    - by Sanctus2099
    I know it's a simple question but I really can't find anything on Google. Sorry if I'm not searching right. I created 2 pages and in the first one I have a button. What should I write in the C# code to change to redirect me on the second page? I usually know my way around C# but I'm totally new in ASP.

  • 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?

  • ANTLR expressions rewrite intermediate tree

    - by user313856
    For expressions like 3+4 I would like to use the value 7 in an intermediate representation tree. I cannot work out how to get the returns value into a rewrite rule. expression returns [int v]: etc. How do I get expression.v into WR? At the moment I get (+ 3 4), I want (7) |^( WRITE c=expression) - ^(WRINT ^(INTC ^($c)) the next step is to emit 7 in an assembler.

  • How to get multiple counts with one SQL query?

    - by Crobzilla
    I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

  • How can I determine a file extension given a file name in LaTeX?

    - by Frank
    I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  • How to pick random (small) data samples using Map/Reduce?

    - by Andrei Savu
    I want to write a map/reduce job to select a number of random samples from a large dataset based on a row level condition. I want to minimize the number of intermediate keys. Pseudocode: for each row if row matches condition put the row.id in the bucket if the bucket is not already large enough Have you done something like this? Is there any well known algorithm? A sample containing sequential rows is also good enough. Thanks.

  • MySQL Single Query Benchmarking Strategies

    - by Pepper
    Hello, I have a slow mySQL query in my application that I need to re-write. The problem is, it's only slow on my production server and only when it's not cached. The first time I run it, it will take 12 seconds, then anytime after that it'll be 500 milliseconds. Is there an easy way to test this query without it hitting the query cache so I can see the results of my refactoring? Thanks!

  • Remove leading zero's from alphanumeic text

    - by cedar715
    I've seen questions to prefix zeros here in SO. But not the other way !! Can you guys suggest me how to remove the leading zeros in alphanumeric text. Are there any built-in APIs or do I need to write a method to trim the leading zero's? Example: 01234 converts to 1234 0001234a converts to 1234a 001234-a converts to 1234-a 101234 remains as 101234 2509398 remains as 2509398 123z remains as 123z 000002829839 converts to 2829839

  • Easy way to keep counting up infinitely

    - by Andrew Alexander
    What's a good way to keep counting up infinitely? I'm trying to write a condition that will keep going until there's no value in a database, so it's going to iterate from 0, up to theoretically infinity (inside a try block, of course). How would I count upwards infinitely? Or should I use something else? I am looking for something similar to i++ in other languages, where it keeps iterating until failure.

  • [C++] Real time plotting/data logging

    - by Paul
    I'm going to write a program that plots data from a sensor connected to the computer. The sensor value is going to be plotted as a function of the time (sensor value on the y-axis, time on the x-axis). I want to be able to add new values to the plot in real time. What would be best to do this with in C++? Edit: And by the way, the program will be running on a Linux machine

  • Is there a way that I can force mod_perl to re-use buffer memory?

    - by Pavel Georgiev
    Hi, I have a Perl script running in mod_perl that needs to write a large amount of data to the client, possibly over a long period. The behavior that I observe is that once I print and flush something, the buffer memory is not reclaimed even though I rflush (I know this can't be reclaimed back by the OS). Is that how mod_perl operates and is there a way that I can force it to periodically free the buffer memory, so that I can use that for new buffers instead of taking more from the OS?

  • sql query returns incorrect result

    - by reza saberi
    I have a mysql database that stores quotation documents with some products that are clearly defining the price of each product in them, and a table for contracts storing contract details as well as customer code and quotation code to which it belongs. I have the following query to see how much is the total price of the quotation to write it in the invoice: select sum(sqproducts.price * sqproducts.quantity) as 'total-price', squotations.currency as 'currency' from sqproducts, ccontracts, squotations where sqproducts.contracted=1 AND squotations.code=sqproducts.quotation_code AND sqproducts.quotation_code=ccontracts.squotation_code AND sqproducts.quotation_code='QUOT/2012/1' group by currency

  • How to automatically monitor and limit resource of process on Windows

    - by Nat
    On Linux, normally I use ptrace function to trace all syscall, and kill the process if the it tries to do anything harmful to my machine, such as system("shutdown -s -t 00") or so. Is there a way for me to do this on Windows? EDIT: I want to write Sandbox program to limit time and memory usage of its child that can work on both Windows and Linux, and now it can only run on Linux via ptrace

  • Designing a web service to be called by another language

    - by CollegeProgrammer
    This will sound naive (but then I am a junior programmer), but if I write a web service say in Python (standard WSDL web service), I then need to host it so it is reachable from an end point. This will give a URI for the service and then from another language, say Java or VB.NET (any), I can add a web service (this one) and then call the web service's object model, correct? Thanks
