How to call a DLL function that has need of an array initialized structures which can be written in by the DLL?
I need to call the following function in a C DLL:
__declspec (dllexport) int MSIL_EnumSpectrometers (SPECTROMETER_ID * spectrometers);
where the only parameter is a pointer to:
typedef struct
{
tank model [32];
series char [32];
Channel int;
} SPECTROMETER_ID;
Before LabVIEW 2011 I would use a CIN allocate the memory and call the function, but in LabVIEW 2011, the INC has been deleted and I have to use a library function node call instead. When I go to set the parameter, it seems that I need to set the type to "Adapt to the Type" and data for 'Pointer to data in table' Format, then pass an initialized array of SPECTROMETER_ID with the many elements he so the DLL can fill the table with data. (See the attached picture.) When I do that, however, it blocks LabVIEW desktop. I guess it is because the DLL is corrupting the memory space of LabVIEW, but I don't see why, because I'm basically passing in a void pointer to an array initialized in the right size. Note that the first node of NSI returns the number of elements required in the table. Anyone have any idea what I'm doing wrong here?
In LabVIEW, when a table is in a cluster - cluster don't detain actually table but sort of a pointer that points to the table. If you need the cluster to contain 32 to 32 Add to the cluster. See the VI attached to how it's supposed to be done.

I have a host in my cluster I have designated as the place where I would like my vCenter server to reside. I created a rule of affinity for that to happen. I would like to have my models are on the same host. However, I don't see a way to do this with affinity rules as templates are not displayed in the list of virtual machines that can be chosen to create a group. I guess that ther eis a way to do it.
To ensure that guests with templates is not extinguished by DPM, you must override the DPM settings for this host setting DPM to disabled.

Hi everyone, yet once landed upward with a problem.
After trying many things to myself, finally decided to post here...
I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.
It works very well with a single table. The problem now is that I cannot do the same with 2 tables.
Because the tables have the same number of columns and the columns names.
Here are the 2 tables with column names:
Table-1 (MONTHLY_PART_1) Table-2 (MONTHLY_PART_2) SL_NO SL_NO MODEL MODEL END_DATE END_DATE U-1 U-1 U-2 U-2 U-4 U-4 .......... ........ .......... ........ U-20 U-20 U-25 U-25 Given that the tables have the same column names, I get the following error :
402 error at line 103, column 4
required aliases in the SELECT list of the slider to avoid duplicate column names.
So how to export data to excel that has 2 tables with the same number of columns and the column names?
Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?
Help me with this please.
Thank you.
Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?
see you soon

How to remove a discoverer report that has a status of running query
Thank youHi 925907,
I think you would work with your DBA to kill the session associated with the workbook running.
A query like this will provide your DBA with all the necessary information, it must:
Select
vs.*
Of
v$ session vs
where
vs. Program like 'dis51ws@% ';After the session was killed, it is a deletion of standard workbook (select file > open workbooks, and then right click on the name of the workbook, and then select delete).

When I updated the shock of the clans for my daughter on his iPad, it has its own apple ID. and iCloud, my ID apple came on his id for the update, where it has its own apple ID now. Please can someone tell me why the update came not through its ID thanks
It seems that if the application has been downloaded on his iPad while it is connected to your Apple ID. If so, he'll always want to be updated with your Apple ID.
You must remove the application from his iPad and then download it again while it is connected to its own code of Apple.

How to call a dll from another dll functions
Hi, can someone please tell me some examples or instructions on how you go about calling functions from a dll from another dll including the IUR. The two DLLs were created with labwindows cvi.
Thank you!
Hi Sinnas,
You mention that you use a UIR. A DLL does not have a file UIR as part of it.
DLL1
Instead, when you build the DLL first, we'll call it DLL1, you create a header or the files that contain functions that you want to the client code to call. When you build DLL1, you must export the file DLL1 function for his client to call code header. Whatever the calling code is (a GUI or another DLL), you must include in the exported DLL1 project headers AND DLL1 .lib file generated when you generate it.
DLL2
DLL2 will contain in its project, the header file exported for DLL1, DLL1 .lib file - that gives it the feature in DLL1. The code can then call any desired DLL1, but as DLL1, you should now have a header file that exports the functions of DLL2 desired HIS client code to call. When you build DLL2, you create a .lib for THAT DLL file to include in the code of the final customer.
GUI
The final customer code will be a few GUI that you create to call DLL2 functions will have the UIR upper layer file. It will include the exported DLL2 header file and the file .lib DLL2 in his project. It can then call any function of DLL2. It is the most clean way to have 2 dll working together.
NOTE: You can create a GUI to test the lower level DLL1 functions before placing DLL2 in the system. In fact, it's a good idea to do it - you want to make sure your lower level DLL1 code works properly before construction above it.
Simple diagram
Client code (calls to functions of the DLL2 header files) exported
--------------------------------------------------------------------------
DLL2 (DLL1 function calls exported in header files)
--------------------------------------------------------------------------
DLL1<-------------------- you="" can="" also="" create="" a="" gui="" that="" only="" calls="" dll1="" exported="" header="" files="" to="" test="" out="">-------------------- >
A suggestion... I create my dll in debug mode and use them to test my code. But I also build as static libraries. When I do the final version of the system, I use static libraries. They are built with the final executable and don't require additional files to install as do the dll. When you install your system with DLLs, you must include all THE dll and they must be installed in the folder Windows/System32 of the target computer.
I hope this helps...

