If anyone wants to test this out to verify its a true bug it would be helpful:
Create a tab control.
Place a treeview control (with checkboxes = Yes) on one of the pages.
Populate the treeview.
Check some boxes.
Move to the next page of the tab control.
Return to the page with the treeview.
Viola! The checkboxes you checked previously are all unchecked.
(Not just visually, but property-wise as well).
One step forward, two steps back.
Actually, the work around is to remove the treeview from the tab control and then change the Visible property of the treeview to False if on a different tab page, and True if on the page you want it to display on. But c'mon why can't it work the way you'd expect it to work!
I have a form with a number of controls with code behind - this works as required.
However, recently I decided to use a tabbed control to hold the controls and simply cut/pasted these control onto one of the pages of the tab control. The events now no longer fire as they did and I have no functionality on the form - the code still exists in the design of the form though..... any ideas?
I cant seem to type after a couple of lines as the page moves to the top, i have to keep pressing shift and F2 to complete the typing. Even with Shift and F2 box im unable to click enter to go to the next line as the box closes.
So if i start typing in the pic FM2 then FM1 appears automatically. Basically i cant use the memo control like a word document for my users.
I just discovered TreeView Controls after browsing through this site today...in a word, awesome!
I've done alot of searching, and it seems that most of the discussion on TreeView is at a data level.
What I am wondering is if a TreeView can be used as a database navigational pane...ie switchboard, where the nodes are comprised of individual forms and/or reports, that when clicked, opens the associated form/report?
Does anybody have a sample db where this is being done or can somebody give me some tips on doing this?
I have a sample treeview.mdb in 2000, and I can freely create the parent and child nodes. That is the extent of my knowledge. I don't know how to make the nodes "actionable".
Hi I am trying to create a treeview based on a table that I created. I am trying to create a treeview that fills the treeview recursively but for some reason I am only able to see the parent node and not the children
Here are the specs that I have so far
I have a table called "tblTreeview" I have tree fields "txtID" "txtNode" "txtRelationship" I also have a form called "frmTreeview" I named my treeview control "axtreeview"
here is the code that I copied off the link that I referenced at the beginning of this thread.
The only thing that is different is the name of the fields.
'--Beginning Code -- Private Sub Form_Load() Const strTableQueryName = "tblTreeview" Dim db As DAO.Database, rst As DAO.Recordset Set db = CurrentDb Set rst = db.OpenRecordset(strTableQueryName, dbOpenDynaset, dbReadOnly) AddBranch rst:=rst, strPointerField:="txtRelationship", strIDField:="txtID", strTextField:="txtNode" End Sub

Set nodCurrent = objTree.Nodes.Add(, , strKey, strText) End If ' Save your place in the recordset so we can pass by ref for speed. bk = rst.Bookmark ' Add employees who report to this node.

I use Access 2010 on Windows 7 64b to create a form with a Treeview control. However, this control is missing from the list of controls activix. How can I add?
I downloaded a sample treeview application I have modified most of its to suit my need, except one thing. I want link parent/child node the main form to the main form through a subform on the CategoryID.
The following is the original code where when a child not is clicked only pops up a "linked" msgbox. I need to modify the part of the code on the Select Case "C" in red:
Code: '---------------------------- Sub DisplayForm(i As Integer) '---------------------------- ' for this Treeview I do not want a double-click on a parent node ' to open the applicable Category form, but pressing the shift key ' should open the marriage form applicable to the parent node. Shift ' or double-click on a child node should open the applicable ' offence form.
Dim strKey As String Dim strTag As String Dim strFilter As String
please see attachment. I created a small database to help explain my issue.
When I click on the check box in box 1(train), the text box turns blue...great...and even better the other records stay clear when I scroll down, which is what I want to happen. But when I scroll back up, from dog to train, the blue in the train box has gone- not what I want! I would like the blue to stay in every box that I click on. Any ideas?
I have a check box on a form,that when ticked ,Iwant it to lock that check box (basically i dont want that info altered after this time) I know its something to do with the property but cant get it to lock the check box).
I agree completely with everyone when it comes to not using lookup fields in tables.But does that extend to Display Control of yes/no tables? What are the problems with setting the Display Control to "Check Box"?
In a current form I want to display a checkbox that can be checked or unchecked. Based on if the box is checked or not, a value will be placed in a field when the record gets updated or created...
I have created a check box but when I click it, I am unable to uncheck it, Im pretty confident I can do the later part in coding it into the database... its just having the free ability to check it or not!
I then have a crosstab query that counts the different "AggType" like this. (This data is output to a report as both data and a chart)
Verbal, Physical, Threat 2, 1, 1
This all works great IF the date range is large enough that all 3 AggType fields are included. BUT, I my date range was from 01/05/2006 to 31/05/2006, I would only have 1 record (23, Agressive, 14/05/2006, Threat ) so the crosstab would result in ONE field only. (Threat)
The problem is that my report is looking for 3 fields (Verbal, physical and Threat)
How can I stop the report from giving an error if fields are missing from the crosstab result?
I have built several combo boxes in other DB's but haven't had this happen before. I am adapting a template DB to work for me. The form is continuous and I added a field [CategoryID], I want the [ProductID] to filter based on CategoryID choice. Pretty straight forward and it works, but the [ProductID] field will not hold the text value. It's a number field to hold the ID value, and bound column is 1(Select query is ID,ProductName,StandardCost) with ID and StandardCost column widths set to 0cm. I can choose CategoryID, the ProductID combo filters correctly, then when I proceed to the next record, the ProductID goes blank.
Is there a way to configure Access so SQL View saves white space changes to a query? By white space changes I mean tabs, spaces and carriage returns added to make the query more readable in SQL view.
For instance:
When I'm editing a complex query in Access, I space it out nicely like:
or something similar, with spaces between fields, parenthesis, and carriage returns or tabs in between major blocks of logic to increase readability. It's simplified above but I hope you get the point.
When I save it and return to SQL View later, Access compacts the query to:
SELECT((field1*field2)+(field2*field3))/field4 AS [Weighted Avg] FROM table1,table2,table3 WHERE table1.field='xxx'
The above example isn't so bad, but with multipe selects, joins and mathematical calculations using parenthesis, it becomes really unreadable after Access "compacts" it.
I have a listbox on a form with several fields, 3 of which are currency fields.When I filter the listbox using afterupdate from a combobox on the same form, the listbox loses the currency format on the fields.
Hi Ive been searching for answers need assist. I have a multi tab form with multiple sub forms and control buttons. One of the buttons calls a report to come into preview mode.
the problem is when I close the report the multitab form loses its max size. I have tried docmd.maximize on the on open, on got focus of the form and I have tried the docmd.restore as well with no luck.

