  • Can regular expressions be used to match nested patterns?

    - by Richard Dorman
    Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times. For example, can a regular expression match an opening and closing brace when there are an unknown number of open closing braces nested within the outer braces. For example: public MyMethod() { if (test) { // More { } } // More { } } // End Should match: { if (test) { // More { } } // More { } }

  • Who makes software validation? What are the steps of its?

    - by uzay95
    Fill in the X,Y,Z please. Software validation has X,Y,Z steps. Client have to provide X,Y,Z to the developer before starting to write software. When software finished, validation completes with doing X,Y,Z (sign, approval, test pictures, logs etc.). If we buy a general software like invoice management tool or SAP module which can modify/change for every customer, who should make the software validation?

  • Opening a huge .csv file with Excel Interop using C#

    - by user262102
    Hi, I have an application that write huge .csv files about the size ranging from 1 GB to 2 GB. I need to color code the file and save it as .xlsx. So I have tried using Excel Interop and it works great for small files, but when I try to open a 1.3 GB .csv file with Excel, I get an Hresult error. Any ideas as to how I could accomplish this task either with using Excel, or if there is any other way of doing it. Thanks!

  • Is it possible to gzip and upload this string to Amazon S3 without ever being written to disk?

    - by BigJoe714
    I know this is probably possible using Streams, but I wasn't sure the correct syntax. I would like to pass a string to the Save method and have it gzip the string and upload it to Amazon S3 without ever being written to disk. The current method inefficiently reads/writes to disk in between. The S3 PutObjectRequest has a constructor with InputStream input as an option. import java.io.*; import java.util.zip.GZIPOutputStream; import com.amazonaws.auth.PropertiesCredentials; import com.amazonaws.services.s3.AmazonS3; import com.amazonaws.services.s3.AmazonS3Client; import com.amazonaws.services.s3.model.PutObjectRequest; public class FileStore { public static void Save(String data) throws IOException { File file = File.createTempFile("filemaster-", ".htm"); file.deleteOnExit(); Writer writer = new OutputStreamWriter(new FileOutputStream(file)); writer.write(data); writer.flush(); writer.close(); String zippedFilename = gzipFile(file.getAbsolutePath()); File zippedFile = new File(zippedFilename); zippedFile.deleteOnExit(); AmazonS3 s3 = new AmazonS3Client(new PropertiesCredentials( new FileInputStream("AwsCredentials.properties"))); String bucketName = "mybucket"; String key = "test/" + zippedFile.getName(); s3.putObject(new PutObjectRequest(bucketName, key, zippedFile)); } public static String gzipFile(String filename) throws IOException { try { // Create the GZIP output stream String outFilename = filename + ".gz"; GZIPOutputStream out = new GZIPOutputStream(new FileOutputStream(outFilename)); // Open the input file FileInputStream in = new FileInputStream(filename); // Transfer bytes from the input file to the GZIP output stream byte[] buf = new byte[1024]; int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } in.close(); // Complete the GZIP file out.finish(); out.close(); return outFilename; } catch (IOException e) { throw e; } } }

  • code formatter for grails and Groovy?

    - by Jared
    I'm currently using a basic text editor to write my grails code. Does anyone know of a program that will automatically format code with indentation similar to indent does for C? I'd rather use a commandline program to do this but can use an IDE to format my code if that's the only option.

  • What is a best free way to make form resizeable in Delphi 7?

    - by Tofig Hasanov
    I need my form in Delphi to be resizeable, and all components and controls should stretch proportionally, along with font sizes etc. Right now in order to resize components I write a code inside "OnResize" event, and manually calculate all components' sizes and fonts. I would like to have more simple solution, which I can apply to different applications without rewriting this code for each form. I found some components on the web, but they are shareware. Can you suggest something?

    It is possible to write a generic function/procedure/select/somethingElse to cross-join a table against himself 'n' times? (yes, 'n' is a given parameter : ) How would you do it?

  • Normalization of database for timesheet tool and ensure data integrity

    - by fireeyedboy
    I'm creating a timesheet application. I have the following entities (amongst others): Company Employee = an employee associated with a company Client = a client associated with a company So far I have the following (abbreviated) database setup: Company - id - name Employee - id - companyId (FK to Company.id) - name Client - id - companyId (FK to Company.id) - name Now, I want an employee to be associated with a client, but only if that client is associated with the company the employee works for. How would you guarantee this data integrity on a database level? Or should I just depend on the application to guarantee this data integrity? I thought about creating a many to many table like this: EmployeeClient - employeeId (FK to Employee.id) - companyId \ (combined FK to Client.companyId, Client.id) - clientId / Thus, when I insert a client for an employee along with the employee's company id, the database should prevent this when the client is not associated with the employee's company id. Does this make sense? Because this still doesn't guarantee the employee is associated with the company. How do you deal with these things? UPDATE The scenario is as followed: A company has multiple employees. Employees will only be linked to one company. A company has multiple clients also. Clients will only be linked to one company. (Company is a sandbox, so to speak). An employee of a company can be linked to a client of it's company, but only if the client is part of the company's clientele. In other words: The application will allow a company to create/add employees and create/add clients (hence the companyId FK in the Employee and Client tables). Next, the company will be allowed to assign certain clients to certain of it's employees (EmployeeClient table). Imagine an employee working on projects for a few clients for which s/he can write billable hours, but the employee must not be allowed to write billable hours for clients they are not assigned to by their employer (the company). So, employees will not automatically have access to all their company's clients, but only to those that the company has selected for them. Hopefully this has shed some more light on the matter.

  • Is there an easy way to compare if 2 XDocuments are equal ignoring element/attribute order?

    - by Davy8
    Unit testing my serialization code I found one failed because I had attributes listed in a different order (I'm just comparing the XDocument.ToString() values) and while I could fix that, it really doesn't matter to me in what order the elements or attributes appear as long as they're all there with the right name at the right level of hierarchy. I could probably write a method do this, but I'm wondering if there's an easy built in way I'm not aware of.

  • Does mprotect flush the instruction cache on ARM Linux?

    - by Adam Goode
    I am writing a JIT on ARM Linux that executes an instruction set that contains self-modifying code. The instruction set does not have any cache flush instructions (similar to x86 in that respect). If I write out some code to a page and then call mprotect on that page, is that sufficient to invalidate the instruction cache? Or do I also need to use the cacheflush syscall on those pages?
