  • SQLite If Column Exists

    - by Nathan
    I was wondering if there is a nice IF NOT EXISTS for checking columns and indexes in SQLite, or do I need to bring back the entire database schema and validate against that?

  • How do I tell whether my IE is 64-bit? (For that matter, Java too?)

    - by user225626
    Millions of questions already on the web about how to tell whether the OS is 64-bit, but not whether IE and/or Java runtime is 64-bit. Some background: I installed 64-bit Win 7, and IE installed automatically with it from CD; I didn't download IE. I did download Java runtime. Mouseover tips in Control Panel!Programs shows it as: "Java 32-bit Java(TM) Control Panel" Then I went to http://java.com/en/download/manual.jsp and that page says... We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers. But I cannot tell in the aftermath whether my Java is 64-bit. Evidently the "Java(TM) Control Panel" is, but I don't know if that's the same as the runtime. (I'm afraid to ask on the offical Java forums, because they're such a-holes.) Also, How do I issue a command to the OS to tell whether this IE is 64-bit? Help!About doesn't say on that. Thanks.

  • need identical string comparison function in php and java

    - by steelbytes
    I have sorted list of strings that I move between php and java. to be able to bsearch on this data, I need the same comparison function. any idea what string compare functions I can use that will always give the same result in both? eg php's strcmp() vs java's String.compareTo() yes I know I could make my own string compare that does char by char carefully, but I was hoping there's a simple answer. PS, don't care if case sensitive or not, as long as it is consistant.

    - by emmanuel.aquino
    Hello, I'm new here and I'm facing a problem. I need to know if it is possible to implement the WS-Security protocol with X.509 certificates on a native iPhone application. I haven't found much information on the web, except this information from Apple about security services. I just want to ask, is it possible? has it been made before?. If it is posbile, can you point me in the right direction?. Thanks in advance.

  • How to free up memory?

    - by sarego
    We have been facing Out of Memory errors in our App server for sometime. We see the used heap size increasing gradually until finally it reaches the available heap in size. This happens every 3 weeks after which a server restart is needed to fix this. Upon analysis of the heap dumps we find the problem to be objects used in JSPs. Can JSP objects be the real cause of Appserver memory issues? How do we free up JSP objects (Objects which are being instantiated using usebean or other tags)? We have a clustered Websphere appserver with 2 nodes and an IHS.

  • What is the command line syntax to embed MPlayer in an app window in OS X?

    - by Chip
    I know the window ID, and I'm trying stuff like: mplayer -ontop -slave -quiet -wid 471165040 /t.mov mplayer -ontop -slave -quiet --window=471165040 /t.mov but nothing is working. (I know the window ID is correct) Otherwise, mplayer CLI is working great in its own window, just can't get it to play embedded. Can anyone point me to a syntax example of embedding mplayer in an app in OS X? thanks!

  • Check if Django model field choices exists

    - by Justin Lucas
    I'm attempting to check if a value exists in the choices tuple set for a model field. For example lets say I have a Model like this: class Vote(models.Model): VOTE_TYPE = ( (1, "Up"), (-1, "Down"), ) value = models.SmallIntegerField(max_length=1, choices=VOTE_TYPES) Now lets say in a view I have a variable new_value = 'Up' that I would like to use as the value field in a new Vote. How can I first check to see if the value of that variable exists in the VOTE_TYPE tuple? Thank you.

  • How to change font size in a pickerview?

    - by user183804
    I'm fairly new to iPhone programming and am trying to implement a double-component PickerView. At this point the picker works fine in terms of taking user input, created with Interface Builder. However, I need to change the font size to accommodate the text length in each column. I very much would appreciate any link to a straightforward method to creating a multi-component picker with an adjustable font size. Seems like it is not possible if Interface Builder is used to create the picker. So far I have not found any code links that address this issue in detail. Thanks in advance.

