  • Git: changes not reflecting on other checkouts - huh?

    - by Chad Johnson
    Okay, so, I have my branches (git branch -a): * chat master remotes/origin/HEAD -> origin/master remotes/origin/chat I make changes (still with the 'chat' branch checkout out), commit, and push. I go to my server, on which I have a clone of the repository, and I do a fetch: git getch then I switch to the chat branch: git checkout --track -b chat origin/chat and I event do a pull, just to make sure everything is up to date: git pull and my changes from my other computer are NOT. THERE. What the heck am I doing wrong? If I had hair, I would have pulled it out. Thankfully I am bald. When I try a 'git commit' again, I get this # On branch chat # Changed but not updated: # (use "git add/rm <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: app/controllers/chat_controller.rb # modified: app/views/dashboard/index.html.erb # modified: app/views/dashboard/layout.js.erb # modified: app/views/layouts/dashboard.html.erb # deleted: app/views/project/.tmp_edit.html.erb.55742~ # deleted: app/views/project/.tmp_edit.html.erb.83482~ # modified: public/stylesheets/dashboard/layout.css # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .loadpath # .project # config/database.yml # config/environments/development.yml # config/environments/production.yml # config/environments/test.yml # log/ no changes added to commit (use "git add" and/or "git commit -a")

  • Why is Firefox so bloated? [closed]

    - by bvandrunen
    First off I am a developer who loves firebug and other development tools (and no Chrome firebug lite does not cut it) and am just utterly frustrated when I have been using Firefox lately. It is at the point where I use Chrome for absolutely everything but web development but am still frustrated that I had to switch where half a year ago or more Firefox was fine. Why can't there be a Firefox lite? One that is free from all the bloat that has been plaguing Firefox recently. Also if there are any tools or tips that I can free up my Firefox that would be great. I am using the newest version + as few add-ons as possible. EDIT: I have tried Chrome Developer Tools and I do like them...but I can't get passed the firebug lite extension of Chrome. Some of the developer tools are great but sometimes they just have too much information. I extensively use Firebug/myphp admin. Both of these work much much better in Firefox then Chrome. But I hate that it takes me so much longer to load and use everything.

  • problem with insert into mysql DB using PHP

    - by user504363
    Hi all I have strange problem that I have a PHP page used to insert data into Mysql DB. the problem is that when I execute the code, nothing added to db and no errors is appeared although I set display errors codes error_reporting(E_ALL); ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE); any idea about this problem ! here is my used code for inserting function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") { if (PHP_VERSION < 6) { $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; } $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue); switch ($theType) { case "text": $theValue = ($theValue != "") ?

  • EF/LINQ: Where() against a property of a subtype

    - by ladenedge
    I have a set of POCOs, all of which implement the following simple interface: interface IIdObject { int Id { get; set; } } A subset of these POCOs implement this additional interface: interface IDeletableObject : IIdObject { bool IsDeleted { get; set; } } I have a repository hierarchy that looks something like this: IRepository<T <: BasicRepository<T <: ValidatingRepository<T (where T is IIdObject) I'm trying to add a FilteringRepository to the hierarchy such that all of the POCOs that implement IDeletableObject have a Where(p => p.IsDeleted == false) filter applied before any other queries take place. My goal is to avoid duplicating the hierarchy solely for IDeletableObjects. My first attempt looked like this: public override IQueryable<T> Query() { return base.Query().Where(t => ((IDeletableObject)t).IsDeleted == false); } This works well with LINQ to Objects, but when I switch to an EF backend I get: "LINQ to Entities only supports casting Entity Data Model primitive types." I went on to try some fancier parameterized solutions, but they ultimately failed because I couldn't make T covariant in the following case for some reason I don't quite understand: interface IQueryFilter<out T> // error { Expression<Func<T, bool>> GetFilter(); } I'd be happy to go into more detail on my more complicated solutions if it would help, but I think I'll stop here for now in hope that someone might have an idea for me to try. Thanks very much in advance!

