Inputting from and Outputting to Excel Spreadsheets (.xls): How is it done?
Is it possible to input from and output to .xls files in a Java program?
If so, can you point me in the right direction/show me how?

(Think java.io except with spreadsheet files instead of .txt files.) I already answered that question.
I need to accomplish this without the use of a community-created library.That's a bizarre requriement. Why?

Okay, [here you go|http://lmgtfy.com/?q=communication+between+StarOffice+Spreadsheets+and+Java].
If you don't have any knowledge or experience, on the matter, please refrain from directing me to a google search. I assure you, I have already performed such a task.How would I know that.
But okay, let's say I know that. Let's say you bothered to point out that you've already done that. Further, let's say I do have knowledge of the subject at hand. Maybe I'm an expert. Maybe I wrote Star Office and an open source library (which wheel for some reason you must reinvent). You are assuming that I also have psychic powers, so that I can read your mind and know exactly what you've read so far and exactly what parts of your very broad and vague question said reading did not answer.
In short, you have received answers commensurate with your questions.

I am a CPA trying to convert depreciation schedules from ATX software PDF files into excel. Is that possible?
Hi Henry,
The ExportPDF online service allows you to convert PDF files to Excel format. I'm not familiar with ATX software, but in general, the quality of the conversion depends on how well the original PDFs are written.
If you decide to give ExportPDF a try, and it doesn't work out for you, you're welcome to cancel for a full refund within 30 days of subscribing.

Separate thread for input stream and output stream.
Hi Techies,
In a socket connection, can we run the input stream and output stream in separate threads. actually in my case, the input stream will be getting the input regularly and output stream will send data very rare. so if i impelment them in one class then unless there is data to send output stream will be blocked. i was thinking to impelment both the streams in separate threads. is it a good way? so how to implement it. your guidance will be of great help.
thanks in advance.JavaBreather wrote:

Iis it a good way? so how to implement it. your guidance will be of great help.Once you have a socket, create two threads, one which does the reading and one which does the writing.
You could use BlockingQueues to abstract access to these threads. i.e. the reading thread reads something from the socket and adds it to the BlockingQueue. The writing thread take()s something froma second BlockingQueue and writes it to the Socket. This way you add things to write or get thing to process by looking at the BlockingQueues. -
How to set input delay and output delay when source Synchronous
ClkIN is the board clock which is connected to the FPGA. Clkif is the generated clock from ClkIN. The Device's clk come from Clkif. So, how to set input delay and output delay in this scene(within my understand, this is Source Synchronous)?
The example in many document, the input delay and output delay setting all refer to board clock(within my understand, this is System Synchronous). In that scene, the input delay max = TDelay_max + Tco_max; input delay min = Tdelay_min + Tco_min; the output delay max = Tdelay_max + Tsu; output delay min = Tdelay_min - Th.
So, I want to know how to set input/output delay in the Source Synchronous.
In system synchronous, I set input/output delay such as:
create_clock -period 20.000 -name ClkIN -waveform {0.000 10.000} [get_ports ClkIN]
create_generated_clock -name Clkif -source [get_pins cfg_if/clk_tmp_reg/C] -divide_by 2 [get_pins cfg_if/clk_tmp_reg/Q]
create_clock -period 40.000 -name VIRTUAL_clkif //make virtual clock
set_input_delay -clock [get_clocks VIRTUAL_clkif] -min 0.530 [get_ports DIN]
set_input_delay -clock [get_clocks VIRTUAL_clkif] -max 7.700 [get_ports DIN]
set_output_delay -clock [get_clocks VIRTUAL_clkif] -min -0.030 [get_ports DOUT]
set_output_delay -clock [get_clocks VIRTUAL_clkif] -max 1.800 [get_ports DOUT]
*******************************************************************************************So, first. Architecturally, the clock that you forward to your external device should not come directly from the clock tree, but should be output via an ODDR with its D1 input tied to logic 1 and the D2 tied to logic 0. This guarantees minimal skew between the output data and the forwarded clock.
ODDR #(
.DDR_CLK_EDGE("OPPOSITE_EDGE"), // "OPPOSITE_EDGE" or "SAME_EDGE"
.INIT(1'b0), // Initial value of Q: 1'b0 or 1'b1
.SRTYPE("SYNC") // Set/Reset type: "SYNC" or "ASYNC"
) ODDR_inst (
.Q (Clkif_ff), // 1-bit DDR output
.C (ClkIN_BUFG), // 1-bit clock input
.CE (1'b1), // 1-bit clock enable input
.D1 (1'b1), // 1-bit data input (positive edge)
.D2 (1'b0), // 1-bit data input (negative edge)
.R (rst), // 1-bit reset
.S (1'b0) // 1-bit set
OBUF OBUF_inst (.I (Clkif_ff), .O (Clkif_out));
This generates an output clock that is the same frequency as your input clock. This is consistent with your drawing, but inconsistent with your constraints - is the forwarded clock a 50MHz clock or a 25MHz clock?
I will assume your ClkIN goes to a BUFG and generates ClkIN_BUFG. Your first constraint generates a 50MHz clock on the ClkIN port which will propagate through the BUFG to (among other places) this ODDR.
create_clock -period 20.000 -name ClkIN -waveform {0.000 10.000} [get_ports ClkIN]
Assuming your forwarded clock is supposed to be 50MHz, then your 2nd command is close to correct
create_generated_clock -name Clkif -source [get_pins cfg_if/ODDR_inst/C] -combinational [get_pins cfg_if/ODDR_inst/Q]
With this done, you have successfully described the forwarded clock from your design. This is the clock that goes to your device, and hence should be the clock which is used to specify your input and output constraints.
set_input_delay -clock [get_clocks Clkif] -min 0.530 [get_ports DIN]
set_input_delay -clock [get_clocks Clkif] -max 7.700 [get_ports DIN]
set_output_delay -clock [get_clocks Clkif] -min -0.030 [get_ports DOUT]
set_output_delay -clock [get_clocks Clkif] -max 1.800 [get_ports DOUT]
If you want to get fancier, you could try adding a set_clock_latency to the forwarded clock to account for the board propagation of the clock
set_clock_latency -source TDtrace2 [get_clocks Clkif]
(But I haven't experimented with clock latency on a generated clock and I don't know for a fact that it works).

