  • What VS Projecttype for Model and Database?

    - by Tim
    Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks

  • Anyone using IronPython in a production application?

    - by Scott P
    I've been toying with the idea of adding IronPython for extending a scientific application I support. Is this a good or horrible idea? Are there any good examples of IronPython being used in a production application. I've seen Resolver, which is kind of cute. Are there any other apps out there? What I don't get is this. Is it any easier to use IronPython than to just use something like code DOM to create script like extensibility in your application? Anyone have some horror stories or tales of glorious success with IronPython / IronRuby?

  • watchpoint in GDB

    - by Tim
    Hi, If I set a watchpoint for a variable local to the current scope, it will be auto deleted when going out of the scope. Is there any way to set it once and keep it auto alive whenever entering the same scope? Is there anyway to set conditional watchpoint, like "watch var1 if var1==0"? In my case, the condition does't work. gdb stops whenever var1's value is changed, instead of untill "var1==0" is true. My gdb is GNU gdb 6.8-debian. Thanks and regards!

  • Do I need to include the 'this' when using a property name in a closure?

    - by Scott Whitlock
    I'm using a list of Actions to store an undo history for an object. Let's say I have a property of my object called myChildObject and it's being changed, so I want to store the undo action where I would set it back to it's current value: public class Class1 { public Class1() { } private readonly List<Action> m_undoActions = new List<Action>(); private SomeObject myChildObject { get; set; } public void ChangeState(SomeObject newChildObject) { // copies the reference SomeObject existingObject = myChildObject; m_undoActions.Add(() => myChildObject = existingObject); myChildObject = newChildObject; } } Looking at the lambda expression, existingObject is a local variable, so it's using a closure to pass a reference to that variable, but what about the property myChildObject? Do I need to use 'this' to preface it? Do I need to make a copy of the 'this' reference to a local variable first? Thanks for helping me understand this closure stuff.

    - by scott
    void main () { int c; signal (SIGINT, Handle); while (( c = getchar()) != '\n' ); return(); } void Handle(signum) { signal {SIGINT, Handle); printf ("beep \n"); } I thought it would print 'beep' until any key has been pressed but the method call is outside the loop? :S

  • Link User32 with gcc

    - by Tim Cooper
    I have a C program which has a function call that is defined in windows.h (which I have included), however, when I try and compile it with gcc, I get the error: warning: implicit declaration of function `LockWorkStation' I looked at the MSDN documentation and I see that this function is the User32 library file, and I was wondering how I would go about linking that to my file.

  • Test For CSS3 Radial Gradient Vendor Syntax

    - by Scott Christopherson
    I'm having an issue where I'm trying to update the background gradient of an element with JavaScript based on values I specify. I tried this route: elem.style.backgroundImage = '-webkit-gradient(radial, '+x+' '+y+', 0, '+x+' '+y+', 800, from(#ccc), to(#333)), -moz-radial-gradient('+x+'px '+y+'px, circle cover, #ccc 0, #333 100%)'; Since Webkit and Gecko have two different syntaxes for CSS3 gradients, I need to specify both. However, the above code doesn't work. It works if I only have just the Gecko syntax or just the Webkit syntax, not both. I think you can check for CSS gradient support, but my question is, is there a way to check which syntax needs to be used without browser sniffing? Keep in mind that I need to set my gradients this way since the x and y coordinates of the gradient change dynamically. Hope this makes sense, thanks.

  • MS Access (2010) Enable Design View

    - by Tim GONELLA
    I downloaded the Access template below for doing a home inventory: http://office.microsoft.com/en-us/templates/results.aspx?qu=home%20inventory&ex=1&queryid=0d245f2a%2Dacdc%2D4161%2D92c8%2D8ba16a52ab32&AxInstalled=1&c=0#ai:TC101918100| The design view is not visible, which is a bit of a nuisance. Things I've tried: 1) In options/options/current database/ the check boxes (enable layout view & enable design changes for tables in Datasheet view) are both greyed out. 2) I've unblocked the file using Right-Click-Properties. 3) I've tried copying/exporting the objects to another database. But can only copy/export the tables. 4) I've tried holding shift when opening the DB. 5) Enabling all trust permissions etc. None of these work Does anybody have any suggestions. (I'm using Office 2010) Thanks

