• Downloading file with ASIHTTPRequest - iPhone app

  - by lostInTransit

  Hi I am using the ASIHTTPRequest source code to download a file from a remote location. Surprisingly, the download happens but nothing happens after that. I have put in a log statement in the handleBytesAvailable method and can see the entire file worth of data is downloaded in parts and added to the fileDownloadOutputStream variable. But once all the bytes have been downloaded, nothing happens. The delegate methods are not called (neither fail, nor success). Can someone please tell me what is happening? Or what is the correct way to download a file from a remote server using ASIHTTPRequest? Thanks.

• Special case when calling InvokeScript with the winforms WebBrowser control does not work

  - by wang-min

  I am trying to use InvokeScript method on the WebBrowser control to execute a script on the web page that has been loaded into my WebBrowser control. If I am calling just a simple javascript function, this works properly. However, the javascript function that I am trying to call is nested within a variable like this: var holder = { DoA: function() { .... }, DoB: function() { ..... } } Calling holder.DoA works fine when called from within the javascript, but the function is not called successfully when I try to call it from within my C# code like this: object obj1 = m_webBrowser.Document.InvokeScript("holder.DoA"); Any ideas?

• Trouble parsing NMEA data from Serial Port.

  - by rross

  I'm retrieving NMEA sentences from a serial GPS. Then string are coming across like I would expect. The problem is that when parsing a sentence like this: $GPRMC,040302.663,A,3939.7,N,10506.6,W,0.27,358.86,200804,,*1A I use a simple bit of code to make sure I have the right sentect: string[] Words = sBuffer.Split(','); foreach (string item in Words) { if (item == "$GPRMC") { return "Correct Sentence"; } else { return "Incorrect Sentence } } I added the return in that location for the example. I have printed the split results to a text box and have seen that $GPRMC is indeed coming across in the item variable at some point. If the string is coming across why won't the if statement catch? Is is the $? How can I trouble shoot this?

• Visual Studio Debugging Issue

  - by Aaron M

  Seeing an issue when debugging in Visual Studio. All of the values under watch, and in the hover over window show up incorrectly. the only values that show properly, are values that are local to the method I am currently stepping through. For example the watch value for 'this' when debugging shows the following under value 0x00000000ffac0388 { btnBack=0x00000000ffaccf20 btnReply=0x00000000ffacd200 btnForward=0x00000000ffacd420...} some other variables show this, even though the variable is there. error: 'this.foo' does not exist The machine recently had windows 7 64 installed, since then this problem has occured. Visual studio has been reinstalled on this machine, and we verified that the settings in visual studio were exactly the same as a different PC that is the same machine and config.

• jQTouch with PhoneGap on webOS

  - by Steve Nay

  I'm writing an application in PhoneGap that I want to run on iOS, Android, and webOS. jQTouch plays nice with everything on iOS and Android, but not webOS. Since the webOS Mojo framework is based on Prototype (which uses the $ variable), it's necessary to use jQuery in noConflict mode. I can handle that much. However, the problem is that I also want to use the jQTouch plugin. The jqtouch.js file uses $ throughout, causing JavaScript errors when that file is loaded. Is there a way to run the jQTouch plugin (or any plugin for that matter) in my PhoneGap application without interfering with Prototype?

• Can't find how to import as one object or how to merge

  - by Aaron

  I need write a script in blender that creates some birds which fly around some obstacles. The problem is that I need to import a pretty large Collada model (a building) which consists of multiple objects. The import works fine, but the the building is not seen as 1 object. I need to resize and move this building, but I can only get the last object in the building (which is a camera)... Does anyone know how to merge this building in 1 object, group, variable... so I can resize and move it correctly? Part of the code I used: bpy.ops.wm.collada_import(filepath="C:\\Users\\me\\building.dae") building= bpy.context.object building.scale = (100, 100, 100) building.name = "building"

• Using CSS Classes for indivdual effects - opinions?

  - by Cool Hand Luke UK

  Hey, Just trying to canvas some opinions here. I was wondering how people go about adding individual effects to html elements. Take this example: you have three types of h1 titles all the same size but some are black some are gold and some are white. Some have a text-shadow etc. Would you create separate CSS classes and add them do the h1 tag or would you create a new single class for each different h1 title type (with grouped CSS elements)? With singular class for each effect you can build up combos of classes in html class="gold shadow" but also how would you name them. For example its bad practice to give classes and id names associated to colours, because it doesn't define what it does well. However is this ok with textual CSS classes? Just wondering what others do, I know there are no hard and fast rules. Cheers.

• C# can I lock a method parameter?

  - by 5YrsLaterDBA

  We have a class variable ArrayList binaryScanData in a class. In all methods having access to it, we put lock(binaryScanData) on it because it is shared. Now we want to move one of those methods out to another util class to make it a static method. We will pass that binaryScanData into the method like this: public static void convertAndSaveRawData(ref MemoryStream output, ref ArrayList binaryScanData) Our questions are followed: how can we sychoronize that binaryScanData? can we do the same as it is originally? ref is necessary? It will only be read in that convertAndSaveRawData method.

• jQuery Autocomplete: how to refresh list?

  - by cinematic

  I have a form with a variable number of autocomplete fields that use the same select list. These fields are added and removed as needed. Whenever a parameter on the page is changed, I (try to) update the list for all the fields by first calling unbind() then autocomplete() with a new parameter added to the url. $('input.foo').unbind().autocomplete(url?new_param=bar); The problem is that unbind() does not seem to be unbinding. When I type in the input field, it fires off the entire history of autocomplete events. I also tried flushCache to no avail. How do I clear out the old events? Thanks.

• jQuery.each for lists and non-lists

  - by Brian M. Hunt

  I've a jQuery.each(data, foo), where data is either a string or a list of strings. I'd like to know if there's an existing utility function to convert the string to a list, or otherwise perform foo on just the string. So instead of the easy route: if (!$.isArray(data)) { foo(0, data); // can't rely on `this` variable } else { $.each(data,foo); } I was just wondering if there was already a builtin function of jQuery or Javascript that would convert data to a list automatically, like this: function convert_to_list(data) { return $.isArray(data) ? data : [data]; } $.each(convert_to_list(data), foo); Just curious! Thanks for reading. Brian

• NSArrays in NSArrays. A pointer problem?

  - by RyJ

  I believe my problem involves pointers, a concept I often struggle with, but here's what I'm trying to do. I have six NSArrays. I want an additional NSArray comprised of these six arrays, so: self.arr1 = [NSArray array]; self.arr2 = [NSArray array]; self.arr3 = [NSArray array]; self.arr4 = [NSArray array]; self.arr5 = [NSArray array]; self.arr6 = [NSArray array]; NSArray *containerArray = [[NSArray alloc] initWithObjects:self.arr1, ... etc, nil]; Whenever I update one of the first 6 NSArrays, I want the object updated in containerArray. (I know I'm using an NSArray and not an NSMutableArray, when I update the arrays I create a new one and assign it to the instance variable). Currently, any manipulation of arr1 is not reflected in [containerArray objectAtIndex:0].

• Ruby IRB - Requires and Scope

  - by tyndall

  Trying to understand this problem I'm running into. I create file welcome.rb. The contents of this file: welcome_message = "hi there" I then launch an irb session. And type require 'welcome'. That works fine. Then I type: puts welcome_message I get the error message undefined local variable or method `welcome_message' for main:Object What is the best way to bring in predefined variables and have initialization work done when you require something into your irb session. Global variables didn't seem like the right path.

• How to add an Interbase connection pool to glassfish?

  - by kgrad

  Hi, I am attempting to add an Interbase connection pool to GlassFish v3 to use EJB 3.1 in a project. The glassfish log appears to be connecting to my database properly, it spits out all my table names and indices. However, I get an error INFO: fetching database metadata SEVERE: could not complete schema update java.lang.NullPointerException at interbase.interclient.ResultSet.local_Close(Unknown Source) ... And when I ping the connection pool from within Glassfish I receive "Ping failed Exception - null". I have the following properties set with my connectionpool: resource type: javax.sql.DataSource Datasource Classname: interbase.interclient.DataSource portNumber: 3050 as well as my database info. I can't seem to find information elsewhere. This question is similar but did not receive an answer. thanks.

• Is this valid EJB-QL?

  - by Yishai

  I have the following construct in EJB-QL several EJB 2.1 finder methods: SELECT distinct OBJECT(rd) FROM RequestDetail rd, DetailResponse dr WHERE dr.updateReqResponseParentID is not null and dr.updateReqResponseParentID = ?1 and rd.requestDetailID = dr.requestDetailID and rd.deleted is null and dr.deleted is null IDEA's EJB-QL inspection flags the use of the two object FROM RequestDetail rd, DetailResponse dr with an inspection which says: Several ranged variable declarations are not supported, use collection member declarations instead (e.g. IN(o.lineItems)) The queries themselves function fine (as in return the expected results) on JBoss 4.2. Is IDEA all wet here, or is there a valid issue with the query? And what is the actual preferred alternative syntax for such a query?

To simplify : Checkout certain sub-projects(modules) trunk of myprojectname Ex : http://mysvnurl/myprojectname/project1/trunk/* // get everything http://mysvnurl/myprojectname/project2/trunk/* // get everything How would I do that with maven, can someone with more expirience explain how to do this or point me to somewhere where I can read how to, I've googled nothing specific to my needs.