  • Problem with UITextView

    - by user367039
    I have a strange problem with trying to pass a string from one viewcontroller to another view controller if the string originates from a UITextview instead of UITextfield. Both UITextview.text and UITextfield.text are of type NSString. The following code takes either Textfield.text or Textview.text depending on the fieldType and puts it into a string called aString. NSString *aString = [[NSString alloc] init]; if (fieldType == 3) { aString = textView.text; } else { aString = textField.text; } When I examine aString on either cases, I can see that it has successfully assigned the text into aString. I then pass the string to the other view controller using this code. [delegate updateSite:aString :editedFieldKey :fieldType]; [self.navigationController popViewControllerAnimated:YES]; This works fine if aString originated from textfield.text but nothing happens except the view controller is popped if aString was from textview.text This is the code that takes aString and does stuff with it, however it doesn't even execute the first line of code "NSLog(@"Returned object: %@, field type:%@", aString,editedFieldKey);" if aString was from textview.text Any help will be appreciated. -(void)updateSite:(NSString *)aString :(NSString *)editedFieldKey :(int)fieldType { NSLog(@"Returned object: %@, field type:%@", aString,editedFieldKey); switch (fieldType) { case 0: //string [aDiveSite setValue:aString forKey:editedFieldKey] ; NSLog(@"String set %@",[aDiveSite valueForKey:editedFieldKey] ); break; case 1: //int [aDiveSite setValue:[NSNumber numberWithInt:aString.intValue] forKey:editedFieldKey]; NSLog(@"Integer set"); break; case 2: //float NSLog(@"Saving floating value"); [aDiveSite setValue:[NSNumber numberWithFloat:aString.floatValue] forKey:editedFieldKey]; NSLog(@"Float set"); break; case 3: //Text view [aDiveSite setValue:aString forKey:editedFieldKey]; NSLog(@"Textview text saved"); default: break; } [self.tableView reloadData]; }

  • .NET MissingMethodException occuring on one of thousands of end-user machines -- any insight?

    - by Yoooder
    This issue has me baffled, it's affecting a single user (to my knowledge) and hasn't been reproduced by us... The user is receiving a MissingMethodException, our trace file indicates it's occuring after we create a new instance of a component, when we're calling an Initialize/Setup method in preparation to have it do work (InitializeWorkerByArgument in the example) The Method specified by the error is an interface method, which a base class implements and classes derived from the base class can override as-needed The user has the latest release of our application All the provided code is shipped within a single assembly Here's a very distilled version of the component: class Widget : UserControl { public void DoSomething(string argument) { InitializeWorkerByArgument(argument); this.Worker.DoWork(); } private void InitializeWorkerByArgument(string argument) { switch (argument) { case "SomeArgument": this.Worker = new SomeWidgetWorker(); break; } // The issue I'm tracking down would have occured during "new SomeWidgetWorker()" // and would have resulted in a missing method exception stating that // method "DoWork" could not be found. this.Worker.DoWorkComplete += new EventHandler(Worker_DoWorkComplete); } private IWidgetWorker Worker { get; set; } void Worker_DoWorkComplete(object sender, EventArgs e) { MessageBox.Show("All done"); } } interface IWidgetWorker { void DoWork(); event EventHandler DoWorkComplete; } abstract class BaseWorker : IWidgetWorker { virtual public void DoWork() { System.Threading.Thread.Sleep(1000); RaiseDoWorkComplete(this, null); } internal void RaiseDoWorkComplete(object sender, EventArgs e) { if (DoWorkComplete != null) { DoWorkComplete(this, null); } } public event EventHandler DoWorkComplete; } class SomeWidgetWorker : BaseWorker { public override void DoWork() { System.Threading.Thread.Sleep(2000); RaiseDoWorkComplete(this, null); } }

  • Wrong date with ruby Date.today and DateTime.now

    - by Rob
    I've installed ruby-1.8.6-p383 with RVM. System ruby is 1.9.1_p378-1 I'm getting the wrong date from Date.today and DateTime.now when using ruby 1.8.. Whereas Time.now is correct: irb(main):002:0> DateTime.now.to_s => "2126--1-10618T11:23:43+00:00" irb(main):004:0> Date.today.to_s => "2126--1-10618" irb(main):005:0> Time.now => Thu Jan 28 11:55:27 +0000 2010 All is well if I switch to ruby 1.9: irb(main):003:0> DateTime.now.to_s => "2010-01-28T11:58:51+00:00" irb(main):004:0> Date.today.to_s => "2010-01-28" irb(main):005:0> Time.now => 2010-01-28 11:59:05 +0000 Any advice on how to get DateTime to work properly in ruby 1.8 would be most appreciated!

