Saving an array of sprite with filestream

hi I am looking for a way to save an array of sprite on the user drive and then read this array...
I saw method for saving text file. It quite simple... but it seems that saving an array is not very documented.
Any help tuto/ code wil be appriciated
Thanks

Hi so maybee it 's a better idea to convert spite to bitmapdata
var mySprite:Sprite = new Sprite();
var bData:BitmapData = new BitmapData(mySprite.width, mySprite.height, true);
bData.draw(mySprite);
var bmap:Bitmap = new Bitmap(bData);
and then save the bitmapdata ?
I will look at the bae 64 and join split method.

Problem saving 2D array to binary file

I am getting some strange results when trying to write a transposed 2D array of Unisgned 8-bit data to a binary file. Attached is an example program ("071026_ArraySave_Bug.vi") which demonstrates the suspicious behavior.
The program generates a small 2D array of U8 data, then saves it to two temporary files using two different methods.
1) Row-by-row: The 2D array is auto-indexed, and the indexed row is written to file at once (with the prepended size option disabled).
2) Point-by-point: Two For loops are used to auto-index each element and write it to file individually.
The saved files are then reopened and the data is read into two 1D arrays for display.
The bug occurs when the generated 2D array is transposed before being saved to file. In the point-by-point method, the data is always saved to the file as desired, i.e. by row or by column depending on whether the data was transposed. However, in the row-by-row method the data is incorrectly saved when the input data is transposed. Without transposing the array, the row-by-row results are correct.
Saving the array row-by-row is significantly faster for larger arrays, so this method is desired.
Note that the option to transpose the input data in the attached VI is performed using a case structure with a boolean constant ("Bug Control"). This is important because:
1) The bug does not occur if the boolean constant is replaced with a control.
2) The bug does not occur if the case structure is replaced with a "Select" node from the Comparison Palette.
3) The bug still occurs if the case structure is removed such that the array is always transposed (i.e. keep the True case).
For now, I have been able to circumvent the bug in practice by transposing the array and then passing it through a Select with a constant True (the False case uses the untransposed array). This allows the faster row-by-row method to be used without error, but requires new memory allocation for the transposed array.
I will appreciate any help that can be given regarding this problem, or simply confirmation that it is indeed a bug in Labview 8.5. It is worth noting that the same program did not produce any errors when run in Labview 7.
Thank you for your help,
David Viggiano

This is a known bug (CAR : 4DP855N3) , related to memory management. see this thread
If I remember well, Altenbach shown somewhere that forcing the transpose operation to produce a copy of the memory was a proper workaround.

Saving all action in database with triggers

Hi
I have oracle database 11gR2 . I dont have eny permission in datbase auditing,scn and ..... . I want to save all changes in database . i have 3 tables : tables , columns ,rowaction . in tables , saving name of all tables , in columns , saving name of all columns with tableid . I want to save old value and new value before and after insert in tables in rowaction table. So i should to create triggers for all tables in database automatically with procedure,that is run when insert or delete or update is occured . but I can not 'CREATE TRIGGER' in procedure .
Do you have any idea ?
Thanks

I have an idea that you should put this explanation along with the code of your original question on your previous thread:create trigger automatic
and STOP asking more questions about the same thing, otherwise you will be reported to the forum admin.
You already have one question related to your need to create triggers. DO NOT keep starting more questions about it.

Array of Cluster with event structure

Hi,
I am having Array of cluster with cluster having 1 String Control , 1 Combo box, 1 Led control and 2 Numeric control. In the combo box i am having two options to select ('Binary' and 'PWM').Whenever Binary is selected then Led control has be enabled and whenever PWM is selected 2 Numeric control has to be enabled.
Is there any way to do this??
Pleas help me...
Regards
Meenatchi

actually in my application, the front panel has to have 16 rows of controls (1 string control, 1 combo box, 1 Led control, 2 numeric control).so i planned to keep all those controls in a cluster and create one array.If i didnt so i will have 16x5 controls in my front panel and i have to put 16 event cases for each combo box to do the enable and disable of controls..
is there any simple way to do this..i have attached my front panel view

User event for array of waveforms with attribute

I have been transferring data in a Producer/Consumer architecture via User Events. The data consisted of an array of waveforms. When I added an attribute to the waveforms the code breaks with two errors about Create User Event: User event data type is unnamed or has elements with no names or duplicate names, and Contains unwired or bad terminal.
From reading the help on user events it is not clear that arrays are even allowed: "user event data type is a cluster of elements or an individual element whose data type and label define the data type and name of the user event."
From experimentation it seems that arrays of numerics and arrays of wavefroms without attributes work. A single waveform with an attribute can also be used. But an array of the same waveform with attribute leads to a broken run arrow. It also appears that I can put the array of waveforms with attributes inside a cluster and then create the user event.
Is this a bug, an undocumented corner case, or some "feature" that I do not understand?
Searching for User Event for Array of Waveforms generates some interesting, but mostly irrelevant results.