Still fighting to understand a darn thing about treeviews. What I was hoping to do was create a kind of knowledge base that I could integrate into a larger database I'm using. I wanted for each entry to have a category, short description and then longer details. Then for the treeview to display each item grouped by category. So in the treeview, you'd click on Category 1 and it would display every knoweldge base item that is in category 1. Click on any of those nodes and have the subform change to display that knowledge base item.
I have NO idea how to design the treeview to do this. But have laid out the database to do just about everything else.
I've been trying to use TreeView control to display my computer's directories and folders just like Windows Explorer does.
Thanks to Popeye for reposting all the Treeview samples (samples posted before the site was hacked). Most or all of these samples, TreeView is used to display data out of tables. Mr. Ghuson posted a great example for browsing directory but it pops up a separate windows for browsing.
Now I'd like to somehow combine the two into one; browsing thru directories and folders using TreeView Control. Yes that I can browse and save all paths and directories to different tables and add them to the TreeView control but I'm trying to stay away from saving data to tables first.
Can this be accomplished? Can Windows Explorer be somehow embeded on an Access form or called? Any ideas, experts out there?
I have a treeview control which is based on a table.
For some reason it won't fill properly, it doesn't add the nodes under the correct parent. If someone could look at the attached file and help me out I'd appreciate it.
This is the first time I've tried to work with a treeview control and it's very challenging. I've developed the branch building code in the form's module to a point where I'm confused on how to proceed. I've attached the database and a "readme" file to this posting. I hope someone can help me.
I need a help/pointer converting this cascading list boxes into treeview control. Please help. All the data I need to construct a treeview is already at category_info table, but unable to show it attrib_cde (parent), Stage (child of parent), and ID (child of Stage). Any help or a quick example is highly appreciated.
I'm venturing into the abyss of treeviews and have read many threads on this subject. I have two questions to ask regarding the attached sample db, if anyone can help me please.
1) How can I adapt the existing code and create subnodes (or sub child nodes). For example, how can I create a sub-node of OPEN FORM2? 2) What is the syntax for an ONCLICK event, i.e. by clicking on OPEN FORM2 I want it to open FORM2?
I'm really new at VB. But I'm learning. I'm also learning to work around access too. What I'm trying to do is have a Form with a TreeViewCtl that acts as a menu for other forms. I'd like to have the TreeViewCtl open those forms in a subform so there is always just one form open at all times. This way my "clients" don't get lost in the forms. Believe me, they get lost easily...
I already posted a question like this here: http://www.access-programmers.co.uk/forums/showthread.php?t=80756 But I'm not sure if this is a VB question (TreeViewCtl) or a Forums question... A sample of what I'm trying to do is available at the link. My TreeViewCtl works fine, but the forms open in seperate forms. Sorry for the dbl-post.
Does anyone have any ideas? I've been searching google for 2 weeks without any answers.
I'm trying to create a form that is reading filenames from a certain folder on my computer. The filenames have some prefixes - 'tu' , 'tc' , 'bf' , 'tf' and 'act'. each filename that is read is being displayed (without it's prefix) in a list and has another attribute (type) that the prefix is inserted into it.
Does someone know how to start this kind of application ?
