  • Exception throws: encapsulate them or not?

    - by Simon
    Hi there. Once I read an MSDN article that encouraged the following programming paradigm: public class MyClass { public void Method1() { NewCustomException(); } public void Method2() { NewCustomException(); } void NewCustomException() { throw new CustomException("Exception message"); } } Do you think this paradigm makes sense? Wouldn't it be enough to store the exception message in a static const field and then pass it to the exception's constructor, instead of encapsulating the whole exception throw?

  • C#, Java, or SharePoint to learn

    - by bmw0128
    I know a bit of each of these, but none enough to pass technical phone screens/interviews. I am looking for a job, and I'll take anything, almost anywhere (in the US). Any opinions on which I should take on and do a deep dive? I do not which technology, I am wondering if one is better than the other when trying to get a job, more in the entry/mid level skill level. I am currently in the Bay Area, but will go anywhere.

  • Where are the clever uses of strict evaluation?

    - by devonrt
    It seems like there are plenty of examples of clever things being done in a lazily-evaluated language that can't be done in an environment with strict evaluation. For example infinite lists in Haskell or replacing every element in a tree with the tree's minimum value in one pass. Are there any examples of clever things being done in a strictly-evaluated language that can't easily be done in a lazily-evaluated language?

    - by Kyle
    I'm creating a paging class and need to pass in two parameters to my MySQL stored procedure for the LIMIT clause. I'm passing them in as INTs and trying something like this SELECT * FROM `MyTable` LIMIT MyFirstParamInt, MySecondParamInt it gives me an error when I try and save the sproc though. Is there a way to do this that I'm just missing? Or am I going to have to EVAL the whole query and EXECUTE it?

  • Registration with profile picture using services in Drupal

    - by Fran Ruano
    I've been trying to upload a user profile picture during the user registration using Service 3 and so far I haven't had any luck. I tested passing a hard coded fid in the field "picture" and also tried to pass the fields "filemime", "filename", etc. and it didn't work neither. Any idea about what fields I need to populate? I guess it must be related to this post Using Drupal Services and DIOS SDK for setting user picture in iOS app but it doesn't have and answer neither.

  • How to load image in correct pixel depth

    - by extropy
    I have a bunch of monochrome (1bpp) PNG images I want to load, and pass to pdfSharp. Using Image.FromFile loads images fine, but it alawys uses 32BPP, regardless of the pixel depth of the file. That results in very large PDF files generated. Is there a way to load images in their native pixel depth?

  • How do I change the auto complete behavior in the VS 2010 editor?

    - by pinkmuppet
    How do I stop VS 2010 (RC) from autocompleting html helpers with new object { ... } when I just want to pass in an anonymous type? Backspacing is driving me crazy. e.g., VS wants: <%=Html.ActionLink("Register", "Register", new object { controller = "Account" }) %> I know the helper is declared expecting object, which is why it does this, but can I change this behavior just for mvc helpers?

  • C++ vector of strings, pointers to functions, and the resulting frustration.

    - by Kyle
    So I am a first year computer science student, for on of my final projects, I need to write a program that takes a vector of strings, and applies various functions to these. Unfortunately, I am really confused on how to use pointer to pass the vector from function to function. Below is some sample code to give an idea of what I am talking about. I also get an error message when I try to deference any pointer. thanks. #include <iostream> #include <cstdlib> #include <vector> #include <string> using namespace std; vector<string>::pointer function_1(vector<string>::pointer ptr); void function_2(vector<string>::pointer ptr); int main() { vector<string>::pointer ptr; vector<string> svector; ptr = &svector[0]; function_1(ptr); function_2(ptr); } vector<string>::pointer function_1(vector<string>::pointer ptr) { string line; for(int i = 0; i < 10; i++) { cout << "enter some input ! \n"; // i need to be able to pass a reference of the vector getline(cin, line); // through various functions, and have the results *ptr.pushback(line); // reflectedin main(). But I cannot use member functions } // of vector with a deferenced pointer. return(ptr); } void function_2(vector<string>::pointer ptr) { for(int i = 0; i < 10; i++) { cout << *ptr[i] << endl; } }

  • Analyzing data for noisy arrays

    - by jimbo
    Using MATLAB I filtered a very noisy m x n array with a low-pass Gaussian filter, cleaned it up pretty well but still not well enough to analyze my data. What would the next step be? I'm thinking that signal enhancement, but am not sure how to go about this.

  • Should $new_link be used in mysql_connect()?

    - by Eddie
    I'm maintaining an inherited site built on Drupal. We are currently experiencing "too many connections" to the database. In the /includes/database.mysql.inc file, @mysql_connect($url['host'], $url['user'], $url['pass'], TRUE, 2) (mysql_connect() documentation) is used to connect to the database. Should $new_link = TRUE be used? My understanding is that it will "always open a new link." Could this be causing the "too many connections"?

My application will need to pass credentials & query to a Query_URL and receive the returned data.