Input Tax and Output Tax calculating wrong figures
Hi,
I have created Input Tax and Output Tax codes in SAP.
Input Tax- 3%
Output Tax- 4%
All the configuration is done as required. But when I am posting the Purchase and Sales Invoice, the tax amount is not calculating correctly.
For example:
Input Tax Calculation should be:
Vendor A/C.............. Cr 30000-
Expense A/C............ Dr 29100
Input Tax A/C............ Dr 900 (@3% on 30000)
Input Tax Calculation in SAP:
Vendor A/C.............. Cr 30000-
Expense A/C............ Dr 29126.21
Input Tax A/C............ Dr 873.79 (@3% on 30000)
The same is happening to Output Tax transactions.
Please advice.My understanding about the Input Tax and Output Tax was wrong. In the issue reported
Input Tax Calculation should be:
Vendor A/C.............. Cr 30000-
Expense A/C............ Dr 29100
Input Tax A/C............ Dr 900 (@3% on 30000)---my understanding was wrong.
Input Tax 3% should be charged on Expense amount, in this case Rs 30000. But because in the editing option calculate tax on net amount option was not selected, hence SAP was giving the below entry, which is correct as well.
Vendor A/C.............. Cr 30000-
Expense A/C............ Dr 29126.21
Input Tax A/C............ Dr 873.79 (@3% on 29126.21) which is correct.
Hence, the Vendor amount should be Expense + Input Tax= 30000 * 3%=900 + 30000 (expense) = 30900.
Correct Entry should be:
Vendor A/C...............Cr 30900
Expense A/C............Dr 30000
Input Tax A/C............Dr 900
Resolved. Pankaj has given the correct answer. -

