  • COMException Problem

    - by Jack Harvin
    Wondering if anyone could help with my problem. Below is the code, and after the code an explination of where the exception is thrown. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Web; using WatiN.Core; using System.Threading; using System.IO; namespace WindowsFormsApplication1 { public partial class Form1 : System.Windows.Forms.Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { Thread t = new Thread(createApplications); Settings.AutoStartDialogWatcher = false; t.SetApartmentState(System.Threading.ApartmentState.STA); t.Start(); } private void createApplications() { createApp("username", "password", "Test App", "This is just a test description", "http:/mysite.com"); } private void createApp(String username, String password, String appName, String description, String appUrl) { var currentBrowser = new IE("http://mysite.com/login/php"); currentBrowser.TextField(Find.ById("username")).TypeText(username); currentBrowser.TextField(Find.ById("password")).TypeText(password); currentBrowser.Button(Find.ById("submit")).Click(); currentBrowser.GoTo("http://mysite.com/createmusicapp.php"); currentBrowser.TextField(Find.ById("application_name")).TypeText(appName); currentBrowser.TextField(Find.ById("application_description")).TypeText(description); currentBrowser.TextField(Find.ById("application_url")).TypeText(appUrl); currentBrowser.RadioButton(Find.ById("client_application_desktop_1")).Click(); currentBrowser.RadioButton(Find.ById("client_application_is_writable_1")).Click(); WatiN.Core.Image captchaImage = currentBrowser.Div(Find.ById("recaptcha_image")).Image(Find.ByStyle("display", "block")); Form2 captcha = new Form2(captchaImage.Src); captcha.ShowDialog(); } } } The exception is thrown on this line: currentBrowser.TextField(Find.ById("username")).TypeText(username); BUT, it's thrown when it gets to this line: captcha.ShowDialog(); It logs in, and fills in the app details and Form2 loads fine, but once loaded, after around 2-3 seconds the exception happens. I am wondering if it's anything to do with the threads? But I wouldn't know how to solve it if it was. The complete exception thrown is: The object invoked has disconnected from its clients. (Exception from HRESULT: 0x80010108 (RPC_E_DISCONNECTED))

  • Weird behaviour of a deserialized class

    - by orloffm
    I've got a huge XML file that's being deserialized by XmlSerializer in an XSD-generated class structure. Everything used to work just fine, but now a weird thing started happening. Sometimes (50% of runs) a field of a certain object of a class that's deep in the class tree just changes to a certain value of the same field of a different object of the same class. It happens when entering some function, when debugger steps from opening "{" to the first line of code. I understand that it's stupid question, but maybe someone have any thoughts?

  • How Can I Populate Default Form Data with a ManyToMany Field?

    - by b14ck
    Ok, I've been crawling google and Django documentation for over 2 hours now (as well as the IRC channel on freenode), and haven't been able to figure this one out. Basically, I have a model called Room, which is displayed below: class Room(models.Model): """ A `Partyline` room. Rooms on the `Partyline`s are like mini-chatrooms. Each room has a variable amount of `Caller`s, and usually a moderator of some sort. Each `Partyline` has many rooms, and it is common for `Caller`s to join multiple rooms over the duration of their call. """ LIVE = 0 PRIVATE = 1 ONE_ON_ONE = 2 UNCENSORED = 3 BULLETIN_BOARD = 4 CHILL = 5 PHONE_BOOTH = 6 TYPE_CHOICES = ( ('LR', 'Live Room'), ('PR', 'Private Room'), ('UR', 'Uncensored Room'), ) type = models.CharField('Room Type', max_length=2, choices=TYPE_CHOICES) number = models.IntegerField('Room Number') partyline = models.ForeignKey(Partyline) owner = models.ForeignKey(User, blank=True, null=True) bans = models.ManyToManyField(Caller, blank=True, null=True) def __unicode__(self): return "%s - %s %d" % (self.partyline.name, self.type, self.number) I've also got a forms.py which has the following ModelForm to represent my Room model: from django.forms import ModelForm from partyline_portal.rooms.models import Room class RoomForm(ModelForm): class Meta: model = Room I'm creating a view which allows administrators to edit a given Room object. Here's my view (so far): def edit_room(request, id=None): """ Edit various attributes of a specific `Room`. Room owners do not have access to this page. They cannot edit the attributes of the `Room`(s) that they control. """ room = get_object_or_404(Room, id=id) if not room.is_owner(request.user): return HttpResponseForbidden('Forbidden.') if is_user_type(request.user, ['admin']): form_type = RoomForm elif is_user_type(request.user, ['lm']): form_type = LineManagerEditRoomForm elif is_user_type(request.user, ['lo']): form_type = LineOwnerEditRoomForm if request.method == 'POST': form = form_type(request.POST, instance=room) if form.is_valid(): if 'owner' in form.cleaned_data: room.owner = form.cleaned_data['owner'] room.save() else: defaults = {'type': room.type, 'number': room.number, 'partyline': room.partyline.id} if room.owner: defaults['owner'] = room.owner.id if room.bans: defaults['bans'] = room.bans.all() ### this does not work properly! form = form_type(defaults, instance=room) variables = RequestContext(request, {'form': form, 'room': room}) return render_to_response('portal/rooms/edit.html', variables) Now, this view works fine when I view the page. It shows all of the form attributes, and all of the default values are filled in (when users do a GET)... EXCEPT for the default values for the ManyToMany field 'bans'. Basically, if an admins clicks on a Room object to edit, the page they go to will show all of the Rooms default values except for the 'bans'. No matter what I do, I can't find a way to get Django to display the currently 'banned users' for the Room object. Here is the line of code that needs to be changed (from the view): defaults = {'type': room.type, 'number': room.number, 'partyline': room.partyline.id} if room.owner: defaults['owner'] = room.owner.id if room.bans: defaults['bans'] = room.bans.all() ### this does not work properly! There must be some other syntax I have to use to specify the default value for the 'bans' field. I've really been pulling my hair out on this one, and would definitely appreciate some help. Thanks!

