  • VB.NET: how to require CheckedListBox to have at least one item selected in WinForms

    - by Craig Johnston
    With the CheckListBox in VB.NET in VS2005, how would you make it compulsory that at least one item is selected? Can you select one of the items at design time to make it the default? EDIT: How can I make it so the last item the user tries to uncheck is the one that stays checked? So it's like the user tries to uncheck the only checked item but can't because it checks back straightaway.

  • LINQ-to-SQL IN/Contains() for Nullable<T>

    - by Craig Walker
    I want to generate this SQL statement in LINQ: select * from Foo where Value in ( 1, 2, 3 ) The tricky bit seems to be that Value is a column that allows nulls. The equivalent LINQ code would seem to be: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value) select foo; This, of course, doesn't compile, since foo.Value is an int? and values is typed to int. I've tried this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); IEnumerable<int?> nullables = values.Select( value => new Nullable<int>(value)); var myFoos = from foo in foos where nullables.Contains(foo.Value) select foo; ...and this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value.Value) select foo; Both of these versions give me the results I expect, but they do not generate the SQL I want. It appears that they're generating full-table results and then doing the Contains() filtering in-memory (ie: in plain LINQ, without -to-SQL); there's no IN clause in the DataContext log. Is there a way to generate a SQL IN for Nullable types?

  • Debugging SQL Server Slowness: Same Database, Different Servers

    - by Craig Walker
    For a while now we've been having anecdotal slowness on our newly-minted (VMWare-based) SQL Server 2005 database servers. Recently the problem has come to a head and I've started looking for the root cause of the issue. Here's the weird part: on the stored procedure that I'm using as a performance test case, I get a 30x difference in the execution speed depending on which DB server I run it on. This is using the same database (mdf) and log (ldf) files, detached, copied, and reattached from the slow server to the fast one. This doesn't appear to be a (virtualized) hardware issue: he slow server has 4x the CPU capacity and 2x the memory as the fast one. As best as I can tell, the problem lies in the environment/configuration of the servers (either operating system or SQL Server installation). However, I've checked a bunch of variables (SQL Server config options, running services, disk fragmentation) and found nothing that has made a difference in testing. What things should I be looking at? What tools can I use to investigate why this is happening?

  • Issue with Multiple ModalPopups, ValidationSummary and UpdatePanels

    - by Aaron Hoffman
    I am having an issue when a page contains multiple ModalPopups each containing a ValidationSummary Control. Here is the functionality I need: A user clicks a button and a Modal Popup appears with dynamic content based on the button that was clicked. (This functionality is working. Buttons are wrapped in UpdatePanels and the partial page postback calls .Show() on the ModalPopup) "Save" button in ModalPopup causes client side validation, then causes a full page postback so the entire ModalPopup disappears. (ModalPopup could disappear another way - the ModalPopup just needs to disappear after a successful save operation) If errors occur in the codebehind during Save operation, messages are added to the ValidationSummary (contained within the ModalPopup) and the ModalPopup is displayed again. When the ValidationSummary's are added to the PopupPanel's, the ModalPopups no longer display correctly after a full page postback caused by the "Save" button within the second PopupPanel. (the first panel continues to function correctly) Both PopupPanels are displayed, and neither is "Popped-Up", they are displayed in-line. Any ideas on how to solve this?

  • Visual Studio Debugging Issue

    - by Aaron M
    Seeing an issue when debugging in Visual Studio. All of the values under watch, and in the hover over window show up incorrectly. the only values that show properly, are values that are local to the method I am currently stepping through. For example the watch value for 'this' when debugging shows the following under value 0x00000000ffac0388 { btnBack=0x00000000ffaccf20 btnReply=0x00000000ffacd200 btnForward=0x00000000ffacd420...} some other variables show this, even though the variable is there. error: 'this.foo' does not exist The machine recently had windows 7 64 installed, since then this problem has occured. Visual studio has been reinstalled on this machine, and we verified that the settings in visual studio were exactly the same as a different PC that is the same machine and config.

  • How do I implement google maps yelp.com style?

    - by Craig
    I have multiple locations (20+ per page) that need to be mapped on a single map. I would like to click on a link for the location that is not dynamically generated (for SEO purposes) that would open the info window for the respective marker on the map. Behavior should mimic http://maptheburg.com/ - but this map has the sidebar links dynamically generated. Yelp.com is the only site I have seen so far that manages to implement the Google Maps API with unobtrusive JavaScript.

