  • Is it possible to edit data in place using CListCtrl - if not, can anyone suggest an alternative con

    - by shan23
    I'm designing a MFC app in which I'd like to have a grid with 2 coloumns : both editable in which the user will input data and the app will get notified about it. The number of rows can be increased/decreased by the user as he wants - What would be the ideal MFC control to use for this kind of requirement ? This is my first time designing a MFC app , so dont mind if it sounds too noobish :)

  • How to override Equals on a object created by an Entity Data Model?

    - by jamone
    I have an Entity Data Model that I have created, and its pulling in records from a SQLite DB. One of the Tables is People, I want to override the person.Equals() method but I'm unsure where to go to make such a change since the Person object is auto-generated and I don't even see where that autogen code resides. I know how to override Equals on a hand made object, its just where to do that on an autogen one.

  • How can I read/write data from a file?

    - by samy
    I'm writing a simple chrome extension. I need to create the ability to add sites URLs to a list, or read from the list. I use the list to open the sites in the new tabs. I'm looking for a way to have a data file I can write to, and read from. I was thinking on XML. I read there is a problem changing the content of files with Javascript. Is XML the right choice for this kinda thing? I should add that there is no web server, and the app will run locally, so maybe the problem websites are having are not same as this. Before I wrote this question, I tried one thing, and started to feel insecure because it didn't work. I made a XML file called Site.xml: <?xml version="1.0" encoding="utf-8" ?> <Sites> <site> <url> http://www.sulamacademy.com/AddMsgForum.asp?FType=273171&SBLang=0&WSUAccess=0&LocSBID=20375 </url> </site> <site> <url> http://www.wow.co.il </url> </site> <site> <url> http://www.Google.co.il </url> </site> I made this script to read the data from him, and put in on the html file. function LoadXML() { var ajaxObj = new XMLHttpRequest(); ajaxObj.open('GET', 'Sites.xml', false); ajaxObj.send(); var myXML = ajaxObj.responseXML; document.write('<table border="2">'); var prs = myXML.getElementsByTagName("site"); for (i = 0; i < prs.length; i++) { document.write("<tr><td>"); document.write(prs[i].getElementsByName("url")[0].childNode[0].nodeValue); document.write("</td></tr>"); } document.write("</table"); }

  • How can I get image data from QTKit without color or gamma correction in Snow Leopard?

    - by Nick Haddad
    Since Snow Leopard, QTKit is now returning color corrected image data from functions like QTMovies frameImageAtTime:withAttributes:error:. Given an uncompressed AVI file, the same image data is displayed with larger pixel values in Snow Leopard vs. Leopard. Currently I'm using frameImageAtTime to get an NSImage, then ask for the tiffRepresentation of that image. After doing this, pixel values are slightly higher in Snow Leopard. For example, a file with the following pixel value in Leopard: [0 180 0] Now has a pixel value like: [0 192 0] Is there any way to ask a QTMovie for video frames that are not color corrected? Should I be asking for a CGImageRef, CIImage, or CVPixelBufferRef instead? Is there a way to disable color correction altogether prior to reading in the video files? I've attempted to work around this issue by drawing into a NSBitmapImageRep with the NSCalibratedColroSpace, but that only gets my part of the way there: // Create a movie NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys : nsFileName, QTMovieFileNameAttribute, [NSNumber numberWithBool:NO], QTMovieOpenAsyncOKAttribute, [NSNumber numberWithBool:NO], QTMovieLoopsAttribute, [NSNumber numberWithBool:NO], QTMovieLoopsBackAndForthAttribute, (id)nil]; _theMovie = [[QTMovie alloc] initWithAttributes:dict error:&error]; // .... NSMutableDictionary *imageAttributes = [NSMutableDictionary dictionary]; [imageAttributes setObject:QTMovieFrameImageTypeNSImage forKey:QTMovieFrameImageType]; [imageAttributes setObject:[NSArray arrayWithObject:@"NSBitmapImageRep"] forKey: QTMovieFrameImageRepresentationsType]; [imageAttributes setObject:[NSNumber numberWithBool:YES] forKey:QTMovieFrameImageHighQuality]; NSError* err = nil; NSImage* image = (NSImage*)[_theMovie frameImageAtTime:frameTime withAttributes:imageAttributes error:&err]; // copy NSImage into an NSBitmapImageRep (Objective-C) NSBitmapImageRep* bitmap = [[image representations] objectAtIndex:0]; // Draw into a colorspace we know about NSBitmapImageRep *bitmapWhoseFormatIKnow = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:getWidth() pixelsHigh:getHeight() bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSCalibratedRGBColorSpace bitmapFormat:0 bytesPerRow:(getWidth() * 4) bitsPerPixel:32]; [NSGraphicsContext saveGraphicsState]; [NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithBitmapImageRep:bitmapWhoseFormatIKnow]]; [bitmap draw]; [NSGraphicsContext restoreGraphicsState]; This does convert back to a 'Non color corrected' colorspace, but the color values NOT are exactly the same as what is stored in the Uncompressed AVI files we are testing with. Also this is much less efficient because it is converting from RGB - "Device RGB" - RGB. Also, I am working in a 64-bit application, so dropping down to the Quicktime-C API is not an option. Thanks for your help.

