• Failure when adding images to a thumbnail gallery

  - by Martin KS

  morning all, I've been browsing around trying to work out what I've done wrong when trying to add a thumbnail to a gallery view, but can't work out what on earth it might be. I'm trying to use the following code to stick a thumbnail onto a blank view: UIImageView *any = [[UIImageView alloc] initWithFrame:CGRectMake(a,b,70,60)]; any.image = [UIImage imageNamed:selectedThumbPath]; any.tag = 0; [self.view addSubview:any]; In the above example: a = 165 b = 150 selectedThumbPath = the full path to a thumbnail ie. /users/Cleverbum/library etc I'm pulling my hair out, there are no error messages, and no clues as to why it's not drawing anything. What's worse is that this is one of the only parts of the code i've not changed!

• Unable to use JAR in Eclipse

  - by Myn

  Hi guys, I have just created my first JAR in Eclipse, just a simple program with a single class Database.class. It is not in a package. public class Database { public Database() { int dbInit = 1; } } I have added it as an external JAR to the build path libraries for another project in Eclipse, but for some reason I cannot get Database db = new Database(), the default constructor, to work - it's as if the contents of the JAR are not being recognised. Could anyone please offer any advice on this? Thanks very much, M

• How to reference/link another project in grails workspace without using jar files?

  - by Ivan Alagenchev

  I have a Grails website that references a java core application. I have been successful in adding a .jar dependency to that project; however the java project is in the same workspace as my grails project and I would ultimately like to reference that project directly. I don't want to deal with the added step of creating a new jar file every time that there is a modification to the java project, cleaning and updating my dependencies. I added the java project to my grails' project "Java Build Path" and at first everything seemed to work fine, but when I run grailscompile, the compiler fails to resolve all imports that point to the java project. I am using Spring Source Toolsuite as my IDE.

• Java environmental variable woes, maven also

  - by Blankman

  So I re-installed java in a directory that doesn't have any spaces in it, as I was having issues with it before. Java JDK is installed in: E:\downloads\java\jdk I created a User variable: JAVA_HOME E:\downloads\java\jdk And my Path looks like: %JAVA_HOME%\bin;%M2%; Now opening a NEW cmd prompt: c:\java 'java' is not recognized... but echoing works: c:\echo %JAVA_HOME% E:\downloads\java\jdk and so does this: c:\%JAVA_HOME%\bin\java -version java version "1.6.0_17" I am trying to get this to work, so I can then get maven to work as maven is having the same type of issues (I created M2_HOME and M2 and none work). What exactly am I doing wrong? I am having the exact same issue on my laptop also, both are running windows 7. I must be missing something!

• ASP.Net website makes browser load unwanted (non-referenced) plugins

  - by alec0001

  I've found that some of my ASP.Net web apps prompt the browser to load plugins that I'm not explicitely using and certainly haven't deliberately referenced in the project settings. Two that come to mind are for MS MediaPlayer and the "SVG Viewer for Netscape". The only commonality I've determined so far is that the two sites/apps affected both use Master pages (nested in some cases). We don't use SVG file types (just the normal mix of jpg/gif/png) and no video/audio (not yet anyway). Can anyone provide a hint as to where the references for these might be creeping in? e.g. Is it a server-level include? Or a .Net runtime default when using master pages? Does anyone else even experience this, or is it just me? No urgency, I'd just like to remove it if possible. Thanks. Al

• How do I build two different installers from the same script in inno?

  - by Tim

  I want to make a "standard" install for external use, but I also want to use the same script and tell it (with a command line param perhaps?) to include another set of files (PDB files for debugging) for our lab installations. How can I do this? Is it possible? I don't see how to set this in the [files] section. NOTE - this is not for having an option during the install. It is for static build time. I suppose it is just best to create a separate installer for the pdbs.

• Strange macro declaration in C

  - by Andrey Atapin

  Exploring libusb-1.0.9 source code, I have found such line (./os/poll_windows.c:78): #define CHECK_INIT_POLLING do {if(!is_polling_set) init_polling();} while(0) As for me this is the same like: #define CHECK_INIT_POLLING if(!is_polling_set) init_polling(); Is there any reason to loop that expression? UPDATE: I couldn't still realize what'd be wrong after the answers, and the following example helped: #include <stdio.h> #define TEST if(test) foo(); #define TEST_DO do { if(test) foo(); } while(0) int test = 1; void foo() { printf("%s", "Foo called"); } int main(int argc, char** argv) { if(argc > 1) TEST_DO; /* LINE 12 */ else printf("%s", "skipping..."); return 0; } If you put TEST at line 12, a compiler will give an error "error: ‘else’ without a previous ‘if’". Hope, this will help someone.

• Timeout loading application on GAE using web2py

  - by Charles P.

  I am uploading an app to GAE. Through some experimentation I've found that if I don't include wsgihandler.py, the app loads very slowly. It feels like it's looking for this file and them timing out. Besides the slow loading, everything works perfectly without wsgihandler.py, so I want to know if there is a simple way to remove the references to the file. I tried poking around the files, but it doesn't look like there are direct references. Also, I asked before what I need at a minimum to get an application to work, and I found that I need: web2py/app.yaml web2py/gaehandler.py web2py/VERSION web2py/gluon/* (and subfolders, this is web2py) web2py/applications/theoneappyouwanttodeploy/* (and subfolders)

• Submit multiple forms as one

  - by Stephen Sarcsam Kamenar

  I have two forms on the page. To the user it looks like 1 form, and I actually wish it was one form. But the way I'm trying to reuse code and include things, I can't avoid two forms in the source code... trying to act as one. I don't want to do ajax submit, I want a normal post submit, my form handler has redirects in it. How can I submit both of these, and get values that make sense on the server side. something like $_POST['form1]['whatever'] $_POST['form2]['thing'] Maybe take all the inputs from form 2, rename all of them with a prefix, and append them to form 1? I can't find a non-messy way of doing this. I don't think I need code, just a plan. Least messy idea wins.

