  • Strange behaviour using Drag and Drop in word 2003 automation in headers

    - by Oliver Hanappi
    Hi! I am developing a template based addin for Word 2003 which allows the user to drag and drop elements from a listbox into the word document. Unfortunately I'm getting a really strange behaviour when trying to drop elements in the document's header. Open the template and type something in the header Close the header and insert some content on the page Add a page break. Switch to page layout mode where and set zoom level to "Two Pages" Open the header Slowly Drag and Drop an list item from the list box to the header. See multiple Page Setups dialogs occur which cause Word to crash. Here is my code: // in ThisDocument.cs public MyUserControl _control; public void Init() { _control = new MyUserControl(); ActionsPane.Controls.Add(_control); ActionsPane.Visible = true; } // in MyUserControl.cs public void listBox1_MouseDown(object sender, MouseEventArgs e) { DoDragDrop("something", DragDropEffects.Copy); } Have I done somethinkg wrong with implementing Drag and Drop? Is there a workaround for this strange behaviour? Thanks in advance, Oliver Hanappi

  • NSTableView Drag and Drop not working

    - by macatomy
    Hi, I'm trying to set up very basic drag and drop for my NSTableView. The table view has a single column (with a custom cell). The column is bound to an NSArrayController, and the array controller's content array is bound to an NSArray on my controller object. The data displays fine in the table. I connected the dataSource and delegate outlets of the table view to my controller object, and then implemented these methods: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { NSLog(@"dragging"); return YES; } - (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(NSInteger)row proposedDropOperation:(NSTableViewDropOperation)op { return NSDragOperationEvery; } - (BOOL)tableView:(NSTableView *)aTableView acceptDrop:(id <NSDraggingInfo>)info row:(NSInteger)row dropOperation:(NSTableViewDropOperation)operation { return YES; } I also registered the drag types in -awakeFromNib: #define MyDragType @"MyDragType" - (void)awakeFromNib { [super awakeFromNib]; [_myTable registerForDraggedTypes:[NSArray arrayWithObjects:MyDragType, nil]]; } The problem is that the -tableView:writeRowsWithIndexes:toPasteboard: method is never called. I've looked at a bunch of examples and I can't figure out anything I'm doing wrong. Could the problem be that I'm using a custom cell? Is there something I'm supposed to override in the cell subclass to enable this functionality? EDIT: Confirmed. Switching the custom cell for a regular NSTextFieldCell made dragging work. Now, how do I make drag and drop work with my custom cell?

  • SWT Drag and Drop support for Text widget

    - by bryantsai
    I've written an application recently using SWT. In one of its dialog box, I have a few widgets, one of which is Text, which is designed to support DND with other widgets. I've first added DND support for the 2 Tree widgets on the same dialog box (both drag source and drop target). Before I added DND support for that Text widget, I noticed that on Linux platform (gtk), SWT Text widget automatically get drag and drop support. That is, I can already drag from the other Tree widgets and drop on this Text (at any position to inserted there), as well as selecting and dragging any text from this Text to other Tree or Text widget. However, this is only working on Linux platform but not on Windows. The same program, if running on Windows, will not have any DND support for that Text widget (Tree widgets of course have DND support since I specifically write for them). So here's what I want to achieve on Windows as well: drop text at any position in Text widget. before dropping and while hovering, able to see the caret position clearly where the intended position to drop. caret position should move along with the mouse cursor. support multi-line in Text widget SOLUTION: DropTarget target = new DropTarget(sytledText, DND.DROP_MOVE | DND.DROP_COPY); target.setTransfer(new Transfer[] { TextTransfer.getInstance() }); target.addDropListener(new StyleTextDropTargetEffect(sytledText)); Use StyledText instead of Text widget Use StyledTextDropTargetEffect (or extend it) and add it as dr op listener

  • detection of 'flush tables with read lock' in php

    - by theduke0
    I would like to know from my application if a myisam table can accept writes (i.e. not locked). If an exception is thrown, everything is fine as I can catch this and log the failed statement to a file. However, if a 'flush tables with read lock' command has been issued (possibly for backup), the query I send will pretty much hang out forever. If one table is locked at a time, insert delayed works well. But when this global lock is applied, my query just waits. The query I run is an insert statement. If this statement fails or hangs, user experience is degraded. I need a way to send the query to the server and forget about it (pretty much). Does anyone have any suggestions on how to deal with this? -set a query timeout? -run asyncronous request and allow for the lock to expire while application continues? -fork my php process? Please let me know if I can provide and clarification or details.