Payroll Log - input,processing and output
ALL
i have a doubt here and i hope it would be cleared in this forum.
how does values comes in Input, Processing and output in payroll log.... for ex: sap provides detailed explanation in processing step.... where does this stored.... how it is appearing in payroll log.... plz. help to understand this.... Thank you all for your continuous contribution to this forumHi,
I think you are talking about the log that is getting after executing the Payroll.
If so, as an example, kindly goto Factoring and storage and double click on X023 (Gross input and storage).
Here, you can see the Input Table, Processing and Output Table.
If I am not wrong you are talking about the Processing that is displayed here.
If yes, Open the Schema through TCode PE01 and double click the Subschema for Period factoring and storage (INAL is the standard one. But if some 'Z' has been used instead of INAL double click that one). Here you can see X023 (Gross input and storage). Double click X023 and you can see Rule according to which the Processing is happening.
Thanks and Regards

How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?
Try connecting the iPad to the computer that you do not want to WiFi sync with and uncheck the WiFi sync option in iTunes. Then click on Apply. Reboot the iPad and see if that does the trick.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. -
C# Script to open and read an Excel spreadsheet with multiple worksheets
Can someone provide me the C# syntax and Edit Script to open an Excel spreadsheet with multiple worksheets and then using the data to create and output a .csv file? The multiple worksheets contain different data elements that I'll need to parse out and then
store as a .csv file that will then be read to pump data into our SQL Server Database.
Thanks for your review and am hopeful for a reply.
PSULionRPI think this code originally came from Joel, who comes here quite a bit. I'm not a C# expert, like Joe is, but I think this is pretty close to what you want.

Report output to excel spreadsheet
Hi,
I have a matrix report which will be run through oracle apps by the user. Now the user will open the output file in excel spreadsheet for further analysis.
I can not create an ascii file as it is a matrix type report. What could be the best solution ?
Thanks.Thank you so much Marwim. Your suggestion is very helpful. But I have some other Oracle reports which have only one .rdf file giving output in both pdf and Excel. This doubt might be silly. Almost same features were existing for the rdf what I am working now. For the remaining reports, it was given that DESFORMAT=SPREADSHEET , what this report lacks. I googled and found these links http://docs.oracle.com/html/B13895_01/orbr_paptoexcel.htm &
http://docs.oracle.com/html/B13895_01/orbr_paptoexcel.htm#CIHFDJAJ . But they are not intended for excel output. they generate only web layout in spreadsheet form. Could you please suggest any other ways to achieve this.
Thank you in advacne.

