    - by Deveti Putnik
    Here is the code in C++ dll: extern "C" _declspec(dllexport) int testDelegate(int (*addFunction)(int, int), int a, int b) { int res = addFunction(a, b); return res; } and here is the code in C#: public delegate int AddIntegersDelegate(int number1, int number2); public static int AddIntegers(int a, int b) { return a + b; } [DllImport("tester.dll", SetLastError = true)] public static extern int testDelegate(AddIntegersDelegate callBackProc, int a, int b); public static void Main(string[] args) { int result = testDelegate(AddIntegers, 4, 5); Console.WriteLine("Code returned:" + result.ToString()); } When I start this small app, I get the message from the header of this post. Can someone help, please? Thanks in advance, D

  • Add characters (',') every time a certain character ( , )is encountered ? Python 2.7.3

    - by draconisthe0ry
    Let's say you had a string test = 'wow, hello, how, are, you, doing' and you wanted full_list = ['wow','hello','how','are','you','doing'] i know you would start out with an empty list: empty_list = [] and would create a for loop to append the items into a list i'm just confused on how to go about this, I was trying something along the lines of: for i in test: if i == ',': then I get stuck . . .

  • FTP - way to programatically determine time remaining or bytes transfered?

    - by ciaranarcher
    Hi all I want to make an FTP connection (ideally using Coldfusion 8, but Java is fine too) that will copy a file to a remote server. Crucially however, I want to know how many bytes have been transferred so I can give some feedback to the user. Is this possible, and if so what FTP API would you recommend as I understand the Sun implementation may be a bit lacking. Thanks in advance! PS: I could have another process/thread poll the file size on the destination machine via a web service call while the file is being transferred but it's not ideal. Getting it through FTP API would be the neatest solution.

  • Can I save my app's state at close time in iPhone OS?

    - by Steve
    I have an app that functions much like an ebook. I have a bunch of textual information in various languages that is accessible through a number of drill down methods. When a user wants to get into where they were reading last, they currently have to navigate through the section and chapter menus to get back to where they were. An ideal solution for this would be to setup a bookmark system, which I am considering. But if I remember correctly, when iPhone OS 4 was announced, they seemed to make a big deal of the added ability to save the state of an app. Does that mean that someone using my reader app would be able to just exit right out, do whatever, and then when they came back in, it would be the reading screen just as they left it? I don't know much about how to setup a bookmarking system, I suppose it would be worth investigating, but I would probably want to just hold off for iPhone OS 4 if that is indeed what it will be capable of doing. Any thoughts or insights would be appreciated!!

  • What will happen if the code can't finished on time...

    - by Tattat
    If I set a timer to execute a code every 3 seconds. If the code isn't finished in 3 seconds, what will happen? The computer will terminal the code or wait for the code finish or continue the timer, and execute the code with the unfinished code concurrently. int delay = 0; // delay for 0 sec. int period = 3000; // repeat 3 sec. Timer timer = new Timer(); timer.scheduleAtFixedRate(new TimerTask() { public void run() { // Task here ... // It may take more than 3 sec to finish, what will happen? } }, delay, period);

  • How to do a Translate Animation for both axis(X, Y) at the same time?

    - by user1235555
    I am doing something like this in my Storyboard method but not able to achieve the desired result. This animation I want to be played after the page is loaded. private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e) { CreateTranslateAnimation(image1); } private void CreateTranslateAnimation(UIElement source) { Storyboard sb = new Storyboard(); DoubleAnimationUsingKeyFrames animationFirstX = new DoubleAnimationUsingKeyFrames(); source.RenderTransform = new CompositeTransform(); Storyboard.SetTargetProperty(animationFirstX, new PropertyPath(CompositeTransform.TranslateXProperty)); Storyboard.SetTarget(animationFirstX, source.RenderTransform); animationFirstX.KeyFrames.Add(new EasingDoubleKeyFrame() { KeyTime = kt1, Value = 20 }); DoubleAnimationUsingKeyFrames animationFirstY = new DoubleAnimationUsingKeyFrames(); source.RenderTransform = new CompositeTransform(); Storyboard.SetTargetProperty(animationFirstY, new PropertyPath(CompositeTransform.TranslateYProperty)); Storyboard.SetTarget(animationFirstY, source.RenderTransform); animationFirstY.KeyFrames.Add(new EasingDoubleKeyFrame() { KeyTime = kt1, Value = 30 }); sb.Children.Add(animationFirstX); sb.Children.Add(animationFirstY); sb.Begin(); } Too cut it short... I want to write .cs code equivalent to this code <Storyboard x:Name="Storyboard1"> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="image1"> <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="20"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="image1"> <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="30"/> </DoubleAnimationUsingKeyFrames> </Storyboard>

  • WCF or Sockets for Communication in a real-time environment?

    - by PieterG
    I have a scenario where I need to send a series of data across 2 clients. The data includes Serialized XML that will contain commands that the other client will need to react to. I will also need to send images across the wire as I need to provide a chat facility in the form of video/audio chat. I would like a single communication medium for both, as the number of messages/commands might be a few. WCF or Sockets?

  • Is there a tool that will show diagrams of my SQL database in real-time?