  • routing mvc on the web

    - by generic_noob
    Hi, I was wondering if anyone could possibly provide me some advice on how i could improve the routing (and/or architecture) to each 'section' of my application. (I'm writing in PHP5, and trying to use strict MVC) Basically, I have a generic index page for the app, and that will spew out boilerplate stuff like jquery and the css etc. and it also generates the main navidation for the entire site, but i'm unsure about the best approach to connect the 'main menu' items(hyperlinks) with their associated controllers. Up until now I have been appending strings into the url and using a 'switch' statement to branch to the correct controller(and view) by extracting the strings back out of '$GET[]' to let it execute the code for the corrosponding action. for instance if i had a basic crud system for customer data, the url to edit a customers details would look like 'www.example.com/index.php?page=customer&action=edit&id=4'. I'm worried that there is a security concern by doing it this way, and i'm not sure of an alternative to branch the main 'index.php' file to the correct controller for each action once the user has clicked the link. Would it be better to use mod_rewrite to disguise the controllers names? or to create a similar system to the ASP MVC framework, where there is a seperate routing system where each url is filtered to get the associated controller? Cheers!

  • Observer Design Pattern - multiple event types

    - by David
    I'm currently implementing the Observer design pattern and using it to handle adding items to the session, create error logs and write messages out to the user giving feedback on their actions (e.g. You've just logged out!). I began with a single method on the subject called addEvent() but as I added more Observers I found that the parameters required to detail all the information I needed for each listener began to grow. I now have 3 methods called addMessage(), addStorage() and addLog(). These add data into an events array that has a key related to the event type (e.g. log, message, storage) but I'm starting to feel that now the subject needs to know too much about the listeners that are attached. My alternative thought is to go back to addEvent() and pass an event type (e.g. USER_LOGOUT) along with the data associated and each Observer maintains it's own list of event handles it is looking for (possibly in a switch statement), but this feels cumbersome. Also, I'd need to check that sufficient data had also been passed along with the event type. What is the correct way of doing this? Please let me know if I can explain any parts of this further. I hope you can help and see the problem I'm battling with.

  • Why notify listeners in a content provider query method?

    - by cbrulak
    Vegeolla has this blog post about content providers and the snippet below (at the bottom) with this line: cursor.setNotificationUri(getContext().getContentResolver(), uri); I'm curious as to why one would want to notify listeners about a query operation. Am I missing something? Thanks @Override public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) { // Uisng SQLiteQueryBuilder instead of query() method SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder(); // Check if the caller has requested a column which does not exists checkColumns(projection); // Set the table queryBuilder.setTables(TodoTable.TABLE_TODO); int uriType = sURIMatcher.match(uri); switch (uriType) { case TODOS: break; case TODO_ID: // Adding the ID to the original query queryBuilder.appendWhere(TodoTable.COLUMN_ID + "=" + uri.getLastPathSegment()); break; default: throw new IllegalArgumentException("Unknown URI: " + uri); } SQLiteDatabase db = database.getWritableDatabase(); Cursor cursor = queryBuilder.query(db, projection, selection, selectionArgs, null, null, sortOrder); // Make sure that potential listeners are getting notified cursor.setNotificationUri(getContext().getContentResolver(), uri); return cursor; }

  • Can this be done in 1 line?

