Create XML, Save It, Open Later And Load Into TreeView Control
Sep 28, 2009
I need to create an XML doc that I can call up and populate a treeview with. Can someone show me that basics on doing this. A simple example will suffice. Note I am not using XML-speak for any of this description. Assume I have some unknown number of Types (Parent Nodes). Each Type has a possible of Three Groups (children to Type nodes). Each Group has an unknown number of randomly names Cases (children to Type nodes). I want to create this XML file, save to a directory and the open again later to load into a treeView control.
Type1
Group 1
XYZ Case

This is one of those problems where there just doesn't seem to be anything of use on Google.Does anyone have any code snippets of how to achieve this? This thread: url...links to a solution but experts exchange has been a paid for service for a while now.Ideally, the solution needs to be able to handle any number of parent/child nodes.

I have multiple controls on my form. Text boxes, radio buttons, check boxes, etc. Is there a way to move through every control on the form and save it's value, status ? Like whether the radio button is checked, or not. The value of the text box, and save them all to a text file. Then, reload the values saved in the text file in the same sequence. Without doing all this one line at a time.

I have looked everywhere for some info on how to code save and open buttons. In my program, there are textboxes and labels that will have info entered into them by the user. I need to be able save whatever is in the labels and textboxes. Then, I need to be able to open the file and have all values in the labels and textboxes to be restored to wherever they were. I want to be able to save and open just like in excel, word, and whatnot with a file that is saved onto the computer.

I am looking for a way to save and load the values of all my controls present in my form.My form has around 100 controls spread over 7 tabs. The controls include (Multiline) TextBoxes (Strings), NumericUpDowns (Integers, Decimals) and Checkboxes (Booleans). If the user clicks the save button a "Save File" dialog should appear allowing the user to specify the directory and the filename of the save file.All the values of the controls should then be written to that file.If the user clicks the load button an "Open File" should appear where the user can pick a previously saved save file. All the controls should then adopt the values found in the save file.I have implemented Application Settings in my form, and now when I click save, it saves the control values through My.Settings.Save(). If I click load it loads them.However, my project requires that multiple save files can be made to reflect multiple configurations. As I understand Application Settings only allow for a single .config file in the Application Data folder.So how can I code a save/load routine to save/load different configurations?

I am using webbrwoser control to open Word document for editing on winform using vb.net. (vs 2005). Now once user edit the word document, I want to forcefully save that edited document to my document when user directly close win form or user will try to EXIT. Unfortunately, word doc which open on webbrowser control if it is edited and when winfrom is being closed it won't ask us to save where as independent word document aske to save changes. I tried to call method "ShowSaveasDialog()" of webbrowser control on winform close event it did not fire up.

I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.

What is the best to load a treeview from a database where it goes 4 deep
Parent
child
child
[Code]....
How would that look in a database? and then how would you load the tree. I can load everything up to the grandchild, but as soon as I load the great grandchild I start having issues. So I am thinking it is the way they are in the database.

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 am wanting to find out how to use the Win32 hooks to allow me to add extra save locations to the save and open dialog box so as to allow as an option for files to be saved directly to a database rather than a file system.I have tried looking online but can't find anything remotely usable for this, the only data on hooks that I can find involves Window operation hooks, mouse, leyboard, and shell hooks, nothing to do with files.

I've placed a treeview on my form and when debugging everything works as planned. However, when I publish the application and run it on another machine, I get a null reference exception. This form is an MDIchild and another form in the same child collection loads its TreeView data with no problem.Here's my code, MajorCategories(), MiddleCategories(), MinorCategories() are all arrays of Structures filled in an outside subroutine.

I've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)

has anyone come up with a with a way to save a treeview without using a BLOB, I have some items that are 8-10 levels deep on it. if I could export it to xml and back again that would be ok, I need to store its info in a databse cell set to memo. but I need to inport the text from the cell and insert it back into the treeview, then when I save i need to save the data back into that cell.
