Add A Treeview Outside Control's Boundaries?
Nov 25, 2010
I am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear

[url] How is this done? Is it a control of that form? Or is it a splashscreen or something like that?. I've tried by doing that with another form instead, but the first form will get unfocused, and i want the main form to be always focused.

I have a requirement for a new application development where I must present some information to the user for selection via drag and drop. VB offers the TreeView control which would work nice, however the user does not like the Treeview control's presentation. The user wants a control that work similar to the Mac's Finder control while in column view.
Apple's Mac Finder Control works similar to window's treeview. Finder has a nifty view capability that my users would like in some new development that is being done. The finder supports a "column" view. Similar to the treeview, it starts out in a root list. The difference being, when a user makes a selection and clicks on a node, the node doesn't expand, the sub nodes appear on the pane to the right of the list. Clicking on a sub node, will cause the pane to split again and the items within that sub node appear
to the right again.
This will happen again and again with the left pane getting narrower as the user drives deeper into the sub nodes. That is what I am trying to replicate. Obviously, once the user reaches the base list of items, we have to support drag and drop capability. Does anyone know of a control for VB.NET that work similar to the Mac's Finder control?

I'm using KeyDown to get the picturebox to move around, but I don't know how to keep the boat within the boundaries of the form. So if it hits the side of the form, I want it to just stop.
What control/procedure should I use to do this?

Today I started a little sub that would let me move a control around the form using ssigned keys but would stop at the edges of the form. I can get it to move around alright but I can't get it to stop at the edges of the form.

So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged.
I've built a UI in WPF and it works great, showing me real time updating when the hardware changes and allows me to send changes to the hardware as well by changing these properties using bindings.
What I'm hoping is that I can run the UI on a different machine than what the hardware is hooked up to without a lot of wiring up of events. Possibly even allow multiple UI's to connect to the same service and interact with this hardware.
So far I understand I'm going to need to create a WCF service. I'm trying to figure out if I'll be able to pass a reference to an object created at the service to the client leaving events intact. So that the UI will really just be bound to a remote object.
Am I moving the right direction with WCF?
Also I see tons of examples for WCF in C#, are there any good practical use examples in VB that might be along the lines of what I'm trying to do?

is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?

I have a tier application based on this video url... So far the client application only has a reference to the Business Logic (not Data Access).If i needed to tie a control such as a TreeView to list certain data fields from my table then where and how should i do that? For example i could write a For each statement to iterate through the table which returns the item from a table or i could do it in the WCF service app but how does this tie in with a control such as TreeView especially when there are no references?

I am using the following code to add all files and sub-directories to a Treeview control. The user can select a directory (using a folder browser dialog) and this code will add that directory, and all it's files and sub-directories, to the Treeview:
[Code]....
I have tried a few ways, mainly 'copying' the code from this recent codebank submission. However, I keep getting the obvious cross-thread call issue that I am adding nodes to the 'node' parameter, which is not allowed.
I am at a loss at how to do this otherwise. How can I update a Treeview like this if I have to recursively add nodes to the 'node' parameter, which is not 'available' in a separate thread?

I've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far:
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details"
What to add to these lines to simply display a checkbox next each line?

I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.
Private Sub TV_Communities_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TV_Communities.Click
For i = 0 To TV_Communities.Nodes(0).Nodes.Count - 1
If Not TV_Communities.Nodes(0).Nodes.Item(i).Checked Then
TV_Communities.Nodes.Item(0).Parent.Checked =
False
End If
Next
End Sub

I have a TreeView control in VS 2010 that I need to be able to INSERT (not add) nodes to. I have stored a unique key in the TAG for each node and know how to find the value of the tag in the tree. However, I can't figure out how to INSERT a NEW node BEFORE or AFTER the node I have found with this tag.
For example, suppose I have the following tree . . .
Item 1
... Item 2
... Item 3
... Item 4
[Code].....
I need to be able to do this for any particlular level of the tree (not just the third level where Item 6 is located). Also, Item 6 could have CHILD NODES associated with it but I need to leave those child nodes assoicated with Item 6 and INSERT Item 6.1 below (or above) Item 6 at the same level as Item 6.

Then I progressed to using the tabcontrol and multiple tabpages to group associated data for manipulation.I'm thinking the treeview control could be used to create a slick options page, however with the previous methods all the controls were drawn in design time, making it easy to edit events/properties etc.., I can only think using a treeview control on a single form that controls would need to be added programmatically/dynamically.

I am using a treeview to display projects, tasks, time entries, and the people who are working on a project. I would like to allow the user to define a custom grouping (ie. Project->Task->Time Entries or Project->Date (of time entry)->Task->TimeEntry).The relevant groups would be Project, Task, Time Entry, and Person, with some metadata from them. I want to have some modular way to allow a user to specify how they would like to display the information. Does anyone know of a good method by which this can be done? I currently have hard-coded a display which looks like this:
Project
Task
Time Entry
