  • Is .NET support for Win32 Code Interop?

    - by Usman
    Hello, I need to InterOp Win32 code (unmanaged Win32 DLL's and Exe) completely with .NET. I need to call Win32 unmanaged code(DLL exported functions) at runtime i.e (knowing the types of data types in Win32 signatures and need to pass data according to that type at runtime). This is 100% possible in case of COM. You can convert COM unmanaged code to managed assemblies using tlbimp.exe and use now reflection API to work with those managed types(actual were unmanaged types now converted managed using tlbimp). But same functionality I need to get in terms of Win32(i.e) in .NET framework. How?? I know MS provided Export table reading API ..but I couldn't find exact API for InterOp of Win32 unmanaged code Regards

  • EntityFramework EntityState and databinding along with INotifyPropertyChanged

    - by OffApps Cory
    Hello, all! I have a WPF view that displays a Shipment entity. I have a textblock that contains an asterisk which will alert a user that the record is changed but unsaved. I originally hoped to bind the visibility of this (with converter) to the Shipment.EntityState property. If value = EntityState.Modified Then Return Visibility.Visible Else Return Visibility.Collapsed End If The property gets updated just fine, but the view is ignorant of the change. What I need to know is, how can I get the UI to receive notification of the property change. If this cannot be done, is there a good way of writing my own IsDirty property that handles editing retractions (i.e. if I change the value of a property, then change it back to it's original it does not get counted as an edit, and state remains Unchanged). Any help, as always, will be greatly appreciated. Cory

    - by danwoods
    Hello all, I 'm relatively new to git and and having some problems early on. I've made several commits, but when I try to push them I get a response that says everything is up-to-date. I feel like my problem is the same on listed in this question, but it recommends the following: $ git log -1 # note the SHA-1 of latest commit $ git checkout master # reset your branch head to your previously detached commit $ git reset --hard <commit-id> What exactly will "checking out the master" do? I just don't want to lose the changes I've made... screenshot of gitk:

  • Silverlight TabItem template not working correctly

    - by Savvas Sopiadis
    Hello everybody! In a SL4 application i need to restyle my TabItems (actually add a button in the header). So i took the TabItem's control template from here and added the functionality i wanted. This seems to work fine, (i could dynamically add tabitems) with one exception: i think this posted control template is behaving somehow "arbitrary": every time the mouse hoovers over a non selected TabItem header, this gets selected WHITHOUT clicking!! (afaik this is not the default behavior: the user user has to click a header to make this tabitem the selected one). I tried to find why it is behaving like this, with no luck! Is there someone who can enlighten my darkness??? Thanks in advance!

  • F# performance in scientific computing

    - by aaa
    hello. I am curious as to how F# performance compares to C++ performance? I asked a similar question with regards to Java, and the impression I got was that Java is not suitable for heavy numbercrunching. I have read that F# is supposed to be more scalable and more performant, but how is this real-world performance compares to C++? specific questions about current implementation are: How well does it do floating-point? Does it allow vector instructions how friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? does it have capacity for distributed memory processors, for example Cray? what features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Thanks

  • Programmatically Setting Text Shadow Properties

    - by Ben Gribaudo
    Hello, PowerPoint has two kinds of shadows--shape and text. Shape shadows may be set by right-clicking on a shape (including a text box), choosing Format Text, then selecting Shadow or using VBA via the Shadow property on each shape: For Each Slide In ActivePresentation.Slides For Each Shape In Slide.Shapes Shape.Shadow.Size = 100 'etc Next Next How do I set text shadow's properties using VBA? In the UI, these may be accessed by right-clicking on text, choosing Format Text Effect, then selecting Shadow. I've done a bit of digging online and have been unable to find where these properties may be accessed via PowerPoint's VBA API. Thank you, Ben