  • Project Server 2007 install issue - ProjectEventService won't start

    - by Brian Meinertz
    Trying to install PS2007 with SP1 on Server 2003. The install goes fine, but when running the SharePoint Configuration Wizard, it fails at stage 6 of 12 with the error: Failed to register SharePoint Services. An exception of type System.InvalidOperationException was thrown. Additional exception information: Cannot start service ProjectEventService on computer '.'. From the PSCDiagnostics log: Exception: System.InvalidOperationException: Cannot start service ProjectEventService on computer '.'. --- System.ComponentModel.Win32Exception: The service did not respond to the start or control request in a timely fashion. The ProjectEventService (Microsoft Office Project Server Event) won't even start manually using the Network Service account. Starting the service with a domain account works, but subsequently running the Config Wizard causes the service to be removed and re-provisioned to run using the Network Service account, which again fails. Presumably Network Service needs elevated permissions, but even adding it to the local Admin group makes no difference. Anyone come across this sort of issue before?

  • XAMPP Redirecting to XAMPP directory on Internal Network

    - by user302252
    I installed XAMPP on my desktop. I set up vhosts for about 5 sites and they are all working properly from the desktop itself. The problem arises whenever I try to access these vhosts from my laptop. I changed the hosts file on the laptop to redirect the laptop dev.domain.com requests to the desktop, however, when I try to access these sites from my laptop on the local network, I only receive the XAMPP welcome screen. It seems like when trying to access the vhosts on the desktop from the laptop the vhosts file is ignored as all requests are redirected to the xampp directory. What might I need to adjust to ensure access to the vhosts on the desktop from the laptop?

  • Do you have a development IDE hotkey set in AutoHotkey?

    - by blesh
    I've recently rejoined the AutoHotkey band wagon, and I've been setting up a master script for myself. Generally, I have a few global hotkeys, for doing things like popping open the calculator, and frequently used solutions. I even have a hotkey to restart certain local windows services, I've also got several contextual hotkeys that are only available when certain programs are active, but I don't have anything so far for my common IDE's. I generally develop in VS2008/2010 these days and they have a pretty robust shortcut and code snippet system. Still, I can't help but wonder if anyone out there has come up with a useful set of hotkeys/hotstrings in AutoHotKey for their favorite development environments? I haven't seen much out there, but I'm always interested in ways to cut back my mundane tasks with automation. Does anyone have any AutoHotkey scripts they use primarily for development?

  • llvm preprocessor g++ passes

    - by anon
    Suppose I want to write my own preprocessor. So I want something like this: all *.cpp and *.hpp (even the included ones), before they go to g++, they go: file --> my preprocessor -> g++ Is there a easy way to do this in the LLVM framework? i.e. to add in a stage that says: "after you load up the source file, pipe it through this program before compling it" ? Thanks!

  • Way around 1mb file size restriction?

    - by Sarevok
    My app needs to save files that will range from about 2-20mb. When I tried to do this I was getting an OutOfMemoryException. I did some reading and it's looking like Android has a file size limit of 1mb. Is this correct? If so, is there a way around this limitation, other than splitting up every file into 1mb chunks?

  • Yii: Multi-language website - best practices.

    - by michal
    Hi, I find Yii great framework, and the example website created with yiic shell is a good point to start... however it doesn't cover the topic of multi-language websites, unfortunately. The docs covers the topic of translating short messages, but not keeping the multi-lingual content ... I'm about to start working on a website which needs to be in at least two languages, and I'm wondering what is the best way to keep content for that ... The problem is that the content is mixed extensively with common elements (like embedded video files). I need to avoid duplicating those commons ... so far I used to have an array of arrays containing texts (usually no more than 1-2 short paragraphs), then the view file was just rendering the text from an array. Now I'd like to avoid keeping it in arrays (which requires some attention when putting double quotations " " and is inconvenient in general...). So, what is the best way to keep those short paragraphs? Should I keep them in DB like (id | msg_id | language | content ) and then select them by msg_id & language? That still requires me to create some msg_id's and embed them into view file ... Is there any recommended paradigm for which Yii has some solutions? Thanks, m.

  • C/C++ Control Structure Limitations?

