  • How to load image data from resource bitmap file for directshow filter ?

    - by Forrest
    I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it. First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1. Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer. So question is how to do this ? Or is that possible ? Thanks

  • How to communicate between service controller and a service/daemon?

    - by Sorin Sbarnea
    It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention. Please consider that you can have several controllers started at any time in a multi-user environment. Do you know an example(open source) for this kind of communication? Extra points for a platform independent solution :)

  • Benchmark of Java Try/Catch Block

    - by hectorg87
    I know that going into a catch block has some significance cost when executing a program, however, I was wondering if entering a try{} block also had any impact so I started looking for an answer in google with many opinions, but no benchmarking at all. Some answers I found were: Java try/catch performance, is it recommended to keep what is inside the try clause to a minimum? Try Catch Performance Java Java try catch blocks However they didn't answer my question with facts, so I decided to try it for myself. Here's what I did. I have a csv file with this format: host;ip;number;date;status;email;uid;name;lastname;promo_code; where everything after status is optional and will not even have the corresponding ; , so when parsing a validation has to be done to see if the value is there, here's where the try/catch issue came to my mind. The current code that in inherited in my company does this: StringTokenizer st=new StringTokenizer(line,";"); String host = st.nextToken(); String ip = st.nextToken(); String number = st.nextToken(); String date = st.nextToken(); String status = st.nextToken(); String email = ""; try{ email = st.nextToken(); }catch(NoSuchElementException e){ email = ""; } and it repeats what it's done for email with uid, name, lastname and promo_code. and I changed everything to: if(st.hasMoreTokens()){ email = st.nextToken(); } and in fact it performs faster. When parsing a file that doesn't have the optional columns. Here are the average times: --- Trying:122 milliseconds --- Checking:33 milliseconds however, here's what confused me and the reason I'm asking: When running the example with values for the optional columns in all 8000 lines of the CSV, the if() version still performs better than the try/catch version, so my question is Does really the try block does not have any performance impact on my code? The average times for this example are: --- Trying:105 milliseconds --- Checking:43 milliseconds Can somebody explain what's going on here? Thanks a lot

    - by atypicalgeek
    I'm planning on provisioning a web server and database server in a server farm environment. They will be in the same network but not in the same domain, both windows server 2008 and the database server is sql server 2008. My question being, what is the best way to secure data in transport between the servers? I've looked into IPSEC and SSL but not sure how to go about implementing either.

  • How to configure path to mappings to be used in hibernate.cfg.xml with maven (hbm2cfgxml)

    - by user342358
    Hi, can any one tell me how to force maven to precede mapping .hbm.xml files in the automatically generated hibernate.cfg.xml file with package path? My general idea is, I'd like to use hibernate-tools via maven to generate the persistence layer for my application. So, I need the hibernate.cfg.xml, then all my_table_names.hbm.xml and at the end the POJO's generated. Yet, the hbm2java goal won't work as I put *.hbm.xml files into the src/main/resources/package/path/ folder but hbm2cfgxml specifies the mapping files only by table name, i.e.: <mapping resource="MyTableName.hbm.xml" /> So the big question is: how can I configure hbm2cfgxml so that hibernate.cfg.xml looks like below: <mapping resource="package/path/MyTableName.hbm.xml" /> My pom.xml looks like this at the moment: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.2</version> <executions> <execution> <id>hbm2cfgxml</id> <phase>generate-sources</phase> <goals> <goal>hbm2cfgxml</goal> </goals> <inherited>false</inherited> <configuration> <components> <component> <name>hbm2cfgxml</name> <implemetation>jdbcconfiguration</implementation> <outputDirectory>src/main/resources/</outputDirectory> </component> </components> <componentProperties> <packagename>package.path</packageName> <configurationFile>src/main/resources/hibernate.cfg.xml</configurationFile> </componentProperties> </configuration> </execution> </executions> </plugin> And then the second question: is there a way to tell maven to copy resources to the target folder before executing hbm2java? At the moment I'm using mvn clean resources:resources generate-sources for that, but there must be a better way. Thanks for any help.

  • Windows Media Center, setting referer header

    - by Sha Le
    Hi I asked this question in SuperUser, posting here as well (http://superuser.com/questions/225671/windows-media-center-setting-referer-header). Is there a way to add REFERER header for any RTSP streams within Windows Media Center, I learned that REFERER header is only added when Windows Media Player is in a embed state. But I want to know that's true and also is there any plugin/addon. Thanks in advance.

  • Determining when or when not to escape output

    - by Ygam
    I have a page, where I have approximately 90 items I need to output. Most of them are object properties (I am using ORM so these objects map to my database tables). But the question is, do I have to escape each of those 90 outputs by applying functions to each (in my case, the htmlspecialchars)? Wouldn't that add a bit of an overhead (calling a single function 90 times)?

  • Can the adp2 device be flashed with 2.0?

    - by Rick Rodriguez
    Simple question...can the adp2 that I just bought through the Android Market be flashed with Android 2.0? I can't find anything anywhere. The HTC developer support only has system images for the adp1 and adp2 phones up to 1.6. If it can't I will be sending the phone back for a full refund. Thanks.

  • URL Controller Mapping Strategies (PHP)

    - by sunwukung
    This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one: http://stackoverflow.com/questions/125677/php-application-url-routing So far, I can ascertain two practices: 1: dynamic mapping through parsing the URL string (exploded on '/') 2: pattern matching matching url to config file containing available routes I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.

  • What are MVP and MVC and what is the difference?

    - by Wolfbyte
    When looking beyond the RAD (drag-drop and configure) way of building User Interfaces that many tools encourage you are likely to come across 2 design patterns called Model-View-Controller and Model-View-Presenter. My question has two parts to it: What issues do these patterns address? How are they similar? How are they different?
