This is probably a real dumb question but when this statement runs I get an error "Object doesn't support this property or method." I'm at a loss as to why I'm getting this error. I don't find any axcreds anywhere in this database. This is a database I'm trying to convert from an .mdb to a newer version of Access.
Any help is appreciated. If more information is needed let me know.
I don't know what questions to ask. so please don't get mad at me.
In doing more research I find that the OLE Class = TreeCtrl and the Class = MSComctlLib I have no idea where to find this. I'm sure my axcreds are located there, but where are they???
When I converted the .mdb to .accdb it didn't bring across the treectrl tables. I don't know where to locate these tables so don't know how to fix my problem.

Hi Tom.
I hear you're struggling to know how to express your situation clearly enough that others will be able to offer assistance. Unfortunately, you're the only feet we have on the ground so we are relying on you to do a decent job. Without knowing more about your problem it's very difficult for us to advise on how better to explain your problem. Call it a Catch-22 if you like.
It still leaves us in the dark & depending on you to give more clarity.
Tom - could you list the procedure that this code is in?
It also may be an issue with the parent form.
Or it could be as simple as a missing reference (you said you are converting an older DB - You may have missed including the references).
Hope this hepps!
I've been doing more searching and I think what this has to do is with the treectrl When the ctrl was created for student creds however when I converted the .mdb database the treectrl axcreds data didn't come across. I don't know where that data is or how to bring it across to the new .accdb.
The following code is where the error happens. I can send more if need.Thanks - Private Sub Form_Load()

Tom,
I don't see where you've declared axCreds to be anything. You need:
before you can do anything with the nodes.
I hope this hepps!
Remember I'm converting this from a .mdb to .accdb I didn't write this program so I would hope that the code would be there. Even if I declare the axcreds where will I find the data that is supposed to be in this table or node.
Well, one step at a time. We need the system to know what axCreds is first. I also see a User-Defined Function: getCredTot(). You'll need to resolve the obvious issues before you can get into any details.
One method of troubleshooting I sometimes use (when importing huge chunks of code is to comment out the entire block and then uncomment one line at a time and compile. If there is an If...Then statement (or other nested set of lines) I uncomment the first and last lines, then go through each line inside.
This make take you some time to figure out what exactly is missing, as there may be multiple issues--you're just getting one error on one thing.
I've added the Dim axCreds as treeview, I also made sure I have the activex control Microsoft treeview control. It still stops on the statement Me.parent.axCreds.nodes.count Not sure where to go from here.
When I press Ok on that statement the form comes up but I don't have the data in the axCreds sub form.
Tom,
Please try to help us out here. The statement "Me.parent.axCreds.nodes.count" is not in the code you provided.

You also need to set the variable of axCreds to the TreeView control that you are using. I am having no issues accessing the count properties of the TreeView Nodes.
There seems to be much more missing from the VBA you've posted than what we can work with. The "Parent" indicates that your Form is a Subform on another form. The code you posted previously also indicates that there may be a subform on the form you are looking at.
Again, you are going to have to tackle this one small step at a time. It appears much of what is being referenced is not present.
In the code I just posted the parent form is QBPlus line 27. I've also removed the ' from line 28 and the program stops on the line also.
I still think we are chasing our tails by staying in this form. The issue is stemming from the parent. There may be issues there that need to be fixed before you can address them here on this form. Is this approach to troubleshooting making any sense, yet?
The error has always pointed to the parent form (note my second statement in Post #3). This is where you need to start.
Tom,
I still think you are approaching this from "the whole thing."
You need to begin with each small step:
Recreate the main form
Add the minimal amount of Code to open and close that form without a hitch.
Gradually add controls to your form
Add code for the controls
Add the TreeView control
Gradually add parts of the code to add functionality to the TreeView control
etc.
I still think this is a referencing problem. Either the control is not declared, set or referenced properly.
Again, in two minutes, I created a form with a TreeView control, dimmed a TreeView, set that object to the control, and was able to access all properties. Everything is there. I think you're just biting off more than you can chew at one time.
One step at a time--not many of us here have the time to work through "the whole thing." We are trying to point you toward where to focus your troubleshooting.
The nature of the error has to do with proper referencing. The code does not understand that the object is a TreeView control. It's that simple. That's the answer. You need to find out why it is not declared that way. I think there may be a module somewhere that is declaring it and setting it so publicly, but the code provided doesn't mention it anywhere. Once that public bit is uncovered, you will find success.
One more questions and then I'll continue with the step by stem. Where is the data kept for a tree ctrl or node. That's the part I don't understand. Is this tree ctrl or tree view like a table with columns and rows? and if so can I edit this like a table.
Usually a TreeView is filled "from somewhere." Usually from a Table. The user interacts with the tree view to manipulate the data in the table.
NB: I have not used TreeView controls, but an object-based language like VBA will treat it like any other object.

First I must congratulate Twinny for showing such patience. Above & beyond in my view.
As for a TreeView control, like Twinny I've heard of them, and seen themn in action, but I've never got my hands dirty with them at all. Nevertheless, in all the objects I've dealt with in Access that manage data there's a consistency to how the data is specified.
Forms & Repords have a RecordSource property and Controls have a ControlSource property. Have you looked to see if the TreeView Control has such a property? If so what is it set to, if anything?
TreeViews do not have a record source.

So it doesn't. Well, that's weird. I'd ask how it gets populated but that might allow the thread to be side-tracked so I won't here.
