  • Why use constants in programming?

    - by Adam N
    I've just been going back over a bit of C studying using Ivor Horton's Beginning C book. I got to the bit about declaring constants which seems to get mixed up with variables in the same sentence. Just to clarify, what is the difference in specifying constants and variables in C, and really, when do you need to use a constant instead of a variable? I know folks say to use a constant when the information doesn't change during program execution but I can't really think of a time when a variable couldn't be used instead. Thanks

  • Log Shipped but Won't Update

    - by MooCow
    I'm currently taking the MS SQL 2K5 Admin course at a local college and ran into a problem with the Log Shipping part. My setup is the following: Windows 7 x64 SQL 2005 SP3 2 SQL server instances on the same machine Log Shipping settings: Performed full then log back up of Primary Manually restore on Secondary in STANDBY MODE Insert a new record into the table Set up Log Shipping on Primary using SQL Authenication login to connect to the Secondary Set up timers and copy destination on Secondary Monitoring instance not being used I set up a shared folder for WORKGROUP so both instances on the machine can read & write to it. I can see transaction logs generated and copied as defined by the Transaction Shipping wizard. However, the specified table on the Secondary instance is not updating.

  • int[] to string c#

    - by Robin Webdev
    Hi I'm developing an client application in C# and the server is written in c++ the server uses: inline void StrToInts(int *pInts, int Num, const char *pStr) { int Index = 0; while(Num) { char aBuf[4] = {0,0,0,0}; for(int c = 0; c < 4 && pStr[Index]; c++, Index++) aBuf[c] = pStr[Index]; *pInts = ((aBuf[0]+128)<<24)|((aBuf[1]+128)<<16)|((aBuf[2]+128)<<8)|(aBuf[3]+128); pInts++; Num--; } // null terminate pInts[-1] &= 0xffffff00; } to convert an string to int[] in my c# client i recieve: int[4] { -14240, -12938, -16988, -8832 } How do I convert the array back to an string? I don't want to use unsafe code (e.g. pointers) Any of my tries resulted in unreadable strings.

  • EGL initialized failed

    - by aquatear
    Hello Everybody, I used a SurfaceView and EGL to render my 3D contents. When I press BACK and return my activity, the activity's 3D objects become to white. The reason is when the original activity(3D activity) resume, EGL would initialize again. So EGL would initialize and destroy everytime when different activities switch. I am not sure if the problem is EGL initialize twice... but I did initialize and destroy EGL correctly. Anybody have this problem ? Have any solutions about this ?? Thank you so much

  • BlackBerry responseXML is null

    - by Andrew
    I'm trying to port a portion of AJAX code I wrote over to the BlackBerry application's embedded browser. Our base build is 4.6.1 and the RIM documentation claims that XMLHttpRequest's responseXML is available starting with this version. And when I request an XML file from my local server, I get back the responseText (so I know the request is working), but the responseXML is always null. I've made sure the HTTP "Content-Type" header is set to "text/xml" and I am getting the correct data loaded in a web browser. It's just nulling out in the BB web environment. Does anyone know what might be happening? A backup of using the responseText and piping it through DOMParser is not possible because that object was not added to the BB browser until 4.7.1. So I'm not sure what fallback I have.

  • How to Return A File and a strongly Typed data at the same time?

    - by chobo2
    Hi I am using asp.net mvc 1.0 and I want to return a XML file but I also want to return a strongly typed data back so I can update some fields. Like the XML file will contain users who failed to be inserted into the database. So I want that to appear as a dialog save box what asp.net mvc return file() would do. However I also want to return on the page like values like how many users failed to be added, how many users where added, etc. So I want to use scafolding with the class file I want to pass it along. If this was a view I could pass it along as an object model but I don't see a parameter for that in File(). I also don't want to save the xml file onto the harddrive I want to do it through memory. So have a link that would display on the page to download the file and show the the data I want would not be desired.

  • How can you get the first digit in an int (C#)?

    - by Dinah
    In C#, what's the best way to get the 1st digit in an int? The method I came up with is to turn the int into a string, find the 1st char of the string, then turn it back to an int. int start = Convert.ToInt32(curr.ToString().Substring(0, 1)); While this does the job, it feels like there is probably a good, simple, math-based solution to such a problem. String manipulation feels clunky. Edit: irrespective of speed differences, mystring[0] instead of Substring() is still just string manipulation

  • Drupal CCK Text field not saving.