Help with our setup and output to Excel
OK, I work for the EPA Office of Research and Development (ORD) here in Cincinnati. We are working on this big project that is coming to an end. Basically, we have four different carts going. We have one ultra filtration cart (UF), one reservoir cart, one ion-exchange cart, and one RO cart. The UF, reservoir, and RO carts will all be hooked up to the computer via DASYlab.
Currently, we think that we have our DASYlab setup correctly. We want to graph everything over time and we want to export everything out to Excel so the data can be analysed later. I have been in contact with DASYlab help but this really isn't there job. I was wondering if someone could look at our DASYlab file (or give me idiot proof instuctions) into making sure that data is collected once every 2 seconds, the graphs are updated once every 2 seconds, and that the charts that will be output to Excel are updated once every 2 seconds. We are working on a P-M 1.8GHz notebook with a 100GB hard drive and 2GB of RAM so it can definately handle the flow of data.
No one in our project (or TTEB branch) has any experience with DASYlab. The last person to have this type of experience was working with Strawberry Tree back in the early 90's on a old 286 PC via DOS. It was actually the job of the contractors who built our equipment to get everything setup. However, they fell through as they didn't have any previous experience with DASYlab and they just didn't feal like reading through the 100's of pages of text. This assignment was handed over to me just last week and I think I have everything setup correctly. I just don't have to the time to fully read the manual.
I would appreciate any help. If someone can help then feal free to PM me and I can e-mail them the two necessary files.
ThanksWell I'm still pretty clueless about this, but for anyone who is looking at this and wondering, here's what I've gleaned:
1. After Effects, especially CS6, makes much more and better use of graphics cards than does Premiere Pro. I'm guessing that PP will, in future versions, make better use of them. For now, no need to spend more than a couple hundred bucks on one.
2. Update the software. PP and AE both performed substantially better after installing the .01 update from adobe. After you install the update, be sure to re-do the CUDA hack, if necessary.
3. As it stands, money for a PP system is best spent on a processor, as in the newest Intel (currently Ivy Bridge), and overclocked. This is where performance happens. I'd say on a 2012 system, 16 GB RAM should be considered a minimum for video editing, and 24 or 32 if you can afford it. More than that probably won't be utilized. Hard disks can affect performance, but I don't think it's a bottleneck unless you're doing something that requires VERY fast/large reads and writes (4k source?). Most people who have high-end editing stations also have a bunch of drives in RAID, but if you look at the performance chart, the SECOND highest scoring tester did not use RAID (though did use a presumably fast and large SSD).
Keep in mind that all of this has to do with RENDER speeds. I still don't know what the bottleneck is for PREVIEWS, but I'm just going to assume it's the same. -
Reg Input parmeters and Output parameters.
Hi frnds,
I would like to know about Input parameters and Ouput parametets.How they can be used in Smartforms. could please provide me some expamles if any.
Regards many,Defining a Form Interface
Use
You define a form interface to send data from your application to a form.
Integration
The form interface is a part of the Interface form object and is defined in the Form Builder. The form interface of a form is structured in the same way as the interface of a function module in the system. However, form interfaces do not support Changing parameters.
Prerequisites
● You have created an Interface form object.
● The application program provides the data that you want to insert in the form. Therefore, you already know the types of the corresponding variables.
The semantics of the valid parameter types match the semantics of a function module,
See also:
Getting Information about Interface Parameters
Overview of Function Modules (in ABAP Workbench: Tools)
Creating Function Modules (in ABAP Programming (BC-ABA))
Procedure
1. Open the required interface in the Repository Browser of the ABAP Workbench.
2. The Interface tab is displayed. Under Form Interface, double-click the Import node.
3. You see a screen for entering import parameters. This screen also shows the standard parameter /1BCDWB/DOCPARAMS. You cannot change this parameter.
You use this parameter in your application program, to specify the value for the language setting, for example. To display this structure in the ABAP Dictionary, double-click the SFPDOCPARAMS type.
4. XML schema-based interface
○ The standard parameter /1BCDWB/DOCXML with the type XSTRING is used for sending data from the application program.
ABAP-based or Smart-Forms-compatible interface
○ To insert a new line, choose Insert Line (). Enter the parameter names of the data you want to import. These names are valid for the whole form and do not have to match the variable names in the data collection program. All data types are valid. TYPE can be selected under Type Assignment.
5. When you double-click Export, you see the standard parameter /1BCDWB/FORMOUTPUT of the generated function module. You cannot change this parameter.
You use this parameter in your application program, to make the generated form available as a PDF for further processing, for example.
6. To display the exceptions used by the generated function module, double-click Exceptions.
7. Activate the interface.
At runtime, the application program must provide the parameters. If a parameter has been defined in the form, but is not defined when the application program is called, then the output of the form ends with the program crashing (hex dump).
However, it is also possible that the application program provides parameters that the form does not need. You do not need to mention these parameters in the form; they can also be specified in a different order from the code of the application program. This has the advantage that an application program can work with several different forms.
Migrated Smart Forms Interface or New Smart Forms-Compatible Interface
When you edit the interface of a migrated Smart Form or a new interface that is compatible with Smart Forms, the Tables option gives you extra parameters. When you set the Import, Export, and Exceptions parameters, the system also lets you use the standard parameters from the Smart Forms.
If you have a Smart Forms-compatible interface, you can use the existing application program of this Smart Form without making any modifications. (See also Switching Runtime in Migrating Smart Forms.)
Result
You have defined the form interface and you can use the specified parameter names in the form context.

Transaction CJI3 AND - batch job and output in excel format
We are trying to schedule a batch job and would like to have the output in an excel file. Is there a way to enhance CJI3 and FMEDDW to have the output in a excel file. I've looked at the Layout for creating the disvariant and I know you can have the output in excel format in the foreground, but I'm looking to put an excel file on the SAP DIRECTORY.
Has anyone done this?
Thank you.
LindaTalking about Enhancement Options, I believe you can achieve it using Enhancement Implementation. There must be one towards the end of the program just before the ALV is displayed. You can create an implementation of the implicit enhacement spot and output the file to a location maintained in some VAR (to keep the output location dynamic as we don't have it on the select screen).
My reply is not to the point but I hope you find a way using enhancement spots.
Should you need any help with enhancement implementation, following blog is good enough:
