Is there any API to let Narrator start reading from the specified position automatically, I have tried the way of setting the focus, it can't automatically go to the next line after reading.
I want to use these APIs in WPF or UWP, is there any?

I'm using the latest DWScript which has a TdwsDebugger component with it. However I'm not necessarily looking to provide debugging tools to the user - just visually show the current line number.
In the TdwsDebugger component, in its OnDebug event, expr.ScriptPos seems to provide me with this information. But I'm trying to figure out how to make use of this without actually "debugging".
How can I show current DWScript line number without implementing debugging?
When no debugger is active, there is no code actively maintaining any current "line" or other particular execution information, so that information is not available.
Basically, when not debugging, the script execution engine tries to avoid any debugging-related overhead, which includes maintaining current line number or sending debug events notifications.
I am using julius speech recognition for my application. I have one doubt regarding julius:
I have downloaded the latest version and was successful in using its lib and making it work. the problem I am facing is..once the app starts and I call the voice recognition function in my application...it takes the input from mic and displays whatever is said in the mic, but the function still continues to do so again and again. The control will never come out of that function. Here I am facing problem since the control is not returning back I am not able to proceed further. What I want is once the engine gets input from mic it should recognize and stop there.. which I tried to do by deleting the callback function but was unsuccessful.
Can anyone please guide me in this matter, what I need to do to get the desired output. It will be helpful for me.
As discussed in the same post on VoxForge:
You have a couple of choices: first to use the Julius -input control to get the sound data from a list of files (see the .jconf sample file), so that when the list (even if only length one) is exhausted then Julius stops. It is quite easy to record the voice input to a file and then feed the file into Julius. Second you can put a dialog manager in control. If you need more information on what a dialog manager does there are many posts on this forum on that subject accessible by a search.
The basic function of Julius is to start up and then keep on decoding input. When you get more experience you can run Julius as a server, and then tell the server to respond, not respond or shut down as required. It's more efficient than having Julius start and stop all the time.
When an avenue exists for a complex application to yield the required result by using an effective combination of options at run time, editing the application, while possible, might involve a lot of unnecessary work. The emphasis then shifts to passing the options correctly in whatever script is being used to access Julius.
I am transmitting and receiving data using aux cable and GNU RADIO between two laptops.
I have implemented DQPSK using PSK mod block.
The problem is that while receiving I have to provide a delay, some integer value e.g 0,1,2 etc.
It is different every time.
Is there a way to dynamically check for the right delay value or any other workaround to this situation?
I have written 'start.' at the start of data being transmitted and 'end.' at the end.
I have to give a demo for this project and I dont want to manually change the delay at runtime.
I cannot find the .cc file of file sink in GNU RADIO, I can change the C++ code according my requirement but there is no such file.
Below is the screenshot of the grc file on the receive side.
Any help will be appreciated.
Since there's no way for the receiver to know when the transmitter started transmitting, it decodes stuff before there's actually anything to decode.
In essence, you need some kind of preamble or so to tell your receiver when to start – side effect of having something like that would be that you could correct some things (the two sound cards don't share the same oscillator, which leads to a symbol rate offset, and a center frequency offset).
You basically added that framing - your start. and end. strings.
I cannot find the .cc file of file sink in GNU RADIO, I can change the C++ code according my requirement but there is no such file.
It's in gr-blocks/lib; however, you shouldn't modify the file sink. Really,
I'd recommend you take the time to go through the guided tutorials, use gr_modtool to generate a general block which has a state machine that looks for the bits of your start string and drops everything before and including those, and then passes everything till it sees the stop string. That all can be done with a single state machine, and a bit of python or C++ code.
How would I hook into a file that's currently in use by another program, which constantly writes out to it? Let's say, there's a text file with 10 lines. When I start my app it has to detect and read any content from there on everytime the writing program saves its content. Can this be done without a constant check on the filesize/date?
You could monitor the folder for changes using the ReadDirectoryChangesW API.
Keep track of the last position you read to, and when you receive a change notification for that file, read from there to the end of the file (as it currently stands).
An example of how to use the ReadDirectoryChangesW API is here:
Why does ReadDirectoryChangesW omit events?
Kinda similar to this:
Monitor files similar to System Internal's/Microsoft's FileMon/Process Monitor
sorry for this little bit strange title, didn't found a better one..
I've got the following situation:
I have a PC with an RFID reader connected via USB.
I now need a program which pops up when ab transponder was scanned the the RFID reader and shows the scanned value. (The reader just simulates keystrokes)
Problem: the value of the transponder is something like 0001230431, and I can't change it. (To prefix a hotkey combination or so)
So I have thought about using a global keyboard hook, check if three zeros where typed in, capture rest of data and when the 10 digits are complete, call the application through an automation object and show the number.
But I'm not very exalted about using a global keyboard hook. Many AV programs don't like them very much, they are not so easy to handle with Delphi and I guess that's not very resource-friendly for such a little task...
So I'm looking for an alternative solution...maybe somebody has an idea?
Big thx!
ben, you can use the RegisterRawInputDevices and GetRawInputData functions.
first you must use the RegisterRawInputDevices function to register the input device to monitor and then you can retrieves the data from the input device using the GetRawInputData function.
Check theses functions too
GetRawInputDeviceList retrieves the list of input devices attached to the system.
GetRawInputDeviceInfo retrieves information on a device.
Why not make sure the Delphi app with a text edit control has focus before the scan is done? Then the keystrokes will go straight into your Delphi app.