  • IE8 developer tools missing some styles

    - by Craig Warren
    Hi, I'm having some problems with some CSS properties in IE8. I've tested my site in IE7, Chrome and Firefox and they work fine but IE8 is having some layout issues. I inspect the developer tool option on ie8 and I've noticed that some of the properties I set in CSS are being ignored by ie8. For example: #header { position: relative; padding: 20px; height: 100px; background:url(header.png); } In this header IE8 ignored the height property: If I inspect the element in developer tools it is missing that property and it's crushed into another line: background:url;HEIGHT: 100PX The same thing happens for floats too: #logon { float: left; text-align:right; width:20%; height: 40px; padding-left: 0px; padding-right:7px; border:0; margin:0; background: url(navgradient.gif); } This ignores the float value: background: url(navgradient.gif); FLOAT:left; What is happening here and how can I fix it?

  • Algorithm for nice graph labels for time/date axis?

    - by Aaron
    Hello, I'm looking for a "nice numbers" algorithm for determining the labels on a date/time value axis. I'm familar with Paul Heckbert's Nice Numbers algorithm (http://tinyurl.com/5gmk2c). I have a plot that displays time/date on the X axis and the user can zoom in and look at a smaller time frame. I'm looking for an algorithm that picks nice dates to display on the ticks. For example: Looking at a day or so: 1/1 12:00, 1/1 4:00, 1/1 8:00... Looking at a week: 1/1, 1/2, 1/3... Looking at a month: 1/09, 2/09, 3/09... The nice label ticks don't need to correspond to the first visible point, but close to it. Is anybody familar with such an algorithm? Thanks

  • Are PyArg_ParseTuple() "s" format specifiers useful in Python 3.x C API?

    - by Craig McQueen
    I'm trying to write a Python C extension that processes byte strings, and I have something basically working for Python 2.x and Python 3.x. For the Python 2.x code, near the start of my function, I currently have a line: if (!PyArg_ParseTuple(args, "s#:in_bytes", &src_ptr, &src_len)) ... I notice that the s# format specifier accepts both Unicode strings and byte strings. I really just want it to accept byte strings and reject Unicode. For Python 2.x, this might be "good enough"--the standard hashlib seems to do the same, accepting Unicode as well as byte strings. However, Python 3.x is meant to clean up the Unicode/byte string mess and not let the two be interchangeable. So, I'm surprised to find that in Python 3.x, the s format specifiers for PyArg_ParseTuple() still seem to accept Unicode and provide a "default encoded string version" of the Unicode. This seems to go against the principles of Python 3.x, making the s format specifiers unusable in practice. Is my analysis correct, or am I missing something? Looking at the implementation for hashlib for Python 3.x (e.g. see md5module.c, function MD5_update() and its use of GET_BUFFER_VIEW_OR_ERROUT() macro) I see that it avoids the s format specifiers, and just takes a generic object (O specifier) and then does various explicit type checks using the GET_BUFFER_VIEW_OR_ERROUT() macro. Is this what we have to do?

  • Java2D OpenGL Hardware Acceleration Doesn't Work

    - by Aaron
    It doesn't work with OpenGL with even the simplest of programs. Here is what I am doing.. java -Dsun.java2d.opengl=True -jar Java2Demo.jar (Java2Demo.jar is usually included with the JDK..) The text output is: OpenGL pipeline enabled for default config on screen 0 When I don't pass in the above VM argument things work fine (but slowly). When I do pass in the above argument nothing shows up... If I move the window around it captures whatever image it was on top of and jumbles it into nonsense. I'm running Windows XP Pro SP3 (Microsoft Windows XP [Version 5.1.2600]) (under Parallels on OS X 10.5.8) I used "Geeks3D GPU Caps Viewer" to tell me I have Open GL version: 2.0 NVIDIA-1.5.48 I have tried this with two version of the JVM.

  • How to embed multiple tags in Rails routes, like Stackoverflow.

    - by Craig
    When one selects a Tag on stackoverflow, it is added to the end of the Url. Add a second Tag and it is add to the end of the Url after the first Tag, with a '+' delimiter. For example, http://stackoverflow.com/questions/tagged/ruby-on-rails+best-practices. How is this implemented? Is this a routing enhancement or some logic contained in the TagsController? Finally, how does one 'extract' these Tags for filtering (assuming that they are not in the params[] array)?

