• Setting "submit"

  - by user361626

  Driving me a bit nuts this one, have tried alsorts of combination's... At the top of my file I have PHP Code: if (!ISSET ($_POST['submit'])) which tests if the submit has been hit, if not displays the form.... What I'd like to be able to to is generate a link that would be processed directly by the php code that the form would normally be submitted to... (does that make sense ?) so a generated link in the code looks like .. PHP Code: echo '<a href="index.php?submit&s_type=' . $s_type . '&d_height=' . $d_height . '&j_ref=' . $j_ref . '&j_name=' . j_name . '">' . $j_ref . '</a>'; The link generated looks like .. HTML Code: index.php?s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name I have tried setting "submit" with links like HTML Code: index.php?submit=submit&s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name index.php?submit&s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name How do I create a link that sets "submit so it gets processed rather than going through the form ???

• Visual Studio: Collapse Methods, but not Comments (Summary etc.)

  - by Alex

  Hello, is there a way (settings? "macro"? extension?) that I can simply toggle outlining so that only the using section and my methods collapse to their signature line, but my comments (summary and double slash comments) and classes stay expanded? Examples: 1) Uncollapsed using System; using MachineGun; namespace Animals { /// <summary> /// Angry animal /// Pretty Fast, too /// </summary> public partial class Lion { // // Dead or Alive public Boolean Alive; /// <summary> /// Bad bite /// </summary> public PieceOfAnimal Bite(Animal animalToBite) { return animalToBite.Shoulder; } /// <summary> /// Fatal bite /// </summary> public PieceOfAnimal Kill(Animal animalToKill) { return animalToKill.Head; } } } 2) Collapsed (the following is my desired result): using[...] namespace Animals { /// <summary> /// Angry animal /// Pretty Fast, too /// </summary> public partial class Lion { // // Dead or Alive public Boolean Alive; /// <summary> /// Bad bite /// </summary> public PieceOfAnimal Bite(Animal animalToBite)[...] /// <summary> /// Fatal bite /// </summary> public PieceOfAnimal Kill(Animal animalToKill)[...] } } This is how I prefer seeing my class files (the collapsed form). I've been doing the collapsing by hand a million times by now and I think there should be a way to automate/customize/extend VS to do it the way I want? Every time I debug/hit a breakpoint, it uncollapses and messes up things. If I collapse via the context menu's collapse to outline etc. it also collapses my comments which isn't desired. Appreciate your help!

• Insert not working

  - by user1642318

  I've searched evreywhere and tried all suggestions but still no luck when running the following code. Note that some code is commented out. Thats just me trying different things. SqlConnection connection = new SqlConnection("Data Source=URB900-PC\SQLEXPRESS;Initial Catalog=usersSQL;Integrated Security=True"); string password = PasswordTextBox.Text; string email = EmailTextBox.Text; string firstname = FirstNameTextBox.Text; string lastname = SurnameTextBox.Text; //command.Parameters.AddWithValue("@UserName", username); //command.Parameters.AddWithValue("@Password", password); //command.Parameters.AddWithValue("@Email", email); //command.Parameters.AddWithValue("@FirstName", firstname); //command.Parameters.AddWithValue("@LastName", lastname); command.Parameters.Add("@UserName", SqlDbType.VarChar); command.Parameters["@UserName"].Value = username; command.Parameters.Add("@Password", SqlDbType.VarChar); command.Parameters["@Password"].Value = password; command.Parameters.Add("@Email", SqlDbType.VarChar); command.Parameters["@Email"].Value = email; command.Parameters.Add("@FirstName", SqlDbType.VarChar); command.Parameters["@FirstName"].Value = firstname; command.Parameters.Add("@LasttName", SqlDbType.VarChar); command.Parameters["@LasttName"].Value = lastname; SqlCommand command2 = new SqlCommand("INSERT INTO users (UserName, Password, UserEmail, FirstName, LastName)" + "values (@UserName, @Password, @Email, @FirstName, @LastName)", connection); connection.Open(); command2.ExecuteNonQuery(); //command2.ExecuteScalar(); connection.Close(); When I run this, fill in the textboxes and hit the button I get...... Must declare the scalar variable "@UserName". Any help would be greatly appreciated. Thanks.

