Paint program with save function
Anyone know a way to make a paint program in flash 8 with
save function?
The paint area should be quite large so the current jpg
saving methods don't seem to work.
Any solutions for this?
You probably have to specify what exactly is the problem. Are
you referring to the data size that has to be transfered to a
server?

Problem with SaveAs function using random paths.
The Setup:
Part 1) I have a folder-level script that allows me to perform a SaveAs function from within forms. I do this as a way to save the document quietly in the background. The effect is that the file is overwritten by a copy of itself. The script is:
var mySaveAs = app.trustedFunction( function(oDoc,cPath,cFlName)
app.beginPriv();
cPath = cPath.replace(/([^\/])$/, "$1/");
try{
oDoc.saveAs(cPath + cFlName);
}catch(e){
app.alert("Error During Save");
app.endPriv();
Part 2) From within my documents, I perform the save by calling the function below:
function runSave()
{if(typeof(mySaveAs) == "function") {
var pathArray = this.path.split("/");
var myFileName = pathArray[pathArray.length-1];
var cPath = this.path.slice(0,myFileName);
mySaveAs(this, cPath, myFileName);
} else {
app.alert("Missing Save Function\n" + "Please contact forms administrator");
Part 3) I have several large forms that utilize an autosave to call the save function according to a time interval of 5 minutes, using:
app.setInterval(runSave(), 300000);
The Problem:
Part 1) The autosave feature works fine and it works silently in the background. However, I start to experience problems when I have two forms open at the same time. If, for example, I have a form from one folder open, and open a form from a second folder, the save feature will sometimes save the active document to it's original folder (as intended, overwriting itself and creating an autosave) or sometimes save to the second document's original folder. This leaves me with an updated (autosaved) copy of the document in the wrong folder, and a non-updated copy in the original folder. This seems to vary depending on which document I opened last and/or which document is currently active. Though I can't seem to find the right combination.
It's as thought the "this.path" is getting confused.
Part 2) Worse still, if the two documents have the same name, as is often the case with these forms, any incorrect filing when saving causes an overwrite of the second document and loss of data.
Part 3) To makes things maddening, this also happens at times when no second folder or second document is open. Instead, the misfiling saves the single, active document to a recently accessed folder. For example, I'll open a local folder and open a Word doc, close the doc and the folder, go to a different folder in a different root (a networked folder), open the form, and it autosaves to the local machine in the folder with the Word doc. So now not only do I have a non-updated copy in my correct folder, I have no idea where the updated copy was actually saved to until I come across it some time later.
Part 4) Again, worse still, the previously accessed folder might happen to be one that contains a document with the same name, and that document gets overwritten by the autosave. I'll have no idea that the form has been overwritten until I happen to open it some time later and see that it contains data from a totally different form.
What is going on and how do I stop it?
Adobe Acrobat X Pro on a PC.Thank you, that is helpful to understand. I'd like to keep it as 3 parameters, as all my documents currently output 3 to the trusted function. And I'd still like to keep the error catch, but I'm not sure why the previous trusted function from the tutorial is no longer working, so I just want to run this by you:
safeSaveAs = app.trustPropagatorFunction(function(theDoc,thePath,theFileName){
app.beginPriv();
var fullPath = (thePath + theFileName);
try {
theDoc.saveAs({cPath:fullPath});
} catch(e) {
app.alert("Error During Save");
app.endPriv();
myTrustedSaveAs = app.trustedFunction(function(theDoc,thePath,theFileName){
app.beginPriv();
safeSaveAs(theDoc,thePath,theFileName);
app.endPriv(); -
Recording midlet with save function
Im making a midlet that records audio and saves it to phone's file system. I get the application to run in emulator but when in phone (Sony Ericsson V800) i immediately get error Cannot create a DataSource for: null. Here is the code i'm trying to get to work: (i tried to change the file:///test.wav to file:///e:/test.wav but it didn't help. Also i got a version of this code without the save function but it doesn't work in phone either, it just says error.

