Execution speed and Print Statements

I use so many "System.out.println" statements in my java program.
Will it reduce the execution speed of the application?

Everything that does something will make the application slower.
You should instead ask yourself if you need the print statements, and if the application is fast enough. You can also execute your application in a profiler to find bottle necks.

Net Due date differs in FBLl5N and print statement used

HI all,
we are using customer statement of accounts, which shows the document due date. Using payment terms 30 days and Due date is calculated from document date, but our statement differs in calculation of due date.
eg/:
Doc.date        DocDue date
31.07.2006      29.08.2006
23.08.2006      14.08.2006 and in the standard report FBL5n which shows as below
31.07.08        30.08.2006
23.08.2006      15.08.2006
Looking for ealier reply

Before I buy: speed and printer questions

I am looking to buy a new TC 500gb version to replace my linksys WRT54G. To upgrade the wireless router as well as start a backup system I have yet to ever initiate.
Two questions/concerns come up:
#1) After the initial back up to TC I understand there are hourly incremental back ups - Can that time interval be adjusted, and how long does that back up take (I do now add much data/ files to my main Comp usually) also during those incremental back ups does that affect the computer much, such as if I am playing an internet game, will I lag out while it is backing up every hour?
#2) Setting up a printer through usb port to be accessed by my home network. My HP C6180 all in one works fine being seen through the aged, but battle tested linksys, any reason it shouldn't work with the TC?
Thanks for any insights you might have in this regard.
I have cable isp access, My Main Comp is where the cable modem and TC would be, I have a G4, a G5 and a MBP scattered around the house accessing via wireless.

Hi Steven, welcome to the discussions.
After the initial backup (recommend that you use ethernet for this), TC will backup incrementally every hour assuming you will be using Time Machine. There is no way to alter this with Apple software, but a number of users have reported satisfaction with Time Machine Editor, http://timesoftware.free.fr/timemachineeditor/, which will allow you to schedule backups whenever you would like. This might be a good solution if you notice slow downs with other devices during a backup session.
Backups should be relatively quick, but be aware that very small changes in some programs (like Entourage, vmFusion, Parallels) require the entire database to be backed up, not just the small change that might have been made.
The printing question is the most difficult as the boards are busy with users who are having troubles in this regard. Perhaps some other users have used the same HP and can comment. Bear in mind that if your HP is compatible, only the printing function will work through the network. Scanning and other advanced functions are not supported.

Speed and printing problems with Tiger

Perhaps it is the number of photos i have stored in Iphoto (4000)? but my computer has become very very slow, especially when iphoto is open. Also, Internet explorer is unresponsive, and i find myself often having to use force quit. Are these problems unique to tiger or are they because i have so much saved on my hard drive?

Jeffrey,
It appears that you may have several issues occuring and it would help if you included as much info about your Mac as possible, i.e., which iMac, ram, hard drive capacity, amount used, processor speed, etc....

Difference between execution mode of Print preview and Print for Output

Hello,
Can anybody tell the difference between execution mode of print preview and print for an output (For eg. PO output or Invoice)?. I am trying to download some documents linked to Purchase order to desktop. The code is written in the same driver program for printing PO and it is executed after smartform function module is called. It works fine in print preview mode and it fails in print mode. The reason why download fails in print mode is that GUI not available (just found from debugging).
Any ideas?
Thanks
Anil

HI
try using any other printer and find out if you are getting the correct output. The printer needs to support Multiple Unicode encoding schemes like UTF 8, UTF 16BE, and UTF 16LE, plus special characters and logos, bi-directional text layout, and custom characters..

Speed within Cash and Bank Statement

One of our customers criticizes the speed at the booking of Cash and Bank Statements in SBO 2005A.
The more rows are added all the more slower becomes the processing of the current row.
This behavior appears extremely if the customer finalizes or saves the Statement.

Thanks Rahul.
I was actually trying to use the bank file import functionality on the Cash and Bank screen. When you press the Bank File button, it opens a browse window where you can select a text file to be imported. There has to be someone out there that has used this import function! Anyone?
Thanks,
Jose

Why is the difference in execution speed of the function "SetCtrlVal" between constant and changing values so small ?

