Solve equation with one unknown parameter (x)

I am working on a Windows Phone program that calculates taxes due. One of the calculations is a formula/equation with an unknown 'x'. I have searched a lot on solving equations with vb but this really exceeds my - admittedly small - math knob. Perhaps you
can help me out.
The equation to solve is (for example):
((25000 + x) * 0.06) + x = 16500
The only unknown variable is x. Does someone know the proper code to solve this equation?

Are you looking to code some super-intelligent maths equation solver that can solve any type of equation (if so - good luck!)? Or are the equations you want to solve all of the same type?
The example you gave is of the form (A + x) * B + x = C. You can rearrange that to (1 + B) * x + A * B = C and from there to x = (C - A * B) / (1 + B).
If all your equations are in that form, you just need to identify the value of A, B and C and use the last formula I gave to calculate x.
I wasn't going to do that for him.
Let's see here, he's building a program for tax calculation and he can't do 8th grade algebra??
Still lost in code, just at a little higher level.

Equations With Two Unknowns Algorithms

Hi Everybody,
I need to write a processing function.
Let me briefly describe the processing steps I need to do.
PARAMETERS : sum_kdv TYPE i,    "total value-added tax.
                           sum_tut TYPE i.      "total amount
We will turn to process these parameters.
Process ;
x    +    y           = sum_tut.
0,01x + 0,08y   = sum_kdv.
To find the values of x and y will do mathematical operations.
    -0,01( x + y ) = -0,01(sum_tut) .
     0,01x + 0,08y   = sum_kdv.
+------------------------------------------
We will find the value of x i y destroying.
How can we do this.
Best Regards Rasim.

Is it math calculation??
x= sum_tut - ( 100- sum_kdv ) / 7
y= ( 100- sum_kdv ) / 7
Am I right?

How to handle multiple reports with single hyperlink parameter

Please suggest in my drill down report
i have two reports linked with one hyperlink
parameter, how to handle this?
please suggest for popup window with sample solution.
for example
report A--->B--->Chosse Report c or D
based on parameter hyperlink at report B.
Thanks in advance
Raj

Yes U R correct, that
I'm using srw.set_hyperlink in plsql format trigger
to open other reports , now the problem is
how to carry over the hyperlink parameter to popup window
and allow user to choose any reports based on the
parameter value.
for example
report A (Sales person summmary report)
|
| (choose sales person drilled to orders report B)
|
B (report has the hyperlink on order no)
|
|
C,D,E (many reports based on order no
customer,order details,pending items
to be shipped)
Now how to handle the situation from b to c,d,e
I suggest use hyperlink at B to open popup to show
reports C,D,E with the order no has parameter.
please suggest for javascript to open popup window
for reports c,d,e.
Thanks

Error when linking report to stored procedure defined with one input parm

Error when linking report to stored procedure defined with one input parameter
The report will work ok, when the parameter is removed from the stpred procedure
An unhandled win32 exception occurred in crw32.exe[4480]
Stored Proc (sql server 2005)

End;

This is an example of a stored procedure that is trying to be linked to a new report as the only datasource.
If I remove the parameter I can create a report, however this will return all of the results of thw query to the report, rather than the desired results. If I add the parameter on the Crystal Report, the stored procedure then has to return all of the results to Crystal and then perform the filtering of records. By using a parameter in the stored procedure, you should be able to do all of the filtering as part of the query on the databse server, making this more efficient.

Solving nonlinear equation with VI

Hi,
I want to use LabView to solve a nonlinear equation. I read forums and figured out that I can use Nonlinear System Solver. vi and I noticed there are two options to write the equation: 1) F(X) is formula and 2) F(X) is VI. I could use the first option and write the equation with that but I did not understand how to use a sub-Vi to provide the equation. Would any one please tell me how to do that?
Thank you

Soran,
Read the detailed help for the solver VI.
The VI usually executes much faster than the formula parser/evaluator. Since solvers (and curve fitters, which have the same options) may need to evaluate the function many times while solving, that time can become significant.
In the help is a link to a template for the VI you need. You must use the exact connector pane and reference type. While you can create your own VI, it is much easier to use the template. On the block diagram create the code to generate your equation values in the configuration required by the solver. Be careful to put the parameters in the correcto order.