    - by STingRaySC
    I have heard of a limitation in VC++ (not sure which version) on the number of nested if statements (somewhere in the ballpark of 300). The code was of the form: if (a) ... else if (b) ... else if (c) ... ... I was surprised to find out there is a limit to this sort of thing, and that the limit is so small. I'm not looking for comments about coding practice and why to avoid this sort of thing altogether. Here's a list of things that I'd imagine could have some limitation: Number of functions in a scope (global, class, or namespace). Number of expressions in a single statement (e.g., compound conditionals). Number of cases in a switch. Number of parameters to a function. Number of classes in a single hierarchy (either inheritance or containment). What other control structures/language features have limits such as this? Do the language standards say anything about these limits (perhaps minimum requirements for an implementation)? Has anyone run into a particular language limitation like this with a particular compiler/implementation? EDIT: Please note that the above form of if statements is indeed "nested." It is equivalent to: if (a) { //... } else { if (b) { //... } else { if (c) { //... } else { //... } } }

  • How to use "SelectMany" with DataServiceQuery<>

    - by sako73
    I have the following DataServiceQuery running agaist an ADO Data Service (with the update installed to make it run like .net 4): DataServiceQuery<Account> q = (_gsc.Users .Where(c => c.UserId == myId) .SelectMany(c => c.ConsumerXref) .Select(x => x.Account) .Where(a => a.AccountName == "My Account" && a.IsActive) .Select(a => a)) as DataServiceQuery<Account>; When I run it, I get an exception: Cannot specify query options (orderby, where, take, skip) on single resource As far as I can tell, I need to use a version of "SelectMany" that includes an additonal lambda expression (http://msdn.microsoft.com/en-us/library/bb549040.aspx), but I am not able to get this to work correctly. Could someone show me how to properly structure the "SelectMany" call? Thank you for any help.

  • Are there any languages that are dynamically typed but do not allow weak typing?

    - by Maulrus
    For example, adding a (previously undeclared) int and a string in pseudocode: x = 1; y = "2"; x + y = z; I've seen strongly typed languages that would not allow adding the two types, but those are also statically typed, so it's impossible to have a situation like above. On the other hand, I've seen weakly typed languages that allow the above and are statically typed. Are there any languages that are dynamically typed but are also strongly typed as well, so that the piece of code above would not be valid?

  • ETL Operation - Return Primary Key

    - by user302254
    I am using Talend to populate a data warehouse. My job is writing customer data to a dimension table and transaction data to the fact table. The surrogate key (p_key) on the fact table is auto-incrementing. When I insert a new customer, I need my fact table to reflect the id of the related customer. As I mentioned my p_key is auto auto_incrementing so I can't just insert an arbitrary value for the p_key. Any thought on how I can insert a row into my dimension table and still retrieve the primary key to reference in my fact record? Thanks.

  • Strange C++ performance difference?

    - by STingRaySC
    I just stumbled upon a change that seems to have counterintuitive performance ramifications. Can anyone provide a possible explanation for this behavior? Original code: for (int i = 0; i < ct; ++i) { // do some stuff... int iFreq = getFreq(i); double dFreq = iFreq; if (iFreq != 0) { // do some stuff with iFreq... // do some calculations with dFreq... } } While cleaning up this code during a "performance pass," I decided to move the definition of dFreq inside the if block, as it was only used inside the if. There are several calculations involving dFreq so I didn't eliminate it entirely as it does save the cost of multiple run-time conversions from int to double. I expected no performance difference, or if any at all, a negligible improvement. However, the perfomance decreased by nearly 10%. I have measured this many times, and this is indeed the only change I've made. The code snippet shown above executes inside a couple other loops. I get very consistent timings across runs and can definitely confirm that the change I'm describing decreases performance by ~10%. I would expect performance to increase because the int to double conversion would only occur when iFreq != 0. Chnaged code: for (int i = 0; i < ct; ++i) { // do some stuff... int iFreq = getFreq(i); if (iFreq != 0) { // do some stuff with iFreq... double dFreq = iFreq; // do some stuff with dFreq... } } Can anyone explain this? I am using VC++ 9.0 with /O2. I just want to understand what I'm not accounting for here.

  • Does OpenRasta support Mono?

    - by Earlz
    Although Mono support is not a big deal for us, I figured OpenRasta supported it cause it has some commit messages about it.. Well, I tried to build it on Mono and got Ambiguous type references(after manually creating like 10 obj directories.) So I tried just using the prebuilt assemblies I had on hand and that gave me an Object Reference Not Set To Instance of an Object (the usual error I have with mono.. ) at OpenRasta.Diagnostics.DebuggerLoggingTraceListener.WriteAll (using xsp2) Is there official support for Mono or am I missing some sorta extra step for deployment?
