<div> </div><div>Hi all, I am currently using VEE Pro 7.5, would like know what is the sequence of each routine/objects in VEE run first?
For example, i have 2 Userobj (Tom Userobj and Ben Userobj), which each of the userobj here perform the different task. I am here address them as D1 and D2. I place D1 on top of the D2. But when i call the pgm, i saw the pgm flow starts at D2 first then only D1.
How do i set which routine to start run and so on? And by default the pgm will run on which routine/object first?
Thank you for the previous doubt answered.</div><div>

<div>Jess,</div> <div> </div> <div>Vee will execture all unrestrained objects first starting from the upper left and going down the page. If you have an objects that has an input it will execute only when the input has a valid value. Once the unrestrained objects are executed then restrained objects will execute.

No license fee, its part of windows. Use .Net or ActiveX for your set and get routines.

One of the "selling" points behind ActiveX is that - provided you are using a windows platform - you can use it in practically any development language that has object manipulation capabilities. Having said that, there are some development houses out there that will restrict you to a certain language, though this is far and few between (and you can get around that too). Be aware though, that you may also have to pay for a license to use the control outside of the development environment, so check the documentation carefully
Vee (starting with version 5 or 6) has the capability to use ActiveX; so in the end, it's up to you.
 
Different methods: .NET vs. ActiveX
If you have Vee 7.5, the .NET assemblies are possibly the easiest route to go (better tools for the job within Vee); followed very closely by decent ActiveX controls.
If like me you're stuck with a prior version with only ActiveX support then it's not too difficult, although I would reccommend that you read the ActiveX control's documentation with regards to features you need in your project before getting started.

We use .net assembly references and the oleprn library, part of Microsoft windows (you might have to browse to c:windowssystem32oleprn.dll).

Anybody out there ever do any work with SNMP Protocol? I've got a bunch of CATV headend equipment that I need to control and 90% of it uses SNMP. I've researched on the internet and found various tools available. Mostly ActiveX controls that say they work with C++ or VB. I'm wondering if any environment that can use ActiveX could use these tools, in other words can I do it with VEE?

I will admit that I have seen this happen otherwise but I was using the information in the Vee help and what I was told by a Vee instructor.

The following is a summary of the propagation rules that VEE follows when a program executes in VEE 4 or higher execution mode:
HYPERLINK "mk:@MSITStore:C:Program%20FilesAgilentVEE%20Pro%207.0vee.chm::/imagecbullet.gif"image/cbullet.gifÂ Data flows through objects from left-to-right -- sequence flows from top-to-bottom.
HYPERLINK "mk:@MSITStore:C:Program%20FilesAgilentVEE%20Pro%207.0vee.chm::/imagecbullet.gif"image/cbullet.gifÂ All data and XEQ input pins must be connected.
HYPERLINK "mk:@MSITStore:C:Program%20FilesAgilentVEE%20Pro%207.0vee.chm::/imagecbullet.gif"image/cbullet.gifÂ Objects with no data input pins or sequence input pin connections operate first.

While it is true that in VEE you would constrain (or sequence) the objects to control the
execution sequence, I do not believe that...

"VEE will execture all unrestrained objects first starting from the upper left and going
down the page"

See attached example which disproves this notion of object's position dependency in the
workspace.

The ONLY principle that a VEE code operates is thru the method of constraints (i.e.,
sequence and data flow).
