Minimum coverage value should be greater than zero (host machine)

Hi,
I am working on an host machine (windows 7, LabVIEW RTE 2010, VAS 2010 (evaluate version)) with an application created on another machine (Windows XP, LabVIEW 2010, Vision Development Module 2011).
This application is supposed to aquire an image by a USB camera.
When I run this application on the development machine, it works fine.
On the host machine, I can see my camera with MAX and do whatever I want to do with MAX.
When I run the application on the host machine, the application starts but when it is supposed to use the camera I got thes error (see attached file).
I tried to uninstall and reinstall all Lab'VIEW"s softwares but I still have this issue...
Any idea will be appreciated!
Thank you!

Greetings, nicocmd;
First and foremost, it is excellent that you are now up and running!
In what concerns your question, do you mean to continuously see the image displayed in a live feed and only save it when the user clicks a button or some such? What do you mean with only using IMAQdx VIs? Would it refer to not using the IMAQ For USB VIs?
If you would desire to take in images from the camera and display them in a live feed, you could simply set up an IMAQdx acquisition and either use the Grab or the GetImage VIs and have a case structure in which you decide whether or not to save the image that was just displayed (or the next one that will be taken).
I did a tad of research and came across the following forum post; in it, another user posted a VI that might be of service to you, for it saves images into a tiff file.
http://forums.ni.com/t5/LabVIEW/IMAQdx-grab-and-save-images-i-e-PNG-TIFF-etc-not-AVIs/td-p/1044201
Finally, if you would mean using only IMAQdx VIs and not IMAQ, then I do not believe it is possible simply because the vision utilities (Such as creating the image memory location) will be part of the IMAQ palette.

IMAQ Vision: (Hex 0xBFF60488) Minimum coverage value should be greater than zero.

Having some trouble with extended acquisition of a Mightex USB camera using LabVIEW 8.5. LabVIEW is able to acquire images from this camera using IMAQ USB, a snap every ~30 seconds. After about 1100 snaps LabVIEW errors out: IMAQ Vision: (Hex 0xBFF60488) Minimum coverage value should be greater than zero.
Any help would be greatly appreciated!

Minimum in range greater than zero

I'm trying to find the minimum number in a row but I want to find a number greater than zero as the minimum not the zeros .

Badunit's remark that "Your numbers must all be >=0" led me to check all three suggestions against this possiblity. Here are the results for two data sets, one containing text, blank and negative values, the second containing only positve numbers, zero, and a blank cell.
As you can see, my procedure includes both positive and negative values, and eliminates only the zeros from contention. If your data will include negative values, and you do NOT wish to include them, they may be easily stripped from the data when it is transfered the the Aux column, in the same manner as the zeroes have been.
Stripping all values less than or equal to zero requies a minor edit of the formula in the AUX column:
Original: =IF(B=0,"",B)
Revised: =IF(B<=0,"",B)
Jerry's formula requires that it be placed into a Footer row (or a Header row) IF it is to be placed on the Data table and to use the table name ("Data") as the first argument for INDEX. INDEX ignores Header and Footer rows in arguments specifying a whole column (or a whole table).
As can be seen in column B, this formula will be thrown off (as BU has warned) by the inclusion of negative values. A revision similar to the one shown in my formula above will remove the requirement to not include negative values:
Original: =SMALL(B,COUNTIF(B,0)+1)
Revised: =SMALL(B,COUNTIF(B,"<=0")+1)
As revised, the formula will return the smallest positive value in the data list.
Badunit's formula will also show a warning triangle if there is an empty cell or a cell containing text in the data list. Annoying, but it does not affect the results. The warning is that "The formula refers to cells without numbers,"

How to zero the values that are greater than 0 at time 0?

Hello, New user,
I would like to know how to zero values that are greater than 0 at time 0. I am totalizing gas flow and understand how not to add the negative numbers but am unsure about the positive numbers at 0 flow. I hope I have explained this good enough.
Thank you,
Lisa

I don't understand why the value which should be 0 is actually greater than 0.
How do you determine that the value should be 0, such as no flow, even if the value is greater than 0?
Ryan Shi
Hello Ryan,
The system itself may have an offset of 0.1 V which in the program is related to flow. I do not wish to add this .1 as flow. I want to beable to reset the values to 0 and then when there is flow, to add the flow. If you purchase a program from some vendors you can zero the channel, that is my goal. I want this to be automatic when a switch is pressed. Such as: for 20 seconds, average channel, and use that value as 0 flow then add flow?? I was told averaging may work??
Thank you again,
Lisa Williamson

Bar charts- can bar start at a point greater than zero?

