'Create masks from text' in turn computer black screen
I imported a ttf font in font book, then in the after effects CC and when I do the function 'create masks from text' using this text, the computer window becomes black and I am unable to read anything. The function still works with the indigenous texts well. Any ideas?
Thanks a lot for your help. I finally thought to it. After having tried everything you said and more, I feel a little ridiculous. All I ended up having to do was to change the font type breathe I used one in distress to the solid. Works fine now. Thanks again!

Digital loading data from text file for Test of numerical limit
I am a new user of TestStand 2014. Just downloaded the demo ran successfully the computer.dll tutorial & example "loading limits a File.seq text"; & is now trying to build my own sequence from scratch. I want to load a number from a text file using the property Loader. The file contains the following:
GGbeg
484
GGendMy hand sequence contains 2 markets (see attachment):
Charger property (which reads the text file & must store the number 484 in the Step.Result.Numeric variable, right?)
GG-digital-test (which should test the number 484 in Step.Result.Numeric as a Data Source, right?)
But when I run it, the measure indicates "0" for the value instead of "484". What I am doing wrong? Thank you in advance for your help!
George
Hi George,.
The text file must be in the format, includes no property magazine. Use the following in the text file to make it work:
GGbeg
Result.Numeric
GG-digital-test 484Value of the variable Value of the variable Value of the variable
GGendIn the Tools menu of the sequence editor, there are some 'Properties Export/Import' tool, which helps to create text files to be used with charger property stage. I highly recommend to create the new file using the tool and then edit the file to change the values.

Import data from text file of control of the ring.
Is it possible to import data to a text ring with labview control.
I have several definitions of register in the ring controls, but manual entry would take a lot of time.
Was wondering if there was more automatic way, I could read the values from a file.
Thank you
Jim
Using the first method gives you the ability to extend such that each column specifies a control of the ring if you need fill the multiple rings.
This example assumes that all of the three rings contain the same number of elements. If this isn't the case, you will need to create a Subvi, which removes the empty elements. [Edit - create a text file that contains a column for each ring, separated by a tab character.]

Convert data from text file to display for hex UDP transmission controls
Hello
I'm reading packets ethernet from a text file containing the actual hex data packets to then send these accurate return through a writing UDP hex data. I can't understand how to feed data into the function of writing UDP as real rather than characters ASCII hex data, as it does by default. I had the screen on the last VI before the writing of the UDP to "hexadecimal display mode" and if I manually type the hexadecimal values in the VI (hexadecimal string to binary String.vi - attached), then it passes the commands correctly. However,... when I fed the string of text in my text file data in this VI, it seems to be the substitution of this hexadecimal display on the VI input mode and the resulting entry in my UDP is still ASCII character mode. I tried to use a cast inside this VI, type... but that doesn't seem to work right. I have attached the main VI and VI which tries to prepare data before reading the UDP protocol. I've also attached an example of text file of data that I am an attempt of analysis.
Any help would be appreciated,
Thank you
Hi jsrocket,
the attached example should work as a transformation.

creating or reading text files based in compiled vi (.exe)
I did my .vi which contains features for reading/writing of settings and write log files. All goes well until I want to create an executable to distribute to colleagues who don't have labview development. When you run the .exe, it seems that I can't create or read .txt or .ini files. No idea how I can import functions open file in read/write/text to my .exe?
In fact, you try to create or read a file inside the executable. Of course, this won't work. Instead, use the Directory of the Application. It returns the folder that contains your project (in the LabVIEW environment) file or the folder of the executable (when in the execution engine).
So in your example, you just have to the Application Directory and the path to build to get the location of your settings.ini file.

I´d as read a SD card text file and display the contents.
The content of the file:
Archer 1 Archer 2 Archer 3 Archer 4
my code:
try { FileConnection con = (FileConnection) javax.microedition.io.Connector.open("file:///SDCard/test.txt"); if(con.exists()) { InputStream input = con.openInputStream(); StringBuffer buffer = new StringBuffer(); while(input.read() != -1) { buffer.append(input.read()); } showMessage("OutPut: "+buffer.toString()); } } catch (IOException e) { showMessage("Es ist ein Fehler aufgetreten."); }
And the output is:
11410411449101141041145010114104114511011410411452
What should be changed?
The problem is that you read the file in bytes and the StringBuffer does not accept the bytes as something that you can add. Therefore, it is interpretting the byte value read from the InputStream as an integer.
Here are two quick fixes on top of my head, I have not tested this code. One reads the InputStream using an InputStreamReader that can give you the contents of the file as an array of char that can be added directly to the StringBuffer. The second way still reads the file as bytes but then uses the StringUtilities class to add the array of bytes to the StringBuffer.
try { FileConnection con = (FileConnection) javax.microedition.io.Connector.open("file:///SDCard/test.txt"); if(con.exists()) { InputStream input = con.openInputStream(); InputStreamReader reader = new InputStreamReader(input); StringBuffer buffer = new StringBuffer(); char[] charBuffer = new char[1024 * 8]; int lengthRead; while ((lengthRead = reader.read(charBuffer, 0, charBuffer.length)) > 0) { buffer.append(charBuffer, 0, lengthRead); } showMessage("OutPut: "+buffer.toString()); } } catch (IOException e) { showMessage("Es ist ein Fehler aufgetreten."); } try { FileConnection con = (FileConnection) javax.microedition.io.Connector.open("file:///SDCard/test.txt"); if(con.exists()) { InputStream input = con.openInputStream(); StringBuffer buffer = new StringBuffer(); byte[] byteBuffer = new byte[1024 * 8]; int lengthRead; while ((lengthRead = input.read(byteBuffer, 0, byteBuffer.length)) > 0) { StringUtilities.append(buffer, byteBuffer, 0, lengthRead); } showMessage("OutPut: "+buffer.toString()); } } catch (IOException e) { showMessage("Es ist ein Fehler aufgetreten."); }

Cannot find the file error when loading data from text file to Oracle
Hello
I have an interface where I am loading a data from the text file to Oracle.
But when I try to do that I am getting following error.
ODI-1227: SrcSet0 (load) task fails on the source FILES SAPMM connections.

SAPMM is the name of the connection.
I use get_filename to get the name of the file and it is fetching a correct value as long as this variable is updated in the previous stage of this interface.

What would be the cause of this error?
Thank you