// general purpose error method, displays on screen as well to output
private void error(Exception e) {
alert.setString(e.getMessage());
alert.setTitle("Error");
display.setCurrent(alert);
e.printStackTrace();
error = true;
}see this:
http://www.hcilab.org/documents/tutorials/AudioTest/index.html
I think the problem is the url passed to player "file:///test.wav"
I think you must read the file from the filesystem with jsr 75 api (Fileconnection etc.) and then make a byte stream in order to pass it to the Manager.createPlayer(). -
Upgrade Program with other function
hi disowned married woman i would like to know your name if
you want to deepen our conversation with interesting solution you
are for me a interesting subject to share my problem if is possible
naturally.
You are much kind one to respond answer to me a question
about document class PuzzleMain but i can't focus your person so i
can use your alias name >> " VarioPegged" <<
I'm very tired because i tried a lot of times to resolve my
problem but i recognize to have a low preparation to resolve these
disputes.
If i don't disturbe i would like to know how can create a
method that return a object Bitmap because i would like to upgrade
this program with other interesting modification like load
dimension of image and analize pixel image.
To realizate this modification i need to have object Bitmap
and than i can load pixel image with specific methods and
dimension.
I propose to you this question because if i can capture two
variable like dimension and resolution of image i can modify number
of colons and rows of picture otherwise it would be optimal to
resize images with fixed parameter so i can put in folder of images
, other picture with other optimal subjects .
Other question that i would like to propose to you is this,is
possible to know where i can to operate a MovieClip that stay into
another MovieClip.
thanks a lot generous Californian married Woman
kiss and Thanks a lot Luciano from Milano

TextLOL! I don't think I've laughed this hard in a while. I'm
sure the translation doesn't help the situation either :D
Luciano ... here in the States:
Guy = Man/Dude/Male
I happen to be a man/dude/male.
Now, what's a little disturbing (I think) is that you're
sending kisses to what you believe is a married woman in a public
Adobe forum!
OK, I'll help you anyway. You can easily use the
loader.content.width and
loader.content.height information to get the dimensions of
the image and then work from there.
I don't follow your question about a nested(?) MovieClip
though.
TS -
We are creating a fillable .pdf form for our company supervisors to use in the field as a daily report. My goal is to have a single Acrobat form that can be stored on their computer or on our FTP site that they can access to fill out a daily report. The issue we are having is that as soon as they start typing, the "save" button becomes active and if they are not super diligent they can end up overwriting the blank form. I need this to be bulletproof so we can get consistent reports each day.
How can I set the form up so that there is no option to accidentally save a filled out form over our blank "template" form?
Is there a way to add a button to the form and save it in a specific format while diabling any "save" functionality?
Please help. Any input would be greatly appreciated.
Thank you.Have you tried making the form Read-Only? Not sure that will do it, but worth a try. Actually I am not sure why the save is an issue, as long as they save to a new file name in the end. A filled out form can sometimes save time in terms of having name and such already filled in.

Problem with Save functionality for a Screen - Field
Hi Experts,
I have included a custom field with list box option to an infotype. The new filed displays the values based on the values selected in the standard field which has a list box option.
Now if we enter the transaction in change mode and change the standard field value without pressing ENTER and click SAVE button, it gets saved with an improper value in the custom field. The reason being the custom field values with drop down list is retreived only after we press enter (POV is triggered) after selecting a standard field.
Options tried:
I have included an error message (in PAI) to stop the values being saved, but the screen beomes disabled.
I have done my validation only on the custom field as there is no other possibility to validate any other fields on the screen (all are standard). Here the error message pops up and the field is in the enable mode, but it does not retrieve the possible values for the custom field based on my earlier selection for the standard field.( Because as POV does not get triggered in this case)
Ex. Std field value = USA
Custom field = United States of America
I changed the value in Standard field to = UK and click SAVE - It get saved
Now how to stop it from SAVING and let it know that there is an error in the custom field and it needs to select the right value from the list ie - United Kingdom.
LakshmiPerhaps a solution is to save the code value, not the text for the code, and only display the text. In this way, the database would have UK and when you re-entered the screen, a PBO module could obtain the text for UK for display.
Or, if you must store the text value instead of the code (seems redundant...you can look up the text anytime), an enhancement to the save to database logic to obtain the correct value from the current value of the code and save that to the database.... -
Need help with algorithm for my paint program
I was making a paint program with using a BufferedImage where the user draws to the BufferedImage and then I draw the BufferedImage onto the class I am extending JPanel with. I want the user to be able to use an undo feature via ctrl+z and I also want them to be able to update what kind of paper they're writing on live: a) blank paper b) graph paper c) lined paper. I cannot see how to do this by using BufferedImages. Is there something I'm missing or must I do it another way? I am trying to avoid the other way because it seems too demanding on the computer but if this is not do-able then I guess I must but I feel I should ask you guys if what I am doing is logical or monstrous.
What I am planning to do is make a LinkedList that has the following 4 parameters:
1) previous Point
2) current Point
3) current Color
4) boolean connectPrevious
which means that the program would basically draw the instantaneous line using the two points and color specified in paintComponent(Graphics g). The boolean value is for ctrl+z (undo) purposes. I am also planning to use a background thread to eliminate repeated entries in the LinkedList except for the last 25 components of the LinkedList (that number might change in practice).
What do you guys think?
Any input would be greatly appreciated!
Thanks in advance!Look at the package javax.swing.undo package - UndoableEdit interface and UndoManager class.
Just implement the interface. Store all necessary data to perform your action (colors, pixels, shapes etc.). Add all your UndoableEdits in an UndoManager instance and call undo() redo() when you need. -
LodePaint is an open source painting program similar to (Kolour)Paint but with more advanced features, more filters, soft brushes, alpha channel support, some HDR image support, etc...
The program is aimed mostly at pixel artists, icons, texture editing, "programmer's art", etc...
It can be downloaded here: https://sourceforge.net/projects/lodepaint/files/
Just unzip & run. It requires SDL, and hardware accelerated OpenGL to run.
Please try it out!