• Detecting when a cell's detail-disclosure button has been clicked (when using a custom cell XIB)

  - by Gloria

  1 if (cell == nil) 2 { 3 [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; 4 cell = tvCell; 5 self.tvCell = nil; 6 } There's some code from an Apple example of using your own "custom cell XIB" to create cells in a UITableView. It appears to work... but I think I would do better to actually UNDERSTAND what is being done there. Why isn't line #3 assigning the value TO something? cell = [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; (In fact, cell and tvCell aren't being used at all.) Why is line #4 assigning using tvCell when nothing has been put it in at all, yet? Why is line #5 nulling out the tvCell that I need? Why is "@property (nonatomic, assign) IBOutlet UITableViewCell *tvCell;" using assign, not retain? About the only thing I can't get working correctly is when I put a disclosure-button on my custom cell XIB. Is there a way for me to detect when the user has clicked on it? (Hopefully, without using 100s of TAGs.)

• IPhone - Memory Management problems.

  - by user321721

  i am going over my code and trying to get a handle on proper memory management. This code: imageView = [[[UIImageView alloc] initWithImage:myImage] autorelease]; causes my application to crash. I am using multiple view controllers within a nav bar controller. The app works fine, i cant select a person from the first view controller (tableview) and it puts me to a list of that persons photos, i can then select a photo from that view controller (tableview) and move to a final view with a scrollview for viewing the photo. Once i hit back on the navbar the previous view loads (list of photos in a tableview) however the app crashes right before the row is deselected using this code: (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if(RowSelected != nil) { [MainTableView deselectRowAtIndexPath:RowSelected animated:YES]; } } Row selected is stored when a the user clicks a row. If i leave the code as : imageView = [[UIImageView alloc] initWithImage:myImage]; The app runs fine. Am i doing something wrong? do i not need to autorelease this? Thanks!

• What are CDN Best Practices?

  - by Wild Thing

  Hi, I have recently started using the Rackspace Cloudfiles CDN (Limelight), about which I have some questions: I am using jQuery, jQuery UI and jQuery tools in addition to custom JS code. Also, my site is written in ASP.Net, which means there is some ASP.Net generated JS code. Right now what I have done is that I have combined all of the js (including the jquery code), except the ASP.Net generated JS into one file. I am hosting this on the Rackspace CDN. I am wondering if it would make more sense to just get the jQuery, jQuery UI files from the Google hosted CDN (which I suspect would work very well in serving these files, since they will be in many users' cache already)? This would mean one extra HTTP request, so I'm not sure if it'll help. Right now I have multiple containers for my assets. For example, in Rackspace I have 3 containers: JS, CSS and Images. The URL subdomain for all 3 is different. Will that lead to a performance penalty? Should I just use one container (and thus one domain for the CDN)? Is there a way of having the MS ASP.Net generated JS loaded from MS CDN? Would this have a performance hit as per the above question? Thanks in advance, WT

• jQuery code works for console but not in-page.

  - by justSteve

  I have a form element defined as: <div class="field"> <div class="name"> <label for="User_LastName"> Last name: <span class="asterisk">*</span></label> </div> <div class="value"> <%= Html.TextBox("User.LastName", Model.LastName)%> <%= Html.ValidationMessage("User.LastName")%> </div> </div> and a jQuery selector that is supposed to detect when the input gets focus and highlight the parent: $("input").focus(function() { //watching for an event where an input form comes into focus $(this) .parent() .addClass("curFocus") .children("div") .toggle(); }); If i paste this code into firebug's console - things work as planned. However, i'm running this from a 'RenderPartial' .net mvc page. Other jQuery code sitting within the same $(document).ready(function() { block work correctly. The form uses html helpers to generate the inputs which might complicate the process somewhat - but even so... i'm seeing correct behavior when that code's in console but not in a 'real-time' page. How do i troubleshoot this?

• How do I post back information from a webpage that has post-generated content?

  - by meanbunny

  Ok so I am very new to html and the web. Right now I am trying to generate list items on the fly and then have them post back to the web server so I know what the person is trying to obtain. Here is the code for generating the list items: foreach (var item in dataList) { MyDataList.InnerHtml += "<li><a runat='server' onclick='li_Click' id='" + item.Name + "-button'></a></li>"; } Further down I have my click event. protected void li_Click(object sender, EventArgs e) { //How do I determine here which item was actually clicked? } My question is how do I determine which list item was clicked? Btw, the code running behind is C#. EDIT 1 LinkButton link = new LinkButton(); link.ID = "all-button"; link.Text = "All"; link.Click += new EventHandler(link_Click); MyDataList.Controls.Add(link); Then below I have my link_Click event that never seems to hit a breakpoint. void link_Click(object sender, EventArgs e) { if (sender != null) { if (sender.GetType() == typeof(LinkButton)) { LinkButton button = (LinkButton)sender; if (button.ID == "all-button") { } } } } I know this has to be possible I just cant figure out what I am missing. Edit 2 Ok ok I think I know what the problem is. I was trying to add a second list inside of another list. This was causing the whole thing to have problems. It is working now.