    - by Mark Milbourne
    Hey Guys, I've been trying to write a CCK Field based on the Text field. But if I create a standard CCK Text field with only 1 value. Then edit a content item for this type, the values are never persisted. When I go back in and edit the same node, the value isn't there. I checked the database and its not in the table for the CCK node. If I use more than one value it works fine. I'm upto date on CCK (6.x-2.6) and CTools (6.x-1.5). Has anyone seen this? and a possible solution?

  • How to see contents of deployed datasource?

    - by callisto
    I've inherited a project (without a handy handover) that contains reports published to a Reporting Server (2005). MY SSRS knowledge is 4 years stale, so I need your help. I need to edit one of the published reports, is this possible? I also want to peek into the Data Source on the RS, coz that's probably where I can change stuff. I'll add more info as I get a better understanding of what exactly to ask. EDIT: I found a project for some of the reports, opened up in VS2005 BI. Still, how do see where the Data Source gets its data? It brins back 56 fields but I dont know which tables/stored procs/queries are used to get these.

  • MSMQ empty object on message body

    - by Owen
    Ok, so I'm very VERY new to MSMQ and I'm already confused. I have created a private queue and added a few messages to it, all good so far. BUT when I retrieve the messages back from the queue the message body contains a empty object of the type I added. By this I don't mean that the body is null, it does have a reference to a type of the object that I added, but it's not instantiated so all the properties are in their null or default state. This is the code I use to add to the queue: using (var mQueue = new MessageQueue(QueueName)) { var msg = new Message(observation) { Priority = MessagePriority.Normal, UseJournalQueue = true, AcknowledgeType = AcknowledgeTypes.FullReceive, }; mQueue.Send(msg); } And this is the code that dequeues the messages: using (var mQueue = new MessageQueue(QueueName)) { mQueue.MessageReadPropertyFilter.SetAll(); ((XmlMessageFormatter)mQueue.Formatter).TargetTypes = new[] { typeof(Observation) }; var msg = mQueue.Receive(new TimeSpan(0, 0, 5)); var observation = (Observation)msg.Body; return observation; }

  • Using nsIZipWriter or other to compress a string as a string?

    - by Daniel
    I need to be able to take a javascript string, compress it using any fast and available means and get back a binary string/blob. Background: The extension I'm developing needs to send various large content to my server. It does this conveniently by dynamically creating a form, adding fields to the form and posting it. Some of these fields are just too big bandwidth wise for multiple use. I'd like to be able to compress them before adding them and then maybe base64'ing them if the characters cause a problem in the message. Any ideas? I could use nsiZipWriter with temporary files on disk but that is quite ugly and probably sluggish.

  • Making an asynchronous interface appear synchronous to mod_python users

    - by Trey
    I have a Python-driven web interface powered by Apache 2.2 with mod_python and Python 2.4. I need to make an asynchronous process appear synchronous to users of this web interface. When users access one module on this website: An external SOAP interface will be contacted with a unique identifier and will respond with a number N The external interface will respond asynchronously by contacting a SOAP server on my machine between 1 and 10 times (the number N tells us how many responses we will receive) I need to somehow aggregate these responses and pass them to the original module which will display the information back to the user. The goal is to make the process appear synchronous to the user. What is the best way to handle this synchronization issue? Is this something Twisted would be well-suited for? I am not restricting myself to Python for the solution, though it is preferred because everything else on the server is in Python. I prefer a solution that is both scalable and will take a minimal amount of programming time (though I understand that these attributes are somewhat at odds).

  • What is a good format for command line output when it is being used for further processing?

    - by Mick
    I have written a console application in Delphi that queries information from several locations. This application will be launched by another process, and the output to STDOUT will be captured by the launching process. The information I am retrieving is to be interpreted by the calling application for reporting purposes. What is the best way to output this data to STDOUT so that it can be easily parsed? JSON? XML? CSV? The data, specifically, is remote workstation information, so it will pull things back like running processes, and details about each process. Does anyone have any experience with this or suggestions?

  • Install the proper bitness Visual C++ Runtime Library via a Setup project

    - by chiru_valentin
    Hi all! The context: I have a solution that contains amongh other C# projects, a VC++ project that suports compiling only as x64 or Win32 (but not Any CPU). In order for the application (which in fact is a macro for a third party application) to run, it requires Visual C++ Runtime libraries (x86) or (x64) (The macro will run on both x64 and x86 operating systems.) The problem: I want to create a Visual Studio setup project that would install the macro on both x86 and x64 operating systems, and the problem I have is to specify what Visual C++ Runtime library to use a prerequisite. If both are selected (x64 and x86) than I have a runtime error message when running the setup.exe, as on x86 operating systems you cannot run x64 executables like the Visual C++ Runtime libraries (x64) kit is...(which the setup calls in the back). So I would need a bitness condition, or something like that to tell the setup what bitness version of the Visual C++ Runtime library to try to install...I'm not sure if this is possible, or even where such a code should be placed in the setup. Thank you for the support, Vali

  • Is 'donation' considered as commerical?

