  • Set focus on textbox after postback.

    - by Niike2
    I have a search page with 3 TextBoxes that users can filter a search with. I have put the focus on the TextBox that contains text. If more than one contains text just focus on last TextBox. private void SetFocusOnTextBox(ControlCollection ctrlCollection) { foreach (Control ctrl in ctrlCollection) { if (ctrl.GetType() == typeof(TextBox)) { if (((TextBox)ctrl).Text != string.Empty) { SetFocus(ctrl); } } } } After the code runs and a user searches, the focus comes to the beginning of the TextBox, not the end where it would be presumed. How to put insert marked at the end of that TextBox?

  • Crawling not working windows2008

    - by axtolf
    Hi, We installed a new MOSS 2007 farm on windows 2008 SP2 enviroment. We used SQL2008 too. Configuration is 1 index, 1 FE and 1 server with 2008, all on ESX 4.0. All the Service that need it uses a dedicated user, so search has a dedicated user. Installation went well and we found no problem. We installed an SP1 MOSS from a ISO and after we upgraded WSS and MOSS to SP2. We installed the Italian language pack too and patched it to SP2. We created a new SSP. We created a web application and created a root website under it. The problem is that we can't male crawling work in any way. Seems that crawling is not able to reach the web application that we want to crawl. In event viewer of the index we have this error when we try to crawl it: The start address <h..p://name.domain.it:81 cannot be crawled. Context: Application 'SSP1', Catalog 'Portal_Content' Details: The object was not found. (0x80041201) The log of crawling from the search admin, only says: h..p://name.domani.it:81 The object was not found. (The item was deleted because it was either not found or the crawler was denied access to it.) The domain is fully accessible from everywhere using both farm admin user or the search user that we are using for service to run. Site is fully accessible from the index and seem not have problem. Inside the we application we created a root site collection with a couple of file. The log of the farm simply says.... nothing! When we ask to do a full crawl of the site, it runs for a second and after we have the errors that I wrote above. But the farm's log says nothing. Any suggestion or help is really appreciated since we are losing a lot of time on it and really we do not have any idea of what's wrong about this farm.

  • Forth: free video tutorials?

    - by Peter Mortensen
    Can you recommend any free Forth video tutorials (except for following) ? The only one I know of is Samuel A. Falvo's excellent "Over The Shoulder Episode 1: Text Preprocessing in Forth". MPEG. 102 MB. There are also videos from the annual Forth Day, but I don't consider those to be tutorials. (Unfortunately Forth is, like R, C, C++, Java, C#, D, COM, .NET, F# and Frontier, an unspecific search term. Search tip for Forth: qualify it with "ans" - as in ANS Forth, the ANSI Forth Standard.)

  • MYSQL: Like Method, Similar Words - But Don't Show the Searched Word

    - by elmaso
    Hello, actually i use this method to show similar words for a search request.. $query = "SELECT * FROM searches WHERE Query LIKE '%$search%' ORDER BY Query"; if someone searches for "nelly" it looks up in the database for similar words "nelly furtado, nelly ft. kelly"... but i dont want to show up the searched word.. example: you've searched for nelly - try this too: nelly, nelly furtado, nelly ft., the bold word should not showed up again, because it's the searched word.. is there maybe a method with MATCH AGAINST? thank you!

  • Linear layout and custom dialog

  • Nice shadow effect in text (UISegmentedControl)

    - by Matthias
    Hi, I would like to bring some color to the texts of my UISegmentedControl. So, I've searched a bit about this topic, but it seems to be not possible out-of-the-box. But I found this nice blog post (link text), how to build an image out of a custom text and then assign it to the segemented control. Works fine, but the text in these created images do not have this nice little shadow effect as the original ones. So, does anyone know, how to create such a shadow effect? I guess, Apple does the same (building an image for the text) with the standard segmenented control. Thanks for your help. Regards Matthias

  • C# Confusing Results from Performance Test

    - by aip.cd.aish
    I am currently working on an image processing application. The application captures images from a webcam and then does some processing on it. The app needs to be real time responsive (ideally < 50ms to process each request). I have been doing some timing tests on the code I have and I found something very interesting (see below). clearLog(); log("Log cleared"); camera.QueryFrame(); camera.QueryFrame(); log("Camera buffer cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); Each time the log is called the time since the beginning of the processing is displayed. Here is my log output: [3 ms]Log cleared [41 ms]Camera buffer cleared [41 ms]Sx: 589 Sy: 414 [112 ms]Camera output acuired for processing The timings are computed using a StopWatch from System.Diagonostics. QUESTION 1 I find this slightly interesting, since when the same method is called twice it executes in ~40ms and when it is called once the next time it took longer (~70ms). Assigning the value can't really be taking that long right? QUESTION 2 Also the timing for each step recorded above varies from time to time. The values for some steps are sometimes as low as 0ms and sometimes as high as 100ms. Though most of the numbers seem to be relatively consistent. I guess this may be because the CPU was used by some other process in the mean time? (If this is for some other reason, please let me know) Is there some way to ensure that when this function runs, it gets the highest priority? So that the speed test results will be consistently low (in terms of time). EDIT I change the code to remove the two blank query frames from above, so the code is now: clearLog(); log("Log cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); The timing results are now: [2 ms]Log cleared [3 ms]Sx: 589 Sy: 414 [5 ms]Camera output acuired for processing The next steps now take longer (sometimes, the next step jumps to after 20-30ms, while the next step was previously almost instantaneous). I am guessing this is due to the CPU scheduling. Is there someway I can ensure the CPU does not get scheduled to do something else while it is running through this code?