  • Reusing a PreparedStatement multiple times

    - by Steel Plume
    Hello, in the case of using PreparedStatement with a single common connection without any pool, can I recreate an instance for every dml/sql operation mantaining the power of prepared statements? I mean: for (int i=0; i<1000; i++) { PreparedStatement preparedStatement = connection.prepareStatement(sql); preparedStatement.setObject(1, someValue); preparedStatement.executeQuery(); preparedStatement.close(); } instead of: PreparedStatement preparedStatement = connection.prepareStatement(sql); for (int i=0; i<1000; i++) { preparedStatement.clearParameters(); preparedStatement.setObject(1, someValue); preparedStatement.executeQuery(); } preparedStatement.close(); my question arises by the fact that I want to put this code into a multithreaded environment, can you give me some advice? thanks

  • Run a shell command with arguments from powershell script

    - by Mike Weerasinghe
    Hello, I need to extract and save a some tables from a remote SQL database using bcp. I would like to write a powershell script to invoke bcp for each table and save the data. So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead. This must be something really easy that I am not getting. #commands bcp database.dbo.tablename out c:\temp\users.txt -N -t, -U uname -P pwd -S <servername> $bcp_path = "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\bcp.exe" $serverinfo =@{} $serverinfo.add('table','database.dbo.tablename') $serverinfo.add('uid','uname') $serverinfo.add('pwd','pwd') $serverinfo.add('server','servername') $out_path= "c:\Temp\db\" $args = "$($serverinfo['table']) out $($out_path)test.dat -N -t, -U $($serverinfo['uid']) -P $($serverinfo['pwd']) -S $($serverinfo['server'])" #this is the part I can't figure out & $bcp_path $args

  • jquery autocomplete filtering

    - by eidylon
    Hello all, I have a page, which uses jQuery Autocomplete on the second two textboxes (investigator and institution). It is getting the data fine, and displaying it, but for some reason it is not filtering the list of data as i continue to type. Anyone know why? Is there something i need to do to turn this on? According to the jQuery site, the only options to the autocomplete initializer are delay, minLength and source. Thanks in advance! I'm using jQ v1.4.1 and jQui v.1.8rc1. Below is the code which I am calling on $(document).ready(). function hookUpAutoCompletes() { $('table#params input[name=sinvestigator]').autocomplete({ source: "json-investigators.asp", minLength: 2 }) $('table#params input[name=sinstitution]').autocomplete({ source: "json-institutions.asp", minLength: 2 }) }

  • Anti-aliasing not working when resizing a UIWebView

    - by nickcartwright
    I'd like to add a Web View to my app at 60% scale (like seen in Safari in the browse other windows view): Notice how the content looks nice and Aliased! If I try and add the same Web view to my app: NSURL *url = [NSURL URLWithString:@"http://www.google.co.uk?q=hello"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 400)]; webView.delegate=self; [webView loadRequest:request]; [self.view addSubview:webView]; Using the following transformation: [webView setTransform:CGAffineTransformMakeScale(0.6, 0.6)]; ..the scale is really bad quality and there appears to be no anti-aliasing. Does anyone know why this is happening or have a suggestion on how it could be fixed? Thanks! Nick.

    Hello, I have a test suite to perform smoke tests. I have all my script stored in various classes but when I try and run the test suite I can't seem to get it working if it is in a class. The code is below: (a class to call the tests) from alltests import SmokeTests class CallTests(SmokeTests): def integration(self): self.suite() if __name__ == '__main__': run = CallTests() run.integration() And the test suite: class SmokeTests(): def suite(self): #Function stores all the modules to be tested modules_to_test = ('external_sanity', 'internal_sanity') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests unittest.main(defaultTest='suite') This output's an error: Attribute Error: 'module' object has no attribute 'suite' So I can see how to call a normal function defined but I'm finding it difficult calling in the suite.

  • Joda time : How to convert String to LocalDate?

    - by bsreekanth
    Hello, How to specify the format string to convert the date alone from string. In my case, only the date part is relevant Constructing it as DateTime fails: String dateString = "2009-04-17"; DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd"); DateTime dateTime = formatter.parseDateTime(dateString); with error java.lang.IllegalArgumentException: Invalid format: "2011-04-17" is too short Probably because I should use LocalDate instead. But, I do not see any formatter for LocalDate . What is the best way to convert String dateString = "2009-04-17"; into LocalDate (or something else if that is not the right representation) thanks...