    - by Horace Ho
    I want to port an open source program to iPhone, the license prohibited any commercial use of the code. I emailed the author and he sent back an email saying freeware is ok. Of course I cannot (should not) charge anything on top of the code. Still, I want to get compensation for my work on UI design, graphics and integration work. So I wonder: Is donation (via PayPal) OK for my case? Is in-app purchase OK? i.e. the program is free, the user has the option to buy addition theme graphics? Thanks

  • Do you leave Windows Automatic Updates enabled on your production IIS server?

    - by Nobody
    If you were running a 24/7 website on Windows Server 2003 (IIS6). Would you leave the Windows automatic update feature enabled or would you turn it off? When enabled, you always get the latest security patches and bug fixes automatically as soon as they're available, which is the most secure choice. However, the machine will sometimes get automatically rebooted to apply the updates leading to a couple of minutes of downtime in the middle of the night. Also, I've seen rare occasions where the machine does not restart correctly resulting in further downtime. If auto updates are off, when do you apply the patches? I guess you have to use a load balancer with multiple web servers and rotate them out of the production site, apply patches manually, and put them back in. This can be logistically inconvenient when the load balancer is managed by a hosting company. You will also have machines in production that don't always have the latest security patches and you have to routinely spend time deciding which patches to apply and when.

  • Backgroundworker haults in between

    - by Dharmendra
    I am starting a process lets say abc.exe in a background worker. In the begining everything works fine but in between the newly created process i.e. abc.exe haults. Although I am starting abc.exe as hidden window but I come to know about its hang as it stopes doing log writing. When I close my UI form then again abc.exe starts working. Can anybody tell me what could be the possible cause for this? I am not able to debug the issue as it can happen at any time, I can not replicate it. Please tell me as it is very urgent for me. If some more info is required then please revert back.

  • Sharing state/changes across ViewModels

    - by joshperry
    I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

  • Listing and deleting Git commits that are under no branch (dangling?)

    - by Samer Abukhait
    I've got a git repository with plenty of commits that are under no particular branch, I can git show them but when I try to list branches that contain them, it reports back nothing: I thought this is the dangling commits/tree issue (as a result of -D branch), so I pruned the repo, but I still see the case after that: $ git fetch origin $ git fsck --unreachable $ git fsck No output, nothing dangling (right?) $ git show 793db7f272ba4bbdd1e32f14410a52a412667042 commit 793db7f272ba4bbdd1e32f14410a52a412667042 Author: .. But $ git branch --contains 793db7f272ba4bbdd1e32f14410a52a412667042 Gives no output What exactly is the state of that commit? How can I list all commits with similar state, How can I delete commits like those?

  • javascript inserting html code

    - by Marius
    Hello, I have a situation when there's a table and you can add a new row by clicking a button. The row is dynamically generated by a server and it is passed back in HTML. So basically what i need to do is prefix the new row to the old table. Something like this: tableelement.innerHTML = newHtml + tableelement.innerHTML; That surely works, but i have a table header and, obviously, i need to insert the new html after it. How would i do this? insertBefore or insertAfter can't help (afaik), because they're meant for inserting elements and not unparsed HTML. So how could i, having an object of the header's row, insert another row (in HTML) after it (or before) ? Thank you for your ideas

  • Jquery toggle with two elements

    - by Jesse
    I am using a toggle on a graphic to slide out a contact form. The problem is, the contact form can cover up the graphic element on low resolutions. I thought a solution would be to include a "close this" inside the form, that would use the same toggle effect. When I add the close this element to the code, instead of working in tandem with the original graphic element, it starts the chain back over, and slides the contact form even further out. Site is here: http://www.tritonloyaltysupport.com/status Code for toggle here: $(this).html(div_form); //show / hide function $('div.contactable').toggle( function() { $('#overlay').css({display: 'block'}); $('#contactForm').animate({"marginRight": "-=0px"}, "fast"); $('#contactForm').animate({"marginRight": "+=390px"}, "slow"); }, function() { $('#contactForm').animate({"marginRight": "-=390px"}, "slow"); $('#overlay').css({display: 'none'}); } );
