• About data size filled in the buffer

  - by Bohan Lu

  I need low-latency audio in my project, and I know Android 2.3 supports OpenSL ES. I have read documents and sample code and I decide to use Android simple buffer queue to do the play and record. I now try to write a simple application to do the test. However, I have some questions about recording. If I set the recorder stop when it is recording, how do I know the exact number of bytes filled in the last buffer if it is not filled up ? In 1.1 version, the callback function has some parameters about buffer and its filled data, but there is no such parameters in version 1.0.1. Is there any way to get this information ? Any suggestion would be greatly appreciated !

• Git: How to find all commits in branch A that originated in derived branch B merged back into A?

  - by Michael Ludwig

  In Git, given (1) a branch A and (2) a branch B derived from A at some point in the past and then merged back into A, how can I find all the commits now in A that originated in B? The intent is to identify the changeset of work performed in B now in A to more quickly track down issues. A squash commit would obviously and conveniently pack the entire changeset in one commit for easy reference, but the drawbacks (such as loss of information and individual attributability) make this option undesirable for us. Hence my question.

• Passing Results from SQL to Google Maps API in CodeIgniter

  - by Jason Shultz

  I'm hoping to use google maps on my site. My addresses are stored in a db. I’m pulling up a page where the information is all dynamic. For example: mysite.com/site/business/5 (where 5 is the id of the business). Let’s say I do a query like this: function addressForMap($id) { $this->db->select(‘b.id, b.busaddress, b.buscity, b.buszip’); $this->db->from(‘business as b’); $this->db->where(‘b.id, $id); } How can I output the info to the google maps api correctly so that it display’s the map appropriately? The API interface takes the results like this: $marker['address'] = 'Crescent Park, Palo Alto';

• How to get the position of a record in a table (SQL Server)

  - by Peter Siegmann

  Following problem: I need to get the position of a record in the table. Let's say I have five record in the table: Name: john doe, ID: 1 Name: jane doe, ID: 2 Name: Frankie Boy, ID: 4 Name: Johnny, ID: 9 Now, "Frankie Boy" is in the third position in the table. But How to get this information from the SQL server? I could count IDs, but they are not reliable, Frankie has the ID 4, but is in the third position because the record with the ID '3' was deleted. Is there a way? I am aware of ROW_RANK but it would be costly, because I need to select basically the whole set first before I can rank row_rank them. I am using MS SQL Server 2008 R2.

• How can I add a VS 2010 .Net 4.0 build agent to TFS 2008

  - by Mark Arnott

  My company has two development teams using TFS 2008. My team would like to migrate our .Net 3.5 app to the .Net 4.0 framework, but the company is not ready to upgrade TFS to TFS 2010. Can we still use TFS 2008's team build system but with a Visual Studio 2010 solution/project structure that targets the .Net 4.0 framework? I am thinking we would need to add a new build agent to TFS 2008 that would have VS 2010 installed. But I am not finding any information on how to do this. Is this possible? Are there any articles explaining how to do this?

  I try to pragrammatically run applications such as notepad.exe and Calc.exe with the following codes. I can see the application is activated in Process Exprorer but the application UI does not appear on the screen. I got this info inside the process p - "Process must exit before requested information can be determined" and the exitcode are 1200, 5084, etc. What is wrong? Thanks!

• Problem with update sql with excel

  Hi, I have a problem with this query: Update Provinces Set Provinces.DefaultName=T2.Defaultname from Provinces inner join OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:\provinces.xlsx;HDR=YES', 'SELECT Code, Defaultname FROM [Arkusz1$]') T2 On Provinces.Code = t2.Code where Provinces.Code = T2.Code I get error: Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" reported an error.

• HSQLDB and in-memory files

  - by lewap

  Is it possible to setup HSQLDB in a way, so that the files with the db information are written into memory instead of using actual files? I want to use hsqldb to export some data structures together with hibernate mappings. Is is, however, not possible to write temporary files, so that I need to generate the files in-memory and return a stream with their contents as a response. Setting hsqldb to use nio seems not to be a solution, because there is no way to get hold of those files before they get written onto the filesystem. What I'm thinking of is a protocol handler for hsqldb, but I didn't find a suitable solution yet. Just to describe in other words: A hack solution would be to pass hsqldb a stream or several streams. It would then during its operation write data into those streams. After all data is written, the user of the db could then use those streams to send it back over the network.

