  • How do I detect when a cell's value has changed in Silverlight?

    - by jvenema
    Hey folks, I'm working in Silverlight, trying to figure out how to set a grid cell font color based on the contents of the cell. I have an ObservableCollection bound to a DataGrid, and my items implement INotifyPropertyChanged so the grid updates as I change the values; it's all working perfectly, including letting me sort items and keep the sorting while I update the underlying items. I know I can use the LoadingRow event to change colors, but the only way I can get the event to fire is by changing the grids datasource, in which case my sorting goes out the window. So, what I really want is a way to either 1) loop the rows in the datagrid, find the cell I need, and change it's color or 2) implement a custom column that I can use to dynamically set the color. The problem is how to actually do either of those things :) All suggestions welcome.

  • Commutative (operational transform) diffs for databases

    - by barrycarter
    What Unix program generates "diff"s between text files (or INSERT/UPDATE/DELETEs for databases) in such a way that the order that the "diff"s are applied in is irrelevant, and the result is the same regardless of order. Etherpad used to do something like this. Example (for a given document or database): % Adam makes a change X, then Bob makes a change Y, then Adam makes another change Z. % However, because of network latency, Adam sees the changes in this order: XZY, while Bob sees them in this order: YXZ. % However, the code/changes are written so that XYZ and YXZ yield the same result. Note: ideally, this can be done without having to do X/Y/Z inverse at any point. I have read http://stackoverflow.com/questions/2043165/operational-transformation-library but I'm not sure this really does what I want.

  • How can I show SQL Server LOGS (2005)

    - by Marcin Rybacki
    Hello, I'm trying to track the error thrown by SQL Server 2005. The problem is SQL Server reports it in my native language so it's hard for me to google it. I think that the core issue would be avialable in English in SQL Server LOGS. I'm running SQL Server Management Studio Express, going to "Management" node, and then SQL Server Logs. I can see the list of logs but I cannot enter them, the only available option in context menu is Refresh. Could you help me to show the contents of those logs?

    - by ismail
    Hi, I urgently need help, please. WebtextEdit ClientSideEvent execute javascript statement on mousemove event. I can successfully change the style of another object type on this WebTextEdit ClientSide MouseMove event: document.getElementById("Object2").style.backgroundColor = '#F0F5F7'; But when I want to change the style of the WebTextEdit control: document.getElementById("WebTextEdit1").style.backgroundColor = '#F0F5F7'; Then nothing happens.

  • Javascript Problem! Not changing the css style

    - by mathew
    I have this code in JavaScript: function change() { document.getElementById("mem").className = 'gif'; } The fig and gif are like this: a.fig { background: #FFFFFF; } a.gif { background: #000099 ; } and the function is used like this <a class ="fig" id ="mem" onClick="javascript:change()" href="users" > Where the only difference between gif and fig in CSS is that they have different background colors. The problem is that the change is only noticeable in just a second and it is not permanent! Any ideas?

  • Where is the xorg.conf file in Karmic Koala (Ubuntu 9.10) ?

    - by jfmessier
    I am trying to change this xorg.conf file that I used to modify under Ubuntu 9.04, so it can have the higher resolutions of my monitor. Under 9.04, the monitor was unknown, and I had to key in all resolutions in the file, and although it is found under 9.10, 9.10 does not have the highest resolution that My monitor can sustain. How can I change such setting ? Is xorg.conf moved, or replaced ? Merci :-) JF

  • Is DNS propagation still slow?

    - by spiffytech
    I've been told to assume it takes as long as 48 hours for a DNS change to propagate throughout the entire Internet, because some DNS servers cache their entries for longer than my TTL. However, for years and across ISPs and domains, every time I've made a DNS change I see the effects within a couple of hours. Is it still true that I need to assume a full two days for everyone to see my changes?

  • Add user in CentOS 5

  • Can I use TCP as DNS query protocol on Mac OS?

    - by Brian
    Hi, I'm using Mac OS, Snow Leopard 10.6.2, and I'm suffering from UDP packet loss during DNS query. So my web browser is too slow to surf internet nicely. But it worked very well when I tried a DNS query on TCP using dig command. However, I can't find some control switch to change to use TCP during DNS query. Is there a way to change it in Mac OS? Thank you.

  • SQL Server 2008 - cannot register default instance MSSQLSERVER

    - by Paul Moss
    Hello, I have installed SQL Server 2008 Developer on Windows 7 64 bit. In Management Studio I cannot register the default instance MSSQLSERVER, it cannot find it although the service is running. I get the message: Cannot connect to PHOENIX\MSSQLSERVER. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) (Microsoft SQL Server, Error: 87) However Management Studio does show the SQL Server 2005 Express instance (that was installed with VS 2008 Pro) which appeared as already registered. I an using Windows Authentication as I installed it in mixed mode. Any ideas would be appreciated, many thanks paul

  • Function keys require Fn modifer. How can I make them default?

    - by RickMeasham
    On my Dell Studio 15, the function keys, by default, do things like switch the radio on/off or change the brightness or sound. To use them as function keys I have to hold down the Fn modifier. I use function keys as function keys a lot more often than I want to change the volume or brightness. Am I missing an obvious setting somewhere in the control panel (Vista Uber Extreme Something)?

  • Programmatically sync the db in Django

    - by Attila Oláh
    I'm trying to sync my db from a view, something like this: from django import http from django.core import management def syncdb(request): management.call_command('syncdb') return http.HttpResponse('Database synced.') The issue is, it will block the dev server by asking for user input from the terminal. How can I pass it the '--noinput' option to prevent asking me anything? I have other ways of marking users as super-user, so there's no need for the user input, but I really need to call syncdb (and flush) programmatically, without logging on to the server via ssh. Any help is appreciated.

  • FileReference and HttpService Browse Image Modify it then Upload it

    - by user177787
    Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.
