I am using this to load settings files, but if a piece is missing, then the whole thing fails. What can I use to load each node individually instead?

View 8 RepliesVS 2010 : Writing Serialized Object To File?
Apr 6, 2010I have a class like this:
<Serializable()> Public Class GOODownloadFile
Private aID As String
Private aDownloadLink As String
[code]....
Now when I create an object like this
Dim f As New GOODownloadFile("http:\download.com1.exe", "c:Down", "c:Down")
downloader.AddDownloadFile(f)
downloader.WriteInfoFile("C:1.txt")
All the values given are correctly saved in the file 1.txt But when I change the download file info afterwatds, like this:
Dim f As New GOODownloadFile("http:\download.com1.exe", "c:Down", "c:Down")
downloader.AddDownloadFile(f)
downloader.WriteInfoFile("C:1.txt")
[code]....
the new value (123456) is not saved. Hence, only the values provided BEFORE the AddDownload are saved, the rest aren't.
I've check my code 100times, and I'm sure everything is fine. I think it may be because of the send-by-value. When I change the values afterwards, the orginal object isn't used.
VS 2010 Properties Set During Design-time Are Not Serialized To Designer File
Aug 22, 2011I am creating a UserControl with rich design-time support that should eventually look like the Options window in Visual Studio (or many other applications). Basically a split container, to the left is a TreeView with 'option categories', and each node in the treeview corresponds to a 'panel' to the right with certain options.
Just for terminology, the nodes in the TreeView are OptionsNode objects, the panels (containing the controls that determine the options) are OptionsPanel controls. My UserControl itself is called OptionsView and is the control that contains the treeview as well as a panel that contains the OptionsPanels.
I have some experience in design-time coding, and I have gotten pretty far. The OptionsView control contains a property Panels that returns the ControlCollection of the right side of the split container. The user can add/remove OptionsPanels via this property (and automatically an OptionsNode is created). The property uses a custom CollectionEditor that tells the designer to create instances of type OptionsPanel (instead of just Control which is the usual collection type of ControlCollection). Furthermore, in the CreateInstance method I use the DesignerHost object and its CreateComponent method to create the panels, instead of just creating New OptionsPanel objects. This way the OptionsPanel created is selectable and editable (via property grid) during design-time:
vb.net
Protected Overrides Function CreateInstance(ByVal itemType As System.Type) As Object
If itemType Is GetType(OptionsPanel) Then

VS 2010 - My.Settings - Can't Find File Which Reflects Changes To User Settings
Apr 15, 20111. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...

VS 2008 Settings Are Read From App.config Instead Of Settings-file
Oct 30, 2009I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.
View 4 RepliesChecking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

Loop Through Treeview Nodes To Delete Certain Nodes?
Dec 16, 2010I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:

I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.
Searching One XML File For A Set Of Nodes And Inserting Them Into Another XML File?

Replacing Nodes In A Xml File?
Sep 5, 2011I decided to use XML to handle some of my configuration chores. My XML file looks something like this:
<catagories>
<catagory path= "C: empwyoming" name="Wyoming">
<URL Filename="Picture1.jpg">http://www.domain1.com/pic.jpg</URL>
<URL Filename="Picture2.jpg">http://www.domain2.com/pic.jpg</URL>
[code]....
I'm wanting to manage this list in my program. Currently, I have written code to read the catagories into a combo box, and once a catagory is chosen, I can read the children URL nodes into a listview. I want to allow editing and re-arranging of the URLs in the listview, and I'll have no problems with that. So my question is, what is the best way to dump the listview back to the xml file? You should consider the contents of the listview as a replacement for ALL of the existing children in the XML file.

C# - .NET 3/4 Permits Events To Be Binary De/Serialized?
Feb 25, 2010In .NET (at least <=2) there's a problem serializing objects that raise events when those events are handled by a non-serializable object (like a Windows Form).Because of the way VB.NET implements events, when you serialize an object, its events get serialized too (because events are actually implemented using hidden multicast delegate fields). A side effect of this is that any object which handles events raised by the object being serialized will be considered part of the object graph and will be serialized too.
Some workarounds could be found, implementing custom serialization or using delegates instead of events:[URL]..

View 6 RepliesCreating Serialized Picture Boxes
Dec 27, 2010I'm building a simple game which involves many pictureboxes with which the player may collide. For instance, I'd have a hundred bricks spread throughout the level. In an old version of pacman I built in VB6 (and upgraded to .net), I implemented this like so: [Code]
As I understood, the brick(I) array exists thanks to the naming of the bricks, which ranges from _brick_0 to _brick_217 (as nowhere in the project a brick array is declared implicitly, at least not that I could find). I'd like to do the same in my current project, but even when I duplicate an existing brick it automatically renames it to "PictureBox123" instead of _ExistingName_NextID.
I saw a method of declaring a picturebox array and adding the bricks one by one, but since I have so many pictures this would best be avoided (especially due to the fact that not all pictures are bricks, so I cant just loop through every picture in the form). In short, my question is: How do I duplicate pictureboxes so that they'd be serialized in a way vb.net would interpret as a picturebox array? As you can see, i'm a really newbie to vb.net and wf in general, just started studying wf a couple days ago for my B.Sc and even that was accomplished with c#.

Format Property Serialized Using Xml.serialization?
Sep 26, 2011I have created a class from an xml schema (that I do not own and cannot change) using xsd.exe. Using this class, I am deserializing to bring the data in to an object collection to consume. There are times when I want to take objects in memory and pass them to the class created by xsd.exe using a constructor I built to generate a serialiable object collection.
I cannot figure out how to format some objects correctly Example: In the xml file, there are certain simple types that are floats that come in with 6 digits of precision. When I write them out, they have 7 digits of precision. Anorther example is integers with leading zeros in the xml file. They come in as 4 digits regardless of leading zeros, but I can't find a suitable way using serialization to output them (other than to change the property to a string datatype.[code]...
