Specification of the formal parameters for calling the lib function
Hello world
I want to call the function of library in CVI. When I run the project, it shows some unnecessary errors error message "formal parameter specification". (as pictured below)
I have no ideal with this error, because I call the function of library in VC6, it's OK no problem.
Could someone help me solve this problem?
Thank you!
My CVI file: http://d.99081.com/a710756/Test3.rar
the errors of the CVI:
The ICB is expected to underscore two traits before declspec (__declspec, not __declspec). VC allows __declspec or __declspec. You can either do a search/replace or add a definition like this in your file:
#define __declspec __declspec

Create parameters for the WriteData function
Hello
How would create parameters for the writedata function to populate the html code?
CODE:
Function GetCluster {}
and {{foreach ($Datacenter (Get-Data Center))
foreach ($Cluster in (Get-Cluster-location $Datacenter)) {}
New-Object PSObject-property @ {} TypeName

You specify when you call the writedata function, so I guess it's in the function Get-Cluster.
You can pass the object you create in the GetCluster function as a parameter.
Try something like this
Function GetCluster { & { foreach ($Datacenter in (Get-Datacenter)) { foreach ($Cluster in (Get-Cluster -Location $Datacenter)) { $clusObj = New-Object -TypeName PSObject -Property @{ vCenter = $Datacenter.Uid.Split("@")[1].Split(":")[0] Datacenter = $Datacenter.Name Cluster = $Cluster.Name HAEnabled = $Cluster.HAEnabled DrsEnabled = $Cluster.DrsEnabled DrsMode = $Cluster.DrsMode } writedata $clusObj } } } } # Function will compile the data passed from the GetCluster Function into HTML table format Function writedata { param ($object) $tableEntry = "
" Add-Content $fileName $tableEntry Write-Host $tableEntry}$($object.vCenter) " + " " + "$($object.Datacenter) " + "$($object.Cluster) " + "$($object.HAEnabled) " + "$($object.DrsEnabled) $($object.DrsMode) -

Help to find the specification of the specific motherboard for upgrades.
I searched for this motherboard specifications for spending a few hours, I recently have it this low-end PC medium-term and short-term use (until I can save up for a decent gaming platform in the future), but also I don't want to update some components to make it faster and more responsive , but I'm hard-pressed to find concrete information on this motherboard supports.
Office model is Acer Veritron M420, but I can't find the exact specifications of the motherboard, using the information system and CPU - Z that I could find:
Desktop model: Acer Veritron M420.
Motherboard: Acer RS780DV
Processor: Athlon II X 3 425 (Socket AM3 938)
RAM: Currently has 4 GB but supports up to 8 GB, already set the ram upgrade, pending order.
GPU: Radeon 3200 IGP. Is POWER supply 300W so my GPU choices are limited, but I'll think about it later, supposed to be that the motherboard supports the PCIE 16 X 2.0, but no information specific to this topic.
Here are the main elements that I intended to modernize a bit. Maybe even the CPU so I can find what max CPU model, it supports.

Is there a way to test for the first call of a function?
Hello
I created a function (using other functions I created) to generate a dynamic hierarchy tree menu based on parentID and itemID etc etc - I'm sure you are familiar with this concept. It works very well, and there is no problem.
However, I do all this build in a string, and then dumped on the page. Again, this works very well. However, because the function is called recursively, my class, the class = 'tree' repeat itself in each occurrence of the opening UL tag.
I want to only this class to be applied to the first UL, but because it is recursive, I don't know how to detect if the function is called for the first time or 5th time, etc.. I mean something like:
< cfif myFunction is called the first time >
Add the class
< cfelse >
do not add the class
< / cfif >
Please see my attached code. It is fully functional. Please don't worry that all the other functions do etc, they work very well, but I need a way or a variable to test against.
Any ideas?
Thank you very much

Call the javascript function using parameters cause run an immediate dependant
Hello.
I saw a strange behavior, if I try to use javascript parameters in the method af:clientListener property.
Using the syntax
and javascript<af:commandButton text="Init" id="cb1" partialSubmit="true"> <af:clientListener method="OnInitControl1" type="click"/> </af:commandButton>
the method oninitcontrol1 is called first with the click of the button.function OnInitControl1() { alert('OnInitControl1 called'); }
But with the syntax
and javascript<af:commandButton text="Init" id="cb1" partialSubmit="true"> <af:clientListener method="InitCtrl('Control1')" type="click"/> </af:commandButton>
the InitCtrl function is called immediately to the loading of the page.function InitCtrl(frameName) { alert('InitCtrl(' + frameName + ') called'); }
In both cases, the javascript file is inserted into the use of af: document
Is my "method" of the af property syntax: clientListener the problem?<af:resource type="javascript" source="/ScriptHelper.js"/>
Paul.Paul,
I don't know if you can call javascript with parameters in the way that you are currently using. However, have you tried using an af:clientAttribute and enhance the javascript?
Check the operating instructions by Frank on the related topic.

