    I have a need to turn off other audio sources when I plan to use the Text to Speech API. The other audio may be in another process.

  • Is the RESTORE process dependent on schema?

    - by Martin Aatmaa
    Let's say I have two database instances: InstanceA - Production server InstanceB - Test server My workflow is to deploy new schema changes to InstanceB first, test them, and then deploy them to InstanceA. So, at any one time, the instance schema relationship looks like this: InstanceA - Schema Version 1.5 InstanceB - Schema Version 1.6 (new version being tested) An additional part of my workflow is to keep the data in InstanceB as fresh as possible. To fulfill this, I am taking the database backups of InstanceA and applying them (restoring them) to InstanceB. My question is, how does schema version affect the restoral process? I know I can do this: Backup InstanceA - Schema Version 1.5 Restore to InstanceB - Schema Version 1.5 But can I do this? Backup InstanceA - Schema Version 1.5 Restore to InstanceB - Schema Version 1.6 (new version being tested) If no, what would the failure look like? If yes, would the type of schema change matter? For example, if Schema Version 1.6 differed from Schema Version 1.5 by just having an altered storec proc, I imagine that this type of schema change should't affect the restoral process. On the other hand, if Schema Version 1.6 differed from Schema Version 1.5 by having a different table definition (say, an additional column), I image this would affect the restoral process. I hope I've made this clear enough. Thanks in advance for any input!

  • Add client-side events to ASP.Net custom control at runtime

    - by nw
    I'm building an ASP.net custom control that implements IScriptControl. I would like other users of my control to be able to assign client-side event handlers to the control. Unfortunately the JS generated by IScriptControl is always injected at the very bottom of the rendered page (see below), so any attempt to assign an event handler in the ASPX page fails because the code executes too early. ... <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(MyNamespace.MyControl, {}, null, null, $get("my_control_id")); }); //]]> </script> </form> What's the right way to assign an event handler to the instantiated control upon page load?

  • ChildControl of a childcontrol is null when calling from Main control

    - by Jan Schoenrock
    Hello I built a webusercontrol in asp.net which contains a databound dropdown. When I directly put this control into a webform it runs well. But if I try to add this control as childcontrol to another control at runtime Childcontrol childcontrol = new Childcontrol (); maincontrol.controls.add(childcontrol) , the dropdown of the childcontrol is not instatiated (is null) so that I run in an exception by trying to bind the data to the dropdown.

  • Can I trigger an Update Panel from a Drop Down list in a User Control

    - by Jisaak
    I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I know how to load the controls in the update panel, but I can't figure out how to get the user control to trigger the update panel. Any suggestions are very much appreciated.

  • multiple occurences of HandleCreated for a single control

    - by Asher
    I’m using control that needs to be register to asynchronous events. The events will be raised in the UI thread using the ISynchronizeInvoke interface implemented by WinForms controls I can’t register to the event at the constructor because it will allow calling the event handler before the control is fully created. during which calls to ISynchronizeInvoke are not allowed. Solution to that problem is to use the perform the asynchronous event registration from an event handler to the HandleCreated instead of registering from the constructor. however, this poses another issue, in some scenations the HandleCreated event is raised multiple times as result of change at the control state. For example, each changing of the “RightToLeft” property causes a WMCreate message that cause raising the “HandleCreated” event. How can I prevent the multiply times of event rising? Is there is another way to know when the control is created and display for the first time? I can keep a boolean flag in the HandleCreated, however it feels like a hack and I am wondering if there is a better way to handle this issue.

  • Jquery - add server control

    - by superexsl
    Hey, I'm having trouble with a custom control and adding it dynamically using JQuery. I've got the following code: $('.custom_control_div').replaceWith( "<div><cc:mycustomcontrol id='cControl' ></cc:mycustomcontrol></div>" ); This doesn't throw any errors, but doesn't work because I need to use runat=server in my custom control. However, if I add runat=server in the code above, no javascript is executed on the page (and jqueryUI no longer works). The custom control works fine when I add it directly to the page from design-time. Is there a way to add a control, with runat=server using Jquery? Thanks

  • An Interactive Console I/O Wrapper/Interceptor in C# - What is the issue?

    - by amazedsaint
    I was trying to put together an interactive Console interceptor/wrapper in C# over the weekend, by re-mixing few code samples I've found in SO and other sites. With what I've as of now, I'm unable to read back from the console reliably. Any quick pointers? public class ConsoleInterceptor { Process _interProc; public event Action<string> OutputReceivedEvent; public ConsoleInterceptor() { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo("cmd"); InitializeInterpreter(); } public ConsoleInterceptor(string command) { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo(command); InitializeInterpreter(); } public Process InterProc { get { return _interProc; } } private void InitializeInterpreter() { InterProc.StartInfo.RedirectStandardInput = true; InterProc.StartInfo.RedirectStandardOutput = true; InterProc.StartInfo.RedirectStandardError = true; InterProc.StartInfo.CreateNoWindow = true; InterProc.StartInfo.UseShellExecute = false; InterProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; bool started = InterProc.Start(); Redirect(InterProc.StandardOutput); Redirect(InterProc.StandardError); } private void Redirect(StreamReader input) { new Thread((a) => { var buffer = new char[1]; while (true) { if (input.Read(buffer, 0, 1) > 0) OutputReceived(new string(buffer)); }; }).Start(); } private void OutputReceived(string text) { if (OutputReceivedEvent != null) OutputReceivedEvent(text); } public void Input(string input) { InterProc.StandardInput.WriteLine(input); InterProc.StandardInput.Flush(); } }

