• EmptyDataTemplate and EmptyDataText not working

  - by Farinha

  I can't seem to get either EmptyDataTemplate or EmptyDataText of a GridView to work. I'm fetching the GridView contents in de codebehind and attaching them with using DataBind(). I've tried having them as null and as an empty List, and in both cases the text I put into EmptyDataTemplate or EmptyDataText is not displayed. What am I doing wrong?

• 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?

• Are weekly reports necessary?

  - by Dbger

  At the times that we didn't use Scrum, we had weekly status meeting and technical discussion; And now after we adopt Scrum, we have daily stand up meeting.

What do you think of weekly report? what benefit that you got from it if your like it?

• Reopening serial port fails if not closed properly with CloseHandle

  - by superg

  I am working with USB device on Windows that is seen as a virtual serial port. I can communicate with the device using CreateFile and ReadFile functions, but in some cases my application does not call CloseHandle (when my application in development crashes). After that all calls to CreateFile fail (ERROR_ACCESS_DENIED), and the only solution is to log in to my computer again. Is there any way to force closing the open handle (or reopening) programmatically?

• Are regexes really maintainable?

  - by Rich Bradshaw

  Any code I've seen that uses Regexes tends to use them as a black box: Put in string Magic Regex Get out string This doesn't seem a particularly good idea to use in production code, as even a small change can often result in a completely different regex. Apart from cases where the standard is permanent and unchanging, are regexes the way to do things, or is it better to try different methods?

• Does running a SQL Server 2005 database in compatibility level 80 have a negative impact on performa

  - by Templar

  Our software must be able to run on SQL Server 2000 and 2005. To simplify development, we're running our SQL Server 2005 databases in compatibility level 80. However, database performance seems slower on SQL 2005 than on SQL 2000 in some cases (we have not confirmed this using benchmarks yet). Would upgrading the compatibility level to 90 improve performance on the SQL 2005 servers?

• Delayed instantiation with c# using statment

  - by fearofawhackplanet

  Is there any way to write a using statement without instantiating the IDisposable immediately? For example, if I needed to do something like: using (MyThing thing) { if (_config == null) { thing = new MyThing(); } else { thing = new MyThing(_config); } // do some stuff } // end of 'using' Is there an accepted pattern for cases like this? Or am I back to handling the IDisposable explicitly again?

• What is the display list in Flash 10? Array? Linked list?

  - by Typeoneerror

  I'm working on a game that has many elements on stage, so I'm looking to optimize my loops. I know that Vector is faster than looping an array, but I'm also in some cases using: while (i < numChildren) getChildAt(i) ...to update sprites. My question is when I use getChildAt, is that accessing an Array or Vector or linked list or other? Should I instead store references to my objects in a Vector and loop through that instead?

• javascript replace i into I

  - by Eric Sim

  I need a javascript to replace i into I. This should apply to cases such as i'm good. So am i. He though i love him. The standard ThisContent = ThisContent.replace("i", "I"); doesn't work because it replaces every i. I also thought of ThisContent = ThisContent.replace(" i ", " I "); but it doesn't work for the first and second case. Any idea?

• Need Help With Simple Regex

  - by npinti

  I have strings of this type: text (more text) What I would like to do is to have a regular expression that extracts the "more text" segment of the string, so far I have been using this regular expression: "^.*\\((.*)\\)$" Which although it works on many cases, it seems to fail if I have something of the sort: text (more text (even more text)) What I get is: even more text) What I would like to get instead is: more text (even more text) (basically the content of the outermost pair of brackets.) Thanks

• SeFocus causing Run time error

  - by code8230

  I am getting: Run-time error '5': Invalid procedure call or argument this seems to happen when Text(1).SetFocus is called. However, I dont see this run time error for all the cases where I have used SetFocus. Just 2-3 places it is causing this error. Text(1).SelStart = 3 Text(1).SelLength = 1 Text(1).SetFocus I tried: Text(1).Enabled = True Text(1).Visible = True just above .SelStart, but it didn't fix the issue.

• Matlab regex if statement

Whats the best way to do this?

• UnicodeDecodeError when redirecting to file

  - by zedoo

  Hi, I run this snippet twice, in the ubuntu terminal, (encoding set to utf-8) once with ./test.py and then with ./test.py >out.txt: uni = u"\u001A\u0BC3\u1451\U0001D10C" print uni Without redirection it prints garbage. With redirection I get a UnicodeDecodeError. Can someone explain why I get the error only in the second case, or even better give a detailed explanation of what's going on behind the curtain in both cases?

• mathing string in python

  - by nani

  Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions forthe remaining problems, we are going to explore other substring matching ideas. These problems can be solved with either an iterative function or a recursive one. You are welcome to use either approach, though you may find iterative approaches more intuitive in these cases of matching linear structures

• IBOutlet on properties and exposition of the class

  - by Espuz

  Apple, for memory management issues, recommend defining outlets on properties, not in the attribute declaration. But, as far as I know, declaring properties exposes the class to external classes, so this could be dangerous. On UIViewController we have the main view definition and the logic, so MVC is slightly cheated in this cases. What is the beteer approach, Apples's recommendation for memory-management or armored classes?

• How to handle null return from custom HttpHandler in asp.net?

  - by Campos

  I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great. However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown. But since the HttpHandler is not synchronous, all my attempts checking for image size at Page_Load were frustrated. Any ideas on how this can be accomplished?

• Is there any way to identify a unique user in Flash/Actionscript 3?

  - by VGambit

  I'm trying to make a vote/poll application in Flash using Actionscript 3. Is there any way to generate a specific ID that is unique to each user? The only other option I can think of is using the IP address, which is less than ideal in many cases (college campuses, shared Internet access, etc.). It needs to be the same number every time it is run on the same PC, but different for each user.

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

• Common Template Library

  - by user1257547

  I'm trying to create a view that only houses reusable HTML blocks that can be used by other views. Wanted to know if something like this is possible: In views.home.common.scala.html: @component1 = { some common html } @component2 = { some other stuff } In views.home.sample.scala.html: @(user:User) import home._ @component1 @common.component2 Haven't had any luck thus far and I don't see anything similar in the samples but the idea is covered in the Template common use cases.

• jquery radio button group problem

  - by user198937

  Hi, I have a radio group which is validated for required. It works fine except when in certain cases I need to disabled first radio button leaving user to select one from remaining. Even in this case radios are validated but error message is not displayed. I believe its due to error message's association with first radio. Disabling other radio except first works fine too. Is there way around?
