• Obtain File size with os.path.getsize() in Python 2.7.5

  - by Ruxuan Ouyang

  I am new to python. I am trying to use os.path.getsize() to obtain the file size. However, if the file name is not in Englist, but in Chinese, Gemany, or French, etc, Python cannot recognize it and do not return the size of the file. Could you please help me with it? How can I let Python recognize the file's name and return the size of these kind of files? For example: The file's name is:?????????? ????????????? ? ????????????? ???????? ?? 2030?.doc path="C:\xxxx\xxx\xxxx\?????????? ????????????? ? ????????????? ???????? ?? 2030?.doc" I'd like to use" os.path.getsize(path) But it does not recognize the file name. Could you please kindly tell me what should I do? Thank you very much!

• Weblogic Class-Path Dependencies EAR

  - by Mo

  I am deploying an EAR in a WebLogic node with many jars defined in the bootstrap (startWeblogicServer.bat) class-path. The problem is that my ear and the bootstrap contain different versions of the same jars, not only that but certain jars contain extracted third party libraries which also differ in version from the WebLogic bootstrap jars causing all kinds of classpath errors. I know you can set preferred jars in the EAR application xml but, this can be very tedious to resolve with regards to jars which include extracted third party libraries in terms of understanding all the dependencies.. Is there a correct approach that i need to be taking here? Am i thinking about this in the wrong way? Any help would be greatly appreciated! So far prefer-web-inf-classes has been recommended but wont work because i'm not deploying a WAR, also prefer-application-packages is what we are currently using but still has the issue described above... Anymore advice out there?? Thanks!

• "Access is denied" when copying text file to printer UNC path

  - by Patrick

  We have a new server running Server 2008 R2. We also have a "DOS-based" program that prints directly to the UNC path of a print share. With the new server, we are unable to print from this program. According to support, the program's printing works in the same way as if we were to do a "copy mytextfile.txt \\myserver\myprinter". When we try to run this command in DOS, we get "Access is denied". Support is saying that this is why the DOS program is not able to print. I have tried granting all permissions on the printer to the appropriate users (under Security of the printer properties) but that did not work. Is there a policy setting that would cause this to be denied?

• Meta package / quick reference for command line string manipulation tools?

  - by Dylan McCall

  The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

• IOException reading a large file from a UNC path into a byte array using .NET

  - by Matt

  I am using the following code to attempt to read a large file (280Mb) into a byte array from a UNC path public void ReadWholeArray(string fileName, byte[] data) { int offset = 0; int remaining = data.Length; log.Debug("ReadWholeArray"); FileStream stream = new FileStream(fileName, FileMode.Open, FileAccess.Read); while (remaining > 0) { int read = stream.Read(data, offset, remaining); if (read <= 0) throw new EndOfStreamException (String.Format("End of stream reached with {0} bytes left to read", remaining)); remaining -= read; offset += read; } } This is blowing up with the following error. System.IO.IOException: Insufficient system resources exist to complete the requested If I run this using a local path it works fine, in my test case the UNC path is actually pointing to the local box. Any thoughts what is going on here ?

• How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

  - by John

  I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?

• dynamic linking:change of the linking path.

  - by benjamin button

  Normally it happens that when ever the path of the library that has to be linked dynamically is defined in LD_LIBRARY_PATH or it it will be mentioned with -L flag while creating the binary. In actual scenario if ,lets say the binary has been built and deployed at the client place. Now if there is a change in the path of one of the dynamic link library path. then we need to supply a new make file to all the clients where the binary was deployed. is there any other method where we need not tell all the clients to change their makefiles and can something can be done in the code itself? if yes...could anybody please suggest how? This was ironically an interview question that was asked to me and i didnot have the answer for it.

• Copy a file to a new directory path in DOS

  - by nodmonkey

  How can I copy a file using DOS commands into a directory structure that may not yet exist? I need to be able to force the creation of the directory path to the target file location if that location doesn't already exist. For example, there is already a file.txt in this location: C:\file.txt And I want to copy it to C:\example\new\path\to\copy\of\file\file.txt but at this time C:\example\ and all the subdirectories may or may not yet exist. Basically, I am looking for a "copy and create the target path if necessary" command. What would you recommend is the best way to achieve this?

• CALayer flickers when drawing a path

  - by Alexey

  I am using a CALayer to display a path via drawLayer:inContext delegate method, which resides in the view controller of the view that the layer belongs to. Each time the user moves their finger on the screen the path is updated and the layer is redrawn. However, the drawing doesn't keep up with the touches: there is always a slight lag in displaying the last two points of the path. It also flickers, but only while displaying the last two-three points again. If I just do the drawing in the view's drawRect, it works fine and the drawing is definitely fast enough. Does anyone know why it behaves like this? I suspect it is something to do with the layer buffering, but I couldn't find any documentation about it.

• Assign binding path at runtime in WPF DataTemplate

  - by Abiel

  I am writing a WPF program in C# in which I have a ListView for which the columns will be populated at runtime. I would like to use a custom DataTemplate for the GridViewColumn objects in the ListView. In the examples I have seen where the number of columns is fixed in advance, a custom DataTemplate is often created using something like the XAML below. <DataTemplate x:Key="someKey"> <TextBlock Text="{Binding Path=FirstName}" /> </DataTemplate> This DataTemplate could also later be assigned to GridViewColumn.CellTemplate in the code-behind by calling FindResource("someKey"). However, this alone is of no use to me, because in this example the Path element is fixed to FirstName. Really I need something where I can set the Path in code. It is my impression that something along these lines may be possible if XamlReader is used, but I'm not sure how in practice I would do this. Any solutions are greatly appreciated.

• How to find the physical path of a GSP file in a deployed grails application

  - by Deepak Mittal

  I need to find out the physical path of a grails GSP file. My requirement is that I want to create a new layout file at run-time and use that in the application. I have been able to achieve this without problem when the application runs on jetty (grails run-app), however, when I deploy the app on Jboss, the path at which the file needs to be created changes. So, ideally I would like to find out at runtime using some magical utility the path of a particular GSP (lets say main.gsp layout file) and I need to create my new layout in the same directory in which main.gsp reside. Any pointers? -Deepak

• Powershell: resolve path that might not exist?

  - by Eamon Nerbonne

  I'm trying to process a list of files that may or may not be up to date and may or may not yet exist. In doing so, I need to resolve the full path of an item, even though the item may be specified with relative paths. However, Resolve-Path prints and error when used with a non-existant file. For example, What's the simplest, cleanest way to resolve ".\newdir\newfile.txt" to "C:\Current\Working\Directory\newdir\newfile.txt" in Powershell? Note that System.IO.Path's static method use with the process's working directory - which isn't the powershell current location.

• PATH and CLASSPATH in Windows7 7 / Eclipse

  - by Richard Knop

  So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line. This is where I have Java installed: C:\Program Files (x86)\Java jdk1.6.0_20 jre6 And this is where eclipse stores my Java projects: D:\java-projects HelloWorld bin HelloWorld.class src HelloWorld.java I have set up the PATH and CLASSPATH variables like this: PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin CLASSPATH: D:\java-projects But it doesn't work. When I write: java HelloWorld Or: java HelloWorld.class I get error like this: Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld The error is longer, that's just the first line. How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.

• Importing war file into eclipse and build path problem

  - by Todd

  Hi, I am facing some weird problem when importing .war file into eclipse. The problem is, the build folder does not contain any necessary class folder. So when I try to set the build path, eclipse reports "Error while adding to build path. Reason: cannot nest output folder 'projectName/build/class' inside 'projectName/build'. From what I understand, 'build' folder is what classes get collected(as build version) right? I tried to ignore build path and just export .war file into tomcat server, but somehow servlet file keeps showing old code, which I changed in eclipse. So, I am thinking without proper build folder, exported .war will not contain modified servlect code.( I am sorry if this doesn't sound clear) What can I do to fix this problem? I already tried to create a whole new workspace and restarted eclipse several times and it didn't solve the problem.

• Parse filename from full path using regular expressions in C#

  - by WindyCityEagle

  How do I pull out the filename from a full path using regular expressions in C#? Say I have the full path C:\CoolDirectory\CoolSubdirectory\CoolFile.txt. How do I get out CoolFile.txt using the .NET flavor of regular expressions? I'm not really good with regular expressions, and my RegEx buddy and me couldn't figure this one out. Also, in the course of trying to solve this problem, I realized that I can just use System.IO.Path.GetFileName, but the fact that I couldn't figure out the regular expression is just making me unhappy and it's going to bother me until I know what the answer is.

• I need an algorithm to find the best path

  - by user242635

  I need an algorithm to find the best solution of a path finding problem. The problem can be stated as: At the starting point I can proceed along multiple different paths. At each step there are another multiple possible choices where to proceed. There are two operations possible at each step: A boundary condition that determine if a path is acceptable or not. A condition that determine if the path has reached the final destination and can be selected as the best one. At each step a number of paths can be eliminated, letting only the "good" paths to grow. I hope this sufficiently describes my problem, and also a possible brute force solution. My question is: is the brute force is the best/only solution to the problem, and I need some hint also about the best coding structure of the algorithm.

• Android HelloWorld Build Path error

• How to use a different path name in ProxyPass than the Tomcat context name

  - by Diptendu Dutta

  Hello, I am using Tomcat 5.5.9 and Apache 2.x We are trying to use a path name in ProxyPass that is different than the Tomcat context name. ProxyPass /path http://localhost:8080/contextname However, this does not work. When these two are the same then everything works fine. Most examples I see on the net also have the path equal to the Tomcat context name. I am using "context.xml" within the Tomcat context and do NOT have "server.xml" entries. Also, I am using plain httd.conf and NOT using any VirtualHost entries. Any help is appreciated. Regards, Diptenu
