Creating event dll

Hi,
I creating a dll warpper to control ASIO drivers for sound cards. I want to generate an event on the buffer switch so LV can do the work needed.
I finished a first version using a fast while loop in LV, but I think that generating a event is a much elegant solution.
The problem I have now is to compile my code!! Indeed, I found some topics how to generate events from my dll. I have included "extcode.h" and some other stuff from "C:\Program Files\National Instruments\LabVIEW 8.5\cintools"
Now Visual C++ 2008 cannot link the functions :
Error 1 error LNK2028: unresolved token (0A000295) "void __cdecl PopulateStringHandle(struct LStr * *,char *)" (?PopulateStringHandle@@$$FYAXPAPAULStr@@PAD@Z) referenced in function "public: void __thiscall DriverCluster:nBufferSwitch(long,long)" (?OnBufferSwitch@DriverCluster@@$$FQAEXJJ@Z) DriverCluster.obj win32dll
Thank you for your help and I hope it's not a too stupide question

Solved!
Go to Solution.

Hi,
I cannot release the driver for the moment, I don't think my company would approve that I give the work I'm paid for... But to do the trick, you just need, the file asio.h from Steinberg. Then I found on the code-project, an exemple using asio driver in a c# code. Then you just need to creat a dll, some LV code and it over.
Right now I just doing optimization.
Good luck, Marc

BUS2001-'created' event not triggering

Hi experts,
I have created workflow for project release which is using BUS2001-delegated to zbus2001. im using the " Created" event but which is not trigeering the workflow and i tried checking manually using tcode "SWUE" its triggering. i Dnt know why its triggering while creating project in Tcode:- Cj20n... is there changes need to do in SWEc for standard event..
regards,
Roops

Hi Roop,
Can you let me know y you have created a subtype and delegated? Bcs according to your scenerio you dont require any custom business object, since you are using standrad event.
Can you let me how you are triggering this standard event and y you have configured in swec?
swec is for change documents.
Please elobarate the question.

BSEG.CREATED event not triggering when a document is posted in FB60

Hi All,
I have a requirement in which i need to post documents in FB60/FB65/FB01 tcode. But when i post the document in FB60 the event BSEG.CREATED is not triggering. I could not see any trace in SWEL. But when i park the document in FB60, FIPP.CREATED event is getting triggerd.
Can anyone tell me why this BSEG.CREATED event is not triggering.
Thanking you in advance,
satheesh.

Hi Viji,
Thanks for your quick reply.
We have maintained the required configurations in the system related to this. But still the event BSEG.CREATED is not triggering.
for this the alternative solution is to implement the BTE '1030'. But our functional team is asking us to check whey standard business object BSEG.CREATED is not triggering when we post a document. So that particular reason we are not able to find out.
Configuration maintained.
1) Created a workflow variant and assigned it to particular company code(OBWA and OBWJ).
2) Checked the 'Posting' release' and 'Release payments' checkboxes in the OBWA transaction.
3) Event linkage for BSEG is active.(SWETYPV)
Thanks,
satheesh

Saving photos to the web by creating events. Called the destination folder does not exist.

Hello,
I ask you for advice (assistance). A week ago I re-installed the PC and installed to the computer again Photoshop CS5. Everything works for me except for the function of storing images for web by creating events. Called me constantly destination folder does not exist. The problem I had before. I ask you this advice on how to solve this problem.
Thanks for the advice

hi,
i don't know if i integrate your code correctly, but it doens't work for me. I presently create skin for client and this plugin is really usefull for me.
i use win7 64bit home edition, and photoshop cs5
there is how i integrate this :
// EDIT ALEX GRENIER
function getPreferencesFolder() {
     var userData = Folder.userData;
     if (!userData || !userData.exists) {
          userData = Folder("~");
     var folder = new Folder(userData + "/xtools");
     if (!folder.exists) {
          folder.create();
     return folder;
function exportChildren(dupObj, orgObj, dupDocRef, folder) {
if (getCSVersion() >= 10) // CS3 Only
     // Create assets folder in Flex app's directory
     // var tempFolder;
     // tempFolder = new Folder (folder + "/assets/");
     // tempFolder.create();
     // EDIT ALEX GRENIER
     var tempFolder;
     tempFolder = getPreferencesFolder();
i put the code creating the folder in comment and put your code in place, i also put your function before the function creating file.
With the base code (without modification) photoshop is able to create my folder assets, but when it try to export the png, it export nothing, so i have a empty folder.
thank you,
Alex

How can I view my photos in "Events" like in iPhoto? How can I create events? I have 55,000 photos and 1700 events so the only way I can possibly manage my photos is using events that are one slide in size.

