Multiple Crystal Data Consumers in One Xcelcius File

We are trying to create a mashup of multiple different types of dashboards in one Xcelcius file. We've been able to do this successfully with multiple worksheets in our Excel file. However, we want to make all of our dashboards pull in Live data. The only way we've been able to get this to work with single dashboards is using the Crystal Data Consumer data connection. All of the other ones don't work for us. The problem we are having is that it looks like it only let's us use one Data Consumer data connection. Does anyone else have any ideas on how I can go about this?
The data source by the way is on a SQL Server 2005 database. We've been able to pull the data we need into our Crystal Report and then convert that data into dashboard form using the Crystal Data Consumer. We just need to do the same thing but do it with multiple dashboards.

Hi,
Try Using Live Office, it will allow you to bring multiple crystal report and you can have multiple connection in Xcelsius.

Writing multiple port data report into single excel file

I'm working on a STTE automation of an power management unit in which data's from 6 different channels are received from the unit which has to be tested and then verified and co-related with the digital and analog inputs given by the user. So my question is finally how to write all dese six channel's data to a single excel file with multiple work sheets..... Like channel-1 one in sheet1,ch-2 in sheet2 so on.... (these data's from 6 different are received from 6 different serial communication port.)
pls guide how to forward in the final report generation for abv mentioned requirement in labview

As nyc mentioned you will have to use ActiveX if you want to do exactly what you discribed but if you're new to LabVIEW that can be a big step.
In the VI you posted you write your data to xls file but the fact is that you use the write to text file function, so in the end your file is just a simple text file, and of course Excel can open this type of file.
Maybe you could have your VI to write txt files and then have another bit of code that would transfert the data in each text file to differnt worksheet in a Excel file.
Or maybe another option would be to write all your data to the same TDMS file (on channel per port) and then use the TDMS Excel Add in to generate an Excel file from the TDMS.
Feel free to ask more questions :-o

How can i log two (almost equal) data streams into one spreadsheet file?

Hello,
My problem is (as stated above) that i would like to log data obtained from 15 current-sensors and data obtained from 15 pressure sensors into one spreadsheet file. The idea is to put them next to eachother (preferabley pressure current sensors 1, pressure current sensors 2, pressure current sensors 3 etc.).
Next to that I'm having difficulty logging certain constraints into a separate spreadsheet file. I.e. I've placed a maximum value constraint on my datalogger and I wish to log the data that has surpassed the max. constraint seperatly from the main logging file (see above) and (of course) preferably with the associated sensors. I would be extremly grateful if someone
out there could help me with this problem becouse when I've fixed these problems my internship will finally have come to an end (and i NEED a vacation). Thanks in advace;

Shouldn't be too difficult. You would obviously have to have some form of test to see when your data has gone out of the specified range. You could then have this secondary logging process inside a case structure. You could innitialize this second file with the same header info. This is easiest if you go ahead and log all the sensor values into this new "surpassed" file if any of them are over. Otherwise, you will have to enter space characters ahead of the sensor values to ensure that the columns line up. You can create a string constant with a bunch of space characters and just use it over and over as necessary.

How to use multiple Spry Data Sets in one page

I'm using two spry data sets in one page. When I add the first spry data set to my page everything runs OK, When I add the second spry data set to the page the first data set stops working. Does anyone know what the problem is?
This is how I have my data sets listed.
var ds1 = new Spry.Data.HTMLDataSet("/accounts/tower/list.php", "list");
var ds2 = new Spry.Data.HTMLDataSet("/accounts/tower/numvisits.php", "chart");
Thanks, let me know if you need more information.

Good News!
There is nothing wrong with what you have shown.
Bad news!
The problem could be in that part that you have not shown.

