  • Using a filename with spaces with scp and chmod in bash.

    - by speciousfool
    Periodically, I like to put files in the /tmp directory of my webserver to share out. What is annoying is that I must set the permissions whenever I scp the files. Following the advice from another question I've written a script which copies the file over, sets the permissions and then prints the URL: #!/bin/bash scp "$1" SERVER:"/var/www/tmp/$1" ssh SERVER chmod 644 "/var/www/tmp/$1" echo "URL is: http://SERVER/tmp/$1" When I replace SERVER with my actual host, everything works as expected...until I execute the script with an argument including spaces. Although I suspect the solution might be to use $@ I've not yet figured out how to get a spaced filename to work.

  • Visual Studio: Design a UserControl class that derives from an abstract base class

    - by Marcel
    Hi All, I want to have an abstract base class for some of my custom UserControl's. The reason is obvious: they share some common properties and methods (a basic implementation of some elements of an interface actually), and I want to implement them only once. I have done this by defining my abstract base class: public abstract class ViewBase : UserControl, ISomeInterface Then I went to implement one of my views, as usual, with the designer: public partial class SpecialView : UserControl //all OK Up to here all is fine. Now I replace the derivation of my SpecialView class with the abstract base class: public partial class SpecialView : ViewBase //disrupts the designer Now, the designer in Visual Studio 2008 won't work anymore, stating: The designer must create an instance of type 'ViewBase' but it cannot because the type is declared as abstract. How can I circumvent this? I just do not want to have the same code copied for all those views. Info: there is a question question with virtual methods, instead of abstract classes, but there is no suitable solution for me.

  • How to write outline data into .otf files?

    - by Sorush Rabiee
    I need to edit or completely replace outline data (bezier curves) of OpenType fonts. the input data is an EPS file that i have to write it into one specified glyph of an otf file with a certain scaling. (The glyph is specified by PostScript name OR Unicode value.) I need something like an encoder (or just a library of file structure of OpenType)? where to find about structure of otf and ttf files? Note: python-realated tools and libraries are performed :-?

  • Changing system colors for a single application (Windows, .NET)

    - by Michal Czardybon
    I know I should generally avoid messing up with such system settings, but my application do already use nonstandard colors and I have no influence on that. I would like to be able to add standard .NET controls in some places, but their colors do not match. I would like to have a hack that would replace system colors for this one application. One more important thing to note is that it is a .NET application. My (incomplete) ideas so far were: To create a proxy User32.dll library with replaced GetSysColor, but it would be very tedious (731 functions to be redirected, 1 to be replaced) and I do not know how to force my application to use that particular copy. To intercept somehow invocations to GetSysColors (unfortunatelly it is somewhere in the CLR I think). To modify somehow .NET class SystemColors (in memory? is it possible?). Do you have any idea, what is the best (and complete) way to achieve this?

  • putenv/setenv using substitutions

    - by vinaym
    I need user to define all the environment variables needed for my program in a text file as shown below. MyDLLPath = C:\MyDLLPath MyOption = Option1 PATH = %MyDLLPath%;%PATH%; In my program I read each line and call putenv with the string. Problem is that the environment substitutions (%MyDLLPath%) are not being expanded. I am guessing the following fix for that 1. Check each line for % characters. 2. Get the text between 2 consecutive % characters. 3. Call getenv using the text from step 2. 4. Replace value obtained above into the line and then call putenv. Is there a better way to do it?

  • Basic refactoring features (e.g., Rename) unavailable when editing code in an aspx/ascx files

    - by DanM
    I was just editing some C# code between <% %> tags in an .ascx file, and I noticed that the Refactor contextual menu is unavailable. And even if I manually add items from this menu to a custom toolbar, they are disabled when viewing aspx/ascx files. I usually only have small snippets of C# code in my aspx/ascx files, but it would still be nice to be able to perform refactoring operations on any code that exists between <% %> tags. I feel like I'm going back to the dark ages when I have to use find/replace to change the name of a variable. Questions Is there a way to enable Visual Studio's refactoring features while viewing aspx/ascx files in Visual Studio? Are there any Visual Studio plug-ins (preferably free) that offer this kind of functionality?

  • Confusion regarding laziness

    - by Abhinav Kaushik
    I have a function myLength = foldl (\ x _ -> x + 1) 0 which fails with stack overflow with input around 10^6 elements (myLength [1..1000000] fails). I believe that is due to the thunk build up since when I replace foldl with foldl', it works. So far so good. But now I have another function to reverse a list : myReverse = foldl (\ acc x -> x : acc) [] which uses the lazy version foldl (instead of foldl') When I do myLength . myReverse $ [1.1000000]. This time it works fine. I fail to understand why foldl works for the later case and not for former?

