Problems in LV 2010 Appbuilder Interop Assembly Function Editor

There seems to be a bug in the function editor for a dot Net Assembly in the LabVIEW 2010 appbuilder. If you begin adding, removing or rearranging function parameters, the parameter data at the right and function prototype don't match the parameter list.

Ah, I see. I had built a simple adding function and set x+y as the output then deleted x+y parameter and was not seeing anything but then if I deleted one of the input parameters I started to see what I believe you are seeing where the selected parameter would be x in my case but the name and VI input would be y. I will file a Corective Action Report on this. Thanks for pointing this out!

I 've read this link http://msdn.microsoft.com/en-us/library/ff182188.aspx but i still confuse and I don't know how to fix that case. I hope anyone can help that problems with some example
thank you

Hi ainunzariah,
You can try set the Embed Interop Types property to false for
AxInterop.VIDEOCAPLib,
Interop.VIDEOCAPLib and Microsoft.VisualBasic.Compatibility
in the References folder to see if it helps.

Problem in Adhoc Query's set operation functionality.

Hi Experts,
I am facing problem executing Adhoc Query's set operation functionality.
In Selection Tab, following operations are performed :-
Execute a query and mark it as 'Set A'.(Say Hit list = X)
Execute another query and mark it as 'Set B'.(Say Hit list = Y)
In Set operation Tab, following operations are performed :-:-
Carry out an Operations 'Set A minus Set B'.
which results in Resulting Set = Z.
Transfer the resulting set 'in hit list' and press the copy resulting set button.
In Selection Tab, Hit list is populated with Z.
And when output button is pressed, I get to see 'Y' list and not 'Z' list.
Kindly help.
Thanks.

Duplex printing problem in Word 2010 but NOT in Excel 2010

At the risk of repeating an old question :
I have Windows 7 Pro, Office Professional 2010 and an HP Officejet Pro 8600 Plus and two sided printing is a problem in Word.
Excel prints in Duplex by selecting "Print on both sides / Flip pages on short edge".
Word, though, with the exact same Setting, fails and the document is printed one two sheets of paper ... one side only. Seems rather bizarre.
Help would be appreciated.
Neil

Hi,
Which Word 2010 version do you use? Please try the Word 2010 14.0.4760.1000 version(We may upgrade or downgrade the version by install or uninstall the patches).
Next, we may try the workarounds which provide by other communicators, I copied here:
Workaround1:
File then Print
Go ahead and select manual print on both sides
Go to page setup, print options, and the advanced tab. Go all the way down and select "Print on the front of the sheet for duplex printing."
After printing the first set, I was able to just turn it 180 degrees and it worked just fine.
Workaround2:
As a work around I found if I ignore Words "Settings" and instead go into my printer properties, select the Finishing Tab, and select "Print on Both Sides (Manually)", the document will duplex print correctly. Requires 5 steps instead of 3

Problem with "new page as a copy" function in 4.2

Hi all,
I found several problems with version 4.2 in the functionality of "new page as a copy".
In particular, copying a page from another application, you lose the references to the template (eg template region, button ...) and these are replaced by a numeric code (eg 426589173 ... instead of "Region without Buttons and Titles") and, worst of all, the reference is lost to the buttons on the process conditions and branches.
Has anyone encountered the same problem? I never had any problems with version 4.1.1
Thanks
Stefano

A reference was created to embedded interop assembly

Hi
I have several warnings as below;
A reference was created to embedded interop assembly 'Accessibility' because of an indirect reference to that assembly from assembly 'System.Windows.Forms'. Consider changing the 'Embed Interop Types' property on either assembly.
What do I need to do to resolve these?
Thanks

Hi Y a h y a,
>>A reference was created to embedded interop assembly 'Accessibility' because of an indirect reference to that assembly from assembly 'System.Windows.Forms'. Consider changing the 'Embed Interop Types' property on either assembly.
Could you tell us the real project you were developing, WinForm or others? When did you get this error message?
Based on the error message, you would check whether it is related to the
Embed Interop Types property.