• Large amount of constants in Java

  - by Lars D

  I need to include about 1 MByte of data in a Java application, for very fast and easy access in the rest of the source code. My main background is not Java, so my initial idea was to convert the data directly to Java source code, defining 1MByte of constant arrays, classes (instead of C++ struct) etc., something like this: public final/immutable/const MyClass MyList[] = { { 23012, 22, "Hamburger"} , { 28375, 123, "Kieler"} }; However, it seems that Java does not support such constructs. Is this correct? If yes, what is the best solution to this problem?

• How does ‘Servers’ view work underlying in Eclipse?

  - by Michael Lu

  ‘Servers’ is built-in view in Eclipse. We could integrate jee server into Eclipse easily. It could start/stop server both in normal and debug modes. Moreover, we could even set timeout and deployment path, things like that. Various types of server tomcat, jboss, websphere are supported, no intrusive to server. I am just curious about how these cool things happen behind the scene. The complete mechanism is large and complex, so I just want to know general mechanism about it, an article also could be fine for me. Thank you!

• Deleting a cookie in Javascript not working

  - by DisgruntledGoat

  I have a site where authentication is done externally (which I can't access), so I'm creating a cookie on login in order to display a welcome message to the user. Creating the cookie works fine, I write to document.cookie when the login form submits. But deleting the cookie doesn't work. Here's my code (logout.php does the external authentication stuff): <a href="http://external.com/logout.php" style="float:right" onclick="document.cookie='BRLOG=; expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/; domain=.example.com;'">Logout</a>

• How to correctly migrate urls from custom asp.net solution to Wordpress?

  - by Marek

  I have a web site built using asp.net with ugly URLs like /DisplayContent.aspx?id=789564. I know how to migrate the database, but the Wordpress urls will be (naturally) different. Can I simply write some mapping or do I have to include a rewrite rule for each subpage (300 pages) in .htaccess? Should I provide a rewrite rule for each existing page that would transform a full old url to the known new url, like for example: /DisplayContent.aspx?id=789798 -> /2010-5-10/Title-Of-The-Post Even if I manage to migrate the URLs, the structure of the HTML for the new content will naturally be different. How does this affect SEO? Should I run asp.net and wordpress side by side and issue the redirects from the asp.net application? What is the most efficient solution to this kind of migration of URLs without doing PHP programming?

• how to find out if a shape is passable

  I have a complex polygon (possibly concave) and a few of its edges marked as entry/exit points. there is a possibility that inside this polygon may lie one or more blockades of arbitrary shape. what approaches could I use to determine whether a path of certain width exists between a pair of entry/exit edges? having read through the question it looks like a homework type - it is not. I just wish to have a at least a few leads I could pursue, as this is new to me.

• reStructured Text - Escape a headline?

  - by Rory

  I have a reStructuredText document. rST uses =====, etc. as a heading format. However I need to include some lines that have this text in it, e.g.: some of my text ===== stuff ===== some more of my text And I don't want the ==== to be interpreted as a heading, i.e. I don't want stuff to be a heading. I would rather that those equal signs are just displayed as is. Is this possible in rST?

• Linq to Entities (EF): How to get the value of a FK without doing the join

  - by Chu

  I'm using the Linq to Entities. I've got my main table, Employee setup with a field named vendorID. Vendor ID is a foreign key into the Vendors table. As it is right now, the Employee object does not directly expose the vendorID. Instead, I can only access it this way: var employee = (from e in context.Employees.Include("tbl_vendors") where e.employeeID = 1 select e).FirstOrDefault(); //this gets the vendor ID int vendorID = employee.tbl_vendors.vendorID; That is just fine and dandy, but it is extra work on the database because it is forcing a join where none is needed. Is there a way to get that key value without being forced to do a join to the tbl_vendors table?

• Change list link to foreign key change page

  - by Adam

  When viewing the admin change list for a model, is it possible to make the columns that correspond to foreign keys links to their respective pages? A simple example is I have a Foo object which contains Bar as a foreign key. If I'm viewing the admin change list for Foo (and have it set to include Bar in the display_list columns), the main column would link to the Foo instance's edit page while the Bar column would link to the Boo instance's edit page. I understand I can override the template that's used, but I was curious if there was a solution that didn't require that.

• Is there any way to view PHP code (the actual code not the compiled result) from a client machine?

  - by Columbo

  This may be a really stupid question...I started worrying last night that there might be someway to view PHP files on a server via a browser or someother means on a client machine. My worry is, I have an include file that contains the database username and password. If there were a way to put the address of this file in to a browser or some other system and see the code itself then it would be an issue for obvious reasons. Is this a legitimate concern? If so how do people go about preventing this?

• disallow certain url in robots.txt

  - by chrism

  We implemented a rating system on a site a while back that involves a link to a script. However, with the vast majority of ratings on the site at 3/5 and the ratings very even across 1-5 we're beginning to suspect that search engine crawlers etc. are getting through. The urls used look like this: http://www.thesite.com/path/to/the/page/rate?uid=abcdefghijk&value=3 When we started we add the following to our robots.txt: User-agent: * Disallow: /rate Is this incorrect or are googlebot and others simply ignoring our robots.txt?