  • jQuery selective hover

    - by Vitor
    Hello everyone, I'm trying to do a simple task with jQuery: I have a list of words which, when hovered, should fadeIn its corresponding image. For example: <a href="#" class="yellow">Yellow</a> <a href="#" class="blue">Blue</a> <a href="#" class="green">Green</a> <img src="yellow.jpg" class="yellow"> <img src="blue.jpg" class="blue"> <img src="green.jpg" class="green"> I'm currently doing it this way for each link/image: $('a.yellow').hover( function () { $('img.yellow').fadeIn('fast'); }, function () { $('img.yellow').fadeOut('fast'); }); The method above works fine, but as I'm still learning, I guess there's a better way to do that instead of repeating functions. Can anyone give me some light here? How can I improve this code?

  • Best practices for combining Lucene.NET and a relational database?

    - by FlySwat
    I'm working on a project where I will have a LOT of data, and it will be searchable by several forms that are very efficiently expressed as SQL Queries, but it also needs to be searched via natural language processing. My plan is to build an index using Lucene for this form of search. My question is that if I do this, and perform a search, Lucene will then return the ID's of matching documents in the index, I then have to lookup these entities from the relational database. This could be done in two ways (That I can think of so far): N amount of queries (Horrible) Pass all the ID's to a stored procedure at once (Perhaps as a comma delimited parameter). This has the downside of being limited to the max parameter size, and the slow performance of a UDF to split the string into a temporary table. I'm almost tempted to mirror everything into lucenes index, so that I can periodicly generate the index from the backing store, but only need to access it for the frontend. Advice?

  • UIScrollView ImageView with pins on top

    - by Koppo
    To all, I have a UIScrollView which has a UIImageView. I want to show pins on this imageView. When I add pins as subviews of the ImageView everything is great except for when you zoom the scale transform happens on the pins also. I don't want this behavior and want my pins to stay the same. So I choose to add the Pins to another view which sits on top of the ImageView and is also a subview of the UIScrollView. The idea here if you will imagine is to have a layer which hovers over the map and won't scale yet show pins over where I plot them. The pin when added to the layer view don't cale if the ImageView scales. However the issue then bceomes the position of the pins doesn't match the original origin x/y as the ImageView has had a scale transform. Basically this is a custom map of a place with Pins. I am trying to have the Pins float over and not zoom in and out over my ImageView yet remember where I placed them when the zoom happens. Some code scrollView = [[UIScrollView alloc] initWithFrame:viewRect]; scrollView.delegate = self; scrollView.pagingEnabled = NO; scrollView.scrollsToTop = NO; [scrollView setBackgroundColor:[UIColor clearColor]]; scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView.bounces = YES; scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight; scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; imageViewMap = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; imageViewMap.userInteractionEnabled = YES; viewRect = CGRectMake(0,0,imageViewMap.image.size.width,imageViewMap.image.size.height); //viewRect = CGRectMake(0,0,2976,3928); [scrollView addSubview:imageViewMap]; [scrollView setContentSize:CGSizeMake(viewRect.size.width, viewRect.size.height)]; iconsView = [[UIView alloc] initWithFrame:imageViewMap.frame]; [scrollView addSubview:iconsView]; Code to add Pin later on some event. [iconsView addSubview:pinIcon]; I am stuck in trying tp figure out how to to get my pins to hover on the map without moving when the scale happens. Thanks

  • How to use PropertyCriteria on complex property?

    - by user1394710
    I'm new to EPiSERVER. Currently trying to search for a page with a specific property set to a specific value. I need the property CatalogEntryPoint (a ContentReference) to equal something. Here is the criterea: PropertyCriteria secCriteria = new PropertyCriteria(); secCriteria.Condition = CompareCondition.Equal; secCriteria.Name = "CatalogEntryPoint.ID"; secCriteria.Type = PropertyDataType.Number; secCriteria.Value = currentContent.ContentLink.ID.ToString(); secCriteria.Required = true; And here is an excerpt from the search index: { "CatalogEntryPoint": { "$type": "EPiServer.Find.Cms.IndexableContentReference, EPiServer.Find.Cms", "ID$$number": 1073742170, "WorkID$$number": 0, "ProviderName$$string": "CatalogContent", "GetPublishedOrLatest$$bool": false, "IsExternalProvider$$bool": true, "___types": [ "EPiServer.Find.Cms.IndexableContentReference", "EPiServer.Core.ContentReference", "System.Object", "System.IComparable", "EPiServer.Data.Entity.IReadOnly" ] }, It would seem that the CatalogEntryPoint.ID-notation does not work as I'm getting 0 results. How should I write it?

