  • ACCESS/VBA: How to create a ON/OFF type switch to allow record modification on a form ?

    - by Christian M
    I was using a combobox on my search form to select whether to consult or modify a record. To make it more user friendly (IMO), I put a togglebutton on a form, which controls the .AllowEdits property of my form. This way you can easily switch from reading to writing. However I run into a problem; once .AllowEdits is switched to false, the togglebutton is not clickable anymore ! What are my options ?

  • Concatenate SQL script from Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.

  • How to extract keywords from a body of text in PHP

    - by Akeem
    Currently I'm leveraging http://developer.yahoo.com/search/content/V1/termExtraction.html which isn't ideal for performance and quality reasons. Before I embark on spending time on writing a system I wanted to see if there are any other available options that can do the trick.

  • VS/C#: Can I be notified of every event that gets handled while debugging?

    - by Daniel I-S
    I am currently troubleshooting a large and unwieldy GUI-based tool in Visual Studio, and was wondering whether there is any way to get some kind of notification (either by writing to the console or through a third-party tool) whenever any handled event occurs. This would make it a lot easier to track down what precisely is going on while I am interacting with this beast. Is there an 'on any event being handled' event I can handle, or some kind of add-in for VS which would make this possible?

  • Asp.net mvc small amount data storage

    - by Trimack
    Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

  • creative way for implementing Data object with it's corespanding buisness logic class in java

    - by ekeren
    I have a class that need to be serialized (for both persistentcy and client-server communication) for simplicity reasons lets call the classes Business a BusinessData and I prefix for their Interfaces. All the getter and setter are delegated from Business class to BusinessData class. I thought about implementing IBusinessData interface that will contain all the getter and setters and IBusiness interface that will extend it. I can either make Business extend BuisnessData so I will not need to implement all getter and setter delegates, or make some abstract class ForwardingBusinessData that will only delegate getter and setters. Any of the above option I loose my hierarchy freedom, does any of you have any creative solution for this problem... I also reviewed DAO pattern: http://java.sun.com/blueprints/patterns/DAO.html

  • Can you authenticate Facebook Graph entirely from command line with Python?

    - by Sebastian
    I'm writing a (tabbed) application for Facebook that requires a background process to run on a server and, periodically, upload images to an album on this application's page. What I'm trying to do is create a script that will: a) authenticate me with the program b) upload an image to a specific album All of this entirely from the command line and completely with the new Graph API. My problem right now is trying to locate the documentation that will allow me to get a token without a pop-up window of sorts. Thoughts?

  • How to learn proper C++?

    - by Chris
    While reading a long series of really, really interesting threads, I've come to a realization: I don't think I really know C++. I know C, I know classes, I know inheritance, I know templates (& the STL) and I know exceptions. Not C++. To clarify, I've been writing "C++" for more than 5 years now. I know C, and I know that C and C++ share a common subset. What I've begun to realize, though, is that more times than not, I wind up treating C++ something vaguely like "C with classes," although I do practice RAII. I've never used Boost, and have only read up on TR1 and C++0x - I haven't used any of these features in practice. I don't use namespaces. I see a list of #defines, and I think - "Gracious, that's horrible! Very un-C++-like," only to go and mindlessly write class wrappers for the sake of it, and I wind up with large numbers (maybe a few per class) of static methods, and for some reason, that just doesn't seem right lately. The professional in me yells "just get the job done," the academic yells "you should write proper C++ when writing C++" and I feel like the point of balance is somewhere in between. I'd like to note that I don't want to program "pure" C++ just for the sake of it. I know several languages. I have a good feel for what "Pythonic" is. I know what clean and clear PHP is. Good C code I can read and write better than English. The issue is that I learned C by example, and picked up C++ as a "series of modifications" to C. And a lot of my early C++ work was creating class wrappers for C libraries. I feel like my own personal C-heavy background while learning C++ has sort of... clouded my acceptance of C++ in it's own right, as it's own language. Do the weathered C++ lags here have any advice for me? Good examples of clean, sharp C++ to learn from? What habits of C does my inner-C++ really need to break from? My goal here is not to go forth and trumpet "good" C++ paradigm from rooftops for the sake of it. C and C++ are two different languages, and I want to start treating them that way. How? Where to start? Thanks in advance! Cheers, -Chris

  • How to write mod_security friendly PHP code?

    - by KPL
    Hello people, I made a theme in WordPress which hit the mod_security rule on HostGator and gave 403 error. I contacted people there(at HostGator) and they fixed it for me. But I don't want my theme to work like this. I just wanted to know if there are any guides/blog post/tutorials telling about writing PHP code which is mod_security friendly? I tried Google, but didn't find anything helpful.

  • mounting ext4 fs with block size of 65536

    - by seaquest
    I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I can not mount it on ubuntu-10.10-netbook-i386.

  • Assembly Programming and Interrupt Handling

    - by nmr
    I'm writing a program in assembly using MIPS architecture for a class, and I'm having trouble figuring out how to grab an input character by a user and store it in a register to process. The program would open a console, output a message, the user can then input a character and then this determines what is supposed to happen next in the program. Like I said, I'm having trouble figuring out how to grab the character so that I can act upon it in the program. thanks
