I need this vi: cdEx_online state regulator.vi
Hi
can somebody help me, really in need of this vi
cdEx_online state regulator.vi
thanks
meiza,
All that this VI does it calculate the LQR gain on-the-fly, discretize and implement the controller.
This VI has been removed from later versions of this toolkit, but you can have it if you install Control Design Toolkit 1.0 or 2.0.
The "cdEx_" is used in this toolkit to mark example VIs and saw no need to keep it around. However, why do you need this VI? Do you have an application that uses it?
Thank you for your feedback

Tried opening a file in library and it states can't open database with library name? It says Relaunch then will not open? and Blocks me completely from Aperture. I have to go to Finder to Rename it? I need this file how do I get it to open?
Aftershotz,
You're going to have to give a bit more information.
What do you mean by "opening a file in library?" There is no function of Aperture to open files -- you can open (switch) libraries.
You'll have to be more specific about error messages, too. Perhaps some screenshots would be useful to diagnose your problem. "Can't open database with library name" is not enough detail about what Aperture is really telling you.

I have a Dell PC. This Software Updater comes on saying I need to update . I states that I urgently need this update! Norton says okay. I go ahead and approve. Then it start...updater connecting to update server... and it goes on an on and on. until I turned it off.
I have done that several times. I have even left it on to go on about my business. But apparently it hasn't unloaded anything because it keeps coming back on when I start up my computer.
Is this your updater?If there are problems with updating then best is to download the full version and uninstall the currently installed version.
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox. -
Need this formula to look back 2 full years
In the following code, we are looking to show all records, where, the part# had no sales for the 2 month period selected by the user. But we also do not want to show this part if the current onhand balance is o, and also, we do want to show when was the last sale for this part. THe change i need is that the code here will show the last sales for past year only of calender year. I would like it to show 2 years back, meaning 2 full years from current date. I think i need to have an OR statement here and {SUMPRT.IQYER#} = {?Year} but not really sure. this is a crystal reports formula.
{PARTINV.IEQOH#} <> 0.00 and ( if {?Month}=1 then (({SUMPRT.IQA01} =0 and {SUMPRT.IQYER#} = {?Year}) and ({SUMPRT.IQA12} =0 and {SUMPRT.IQYER#} = {?Year}-1)) else if {?Month}=2 then ({SUMPRT.IQA01} =0 and {SUMPRT.IQA02} =0 ) and {SUMPRT.IQYER#} = {?Year} else if {?Month}=3 then etc...Hi Paul,
This formula is pretty confusing because I can't decipher which fields relate to what. I think though you may be overthinking the formula.
It looks like you are evaluating each month of the year individually. Instead of using nested IFs, have each month as a separate statement. Better yet, use a case statement like:
{PARTINV.IEQOH#} <> 0.00 And
Select {?Month}
Case 1: (({SUMPRT.IQA01} =0 and {SUMPRT.IQYER#} = {?Year})
and ({SUMPRT.IQA12} =0 and {SUMPRT.IQYER#} = {?Year}-1))
Case 2: ({SUMPRT.IQA01} =0 and {SUMPRT.IQA02} =0 )
and {SUMPRT.IQYER#} = {?Year}
Default: etc...;
Separating the months into a Case or independant IF should get you your results.
Thanks,

Need help with the session state value items.
I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Again on "call to this must be first statement in constructor"
Hi, I've spent the last hour reading tons of docs & threads about the "call to this must be first statement in constructor" problem, but I still cannot work it out.
Here is the code
public Orologio(String s)
StringTokenizer exploder=new StringTokenizer(s,":",false);
this(Integer.parseInt(exploder.nextToken()),Integer.parseInt(exploder.nextToken()));
}Well, I know this..() must be the first line in the method, but I need to parse my input string before passing the parameters to the Orologio(int,int) constructor!
Thankyou!You could define an initialization method:private void init(int a, int b) {
... your initialization code that was in your constructor...
public Orologio(String s) {
StringTokenizer exploder=new StringTokenizer(s,":",false);
init(Integer.parseInt(exploder.nextToken()),Integer.parseInt(exploder.nextToken()));
public Orlogio(int a, int b) {
init(a, b);
}However, make sure it is the responsability of this class to handle String as constructor parameter. Maybe you should force the client to tokenize the string and provide integer values to the constructor (and then get rid of the Orologio(String s) constructor.) -