  • Updating Commit Message in Mercurial MQ extension

    After using hg qnew and hg qrefresh to create and update a patch that I want to apply to my repository, but the commit message that I wrote when I did hg qnew was not very good, it did not reference the ticket number from trac, and I would like to say something in it about some of the issues that my commit addresses. How do I do something like hg qrewritemycommitmessage. I have examined the docs on the website (starting here: http://mercurial.selenic.com/wiki/MqExtension ) and I have come up blank.

  • How to use OUTPUT statement inside a SQL trigger?

    - by Jeff Meatball Yang
    From MSDN: If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT. Can someone give me an example of this? I'm not sure if this is correct: create trigger MyInterestingTrigger on TransactionalTable123 AFTER insert, update, delete AS declare @batchId table(batchId int) insert SomeBatch (batchDate, employeeId) output SomeBatch.INSERTED.batchId into @batchId insert HistoryTable select b.batchId, i.col1, i.col2, i.col3 from TransactionalTable123.inserted i cross join @batchId b

  • Powershell GUI: Adding multiple instances of .tooltipseperate to menu

    - by obious
    So, I'm having a problem whereby for some reason I can only add one instance of a .tooltipseperator to a drop down menu. E.g. I have to create a new .tooltipseperator if I want to add another to a different menu list. I have this: $seperator = new-object System.Windows.Forms.Toolstripseparator $seperator1 = new-object System.Windows.Forms.Toolstripseparator which correlates to this: [Void]$packages_menu_bar.DropDownItems.Add($seperator1) [Void]$packages_menu_bar.DropDownItems.Add($Remove_from_AD) [Void]$process.DropDownItems.Add($Kill_process) [Void]$process.DropDownItems.Add($seperator) My question is this: how can I add the same instance on a .tooltipseperater to different menu items? Some sort of array? Thanks

  • How to enable i18n from within setup_app in websetup.py ?

    - by daniel
    From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  • How to get equivalent of ResultSetMetaData without ResultSet

    - by javanix
    Hey Guys - I need to resolve a bunch of column names to column indexes (so as to use some of the nice ResultSetMetaData methods). However, the only way that I know how to get a ResultSetMetaData object is by calling getMetaData() on some ResultSet. The problem I have with that is that grabbing a ResultSet takes up uneccesary resources in my mind - I don't really need to query the data in the table, I just want some information about the table. Does anyone know of any way to get a RSMD object without getting a ResultSet (from a potentially huge table) first? Thanks!

    This is really just a syntax question. I have a PHP script that parses my WordPress feed and returns the latest posts. I also want my script to parse the # of comments, but the WordPress feed XML object for number of comments has a colon in it (slash:comments). It causes the following error: Parse error: syntax error, unexpected ':' in ... on line ... I have tried each of the following without luck: $xml->slash:comments $comments = 'slash:comments' $xml->$comments $xml->slash.':'.comments $xml->{slash:comments} $xml->{'slash:comments'} How do I parse an object with a colon?

  • synchronized block in JSP tag class

    - by Sudhakar
    Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())