• Any guidelines for handling the Headset and Bluetooth AVRC transport controls in Android 2.2

  - by StefanK

  I am trying to figure out what is the correct (new) approach for handling the Intent.ACTION_MEDIA_BUTTON in Froyo. In pre 2.2 days we had to register a BroadcastReceiver (either permanently or at run-time) and the Media Button events would arrive, as long as no other application intercepts them and aborts the broadcast. Froyo seems to still somewhat support that model (at least for the wired headset), but it also introduces the registerMediaButtonEventReceiver, and unregisterMediaButtonEventReceiver methods that seem to control the "transport focus" between applications. During my experiments, using registerMediaButtonEventReceiver does cause both the bluetooth and the wired headset button presses to be routed to the application's broadcast receiver (the app gets the "transport focus"), but it looks like any change in the audio routing (for example unplugging the headset) shits the focus back to the default media player. What is the logic behind the implementation in Android 2.2? What is correct way to handle transport controls? Do we have to detect the change in the audio routing and try to re-gain the focus? This is an issue that any 3rd party media player on the Android platform has to deal with, so I hope that somebody (probably a Google Engineer) can provide some guidelines that we can all follow. Having a standard approach may make headset button controls a bit more predictable for the end users. Stefan

• Collision detection problems...

  - by thyrgle

  Hi, I have written the following: -(void) checkIfLineCollidesWithAll { float slope = ((160-L1Circle1.position.y)-(160-L1Circle2.position.y))/((240-L1Circle1.position.x)-(240-L1Circle2.position.x)); float b = (160-L1Circle1.position.y) - slope * (240-L1Circle1.position.x); if ((240-L1Sensor1.position.x) < (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) < (240-L1Circle2.position.x) || ((240-L1Sensor1.position.x) > (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) > (240-L1Circle2.position.x))) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } else if (slope == INFINITY || slope == -INFINITY) { if (L1Circle1.position.y + 16 >= L1Sensor1.position.y || L1Circle1.position.y - 16 <= L1Sensor1.position.y) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } else if (160-L1Sensor1.position.y + 12 >= slope*(240-L1Sensor1.position.x) + b && 160-L1Sensor1.position.y - 12 <= slope*(240-L1Sensor1.position.x) + b) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } Basically what this does is finds m and b in the well known equation: y = mx + b and then substitutes coordinates of the L1Sensor1 (the circle I'm trying to detect if it it intersects with the line segment) to see if y = mx + b hold true. But, there are two problems, first, when slope approaches infinity the range of what the L1Sensor1 should "react" to (it "reacts" by changing its image) becomes smaller. Also, the code that should handle infinity is not working. Thanks for the help in advanced.

• Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

  - by Andrew Arrow

  Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

• insert data using sqlite issue on iphone ( not reflecting on table)

• XAMPP, MAMP, MySQL, PDO - A deadly combination?

  - by Rich

  Hey folks, Previously I've worked on a Symfony project (MySQL PDO based) with XAMPP, with no problems. Since then, I've moved to MAMP - I prefer this - but have hit a snag with my database connection. I've created a test.php like this: <?php try { $dbh = new PDO('mysql:host=localhost;dbname=xxx;port=8889', 'xxx', 'xxx'); foreach($dbh->query('SELECT * from FOO') as $row) { print_r($row); } $dbh = null; } catch (PDOException $e) { print "Error!: " . $e->getMessage() . "<br/>"; die(); } ?> Obviously the *xxx*s are real db connection details. Which when served by MAMP seems to work fine. From terminal however I keep getting the following error when running the file: Error!: SQLSTATE[28000] [1045] Access denied for user 'xxx'@'localhost' (using password: YES) Not sure if the terminal is aiming at a different MySQL socket or something along those lines; but I've tried pointing it to the MAMP socket with a local php.ini file. Any help would be greatly appreciated.