Another option would be typecasting, but it looks like you can't typecast a waveform. Variant to Data or Coerce to Type might also work, but I haven't tried.
I have also done the Flatten To String and Unflatten From String to send data around. It would be preferable to not need to do that though.

Oracle 8i array DML operations with LOB objects

Hi all,
I have a question about Oracle 8i array DML operations with LOB objects, both CLOB and BLOB. With the following statement in mind:
INSERT INTO TABLEX (COL1, COL2) VALUES (:1, :2)
where COL1 is a NUMBER and COL2 is a BLOB, I want to use OCIs array DML functionality to insert multiple records with a single statement execution. I have allocated an array of LOB locators, initialized them with OCIDescriptorAlloc(), and bound them to COL2 where mode is set to OCI_DATA_AT_EXEC and dty (IN) is set to SQLT_BLOB. It is after this where I am getting confused.
To send the LOB data, I have tried using the user-defined callback method, registering the callback function via OCIBindDynamic(). I initialize icbfps arguments as I would if I were dealing with RAW/LONG RAW data. When execution passes from the callback function, I encounter a memory exception within an Oracle dll. Where dvoid **indpp equals 0 and the object is of type RAW/LONG RAW, the function works fine. Is this not a valid methodology for CLOB/BLOB objects?
Next, I tried performing piecewise INSERTs using OCIStmtGetPieceInfo() and OCIStmtSetPieceInfo(). When using this method, I use OCILobWrite() along with a user-defined callback designed for LOBs to send LOB data to the database. Here everything works fine until I exit the user-defined LOB write callback function where an OCI_INVALID_HANDLE error is encountered. I understand that both OCILobWrite() and OCIStmtExecute() return OCI_NEED_DATA. And it does seem to me that the two statements work separately rather than in conjunction with each other. So I rather doubt this is the proper methodology.
As you can see, the correct method has evaded me. I have looked through the OCI LOB samples, but have not found any code that helps answer my question. Oracles OCI documentation has not been of much help either. So if anyone could offer some insight I would greatly appreciate it.

Before 9i, you will have to first insert empty locators using EMPTY_CLOB() inlined in the SQL and using RETURNING clause to return the locator. Then use OCILobWrite to write to the locators in a streamed fashion.
From 9i, you can actually bind a long buffer to each lob position without first inserting an empty locator, retrieving it and then writing to it.

Saving an array of multi-line text cells in a format that can be read in later

I can create an array of multi-line text entries that my program can then pick cells and compile them into a list of text.
I would like to be able to Save the array as a file, then change my program to read in the file.
If I use the Save Spreadsheet file vi, the data is corrupted by the carriage returns within the cells and the data read in is messed up.
Can someone recommend a way to save the array that preserves the carriage returns?

As far as I know, this cannot be done automatically with the basic VIs from the palletes. I would convert the [LF] into another group of characters (likely "\n") and then save the text array to a CSV file. Don't forget to escape any good "\" string with an extra "\. Regular expressions would work really well:
Just make sure you parse your entire array of strings with this.

Problem occurring when opening and saving files in AI SC5 with Windows 7

Hi, I ‘am a Graphic Designer and first time working in UAE Windows 7 is basically the only OS here. My PC is:
HP Elite 7000
Intel® Core™ i5 CPU 2.67GHz
4GB RAM
32-bit
Now to the problem, not that knowledgeable in IT stuff so here goes:
1. Problem occurring when opening and saving files in AI SC5 with Windows 7. (You will actually see a “Not Responding” word coming out while opening and saving files, whether small or large files)
2. Locked layers occasionally are moved accidentally.(Working on multiple layers is normal so we need to lock it specially the once on top. But there are times I still manage to select locked layers)
3. After typing and locking the text, pressing “V” for the arrow key shortcut is still added to the text that is locked. (After typing I lock the text layer with my mouse and Press “V” to activate the arrow key… yes the arrow key is activated but the text is still typing the actual keyboard pressed)
I’ve only use the brand new PC and installer for a month now. Not sure if this is compatibility issues or something else I’m not aware of.
Thanks in advance to people that will reply.
Cheers!!!

