  • using google maps api without a key

    - by Don
    The instructions for v.3 of the Google Maps API say that I should load the Maps API using an API key Curiously it says I should..., rather than I must..... Anyhow, at the moment, I am not using an API key simply because (as far as I can remember) there was no mention of an API key when I was writing the code that calls this API. Should I go back and add an API key to the URL that loads the API? It seems to work fine without the key, so I don't have any particular incentive to do this.

  • Objective-C: how to allocate array of GLuint

    - by sashaeve
    I have an array of GLuint with fixed size: GLuint textures[10]; Now I need to set a size of array dynamically. I wrote something like this: *.h: GLuint *textures; *.m: textures = malloc(N * sizeof(GLuint)); where N - needed size. Then it used like this: glGenTextures(N, &textures[0]); // load texture from image -(GLuint)getTexture:(int)index{ return textures[index]; } I used the answer from here, but program fell in runtime. How to fix this? Program is written on Objective-C and uses OpenGL ES.

  • Where to install shared DLLs on Windows

    - by BruceCran
    I have a driver which can be installed on Windows (XP/Vista/7). It's accessed via a DLL that applications link to, and which is also a Winsock Provider (WSP). It used to be installed under System32, but having seen advice not to, I changed it to install under ProgramFiles instead. Now, the problem is that people are having to either copy it back into System32 or copy it into the application directory whenever they want to use it in their own applications, because Windows won't search the install directory under ProgramFiles when the application tries to load the DLL. I've been unable to find any Microsoft documentation discussing this issue, so if System32 shouldn't be used then where should shared DLLs be installed?

  • Unable to return large result set ORA-22814

    - by rvenugopal
    Hello All I am encountering an issue when I am trying to load a large result set using a range query in Oracle 10g. When I try a smaller range (1 to 100), it works but when I try a larger range(1 and 1000), I get the following error "ORA-22814: attribute or element value is larger than specified in type" error. I have a basic UDT (PostComments_Type) and I have tried using both a VArray and a Table type of PostComments_Type but that hasn't made a difference. Your help is appreciated --Thanks Venu PROCEDURE RangeLoad ( floorId IN NUMBER, ceilingId IN NUMBER, o_PostComments_LARGE_COLL_TYPE OUT PostComments_LARGE_COLL_TYPE -- Tried using as VArray and also Table type of PostComments_Type )IS BEGIN SELECT PostComments_TYPE ( PostComments_ID, ... ) BULK COLLECT INTO o_PostComments_LARGE_COLL_TYPE ------------This is for VARRAY/Table Type. So bulk operation FROM PostComments WHERE PostComments_ID BETWEEN floorId And ceilingId; END RangeLoad;

  • Does an HTTPS SharePoint Site Need to Use HTTPS-Compliant Web Parts?

    - by bporter
    I am new to SharePoint, so this question may be a little naive. However, I sincerely appreciate any help with this. We are planning to create a new sub-site within our company's intranet site, which is built on SharePoint 2007. We want to add a 3rd-party weather web part (which is just a widget to display the local weather forecast) to the home page of the new intranet site. Since the intranet site uses HTTPS, do we need to find an HTTPS-compliant web part? Or, is it possible to use any web part and then configure it to use HTTPS? I'm assuming that if we use a non-HTTPS web part, then users will get some sort of "This page contains both secure and non-secure items" error message when they load the page.

  • Problem with NHibernate and saving - NHibernate doesn't detect changes and uses old values.

    - by Vilx-
    When I do this: Cat x = Session.Load<Cat>(123); x.Name = "fritz"; Session.Flush(); NHibernate detects the change and UPDATEs the DB. But, when I do this: Cat x = new Cat(); Session.Save(x); x.Name = "fritz"; Session.Flush(); I get NULL for name, because that's what was there when I called Session.Save(). Why doesn't NHibernate detect the changes - or better yet, take the values for the INSERT statement at the time of Flush()?

  • Execute a method less times possible - PHP

    - by serhio
    I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

  • Design advices for quick navigation between view

    - by Thomas Joulin
    Usually, when a View requires a lot of bindings, or some UI Elements like a Bing Map, it takes a "while" to load (like between half a second and a second). I don't want a delay between a "tap" action (like tapping an element on a ListBox) and the navigation action (displaying a new page). I don't mind displaying the page progressively. For example, for a Bing Map, I don't mind displaying a black page with only a title, and a second later, having the Map appear. What are the best practices ? It could post a sample if i'm not clear enough

  • Powershell - remote folder availability while counting files

    - by ziklop
    I´m trying to make a Powershell script that reports if there´s a file older than x minutes on remote folder. I make this: $strfolder = 'folder1 ..................' $pocet = (Get-ChildItem \\server1\edi1\folder1\*.* ) | where-object {($_.LastWriteTime -lt (Get-Date).AddDays(-0).AddHours(-0).AddMinutes(-20))} | Measure-Object if($pocet.count -eq 0){Write-Host $strfolder "OK" -foreground Green} else {Write-Host $strfolder "ERROR" -foreground Red} But there´s one huge problem. The folder is often unavailable for me bacause of the high load and I found out when there is no connection it doesn´t report an error but continues with zero in $pocet.count. It means it reports everything is ok when the folder is unavailable. I was thinking about using if(Test-Path..) but what about it became unavailable just after passing Test-Path? Does anyone has a solution please? Thank you in advance

  • chrome extension script is loading twice even more on some pages

  • How are clientside security vulnerabilities generally discovered?

