Trouble "Leveraging .NET in SLX 6.2"
Posted: 13 Mar 07 12:11 PM
|
fiogf49gjkf0d Hi all. 
I am following to the T the "start to finish" video demo of Leveraging .NET (C# though),
When I click to view the tab, AXFormChange is being called, and my .NET DataGridView appears.
However, when I click to go to next account, only the Native Plugin part refreshes.
So, Label1's Caption changes to the new ACCOUNTID, however the .NET part, which should come up with the AXFormChange, does not refresh. In fact, it goes away entirely, and doesn't come back. I can make it always come back if I have a button to refresh it.
It seems like AXFormChange is just not getting called at all. AXFormMouseMove is the only Sub that seems to get called a lot for me (although that can't be the right place to put the code.) Here is the Script in my Saleslogix form:
option explicit
Sub AXFormChange(Sender)
Dim loader
If Application.GlobalInfo.IndexOf("EmbedControlObject") = -1 Then
Set loader = CreateObject("DccSlx.EmbedExternalHistoryControl")
loader.Init Form.HWND
loader.AccountID = Form.CurrentID
Application.GlobalInfo.Add "EmbedControlObject", loader
Else
Set loader = Application.GlobalInfo("EmbedControlObject")
loader.AccountID = Form.CurrentID
End If
End Sub

fiogf49gjkf0d Everything looks right for the code you've posted.
Is this on a tab or on the main detail screen?
You say you have a label or something bound to the primary ID field and it is properly changing when moving from record or record?
If you put a "stop" statement in right before the "IF" block, and go into the debugger to step through the script, does it properly fall into the "else" part on subsequent record changes? |

fiogf49gjkf0d This is on a tab at the account level only for now (I plan to make one for Contact and Opportunity levels once I get this working).
I have a TLabel called Label1 which has its Caption attribute bound to ACCOUNT:ACCOUNTID and so yes, that does change properly when moving from record to record.
Thanks for the tip about Stop. Rebecca Harris thanks you too on that one.
It does seem to drop correctly into the Else, however it does so twice.
(On initial create, it drops first into the If, and then a second time into the else, even on the first time).

fiogf49gjkf0d okay. I got it sort of working, so perhaps the error is in my .NET user control.
It works if I call this (again) in the Else part (after getting loader from Application.GlobalInfo and before setting the CurrentID):
loader.Init Form.HWND
So maybe I'm just not saving the parent right in the loader object. |

fiogf49gjkf0d Sounds like you might not be keeping a reference to the UserControl in you .NET assembly. So, each time you need to recreate and embed the control since you've lost the reference to the original one. Just a guess, but it would have to be something like that.
Feel free to post your C# code that does the embedding as well if you need to. |

fiogf49gjkf0d Now it's working. Here's the new code below. I just went back and simplified out extra stuff that I had put in there. I must have taken out something that was causing problems (code that was meant for future use: reload, opportunityid, contactid, buttonclick). As before, closed Saleslogix completely and reinstalled the ClassLibrary1.dll using a batch file which I will also post.
 Seems brittle that it should "just work" now even though I didn't consciously "fix it".

fiogf49gjkf0d Now this is weird. With the Plugin open in Architect, I did Save As and gave a new name. Now they don't work as before (copied and original), even with now code. It is like a CTRL F5 isn't always enough to get new scripts? |

A CTRL+F5 does not clear globals, so if you've saved an instance of your .NET object in a global, it will still be there after a CTRL+F5 - this is probably what you are seeing. |