Well I’m still wondering if it is compatibility issues because I’m also having problem with Photoshop CS5. These 3 are all bought at the same time (PC, Illustrator and Photoshop installers). The problem I’m having in Photoshop is not that too important, every time I Ctrl+O to view files, all PSD are shown in white paper like icons, no preview, and saving as well.
Or I just purchased a corrupted or pirated installers… Adobe updates are done every time I’m prompted.

Saving images from LR Mobile with edits.

I'm having a bit of trouble saving images on my ipad with the current edits.
To me it seems I have to manually sync the edited image first, otherwise Lr just saves a JPG of the original image to my photostream rather than a copy with adjustments on it.
Am I missing something or is this the way it works?
Thanks for any insight.

Correct. As long your image is in Develop mode (same with presets and crop) and you would like to share from there you need to maually force sync your changes first. This is already logged as in internal bug. Thanks, Guido

Saving changed services in Automator with a new name.

Under SnowLeopard I could open an existing workflow, make some changes to it and save it as a new workflow service. In Lion there is no SAVE AS, so this procedure doesn't work.
I tried duplicating the workflow in the Finder and renaming it and opening it in Automator. The problem is; after making the changes and saving it, Services show it with the original name. That means both the original file and the duplicated/renamed file show up with the same name.
Is Automator creating an internal name for the file that can't be changed?
I had a service that moved files from one location to another. I created 5 duplicates of it and renamed them with the new location as part of I wanted to move file to. I made the changes to each with the new location as the place to move the selected files.
Now Services show six services with the original name and none with the new names.
Is anyone else having the same problem? I wish there were a way to force applications to do a SAVE AS.
I have also noticed that the DUPLICATE TO... doesn't give you an option to have to duplicated a new name.

For me the following works:
Open the servce you want to modify in Automator.
In Automator duplicate the workflow with File -> Duplicate.
Edit the duplicate.
Save it with File -> Save. You will be prompted for a new name.
Install the new service in ~/Library/Services and remove the old version.

Saving as .eps format compatible with Adobe Illustrator CS6 or earlier versions

saving as .eps format compatible with Adobe Illustrator CS6 or earlier versions??
does this mean cs6 or newer, or cs6 and older versions?

Don't use EPS anymore. It has been replaced by PDF or AI with PDF compatibility. If you use PDF use either a PDF/X-4 or a PDF without flattening transparency, so you will be able to use layers in other applications.
If you need to use a file in an older version you should save it as AI file in the version you want to open it. But it can happen, when you use some effects it can cause a flattening or rasterizing of a file or parts of it. So keep ALWAYS the file in the version you have created it.

Keynote document saved in icloud not updating with data from Numbers? is icloud the problem

keynote document saved in icloud not updating with data from Numbers? is icloud the problem.
If both files are held locally on the computer it looks like there is no problem however if you try and do it though icloud (ie your docs are saved on icloud) you dont get the "source" oprion besides the graph etc. Is this a but or a broken function due to the new implementation of icloud.

How do i send an array of clusters with variable size over TCP/IP?

Hi,
I'm trying to send an array of clusters with varible size over TCP/IP,. But I'm facing the following problems:
1) I need to accept the size of array data from the user and increase the size dynamically.
I'm doing this using the property node but how do I convey the new size to my TCP read?
2) I need to wire an input to my 'bytes to read' of the TCP read.
But the number of bytes to read changes dynamically
How do I ensure the correct number of bytes are read and reflected on the client side?
3) Is there anyway I can use global varibles over a network such that their values are updated just as if they would on one computer?
Will be a great help if someone posts a solution!
Thank you...

its no longer just the first four bytes that specify the length of the data, it could be more as my array of cluster can be pretty huge.
Instead of writing long and complicated sentences that make little sense, why don't you simply show us your code?
What does any of this have to do with xml strings???? I don't see how using a local variable as type input changes anything. The user cannot interact with "property nodes", just with controls. Please clarify. Once the array of clusters is flattened to a string you only have one size that describes the size of the data, no matter how huge it is (as long as it is within the limits of I32). Similarly, you read the string of that same defined length and form the array of clusters from it. How big are the strings? What is your definition of "huge"?
Here's is my earlier code, but now dealing with an array of clusters. Not much of a change. Since you have columns, you want 2D. Add as many diensions you want, but make sure that the control, diagram constant, and indicator all match.
The snipped shows for a 1D array, while the attached VI shows the same for a 2D array. Same difference.