• Top tips for designing GUIs?

  - by oxbow_lakes

  A while back I read (before I lost it) a great book called GUI Bloopers which was full of examples of bad GUI design but also full of useful tidbits like Don't call something a Dialog one minute and a Popup the next. What top tips would you give for designing/documenting a GUI? It would be particularly useful to hear about widgets you designed to cram readable information into as little screen real-estate as possible. I'm going to roll this off with one of my own: avoid trees (e.g. Swing's JTree) unless you really can't avoid it, or have a unbounded hierarchy of stuff. I have found that users don't find them intuitive and they are hard to navigate and filter. PS. I think this question differs from this one as I'm asking for generalist tips

• How to analyse contents of binary serialization stream?

  - by Tao

  I'm using binary serialization (BinaryFormatter) as a temporary mechanism to store state information in a file for a relatively complex (game) object structure; the files are coming out much larger than I expect, and my data structure includes recursive references - so I'm wondering whether the BinaryFormatter is actually storing multiple copies of the same objects, or whether my basic "number of objects and values I should have" arithmentic is way off-base, or where else the excessive size is coming from. Searching on stack overflow I was able to find the specification for Microsoft's binary remoting format: http://msdn.microsoft.com/en-us/library/cc236844(PROT.10).aspx What I can't find is any existing viewer that enables you to "peek" into the contents of a binaryformatter output file - get object counts and total bytes for different object types in the file, etc; I feel like this must be my "google-fu" failing me (what little I have) - can anyone help? This must have been done before, right??

• Text code decoding

  - by Diana Villafane

  Hello. I am an English/Spanish Spanish/English translator. I have been given a job where I have to translate Spanish text messages sent from cell phones. Some of them are in code. I assume each set of figures represents a letter. Is there any website where I can find information on how to decipher the code? For instance, the first message says: ‘0x69 ox61 0x6e 0x70 0x72 0x2e 0x6e 0x65 0x74 0x2f 0x3f 0x64 0x34 0x39 0x31 0x66 0x30 0x37 0x38 0x35 0x35 0x32 0x39 0x62 0x36 0x31 0x31 0x00 Thank you for any help you provide.

• How to show a client-side message with Java JSF/Tobago?

  - by Marcus

  I have a web application created with JSF and Tobago. The user types some date into a sheet and clicks a button (all within one sheet-row). Now my java class checks whether the data is correct or not. In case there are some problems, I would like to show up something like a messagebox containing the errormessage. I cannot use something like JDialog, since this would happen only server side. Every user independently of his location needs to get the message. I thought about setting the error information into a databean and having my jsp show up the message after reloading. But how can I achieve this? Is there something like a tag which can be used for this? Or can I use the "confirmation" facet for this? But how would I start it without having the user to do something? Thanks in advance!

• How to monitor MySQL query errors, timeouts and logon attempts?

  - by Abel

  While setting up a third party closed source CMS (Sitefinity) the setup doesn't create all tables and procedures necessary to run it. The software lacks a logging system itself and it made me wonder: could I trace and monitor failing SQL statements from MySQL? This serves more than only the purpose of solving my issue with Sitefinity. More often I wonder what's send to the MySQL server, not wanting to dive into the software products or setup a debugging environment etc. I tried JetProfiler (only performance) and looked through a few others, but although they monitor a lot, they don't monitor query failures, timeouts or logon attempts. Does anyone know a profiler, tracer, monitoring tool, commercial or free, that can show me this information?

• What is the algorithm used by the memberwise equality test in .NET structs?

