• WinSock best accept() practices

  - by Meta

  Imagine you have a server which can handle only one client at a time. The server uses WSAAsyncSelect to be notified of new connections. In this case, what is the best way of handling FD_ACCEPT messages: A Accept the connection attempt right away but queue the client until its turn? B Do not accept the next connection attempt until we are done serving the currently connected client? What do you guys think is the most efficient?

• I need a row Added event for a DataGridView

  - by tizzyfoe

  What i want to do is set the background of a row based on some criteria, but the datagrid will be fairly large so i don't want to have to loop over all the rows again. The rows get created me doing something like "myDataGridView.DataSource = MyDataSource, so the only way i can think to edit rows is by using an event. there is a row*s* added event, but that gives me a list of rows that i'd have to iterate over. Thanks in advance for any help.

• NullDisplayText in markup vs ISNULL(field, 0) in SQL?

  - by abatishchev

  Which approach is better to use: BoundField.NullDisplayText isn't set. NULL-case is foreseen in SQL query, i.e. SELECT ISNULL(amount, 0) FROM table or BoundField.NullDisplayText is set, e.g. "0.00 %". NULL-case isn't foreseen in SQL query, i.e. SELECT amount FROM table What do you think?

• Is there a good Python library that can parse C++?

  - by csbrooks

  Google didn't turn up anything that seemed relevant. I have a bunch of existing, working C++ code, and I'd like to use python to crawl through it and figure out relationships between classes, etc. EDIT: Just wanted to point out: I don't think I need or want to parse every bit of C++; I just need something smart enough to pick up on class, function and member variable declarations, and to skip over function definitions.

• Are Objective-C function names stored in text?

  - by thyrgle

  I don't remember where I heard about it, (I think I was searching up on how selectors worked and it ended up not being exactly the same as a callback function) and I can't confirm it. But more importantly than that, is there a way I could get a list of the function names from another application?

• R: How to replace elements of a data.frame?

  - by John

  I'm trying to replace elements of a data.frame containing "#N/A" with "NULL", and I'm running into problems: foo <- data.frame("day"= c(1, 3, 5, 7), "od" = c(0.1, "#N/A", 0.4, 0.8)) indices_of_NAs <- which(foo == "#N/A") replace(foo, indices_of_NAs, "NULL") Error in [<-.data.frame(*tmp*, list, value = "NULL") : new columns would leave holes after existing columns I think that the problem is that my index is treating the data.frame as a vector, but that the replace function is treating it differently somehow, but I'm not sure what the issue is?

• Why isn't there a $('.someSelector').id() method in jQuery?

  - by Jason

  I was wondering if anyone knew why jQuery doesn't have a simple $().id() method. It seems silly to have to pull the id using $().attr('id'). I would think that the id attribute was common and useful enough to have its own call.

• Calendar add() vs roll() when do we use it?

  - by Pentium10

  I know add() adds the specified (signed) amount of time to the given time field, based on the calendar's rules. And roll() adds the specified (signed) single unit of time on the given time field without changing larger fields. I can't think of an everyday usage of roll() I would do everything by add(). Can you help me out with examples when do we use roll() and when add()?

• SOAP vs REST (differences)

  - by Abdulaziz

  I have read articles about the differences between SOAP and REST as a web service communication protocol, but I think that the biggest advantage for REST over SOAP are : REST is more dynamic, no need for creating and updating UDDI. REST is not restricted to XML format. REST web services can send plain text, JSON, and also XML. But SOAP is more standardized (Ex; security). So, am I correct in these points? Thanks