    - by Angelo
    Can this be done in 1 line with PHP? Would be awesome if it could: $out = array("foo","bar"); echo $out[0]; Something such as: echo array("foo","bar")[0]; Unfortunately that's not possible. Would it be possible like this? So I can do this for example in 1 line: echo array(rand(1,100), rand(1000,2000))[rand(0,1)]; So let's say I have this code: switch($r){ case 1: $ext = "com"; break; case 2: $ext = "nl"; break; case 3: $ext = "co.uk"; break; case 4: $ext = "de"; break; case 5: $ext = "fr"; break; } That would be much more simplified to do it like this: $ext = array("com","nl","co.uk","de","fr")[rand(1,5)];

  • NSSegmentedControl -selectedSegment always returns 0

    - by SphereCat1
    I have an NSSegmentedControl with two segments set to "Select None" mode in Interface Builder. No matter what I try, I can't get -selectedSegment to return anything but 0, even though segment 0 is even disabled by default and can't possibly be selected. Here's the relevant function that gets called when you click any segment on the control: -(IBAction)changeStep:(id)sender { [stepContainer setHidden:TRUE]; [(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]] removeFromSuperview]; switch ([[navigationButton cell] selectedSegment]) { case 0: [wizard setStep:(NSInteger *)[wizard step]-1]; break; case 1: [wizard setStep:(NSInteger *)[wizard step]+1]; break; default: break; } //[[navigationButton cell] setSelected:FALSE forSegment:[navigationButton selectedSegment]]; if ([wizard step] > 0) { [wizard setStep:0]; [navigationButton setEnabled:FALSE forSegment:0]; } NSLog(@"%d", [wizard step]); [stepContainer addSubview:(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]]]; [stepContainer setHidden:FALSE withFade:TRUE]; } I've also tried using -isSelectedForSegment, but it has the same result. Any help you can provide would be awesome, I have no idea what I'm doing wrong. Thanks! SphereCat1

  • Handling Application Logic in Multiple AsyncTask onPostExecute()s

    - by stormin986
    I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }

  • App Crashes Loading View Controllers

  • Constructor Overloading

    - by Mark Baker
    Normally when I want to create a class constructor that accepts different types of parameters, I'll use a kludgy overloading principle of not defining any args in the constructor definition: e.g. for an ECEF coordinate class constructor, I want it to accept either $x, $y and $z arguments, or to accept a single array argument containg x, y and z values, or to accept a single LatLong object I'd create a constructor looking something like: function __construct() { // Identify if any arguments have been passed to the constructor if (func_num_args() > 0) { $args = func_get_args(); // Identify the overload constructor required, based on the datatype of the first argument $argType = gettype($args[0]); switch($argType) { case 'array' : // Array of Cartesian co-ordinate values $overloadConstructor = 'setCoordinatesFromArray'; break; case 'object' : // A LatLong object that needs converting to Cartesian co-ordinate values $overloadConstructor = 'setCoordinatesFromLatLong'; break; default : // Individual Cartesian co-ordinate values $overloadConstructor = 'setCoordinatesFromXYZ'; break; } // Call the appropriate overload constructor call_user_func_array(array($this,$overloadConstructor),$args); } } // function __construct() I'm looking at an alternative: to provide a straight constructor with $x, $y and $z as defined arguments, and to provide static methods of createECEFfromArray() and createECEFfromLatLong() that handle all the necessary extraction of x, y and z; then create a new ECEF object using the standard constructor, and return that Which option is cleaner from an OO purists perspective?

  • Behavior of <- NULL on lists versus data.frames for removing data

    - by Ananda Mahto
    Many R users eventually figure out lots of ways to remove elements from their data. One way is to use NULL, particularly when you want to do something like drop a column from a data.frame or drop an element from a list. Eventually, a user comes across a situation where they want to drop several columns from a data.frame at once, and they hit upon <- list(NULL) as the solution (since using <- NULL will result in an error). A data.frame is a special type of list, so it wouldn't be too tough to imagine that the approaches for removing items from a list should be the same as removing columns from a data.frame. However, they produce different results, as can be seen in the example below. ## Make some small data--two data.frames and two lists cars1 <- cars2 <- head(mtcars)[1:4] cars3 <- cars4 <- as.list(cars2) ## Demonstration that the `list(NULL)` approach works cars1[c("mpg", "cyl")] <- list(NULL) cars1 # disp hp # Mazda RX4 160 110 # Mazda RX4 Wag 160 110 # Datsun 710 108 93 # Hornet 4 Drive 258 110 # Hornet Sportabout 360 175 # Valiant 225 105 ## Demonstration that simply using `NULL` does not work cars2[c("mpg", "cyl")] <- NULL # Error in `[<-.data.frame`(`*tmp*`, c("mpg", "cyl"), value = NULL) : # replacement has 0 items, need 12 Switch to applying the same concept to a list, and compare the difference in behavior. ## Does not fully drop the items, but sets them to `NULL` cars3[c("mpg", "cyl")] <- list(NULL) # $mpg # NULL # # $cyl # NULL # # $disp # [1] 160 160 108 258 360 225 # # $hp # [1] 110 110 93 110 175 105 ## *Does* drop the `list` items while this would ## have produced an error with a `data.frame` cars4[c("mpg", "cyl")] <- NULL # $disp # [1] 160 160 108 258 360 225 # # $hp # [1] 110 110 93 110 175 105 The main questions I have are, if a data.frame is a list, why does it behave so differently in this scenario? Is there a foolproof way of knowing when an element will be dropped, when it will produce an error, and when it will simply be given a NULL value? Or do we depend on trial-and-error for this?