I would like to create a bar chart where data for each category covers a range. Is there a way in Numbers to start a bar chart at a value greater than zero and extend for a defined amount? For example, start the bar at 70 and stop at 200?
I can do this in Excel, but haven't found a way to do it in Numbers yet. Any ideas?

Yes. Select the chart by clicking anywhere on it. Then click on the Inspector icon in the Tool Bar. In the Inspector pane which opens, click on the Chart symbol in the row of icons across the top of the pane; the Inspector pane changes to show Chart properties. Look down the pane until you see Value Axis Format which shows 3 white boxes. In the first box, type the value you want your chart Value axis (the chart vertical axis) to start at. In the second box, type the value you want for its upper limit, and in the third box, type the number of steps you want displayed on your axis. E.g. Minimum = 200, Maximum = 800, Steps = 3 will give a chart axis which starts at 200 (a supressed zero), ends at 800, and shows 3 values (400, 600 & 800) in addition to the base value of 200.
Hope this helps,
Ian Mathieson.

WS Error - Planned Qty should be greater than Completed + Rejected Qty

Hi All,
We've tried to close a Production Order using the ProductionOrdersService Web Service. We're doing this by setting the Production Order Status flag to closed (boposClosed). The call also requires us to re-set the due date so we do that to the same value.
When we perform the call we receive the following exception:
"Planned Qty should be greater than Completed + Rejected Qty [OWOR.PlannedQty]"
It's interesting to note that we've tried to close the production order with different items and everything seems to point towards an issue with the items, however, we're not really sure what is triggering the error. We're also not sure what the error really implies as the Planned Qty is greater than the Completed + the Rejected Qty on the database.
We're working with SAP 8.8.1.
The code is as follows:
        // Get the current session ID first
        // Create message header object with value..
        SAPProductionOrdersService::MsgHeader^ localMsgHeader = gcnew SAPProductionOrdersService::MsgHeader();
        localMsgHeader->SessionID = sessionId;
        localMsgHeader->ServiceName = SAPProductionOrdersService::MsgHeaderServiceName::ProductionOrdersService;
        localMsgHeader->ServiceNameSpecified = true;
        SAPProductionOrdersService::ProductionOrdersService ^iprodWs = gcnew SAPProductionOrdersService::ProductionOrdersService();
        iprodWs->MsgHeaderValue = localMsgHeader;
        // Set the item params object
        SAPProductionOrdersService::ProductionOrderParams^ localProductionOrderParams = gcnew SAPProductionOrdersService::ProductionOrderParams();
        localProductionOrderParams->AbsoluteEntry = ProductionOrderNum;
        localProductionOrderParams->AbsoluteEntrySpecified = true;
        // Perform the Item fetch with that information
        SAPProductionOrdersService::ProductionOrder^ localProductionOrder = iprodWs->GetByParams(localProductionOrderParams);
        // Construct a new Production Order Data structure
        SAPProductionOrdersService::ProductionOrder^ newProd = gcnew SAPProductionOrdersService::ProductionOrder();
        // Absolute Entry
        newProd->AbsoluteEntry = ProductionOrderNum;
        newProd->AbsoluteEntrySpecified = true;
        // Production Order Status
        newProd->ProductionOrderStatus = SAPProductionOrdersService::ProductionOrderProductionOrderStatus::boposClosed;
        newProd->ProductionOrderStatusSpecified = true;
        newProd->DueDate = localProductionOrder->DueDate;//     {6/9/2011 0:0:0 System.DateTime}     System::DateTime
        newProd->DueDateSpecified     = localProductionOrder->DueDateSpecified;//     bool
        // Setting lines array back
        newProd->ProductionOrderLines = localProductionOrder->ProductionOrderLines;
        // Item Code
        newProd->ItemNo = ItemNum;
        // Perform the Update of the Production Order with that information
        iprodWs->Update(newProd);
        // Since there is no return type telling us of the recent update, unless we get an exception, assume it worked
        String^ recMsg = "Close Production Order Attempt Successful. Parameters are: \r\n" +
                         "Production Order Num: " + ProductionOrderNum;
        Log::LogInformation(recMsg);
        retVal = true;
Hector