    - by Rising Star
    I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at a demo that the new version of Visual Studio 2010 has a new feature called the "Architect Explorer", which allows developers to view relationships among .net classes on the fly. It has many features for filtering the data that the developer is interested in. It would be really awesome if I could visually browse my tables and stored procedures and see what is related to what by primary key, foreign key, and referenced in stored procedures. I realize that I'm talking about two entirely different technologies and it's not a perfect analogy, but is there some similar tool that would allow me to visualize tables in my SQL database?

  • Cursor loops; How to perform something at start/end of loop 1 time only?

    - by James.Elsey
    I've got the following in one of my Oracle procedures, I'm using it to generate XML -- v_client_addons is set to '' to avoid null error OPEN C_CLIENT_ADDONS; LOOP FETCH C_CLIENT_ADDONS INTO CLIENT_ADDONS; EXIT WHEN C_CLIENT_ADDONS%NOTFOUND; BEGIN v_client_addons := v_client_addons || CLIENT_ADDONS.XML_DATA; END; END LOOP; CLOSE C_CLIENT_ADDONS; -- Do something later with v_client_addons The loop should go through my cursor and pick out all of the XML values to display, such as : <add-on name="some addon"/> <add-on name="another addon"/> What I would like to achieve is to have an XML start/end tag inside this loop, so I would have the following output <addons> <add-on name="some addon"/> <add-on name="another addon"/> </addons> How can I do this without having the <addons> tag after every line? If there are no addons in the cursor (cursor is empty), then I would like to skip this part enitrely

  • How do I execute an action in drupal after each time a node is saved?

    - by ford
    I'm developing an Action in Drupal which is supposed to activate after saving a node, exporting content to XML (which includes data from the node that was just saved), using the "Trigger: After saving an updated post" trigger. Unfortunately this action actually happens right before the information from the recently saved post is saved to the database. ie. when looking at the XML later, I find that the most recent change I made was not included. Saving after editing a different node will restore the previously missing data. How can I get my action to fire after the saving process is complete?

  • How to find out style of NSUserNotification during run-time? Or force close an alert?

    - by Dmitri Shuralyov
    According to "OS X Mountain Lion Release Notes" (https://developer.apple.com/library/mac/#releasenotes/Cocoa/Foundation.html), "The user has ultimate control over what notifications are displayed, and the style (banner, alert, etc). There is no mechanism to override the user preferences." Even though all I want to do is "downgrade" from alert style to banner style... Fine. But can I at least find out whether a notification is of alert or banner style inside the didActivateNotification method? The reason I want to do that is to respond differently according to notification.activationType. When the alert is a banner (which is what I want), clicking its contents is the only possible action, and this both triggers didActivateNotification method and closes the notification banner. When the user chooses alert-style notifications, clicking the alert contents also generates didActivateNotification with the same value of notification.activationType, but it stays on screen instead of going away (it only goes away when the Action button is pressed). I don't want my app to trigger an action repeatedly for the same alert notification, in case the user clicks the content area of an alert notification. An alternative solution would be to force the alert notification bubble to dismiss when the user clicks its contents. Is this possible?

  • How i pass my view to nib at run time(Dynamically) in viewController class?

    - by Rajendra Bhole
    Hi, I want to create viewController class programmatically in which the view of nib file of viewController is not fixed. I have a UntitledViewController class that contains 4 UIButtons: -(IBAction)buttonPressed:(id)sender{ if((UIButton *)sender == button1){ tagNumber = button1.tag; NewViewController *newVC = [[NewViewController alloc] init]; //newVC.tagN [self.navigationController pushViewController:newVC animated:YES]; NSLog(@"Button Tag Number:- %i", tagNumber); } if((UIButton *) sender == button2){ tagNumber = button2.tag; NewViewController *newVC = [[NewViewController alloc] init]; [self.navigationController pushViewController:newVC animated:YES]; } if((UIButton *) sender == button3){ tagNumber = button3.tag; NewViewController *newVC = [[NewViewController alloc] init]; [self.navigationController pushViewController:newVC animated:YES]; } if((UIButton *) sender == button4){ int x = tagNumber; tagNumber = button4.tag; NewViewController *newVC = [[NewViewController alloc] init]; newVC.untitledVC = self; [self.navigationController pushViewController:newVC animated:YES]; } } When I will click any one of the UIButtons, I want to create a new NewViewController class with button tag property but without fixed nib file. In NewViewController's loadView event I want to fix the view of the nib of NewViewController class using UIButton's tag property (In NewViewController.xib I'm creating 4 UIViews named view1, view2, view3 and view4). -(void)loadView{ [super loadView]; CGRect frame = CGRectMake(0, 0, 320, 480); UIView *newView = [[UIView alloc] initWithFrame:frame]; newView.tag = untitledVC.tagNumber; self.view1 = newView; } Now I want that when I click button1 the NewViewController will be generated with view1 and when I click button2 the NewViewController will be generated with view2 and so on with different implementation. Thanks.

  • Can I Select and Update at the same time?

    - by Ed Manet
    This is an over-simplified explanation of what I'm working on. I have a table with status column. Multiple instances of the application will pull the contents of the first row with a status of NEW, update the status to WORKING and then go to work on the contents. It's easy enough to do this with two database calls; first the SELECT then the UPDATE. But I want to do it all in one call so that another instance of the application doesn't pull the same row. Sort of like a SELECT_AND_UPDATE thing. Is a stored procedure the best way to go?

    I've got thousands of urls from many hosts I need to screenshot. I can use the lib fine from the command line, but how can I integrate it into my code so I can take multiple screenshots simultaneously?