I have 55,000 images organized into about 1700 events. The only reasonable way to view my library is using events in iPhoto where each event has one image That still leaves 1700 images to sort through but that is a lot easier than 55,000 images. In the side bar is a folder with "iPhoto Events" but those views still show all of the slides. How can I create events and view my photos as events as in iPhoto? Events are critical for large libraries and has been my primary way to sort images.
Thanks!

I had a problem a couple of months ago when iPhotos suddenly rearranged the order of my Events (Why won't iPhoto let me arrange my photos?) . I was told "Use albums not events - events are not a good way to organize - albums and folder are designed for organisation and are very flexible".
Haha! I should have paid attention and read between the lines! My iPhotos were highly organised groupings - not according to date but the way I wanted them - and it was so easy to do! I see now that if I had them all in albums, as per the Apple Apologist suggestion, I wouldn't have this unholy mess I have been left with just to make iPhone & iCloud users happy. I am now going through Photos and making Albums (of what used to be in my Events) ... maybe I'll get this finished before they do another non user friendly update!

ICal - problem creating events in Exchange calendar

Hi All, this is a weird one to describe, so please bear with me...!
My client is on Snow Leopard at the moment, so does not yet have access to iCloud (upgrading remains an option but he is in no hurry). He is, however, having a confusing time of it using iCal on his Macbook.
He has linked iCal to his corporate Exchange account, and certainly he can view all the events within his iCal. However, when he creates a new event, it does not get created within the Exchange calendar, but rather in his local calendar, and then gets overlaid, visually, on top of the Exchange calendar. Consequently, this created event does not synchronise with his iPhone, because it is only "known about" on his local MacBook. Sorry if this sounds a little confusing, but do you guys see the problem?
Another, minor-ish, point is that the new event he creates locally always gets colour coded in a way that he seems to have no control over. Can anyone explain how the colour coding gets determined when a new event is posted?
To sum up then, he seems only to be able to read events in his Exchange calendar, but cannot add events in a way that they then get synced correctly.

I just barely had this problem. I restarted the program and it worked.

How to get updated and recently created events from google calendar in pl/s

Hello
I am able to get Google calendar events using pl/sql..I am receiving huge xml code(if there are more events),want only update and recently created events instead of getting repeated events.please help me in this regard.
Thanks

From the Google Calendar API online documentation:
"Retrieving an event again
If you want to retrieve an event that you've retrieved before, you can improve efficiency by telling Calendar to send the event only if it has changed since the last time you retrieved it."

Ical cannot create event in month view

iCal cannot create event in month view. Is this a bug?
I've tried double clicking in a day as I always did but nothing.

Ko be,
Application UI issues are in many cases, caused by a corrupt plist file.
Quit iCal, and try removing the com.apple.iCal.plist file from your Macintosh HD/Users/yourusername/Library/Preferences Folder. Since that Library is now hidden, you have to use the Finder>Go Menu>Depress the "Option" key>Library. Drag the .plist file to your desktop, and log out/in or restart and check iCal for functionality.
Also read Apple iCal 5 Office Software Review | Macworld for a description of Lion iCal.

How to create events in iCal

I know we can create events (like birthdays, anniversary etc.) from address book and sync it with iCal. What i want to know is how do I create an event (b'day, anniversary etc.) for a person who is not in my address book.

Greetings,
Create the event (just like you would any event) and set the repeat to every year and add it to the calendar of your choice:
Hope that helps.

I installed ios 7 in iphone 4 - i am not able to create event in calender , icon is not active

i installed ios 7 in iphone 4 - i am not able to create event in calender , icon is not active

You will have to upgrade your operating system version and possibly your whole computer. We cannot provide more information easily until we know more about your system.
Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..." Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
Apple does tell you about required equipment for the iPhone -- in 8 point medium gray type on a light gray box. The Store associates kind of automatically assume everybody is running a new model computer and the one I met when we bought our iPhone had never seen a pre-2008 Mac and was somewhat puzzled why anybody would own such an antique.

