Legacy application creates dialogs in non-ui thread.

- by Frater

I've been working support for a while on a legacy application and I've noticed a bit of a problem. The system is an incredibly complex client/server with standard and custom frameworks. One of the custom frameworks built into the application involves validating workflow actions. It finds potential errors, separates them into warnings and errors, and passes the results back to the client. The main difference between warnings and errors is that warnings ask the user if they wish to ignore the error. The issue I have is that the dialog for this prompt is created on a non-ui thread, and thus we get cross-threading issues when the dialog is shown. I have attempted to invoke the showing of the dialog, however this fails because the window handle has not been created. (InvokeRequired returns false, which I assume in this case means it cannot find a decent handle in its parent tree, rather than that it doesn't require it.) Does anyone have any suggestions for how I can create this dialog and get the UI thread to set it up and call it?

Convert asp.net application to windows forms app

- by rogdawg

I have written and deployed an ASP.NET application that is pretty complex. It uses XSL transformations to create web forms for a large variety of data objects. The data comes from the database as XML via a web service. Now, I need to create a Windows desktop application that will provide a small subset of the web applications functionality to a user who may not have access to the web (working in remote areas). I will provide the data syncing using the MS Sync Framework. And I will have the desktop use a local data store. I would like to use the same xslt files in the desktop app that I use in the web app for the form creation so that, if changes are made, the desktop app can update itself when it connects and syncs its data. But, I am wondering how to replicate the asp.net codebehind logic of my web app in the windows forms. If I use a browser control to render the XSLTransformation result, then how could I handle click events, etc, in the form? Also, can I launch other windows as "dialog boxes" from my windows forms (I do this in my web app using RadControls functionality)? Thanks for any advice you can give.

Help: List contents of iPhone application bundle subpath??

- by bluepill

Hi, I am trying to get a listing of the directories contained within a subpath of my application bundle. I've done some searching and this is what I have come up with - (void) contents { NSArray *contents = [[NSBundle mainBundle] pathsForResourcesOfType:nil inDirectory:@"DataDir"]; if (contents = nil) { NSLog(@"Failed: path doesn't exist or error!"); } else { NSString *bundlePathName = [[NSBundle mainBundle] bundlePath]; NSString *dataPathName = [bundlePathName stringByAppendingPathComponent: @"DataDir"]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSMutableArray *directories = [[NSMutableArray alloc] init]; for (NSString *entityName in contents) { NSString *fullEntityName = [dataPathName stringByAppendingPathComponent:entityName]; NSLog(@"entity = %@", fullEntityName); BOOL isDir = NO; [fileManager fileExistsAtPath:fullEntityName isDirectory:(&isDir)]; if (isDir) { [directories addObject:fullEntityName]; NSLog(@" is a directory"); } else { NSLog(@" is not a directory"); } } NSLog(@"Directories = %@", directories); [directories release]; } } As you can see I am trying to get a listing of directories in the app bundle's DataDir subpath. The problem is that I get no strings in my contents NSArray. note: - I am using the simulator - When I manually look in the .app file I can see DataDir and the contents therein - The contents of DataDir are png files and directories that contain png files - The application logic needs to discover the contents of DataDir at runtime - I have also tried using NSArray *contents = [fileManager contentsOfDirectoryAtPath:DataDirPathName error:nil]; and I still get no entries in my contents array Any suggestions/alternative approaches? Thanks.

how to solve a weired swig python c++ interfacing type error

- by user2981648

I want to use swig to switch a simple cpp function to python and use "scipy.integrate.quadrature" function to calculate the integration. But python 2.7 reports a type error.

Intercept creation of activities when the application is restored

- by Johan Bilien

Most of our activities access a user-specific model. All these activities inherit from a ModelActivity base class, which provides a getModel() call. When one of these activities detect that the user has signed out (through the AccountManager callback), it sticks to its existing model, but prepares to exit back to the root activity (which is not user-specific) by starting its intent with FLAG_ACTIVITY_CLEAR_TOP. If however the user deletes an account while the app is not running, we run into trouble when the activity is restored. Now the activity needs to handle there not being a model, which makes the code more complicated and bug-prone. Ideally we would intercept the application restore process before the activity is created. Then we would check whether we have an account and a model, and if not clear up the saved stack of activities, and restart from our root activity instead of the last saved activity. But as far as I can tell the first place where we can run code is in the onCreate callback of the activity. Is there a way to run some code when the application is restored from background-saving, but before the saved activity is created?