  • Creating a KeyDown Event Handler for the Label Control

    - by j-t-s
    Hi All I'm sure you're all aware of the fact that the Label Control has no KeyDown handler (and why would it?)... Anyway, I'm in need of a KeyDown handler for the Label Control and would appreciate any pointers/suggestions to get me started. I've searched around but haven't found any info on creating my own Event Handlers for the Label Control. Can this be done is C#? Thanks

  • Registering a COM control during installation

    - by Curtis
    One of our applications needs to register a COM control during installation. If a newer version of that control is already registered, we don't want to overwrite it with the older. What are the Windows MSI install conditions I would user to control this? Or is there some other 'best-practice' method I'm not aware of? Thanks

  • Java Process.waitFor() and IO streams

    - by lynks
    I have the following code; String[] cmd = { "bash", "-c", "~/path/to/script.sh" }; Process p = Runtime.getRuntime().exec(cmd); PipeThread a = new PipeThread(p.getInputStream(), System.out); PipeThread b = new PipeThread(p.getErrorStream(), System.err); p.waitFor(); a.die(); b.die(); The PipeThread class is quite simple so I will include it in full; public class PipeThread implements Runnable { private BufferedInputStream in; private BufferedOutputStream out; public Thread thread; private boolean die = false; public PipeThread(InputStream i, OutputStream o) { in = new BufferedInputStream(i); out = new BufferedOutputStream(o); thread = new Thread(this); thread.start(); } public void die() { die = true; } public void run() { try { byte[] b = new byte[1024]; while(!die) { int x = in.read(b, 0, 1024); if(x > 0) out.write(b, 0, x); else die(); out.flush(); } } catch(Exception e) { e.printStackTrace(); } try { in.close(); out.close(); } catch(Exception e) { } } } My problem is this; p.waitFor() blocks endlessly, even after the subprocess has terminated. If I do not create the pair of PipeThread instances, then p.waitFor() works perfectly. What is it about the piping of io streams that is causing p.waitFor() to continue blocking? I'm confused as I thought the IO streams would be passive, unable to keep a process alive, or to make Java think the process is still alive.

  • Python GUI does not update until entire process is finished

    - by ccwhite1
    I have a process that gets a files from a directory and puts them in a list. It then iterates that list in a loop. The last line of the loop being where it should update my gui display, then it begins the loop again with the next item in the list. My problem is that it does not actually update the gui until the entire process is complete, which depending on the size of the list could be 30 seconds to over a minute. This gives the feeling of the program being 'hung' What I wanted it to do was to process one line in the list, update the gui and then continue. Where did I go wrong? The line to update the list is # Populate listview with drive contents. The print statements are just for debug. def populateList(self): print "populateList" sSource = self.txSource.Value sDest = self.txDest.Value # re-intialize listview and validated list self.listView1.DeleteAllItems() self.validatedMove = None self.validatedMove = [] #Create list of files listOfFiles = getList(sSource) #prompt if no files detected if listOfFiles == []: self.lvActions.Append([datetime.datetime.now(),"Parse Source for .MP3 files","No .MP3 files in source directory"]) #Populate list after both Source and Dest are chosen if len(sDest) > 1 and len(sDest) > 1: print "-iterate listOfFiles" for file in listOfFiles: sFilename = os.path.basename(file) sTitle = getTitle(file) sArtist = getArtist(file) sAlbum = getAblum(file) # Make path = sDest + Artist + Album sDestDir = os.path.join (sDest, sArtist) sDestDir = os.path.join (sDestDir, sAlbum) #If file exists change destination to *.copyX.mp3 sDestDir = self.defineDestFilename(os.path.join(sDestDir,sFilename)) # Populate listview with drive contents self.listView1.Append([sFilename,sTitle,sArtist,sAlbum,sDestDir]) #populate list to later use in move command self.validatedMove.append([file,sDestDir]) print "-item added to SourceDest list" else: print "-list not iterated"

  • WPF attach popup with a control

    - by viky
    I have a scenario where I am displaying a popup on my control. I am able to do this using PlacementTarget, Position, etc. My problem is when I resize the window and move it to somewhere else in the desktop, the popup remains stationary meaning it doesn't move with the control set as PlacementTarget. I was able to hide it in case of other window getting focus. But not able to attach it with my control. How can I solve this problem? Is there any other such control available?
