  • Attaching .swf assets to Flex3 by calling getDefinitionByName()

    - by Alexander Farber
    Hello! Does anybody please know, how could you attach symbols from an .swf file in the Actionscript part of your Flex3 file? I've prepared a simple test case demonstrating my problem. Everything works (there are icons at the 4 buttons, there is a red circle) - except the getDefinitionByName() part. My target is to attach a symbol from library "dynamically" - i.e. depending at the value of the suit variable at the runtime. Thank you, Alex Symbols.as: package { public class Symbols { [Embed('../assets/symbols.swf', symbol='spades')] public static const SPADES:Class; [Embed('../assets/symbols.swf', symbol='clubs')] public static const CLUBS:Class; [Embed('../assets/symbols.swf', symbol='diamonds')] public static const DIAMONDS:Class; [Embed('../assets/symbols.swf', symbol='hearts')] public static const HEARTS:Class; } } TestCase.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete();"> <mx:Script> <![CDATA[ private function onCreationComplete():void { var sprite:Sprite = new Sprite(); var g:Graphics = sprite.graphics; g.lineStyle(1, 0xFF0000); g.beginFill(0xFF0000); g.drawCircle(100, 100, 20); g.endFill(); spriteHolder.addChild(sprite); // XXX stuff below not working, can it be fixed? var suit:String = "SPADES"; var mc:MovieClip = new (getDefinitionByName("Symbols.SPADES") as Class); spriteHolder.addChild(mc); } ]]> </mx:Script> <mx:VBox width="100%"> <mx:Button label="1" icon="{Symbols.SPADES}" /> <mx:Button label="2" icon="{Symbols.CLUBS}" /> <mx:Button label="3" icon="{Symbols.DIAMONDS}" /> <mx:Button label="4" icon="{Symbols.HEARTS}" /> <mx:UIComponent id="spriteHolder" width="200" height="200"/> </mx:VBox> </mx:Application>

  • calling CreateFile, specifying FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE.

    - by alexander-daniels
    Before I describe my problem, here is a description of the program I'm writting: This is a C++ application. The purpose of my program is to create file on RAM memory. I read that if specify FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE when creating file it will be loaded direct to the RAM memory. One of blogs that talk about is this one: http://blogs.msdn.com/larryosterman/archive/2004/04/19/116084.aspx I have built a mini-program, but it not achieves the goal. Instead, it creates a file on hard-drive on directory I specify. Here's my program: void main () { LPCWSTR str = L"c:\temp.txt"; HANDLE fh = CreateFile(str,GENERIC_WRITE,0,NULL,CREATE_ALWAYS, FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE,NULL); if (fh == INVALID_HANDLE_VALUE) { printf ("Could not open TWO.TXT"); return; } DWORD dwBytesWritten; for (long i=0; i<20000000; i++) { WriteFile(fh, "This is a test\r\n", 16, &dwBytesWritten, NULL); } return; } I think there problem in CreateFile function, but I can't fix it. Please help me.

  • iPhone HUD style progress bar

    - by Alexander
    I've been wanting to create a HUD style loading bar like the SMS app on the iPhone used to have (http://www.jonokane.com/images/blog/iphoneFixProblem.jpg) but don't know how. I was wondering if anyone has done this before or if there is a tutorial somewhere for it? I just think it looks so nice and would like to use it rather than the built in loading progress bar. Thanks a bunch!

  • TimeoutException in simultaneous calls to WCF services from Silverlight application

    - by Alexander K.
    Analysing log files I've noticed that ~1% of service calls ended with TimeoutException on the Silverlight client side. The services (wcf) are quite simple and do not perform long computations. According the log all calls to the services are always processed in less that 1 sec (even when TimeoutException is occurred on the client!), so it is not server timeout. So what is wrong? Can it be configuration or network problem? How can I avoid it? What additional logging information can be helpful for localizing this issue? The only one workaround I've thought up is to retry service calls after timeout. I will appreciate any help on this issue! Update: On startup the application performs 17 service calls and 12 of them simultaneously (may it be cause of failure?). Update: WCF log has not contained useful information about this issue. It seems some service calls do not reach the server side.

  • Is NSNumberFormatter the only way to format an NSDecimalNumber?