• Suggestion on Database structure for relational data

  - by miccet

  Hi there. I've been wrestling with this problem for quite a while now and the automatic mails with 'Slow Query' warnings are still popping in. Basically, I have Blogs with a corresponding table as well as a table that keeps track of how many times each Blog has been viewed. This last table has a huge amount of records since this page is relatively high traffic and it logs every hit as an individual row. I have tried with indexes on the fields that are included in the WHERE clause, but it doesn't seem to help. I have also tried to clean the table each week by removing old ( 1.weeks) records. SO, I'm asking you guys, how would you solve this? The query that I know is causing the slowness is generated by Rails and looks like this: SELECT count(*) AS count_all FROM blog_views WHERE (created_at >= '2010-01-01 00:00:01' AND blog_id = 1); The tables have the following structures: CREATE TABLE IF NOT EXISTS 'blogs' ( 'id' int(11) NOT NULL auto_increment, 'name' varchar(255) default NULL, 'perma_name' varchar(255) default NULL, 'author_id' int(11) default NULL, 'created_at' datetime default NULL, 'updated_at' datetime default NULL, 'blog_picture_id' int(11) default NULL, 'blog_picture2_id' int(11) default NULL, 'page_id' int(11) default NULL, 'blog_picture3_id' int(11) default NULL, 'active' tinyint(1) default '1', PRIMARY KEY ('id'), KEY 'index_blogs_on_author_id' ('author_id') ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ; And CREATE TABLE IF NOT EXISTS 'blog_views' ( 'id' int(11) NOT NULL auto_increment, 'blog_id' int(11) default NULL, 'ip' varchar(255) default NULL, 'created_at' datetime default NULL, 'updated_at' datetime default NULL, PRIMARY KEY ('id'), KEY 'index_blog_views_on_blog_id' ('blog_id'), KEY 'created_at' ('created_at') ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

• Datastructure choices for highspeed and memory efficient detection of duplicate of strings

  - by Jonathan Holland

  I have a interesting problem that could be solved in a number of ways: I have a function that takes in a string. If this function has never seen this string before, it needs to perform some processing. If the function has seen the string before, it needs to skip processing. After a specified amount of time, the function should accept duplicate strings. This function may be called thousands of time per second, and the string data may be very large. This is a highly abstracted explanation of the real application, just trying to get down to the core concept for the purpose of the question. The function will need to store state in order to detect duplicates. It also will need to store an associated timestamp in order to expire duplicates. It does NOT need to store the strings, a unique hash of the string would be fine, providing there is no false positives due to collisions (Use a perfect hash?), and the hash function was performant enough. The naive implementation would be simply (in C#): Dictionary<String,DateTime> though in the interest of lowering memory footprint and potentially increasing performance I'm evaluating a custom data structures to handle this instead of a basic hashtable. So, given these constraints, what would you use? EDIT, some additional information that might change proposed implementations: 99% of the strings will not be duplicates. Almost all of the duplicates will arrive back to back, or nearly sequentially. In the real world, the function will be called from multiple worker threads, so state management will need to be synchronized.

• Stopping a MATLAB GUI callback

  - by leonhart88

  Dear All, I have a START and STOP button. When I hit START, i run a bunch of code in my callback. It's basically a sequential "script" that opens valves, dispenses water and then closes the valves...there is no while() loop and it doesn't repeat. I want to be able to stop this process at any time using the STOP button. Most of the related answers I've seen are in the cases where a while() loop is used. Some people have also suggested to periodically check if the STOP button was pressed (using a variable or handle variable). Since I do not have a while loop, I can't solve it that way. Also, I'd like to be able to exit immediately, without having to periodically check (because checking multiple times in my code would be ugly and confusing). Is there a way to terminate the callback which was interrupted by the STOP button? If not, is it possible to have the START button run a .m file and then have the STOP button terminate that .m file? The worst case scenario would be to check a variable periodically. UPDATE: Well, looks like the worst case scenario is what is suggested by MATLAB... http://www.mathworks.com/support/solutions/en/data/1-33IK85/index.html?product=ML&solution=1-33IK85 Thanks.