When i updated itunes I lost all my music, I was able to retrieve it from my previous version, but now a artists have all of their songs list under one unknown cd. How can I seperate these cds with the correct songs included?

When I updated itunes I lost all of my music, I was able to retrieve it from a previous itunes library, but now some artists have all of their songs listed under one "unknown album." Is there a way to separate these songs back into the correct albums? Also, is there a way to make songs that have a featured guest just show up with the rest of the album instead of making a whole new spot for it? Thanks!

" When I did this, my library showed all the music I have "purchased" from itunes but did not have the music that I downloaded a long time ago through itunes from my old CDs."
Correct.
" How can I get that music to show up in my library now on my new computer? "
Copy it from your old computer or your backup copy of your old computer.
The sync is one way - computer to ipod.

Hello,
How about this as an alternative:
Use a functional global which has 3 cases:
1. open config file - it opens the config file and reads the contents into a string (which is the functional global data), and you only do this one time at the beginning of the program.
2. edit config data - it edits the string, which are really the contents of the file, but doesn't worry about writing to the file. you could even get fancy here, and allow an array of tags and an array of values as input, and it would go update/edit all the tags to have the corresponding values.
3. close config file - it writes the current string data (the functional global data) to the file and closes it.
Using the functions in the string palette, I think you'll find most of the code for that module/functional global will be easy to write.
I hope this helps!

Dictionary has trouble with one of its fonts... How to solve?

Hi everyone,
My problem is the following: the OS X Dictionary app has severe trouble displaying one of the fonts it uses, I assume it should be Baskerville Italic (Bold Italic gets displayed correctly). See the following screenshot:
I have pretty much tried everything: resetting system fonts via Font Book, manually de- and reactivating the fonts Dictionary uses (Baskerville, Helvetica Neue, and Hiragino Mincho Pro W3; they're all active now) and checking whether I have other fonts that OS X could possibly confuse with one of the system fonts (I have a large font library with many duplicates from art school). Nothing helped.
Anybody had a similar problem and found a solution for this?
On a related, but less important note: when I reset all system fonts with Font Book (which should throw all fonts that are not included in OSX in a separate folder and deactivate them, as far as I understood it), nothing happened, except that he told me all my system fonts are fine. Could it be that installing new versions of OSX over older ones confuses the system about which are system fonts and which aren't?
And: I cannot find Baskerville in the system font folder at /System/Library/Fonts. Isn't it supposed to be there if Dictionary uses it?
Thanks for any help!

mentalmenthol wrote:
In addition to those I had separate font files called e.g. "Cyrillic A Upright", "Greek Inclined" etc. that would apparently only include the respective character sets (counting around 200-250 characters each). These are the ones I deactivated entirely
Thanks for the explanation! Those separate font files are what I meant by "junk", but that is not really a good term in this case, they are just using a non-standard encoding which is potentially incompatible with the Unicode standard used by OS X. Lion's expanded Baskerville is the Unicode replacement for them.
It is quite common for OS X to get confused by fonts like that which map symbols to Latin instead of their correct Unicode assignments. Helvetica Fractions and Times Phonetic have caused similar problems for many users in the past.

How to run the same SSRS report multiple times, each time with a different parameter value?

Hi,
I have an SSRS report that produces a list of invoices for a single supplier (so supplier is a parameter specified at runtime). The report is based on a stored procedure in SQL. I would like to make things easier and instead of going through all suppliers
one by one, I want to have a single action, which produces separate reports, per supplier, for all suppliers that have an outstanding invoice (so not all suppliers on the system as a whole but all suppliers that are within the result set of the stored procedure).
I assume this would mean first executing the stored procedure to find all suppliers that have invoices at the time. And then running the report multiple times, once for each supplier, where the supplier value is used as the parameter every time. ideally
this would open separate webpages with a single report per page. (I am creating a button in another software, which is simply launching iexplore.exe and passing a
fixed SSRS report URL).
What would be required? I have SQL 2012 and I am building this in Report Builder 3.0.
Thank you!
Dimitar
P.S. What about still running ONE report, but every supplier starting on a new page? Is that more realistic? So supplier will not be a parameter any more, but just something that creates a new page on the report?