Create a directory tree: how to call a global function from inside a for loop
Hello
I am trying to create a workflow that will create a directory tree in vCenter.
Concept:
Basically, I am trying to execute nested for loops for each level of the tree to the caller a global tree.
Problem:
The 1st loop for works and creates the file 'Dev '. The second loop for does not work with error message:
[19:16:16.219 2013-06-27] [I] building Dev folder
[19:16:16.474 2013-06-27] [I] directory Built: Dev
[19:16:16.476 2013-06-27] [I] the records building servers
[19:16:16.480 2013-06-27] [I] TypeError: cannot find the createFolder function in dev object. (Workflow: TEST_TNG_New_Site_Folder_Structure / Scriptable task (item2) #36)I think it has to do with JavaScript not being not able to call a global function in a nested object (I'm not a programmer and don't know JavaScript, so don't shoot me on that :)
Code: (will clean this up once I do work)
var folderBase is ['Dev', 'DMZ', 'Prod', 'UAT'];.
var folderT1 = ["servers", "Jobs"];
var folderT2 = ['Window', 'Linux'];
var folderT3 is ["Repo2', 'Repo3', 'Repo1', 'Repo4'];.
var folderT4 is ["T1", "T2", "T3"];.
Create the files folderBase level
for (var i = 0, l = folderBase.length; i < l; i ++) {}
var rootFolder = parentFolder;
buildFolderTree (folderBase [i]);
Create the files folderT1 level
for (var j = 0, l = folderT1.length; j < l; j ++) {}
var rootFolder = folderBase [i];
buildFolderTree (folderT1 [j]);
Create the files folderT2 level
for (var k = 0, l = folderT2.length; k < l; k ++) {}
var rootFolder = folderT1 [j];
buildFolderTree (folderT2 [k]);
Create the files folderT3 level
for (var x = 0, l = folderT3.length; x < l; x ++) {}
var rootFolder = folderT2 [k];
buildFolderTree (folderT3 [x]);
Create the files folderT4 level
for (var y = 0, l = folderT4.length; y < l; y ++) {}
var rootFolder = folderT3 [x];
buildFolderTree(folderT4[y]);
}
}
}
}
}
function buildFolderTree (folderName) {}
System.log ("Building folder" + folderName);
rootFolder.createFolder (folderName);
System.log ("directory of frame:" + folderName);
}
Any help will be appreciated.
Thank you

Hello
The createFolder() method returns the object VcFolder to the folder just created, for the new file to be used immediately. Here is how I modified the code:
Create the files folderBase level
for (var i = 0; i)
var newBaseFolder = buildFolderTree (parentFolder, folderBase [i]);
Create the files folderT1 level
for (var j = 0; j)
var newT1Folder = buildFolderTree (newBaseFolder, folderT1 [j]);
Create the files folderT2 level
for (var k = 0; k)
var newT2Folder = buildFolderTree (newT1Folder, folderT2 [k]);
Create the files folderT3 level
for (var x = 0; x)
var newT3Folder = buildFolderTree (newT2Folder, folderT3 [x]);
Create the files folderT4 level
for (var y = 0; y)
var newT4Folder = buildFolderTree (newT3Folder, folderT4 [y]);
}
}
}
}
}function buildFolderTree (parentFolderObj, folder_name) {}
System.log ("Building folder" + folderName);
var newFolder = parentFolderObj.createFolder (folderName);
System.log ("directory of frame:" + folderName);
return NewFolder;

C# - run a function that has no constuctor - is not possible?
Hello
I have a C#-DLL that contains a form with builder class. I can open and run an LV form by using the "Select. NET-Builder ".
Then I have a second class in the DLL that executes only the form but does not have an own constructor.
Now here's the problem: I see the name of the class in the 'Select. NET-Builder "-popup but I can't he choose as there is no constructor for this class."
Question now is: How can I run the functiions in this class?