Is this possible in one statement
I'm able to do this progamatically using two statements and a loop. Just curious if it's possible to combine it into one. Basically if asset_managent = 'Y' then a new line needs to be inserted for each quantity. Each new line will have a quantity of 1. The old line's quantity needs to get updated to 1 as well.
distrib_tbl
key_field(PK) line_nbr(PK) asset_management quantity
abc 1 Y 5

key_field(PK) line_nbr(PK) asset_management quantity
abc 1 Y 1
abc 2 Y 1

I am unable to open my Photoshop program after installing the entire Creative Suite: Premium Production 6. All other programs work, but with Photoshop it says that it "Could not open a scratch file because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock the file." Then I select "OK" and the next message comes up "Could not initialize Photoshop because the file is locked, you do not have the necessary permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock this file. I installed all of the programs on the same day from a CD. I need this fixed immediately.
I am not interested in switching to Creative Cloud, so don't even suggest it. I spoke to Mashmi (or something to that effect) on the "Support" Chat and there was absolutely no support. Useless actually.
Thanks in advance.Could not open a scratch file because the file is locked or you do not have the necessary access privileges. (…) | Mylen…

I have worked with iMoive a ton and have never had an issue. I consider myself pretty computer savvy. This new iMovie is not my friend. It will not let me share my new video. I click on the project and click "share" like it says but I don't receive any further prompt. It literally does nothing. I tried the drop down menu and I see the "share" with an arrow indicating there are options but no drop down menu appears. I need this video by tonight to submit for work. HELP!
I got it to share! No reloading iMovie!
I do not have Mackeeper on my laptop
I have the movie files on an external hard drive
1. Close out iMovie
2. Eject the external hard drive
3. Start up iMovie
4. Plug in the external hard drive
5. Go into finder and double click on the folder containing the movie
6. Select the movie as if to edit
7. Share it!
I hope this works for you too -
I just bought a new mac mini and an external DVD burner. I want to burn a DVD video and it will not play on the TV but only on the computer? Need this figured out for tomorrow. Can anyone help me?
Congratulations on the new Mini. Are you saying you tried burning and it does not play, or do you want to burn it only for the computer to be able to play it?

When the window opens to ask if I want to save or not comes up it does so for WORD documents just fine, however, for PDF documents it never asks (it used to). Now it just automatically saves them without asking. I need this changed. I went into applications and changed the setting to always ask but it still is just saving, them no window pops up asking what I want firefox to do with the file like it does with a WORD document. IF I cannot get this resolved I will not be able to continue using firefox. I teach and I have students submitting articles etc in pdf format, I cannot constantly save all pdf files. I just want to open them, review them and then move on. There must be a way to change this so that the window asking what I want firfox to do with the pdf files opens.
thank you,
kkwrightDeleted it, restarted it. tried it again. no change. repeated the whole cycle. no change. thinking about uninstalling and reinstalling, but that won't reallyk change the settings.

I installed a new SSD drive in my computer and now Adobe Creative Suite Web Premium says I don't have a license. I have license. It was very expensive. I am disabled now, and I need this software working. Adobe Acrobat has been a primary tool for accommodating memory problems after a brain injury. (A car ran me down while I was out getting exercise.) I installed the SSD because I needed my management of PDF files to run faster. I called tech support for help when the software first stopped working, but they needed me to give them a number from my original disks. Because of my disability, I've been having someone come in to clean, and the shelves where I kept my software packages were cleared. I've been hunting for them ever since, but I can't look for them myself for very long at a time. Today I finally found them, but now I can't seem to contact tech support. What happened? I don't want to delete my old files because I need the setup to remain unchanged, because I don't do well with changes. I think all I should need is to have someone located the license file on drive E: and move it to wherever it is needed on the SSD drive, but I don't know what to look for.
Tech support is not normally available on weekends. You should contact them as soon as the weekend passes and pick up where you left off with them.

I have had Photoshop for several days now and for the few days I have tried I just can not install anything what-so-ever. I have taken all of the suggested steps and it didn't do anything to help, it still had some sort of error. I have contacted Adobe, but haven't heard anything.
I really need this Photoshop for a project that needs to be completed before February. I do not have time or money to buy or exchange for new one.
I really need help I just don't understand what is going wrong and I really need help!I think i know what the problem is here. You have downloaded the Apple MAC version and trying to install on a Windows system. If this is so then you will get this error message.
Try to download the Windows version and then see if it works this time. Windows and Apple MACS are two different types of operating systems. Windows is widely used in the market place because of Microsoft's Marketing expertise while Apple MACs is used in the printing industry.