  • Programatically enable/disable menuBar buttons in Flex 4

    - by Hamid
    I have the following XML in my Flex4 (AIR) project that defines the start of my menu interface: <mx:MenuBar x="0" y="0" width="100%" id="myMenuBar" labelField="@label" itemClick="menuChange(event)"> <mx:dataProvider> <s:XMLListCollection> <fx:XMLList xmlns=""> <menu label="File"> <item label="New"/> <item label="Load"/> <item label="Save" enabled="false"/> </menu> <menu label="Help"> <item label="About"/> </menu> </fx:XMLList> </s:XMLListCollection> </mx:dataProvider> </mx:MenuBar> I am trying to find the syntax that will let me set the save button to enabled=true after a file has been loaded by clicking "Load", however I can't figure out the syntax, can someone make a suggestion please. Currently the way that button clicks are detected is by a Switch/Case testing the String result of the MenuEvent event.item.@label. Maybe this isn't the best way?

  • Weak hashmap with weak references to the values?

    - by Razor Storm
    I am building an android app where each entity has a bitmap that represents its sprite. However, each entity can be be duplicated (there might be 3 copies of entity asdf for example). One approach is to load all the sprites upfront, and then put the correct sprite in the constructors of the entities. However, I want to decode the bitmaps lazily, so that the constructors of the entities will decode the bitmaps. The only problem with this is that duplicated entities will load the same bitmap twice, using 2x the memory (Or n times if the entity is created n times). To fix this, I built a SingularBitmapFactory that will store a decoded Bitmap into a hash, and if the same bitmap is asked for again, will simply return the previously hashed one instead of building a new one. Problem with this, though, is that the factory holds a copy of all bitmaps, and so won't ever get garbage collected. What's the best way to switch the hashmap to one with weakly referenced values? In otherwords, I want a structure where the values won't be GC'd if any other object holds a reference to it, but as long as no other objects refers it, then it can be GC'd.

  • How to start/stop/restart jQuery animation

    - by Emin
    I have the following function that when I call displays a message to the user for a certain amount of time (5 secs in my case). During this "period" if I call the function again to display another message, practically it should hide, then re-appear with the new message for another 5 seconds. What happens with my code below, I call the function to display the message. Then, lets say on the 4th second, I call it again to display another message, the new message is displayed for 1 second. I need to somehow -reset- the time but can't figure out how. Tried stopping the animation, checking if the element was visible and hiding it if it was, and many other things. I believe the solution is a simple chaining issue but can't get it right. So any help would be appreciated! function display_message(msgType, message) { var elem = $('#ur_messagebox'); switch (msgType) { case 'confirm': elem.addClass('msg_confirm'); break; case 'error': elem.addClass('msg_error'); break; } elem.html(message); elem.show().delay(5000).fadeOut(1000); } thanks in advance...

  • How do I enable SVN menu in an editor window in Eclipse?