[8i] help with function with parameters (for the calculation of the work)
Let me start by saying, I've never written a function before, and I do not have access to create a feature in my database (that is, I can't test this feature). I am trying to achieve a function I can ask my IT Department to add for me. I hope that someone can take a look at what I wrote and tell me if this should work or not, and if it's the right way to go to solve my problem.
I'm creating a function to make a very simple calculation of work (add/subtract a number of days to a date in the calendar).
The database, I work with has a table with the schedule of work. Here is a sample table and sample data, representative of what is in my work table calendar:
The table includes since 01/01/1980 but 31/12/2015.CREATE TABLE caln ( clndr_dt DATE, shop_days NUMBER(5) CONSTRAINT caln_pk PRIMARY KEY (clndr_dt) ); INSERT INTO caln VALUES (To_Date('01/01/1980','mm/dd/yyyy'),0); INSERT INTO caln VALUES (To_Date('01/02/1980','mm/dd/yyyy'),1); INSERT INTO caln VALUES (To_Date('01/03/1980','mm/dd/yyyy'),2); INSERT INTO caln VALUES (To_Date('01/04/1980','mm/dd/yyyy'),3); INSERT INTO caln VALUES (To_Date('01/05/1980','mm/dd/yyyy'),3); INSERT INTO caln VALUES (To_Date('01/06/1980','mm/dd/yyyy'),3); INSERT INTO caln VALUES (To_Date('01/07/1980','mm/dd/yyyy'),4); INSERT INTO caln VALUES (To_Date('01/08/1980','mm/dd/yyyy'),5); INSERT INTO caln VALUES (To_Date('01/09/1980','mm/dd/yyyy'),6); INSERT INTO caln VALUES (To_Date('01/10/1980','mm/dd/yyyy'),7); INSERT INTO caln VALUES (To_Date('01/11/1980','mm/dd/yyyy'),8); INSERT INTO caln VALUES (To_Date('01/12/1980','mm/dd/yyyy'),8); INSERT INTO caln VALUES (To_Date('01/13/1980','mm/dd/yyyy'),8); INSERT INTO caln VALUES (To_Date('01/14/1980','mm/dd/yyyy'),9);
I have written (and validated) this parameter query that performs the calculation of my working day (mday):
Based on this request, I created the following function (and I have no idea if it works or if the syntax is right, etc..):SELECT cal.clndr_dt FROM CALN cal , ( SELECT cal.shop_days+:mdays AS new_shop_days FROM CALN cal WHERE cal.clndr_dt =:start_date ) a WHERE cal.shop_days = a.new_shop_days AND ROWNUM =1 ORDER BY cal.clndr_dt;
I'm also not sure how to do to have the function handle results that would return a date outside the range of dates that appear in the table (prior to 01/01/1980 or after until 31/12/2015 - or, another way to look at what was, before the caln.clndr_dt or the caln.clndr_dt MAX value MIN value).CREATE OR REPLACE FUNCTION add_mdays (start_date IN DATE, mdays IN NUMBER(5)) RETURN DATE IS new_date DATE; BEGIN SELECT cal.clndr_dt FROM CALN cal , ( SELECT cal.shop_days+mdays AS new_shop_days FROM CALN cal WHERE cal.clndr_dt =start_date ) a WHERE cal.shop_days = a.new_shop_days AND ROWNUM =1 ORDER BY cal.clndr_dt; RETURN new_date; END add_mdays; //edit 9:31 AM - noticed I left off this bit
My goal is to be able to use the function in a situation similar to the following:
First of all, here is a sample table and data:
And here's how I would use my function:CREATE TABLE orders ( ord_no NUMBER(5), plan_start_dt DATE, CONSTRAINT orders_pk PRIMARY KEY (ord_no) ); INSERT INTO orders VALUES (1,To_Date('01/08/1980','mm/dd/yyyy')); INSERT INTO orders VALUES (2,To_Date('01/09/1980','mm/dd/yyyy')); INSERT INTO orders VALUES (3,To_Date('01/10/1980','mm/dd/yyyy'));
Thus, the function would allow me to come back, for each command in my table of orders, the date is 3 days working (mdays) before the start of the plan of each order.SELECT orders.ord_no , orders.plan_start_dt , add_mdays(orders.plan_start_dt, -3) AS prep_date FROM orders
I go about it the right way? I have to create a function to do this, or is there a way for me to integrate my request (which makes my mday calculation) in the example query above (eliminating the need to create a function)?
Thank you very much in advance!

