folder, but now Eclipse can't find the main class: java.lang.NoClassDefFoundError: com.mycorp.myapp.Main Although the Classpath says that it is using the "default classpath", whatever that is. Bottom line, how do I assemble the constituent files of a multi-project application so that I can run or debug in Ecplipse?

Interactive Web Collaboration Platform

- by user1477586

I am currently unsatisfied with most, if not all, web-based collaboration tools I've ever used. Examples of what I'm considering a "web-based collaboration tool" are TWiki, WebEx, etc. What I have in mind of developing is to develop my own. The target "market" is for software/hardware developers who will likely be working on separate projects linked by a common goal. Example: You work at a company who is designing a brand new printer. So, one man is working on the ink cartridge, another on the paper feed, one on the circuitry of the printer and one more is working on the drivers. What I would like to make (unless it already exists) is a website that, upon loading, presents the user with a web that has each project within it's own bubble, graphically. These bubbles would all be linked to the central bubble of "[Company Name]". Upon selecting an individual bubble the browser would focus and zoom in on that project bubble and expand more information (in bullets or with more affiliated bubbles) about subprojects, progress, setbacks, etc. Then, at a terminal "node" (i.e. a bubble with no sub-bubbles) a selection would then load a page with information relevant to that node. That's a lot of monologue. In short, I want to know how I might approach this. My background is with algorithmic use of Python and C++. I've never done interactive web design like this; though, I have gone through the W3C tutorials on HTML4/5. I'm willing to learn a new language I'm just wondering which language/set of languages seem(s) most appropriate for this project. Thanks, world, for imparting your knowledge to me.

Application doesn't exit with 0 threads

- by Bryce Wagner

We have a WinForms desktop application, which is heavily multithreaded. 3 threads run with Application.Run and a bunch of other background worker threads. Getting all the threads to shut down properly was kind of tricky, but I thought I finally got it right. But when we actually deployed the application, users started experiencing the application not exiting. There's a System.Threading.Mutex to prevent them from running the app multiple times, so they have to go into task manager and kill the old one before they can run it again. Every thread gets a Thread.Join before the main thread exits, and I added logging to each thread I spawn. According to the log, every single thread that starts also exits, and the main thread also exits. Even stranger, running SysInternals ProcessExplorer show all the threads disappear when the application exits. As in, there are 0 threads (managed or unmanaged), but the process is still running. I can't reproduce this on any developers computers or our test environment, and so far I've only seen it happen on Windows XP (not Vista or Windows 7 or any Windows Server). How can a process keep running with 0 threads?