Interop assembly generates AccessViolationException

Hi,
I am writing a .Net application that needs to read/write to an FPGA via DMA. To do this I've written some LabVIEW VIs that do the read/write, generated a .net interop assembly and successfully incorportated this into my application. The APIs generated by the LabVIEW builder are
public static void ReadDma32(int Channel, int DataBufferSize, out uint[] Data, out int NumberOfEntriesRead, out int ReadResult);
where the channel parameter identifies which DMA FIFO should be accessed. The ReadDma32 calls block until they have any data to return so it's an asynchronous process. This all works fine until I want to read from two different DMA channels at the same time. I then get a AccessViolationException with the message "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I assume this is because of some marshalling issue when two different threads call the same method at the same time. I've tried changing the execution settings (reentrant execution) on the ReadDma32 vi but this has no effect.
Does anyone have any suggestion on how to solve this issue? My only idea so far is to remove the channel parameter from the method signature and have separate read/write dma methods for each DMA FIFO defined. Not very elegant.
thanks,
Ralph
public static void WriteDma32(int channel, uint[] data, out int writeResult);

I have created interop dll for labview VI's.
I am using interop dll in .NET environment.
The method signature is

I am calling as shown below
byte bComPort = byte.Parse("1");
byte bGasType = byte.Parse("6");
bool blnValueFromatFalse = false;

Problem in calling application module's custom functions

i m facing problem in calling application module's custom functions in jsp pages.
i'll highly appreciate any reply to this mail.
anant

Hi,
I also need to know how to call custom methods
within an application module implementation.
I have tried the <jbo:ApplicationModule id=am ...\>
then later in the JSP <% am.customMethod() %>
and this does not work. Any hints?I don't know how it works with JSPs, but if you want to call a custom method on a ApplicationModule, you first have to cast it to your custom class type.
Somethin like this:
MyAppModule am = (MyAppModule) sessionCookie.useApplicationModule( ... )
or maybe in your JSP
<jbo:ApplicationModule id="am">
<% MyAppModuleClass am = (MyAppModuleClass) am; %>
I think you forgot to do something like this in your JSP. Note that the code is not tested.
Hope that helps

We moved from Blackberry to iPhone for 120 services in 2010. We have just renewed the iPhone fleet. Security was the issue for the business that employs me (lawyers). When comparing the two, Blackberry performed without issue most of the time but we experienced a number of issues with the trackballs on individual phones. This was, however, the first of the Blackberry Bold models. The expense behind the scenes was one of the major factors for the move. It was cheaper to run Exchange and iPhones than Blackberry services. Our lawyers on the whole adopted the iPhones and a number have become quite proficient at using them. We ensured that we had a means to securely wipe and lock business phones. We chose Mobile Iron for this purpose but you will find other products to do the same job. Cost is probably going to be the deciding factor here. Our only negative factor was butterfingers resulting in smashed glass with the iPhones although I have had one user drown several phones.

You should check how you are initializing your variables in your testpanel class. You initialize your button correctly, but your other class variables are being overridden. As a result, your class variables still have a value of 'null'.

Can't create interop assembly with images as parameters

Hello,
I'm trying to create an "assembly interop.net " that contains imaq functions. This dll will be called from a c#.net application .
I've managed to do an "assembly interop.net" dll before that takes clusters in parameters, and it worked perfectly. But now when I try to pass images as parameters,
The images is interpreted as a "Refnum" type (I don't know what data type is that ). and when I try to build the dll I got this error message:
L'erreur -2628 s'est produite à : Nœud de méthode dans DatatypeXML_From_Control.vi->AB_ExportedAssemblyVI_Define_VI_Prototype.vi->AB_InteropAssembly.lvclasspen_Top_Level_VIs.vi->AB_Build.lvclass:Build.vi->AB_Application.lvclass:Build.vi->AB_InteropAssembly.lvclass:Build.vi->AB_Build.lvclass:Build_from_Wizard.vi->AB_UI_Frmwk_Build.lvclass:Build.vi->AB_UI_FRAMEWORK.vi->AB_CreateNewWizard_Invoke_CORE.vi->ABUIP_CreateNewWizard_Invoke.vi->ABUIP_CreateNewWizard_Invoke.vi.ProxyCaller
Raisons possibles :
LabVIEW: Une erreur s'est produite lors de l'analyse du document.
Please tell me if you have any idea about this subject.

If you need the image data, you need to convert the image to an array. The purple wires in LV are mearly pointers to memory. They do not contain image data in them. Converting the image to an array also insures that a race condition does not inadvertantly alter the image before you have a chance to process, or display it, if some other functions are acting on the image pointed to by the reference.