  • Memory Barrier by lock statement

    - by jalalaldeen
    I read recently about memory barrier and the reordaring issue and now I have some confusion about it. Let us have a following senario: private object _object1 = null; private object _object2 = null; private bool _usingObject1 = false; private object MyObject { get { if (_usingObject1) { return _object1; } else { return _object2; } } set { if (_usingObject1) { _object1 = value; } else { _object2 = value; } } } private void Update() { _usingMethod1 = true; SomeProperty = FooMethod(); //.. _usingMethod1 = false; } 1- At Update method; is it always _usingMethod1 = true statement excecuted before getting or setting the property? or due reordaring issue we can not garantee that? 2- Should we use volitle like. private volitle bool _usingMethod1 = false; 3- If we use lock; can we garantee then every statement within the lock will be excecuted in order like: private void FooMethod() { object locker = new object(); lock (locker) { x = 1; y = a; i++; } } Thanks in advanced..

  • USB Hardware vs. Software Write Lock

    - by TreyK
    I'm in the market for a USB flash drive, and remember this cool feature a tiny 32MB flash drive of mine had: a write lock switch. This seemed like it would be an amazing feature to have as a shield against any nastiness happening to the drive on an unfamiliar computer. However, very few drives on the market offer this feature. Instead, it seems that forms of software protection are the more prominent method. This software protection causes me a bit of uneasiness, as it seems like this software wouldn't be nearly as bulletproof as a physical switch. Also, levels of protection seem to vary from product to product. Being able to protect certain folders from reading and/or writing would be nice, but is the security trade-off worth it? Just how effective can this software protection be? Wouldn't a simple format be able to clean any drive with software protection? My drive must also be compatible with Windows XP, Vista, and 7, as well as Linux and Mac. What would be the best way forward for getting a well-sized (~8GB) flash drive with a strong write protection implementation, for little or no more than a regular drive? Thanks.

  • 'txn-current-lock': Permission denied [500, #13] - Subversion + Apache Configuration Issue

    - by wfoster
    Current Setup Fedora 13 32bit Apache 2.2.16 Subversion repositories setup under /var/www/svn I have two different repositories under this directory so my /etc/httpd/conf.d/subversion.conf setup in this way; LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so <Location /svn> DAV svn SVNListParentPath on SVNParentPath /var/www/svn <LimitExcept GET PROPFIND OPTIONS REPORT> AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/httpd/.htpasswd Require valid-user </LimitExcept> </Location> After copying over my repos and using; chmod 755 -R /var/www/svn chcon -R -t httpd_sys_content_t /var/www/svn chown apache:apache -R /var/www/svn I can browse my repos fine through the browser, and I can update all my working copies, however when I try to check in from anywhere I get the same error Can't open file '/var/www/svn/repo/db/txn-current-lock':Permission denied I have been working on this issue for a while now and cant seem to find a solution to my issues. It might be of some use to know that the repo existed on a different server before this, it has been now moved to this new server. Everything I have read seems to indicate that the permissions for apache are incorrect, however apache is set to run as User apache and Group apache. So as far as I can tell my setup is correct. The behavior is not though. Any Ideas? Solution The only way I was able to get this to work is to disable SELinux, it could also be done by setting the proper booleans with SELinux via setsetbool and getsebool since this is just a home server, I decided to disable SELinux and am reaping the benefits now.