Fixed some typos in the last insert statements
Published by: user11033437 on February 2, 2010 09:31 (fixed some syntax in the function)Hello
Ah, referring to Oracle 8 and is not not able to test your own code makes me nostalgic for the good old days, when you have entered your cards and led to a window to the computer center and waited an hour for the work to be performed and then seen printing to find that you had made a typo.
If you write functions, you should really test yourself. Like all codes, functions forge be written small not: write a line or two (or sometimes just a part of what would later become a single line), test, make sure it is running properly and repeat.
Ideally, your employer must create a pattern of development in a development database that you can use.
You can legally download your own instance of Oracle Express Edition free; just be careful not to use features that are not available in the database where the code will be deployed.You need a function to get the desired results:
SELECT o.ord_no , o.plan_start_dt , MIN (e.clndr_dt) AS prep_date FROM orders o , caln l , caln e WHERE l.clndr_dt = o.plan_start_dt AND e.shop_days = l.shop_days - 3 GROUP BY o.ord_no , o.plan_start_dt ;
It would be more effective (and somewhat simpler) If you've added a column (let's call it work_day) identified whether each line represents a work_day or not.
For each value of shop_days, exactly 1 row will be considered as a working day.
Then, the query may be something like:SELECT o.ord_no , o.plan_start_dt , e.clndr_dt AS prep_date FROM orders o , caln l , caln e WHERE l.clndr_dt = o.plan_start_dt AND e.shop_days = l.shop_days - 3 AND e.work_day = 1 ;
You can use the analytic LAG function to populate the work_day column.
A function would certainly be useful, although perhaps slower.
The function you have posted has some errors:
an argument can be stated under NUMBER (5); Just NUMBER.
(b) when you SELECT in PL/SQL, as you do, you must SELECT a variable to store the results.
(c) ROWNUM is arbitrary (making it useless in this problem) unless you draw a neat subquery. I don't think you can use ORDER BY in subqueries in Oracle 8. Use the ROW_NUMBER analytic function.
(d) the service must end with an END statement.Given your current caln table, here's how I would write the function:
CREATE OR REPLACE FUNCTION add_mdays ( start_date IN DATE DEFAULT SYSDATE, mdays IN NUMBER DEFAULT 1 ) RETURN DATE DETERMINISTIC IS -- add_mdays returns the DATE that is mdays working days -- after start_date. (If mdays < 0, the DATE returned -- will be before start_date). -- Work days do not include Saturdays, Sundays or holidays -- as indicated in the caln table. new_date DATE; -- to be returned BEGIN SELECT MIN (t.clndr_dt) INTO new_date FROM caln f -- f stands for "from" , caln t -- t stands for "to" WHERE f.clndr_dt = TRUNC (start_date) AND t.shop_days = f.shop_days + TRUNC (mdays) ; RETURN new_date; END add_mdays; / SHOW ERRORS
Production code forge be robust (which includes "fool-proofing").
Try to anticipate what people errors might appeal to your function and correct for them where possible.
For example, if it only makes sense for start_date at midnight, mdays to be an integer, use TRUNC in the function where soembody passes a good value.
Allow default arguments.
Comment of your function. Put all comments within the service (i.e. after CREATION and before the END) so that they will remain in the data dictionary.
If, given the same arguments, the function always returns the same value, mark it as DETERMINISTIC, for efficiency. This means that the system will remember the values transmitted rather than to call the function whenever it is said to.I wish I could score questions such as 'Correct' or 'useful '; you get 10 points for sure.
You posted CREATE TABLE and INSERT statements (without even be begged).
You gave a clear description of the problem, including the expected results.
The code is well formatted and easy to read.
All around, one of the more thoughtful and well written questions I've seen.
Play well! Keep up the good work!Published by: Frank Kulash, February 2, 2010 13:10

Call the DLL function with a pointer to a complex structure

{
ULONG i;If (DFR > = DevNum)
Return PCICORE_DEVICE_NO_FOUND;If (DevTable [JC]. DevHandle is NOTHING)
Return PCICORE_DEVICE_NO_INITIALIZE;if(pdevinfo == null)
Return PCICORE_INVALID_PARAMETER;pdevinfo-> dwBarNum = DevTable [JC]. DevInfo.dwBarNum;
< pdevinfo-="">dwBarNum; i ++)
{
pdevinfo-> .dwFlag BarInfo [i] =
DevTable [JC]. DevInfo.BarInfo [i] .dwFlag;
pdevinfo-> .dwSize BarInfo [i] =
DevTable [JC]. DevInfo.BarInfo [i] .dwSize;
}Return PCICORE_SUCCESS;
}As an attachment, there is the Info.vi device Get trying to access this feature. The code crashes when the function is called.
I have probably not pass parameters of data properly to COLD LAKE.
Thank you for your lights.
An array of fixed size in C is equivalent to a cluster of LabVIEW that contains the same number of identical items, replace the table with a cluster. In addition, structs are always passed by reference and the C function expects a pointer to a structure, you don't need to unbundle. Skip the cluster to function as a single parameter. Try the attached revised version of your VI.