  - by Damian Powell

  What is the algorithm used by the memberwise equality test in .NET structs? I would like to know this so that I can use it as the basis for my own algorithm. I am trying to write a recursive memberwise equality test for arbitrary objects (in C#) for testing the logical equality of DTOs. This is considerably easier if the DTOs are structs (since ValueType.Equals does mostly the right thing) but that is not always appropriate. I would also like to override comparison of any IEnumerable objects (but not strings!) so that their contents are compared rather than their properties. This has proven to be harder than I would expect. Any hints will be greatly appreciated. I'll accept the answer that proves most useful or supplies a link to the most useful information. Thanks.

  I have a c#/winforms application that uses directx to play some video and audio. whenever i start my application in debugmode i get this annoying message. i can click "continue" and everything seems to work fine. but i still want to get rid of this message. it does not show up in releasemode. Managed Debugging Assistant 'LoaderLock' has detected a problem in 'C:\pathtoexe.exe'.

• Removing part of a branch

  - by benPearce

  In our codebase we are using the following structure, using TFS / - Build - Development - Dev1 - Dev2 - Main - Releases - Rel1 - Rel2 The Development and Releases sections contain branches off main. The Build section sits outside the branching. Within each of the branches there is a section which should not have been included within the branching which I would like to move under Build. Is it possible to move this section out and remove its branching information? If I do a rename what impact might this have when creating new branches or merging?

• Is there any software made by microsoft using .NET?

  - by SnOrfus

  I've been reading some blogs and articles lately and one thing I noticed a couple of times was authors stating that Microsoft 'doesn't use their own technologies' with respect to developing applications using the .NET framework (specifically, desktop applications). There's not a whole lot of information that I can see as to what platforms their products are developed with. I had heard that Media Center has some .NET code, but not 100%, likewise with SQL Server Management Studio. So the question I ask is, does anyone know of any software, made by Microsoft that is 100% .NET code?

• Designing a frontend/backend architecture

  - by wrp

  What are some good information sources on designing programs with a client/server architecture? This is for development of a desktop application, not a Web service. The only books I have found on client/server apps deal with the case of a thin client connecting to a remote database. Two good examples of what I mean are Mathematica and SuperCollider. I'm looking for platform- and language-agnostic discussion of the issues in developing a frontend/backend system. Especially useful topics would be allocation of responsibilities and options for message passing.

• Multiple children in single form in rails

  - by CaptnCraig

  I have a model that has an arbitrary number of children entities. For simplicity lets call the entities Orders and Items. I would like to have a create Orders form where I input the order information, as well as add as many items as I want. If I click the "Add another item" button, a new set of form elements will be added to input the new data, amounts, etc.. I could hack this out in pure javascript, but I'm pretty sure there has to be a more magical, railsish way to do it, maybe with a partial view or something. I'm just a little too new to rails to know what it is. What is the best way to dynamically add the new form elements, and then to access them in the create controller?

• What is the best way in Silerlight to make areas of a large graphic clickable?

  - by Edward Tanguay

  In a Silverlight application I have large images which have flow charts on them. I need to handle the clicks on specific hotspots of the image where the flow chart boxes are. Since the flow charts will always be different, the information of where the hotspots has to be dynamic, e.g. in a list of coordinates. I've found article like this one but don't need the detail of e.g. the outline of countries but just simple rectangle and circle areas. I've also found articles where they talk about overlaying an HTML image map over the silverlight application, but it has to be easier than this. What is the best way to handle clicks on specific areas of an image in silverlight?

• What lessons can you learn from software maintanence?

  - by Vasil Remeniuk

  Hello everyone, In the perfect world, all the software developers would work with the cutting edge technologies, creating systems from the scratch. In the real life, almost all of us have to maintain software from time to time (unlucky ones do it on a regular basis). Personally I first 2 years of my career was fixing bugs in the company that no longer exists (it has been taken up by Oracle). And probably the biggest lesson I've learned that time - despite of the pressure, always try to get as much information about the domain as possible (even if it's irrelevant to fixing a specific bug or adding a feature) - abstract domain knowledge doesn't lose value as fast as knowledge about trendy frameworks or methodologies. What lessons have you learned from maintenance?

• Paypal Payflow pro library

  - by John Stewart

  I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?