  • Protocol to mount fat32 network filesystem on Linux with ability to lock files ( not advisory locks

    - by nagul
    I have a fat32 filesystem sitting on a NAS storage device (nslu2) that I need to mount on my Ubuntu system. I've tried Samba and NFS mounts, but both don't seem to support proper locking. More specifically, I am unable to save files to the mounted drive through GNUcash, KeepassX etc, which makes the share fairly useless. Is there a protocol that allows me to achieve this ? Note that the NAS storage device is running a linux OS so I can run pretty much any protocol that has a linux implementation. The only option I'm not looking for is to reformat the partition to ext3, which I'm not able to do due to other constraints. Alternatively, has anyone managed proper locking of a fat32 system over the network using Samba ? Or, is advisory locking the best you get with a network-mounted fat32 file system ? I've thought of trying sshfs but I've not found any indication that this will solve my problem. Edit: Okay, maybe I can reformat the drive, but to any file system except ext3. The "unslung" nslu2 doesn't like more than one ext3 drive, and I already have one attached. So any solution that involves reformatting the drive to ntfs, hfs etc is fine, as long as I can mount it on linux and lock files.

  • Timeout settings for Remote Desktop Sessions to lock

    - by atroon
    Our office uses a Windows 2003 server to provide access to an accounting application. Recently I was asked to increase the amount of time it takes for the session to lock itself and require the entry of the user's password to resume. That seems to be about ten minutes, at present. I am familiar with group policy and have tweaked those settings to scavenge sessions (and thereby licenses) from sessions that have been disconnected (by the user closing the mstsc.exe client or by a network issue). That's simple and straightforward. But I can't find anything in GP to allow a longer time period before the RDP client window goes black and then, when clicked upon, requires a username and password to resume the session. I must admit this would be nice personally as well, since most of my time is spent documenting the application and/or monitoring its database, so I usually have a window open to the terminal server along with the rest of the staff in the accounting center, but I interact with it very little. I usually enter my password 10-15 times per workday, but I'm pretty good at it by now. ;) So, can this timeout period be adjusted, or are we out of luck?

  • Explorer forgetting how to cut and paste files

    - by raimesh
    My Windows XP (SP3) machine (at work) occasionally "forgets" how to cut-and-paste files in Explorer - if I cut or copy a file then go to paste it elsewhere, the "paste" and "paste shortcut" menu items are greyed out. The keyboard shortcuts (Ctrl+X/Ctrl+C,Ctrl+V) don't work either, and neither does Drag-and-Drop - clicking and dragging a file/folder doesn't change the pointer and letting go doesn't drop the item anywhere. Restarting the explorer.exe process usually fixes the problem, but sometimes I need to do a full reboot. Note: this may be related to the following existing question, although that's Vista and it sounds like the asker has more permanent problems than I do: http://superuser.com/questions/27045/copy-paste-in-vista-explorer-broken-not-ms-vpc So, any idea what might be causing the problem and how to avoid it?

  • WPF DataGrid does not scoll on drag

    - by Greg R
    I have a strange problem with a WPF DataGrid from WPF Toolkit. The scrollbars appear correctly when the number of rows grows, and the scrolling works when you press up or down arrows on the scrollbar. The problem comes in when I try to drag the scrollbar on the datagrid. My page has a scroll viewer around it. When I click and drag the scrollbar on the grid, it scrolls the page scroller instead. If the scrollbar does not apear on the page, there grid still does not scroll. Is there a workaround for this??? Would really appreciate some help with this issue! For example, in this case if the page is < 280, it scrolls on drag. But drag scrolling does not work on the grid. <ScrollViewer ScrollViewer.IsDeferredScrollingEnabled="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" > <DockPanel> <dg:DataGrid HorizontalScrollBarVisibility="Auto" SelectionMode="Single" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeColumns="False" CanUserSortColumns="False" AutoGenerateColumns="False" RowHeaderWidth="17" ItemsSource="{Binding Path=OrderSearchVm}" IsReadOnly="True" MaxHeight="280" DockPanel.Dock="Top"> <dg:DataGrid.Columns> <dg:DataGridTextColumn Width="75" Header="Date" Binding="{Binding Path=OrderDate}" > <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Type" Binding="{Binding Path=OrderType}" Width="45"/> <dg:DataGridTextColumn Header="Shipping Name" Binding="{Binding Path=ShipToName}" Width="115"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Shipping Address " Binding="{Binding Path=ShipToAddress}" Width="160"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="E-Mail" Binding="{Binding Path=Email}" Width="140"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> </dg:DataGrid.Columns> </dg:DataGrid> </DockPanel> </ScrollViewer>