  • SSMS Results to Grid - CRLF not preserved in copy/paste - any better techniques?

    - by Cade Roux
    When I have a result set in the grid like: SELECT 'line 1 line 2 line 3' or SELECT 'line 1' + CHAR(13) + CHAR(10) + 'line 2' + CHAR(13) + CHAR(10) + 'line 3' With embedded CRLF, the display in the grid appears to replace them with spaces (I guess so that they will display all the data). The problem is that if I am code-generating a script, I cannot simply cut and paste this. I have to convert the code to open a cursor and print the relevant columns so that I can copy and paste them from the text results. Is there any simpler workaround to preserve the CRLF in a copy/paste operation from the results grid? The reason that the grid is helpful is that I am currently generating a number of scripts for the same object in different columns - a bcp out in one column, an xml format file in another, a table create script in another, etc...

  • Run groovy script from within gradle

    - by macattack
    What's the best way to create a gradle task, which runs a groovy script? I realize that gradle build files are groovy, so I would think it would be possible to do something like this: task run << { Script app = new GroovyShell().parse(new File("examples/foo.groovy")) // or replace .parse() w/ a .evalulate()? app.run() } I get all kinds of whacky errors when I try this if bar.groovy is using @Grab annotations or even doing simple imports. I want to create a gradle task to handle this, so that I can hopefully reuse the classpath definition. Would it be better to move the examples directory into the src directory somewhere? What's a best practice?

  • DataAnnotations in ASP.NET MVC 2 - Stop MVC from applying RequiredAttribute to Non-nullable DateTime

    - by jwwishart
    Im trying to create a custom version of the RequiredAttribute to replace the built in one and I've got it working for properties that have strings values, but with properties that are DateTime or integer for example, the default RequiredAttribute seems to be applied automatically (IF the property is not nullable!) My problem is that i want to be able to specify a DateTime property as required using my custom required validator which gets the error message from a resources file (I don't want to have to tell the RequiredAttribute the type of the resource file and the key every time i apply it. That is why I'm making a custom one.) How can i prevent the framework from applying the required attribute to properties of type DateTime and int etc without changing them to nullable. Thanks

  • VS2010 patce: why it's take so muce time to install it?

    - by Mendy
    Visual Studio 2010 RC has a few of patches release. For more information about them take a look here. What I'm expect from patch program, is to replace a few dll's of the program to a new fixed version of them. But when I run each of this 3 patches, they take a lot of time (5 minutes each), and you think that the program was frozen because the progress bar stay on the begging. This is question may not be so important, but it really interesting me to know, why this happens? It's really confusing to see that each VS2010 (or Microsoft in general) is frozen to 4-5 minutes.

  • Rails: translations for table's column.

    - by Andrew
    In rails application I have two models: Food and Drink. Both food and drink have a name, which has to be stored in two languages. How do I better realize translations for theese tables? First solution I realized was to replace name column with name_en and name_ru. Another solution is to encode with YAML hash like { :en => 'eng', :ru => 'rus' } and store yaml as a name. What would you recommend, assuming content is not static? Maybe there's good article?

  • MOSS 2007 - Using Connectable WebPart - Consumer has TextBox

    - by JohnP
    I have 2 webparts which are connected, where the provider sends a string to the consumer. However it fails to work if I put any TextBox controls in the consumer webpart. (works fine if I use a Label or Literal control. The idea is that the consumer is to be composed of form controls like TextBoxes. e.g. the codeproject sample at http://www.codeproject.com/KB/sharepoint/ConnectingCustomWebParts.aspx Works fine... until you replace the consumer Label control with a TextBox. Any help gratefully received.

  • Security exception with ASP.NET AJAX toolkit

    - by Rod
    I've got an ASP.NET WebForms app that I've written, which uses the ASP.NET AJAX Toolkit. I've put the MultiView control onto the web form, and it worked fine, when I had it under Vista. Well, I had to replace my machine (HD failed) and I went to Windows 7 Ultimate. I tried copying the ASP.NET app from the system (before it finally failed for good) and put it onto the Windows 7 machine. I can bring up the app fine, go to all pages, but the one with these controls on it. When I do I get the following error: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. What's going on? How do I fix it?