  • Scrolling with two fingers with a UIScrollView

    - by Craig
    I have an app where my main view accepts both touchesBegan and touchesMoved, and therefore takes in single finger touches, and drags. I want to implement a UIScrollView, and I have it working, but it overrides the drags, and therefore my contentView never receives them. I'd like to implement a UIScrollview, where a two finger drag indicates a scroll, and a one finger drag event gets passed to my content view, so it performs normally. Do I need create my own subclass of UIScrollView? Here's my code from my appDelegate where I implement the UIScrollView. @implementation MusicGridAppDelegate @synthesize window; @synthesize viewController; @synthesize scrollView; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch //[application setStatusBarHidden:YES animated:NO]; //[window addSubview:viewController.view]; scrollView.contentSize = CGSizeMake(720, 480); scrollView.showsHorizontalScrollIndicator = YES; scrollView.showsVerticalScrollIndicator = YES; scrollView.delegate = self; [scrollView addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [scrollView release]; [window release]; [super dealloc]; }

  • Open a new browser window, or set focus to an existing browser

    - by Craig Myles
    Hi, I'm using code similar to the following: http://blog.flexexamples.com/2007/08/29/launching-new-browser-windows-from-flex/ I have a Flex app running in AIR, and when I click on a URL it opens a new tab in my existing browser. In addition to this the focus doesn't set to the browser. What this means is that I'm not aware of the URL opening in the browser unless I actually change focus from the app to the browser. Is it possible to open a brand new spanking browser, or change focus to the browser so its really obvious to the user? Thanks.

  • Add querystring parameters to link_to

    - by Craig
    I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

  • LINQ to SQL vs Entity Framework for an app with a future SQL Azure version

    - by Craig L
    I've got a vertical market Dot Net Framework 1.1 C#/WinForms/SQL Server 2000 application. Currently it uses ADO.Net and Microsoft's SQLHelper for CRUD operations. I've successfully converted it to Dot Net Framework 4 C#/WinForms/ SQL Server 2008. What I'd like to do is also offer my customers the ability to use SQL Azure as a backend storage for their data instead of local/LAN SQL Server. If I know SQL Azure is in my application's future, should I: A. Switch to LINQ to SQL B. Swith to Entity Framework C. Stick with ADO.Net and SQLHelper Thanks !

  • Can't find how to import as one object or how to merge

    - by Aaron
    I need write a script in blender that creates some birds which fly around some obstacles. The problem is that I need to import a pretty large Collada model (a building) which consists of multiple objects. The import works fine, but the the building is not seen as 1 object. I need to resize and move this building, but I can only get the last object in the building (which is a camera)... Does anyone know how to merge this building in 1 object, group, variable... so I can resize and move it correctly? Part of the code I used: bpy.ops.wm.collada_import(filepath="C:\\Users\\me\\building.dae") building= bpy.context.object building.scale = (100, 100, 100) building.name = "building"

  • Database-independant SQL String Concatenation in Rails

    - by Craig Walker
    I want to do a database-side string concatenation in a Rails query, and do it in database-independent way. SQL-92 specifies double-bar (||) as the concatenation operator. Unfortunately it looks like MS SQL Server doesn't support it; it uses + instead. I'm guessing that Rails' SQL grammar abstraction has solved the db-specific operator problem already. If it does exist, how do I use it?

  • 2D Ball Collisions with Corners

    - by Aaron
    I'm trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity for a vertical wall or the Y-velocity for a horizontal wall. The problem is that the ball can also collide with the corners of the walls, where a horizontal wall meets with a vertical wall. I have already figured out how to detect when a collision with a corner is occurring. My question is how the ball should react to this collision--that is, how its X and Y velocities will change as a result. Here's a list of what I already know or know how to find: *The X and Y coordinates of the ball's center during the frame when a collision is detected *The X and Y components of the ball's velocity *The X and Y coordinates of the corner *The angle between the ball's center and the corner *The angle in which the ball is traveling just before the collision *The amount that the ball is overlapping the corner when the collision is detected I'm guessing that it's best to pretend that the corner is an infinitely small circle, so I can treat a collision between the ball and that circle as if the ball were colliding with a wall that runs tangent to the circles at the point of collision. It seems to me that all I need to do is rotate the coordinate system to line up with this imaginary wall, reverse the X component of the ball's velocity under this system, and rotate the coordinates back to the original system. The problem is that I have no idea how to program this. By the way, this is an ideal simulation. I'm not taking anything like friction or the ball's rotation into account. I'm using Objective-C, but I'd really just like a general algorithm or some advice. Many thanks if anyone can help!