PHP | SQL syntax error when inserting array

- by Philip

Hi guys, I am having some trouble inserting an array into the sql database. my error is as follows: Unable to add : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '06:45:23,i want to leave a comment)' at line 1 My query var_dump is: string(136) "INSERT INTO news_comments (news_id,comment_by,comment_date,comment) VALUES (17263,Philip,2010-05-11 06:45:23,i want to leave a comment)" My question is how can i add an empty value to id as it is the primary key and not news_id my insert function looks like this: function insertQuery($tbl, &$data) { global $mysqli; $_SESSION['errors'] = array(); require_once '../config/mysqli.php'; $query = "INSERT INTO $tbl (".implode(',',array_keys($data)).")

Im not really sure why a am getting this error. But here is my code it is meant to test palindromes disregarding punctuation. So here is my code import java.util.Scanner; public class PalindromeTester { public static void main(String [] args) { Scanner kb = new Scanner(System.in); String txt = ""; int left; int right; int cntr = 0; do { System.out.println("Enter a word, phrase, or sentence (blank line to stop):"); txt = kb.nextLine(); txt = txt.toLowerCase(); char yP; String noP = ""; for (int i = 0; i < txt.length(); i++) { yP = txt.charAt(i); if (Character.isLetterOrDigit(txt.charAt(yP))) { noP += yP; } } txt = noP; left = 0; right = txt.length() -1; while (txt.charAt(left) == txt.charAt(right) && right > left) { left++; right--; } if (left > right) { System.out.println("Palindrome"); cntr++; } else { System.out.println("Not a palindrome"); } } while (!txt.equals("")); System.out.println("You found " + cntr + " palindromes. Thank you for using palindromeTester."); } } And if i test it and then i put enter so it will tell me how many palindromes you found the error i am getting is javav.lang.StringIndexOutOfBoundException : String index out of range 0 at PalindromeTester.main(PalindromeTester.java:38) and line 28 is while (txt.charAt(left) == txt.charAt(right) && right > left) Thanks for the help in advance

Error with threads during automatic testing on TeamCity 5

- by yeyeyerman

Hello, I'm having some problems executing the tests of the application I'm developing. All the tests execute normally with ReSharper and in NCover. However, the execution of one of these tests in TeamCity is generating an error. This test initializes two objects, the object under test and a simulator of a real object. Both objects will communicate throug a serial link in a representation of the real scenario. ObjectSimulator r_simulator = new ObjectSimulator(...); ObjectDriver r_driver = new ObjectDriver(...); Assert.IsTrue(r_driver.Connect() == ErrorCode.Success); The simulator just do the following in the constructor public class ObjectSimulator { ... public ObjectSimulator() { // serial port configuration m_port = new SerialPort(); m_port.DataReceived += DataReceivedEvent; } ... } The main object has two threads. The main thread of the application and a timer to refresh a watchdog timer in the real object. public ErrorCode Connect() { ... StartSynchroTimer(); Thread.Sleep(4); // to check if the timer is working properly ... } The problem is comming from the Thread.Sleep() call, as when I remove it everything works. It seems like the ObjectSimulator also sleeps and doesn't receive the DataReceived event. How can I resolve this issue?

Migrating Ajax web application to web socket

- by Bastan

Hi, I think i'm just missing a little detail that is preventing me from seeing the whole picture. I have a web application which use ajax request every x time to update client with new information or tasks. I also have a long running process on the server which is a java computation engine. I would like this engine to send update to the client. I am wondering how to migrate my web app to using websocket. Probably phpwebsocket or similar. Can my server 'decide' to send information to a specific client? It seems possible looking at the php-websocket. Can my java backend long process use the websocket server to send notification to a specific client. How? well I can say that my java app could use a class that could send over websocket instead of http. But how the websocket server knows to which client to send the 'info'. I am puzzle by all this. Any document that explain this in more details? It seems that the websocket could create an instance of my web application. Thanks

Running an application from an USB device...

- by Workshop Alex

I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

Need help/guidance about creating a desktop application with gui

- by Somebody still uses you MS-DOS

I'm planning to do an Desktop application using Python, to learn some Desktop concepts. I'm going to use GTK or Qt, I still haven't decided which one. Fact is: I would like to create an application with the possibility to be called from command line, AND using a GUI. So it would be useful for cmd fans, and GUI users as well. It would be interesting to create a web interface too in the future, so it could be run in a server somewhere using an html interface created with a template language. I'm thinking about two approaches: - Creating a "model" with a simple interface which is called from a desktop/web implementation; - Creating a "model" with an html interface, and embeb a browser component so I could reuse all the code in both desktop/web scenarios. My question is: which exactly concepts are involved in this project? What advantages/disadvantages each approach has? Are they possible? By naming "interface", I'm planning to just do some interfaces.py files with def calls. Is this a bad approach? I would like to know some book recommendations, or resources to both options - or source code from projects which share the same GUI/cmd/web goals I'm after. Thanks in advance!