In my large application (1 MB exe-file) I am continuously updating a lot of numeric controls with new values. Most of them do not really change their value. Within my search of improving the performance of my application I noticed, that there is only a small difference of the execution speed between a call of "SetCtrlValue" with constant values and calls with changing values. It runs much faster (25 times on my PC), if I get the actual control value with "GetCtrlVal", compare it with my new value an do a call to "SetCtrlVal" only if the current value and the new value are different.
My questions to CVI-developers is:
Isn't it possib
le to do this compare within the function "SetCtrlVal"
My question to all CVI-users is:
Does anyone have similar tips to improve the performance of CVI applications ?
I developed a small test application for this problem, which I can mail to interested users.

What takes the extra time is the redraw of the control. When you call SetCtrlVal we ALWAYS redraw the control. We wouldn't want to build in functionality to check if the value was the same because that would add additional time to the SetCtrlVal in every case. If you want to do it outside of the loop you can as you have done above. You have a few options. First, keep a previous value variable for the controls that you can use to determine whether to set the control value. I.E.
int oldVal = 0;
int newVal = 0;
if(newVal!=oldVal) {
SetCtrlVal(..., newVal);
oldVal = newVal;
Also, if you set the value of a control through SetCtrlAttribute instead, there is no built in redraw of the control (which is what takes all the time). Using SetCtrlAttribute
to set the value is very fast, but remember there isn't a built in redraw on the screen to display the new number.

Printer offline and error state

Just moved and installed printer HP 4200C series to my laptop with Window 8. Got the successful window. The printer shows offline (no drop down menu to chose online) and if I try to print, it says the printer is in a state or error. Tried suggestions from forum but no go.

Hello kokua,
Welcome to the HP Support Forums!
I see you are having some errors when trying to print, such as "Offline" and "Printer is in error state". I am at a little bit of a loss as to what printer you are using however, the 4200c is a Scanjet. Can you take a second look on the printer for its model number?
In the mean time, run the Print and Scan Dr on the computer, let me know what passes, fails, is fixed, etc.

Difference between "print" statements and "select" statements , TSQL

What is the difference between "print" statements and "select" statements when it omces to debugging and watching varibles in the stored procs .....

SELECT statement is part of the ANSI SQL language.
PRINT command is not part of the SQL language, it is used for debugging in T-SQL.
BOL:" Returns a user-defined message to the client.
A message string can be up to 8,000 characters long if it is a non-Unicode string, and 4,000 characters long if it is a Unicode string. Longer strings are truncated. The
varchar(max) and nvarchar(max) data types are truncated to data types that are no larger than
varchar(8000) and nvarchar(4000).
RAISERROR can also be used to return messages. RAISERROR has these advantages over PRINT:
RAISERROR supports substituting arguments into an error message string using a mechanism modeled on the printf function of the C language standard library.
RAISERROR can specify a unique error number, a severity, and a state code in addition to the text message.
RAISERROR can be used to return user-defined messages created using the sp_addmessage system stored procedure."
LINK: http://technet.microsoft.com/en-us/library/ms176047.aspx
The SSMS (client software) returns SELECT output to Results and PRINT output to Messages.
The SQLCMD -o (output file) option captures all outputs into one file mixed.

Is E-Print the same as AirPrint? I have an HP print and it states that I can print from tablets.

Sports Rep wrote:

Thanks again
I have a couple of HP printers, so I am somewhat familiar with this.
EPrint is not the same as air print. EPrint is HPs way of sending documents over the Internet to an Internet-connected printer. Air print, by contrast, is Apple's way of printing from an iPad or an iPhone over Wi-Fi. So, even if your printer is capable of "printing from tablets", it is not at all clear whether it is only air print or ePrint or both. The best thing you can do is check the list that was posted above and see if your model printer is in that list. If it is, you can use the air print function built into the latest iOS to print over Wi-Fi. On the other hand, if your printer is not on the list, you may still be able to print through ePrint. To do that, you should download and install the HP ePrint app that is available for free in the App Store. This will allow you to print over 3G to your wireless printer.

Your problem is not the interface and the form. You should care about the printing program only. You need to chage it the way there will be a part which can be looped at. Otto

How do you improve the speed of processing and printing of PDF from CAD in indesign?