    - by Paul Alexander
    I'm using an NSDecimalNumber to store money in Core Data. I naively used stringWithFormat: at first to format the value, later realizing that it didn't support NSDecimalNumber and was instead formatting the pointer :(. So after some reading through the docs I learned to use the NSNumberFormatter to get the format I wanted. But this just strikes me as the "hard way". Is there any easier way than this:? NSNumberFormatter * formatter = [[NSNumberFormatter alloc] init]; [formatter setNumberStyle: NSNumberFormatterCurrencyStyle]; priceField.text = [formatter stringFromNumber: ent.price]; [formatter release];

  • flush output in Bourne Shell

    - by n-alexander
    I use echo in Upstart scripts to log things: script echo "main: some data" >> log end script post-start script echo "post-start: another data" >> log end script Now these two run in parallel, so in the logs I often see: main: post-start: some data another data This is not critical, so I won't employ proper synching, but thought I'd turn auto flush ON to at least reduce this effect. Is there an easy way to do that? Update: yes, flushing will not properly fix it, but I've seen it help such situations to some degree, and this is all I need in this case. It's just that I don't know how to do it in Shell

  • SQL Server 2008: FileStream Insertion Failure w/ .NET 3.5SP1

    - by James Alexander
    I've configured a db w/ a FileStream group and have a table w/ File type on it. When attempting to insert a streamed file and after I create the table row, my query to read the filepath out and the buffer returns a null file path. I can't seem to figure out why though. Here is the table creation script: /****** Object: Table [dbo].[JobInstanceFile] Script Date: 03/22/2010 18:05:36 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[JobInstanceFile]( [JobInstanceFileId] [int] IDENTITY(1,1) NOT NULL, [JobInstanceId] [int] NOT NULL, [File] [varbinary](max) FILESTREAM NULL, [FileId] [uniqueidentifier] ROWGUIDCOL NOT NULL, [Created] [datetime] NOT NULL, CONSTRAINT [PK_JobInstanceFile] PRIMARY KEY CLUSTERED ( [JobInstanceFileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup], UNIQUE NONCLUSTERED ( [FileId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] FILESTREAM_ON [JobInstanceFilesGroup] GO SET ANSI_PADDING OFF GO ALTER TABLE [dbo].[JobInstanceFile] ADD DEFAULT (newid()) FOR [FileId] GO Here's my proc I call to create the row before streaming the file: /****** Object: StoredProcedure [dbo].[JobInstanceFileCreate] Script Date: 03/22/2010 18:06:23 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO create proc [dbo].[JobInstanceFileCreate] @JobInstanceId int, @Created datetime as insert into JobInstanceFile (JobInstanceId, FileId, Created) values (@JobInstanceId, newid(), @Created) select scope_identity() GO And lastly, here's the code I'm using: public int CreateJobInstanceFile(int jobInstanceId, string filePath) { using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConsumerMarketingStoreFiles"].ConnectionString)) using (var fileStream = new FileStream(filePath, FileMode.Open)) { connection.Open(); var tran = connection.BeginTransaction(IsolationLevel.ReadCommitted); try { //create the JobInstanceFile instance var command = new SqlCommand("JobInstanceFileCreate", connection) { Transaction = tran }; command.CommandType = CommandType.StoredProcedure; command.Parameters.AddWithValue("@JobInstanceId", jobInstanceId); command.Parameters.AddWithValue("@Created", DateTime.Now); int jobInstanceFileId = Convert.ToInt32(command.ExecuteScalar()); //read out the filestream transaction context to stream the file for storage command.CommandText = "select [File].PathName(), GET_FILESTREAM_TRANSACTION_CONTEXT() from JobInstanceFile where JobInstanceFileId = @JobInstanceFileId"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@JobInstanceFileId", jobInstanceFileId); using (SqlDataReader dr = command.ExecuteReader()) { dr.Read(); //get the file path we're writing out to string writePath = dr.GetString(0); using (var writeStream = new SqlFileStream(writePath, (byte[])dr.GetValue(1), FileAccess.ReadWrite)) { //copy from one stream to another byte[] bytes = new byte[65536]; int numBytes; while ((numBytes = fileStream.Read(bytes, 0, 65536)) 0) writeStream.Write(bytes, 0, numBytes); } } tran.Commit(); return jobInstanceFileId; } catch (Exception e) { tran.Rollback(); throw e; } } } Can someone please let me know what I'm doing wrong. In the code, the following expression is returning null for the file path and shouldn't be: //get the file path we're writing out to string writePath = dr.GetString(0); The server is different then the computer the code is running on but the necessary shares appear to be in order and I have also run the following: EXEC sp_configure filestream_access_level, 2 Any help would be greatly appreciated. Thanks!

  • How to update model?

    - by Alexander Efimov
    Hi, guys. I have an ASP.NET MVC page where the model is being edited. On each action executing I have a new controller, so I don't get an updated model. I'm saving a model instance into Session["MyModelKey"]. But every time an action is executed, I have unmodified instance there even if I have changed values in textboxes which were created like this: @Html.LabelFor(model = model.EMail) @Html.TextBoxFor(model = model.EMail) @Html.LabelFor(model = model.Country) @Html.TextBoxFor(model = model.Country) @Html.ActionLink("MyAction", "MyController") Controller: public class MyController : Controller { public ActionResult MyAction() { //Every time this action is executed - I have a new controller instance //So I have null in View.Model //I get Session["MyModelKey"] here, //But the model instance properties are not updated //even though I have updated E-mail and Country properties of the model in the UI } } So, how can I get an updated model? Thanks in advance.