    - by Jehjoa
    I mean in operating systems or their applications. The only way I can think of is examine binaries for the use of dangerous functions like strcpy(), and then try to exploit those. Though with compiler improvements like Visual Studio's /GS switch this possibility should mostly be a thing of the past. Or am I mistaken? What other ways do people use to find vulnerabilities? Just load your target in a debugger, then send unexpected input and see what happens? This seems like a long and tedious process. Could anyone recommend some good books or websites on this subject? Thanks in advance.

  • Adding new "columns" to csv data file in Tcl

    - by George
    Hi All, I am dealing with a "large" measurement data, approximately 30K key-value pairs. The measurements have number of iterations. After each iteration a datafile (non-csv) with 30K kay-value pairs is created. I want to somehow creata a csv file of form: Key1,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... ... Now, I was wondering about efficient way of adding each iteration mesurement data as a columns to csv file in Tcl. So, far it seems that in either case I will need to load whole csv file into some variable(array/list) and work on each element by adding new measurement data. This seems somewhat inefficient. Is there another way, perhaps?

  • Jquery/CSS help needed to make fallback for IE and older browsers

    - by matt_50
    Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

  • Templating Word Documents in C#

    - by NullGeo
    I was wondering if there is a library out there such that it could give me the ability to fill in word templates with custom values. For example: Following could be the content of the Word Document {Address} {PhoneNumber} Hello {Name}, How are you doing? In C# I would like to do something like this to replace all the placeholders in the Word document: using(WordDocument doc = WordDocument.Load("Mail.docx")){ var person = new {Name = "John Smith", Address="42 Wallaby Way, Sydney", PhoneNumber="555-555-5555"}; doc.Template(person); doc.Print(); } The resulting document would look like this: 42 Wallaby Way, Sydney 555-555-5555 Hello John Smith, How are you doing? Any libraries out there (preferably free) that let's me do this? Edit: I am not asking you to find anything that let's me do this. If that was the case, I would do a Google search by myself. Honestly, all I am asking is "has anybody used a library in the past to do this exact thing."

  • Can't access variables from dynamically loaded javascript

    - by Menno
    I'm using a fairly simple system to load javascript dynamically: include = function (url) { var e = document.createElement("script"); e.src = url; e.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(e); }; Let's say I have a file test.js which has the following contents: var foo = 4; Now, in my original script, I want to use include(test.js); console.log(foo); However, I get a 'foo has not been defined' error on this. I'm guessing it has to do with the dynamic script being included as the last child of the <head> tag. How can I get this to work?

  • Facebook, Flash and maintaining state

    - by Myk
    So here's the situation: I have a Flash application I'm deploying to facebook as a canvas app. There are various states within this app - different "pages", sort of. I want to be able to share this app with other users using Facebook's baked-in sharing mechanism. However, I want each state to have its own share button. That way when someone clicks Share on page 3 they are actually sharing page 3, not the root of the whole application. Does anyone know if Facebook exposes some mechanism by which this could be possible? It would be as simple as passing a string into the iFrame that holds the canvas app, so I could load it in as a FlashVar and work from there. I'm kind of beating my head against the wall - does this request make sense, and has anyone tackled anything like this before? Thanks!

  • Can sIFR js files be combined into 1 js file?

    - by Logan Stellway
    In the new sifr 3, the author has implemented the ability to combine the css files into 1 file. There are 4 .js files total and I was wondering if there were any ideas how to combine these files for a faster loading time on the client side and also I was wondering if there was any way to just include the sIFR css styles in an already existing css file. These modifications would greatly decrease the load/waiting time on the end user and I was wondering if there was any thought for that on upcoming builds or if there were any ideas on how to accomplish this idea.

  • Streaming large result sets with MySQL

    - by configurator
    I'm developing a spring application that uses large MySQL tables. When loading large tables, I get an OutOfMemoryException, since the driver tries to load the entire table into application memory. I tried using statement.setFetchSize(Integer.MIN_VALUE); but then every ResultSet I open hangs on close(); looking online I found that that happens because it tries loading any unread rows before closing the ResultSet, but that is not the case since I do this: ResultSet existingRecords = getTableData(tablename); try { while (existingRecords.next()) { // ... } } finally { existingRecords.close(); // this line is hanging, and there was no exception in the try clause } The hangs happen for small tables (3 rows) as well, and if I don't close the RecordSet (which happened in one method) then connection.close() hangs.

  • drop-down combo box-like functionality for queries.

    - by Frank Developer
    Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

  • How to Execute Base Class's ExtractPageData() Before Implementors's ExtractPageData()?

How can I modify this to first run OfflineFactsheetBase's ExtractPageData() and then GenericOfflineCommentary's?