Error when using jquery webservice call to populate dropdownlist

No class def found error for JUnit Test on android

- by J Bellamy

I am having some very bizarre behaviour. I have a large number of test cases for my Android application, and they all work except for one. When I run this one I get a java.lang.NoClassDefFoundError: org.JUnit.test Yes, I have the JUnit 4 library imported into the project, and my other JUnit tests are running without any problems. What is particularly bizarre is that before I hit this problem I had an error in my code- basically, I tried writing a file to a read only folder. When that occurred, the JUnitTest would execute up to the point where it would hit an IO exception for accessing a part of memory it cannot access. I fix this problem, and suddenly the Android emulator doesn't seem to know what org.JUnit.test is. I have examined the run configuration for this test class, and it is the same as my others. It is in the same folder as the other tests as well. It also uses the same import statements. Any idea on what is going on? I am using the Android 10 emulator, and eclipse version 3.7.2. Edit: To clarify, the error I get appears on Logcat and not in my Eclipse project.

I have one macro, which is called when a cell change occurs. This macro selects images, deletes them, and inserts another image depending on a cell value using the following code. I have the same code for two sheets. Private Sub Worksheet_SelectionChange(ByVal Target As Range) ActiveSheet.Shapes.SelectAll Selection.Delete 'insert image code here. End Sub In one sheet, it's working perfectly fine and deletes all images, while in the other sheet, it gives me the runtime error "Out of Memory" and highlights the following line: ActiveSheet.Shapes.SelectAll Can anyone tell me why this is happening? It works perfectly fine in one and not in the other. One other thing I want to tell you is it was working fine when I gave this Excel macro to my client; both sheets were working fine. Suddenly after 2 days, he started getting the error on one sheet on which he was working a lot. I don't know why this is happening. Can anyone tell me what's the reason for this and how I can solve it?

I try to kick it off from code from within the event receiver on the same content type, so when an item is updated, if there is a certain condition (status = ready for review) I start it. //This line does find the workflow association var assoc = properties.Web.ContentTypes["Experiment Document Set"].WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", ultureInfo.CurrentUICulture); //I had tried to use this line from something I found online, but it would return null //var assoc = properties.Web.WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", CultureInfo.CurrentUICulture); var result = properties.Web.Site.WorkflowManager.StartWorkflow(properties.ListItem, assoc, string.Empty, SPWorkflowRunOptions.Synchronous); //The line above gives me this error: System.ArgumentException: Workflow failed to start because the workflow is associated with a content type that does not exist in a list. Before re-starting the workflow, the content type must be added to the list. To check this, I was looking at the content type of the list item being updated and it is correct properties.ListItem.ContentType.Name "Experiment Document Set" So basically I have a workfow associated with the content type "Experiment Document Set". When I try to start a workflow from an event receiver in "Experiment Document Set", I get an error saying the content type "Experiment Document Set" does not exist in the list which doesn't make sense.

ASP.Net MVC and Windows 7 404 error

- by Paul Rivers

O.K. Stupid question..... I sepnt nearly a day getting an MVC site working, and then I published it. After that, the hell began. I'm using Windows 7, Visual Studio 2008 and MVC. I published it and first the Default.aspx wouldn't come up. I gave up on playing with that for a few and just did the easy thing a typed in default.aspx. I'll fix that problem later. So, I clicked on one of my navigation buttons which prior to this worked just fine in the internal development IIS, and I get a 404 error. I spent two days surfing the Microsoft support forums and every other support forum I can find. No fix. So, I tried something a little different. Just to see if I screwed up. I created a new TestMVC application. Set the output to a website on the local IIS. Compiled and after typing in the default.aspx (it was set as the startup file in the project) I then clicked on the About button on the base MVC application. And what do I get? 404. I know this is new, folks, but this is crazy. What is it about this process that would take this much effort to get it right, especially since it works on the test server.

Database (and ORM) choice for an small-medium size .NET Application

- by jim

I have a requirement to develop a .NET-based application whose data requirements are likely to exceed the 4 gig limit of SQL 2005 Express Edition. There may be other customers of the same application (in the future) with a requirement to use a specific DB platform (such as Oracle or SQL Server) due to in-house DBA expertise. Questions What RDBMS would you guys recommend? From the looks of it the major choices are PostGreSQL, MySQL or FireBird. I've only got experience of MYSQL from these. Which ORM tool (if any) would you recommend using - ideally one that can be swapped out between DB platforms with minimal effort? I like the look of the entity framework but unsure as to the degree to which platforms other than SQL Server are supported. If it helps, we'll be using the 3.5 version of the Framework. I'm open to the idea of using a tool such as NHibernate. On the other hand, if it's going to be easier, I'm happy to write my own stored procedures / DAL code - there won't be that many tables (perhaps 30-35).