I work for an engineering consultancy company and for a long while I have suffered with using PDFs files generated from AutoCAD when placed within an InDesign report. There are three issues that arise:
The files take a long time to process when preparing the InDesign report. (This is mainly in high quality preview mode)
The files take a long time to export to PDF
(The most annoying one) The files take a long time to process and print when sent from the PDF to the colour laser printer. So much so, a single page from InDesign that contains a PDF generated from CAD can take up to 15 mins to print.
I have tried converting the PDFs to jpegs prior to insertion into the InDesign document, but the quality and colour is dramatically reduced thus them useless. Is there any pre processing on the PDFs generated from CAD that I can do to reduce the impact that it has within InDesign and in the post processing?
We also get missing font warnings that arise from the inserted PDFs from CAD that may or may not be an issue. Your advice here would also be appreciated.
I would be the first to admit that I am not the most advanced user of InDesign though I am sure that my workflow could be improved to alleviate the situation.
Your assistance would be appreciated!

Thanks for your quick response.
I have tried both options you have recommended, but unfortunately the file size doesn't seem to be the issue. Most of our CAD files (except for when they contain raster backgrounds) are around 0.5-2Mb which isn't massive compared to some jpegs. The PDF optimization process does make a small difference to the file size but only in the region of perhaps 5% reduction.
If it helps the most awkward file I am using at the moment has this audit result, pre-optimization. This is typical of the CAD files produced by AutoCAD. As you can see the content streams take up the highest percentage that doesn't reduce that much even when the optimizer has all options engaged.
What do you think?

Fed up with speed and connection issues since exch...

Last Monday BT done some upgrade work at our local exchange. From that point onwards we have had speed and connection issues.
I use a Belkin G Router rather that the Homehub some that we can run a printer through it and that is plugged in to telephone socket via an extension. But before we blame any of that we have gone back to the Homehub2 so we could see the difference and there is very little.
We live in the countrside so broadband speeds are not great in any case. About 1.8 mg I guess but we have always had no problems. It was good enough for us and we could watch Iplayer.
I was getting fed up with drop outs and speed and yestereday an Openreach guy came out tested everything could not find any problems apart from speed. He made some calls and was told our band width had been capped. He had that removed and yesterday evening speed was a bit better.
Today just as bad again.

Hi Welcome to the forums
Your high noise margin will have a major impact on your speed
If you post the full stats from your router
For homehub – type 192.168.1.254 into your browser
Navigate to ADSL Settings or use the A-Z at the top right of the home page and scroll down to ADSL Settings and click on it

also post the full results from http://speedtester.bt.com/
Have you tried connecting to the test socket at the rear of the master socket
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

Print out all methods in program with print statements

Does anyone know how I would be able to print out all the methods in a program. For example:
class bd220p1 {
     public static void main(String args[]) {
          int lightspeedi,lightspeedm;
          long days;
          long seconds;
          long distancei;
          long distancem;
          // approximate speed of light in miles per second
          lightspeedi = 186000;
            // approximate speed of light in Kilometers per second
          lightspeedm = 300000;
          days = 1000; // specify number of days here
          seconds = days * 24 * 60 * 60; // convert to seconds
          distancem = lightspeedm * seconds; // compute distance in English system
          distancei = lightspeedi * seconds;// compute distance in Metric system
          System.out.print("In " + days);
          System.out.print(" days light will travel about ");
          System.out.println(distancei + " miles and");
          System.out.print(distancem + " Kilometers ");
}This code would produce 5 print statements for the 4 methods:
1 Main method
2 Print method
3 Print method
4 Println method
5 Print method
Does anyone know I can write the could to accomplish this? Right now I am experimenting with try/catch statements. Any help is greatly appreciated.

It seems to me the easiest approaches (other than using a tool someone else has already written) are:
1) Compile the source, and then use BCEL
2) Try some regular expressions; it won't be perfect but maybe you can tweak it until it's good enough.
3) Parse the source, and examine the parse tree.
1 and 3 will give you much better results, but require you to use outside libraries (or write a parser yourself).
You can do 2 using standard stuff from the JDK, but you may spend a lot of trial-and-error gettng the regexps right.
Which you choose will depend a lot on what the prof giving the assignment allows.
Also he may have some particular kind of solution in mind -- did he say anything?
If you're not sure what to do, ask your prof for clarification.