Dear Gordon,
Yes, I have checked the data in the database. I've checked tables OWOR fields PlannedQty, CompletedQty and RjctQty and everything seems to be in order. I also checked table WOR1 for the production order lines. There are two lines, one Labor and one Raw Material (regular item). I've checked BaseQty, PlannedQty and IssuedQty but everything seems in order there as well.
Do you know if there is a way to find out what internal piece of code throws that exception message?

Goods receipt date should be greater than the P.O. date

Hi
Is there any option to control the Goods receipt date should not be lesser than the P.O.Date??
Eg: P.O. is raised in 10.1.9, User should not do the GRN before 10.1.9. In which way we can control this???
Regards
Ravi

Dear,
You have to include User exit in MIGOwhich will trhrow an error at the time when Goods receipt date is greater than the P.O. date.

Why domain functional level should be greater than or equal to forest FL?

We know that domain functional level must be greater than or equal to forest functional level. Why is that so?
My perspective is if we set FFL to windows server 2008 r2 and DFL to windows 2003, active directory recycle bin won't be available to the domain whose FL is windows 2003. Is that right?

My perspective is if we set FFL to windows server 2008 r2 and DFL to windows 2003, active directory recycle bin won't be available to the domain whose FL is windows 2003. Is that right?
Greetings!
Active Directory Recycle Bin needs to be implemented in a forest with 2008 R2 forest functional level. Because it was added in 2008 R2 operating system. In order to have a 2008 R2 forest functional level you need to raise all the child domains DFL's first.

Finding the minimum number greater than zero in an array

Hi All,
I have an Array (Attached). I need to find the minimum number that is NOT zero.
Using the Array Max & Min returns 0 as the min. What I want is the next minimum number.
Thank you.

Do you also need the position of the found element? What if several numbers have the same minimum value?
If you just want the value of the smallest nonzero element, here's what I would do. All you neet to do is retain is a single number.
This assumes that your zeroes are really zero. With DBL you never know.

[10g] Way to find least value greater than a value?

I have a simple (I think) question ...
Part 1:
Is there a way to determine the least value, among a set of values, that is greater than 0?
A couple of examples:
Set of values:
{0,1,2,3}
Return value:
1
Set of values:
{0,5,10,20,100}
Return value:
5
Set of values:
{1,4,9,11}
Return value:
1Part 2:
Same thing, but greater than some given value, not necessary 0.
Set of values:
{0,1,2,3}
Parameter value:
2
Return value:
3
Set of values:
{0,5,10,20,100}
Parameter value:
2
Return value:
5
Set of values:
{1,4,9,11}
Parameter value:
2
Return value:
4In particular, I'm looking for an efficient way of doing this. I believe I can do it with a set of CASE statements, but it gets really complex the more values you are comparing.
My first thought was to use the LEAST function, but that doesn't allow me a way to use a parameter.
Any suggestions?