  • Consecutive Tables in Latex

    - by Tim
    Hi, I wonder how to place several tables consecutively in Latex? The page with the text right before the first table has a little space but not enough for the first table, so the first table is to be placed on the top of the next page, although I use "\begin{table}[!h]" for it. The second table does not fit into the place in the rest of the page of the first table, so I think I might use longtable for it to span the rest of the page and the top of the next page. Similarly, I use longtable for the third table. The latex code is as follows: ... % some text \begin{table}[!h] \caption{Table 1. \label{tab:1}} \begin{center} \begin{tabular}{c c} ... \end{tabular} \end{center} \end{table} \begin{center} \begin{longtable}{ c c } \caption{Table 2. \label{tab:2}}\\ ... \end{longtable} \end{center} \begin{center} \begin{longtable}{ c c } \caption{Table 3. \label{tab:3}}\\ ... \end{longtable} \end{center} ... % some text In the compiled pdf file it turns out that the order of the tables is messed up. The first table is placed behind the second and third one, and the second one spans the page with text before the tables and the next page with the third one following it. I would like to know how I can make the three tables appear consecutively in order, and there are no space left blank between them and between the text and the tables? Or if what I hope is not possible, what is the best strategy then? Thanks and regards! EDIT: Removing [!h] does not make improvement, the first table is still behind the second and the third.

  • Selecting a radio button when a dropdown value changes

    - by Tim F.
    My setup is something like this: radiobutton1 - selection1 radiobutton2 - selection2 textinput1 I want radiobutton1 to be selected whenever selection1 is changed, and I want radiobutton2 to be selected whenever either selection2 or textinput1 is changed. There has to be a simple javascript solution here... I just can't find it. Here's my actual code ("$semopt" is a string holding the html code for the options on the first selection input): <input type='radio' name='semester' value='existing'/>Existing semester: <select name='sem_id'">$semopt </select><br/> <input type='radio' name='semester' value='new'/>New Semester: <select name='sem_name'"> <option value='Fall'>Fall</option> <option value='Spring'>Spring</option> </select> <input name='sem_year' value='$thisyear' size='5'"/><br/>

  • How can I force a ListView with a custom panel to re-measure when the ListView width goes below the

    - by Scott Whitlock
    Sorry for the long winded question (I'm including background here). If you just want the question, go to the end. I have a ListView with a custom Panel implementation that I'm using to implement something similar to a WrapPanel, but not quite. I'm overriding the MeasureOverride and ArrangeOverride methods in the custom panel. If I do the naive implementation of a WrapPanel in the MeasureOverride method it doesn't work when the ListView is resized. Let's say the custom panel does a measure and the constraint is a width of 100 and let's say I have 3 items that are 40 wide each. The naive approach is to return a size of 80,80 but when I resize the window that the ListView is in, down to say 75, it just turns on the horizontal scrollbar and never calls measure or arrange again (it does keep measuring and arranging if the width is greater than 80). To get around this, I hard coded the measurement to only have a width of the widest item. Then in the arrange, it gives me more space than I asked for and I use as much horizontal space as I can before wrapping. If I resize the window smaller than the smallest item in the ListView, then it turns on the scrollbar, which is great. Unfortunately this is causing a big problem when I have one of these ListViews with a custom panel nested inside of another one. The outside one works ok, but I can't get the inside one to "take as much as it needs". It always sizes to the smallest item, and the only way around it is to set the MinWidth to be something greater than zero. Anyway, stepping back for a second, I think the real way to fix this is to go back to the Naive implementation of the WrapPanel but force it to re-measure when the ListView width goes below the Size I previously returned as a measurement. That should solve my problem with the nested one. So, that's my question: I have a ListView with a custom panel If I return a measurement width on the panel and the ListView is resized to less than that width, it stops calling MeasureOverride How can I get it to continue calling MeasureOverride?

  • copy an element as HTML to clipboard

    - by Brian Scott
    I've managed to write some jQuery to find an element and copy it's html to the clipboard (ie only). The problem is that when I paste this into a rich text box area in sharepoint it pastes the HTML as text only. How do i replicate the user action of highlighting a link on a page and pressing copy. When I do this manually and then paste the clipboard contents the rich text area realises that it is markup and replicates the link as an anchor in the text content.

  • Performance optimization for SQL Server: decrease stored procedures execution time or unload the ser

    - by tim
    We have a web service which provides search over hotels. There is a problem with performance: a single request to the service takes around 5000 ms. Almost all of the time is spent in database by executing storing procedures. During the request our server (mssql2008) consumes ~90% of the processor time. When 2 requests are made in parallel the average time grows and is around 7000 ms. When number of request is increasing, the average time of response is increasing as well. We have 20-30 requests per minute. Which kind of optimization is the best in this case having in mind that the goal is to provide stable response time for the service: 1) Try to decrease the stored procedures execution time 2) Try to find the way how to unload the server It is interesting to hear from people who deal with booking sites.

  • qtruby, QUiLoader and respond_to?