  • Drawing performance with CGImageCreateWithJPEGDataProvider?

    - by Rnegi
    I've actually curious about this for the iPhone. I am getting an MJPEG stream from a server and trying to render it natively on the iphone (without the use of safari class). Reasons for this is because the safari class while CAN render MJPEG natively, does not do so at the framerate I would like. So I tried drawing it natively, but I've come up with performance issues, namely a syncing issue between what I'm getting from the server and what I am able to draw onto the screen of the phone. (There should be a little lag, but the drift gets really bad, which is what I want to avoid). So I have a connection set up to my server and I do get the JPEGS. It's just data I insert into a NSMutableArray buffer CFMutableDataRef _t_data_ref = (CFMutableDataRef)[_buffer_array objectAtIndex:0]; //CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData (_cf_buffer_data); CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData(_t_data_ref); CGImageRef image = CGImageCreateWithJPEGDataProvider(imgDataProvider, NULL, true, kCGRenderingIntentDefault); CGImageRef imgRef = image; CGContextDrawImage(context, CGRectMake(0, 17, 380, 285), imgRef); CGImageRelease(image); CGDataProviderRelease(imgDataProvider); please note this is the gist of my code, but it should summarize what I am trying to accomplish with regards to drawing. Also in order to get the framerate in sync, I had to detach a separate thread that sleeps X seconds and calls [self setNeedsDisplay]. NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Top-level pool while(1) { //[NSThread sleepForTimeInterval:TIMER_REFRESH_VALUE]; //sleep(unsigned int ); usleep(MICRO_REFRESH_VALUE); if ([_buffer_array count] > 10) { //NSLog(@"stuff %d", [_buffer_array count]); //[self setNeedsDisplay]; [self performSelectorOnMainThread:@selector(setNeedsDisplay) withObject:nil waitUntilDone:NO]; } } [pool release]; // Release the objects in the pool. My buffer of jpeg data actually fills up quite quick, but I can't seem to actually consume what i'm getting at the same rate, actually much slower. Are there any documents that can describe what kind of performance tuning I can do to make it go faster when rendering the JPEG to the screen? Or am I kind of stuck here? Thanks!

  • MkMapView setRegion animation prevents touch events on Annotation Views

    - by Vlad Gurovich
    Hi there! We have a MKmapView with a bunch of Image Annotation where each Image annotation responds to touch by overriding these methods of AnnotationView subclass: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event Our map region is updated using [MkMapView setRegion:animated:] whenever the new location is received and is far enough from the old location to make a difference. What I noticed is that if we set animated flag to YES the touches on our annotation are rarely detected(probably due to the fact that main thread is busy animating between two map regions. When we set animated flag to NO, everything is fine, but map transition may(or may not) become jerky. The question I have is whether this is an expected behavior of animated flag of [MkMapView setRegion:animated] function or whether there is a workaround for this issue. Thanks in advance

I simply need to create a sequence of strings, image1.jpg, image2.jpg, etc etc ie in a loop var imgString:String='image'+i+'.jpg; I assume a best practice is to use a NSMutableString with appendString method?

  • how to build an accumulator array in matlab

    - by schwiz
    I'm very new to matlab so sorry if this is a dumb question. I have to following matrices: im = imread('image.jpg'); %<370x366 double> [y,x] = find(im); %x & y both <1280x1 double> theta; %<370x366 double> computed from gradient of image I can currently plot points one at a time like this: plot(x(502) + 120*cos(theta(y(502),x(502))),y(502) + 120*sin(theta(y(502),x(502))),'*b'); But what I want to do is some how increment an accumulator array, something like this: acc = zeros(size(im)); acc(y,x) = acc(x + 120*cos(theta(y,x)),y + 120*sin(theta(y,x)),'*b')) + 1; It would be nice if the 120 could actually be another matrix containing different radius values as well.

  • Cassandra or mysql 5

    - by saturngod
    Should I use cassandra in 100,000 users project ? In mysql 5 have full text search and partition table. I'm starting to make Question and answer system like stackoverflow with CodeIgniter. It's move from vbulletin to new system. In old vbulletin have around 100,000 users and total post is around 80,000. In next 3 or 4 year, users and posts will be more and more. So, Should I use cassandra instead of mysql 5 ? If I use cassandra, I need to change gridserver in mediatemple to DV server in mediatemple. Cassandra is not built in hosting system. So, I must use VPS or DV server. If I use mysql 5, hosting is not problem but how about speed and search. Btw, What database using in Stack Over ?
