Passing the backing bean as a parameter to a Facelet include

You can use <ui:param> for that. It needs to be nested in the <ui:include>. <ui:include src=”https://stackoverflow.com/questions/16842912/formView.xhtml”> <ui:param name=”ParameterBean” value=”#{Bean}” /> </ui:include> Unrelated to the concrete problem, standard Java Naming Conventions state that instance variable names must start with lower case. You should change your code in such way that respectively parameterBean and #{bean} will be … Read more

How do I include a common file in VBScript (similar to C #include)?

You can create a (relatively) small function in each file that you want to include other files into, as follows: sub includeFile (fSpec) dim fileSys, file, fileData set fileSys = createObject (“Scripting.FileSystemObject”) set file = fileSys.openTextFile (fSpec) fileData = file.readAll () file.close executeGlobal fileData set file = nothing set fileSys = nothing end sub and … Read more

What is a good reference documenting patterns of use of X-Macros in C (or possibly C++)?

I use X Macros() in code a lot. The value comes from only adding new data only to the “X list” and not modifying any other code. The most common use of X Macros() is for associating error text with error codes. When new error codes are added, programmers must remember to add the code … Read more

cmath vs math.h (And similar c-prefixed vs .h extension headers)

I’ve seen some information about differences between things like iostream vs iostream.h. [iostream.h] is not a standard header. it is not an example of the issue you’re raising. [cmath] defines symbols in the std namespace, and may also define symbols in the global namespace. [math.h] defines symbols in the global namespace, and may also define … Read more

Why gets() is deprecated? [duplicate]

Can someone explains why the compiler shows like that…? Yes, because, the gets() function is dangerous, as it suffers from buffer overflow issue. Anyone should refrain from using that. Also, regarding the warning with -Wdeprecated-declarations, gets() is no longer a part of C standard [C11 onwards]. So, C libraries compilers are not bound to support … Read more

How does #include work in C++?

No, #includes are transitive. However, if your second file itself uses symbols from someLibrary, it’s good style to re-include the header. That way you’re not “hoping and praying” that you never remove the intermediate include. Your codebase will be more robust if every source file #includes everything that it directly needs. Header guards prevent this … Read more

Do I have to use #include beside ?

Yes, you have to include what you use. It’s not mandated that standard headers include one another (with a few exceptions IIRC). It might work now, but might fail on a different compiler. In your case, apparently <iostream> includes <string>, directly or indirectly, but don’t rely on it.

What does the dot-slash do to PHP include calls?

./ is the current directory. It is largely the same as just file.php, but in many cases (this one included) it doesn’t check any standard places PHP might look for a file, instead checking only the current directory. From the PHP documentation (notice the last sentence): Files for including are first looked for in each … Read more

How to including variables within strings? [duplicate]

You can always use String.format(….). i.e., String string = String.format(“A String %s %2d”, aStringVar, anIntVar); I’m not sure if that is attractive enough for you, but it can be quite handy. The syntax is the same as for printf and java.util.Formatter. I’ve used it much especially if I want to show tabular numeric data.

How to get the file-path of the currently executing javascript code

Within the script: var scripts = document.getElementsByTagName(“script”), src = scripts[scripts.length-1].src; This works because the browser loads and executes scripts in order, so while your script is executing, the document it was included in is sure to have your script element as the last one on the page. This code of course must be ‘global’ to … Read more
