  • What are the requirments for ISupportInitialize code to be serialized in InitializeComponent? .Net

    - by Jules
    I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net. What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control. Is that the minimum requirement?

  • What was the most refreshingly honest non-technical comment you saw in the code?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored proc, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • How to make a macro which gives back a string into the source code?

    - by mystify
    Example: I want to do this: METHODNAME(5) { // do something } which results in: - (void)animationStep5 { // do something } Is there any way to do this? Basically, what I need is a way to generate a real source code string before the program is compiled, so the compiler does see - (void)animationStep5... Or maybe there's something different than a macro, which can help here to auto-generate method names (not at run-time)?

  • Custom components vs default components in GUI Design. Which is more practical? (.NET)

    - by AlexRednic
    Ok, so is it better to create my own components (Either inherit them from existing ones or creating them from scratch) or to use the ones that come by default? I'm asking this under the umbrella of scalability, overhead and other factors that my contribute on each of the choices. UPDATE: Sorry if I'm to vague. I don't really know how to explain myself better. Isn't it a good idea to inherit each default component? For example what if I'm to design a rather large application and for example i need to change the display format on a DateTimePicker. Wouldn't it better to think ahead and inherit it and use the inherited component instead of the defaults? But, wouldn't it add a lot of overhead in small applications?

  • Better way to implement custom views in a listview with simpleadapter?

    - by jonaz
    I have a value called tags which is a comma separated list of words. I want to put this into nicely designed "tag-buttons". The below works. However the line ((LinearLayout) view).removeAllViews(); seems like an ugly fix for not adding the tags multiple times every time adapter.notifyDataSetChanged(); is called after i load more rows with a setOnScrollListener() Any suggestion to "best practice" here, or at least a more good looking solution? adapter = new SimpleAdapter(activity,data, R.layout.list_transactions, new String[] {"comment", "amount","date","tags","category"}, new int[] { R.id.comment, R.id.amount,R.id.date,R.id.tags_container,R.id.category } ); SimpleAdapter.ViewBinder binder = new SimpleAdapter.ViewBinder() { @Override public boolean setViewValue(View view, Object object, String value) { //Log.d(TAG,"view.toString()= "+ view.toString()); if (view.getId() == R.id.tags_container) { String[] tags = value.split(","); ((LinearLayout) view).removeAllViews(); for (String tag : tags) { View v = createTagView(activity.getLayoutInflater(),tag); ((LinearLayout) view).addView(v); } return true; } return false; } };

  • How to safely let users run arbitrary Ruby code?

    - by igul222
    I realize this sounds a little crazy, but I'm working on a project for which I need a server to run user-provided Ruby code and return the result. I'm looking to prevent something like this: system("rm -rf /") eval("something_evil") # etc... I'm sure there must be some reasonably safe way to do this, as it already exists at places like tryruby.org. Any help is greatly appreciated, thanks!

  • How to convert a string color to its hex code or RGB value?

    - by Abs
    Hello all, I am not sure if its possible but I would like to create some sort of function where you pass in a string such as "yellow" or "green" and it returns its hex code or the range of hex codes that greens or yellows fit into. Is this possible in PHP? If not possible, I am willing to try anything else that can do this! Thanks all

  • WPF custom user widgets. Will UI components be standardized?

    - by Andrew Florko
    There are lots of articles and video lessons that describe how to create your unique user widget (graphical control) with WPF. There are tons of technical details what is behind the scene and I feel people enthusiasm with ability to customize widgets as never before. I remember those days when VCL library (Delphi) appeared and there was the same enthusiasm in VCL widgets area. Ability to create VCL controls was nearly the must when you was applying for a job as Delphi developer. This situation continued for several years till professional sophisticated 3'd party UI libraries appeared. Hardly you'll have to create your own VCL widget nowadays. Will WPF widgets enthusiasm die as VCL one?

  • Is there any library to represent SQL queries as objects in Java code?

    - by Pregzt
    I was wondering if there is any library that can be used to represent SQL queries as objects in Java. In the code I have plenty of static variables of type java.lang.String that are hand written SQL queries. I would be looking for library having a nice fluent API that allows me to represent the queries as objects rather than strings. Example: Query q = select("DATE", "QUOTE") .from("STOCKMARKET") .where(eq("CORP", "?")) .orderBy("DATE", DESC);

  • How does C++ free the memory when a constructor throws an exception and a custom new is used

    - by Joshua
    I see the following constructs: new X will free the memory if X constructor throws. operator new() can be overloaded. The canonical definition of an operator new overload is void *operator new(heap h) and the corrisponding operator delete. The most common operator new overload is pacement new, which is void *operator new(void *p) { return p; } You almost always cannot call delete on the pointer given to placement new. This leads to a single question. How is memory cleaned up when X constructor throws and an overloaded new is used?

  • How to write a custom predicate for multi_index_containder with composite_key?

    - by Titan
    I googled and searched in the boost's man, but didn't find any examples. May be it's a stupid question...anyway. So we have the famous phonebook from the man: typedef multi_index_container< phonebook_entry, indexed_by< ordered_non_unique< composite_key< phonebook_entry, member<phonebook_entry,std::string,&phonebook_entry::family_name>, member<phonebook_entry,std::string,&phonebook_entry::given_name> >, composite_key_compare< std::less<std::string>, // family names sorted as by default std::greater<std::string> // given names reversed > >, ordered_unique< member<phonebook_entry,std::string,&phonebook_entry::phone_number> > > > phonebook; phonebook pb; ... // look for all Whites std::pair<phonebook::iterator,phonebook::iterator> p= pb.equal_range(boost::make_tuple("White"), my_custom_comp()); How should my_custom_comp() look like? I mean it's clear for me then it takes boost::multi_index::composite_key_result<CompositeKey> as an argumen (due to compilation errors :) ), but what is CompositeKey in that particular case? struct my_custom_comp { bool operator()( ?? boost::multi_index::composite_key_result<CompositeKey> ?? ) const { return blah_blah_blah; } }; Thanks in advance.