    - by Jordan Reiter
    The SVN menu is disabled whenever I'm in an edit window; it's enabled when I'm in the Navigator or similar file browsing windows. I'd like to have the SVN menu enabled while the editor window is open in order so that I can set up a key binding and commit while editing the document rather than having to switch over to the navigation view to commit a file. This is Eclipse 3.5 using Eclipse's Subversion Connectors plugin. This may be related: I had to do a reinstall of eclipse and a fair number of the keybindings no longer work the way the once did. In addition, many keystrokes now only work in windows only instead of windows and dialogs (specifically select all, copy, and paste). If these problems are related and there's an easy way to repair or refresh my keybindings without having to start over completely that would be great. Clarification I know how to set up key mappings. That's not a problem. I have them set up. The problem is that the SVN menu is disabled in the editor pane. I can access the SVN menu from the Navigator or similar panes, and I've set up the keymappings exactly the way I want them. They just aren't working in all contexts.

Issue, i included in my script a way to return all others to there default (only one should be selected) now, how can I fix this issue that I seem unable to correct as I can select multiple of them ** USERS can switch ** The last part of the script that is the issue. Thanks $(document).ready(function() { $('.form_sub').hide(); $('.theader').addClass('active'); $('.theader_t').click(function() { $('.form_header').show(); $('.form_sub').hide(); $('.theader').addClass('active'); $('.sub_theader').removeClass('active'); }); $('.sub_theader_t').click(function() { $('.form_header').hide(); $('.form_sub').show(); $('.theader').removeClass('active'); $('.sub_theader').addClass('active'); }); $('.top_head_img').click(function() { $(this).css({ position: 'relative', bottom: '20px' }).siblings().css( 'bottom', '0' ); }); }); <ul class="top_head"> <li> <a href="javascript:void(0)" onClick="selectPic5('top');"><img src="custom/images/top2.jpg" alt="Left" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('center');"><img src="custom/images/mid2.jpg" alt="Center" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('bottom');"><img src="custom/images/bot2.jpg" alt="Right" border="0" class="top_head_img"/></a> </li> </ul>

  • Entangled text boxes

    - by user38329
    Hi StackOverflow, A mere Windows textbox greatly surprised me today. I have two unrelated text boxes inside an application. I can type in either text box and switch the focus by clicking on them. Then happens some event X, which I can't describe here for reasons given below. After this event happens, the two text boxes become "entangled" in an almost quantum way. Say, text box A was focused before X happened. When I click text box B to type in some text, the new text appears in text box A, whereas the blinking cursor happily moves along in text box B through the void, as if the text were there. No amount of clicking on either text boxes can resolve this. The cursor will always remain in B, whereas the text will always go to A. Message spying reveals that after the event X, the text boxes lose the ability to lose or gain focus. When I click on B, WM_LOSE_FOCUS does not come to A, and WM_SET_FOCUS does not come to B. (The rectangles and visibility of the boxes are OK.) The same thing happens in Windows XP and Windows 7. Now, event X: it's a big event in a third-party UI library which I cannot reverse-engineer in a timely manner. (Namely, docking a pane in wxAUI.) I am sure that this behavior is the result of incorrect WinAPI calls to the text boxes (garbage in - garbage out). I would like to know what could possibly cause such "textbox trip" to know where to start looking for the bug. Thanks!

  • Noob - Cycle through stored names and skip blanks

    - by ActiveJimBob
    NOOB trying to make my code more efficient. On scroll button push, the function 'SetName' stores a number to integer 'iName' which is index against 5 names stored in memory. If a name is not set in memeory, it skips to the next. The code works, but takes up a lot of room. Any advice appreciated. Code: #include <string.h> int iName = 0; int iNewName = 0; BYTE GetName () { return iName; } void SetName (int iNewName) { while (iName != iNewName) { switch (byNewName) { case 1: if (strlen (memory.m_nameA) == 0) new_name++; else iName = iNewName; break; case 2: if (strlen (memory.m_nameB) == 0) new_name++; else iName = iNewName; break; case 3: if (strlen (memory.m_nameC) == 0) new_name++; else iName = iNewName; break; case 4: if (strlen (memory.m_nameD) == 0) new_name++; else iName = iNewName; break; case 5: if (strlen (memory.m_nameE) == 0) new_name++; else iName = iNewName; break; default: iNewName = 1; break; } // end of case } // end of loop } // end of SetName function void main () { while(1) { if (Button_pushed) SetName(GetName+1); } // end of infinite loop } // end of main