• Looping through covariates in regression using R

  - by Kyle Peyton

  I'm trying to run 96 regressions and save the results as 96 different objects. To complicate things, I want the subscript on one of the covariates in the model to also change 96 times. I've almost solved the problem but I've unfortunately hit a wall. The code so far is, for(i in 1:96){ assign(paste("z.out", i,sep=""), lm(rMonExp_EGM~ TE_i+ Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies)) } This works on the object creation side (e.g. I have z.out1 - z.out96) but I can't seem to get the subscript on the covariate to change as well. I have 96 variables called TE_1, TE_2 ... TE_96 in the dataset. As such, the subscript on TE_, the "i" needs to change to correspond to each of the objects I create. That is, z.out1 should hold the results from this model: z.out1 <- lm(rMonExp_EGM~ TE_1 + Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies) And z.out96 should be: z.out96 <- lm(rMonExp_EGM~ TE_96+ Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies) Hopefully this makes sense. I'm grateful for any tips/advice. cheers, kyle

• RegEx expression or jQuery selector to NOT match "external" links in href

  - by TrueBlueAussie

  I have a jQuery plugin that overrides link behavior, to allow Ajax loading of page content. Simple enough with a delegated event like $(document).on('click','a', function(){});. but I only want it to apply to links that are not like these ones (Ajax loading is not applicable to them, so links like these need to behave normally): target="_blank" // New browser window href="#..." // Bookmark link (page is already loaded). href="afs://..." // AFS file access. href="cid://..." // Content identifiers for MIME body part. href="file://..." // Specifies the address of a file from the locally accessible drive. href="ftp://..." // Uses Internet File Transfer Protocol (FTP) to retrieve a file. href="http://..." // The most commonly used access method. href="https://..." // Provide some level of security of transmission href="mailto://..." // Opens an email program. href="mid://..." // The message identifier for email. href="news://..." // Usenet newsgroup. href="x-exec://..." // Executable program. href="http://AnythingNotHere.com" // External links Sample code: $(document).on('click', 'a:not([target="_blank"])', function(){ var $this = $(this); if ('some additional check of href'){ // Do ajax load and stop default behaviour return false; } // allow link to work normally }); Q: Is there a way to easily detect all "local links" that would only navigate within the current website? excluding all the variations mentioned above. Note: This is for an MVC 5 Razor website, so absolute site URLs are unlikely to occur.

• Extremely Difficult Problem with ASP.Net 4.0 WebForms app using Routing

  - by dudeNumber4

  I have a completed app running in a QA environment. Everything works fine under most circumstances. If you hit a plain URL (no identifying information in the URL), you see an intro page with a button (generated by an asp LinkButton control) that posts back and directs you to another page. The markup looks the same when it fails and when it doesn't. When such a URL is followed from, e.g., Word and the default browser is IE, the intro page loads fine, but clicking the button causes an error. When not debugging, this behavior occurs every time. While debugging, the error occurs only ~ 1 in 10 times (closing the browser instance and starting over every time). When the error occurs, the intro page Page_Load fires and IsPostBack is false. Somehow, instead of a post, a get is being issued. When I run fiddler to try to analyze the actual calls (can't use firebug because it never happens using Firefox), everything works every time. I don't know whether this issue has anything to do with routing, and I've no idea even what to look at next. The strange thing is, when I debug, the intro page doesn't fully load every time. Only about 1 in 3 times does it fully load even if I've just cleared browser cache. When I run it through fiddler, it fully loads and works fine every time.

• How to make last div stretch to fill screen?

  - by Conor

  I have a site I'm trying to build and I've hit one little snag thats driving me insane. Essentially on pages without enough content to fill the viewport, I want to have the last div (my footer, fill the rest of the viewport, but it's currently being cut off. My html looks like this: <body> <div id="header"> </div> <div id="subNav"> </div> <div id="content"> </div> <div id="footer"> </div> </body> I tried using html, body, footer { height:100%; } but that creates much more space then needed, essentially a full screen length of blank content in the footer. How do I get my footer just to fill teh rest of the screen without adding a scroll bar? Thanks in advance, One Frustrated Coder.

• entity framework navigation property further filter without loading into memory

  Hi, I've two entities with 1 to N relation in between. Let's say Books and Pages. Book has a navigation property as Pages. Book has BookId as an identifier and Page has an auto generated id and a scalar property named PageNo. LazyLoading is set to true. I've generated this using VS2010 & .net 4.0 and created a database from that. In the partial class of Book, I need a GetPage function like below public Page GetPage(int PageNumber) { //checking whether it exist etc are not included for simplicity return Pages.Where(p=>p.PageNo==PageNumber).First(); } This works. However, since Pages property in the Book is an EntityCollection it has to load all Pages of a book in memory in order to get the one page (this slows down the app when this function is hit for the first time for a given book). i.e. Framework does not merge the queries and run them at once. It loads the Pages in memory and then uses LINQ to objects to do the second part To overcome this I've changed the code as follows public Page GetPage(int PageNumber) { MyContainer container = new MyContainer(); return container.Pages.Where(p=>p.PageNo==PageNumber && p.Book.BookId==BookId).First(); } This works considerably faster however it doesn't take into account the pages that have not been serialized to the db. So, both options has its cons. Is there any trick in the framework to overcome this situation. This must be a common scenario where you don't want all of the objects of a Navigation property loaded in memory when you don't need them.

• WindowsFormsApplicationBase SplashScreen makes login form ignore keypresses until I click on it - how to debug?

  - by Tom Bushell

  My WinForms app has a simple modal login form, invoked at startup via ShowDialog(). When I run from inside Visual Studio, everything works fine. I can just type in my User ID, hit the Enter key, and get logged in. But when I run a release build directly, everything looks normal (the login form is active, there's a blinking cursor in the User ID MaskedEditBox), but all keypresses are ignored until I click somewhere on the login form. Very annoying if you are used to doing everything from the keyboard. I've tried to trace through the event handlers, and to set the focus directly with code, to no avail. Any suggestions how to debug this (outside of Visual Studio), or failing that - a possible workaround? Edit Here's the calling code, in my Main Form: private void OfeMainForm_Shown(object sender, EventArgs e) { OperatorLogon(); } private void OperatorLogon() { // Modal dialogs should be in a "using" block for proper disposal using (var logonForm = new C21CfrLogOnForm()) { var dr = logonForm.ShowDialog(this); if (dr == DialogResult.OK) SaveOperatorId(logonForm.OperatorId); else Application.Exit(); } } Edit 2 Didn't think this was relevant, but I'm using Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase for it's splash screen and SingleInstanceController support. I just commented out the splash screen code, and the problem has disappeared. So that's opened up a whole new line of inquiry... Edit 3 Changed title to reflect better understanding of the problem

• How can I optimize this loop?

  - by Moshe

  I've got a piece of code that returns a super-long string that represents "search results". Each result is represented by a double HTML break symbol. For example: Result1<br><br>Result 2<br><br>Result3 I've got the following loop that takes each result and puts it into an array, stripping out the break indicator, "kBreakIndicator" (<br><br>). The problem is that this lopp takes way too long to execute. With a few results it's fine, but once you hit a hundred results, it's about 20-30 seconds slower. It's unacceptable performance. What can I do to improve performance? Here's my code: content is the original NSString. NSMutableArray *results = [[NSMutableArray alloc] init]; //Loop through the string of results and take each result and put it into an array while(![content isEqualToString:@""]){ NSRange rangeOfResult = [content rangeOfString:kBreakIndicator]; NSString *temp = (rangeOfResult.location != NSNotFound) ? [content substringToIndex:rangeOfResult.location] : nil; if (temp) { [results addObject:temp]; content = [[[content stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@%@", temp, kBreakIndicator] withString:@""] mutableCopy] autorelease]; }else{ [results addObject:[content description]]; content = [[@"" mutableCopy] autorelease]; } } //Do something with the results array. [results release];

• Python programming - Windows focus and program process

  - by Zack

  I'm working on a python program that will automatically combine sets of files based on their names. Being a newbie, I wasn't quite sure how to go about it, so I decided to just brute force it with the win32api. So I'm attempting to do everything with virtual keys. So I run the script, it selects the top file (after arranging the by name), then sends a right click command,selects 'combine as adobe PDF', and then have it push enter. This launched the Acrobat combine window, where I send another 'enter' command. The here's where I hit the problem. The folder where I'm converting these things loses focus and I'm unsure how to get it back. Sending alt+tab commands seems somewhat unreliable. It sometimes switches to the wrong thing. A much bigger issue for me.. Different combination of files take different times to combine. though I haven't gotten this far in my code, my plan was to set some arbitrarily long time.sleep() command before it finally sent the last "enter" command to finish and confirm the file name completing the combination process. Is there a way to monitor another programs progress? Is there a way to have python not execute anymore code until something else has finished?