Writing multiple BLOB (PDF) records into one PDF file

I currently have a procedure that writes an individual BLOB pdf row and outputs it to a PDF file, however I would like to write multiple BLOB rows into one PDF.
Oracle version:10g R2.
Does anyone know whether it is possible to do this?
Here is my code, I was hoping to use a cursor FOR LOOP to read the BLOB records. The BLOB records do successfully load into a new PDF file, however when you open it the PDF only the first page is viewable. I am assuming the issue is to do with the PDF format rather than writing the data out to the file. I.e. the Page numbers etc.., incorrect formatting of the PDF?
declare
-- Test statements here
b BLOB;
amount BINARY_INTEGER;
file_handle UTL_FILE.FILE_TYPE;
l_pos INTEGER := 1;
l_blob_len INTEGER;
l_buffer RAW (32767);
l_amount BINARY_INTEGER := 32767;
file_name_ VARCHAR2(200);
pattern_id_ VARCHAR2(200) := '5555555';
pdf_path_ VARCHAR2(200) := 'PDF_OUT';
cursor get_blob_recs is
select pdf from mds_remote_pdf_tmp;
BEGIN
file_name_ := to_char(pattern_id_)||'.PDF';
file_handle := UTL_FILE.FOPEN(pdf_path_,file_name_,'wb');
FOR rec_ IN get_blob_recs LOOP
l_blob_len := DBMS_LOB.getlength (rec_.pdf);
l_pos := 1;
WHILE l_pos < l_blob_len
LOOP
DBMS_LOB.READ (rec_.pdf, l_amount, l_pos, l_buffer);
UTL_FILE.put_raw (file_handle, l_buffer, FALSE);
l_pos := l_pos + l_amount;
END LOOP;
END LOOP;
UTL_FILE.FCLOSE(file_handle);
end;
Any advice would be greatly appreciated.
Regards,
David.

I guessed there was more to a PDF file format than just amending the BLOB objects!. I think I'll have to create a function with an IN param containing the PDF file list, and invoke a Java class to merge the PDFs in the OS.
My requirement is to record the history of when a hand written form was completed. E.g. a user might complete half a document one day, and the rest of the document another day, therefore I want one PDF with two pages of the same form at different stages of completion. These forms are currently being created as two separate PDFs, and the problem is I am restricted to displaying only one PDF!
Thank you.
David.

Multiple sites, and domains, only one log file is working

I have a custom install of Entropy latest version for apache 1.3
OS X 10.4.5 on an Xserve dual g5
Everything is running fantastic save for one thing.
The sites that I have set up for multiple domains and multiple websites only the site that is in the top of the List in Server Administration under Web and so forth... I have the top site (which is our own site) and the others under that gain no hits and stats information because everything is being logged under the top site. Does this make sense?
I use Awstats to generate information for the various sites but only the top site generates hits and it gets the information for everything.
I am using entropy because I needed a level of security to avoid spammers on our guestbook and contact forms and entropy has the ability to use turing test.
Our various sites are now requesting custom stats and information but cannot get this to work. I have set different file names for each of the sites logs both hits and error log.
What do I need to check and what information can I supply to you from my custom install that will help you help me get this working.
Thank you everyone for your help.

Add me to the "me too" list.
Could it have anything to do with the difference between a "local host aliases" and "virtual hosting"? Or is that just related to Mail service?
Maybe it belongs in another thread, but what are most folks using for log analysis? I've got 40 or so virtually hosted domains that I'd like to track so I can kill the sites that aren't doing my company any good...

How can I save multiple separate edited images from one original file?

I shoot NEF raw images and am getting used to the way LR5 editing works without altering the file in any way. Now I wonder how I can create multiple edited images this way.

Thank you, that was spot on. It will help a great deal right now as I am taking multiple crops from shots of the ocean looking for something striking.
I doesn't seem to matter if I take a copy while editing or before I start editing, I can always reset the original and start again.
Is it possible to rename the copy? I had a look around here and in LR Help but rename doesn't come together with virtual copy.

Read multiple DAQ data packet in one WHILE iteration

Hello,
I am looking for a solution to the following problem :
I am using a PXI-6132 to acquire an anlogue waveform, the DAQ is trigerred by the falling edge of an other analog waveform with the same theoritical frequency. What I would like to do is to acquire for example 30 samples after the trigger, then store this data in the on-board memory; then wait for the next falling edge (my trigger) to acquire another 30 samples batch and, after let say 5 acquisition events, transfer this data form the on-board memory to my host computer memory to be read by a classical "Read fonction" in one itération of my while loop. I tried a lot of solutions (for ex. by setting the on-board memory buffer size to 150 before entering the while loop) but the read function still reads only 30 samples in one iteration. Is it possible to find a solution with the classical : create channel, timing function, trigerring function then a read function in a while loop or do I need to use a more complicated structure ....
Thanks in advance for your help

Stream multiple bitrates but only save one to file?

