Could you use ActiveX controls to achieve the effect you like?

For example, you can use Shockwave Flash Object controls to load or
call some Flash motion pictures to achieve the effect you like!

They may also run on opening the VI (ie: even before you have run the VI...)

How can i use activeX Control in labview?

how can i use activeX Control in labview?
please describe me step by step.
thanks.

Well..that was quite helpful..but now I'm encountering certain problems. I've attached the VI I've made.
I don't need sound at the moment so I dropped it. (Although I tried to play it..but all I could hear was a very annoying sound.) Secondly I don't want to display any date or time..so i dropped that property too.
Now when I run this Vi...the webcam turns on, the screen of videocapx pops up..then the webcam light goes off..and another pop up appears saying..labview is not responding..and i have to close it reluctantly.
I haven't placed the stop capture property in this vi. i checked it by placing it too..but that doesn't work.
I would like to notify that my actual task is to acquire image and then compare it with another one already present on my pc. I want you to please help me out..solve my first query then I'll proceed with the latter part.

How does labVIEW use ActiveX controls?

How does labVIEW use activeX controls?
I recently wrote an activeX control in VB and noticed that it would not work if the control was set so that its properties could not be set in ambient mode. This may suggest that labVIEW uses some activeX controls only in ambient mode.
Is this the case or are there more complexities?

Dan,
Which version of LabVIEW do you have?
As per the KnowledgeBase bellow, in versions of LabVIEW prior to 5.1 you would get errors accessing the ambient properties.
ActiveX Controls in LabVIEW 5.0.1 Containers Cannot Access Ambient Property
Do your controls use the Ambient.UserMode to determine when the control is being used in a development environment? When embedding ActiveX controls into a container on the front panel, by default, the ActiveX control generates and responds to events, i.e. it is running, even when LabVIEW is in edit mode.
Right-click an ActiveX container and select Advanced»Design Mode from the shortcut menu to display the container
in design mode while you edit the VI. In design mode, events are not generated and event procedures do not run. The default mode is run mode, where you interact with the object as a user would.
Information can be found in the LabVIEW help files

How to control and display video from IP camera using ActiveX control over Internet.

Hello,
I need to control my IP cameras over the internet. I need to log into the cameras and then display the video. There's an ActiveX control registered on the computer and works fine with IE to access and control the cameras. Controlling the cameras using IE works fairly well, but there are some quirks that I'd like to eliminate by using my own custom code.
Has anyone created a vi that controls a Foscam FI8905W over the Internet? I’ve attempted, but I keep getting a catastrophic failure when I try to call ManagementConnect Method in the DVM_IPCam2 ActiveX Control Module V1.0. I'm not sure whether I need to establish an IP connection with the cameras first, or allow the ActiveX control to establish it for me.
Some example code would be greatly appreciated. Running LabVIEW 2011 on a Win7 32bit. Even some code used to control a similar device using ActiveX over Internet would be helpful.

I have an example vi for interfacing to the foscam activex.
I plan on using mouse click events within the activex window to trigger the PT function.
I only have the basic up/down/right/left directions and not the down-right/down-left/up-right/up-left in the enum. You can load the camera's web page and view the source to see the Java script code that uses the activex control. There are definitions for the other directions.
I had to mark the control as "Disabled" to keep click events from going to the activex control. If I double click the control, it goes full screen. If I then click on it to get out of full screen mode the video never returns or returns to the wrong spot in the VI.

I'm an oracle developer and My name is milton datta.I cant' use activex control in forms.Pls. anybody would help me how to use activex control in developer forms.If possible provide me with some examples.
my email address is [email protected]

Download the Oracle Forms demos and you'll see a sample.
Also read the documentation for Oracle Forms 6i the developer guide has a section about Active/X.
Just remember that they will not work once you take your Forms to the Web. So think twice before you use them.

Using ActiveX controls in GUI application, which uses TestStand API

When using ActiveX controls in TestStand Operator Interface GUI,
CVI reports User Interface Library error no.-143:
"ActiveX control Error" on attempt to load panel, which contains ActiveX controls.
The same code, which takes care of user interface, but not references
TestStand ActiveX API (i.e. not creates TS Engine), works properly.
What's wrong?

Hello again Misha,
Sorry about my previous answer, I overlooked the fact that you were saying this error was caused by placing ActiveX controls in your Operator Interface (OI) GUI (as my example shows I thought the problem was with GUIs displayed from step code modules).
Nevertheless, the problem is still being caused by the same issue, and is solved in a similar fashion. The source for the CVI OI initializes the TestStand engine before it loads/displays the UI panels. The calls to initialize the engine seem to be CoInitializing the main GUI thread as multithreaded apartment (MTA) mode whereas you will need it to be single threaded apartment (STA) mode in order for the ActiveX control container to work properly. The TestStand engine is compatible with either modes, but only one can be in place at a given time. If we CoInitialize the OI's main GUI thread as STA this will solve the problem (the subsequent attempts of setting it to MTA will fail, but again this is ok since the engine is compatible with STA).
In order to perform this functionality you will need to put a call to CoInitializeEx in the main function of the CVI OI source (this will also require that you #include the "windows.h" file at the top of the source also). Here is what the main function in your main.c file for the CVI OI will look like once you have done this:
int main(int argc, char **argv)
int retval = -1;
sArgc = argc;
sArgv = argv;
if(InitCVIRTE(0, argv, 0) == 0) /* Initialize CVI libraries */
goto Done; /* out of memory */
// Intialize main GUI thread as STA to prevent other attempt to make it
// MTA, which will not allow ActiveX controls to be used.
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
/* initialize the test engine */
if(!InitEngine())
goto Done;
if(!InitErrorDialogStrings())
goto Done;
if(!InStandaloneExecutable() && !DisplayRunningInEnvironmentWarning())
goto Done; // get out now
if(!ProcessPreLoginCmdlineArgs())
goto Done;
if(!CfgFile_Load())
goto Done;
if(!CfgFile_RestoreOptionSettings())
goto Done;
if(LoadGUIPanels() < 0)
goto Done;
if(!InitFileQuickList())
goto Done;
/* set initial gui state */
if(!InitGUI())
goto Done;
RunUserInterface();
retval = 0; /* normal exist status */
Done:
/* cleanup */
SeqFileList_DeleteAllSequenceFileRecords();
ExeList_DeleteAllRecords();
IconList_DeleteIconList();
SaveAndCleanupFileQuickList();
CfgFile_SaveOptionSettings();
CfgFile_WriteAndCleanupForExit();
AdaptList_DeleteAdapterList();
DestroyToolMenus();
CloseEngine();
FreeErrorDialogStrings();
return retval;
Note: Remember to #include "windows.h" at the very top of the main.c file and to include ole32.lib in your project file list in order to link in the definition for CoInitializeEx.