-- this section has been edited
And that's basically where I was heading. I was hoping there was a less complex way to do it... somehow replacing any zeros with an impossibly large number, without using case statements (something equivalent to the NVL function, but to replace any value with another), so that they'd never be less than anything, and then I could just use the LEAST function. The only way I can think of to do that though, would be to convert the numbers to strings, use REPLACE, and then convert them back to numbers, which doesn't seem less complex than the CASE statements, and most likely is worse performance-wise.
For example:
SELECT     ord_nbr
,     seq_nbr
,     time_spent /
     CASE     WHEN     comp_qty     <= plan_qty
          AND     comp_qty     <> 0
          THEN     comp_qty
          WHEN     comp_qty     > plan_qty
          THEN     LEAST     ( TO_NUMBER(REPLACE(TO_CHAR(ord_qty-scrap_qty),'0','999999999'))
                    , TO_NUMBER(REPLACE(TO_CHAR(plan_qty),'0','999999999'))
                    , TO_NUMBER(REPLACE(TO_CHAR(comp_qty),'0','999999999'))
          ELSE 1
     END     AS unit_time
FROM     ord_detail
;-- end of section edited (I posted before I had fully gone through the solution provided)
I checked the data, and though, theoretically all values could be zero, there are no instances where that happens. I think that, in the case all values were 0, I'd just want to use 1 instead.
Side note on the "big" problem behind this question....
My ultimate problem, (and if I end up needing help with that, I'll start a new post for it) is that the quantity data in our system has a fair amount of junk in it...values that can't be true. With this solution, I would assume that in any case where the quantity complete at a given step of a process is less than or equal to the quantity planned to be complete at that step, the value is good, which is not necessarily a correct assumption. Then, only in cases where something can't be true, like when quantity complete > the quantity planned, are when I would intervene with this solution to make a "best guess" at the correct value. There a few things related to this that I have to determine before I can figure out my next step.
We have another database (so we can keep things straight, I'll call the database I've been querying up til now DB1, and this other one, DB2) that has much more reliable quantity data and step data (sometimes it has steps that aren't in DB1) but its structure is complex, I'm rather unfamiliar with it, and it does not have time spent data. Additionally, some products have all their information in DB1, and none in DB2.
So my options are to:
1) ...try to learn the structure of the other database, find the data I need, and query both databases together, using this thread's solution to resolve any questionable data that does not exist in both systems, and skipping any steps that occur in DB2, but not DB1 (since they won't have any time data, which is ultimately what I'm after)
2) ...try to come up with a method to pre-"scrub" my data in DB1, based on some logical assumptions and looking at all steps in an order, so that I can then just query the scrubbed data...
3) ...use the solution from this thread, and assume that the bad data isn't enough to significantly impact my calculations...
What I wouldn't give for a single system with all good data!

Value should start with zero

Hi experts
I have a target field whose values should generate starting from zero
I am using gen_row_num but it starts from 1
Any Suggestions Please
Thanks
Madhu

Hello
So, you need the value to be one less than the one that is generated? Simple maths suggests subtracting 1 from the generated value will give you what you require.

MIRO posted greater than PO values and quantities.

Dear friends !
We are posting MIRO agains't PO but without MIGO , only MIRO directly.
We must enter the quantity and net value at MIRO line item and the value at Amount with Taxes at tab Basic Data.
But if PO was created with a qty 100 Hours for example and the price is 10,00 per hour , the total amout is 1000,00.
When MIRO is created the system allow us to enter more quantity and value that que have approved in PO.
Does anyone know a way to block it ? we could not post an MIRO with value and quantity greater than the PO item.
This PO have no MIGO to accept value because a type of PO was created to pay only certain services.
Best regards,
Ale

How to use (greater than) in web services call

Hello, I am trying to query a set of assets where the external unique ID is greater than 400,000. My existing code looks like
qryIn.ListOfAsset(0).ExternalSystemId = ">'400000'"
However, using this will return any asset record starting with a 5 or above as far as I can tell, I assume b/c it is comparing string data due to the single quotes infering data of type text (string). Is it possible to use comparison operators with numeric data correctly?
I posed this question to support and received the below answer:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <AssetWS_AssetQueryPage_Input xmlns="urn:crmondemand/ws/asset/"> <ListOfAsset xmlns="urn:/crmondemand/xml/asset"> <Asset> <AssetId /> <PurchaseDate/> <OwnerAccountId /> <ExternalSystemId>> '400000'</ExternalSystemId> </Asset> </ListOfAsset> </AssetWS_AssetQueryPage_Input> </soap:Body> </soap:Envelope>
Basically, instructing me to use &gt. I'm doing coding in .NET visual studio and not using the XML as above. However, I did try the following:
qryIn.ListOfAsset(0).ExternalSystemId = ">'400000'" which returned an error in the compiler.
Any help would be appreciated. Thanks.

Thanks for the reply. I would assume "external system id" is an integer, but, I will test on a custom field that I now is of type integer.
Could you take your same code and use a non-zero value for the operand? For example, could you try
objAccQryParam.ListOfAccount[0].CustomInteger0 = ">= '10'"; and let me know if that returns values that are greater than or equal to 10. Using a two digit number is important. Assuming you have data greater than 10.
Thanks!