  • JDBC Lock a row using SELECT FOR UPDATE, doesn't work

    - by Rachid
    I am having issues with MySQL's SELECT .. FOR UPDATE, here is the query I am trying to run: SELECT * FROM tableName WHERE HostName='UnknownHost' ORDER BY UpdateTimestamp asc limit 1 FOR UPDATE After this, the concerned thread will do an UPDATE and change the HostName, which is then it should unlock the row. I am running a multi-threaded java application, so 3 threads are running this SQL statement, but when thread 1 runs this, it doesn't lock its results from thread 2 & 3. Therefore threads 2 & 3 are getting the same results and they could update the same row. Also each thread is on its own mysql connection. I'm using Innodb, with transaction-isolation = READ-COMMITTED, and the Autocommit is off before executing the select for update may I miss something? OR perhaps there is a better solution? Thanks a lot. Code : public BasicJDBCDemo() { Le_Thread newThread1=new Le_Thread(); Le_Thread newThread2=new Le_Thread(); newThread1.start(); newThread2.start(); } Thread : class Le_Thread extends Thread { public void run() { tring name = Thread.currentThread().getName(); System.out.println( name+": Debut."); long oid=Util.doSelectLockTest(name); Util.doUpdateTest(oid,name); } } Select : public static long doSelectLockTest(String threadName) { System.out.println("[OUTPUT FROM SELECT Lock ]...threadName="+threadName); PreparedStatement pst = null; ResultSet rs=null; Connection conn=null; long oid=0; try { String query = "SELECT * FROM table WHERE Host=?

  • How to Treat Race Condition of Session in Web Application?

    - by Morgan Cheng
    I was in a ASP.NET application has heavy traffic of AJAX requests. Once a user login our web application, a session is created to store information of this user's state. Currently, our solution to keep session data consistent is quite simple and brutal: each request needs to acquire a exclusive lock before being processed. This works fine for tradition web application. But, when the web application turns to support AJAX, it turns to not efficient. It is quite possible that multiple AJAX requests are sent to server at the same time without reloading the web page. If all AJAX requests are serialized by the exclusive lock, the response is not so quick. Anyway, many AJAX requests that doesn't access same session variables are blocked as well. If we don't have a exclusive lock for each requests, then we need to treat all race condition carefully to avoid dead lock. I'm afraid that would make the code complex and buggy. So, is there any best practice to keep session data consistent and keep code simple and clean?

  • Silverlight Toolkit ListBoxDragTarget Only One Way

    - by Tom Allen
    I've got a Silverlight 3 app that has two ListBoxes that I need to be able to drag items between. I've got the toolkit control working so that I can drag from ListBox lbA to ListBox lbB but i then can't drag the item from lbB back to lbA. <toolkit:ListBoxDragDropTarget mswindows:DragDrop.AllowDrop="True"> <ListBox x:Name="lbA" Style="{StaticResource ListBoxStyle}"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayMember}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </toolkit:ListBoxDragDropTarget> <toolkit:ListBoxDragDropTarget mswindows:DragDrop.AllowDrop="True"> <ListBox x:Name="lbB" Style="{StaticResource ListBoxStyle}" Width="350"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayMember}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </toolkit:ListBoxDragDropTarget> I'm binding lbA to an ObservableCollection of MyObject items which is a parent class for objects MyObjectA and MyObjectB (and there is a mix of ChildObjectA and ChildObjectB items). Is the one way behaviour I'm seeing due to binding to a collection MyObjects or something else i'm missing?