I have configured FMLE to stream 2 bitrates to Ustream.
For 'Save to File' the manual says add "%i" to name which saves both bitrates to disk.
Is their a way to choose one bitrate to save to disk?

Hi Kosta,
I think that the counts only get updated if you automatically sync your iPod. If the iPod is on manual update the count shouldn't change.
Shouldn't be too hard to test but I'm not near my iPod at the moment.

Scanning multiple pages as one pdf file

Hi Im using a Macbook Pro 10.9.5 and am trying to scan multiple pages and save as one pdf file. One suggestion is to use image capture. However, when I try to do this it says no camera or scanner is detected but it does not give me an option to copy multiple pages. Any suggestions. I have tried lowering the resolution but still have no luck.

Hi SusieG1026,
Are you sure to select file type Correct as text in image capture window?

Save multiple waveform graphs and data in one Excel File

Hi there,
I managed to save data from waveform graph into excel file and saving the plot into excel but individually. I'm aiming to save both the data and the plot in an excel file. May I know how do I do it? I've tried using the Write to Measurement File vi and also the invoke node of the waveform chart but it's still not giving me what I've wanted.
The above was only for one analog input channel and I have 2 analog inputs each with their respective sets of data and plot. Is there a way to execute the data and plot of one input in one worksheet and another set of data and plot in another worksheet, all in one excel file?

Hi there;
I would recommend using the Report Generation Toolkit; it is the easiest way.
You can use either the Report Express VI or the Appi to save all your data in both formats
Greetings

How do I scan multiple pages into one pdf file using the PIXMA MG7520 on Windows 8.0? Please help!

I recently received a PIXMA MG7520 for a gift. It works great with my lenovo laptop/tablet running on Windos 8.0. The one drawback to the HP all-in-one that it replaced is it does not have an ADF. That being said, there must be some way to scan multiple pages into one pdf file. I need help figuring thing out. Thanks in advance!
Solved!
Go to Solution.

Hi mdtolbert54,
There is a program that comes with the printer called the IJ Scan Utility that can assist you with scanning multiple pages into a single PDF document. To do this, please follow these steps:
1. On your keyboard, press the Windows key.
2. Start typing IJ SCAN UTILITY. The search window opens as you type. Once the IJ SCAN UTILITY is displayed, please select and open it.
3. In the Canon IJ Scan Utility window that opens, click SETTINGS.... in the bottom right of the window. The Settings dialog box appears.
4. Click the DOCUMENT SCAN option on the left pane of the window.
5. In the SAVE SETTINGS section of the window, you will select the save format and location of the document you are about to scan.
a.) In the FILE NAME field, specify the name you would like to give the file. By default the filename will begin with IMG; you can remove IMG and change it to whatever you would like to name the file.
b.) In the DATA FORMAT field, use the drop-down arrow to select the PDF (Multiple Pages) option.
c.) In the SAVE IN field, please navigate to the area where you would like the file to be saved once it is scanned in. By default, the file will be saved in the MY DOCUMENTS folder.
6. Once all settings have been selected, click the OK button at the bottom of the window to save the changes. The IJ Scan Utility main screen appears.
7. Click the DOCUMENT button. Scanning starts. Click the CANCEL button to cancel scanning if needed. Scanned items are saved in previously selected folder location specified in the SETTINGS... window.
If you find that you need advanced scanning options such as adjusting resolution, brightness, contrast, saturation, color balance, etc. in addition to the options selected above, please click on the SCANGEAR button on the IJ Scan Utility Main screen, then adjust the items as necessary.
Once the items above are set for document scanning, in the future, you will only need to launch the IJ Scan Utility, then press the DOCUMENT button to perform the scan (unless you want to make changes to the settings).
Hope this helps!