Problem rename sharepoint 2010 search service application admin database

Hi all,
i have a problem that hopefully someone has an answer to. i am not too familiar with sharepoint so please excuse my ignorance.
we have sharepoint 2010 on a windows 2008r2 server. everything seems to work fine. but as you know, the default database names are horrendous. i have managed to rename all of them, except for the "search service application" admin
database.
the default is: Search_Service_Application_DB_<guid>
the other 2 databases (crawl and property) were renamed without a problem.
we are following the article from technet on how to rename the search service admin db (http://technet.microsoft.com/en-nz/library/ff851878%28en-us%29.aspx). it says to enter the following command:
$searchapp | Set-SPEnterpriseSearchServiceApplication -DatabaseName "new database name" -DatabaseServer "dbserver"
however, i get an error about identity being null. no big deal, i add the -Identity switch and the name of my search service application. but the real problem comes the error it throws:
Set-SPEnterpriseSearchServiceApplication : The requested database move was aborted as the associated search application is not paused.
At line:1 char:54
+ $searchapp | Set-SPEnterpriseSearchServiceApplication <<<< -Identity "Search Service Application" -DatabaseName "SharePoint2010_Search_Service_Application_DB" -DatabaseServer "dbserver"
    + CategoryInfo          : InvalidData: (Microsoft.Offic...viceApplication:
   SetSearchServiceApplication) [Set-SPEnterpriseSearchServiceApplication], I
nvalidOperationException
    + FullyQualifiedErrorId : Microsoft.Office.Server.Search.Cmdlet.SetSearchS
   erviceApplication
when i look at the crawling content sources, i see "Local SharePoint Sites" and it's status is Idle. i even looked at this article on how to pause the search to no avail. (http://technet.microsoft.com/en-us/library/ee808864.aspx)
does someone know how i can rename my Search Service Applcation Admin database properly? or at least "pause" that service so i can rename it?
thank you all in advanced

If you want to have no guids for your search admin db, i recommend you check out this script :)
just delete your search service application (assuming you have just started)

After making sure that all services are up and running, I had to deactive and activate the "SharePoint Server Site Search" web site collection feature. Then the search started working for the time being.
However, it throws the error again after 8 to 9 hours. This has been happening for last couple of weeks. I also came to know from my windows server team that they moved the AD from one place to another. Since then I am having this issue.
The log file has the following error:

Problems of MacPro 2010 Mixing 2gb & 1gb memory together

Actually my MacPro 2010 12-core was running 8x1gb sticks before.
I just got 4 of 2gb sticks memory from a friend today.
And I do have problem mixing them with the original 1gb sticks.
Only plug 2gb sticks in Slot 1,2,5,6 - No Problem
When I have 2 x 2gb sticks in Slot 1&2, 2 x 1gb sticks in Slot 5&6 - Still No problem
However, when I have more them 4 sticks installed in the system, no matter when the combination is(sure I'm talking mixing 1&2gb sticks together), the MacPro just don't can't start and keep the front LED flashing.
So I just want to know anything I did wrong? Is that tri-channel can't run with mixing size of memory?
I know that's not good to mixing the memory in MacPro, I just want to know the reason behind(why it doesn't work), any advice?
p.s. 1gb module 1Rx8, 2gb module 1Rx4 (<- would it be the main reason?)

thanks for the advice
Both 1 & 2gb sticks are 1333 ECC, the only different thing is "Brand & Size" and "Organization", the original apple 1gb is 1Rx8, and the 2gb is 1Rx4. I heart that different organization mixing together will have a huge chance doesn't work properly, and I guess I'm having this issue right now, haha
I work on CS5 a lot, however 12-core is overkill for everything...I could do anything while I'm rendering the CS5 stuff, so I don't really need more than 16gb RAM to make it faster(for CS5) at this moment, but larger than 8gb should be way better.
The reason I try to mix them up(I know mixing is always fail), is just want to find out if it works or not, if it works, then it should be a bonus, since I can get them with a low price, and if it doesn't work, I can just give it back.
I just wanna make sure
*those RAM won't hurt my system(if it doesn't work properly with MacPro), and how can I make sure it?
*if I got no choice, I might get 8 sticks of those 2gb(since the price is really cheap) and sell all the 1gb sticks(if those 2gb RAM is no problem)
*Ideal for me is upgrade 4 sticks at a time, like 4x1 & 4x2, then 4x2 4x4, etc.. but I guess this wouldn't work...