  • Does a System.Collection.Collection<T> wrap a IList<T> or enumerate over the IList<T> or simply wra

    - by Brian Triplett
    If I am exposing a internal member via a Collection property via: public Collection<T> Entries { get { return new Collection<T>(this.fieldImplimentingIList<T>); } } When this property is called what happens? For example what happens when the following lines of code are called: T test = instanceOfAbove.Entries[i]; instanceOfAbove[i] = valueOfTypeT; It's clear that each time this property is called a new reference type is created but what acctually happens? Does it simply wrap the IList<T> underneath, does it enumerate over the IList<T> and to create a new Collection<T> instance? I'm concerned about performance if this property is used in a for loop.

  • Cannot run an executable binary file on another Linux System??

    - by Claire Huang
    I'm using Ubuntu 10.04 and Qt4.6, and I've created an executable binary file on my own computer through QtCreator. Now I want to put my executable file on CentOS 5, but it seems that this executable file cannot run on CentOS. Do I need to set some compile parameters to make it runnable on Linux other than Ubuntu?? Or do I need to put some lib files with the executable binary file? (For windows, the .exe file should put together with some .dll files to provide the correct dynamic lib linkage, is there some similar problem on linux?) Thanks for your help!

  • Is there a way to get different sizes of the Windows system icons in .NET?

    - by Andrew Watt
    In particular I'd like to be able to get the small (16 x 16) icons at runtime. I tried this: new Icon(SystemIcons.Error, SystemInformation.SmallIconSize) Which supposedly "attempts to find a version of the icon that matches the requested size", but it's still giving me a 32 x 32 icon. I also tried: Size iconSize = SystemInformation.SmallIconSize; Bitmap bitmap = new Bitmap(iconSize.Width, iconSize.Height); using (Graphics g = Graphics.FromImage(bitmap)) { g.DrawIcon(SystemIcons.Error, new Rectangle(Point.Empty, iconSize)); } But that just scales the 32 x 32 icon down into an ugly 16 x 16. I've considered just pulling icons out of the VS Image Library, but I really want them to vary dynamically with the OS (XP icons on XP, Vista icons on Vista, etc.). I'm willing to P/Invoke if that's what it takes.

  • Regex remove everything thats outside { }

    Regex to remove everything outside the { } for example: before: |loader|1|2|3|4|5|6|7|8|9|{"data" : "some data" } after: {"data" : "some data" } with @Marcelo's regex this works but not if there are others {} inside the {} like here: "|loader|1|2|3|4|5|6|7|8|9| {'data': [ {'data':'some data'} ], }"

  • How do you transfer data from SQL Server to db4o?

    - by dde
    I came across this question after searching for a ODBC or JDBC. To my surprise, since I am new to db4o I found there are tools to browse db4o, including a Netbeans and Eclipse plug in. However, when it comes to the question at hand, I only found one company, and the product is not being sold nor demoed (makes me think is not ready yet). So, how do you transfer data? Is there a tool or script I have not found yet?