Read multiple files and save all into one output file(AGAIN)

Hi, guys
I need your help for reading data from multiple files and save the results into one output file. When files are selected from file chooser, my program read the data line by line , do some calculations and save the result into the output. I made an array to store input files and it seems to be working fine, but when it comes to SaveFile() function, issues NullPointException message.

Sorry about the long lines.
As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
Does anybody have an idea to solve this?
Thanks a lot!!

you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
your code is doing too much..and hard to follows..
1. get the selected files
for each selected file
process the file and return the result
write out the result.
/** close the precious resource */
public void closeResource(Reader in){
    if (in != null){
        try{ in.close(); }
        catch (Exception e){}
/** get the total number of line in a file */
public int getLineCount(File file) throws IOException{
    BufferedReader in = null;
    int lineCount = 0;
    try{
        in = new BufferedReader(new FileReader(file));
        while ((in.readLine() != null)
            lineCount++;
        return lineCount;
    finally{ closeResource (in); }
/** read the file */
public void processFile(File inFile, File outFile) throws IOException{
    BufferedReader in = null;
    StringBuffer result = new StringBuffer();
    try{
        in = new BufferedReader(new FileReader(inFile));
        String line = null;
        while ((in.readLine() != null){
            .. do something with the line
            result.append(....);
        writeToFile(outFile, result.toString());
    finally{ closeResource (in); }
public void writeToFile(File outFile, String result) throws IOException{
    PrintWriter out = null;
    try{
        out = new PrintWriter(new FileWriter(outFile, true)); // true for appending to the end of the file
        out.println(result);
    finally{ if (out != null){ try{ out.close(); } catch (Exception e){} } }

Splitting data equaly from one .mdf to several .ndf files

Hi all,
Situation:
We have a db with 1 TB of data in one .mdf file (sql 2012).
For better performance we want to split this file up into 4 equaly big data files on different drives.
1st guess:
Well I thought that's pretty simple, I just add 4 datafiles (.ndf) on different drives, empty my existing .mdf and drop it finaly.
Well the problem with this is, you cannot delete your .mdf file because it holds metadata (catalog) for your db.
Solution:
- I added 3 more datafiles (.ndf) with 250 GB size each, autogrow disabled, on 3 additional drives (no new filegroup)
- DBCC SHRINKFILE (your_logical_mdf_file, EMPTYFILE)
(this gives you an error because there is not enough diskspace to split the 1TB .mdf file into 3 x 250 GB .ndf files, but it splits your 1 TB file equaly to all your 4 db files)
- shrinked my .mdf file and adjusted filesize and autogrow settings for all 4 db files
Remark:
Just keep in mind that moving 1 TB of data around takes a while and you better do this in a not so busy time...

Neha,
I don't see any advantage of the IO with filegroups.
We don't want to deal with what object should be in what filegroup, (most of the time we maintain 3rd party software/dbs) just want to get better performance by splitting data into more then one db file.
acki4711
You could benefit from performance by splitting data in upto 4 or 8 files and each file on a different drive.
How are the underlying disks configured, do you know? Otherwise, if all of these volumes are carved out of a single lun then there won't be a performance gain that you are looking for. Also, please enable TF 1117 for uniform db file growth once you size
the files to be of equal size.
Note: You may want to test the emptyfile option on your .mdf file, as it may not be straightfoward.
HTH
Hello AlliedDBA,
There is no benefit by splitting database files on different disk drives if your Underlying hardware is RAID 10 or RAID 5 you can achieve performance benefit.Daa to data files are written in Round robin fashion and you dont have any control over it.
Please dont enable any Trace flag.I am not sure what could be solution beacause IMO you anyhow require space
Please mark this reply as the answer or vote as helpful, as appropriate, to make it useful for other readers
Hello Shanky..
Thanks for your feedback, but, I still stand by my suggestion. I see you are opinionating here, so please post some facts to back your claims that 1. No advantage of having multiple files 2. Not sure why your are scared of the term Trace flag but your
statement "IMO anyhow require space" lacks clarity..What is the relationship between space and trace flag??