'Save' function inactive in user defined PF for CL_SALV*
Hello,
I've implemented OOPS ALV using CL_SALV* classes and defined a PF Status with 'Save' functionality copied from the Standard PF Status SALV_TABLE_STANDARD of the function group SALV_METADATA_STATUS.
However, the said SAVE function button is not active on execution of the report. I've checked the activation/visibility of the function using methods get_function(), is_active() and is_visible () but everything seems fine.
Please help.
Thanks,
Shalabh JainI don' think anything wrong with SALV Class. I tried the same by copying standard GUI Status "SALV_TABLE_STANDARD" to a Z GUI Status and it worked perfectly. I followed below steps
- Copy standard GUI status "SALV_TABLE_STANDARD" to "ZSALV_TABLE_STANDARD"
- Changed the Function code of SAVE button to "SAVE"
- Activated GUI Status.
- Attached the GUI status to the Z program
- Call method SET_SCREEN_STATUS
DATA : lv_sypfkey TYPE sypfkey.
lv_sypfkey = 'ZSALV_TABLE_STANDARD'.
TRY.
lr_table->set_screen_status(
EXPORTING
report = sy-repid
pfstatus = lv_sypfkey
set_functions = lr_table->c_functions_all ).
ENDTRY.

hi guys
I'm having some trouble making a small paint program with swing. It needs the following functions:
- choose a shape from a combobox(only line, rectangle or circle).
- set the filled checkbox to on or off
- choose a color with the JColorChooser when you click on the colorLabel
Then you can start drawing the shape you selected on the JPanel.
Could someone help me out ? I would really appreciate that :-)
Greetznoah.w's PaintLike2 program might get you what you want

Question
I want to save with <nowiki><alt><s></nowiki> in the program Exact Online. This function is not working. this is the first time that i use this program with firefox.
'''edit''', mod escaped the '''<nowiki><s></nowiki>''' to prevent line through questionSubmitted too soon... To change your accelerator key for accesskeys to Alt alone (or a different combination), you can change a setting using Firefox's about:config preferences page.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''ui.k''' and pause while the list is filtered
(3) Make sure '''ui.key.generalAccessKey''' is set to its default value of -1 (or right-click and choose Reset if it is not).
(4) Double-click '''ui.key.contentAccess''' to open a dialog box to change the value from its current default (on Windows, 5) to your choice of the following:
* 2 = '''Ctrl''' (Fx default on Mac thru Fx13)
* 3 = Ctrl + Shift
* 4 = '''Alt''' (IE/Chrome/Safari default on Win/Linux)
* 5 = '''Alt + Shift''' (Fx default on Windows & Linux)
* 6 = '''Ctrl + Alt''' (Fx default on Mac from Fx14) (Chrome/Safari default on Mac)
* 7 = Ctrl + Alt + Shift
This should take effect as soon as you OK the dialog, so you can experiment in a separate tab. Other combinations are available if you want to try them. See http://kb.mozillazine.org/Ui.key.contentAccess (inaccessible at the moment?) -
Hello. I am somewhat new to Java and I was recently assigned to do a simple paint program. I have had no trouble up until my class started getting into the graphical functions of Java. I need help with my program. I am supposed to start off with a program that draws lines and changes a minimum of 5 colors.