What
about still running ONE report, but every supplier starting on a new page? Is that more realistic? So supplier will not be a parameter any more, but just something that creates a new page on the report?
Yes thats a much better option. Its very easy to generate such a report in SSRS. You dont need a parameter
in that case but just needs to add Supplier as a grouping field in the tablix. Then add other columns and groups if required. Select option set page break after each instance of the group for first grouping (ie based on supplier field). Then report will render
with one page per supplier. On exporting to excel also each supplier data goes to a different tab
Here's a similar requirement I did for one of my projects

[SOLVED]Issue with Postfix sending to external mail addresses

I'm having a very silly issue with Postfix. I followed the wiki article at [link]https://wiki.archlinux.org/index.php/Postfix[/link], and everything seems to work properly, however I cannot send to emails outside of my domain.
I get the error:

# SENDING MAIL
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites. If you run a domain with multiple

# REJECTING MAIL FOR UNKNOWN LOCAL USERS
# The local_recipient_maps parameter specifies optional lookup tables
# with all names or addresses of users that are local with respect

# If this parameter is defined, then the SMTP server will reject
# mail for unknown local users. This parameter is defined by default.
# To turn off local recipient checking in the SMTP server, specify
# local_recipient_maps = (i.e. empty).
# The default setting assumes that you use the default Postfix local
# delivery agent for local delivery. You need to update the
# local_recipient_maps setting if:
# - You define $mydestination domain recipients in files other than
# /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
# For example, you define $mydestination domain recipients in
# the $virtual_mailbox_maps files.
# - You redefine the local delivery agent in master.cf.
# - You redefine the "local_transport" setting in main.cf.
# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
# feature of the Postfix local delivery agent (see local(8)).
# Details are described in the LOCAL_RECIPIENT_README file.
# Beware: if the Postfix SMTP server runs chrooted, you probably have
# to access the passwd file via the proxymap service, in order to
# overcome chroot restrictions. The alternative, having a copy of
# the system passwd file in the chroot jail is just not practical.
# The right-hand side of the lookup tables is conveniently ignored.
# In the left-hand side, specify a bare username, an @domain.tld

# TRUST AND RELAY CONTROL
# The mynetworks parameter specifies the list of "trusted" SMTP
# clients that have more privileges than "strangers".
# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix. See the smtpd_recipient_restrictions parameter
# in postconf(5).
# You can specify the list of "trusted" network addresses by hand
# or you can let Postfix do it for you (which is the default).
# By default (mynetworks_style = subnet), Postfix "trusts" SMTP
# clients in the same IP subnetworks as the local machine.
# On Linux, this does works correctly only with interfaces specified
# with the "ifconfig" command.
# Specify "mynetworks_style = class" when Postfix should "trust" SMTP
# clients in the same IP class A/B/C networks as the local machine.
# Don't do this with a dialup site - it would cause Postfix to "trust"
# your entire provider's network. Instead, specify an explicit
# mynetworks list by hand, as described below.
# Specify "mynetworks_style = host" when Postfix should "trust"
# only the local machine.
#mynetworks_style = class
#mynetworks_style = subnet

# mask specifies the number of bits in the network part of a host
# address.
# You can also specify the absolute pathname of a pattern file instead

# By default, Postfix relays mail
# - from "trusted" clients (IP address matches $mynetworks) to any destination,
# - from "untrusted" clients to destinations that match $relay_domains or
# subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces or $proxy_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_alias_domains,

# internal DNS uses no MX records, specify the name of the intranet

# A Postfix process will pause for $in_flow_delay seconds before
# accepting a new message, when the message arrival rate exceeds the
# message delivery rate. With the default 100 SMTP server process