  • JavaScript variable to ColdFusion variable

    - by Alexander
    I have a tricky one. By means of a <cfoutput query="…"> I list some records in the page from a SQL Server database. By the end of each line viewing I try to add this in to a record in a MySQL database. As you see is simple, because I can use the exact variables from the output query in to my new INSERT INTO statement. BUT: the rsPick.name comes from a database with a different character set and the only way to get it right into my new database is to read it from the web page and not from the value came in the output query. So I read this value with that little JavaScript I made and put it in the myValue variable and then I want ColdFusion to read that variable in order to place it in my SQL statement. <cfoutput query="rsPick"> <tr> <td>#rsPick.ABBREVIATION#</td> <td id="square"> #rsPick.name# </td> <td>#rsPick.Composition#</td> <td> Transaction done... <script type="text/javascript"> var myvalue = document.getElementById("square").innerHTML </script> </td> <cfquery datasource="#Request.Order#"> INSERT INTO products (iniid, abbreviation, clsid, cllid, dfsid, dflid, szsid, szlid, gross, retail, netvaluebc, composition, name) VALUES ( #rsPick.ID#, '#rsPick.ABBREVIATION#', #rsPick.CLSID#, #rsPick.CLLID#, #rsPick.DFSID#, #rsPick.DFLID#, #rsPick.SZSID#, #rsPick.SZLID#, #rsPick.GROSSPRICE#, #rsPick.RETAILPRICE#, #rsPick.NETVALUEBC#, '#rsPick.COMPOSITION#','#MYVALUE#' ) </cfquery> </tr> </cfoutput>

  • Animating a CALayer's mask size change

    - by Alexander Repty
    I have a UIView subclass which uses a CAShapeLayer mask on its CALayer. The mask uses a distinct shape, with three rounded corners and a cut out rectangle in the remaining corner. When I resize my UIView using a standard animation block, the UIView itself and its CALayer resize just fine. The mask, however, is applied instantly, which leads to some drawing issues. I've tried animating the mask's resizing using a CABasicAnimation but didn't have any luck getting the resizing animated. Can I somehow achieve an animated resizing effect on the mask? Do I need to get rid of the mask, or will I have to change something about the way I currently draw the mask (using - (void)drawInContext:(CGContextRef)ctx). Cheers, Alex

  • [SQL] Full-text search CONTAINSTABLE

    - by Alexander Vanwynsberghe
    Hello, I have a question regarding a CONTAINSTABLE function. I would like to find everything that ENDS WITH the search string. I can use the * to find everything that starts with the searchvalue, but I want an equivalent for the % sign in the SQL LIKE function. What I want: find everything that ends with 123, so as searchvalue, I could use "*123" in my CONTAINSTABLE function. But that doesn't work.. If I want all results starting with 123, I use "123*", and that works well. But what's the equivalent for -- LIKE %123 ?? it isn't "*123" in the CONTAINSTABLE function. What is it then? Thanks!

  • MIPS return address in main

  • Animating custom-drawn UITableViewCell when entering edit mode

    - by Adam Alexander
    Background First of all, much gratitude to atebits for their very informative blog post Fast Scrolling in Tweetie with UITableView. The post explains in detail how the developers were able to squeeze as much scrolling performance as possible out of the UITableViews in Tweetie. Goals Beginning with the source code linked from the blog post (original) (my github repo): Allow a UITableView using these custom cells to switch to edit mode, exposing the UI for deleting an item from the table. (github commit) Move the cell's text aside as the deletion control slides in from the left. This is complete, although the text jumps back and forth without animation. (github commit) Apply animation to the text movement in goal 2 above for a smooth user experience. This is the step where I became stuck. The Question What is the best way to introduce this animation to complete goal 3? It would be nice if this could be done in a manner that keeps the logic from my last commit because I would love the option to move the conflicting part of the view only, while any non-conflicting portions (such as right-justified text) stay in the same place or move a different number of pixels. If the above is not possible then undoing my last commit and replacing it with an option that slides the entire view to the right would be a workable solution also. I appreciate any help anyone can provide, from quick pointers and ideas all the way to code snippets or github commits. Of course you are welcome to fork my repo if you would like. I will be staying involved with this question to make sure any successful resolution is committed to github and fully documented here. Thanks very much for your time! Updated thoughts I have been thinking about this a lot since my first post and realized that moving some text items relative to others in the view could undo some of the original performance goals solved in the original blog post. So at this point I am thinking a solution where the entire single subview is animated to its new postion may be the best one. Second, if it is done in this way there may be an instance where the subview has a custom color or gradient background. Hopefully this can be done in a way that in its normal position the background extends unseen off to the left enough so that when the view is slid to the right the custom background is still visible across the entire cell.