    - by Tim Sylvester
    I'm writing a simple Qt4 application in Ruby (using qtruby) to teach myself both. Mostly it has gone well, but in trying to use Ruby's "duck typing" I've run into a snag; respond_to? doesn't seem to reflect reality. irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'Qt4' => true irb(main):003:0> require 'qtuitools' => true irb(main):004:0> Qt::Application.new(ARGV) => #<Qt::Application:0xc3c9a08 objectName="ruby"> irb(main):005:0> file = Qt::File.new("dlg.ui") { open(Qt::File::ReadOnly) } => #<Qt::File:0xc2e1748 objectName=""> irb(main):006:0> obj = Qt::UiLoader.new().load(file, nil) => #<Qt::Dialog:0xc2bf650 objectName="dlg", x=0, y=0, width=283, height=244> irb(main):007:0> obj.respond_to?('children') => false irb(main):008:0> obj.respond_to?(:children) => false irb(main):009:0> obj.children => [#<Qt::FormInternal::TranslationWatcher:0xc2a1980 objectName="">, ... As you can see, when I check to ensure that the object I get back from loading the UI file has a children accessor I get false. If call that accessor, however, I get an array rather than a NoMethodError. So, is this a bug or have I incorrectly understood respond_to?? This looks like the problem described here, but I thought I would get an expert opinion before filing a bug against the project.

  • Why are my Opteron cores running at only 75% capacity each? (25% CPU idle)

    - by Tim Cooper
    We've just taken delivery of a powerful 32-core AMD Opteron server with 128Gb. We have 2 x 6272 CPU's with 16 cores each. We are running a big long-running java task on 30 threads. We have the NUMA optimisations for Linux and java turned on. Our Java threads are mainly using objects that are private to that thread, sometimes reading memory that other threads will be reading, and very very occasionally writing or locking shared objects. We can't explain why the CPU cores are 25% idle.

I had trouble finding a clear explanation of what 'top' means by "idle" versus "wait", but I get the impression that "idle" means "no more threads that need to be run" but this doesn't make sense in our case. We're using a "Executors.newFixedThreadPool(30)". There are a large number of tasks pending and each task lasts for 10 seconds or so. I suspect that the explanation requires a good understanding of NUMA. Is the "idle" state what you see when a CPU is waiting for a non-local access? If not, then what is the explanation?

  • Microsoft Word Document Controls not accepting carriage returns

    - by Scott
    So, I have a Microsoft Word 2007 Document with several Plain Text Format (I have tried Rich Text Format as well) controls which accept input via XML. For carriage returns, I had the string being passed through XML containing "\r\n" when I wanted a carriage return, but the word document ignored that and just kept wrapping things on the same line. I also tried replacing the \r\n with System.Environment.NewLine in my C# mapper, but that just put in \r\n anyway, which still didn't work. Note also that on the control itself I have set it to "Allow Carriage Returns (Multiple Paragrpahs)" in the control properties. This is the XML for the listMapper <Field id="32" name="32" fieldType="SimpleText"> <DataSelector path="/Data/DB/DebtProduct"> <InputField fieldType="" path="/Data/DB/Client/strClientFirm" link="" type=""/> <InputField fieldType="" path="strClientRefDebt" link="" type=""/> </DataSelector> <DataMapper formatString="{0} Account Number: {1}" name="SimpleListMapper" type=""> <MapperData> </MapperData> </DataMapper> </Field> Note that this is the listMapper C# where I actually map the list (notice where I try and append the system.environment.newline) namespace DocEngine.Core.DataMappers { public class CSimpleListMapper:CBaseDataMapper { public override void Fill(DocEngine.Core.Interfaces.Document.IControl control, CDataSelector dataSelector) { if (control != null && dataSelector != null) { ISimpleTextControl textControl = (ISimpleTextControl)control; IContent content = textControl.CreateContent(); CInputFieldCollection fileds = dataSelector.Read(Context); StringBuilder builder = new StringBuilder(); if (fileds != null) { foreach (List<string> lst in fileds) { if (CanMap(lst) == false) continue; if (builder.Length > 0 && lst[0].Length > 0) builder.Append(Environment.NewLine); if (string.IsNullOrEmpty(FormatString)) builder.Append(lst[0]); else builder.Append(string.Format(FormatString, lst.ToArray())); } content.Value = builder.ToString(); textControl.Content = content; applyRules(control, null); } } } } } Does anybody have any clue at all how I can get MS Word 2007 (docx) to quit ignoring my newline characters??

  • Display using QtWebKit, whilst parsing xml

    - by Beren Scott
    I wish to use QtWebKit to load a url for display, but, that's the easy part, I can do that. What I wish to do is record / log xml as I go. My attention here is to record and database certain details on the fly, by recording those details. My problem is, how to do this all on the fly, without requesting the same url from the server twice, once for the xml, and the second time to view the url. My hope here, is to implement a very fast way of recording set data as the user passes over it. Take for example, rather then have to type out details displayed by a website, I wish to have those details chucked into a database as I the user views the website. Now, I am using QtWebKit, and I have everything pretty much solved viewing wise. I have a loadUrl() routine which calls load(url) inside the qwebview.h The problem is, how do I piggyback xml parsing on top of this?
