GetOpGroupDataInExternalFile

[rocheey1]

I'm having a bit of trouble getting 'GetOpGroupDataInExternalFile' to run with success.

 

Using X7, and attempting to read in an X7 file which contains Operations. The function always returns FALSE.

 

dropped the following code into my Run Function:

 

	 Dim FileSpec As String = "C:\TMP\TEST.MCX-7"
	 Dim success As Boolean = False
	 Dim OpData() As ExternalOpsFileData = Nothing
	 Dim GroupData() As ExternalGroupsFileData = Nothing
	 success = SearchManager.GetOpGroupDataInExternalFile(FileSpec, GroupData, OpData)

 

Any idea what I'm doing wrong ?

Do you end up with any data n the GroupData or OpData objects?

 

Could you mail me your TEST.MCX-7 file?

 

SDK <at> mastercam <dot> com

The GroupData and OpData arrays come back as NOTHING ["If IsNothing(GroupData) Then"...] ... which is the way they were sent out to the function.

 

I just emailed the test.mcx-7 file out

 

Thanx, Roger

Maybe the path to your file should be:

"C:\\TMP\\TEST.MCX-7"

 

or maybe:

Dim FileSpec As String = @"C:\TMP\TEST.MCX-7"

The double backslashes had no effect; Function still returns False, both arrays are still Nothing.

Vb.net wouldn't even allow the second variation.

The GroupData and OpData varaibes are "out" variables, as the GetOpGroupDataInExternalFile method fills them in with data.

Here they are set to "nothing" (or null for you non VB programmers).

That's not going to work, as they need to be intialzied to "someting"

 

 

So instead of this -->

Dim FileSpec As String = "C:\TMP\TEST.MCX-7"
Dim success As Boolean = False
Dim OpData() As ExternalOpsFileData = nothing
Dim GroupData() As ExternalGroupsFileData = nothing
Success = SearchManager.GetOpGroupDataInExternalFile(FileSpec, GroupData, OpData)

 

You need to initialize them as "empty" ->

Dim FileSpec As String = "C:\TMP\TEST.MCX-7"
Dim success As Boolean = False
Dim OpData() As ExternalOpsFileData = {}
Dim GroupData() As ExternalGroupsFileData = {}
Success = SearchManager.GetOpGroupDataInExternalFile(FileSpec, GroupData, OpData)

 

A side note:

GetOpGroupDataInExternalFile allows one or the other to be nothing (null), which tells this method not to bother retrieve that (Group or Op) data.

 

If both are null, you've told it to not bother with either, so you get nothing in the (2) output variables and the return in False.

It should only return False, if…

• The supplied file name “bad” (does not exist).

• Both of the supplied GroupData and OpData variables are null.

• Mastercam is not in a Machine Mode (it will not work if only in ‘Design’).

• Something horribly unexpected has gone wrong.

 

If you really need to use the GetOpGroupDataInExternalFile method in X7 - please contact me -> SDK <at> mastercam >dot> com

Haa haaa... I can imagine a layman reading this post .... that changing from "Nothing", to "Empty", makes it "something" :/

 

Thanx again, Roger