Unable to print crystal report over web using ActiveX Control

Post Author: jimmyp
CA Forum: General
We have a problem with printing crystal report over web using ActiveX Control. When clicking print button, it only shows a blank dialog web crystal viewer page without any error. The page just simply hangs. We installed the PrintControl DLL and enable all the security setting for ActiveX Control for IE. It still does not print. Does anyone know why?
Environment.

Using a control item in the control block

I want to do; using a control item in the control block, I can control the item in the detail block and I can navigate anywhere in the detail block on the condition.
For example, I have a master block ,a detail block,a control block.
before move the focus from the mater block to the detail block, the focus goes to the item in the control block and run a trigger and set properties for the items in the detail block, then navigate to the item in the detail block using go_item(?).
Is it possible? if possible would you give me some example or idea?
thanks a lot.

well u can.May be you want to perform add / delete/ update through your buttons in forms

Can you use ActiveX controls in PL/SQL?

I am trying to find a way to start email from within a database trigger. Someone told me I could use an ActiveX Control (custom made by a colleague). Although I have never worked with ActiveX or OLE, I know that it is possible to use them in Forms. Is is also possible to call an ActiveX in PL/SQL? How? And if it is impossible, could someone tell me another way to start email (the application is to be implemented in a Windows NT Network).
Lots of thanks for any answer or advice,
Joeri Folman

Joen,
I am not totally sure what you mean when you say 'start email', but you should check out the utl_smpt packages in the database. They can be used to send email messages from the database. I believe that you need to have an email server (like sendmail) running on the machine for these to work correctly.
Check out Oracle Built-In Packages by Steven Feuerstein. Steven also has a real good book on PL/SQL programming that you may find helpful.

How to extend the JVue applet class using ActiveX Control

My SR recommendation was to post this here:
) How to Extend the JVue Applet class
This is the preferred solution. However, when using the ActiveX control, my derived JVue class that is specified in autovue.properties is not being instantiated.
Your ActiveX bridge looks like it's hard coding a "new JVue()" which means I have no integration hook using the ActiveX control.
To reiterate, if I extend JVue to add functionality and specify it in the autovue.properties, it is picked up when I run it standalone but if I use the ActiveX component, it is not being picked up.
I have already read all the documentation, have had web conferences with Mahmood and Jeff Chapman and the engineering staff who recommended this approach as the preferred option.

We have a need to override certain VueBean/JVue method calls to meet our document handling(documents need to handle metadata information and hence change the document loading cycle, ie markup loading/XRef resolution is dynamic). Also the invokeAction/invokeSubAction do not allow parameter passing(which we have requirements for certain actions again due to metadata) so we would like to override the invokeAction method to include custom processing(we will encode the action with parameters).
We are already using Custom VueActions for other simpler UI event handling that don't have parameter requirements.
As I said above, these use cases were relayed to the engineering team and senior staff members in early December and we were told that we could proceed with overriding the main class in the autovue.properties file. I have SR(s) opened with a long thread detailing this so I really don't want to go through this again.
A custom VueAction does not seem to work because it binds to late in the object call/event stream.

Problems using ActiveX controls

Hello all,
I bought a set of ActiveX controls provided with a installation routine.
Using those controls within LabView after installing them were no
problem, but for distribution purpose I have to install those ActiveX
controls manually.
So I tried to do it on a separate computer by registering the ActiveX
controls with regsvr32 [regsvr32 ]. But the attempt to
start a LabView program where these controls were embedded ended with
the error message "error opening document" (ole_lv5container) and "error
510 occurred while loading ActiveX control ..."
I'm working with Windows NT 4.0 and LabView 5.0f2.
Does anyone know, what I made wrong?

How Use ActiveX Control Item!

Please Let me know how use OCX Control with ActiveX Control Item in forms6i,
and send me Sample code(*.fmb).
Especially, I want to know how handle 'Event' of OCX Control in forms 6i.
When use VBasic, code is descibed in 'Event' of OCX Control, and then how handle 'Event' of OCX Control in forms 6i.
return to mail - [email protected]

I think that if you use an activeX container, property and invoke nodes will work for the document/file or whatever you have in it, so I recommed you to use references to the file you want to use, open an activeX reference in the block diagram, and pass this reference to open, write, save and exit. This can be done easyly using the invoke and property nodes you already know... If not, check for errors between them, sometimes one error makes the rest of the code not to work... Hope this helps.
If you want me to check the program, you can send an example here, but be sure it's LV 5.0, I've nor 5.1 nor 6.0, it can be a way of knowing the problem.
