• Finding where varables have been declared in what file?

  - by robUK

  Hello, GNU Emacs 23.1.1 I am maintaining someones code. There are many files and directories for the headers and source files. I am wondering if there is a easy way to use emacs that when I highlight a variable name I can go straight to where it is declared? Some of the structures I am working in are declared in other header files, rather than go searching for them, I just want to be taken straight to them. Many thanks for any suggestions,

• Accessing object's method within string

  - by Wild One

  Recently I was reading php documentation and found interesting note in string section: Functions, method calls, static class variables, and class constants inside {$} work since PHP 5. However, the value accessed will be interpreted as the name of a variable in the scope in which the string is defined. Using single curly braces ({}) will not work for accessing the return values of functions or methods or the values of class constants or static class variables. See www.php.net/manual/en/language.types.string.php It says, that I can't use curly syntax to get value returned by object's method call. Is it a mistake in manual or I misunderstood it, because I tried the following code and it works just fine: <?php class HelloWorld { public static function hello() { echo 'hello'; } } $a = new HelloWorld(); echo "{$a->hello()} world";

• JSF managed bean question

  - by Nitesh Panchal

  Hello, I have one page which uses <ui:insert> called master.xhtml which uses one managedbean named MasterBean.java and its of viewScoped. It calls webservice and has all useful data which will be useful in master.xhtml as well as page which is built using master.xhtml (which uses <ui:include>). When i visit data.xhtml (which uses template as master.xhtml) and which uses managed bean as DataBean.java which is also of view scoped, how do i use MasterBean? If i directly use #{Masterbean.property}, won't it create a new instance again? or will it use the bean which is already in view scope? Also how do i use MasterBean in DataBean in such a way that existing MasterBean's instance is used in DataBean. I don't want new instance of MasterBean in DataBean. Thanks in advance. If i am not clear please let me know.

• Storing a type in C++

  - by perimosocordiae

  Is it possible to store a type name as a C++ variable? For example, like this: type my_type = int; // or string, or Foo, or any other type void* data = ...; my_type* a = (my_type*) data; I know that 99.9% of the time there's a better way to do what you want without resorting to casting void pointers, but I'm curious if C++ allows this sort of thing.

• movedown method not saving new position - cakephp tree

  - by Ryan

  Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

• glTexParameter and filtering in OpenGL and GLSL?

  - by sharoz

  I have a couple questions about glTexParameter and filtering 1) What is the scope when applying a glTexParameter (specifically the filtering)? Here's a scenario: Bind a texture. Set the filters to LINEAR Set the texture to "Sampler1" of a shader Bind another texture. Set its filters to NEAREST Set that texture to "Sampler2" of a shader Draw When I use the textures in a shader, will one be linear and the other be nearest? Or will they both be nearest because it was called last? 2) Is it possible to set the filtering method in GLSL? Thanks in advance!

• WinCheat / WinSpy-like tool for C++ Builder exes

  - by mawg

  I just came back to C++ Builder after 5 or more years away. I seem to remember a nice tool where I could drag its pointer over the GUI of my running application and get lots of info about what was pointed at - handle, size, text, parent, children, etc IIRC, if the exe include debug info I could also get the actual variable name as used in the source. Does anyone know what program I am talking about? Thanks
