• Changing directory in Open File Dialog programatically.

  - by ofarooq

  Hi All, I have a customized OpenFileDialog (VS2008, C#, Windows Forms) with a ComboBox. The ComboBox will have a list of paths which the user can select. My question, is there a way I can change the directory in Open File Dialog to point to the path in the combobox selected item. InitialDirectory works only before I open the dialog, I wanted a way to change the directory programatically after the dialog is open. Thanks

• How do I stop Emacs automatically inserting hyphens at the beginning of new lines in fundamental fil

  - by Bryce Thomas

  Hi there, I'm jotting down some notes in Emacs in Fundamental Fill mode. I'm starting each one of my notes with a "-" on a new line. The problem is, whenever one of the notes I'm writing is too long to fit on a single line, it gets pushed down to the next line (which I want to happen) but Emacs goes ahead and automatically inserts another "-" for me out the front on the new line (which I don't want to happen). Is there a way to stop Emacs from exhibiting this "helpful" behaviour?

• SVN Source control issues when merging changes

  - by HollyStyles

  I have seen where changes have been made on one code file by two developers code like this: x++ End up like this: x++ x++ where due to carriage returns being inserted/removed (I think) one line has become silently merged as two lines of the same code (no conflicts) Everything compiles but suddenly tests are failing and weird behaviour ensues. Should this be possible? How do I guard against it?

• HTTP GET: Same GET-Parameter multiple Times, is this allowed by RFCs?

  - by bernhard

  Hello, are all "Standard Compliant (HTTP RFC?)" Web-Servers forced to "somehow" provide some methods to get all Parameters with the same name as some kind of list/array? Or will will using the same parameter name lead to overwriting: Example: http://www.stackoverflow?myparam=value1&myparam=value2 Will this lead to myparam holding the values "value1,value2" or only "value2" (due to overwriting and only using the last one). Is this behaviour mandated by some standard? thanks bernhard
