• Apache Virtual Host in Windows - how do I deal with Symbolic links?

  - by Peeaytchpee

  Hi Folks, I'm trying to run a virtual host on a WAPP stack. My virtual host has the FollowSymLinks option, but in Windows, all those symbolic links (I'm using shortcuts, and I think this may be the problem) have the .lnk extension. So if I'm trying to access settings.html, Apache can't find it because all i have sitting there is settings.html.lnk. Apologies if my question is unclear.

• How to replace only part of the match with python re.sub

  - by Arty

  I need to match two cases by one reg expression and do replacement 'long.file.name.jpg' - 'long.file.name_suff.jpg' 'long.file.name_a.jpg' - 'long.file.name_suff.jpg' I'm trying to do the following re.sub('(\_a)?\.[^\.]*$' , '_suff.',"long.file.name.jpg") But this is cut the extension '.jpg' and I'm getting long.file.name_suff. instead of long.file.name_suff.jpg I understand that this is because of [^.]*$ part, but I can't exclude it, because I have to find last occurance of '_a' to replace or last '.' Is there a way to replace only part of the match?

• Does a lazy-programmer "document template" with tags exist for Windows?

  - by Anthony Forloney

  I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Does one, or could one, exist, preferably Windows based? Any information regarding this would be helpful.

• Javascript click function

  - by Gordon Carpenter-Thompson

  I've got some code which works fine in IE but unfortunately not in Google Chrome/Firefox. It relies upon calling a click() event on a button from javascript. Reading around it seems that this is an IE specific extension (doh). Is there any way I can do a similar thing in chrome + firefox? Thanks

• Error log of make command in Linux

  - by dexkid

  I am compiling a kernel module and it has many compilation errors in it. After running "make", the errors thrown out are too many to fit in the screen. Scrolling up doesn't reach the first error. I tried capturing the errors by doing make &2 log which didn't work (log file was empty and the error messages were still dumped on screen). Can someone please tell me how to go about logging all the messages generated during compilation/make into a logfile?

• How to fix error in a Mercurial changeset comment?

  - by Sly

  Is there a way to rewrite the hg commit message if the wrong information was entered? We always include our Bug ID when we commit a changeset. For instance: hg commit -m "Bug 14585: LastName field should be mandatory" But If I put the wrong bug ID, is there a way (through an extension maybe) to fix the comment once the changeset has been committed (and possibly pushed)?

• Real world examples of Rx

  - by theburningmonk

  I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

• Python: Why do some packages get installed as eggs and some as "egg folders"?

  - by cool-RR

  I maintain a few Python packages. I have a very similar setup.py file for each of them. However, when doing setup.py install, one of my packages gets installed as an egg, while the others get installed as "egg folders", i.e. folders with an extension of "egg". I couldn't figure out what is the difference between them that causes this different behavior. What can it be?

• Attach labels to items in TFS from the PowerBuilder IDE?

  - by DaveE

  We do this using the 'Advanced' button on the checkin dialog now (with Merant, nee PVCS) but the 'Advanced' button is disabled when I set TFS as my SCC provider. Is there a switch we can flip on either side to enable this? Or do we need to write some custom extension? Or can I get the TFS changeset number to associate with the change in PB? Or am I coming at doing selective builds entirely the wrong way?

• Mixed declarations and code in open source projects?

  - by Eduardo

  Why is still C99 mixed declarations and code not used in open source C projects like the Linux kernel or GNOME? I really like mixed declarations and code since it makes the code more readable and prevents hard to see bugs by restricting the scope of the variables to the narrowest possible. This is recommended by Google for C++. For example, Linux requires at least GCC 3.2 and GCC 3.1 has support for C99 mixed declarations and code

• In C#, how do I check if a type is a subtype OR the type of an object?

  - by Daniel T.

  To check if a type is a subclass of another type in C#, it's easy: typeof (SubClass).IsSubclassOf(BaseClass); // returns true However, this will fail: typeof (BaseClass).IsSubclassOf(BaseClass); // returns false Is there any way to check whether a type is either a subclass OR of the base class itself, without using an OR operator or using an extension method?

• What Patterns Should I Consider For a Html Widget Generator?

  - by DaveDev

  I'm looking to see if I can design a HtmlHelper extension method that will generate the Html for different types of widgets I want to produce. Each different type of widget implements functionality to get and prepare any data it needs to render. Can anyone suggest any patterns I could refer to for approaches to take? I know there are probably frameworks available that will do this for me, but I thought I'd give it a try anyway. Any points of advice? Thanks