How can I get the soundcard to create event markers on voltage acquisition

Hello,
I'm new to Labview and I'm required to create a program that can acquire a voltage.. sounds simple.. the difficult part is that it needs to be able to create event markers on the data to indicate that a sound has occurred.
If I could somehow route the audio input to the trigger channel of my NI DAQcard6024E and set the threshold level it would work, but I can't find a way to do this.
To put it in a real-life scenario... what is happening is that I'm acquiring EEG (brainwave) voltages whilst presenting a series of auditory 'clicks'. We want to examine the changes in EEG that occur in response to these clicks. So I need to have some way of establishing exactly when the sounds were presented on the EEG data.
Hope somebody can help At the moment my VI can acquire voltage data continuously and write the files to excel, but I can't work out how to create event markers for when the stimulus occurred.
Thanks
Shane

I still think it should be possible to make a breakout cable. But I guess the person responsible for the Lab is not a technical person. Or he/she is more concerned about the equipment than the student projects. That is quite common among such personal.
I am also reading you are using a sound card for acquiring EEG. That is a very big NO-NO. This because sound cards are AC coupled. And this will limit the lower bandwidth to about 10Hz. So signals below about 10Hz is filtered out. EEG require a bandwidth from about 0.5Hz to 100Hz.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Help me I'm trying to create event listeners

I am trying to create event listeners
Whenever any keyboard event occurs the string s gets appended by a,c
or p.At the end of the program its supposed to print value of s
But s always happens to null.Please tell me how to correct it....so
that detection is possible for any case
import java.io.*;
import java.awt.event.*;
public class trial {
int x;
public static String s;
//OutputStream f1=new FileOutputStream("file2.txt");
public static void keyReleased(KeyEvent e)
s=s+"a";
public static void keyPressed(KeyEvent e)
s=s+"c";
public static void keyTyped(KeyEvent e)
s=s+"p";
public static void main(String args[])
throws IOException
char c;
BufferedReader br =new BufferedReader(new
InputStreamReader(System.in));
System.out.println("Entercharactes,'q' to quit.");
do
c=(char)br.read();
System.out.println(c);
while(c!='q');
// for(int i=0;i<s.length();++i)
System.out.println(s);

I suggest looking at the java tutorial. Your code completely misses the mark and you need to see examples.

When I save event it says problem in saving recurrence event and not allowing to save.What is the precise error that you are seeing and what Calendar interface are you using to create the event (Calendar Express/Comms Express/Outlook Connector/Mozilla Thunderbird Lightning Plugin etc.)

How to create event based process chains

Hi All,
I would like to know about event based process chains. In connection to this, could you please answer the following queries,
1. How to create events
2. How to link created event to the process chain in the same BI or BW system and as well as from
    externel BI system.
3. How link one process chain with other process chain (i.e, After completion of one process chain, it
    should trigger other dependent process chain)
Thanks and Regards,
Kotesh.

1). Doubt regarding first question.
For example, i would like to create time based event (it should be trigger daily at specified time),
where we have to maintain scheduling options while creating event.
When i checked SM62 there i found only two options a). Event name and b). Description.
Could please send any doucument link if you have.
Ans : You can use function modules like "BP_EVENT_RAISE" in a program and schedule the program to trigger.
2). For externel BIW system also same procedure we need to follow or any difference.
Ans : Externally you need to trigger the same event.
3). i found dependent process chain also had scheduling options as direct scheduling insted of start using meta chain or API. As you said dependent process chain should be mata chain. it seems dependent process chain may be Meta chain or Direct scheduilg.
Ans : Its your choice how you want to schedule it.You can either make that dependent chain a metachain or schedule it separately.
I found at the end of first process chain they kept one process like Raise event and second process chain connected with the help of raise event process event name. If you have any idea about this process could explain a bit more.
Ans : May be they are raising the event in the main chain and triggering the dependent chain using this event.
But Metachain is preferred for such thing.Though it does similar thing.
Hope this helps.