# details.
# If you change the alias database, run "postalias /etc/aliases" (or

# Exception: delivery for root is done as $default_user.
# Other environment variables of interest: USER (recipient username),
# EXTENSION (address extension), DOMAIN (domain part of address),
# and LOCAL (the address localpart).
# Unlike other Postfix configuration parameters, the mailbox_command
# parameter is not subjected to $parameter substitutions. This is to

Your main.cf seems redundant.
For example:
if you specify:
virtual_alias_maps = hash:/etc/postfix/virtual_alias, mysql:/etc/postfix/mysql_virtual_forwards.cf
you don't need this:
alias_maps = hash:/etc/postfix/aliases
and i think you have a lot of more options you don't need.
This is my main.cf on my vps and everything works great (sending and receiving emails from/to most common mail server: gmail, hotmail etc etc)
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
# appending .domain is the MUA's job.

virtual_transport = dovecot
dovecot_destination_recipient_limit = 1
it is very simple (no dkim, no forced tls, no mailbox limits and so on) and it can be improved but it works..
as I suggested you just try spending some hour wiping postfix installation and giving a look to this guide

How to call a form with dabble clicking on a record with one time where

Hi All,
How to call a form with dabble clicking on a record with one time where clause. I mean when i dabble click on the current record i want to call another form with details of the
record with onetime where clause. Can anyone help me in this regard.
Now i am calling a form with parameter with onetime where but this should avoid.
Thanks in advance
Arif

Hello,
I mistakenly mark it as solved. There is a problem remain. when i placed the code below it do not execute with the where condition. I mean the condition to execute is not work.
All records executes. Please correct my code--
Here the WHEN-BUTTON-PRESSED-trigger on the Edit-Button:
:GLOBAL.MODE:='EDIT';
:GLOBAL.REQ_ID:=:PROBLEM_REQUEST.REQ_ID;
CALL_FORM('REQUEST_ID_PARAM',NO_HIDE,DO_REPLACE,NO_QUERY_ONLY);And also, WHEN-NEW-FORM-INSTANCE-trigger of REQUEST_ID_PARAM:
DEFAULT_VALUE(NULL, 'GLOBAL.MODE');
DEFAULT_VALUE(NULL, 'GLOBAL.REQ_ID');
IF :GLOBAL.MODE='EDIT' THEN
GO_BLOCK('PROBLEM_REQUEST');
EXECUTE_QUERY;
SET_BLOCK_PROPERTY('PROBLEM_REQUEST', INSERT_ALLOWED, PROPERTY_FALSE);
END IF;Arif

Equation with dynamic variable

Is it possible to use one equation with 2 or more variables and make one of these variable as an output without changing the equation?
Take the equation below example:
R=x/(0.28706/0.46153+x)*(101.325/P)
As usual, by inserting the values of x and P, then value of R will be answered.
But if only the value of R and x can be inserted, how can the value of P to be answered without altering the equation.
The equation is being used multiple time in the same VI. One is for generating one part of a graph (Mollier Diagram) and the others are to be used to find the value at the intersection.
I hope my question is understandable.
Thank you in advance

Solved!
Go to Solution.

R = (x/(a+x)*(b/P) ... thx, this really will be helping me to make this Eq more understandable
Formula Node:
It seem that when i entered an equation(Eq), only the left side of the Eq can only be one variable thus producing a single output.
Case Structure(or SELECT function):
It changes the formula to a new form for every output. Let say i want make x an output. That means i need to create a new Eq : x=(P*R/b-1)*a, which i want to avoid if posible .
.... Does this means that a new Eq must be created/converted for each output.
Newton Raphson zero finder vi: (base on this N-R Example)
I have tried using this VI by making my Eq equivalent to zero and using SELECT function depending on situation. Somehow i think it will work, but the VI seem too bulky for one simple formula (with 2 variable and 1 output), which i want to avoid since many more formula will be used.
I ll be glad to see more suggestions.

Solve equation with one unknown parameter (x)