  • create table based on a user defined type

    - by Glen
    Suppose I have a user defined type: CREATE OR REPLACE TYPE TEST_TYPE AS OBJECT ( f1 varchar2(10), f2 number(5) ); Now, I want to create a table to hold these types. I can do the following: create table test_type_table ( test_type_field test_type ); This gives me a table with one column, test_type_field. Is there an easy and automated way to instead create a table such that it has 2 columns, f1 and f2?. So that it's the equivilent to writing: create table test_type_table ( f1 varchar2(10), f2 number(5) );

  • Wrapping \NewEnviron into \newenvironment fails

    - by o_O Tync
    Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{aaa(\BODY)bbb} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

  • Should I use multiple ListViews?

    - by janfsd
    Hi to everybody! I have a RelativeLayout with different elements. I was planning to have two ListViews on it, but I have noticed there are some problems with scrolling. Since each ListView only shows a maximum of 5 rows should I try to make some kind of custom adapter to merge those ListViews? Or is it better to replace the ListView with a LinearLayout/RelativeLayout and add the rows as I get them manually? (like the first answer in here: http://stackoverflow.com/questions/1778485/android-listview-display-all-available-items-without-scroll-with-static-header ). Which should be the proper way on doing this? or is there another way? Also, each row will have an OnClickListener.

  • Reducing Code Repetition: Calling functions with slightly different signatures

    - by Brian
    Suppose I have two functions which look like this: public static void myFunction1(int a, int b, int c, string d) { //dostuff someoneelsesfunction(c,d); //dostuff2 } public static void myFunction2(int a, int b, int c, Stream d) { //dostuff someoneelsesfunction(c,d); //dostuff2 } What would be a good way to avoid repeated dostuff? Ideas I've thought of, but don't like: I could make d an object and cast at runtype based on type, but this strikes me as not being ideal; it removes a type check which was previously happening at compile time. I could also write a private helper class that takes an object and write both signatures as public functions. I could replace dostuff and dostuff2 with delegates or function calls or something.

  • Matrix multiplication in java (RE-POST)

    - by Chapax
    Apologies for the re-post; the earlier time I'd posted I did not have all the details. My colleague, who quit the firm was a C# programmer, was forced to write Java code that involved (large, dense) matrix multiplication. He's coded his own DataTable class in Java, in order to be able to a) create indexes to sort and join with other DataTables b) do matrix multiplication. The code in its current form is NOT maintainable/extensible. I want to clean up the code, and thought using something like R within Java will help me focus on business logic rather than sorting, joining, matrix multiplication, etc. Plus, I'm very new to the concept of DataTable; I just want to replace the DataTable with 2D arrays, and let R handle the rest. (I currently do not know how to join 2 large datasets in java very efficiently Please let me know what you think. Also, are there any simple examples that I can take a look at?

  • Why does sorl.thumbnail ImageField fail in the admin?

    - by Mark0978
    I have code that looks like this: from sorl.thumbnail import ImageField class Gallery(models.Model): pass class GalleryImage(models.Model): image = ImageField(upload_to='galleries') In the admin: class GalleryImageInline(admin.TabularInline): model = GalleryImage class GalleryAdmin(admin.ModelAdmin): inlines = (GalleryImageInline,) If I use the sorl.thumbnail as above, it is impossible to add images in the admin. I get the validation error Enter a list of values. If I replace the sorl.thumbnail.ImageField with a plain django ImageField, everything works. If I want sorl.thumbnail to clean up the cache thumbnails, I need to use it in the model, but if I use it in the model, I can't seem to add any images to need thumbnails. Anyone else found and fixed this problem yet?

  • As our favorite imperative languages gain functional constructs, should loops be considered a code s

    - by Michael Buen
    In allusion to Dare Obasanjo's impressions on Map, Reduce, Filter (Functional Programming in C# 3.0: How Map/Reduce/Filter can Rock your World) "With these three building blocks, you could replace the majority of the procedural for loops in your application with a single line of code. C# 3.0 doesn't just stop there." Should we increasingly use them instead of loops? And should be having loops(instead of those three building blocks of data manipulation) be one of the metrics for coding horrors on code reviews? And why? [NOTE] I'm not advocating fully functional programming on those codes that could be simply translated to loops(e.g. tail recursions) Asking for politer term. Considering that the phrase "code smell" is not so diplomatic, I posted another question http://stackoverflow.com/questions/432492/whats-the-politer-word-for-code-smell about the right word for "code smell", er.. utterly bad code. Should that phrase have a place in our programming parlance?