  • NHibernate mapping with optimistic-lock="version" and dynamic-update="true" is generating invalid up

    - by SteveBering
    I have an entity "Group" with an assigned ID which is added to an aggregate in order to persist it. This causes an issue because NHibernate can't tell if it is new or existing. To remedy this issue, I changed the mapping to make the Group entity use optimistic locking on a sql timestamp version column. This caused a new issue. Group has a bag of sub objects. So when NHibernate flushes a new group to the database, it first creates the Group record in the Groups table, then inserts each of the sub objects, then does an update of the Group records to update the timestamp value. However, the sql that is generated to complete the update is invalid when the mapping is both dynamic-update="true" and optimistic-lock="version". Here is the mapping: <class xmlns="urn:nhibernate-mapping-2.2" dynamic-update="true" mutable="true" optimistic-lock="version" name="Group" table="Groups"> <id name="GroupNumber" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupNumber" length="5" /> <generator class="assigned" /> </id> <version generated="always" name="Timestamp" type="BinaryBlob" unsaved-value="null"> <column name="TS" not-null="false" sql-type="timestamp" /> </version> <property name="UID" update="false" type="System.Guid, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="GroupUID" unique="true" /> </property> <property name="Description" type="AnsiString"> <column name="GroupDescription" length="25" not-null="true" /> </property> <bag access="field.camelcase-underscore" cascade="all" inverse="true" lazy="true" name="Assignments" mutable="true" order-by="GroupAssignAssignment"> <key foreign-key="fk_Group_Assignments"> <column name="GroupNumber" /> </key> <one-to-many class="Assignment" /> </bag> <many-to-one class="Aggregate" name="Aggregate"> <column name="GroupParentID" not-null="true" /> </many-to-one> </class> </hibernate-mapping> When the mapping includes both the dynamic update and the optimistic lock, the sql generated is: UPDATE groups SET WHERE GroupNumber = 11111 AND TS=0x00000007877 This is obviously invalid as there are no SET statements. If I remove the dynamic update part, everything gets updated during this update statement instead. This makes the statement valid, but rather unnecessary. Has anyone seen this issue before? Am I missing something? Thanks, Steve

  • How To AutoScroll a DataGridView during Drag and Drop

    - by Mason
    One of the forms in my C# .NET application has multiple DataGridViews that implement drag and drop to move the rows around. The drag and drop mostly works right, but I've been having a hard time getting the DataGridViews to AutoScroll - when a row is dragged near the top or bottom of the box, to scroll it in that direction. So far, I've tried implementing a version of this solution. I have a ScrollingGridView class inheriting from DataGridView that implements the described timer, and according to the debugger, the timer is firing appropriately, but the timer code: SendMessage(Handle, WM_VSCROLL, (IntPtr)scrollDirectionInt, IntPtr.Zero); doesn't do anything as far as I can tell, possibly because I have multiple DataGridViews in the form. I also tried modifying the AutoScrollOffset property, but that didn't do anything either. Investigation of the DataGridView and ScrollBar classes doesn't seem to suggest any other commands or functions that will actually make the DataGridView scroll. Can anyone help me with a function that will actually scroll the DataGridView, or some other way to solve the problem?

  • safely lock a file then move? windows

    I have a file and need to ensure it exist before inserting a row into the db. After i insert i need to use the PK as part of the filename and move it into another location. How do i check if it exist then lock it so it cant be deleted until i can insert into the db then proceed to move the file without it being deleted upon releasing the lock? also the file may be in use. I am thinking of copying the file into a safe location then moving that file away. In this case i need to copy a file that is being used for reading. How can i do the above steps safely? Using .NET

  • Release another user's lock obtained with sp_getapplock on SQL Server

    - by joshperry
    We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

  • Custom calendar drag drop event: Find date dropped to

    - by cpf
    Hi stackoverflow, I've been working in silverlight to do a date-oriented application. I started off with changing the calendar template to contain a listbox on every date, and I created a listbox containing simple items. I implemented an easy drag drop on both those elements, so now I can drag from the listbox containing the items to the listbox on a date and have an event. Downside is: In the event, I don't know which date it was dropped to. How can I figure this out? Please note: The date dropped to is not necessarily the date currently selected...