}If anyone could point me in the right direction of how to go about getting my buttons to work and fixing the button box, I would be greatly appreciative. I just need to get a little bit of advice and I think I should be good after I get this going.

Cant open PC Paint files with Appleworks paint program
I have been using the very simple Paint program that comes with windows. I have finally made the move and ditched the PC for something more stable.
When I try to import my .bmp pictures I used to work on into Appleworks it insists on opeing the Drawing program that has no "fill" etc. Even when I open the Paint program and then "force" it to open a .bmp only part of the picture is shown. I thought that a .bmp is pretty basic and common file type.
Does anyone know if Appleworks can handle .bmp files and if not what are other options. I didn't really feel the need to have a $170 paint program for what I am doing.
Hope you can help.
MichaelDale,
Thanks for your reply.
The problem is that I need to use the "fill" in the paint program.
I have actually just been able to get the file to load into Appleworks paint after reading about using the .pict save. All looked good untill I tried to fill. What happens now is that the fill is very chunky and does not bleed thru at all. This makes it pretty useless at the moment.
Same problem, with a twist now.
Looking forward to any further ideas.
Michael -
I have a site I do business with. They do not authorize passwords unless you are a dealer. I do not have passwords on an auto save function, as I want to type my passwords in each time for security. My password for this site will only work a short WHILE, AND THEN it will not be recognized by the site and I cannot get in.
Then I must contact the company to reset or clear it manually on their end so it can be reset. They always give me the SAME SETUP PASSWORD to use. I use it, then I RESET PASSWORD on my end. The computer seems to remember my user NAME AT least on my computer as it comes up once I start typing the username in. They SAY IT is a settings issue on my end. I do not have this problem on any other site even THOSE WITH higher SECURITY. I need to FIX the issue OR may LOSE ACCESS To the site as is very aggravating for them and they say other have had the problem but usually with chrome but never constantly.I am not that computer literate ,but my husband is an IT Security professor and textbook writer but says doesn't really know Firefox. I do not really want to store passwords on computer as have been hacked several times. He and I do not understand some of the terms mentioned. since it is not a problem with other sites it should be fixable. Please me help using terms I or my husband can understand without having to give Firefox all my passwords. I would be happy to set up something different just for this one site if I need to but need easy instructions. Have cleared the cookies before but it still happens. What setting do I need to change or set to fix this? the other questions that come up seem very different and do not apply. FF 22 now but happened w other FF versions.I'm having a little trouble understanding the part about your password having to be reset. Why is that happening??
Let's start with Firefox's settings:
(1) You can configure the password manager feature on this tab:
orange Firefox button (or Tools menu) > Options > Security
There is a checkbox to enable/disable the feature.
There also is a "Saved Passwords" button to review and remove any passwords you do not want Firefox to keep.
That tab also has a feature to set a Master Password so that no one can use your saved passwords without knowing the Master Password. You may need to exit Firefox in order for Firefox to ask for that again.
Related articles:
* [[Password manager - Remember, delete and change saved passwords in Firefox]]
* [[Use a Master Password to protect stored logins and passwords]]
(2) Site-specific permissions
If you want to use the password manager for other sites but NOT a particular site, you can configure that in the Permissions Manager.
In a new tab, type or paste '''about:permissions''' in the address bar and press Enter.
After the page loads, use the search box in the upper left corner to narrow down the list to the site you want to configure. Highlight the site on the left side, and on the right side, choose Block under Store Passwords.
(3) Form autocomplete suggestions
Separate from passwords, Firefox remembers entries you've made into forms (in most cases) and lists the matching ones below the form field in a drop-down.
To clear a suggestion, press the down arrow key to highlight it and press the Delete key.
To turn off this feature, see this article: [[Control whether Firefox automatically fills in forms with your information]].
To review and selectively edit or delete form history entries, you need an add-on. For example, you could try this one: https://addons.mozilla.org/firefox/addon/form-history-control/ -
How to open labview program with Quit Labview function inside?
Hi Any idea how to open labview program with Quit Labview function inside?
I forgot to add and set the condition of the type for this program.
If the program is an application, it would close straight away.
If it is still labview work, it will go straight to editing program without closing.
So I need to recover, open it and make some changes.
Clement
Solved!
Go to Solution.Put the VI in a project and open it from there, then it shouldn't autorun. You can use App.kind property of application to decide whether to close or not.
