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.
Private Sub DisplayTreeview()
Try
tv.Nodes.Clear()
Dim i, j As Integer, ds1 As DataSet
S = "select * from Product where PdtRoot=''"

From a TreeView, I get this XML serialized:
<?xml version="1.0" encoding="utf-16"?>
<node text="<span id='c6f5ab9e-d08f-448a-9143-02d174317c07' oncontextmenu="
SetContextMenu(this.id, event);return false;"
>Zürich</span>" value="c6f5ab9e-d08f-448a-9143-02d174317c07" navigateurl="" populateondemand="False" showcheckbox="false" checked="False" expanded="True" selected="False">

I was making a treeview favorites for my browser and got this code, however, nothing happens on startup, like the treeview stays emty
Heres the code for the Load handler
If System.IO.File.Exists(FavFile) Then
Dim xdoc As New Xml.XmlDocument

the exact same code works for the orginal project, and I have the same xml document in the same subfolders for my project
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

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.
View 3 RepliesI'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.
Private Sub CategoryMaintenance_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
RedrawTree()

I have a problems with my application..
1. collapse and expand treeview when i click plus sign (+) on treeview, treeview didn't expand subfolder but when i click image, treeview expand it.
2. showing path that i check on treeview when i check the treeview then i'm click the button, then return path that i check
This is my code..
I want to specify which folders the treeview can access or not access(which ever is easiest).The following what I have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
Dim newNode As TreeNode
[code]....
The question says it all, I can connect/Open a Access DB and I can setup a Treeview but how can I bind them together?
View 1 Replies1. How do you load the same form?
2. This form has the datagridview, textbox, combobox, how do you save the values with tables?(The different persons will use this same blank form to manage the jobs)
I have 1 tabcontrol with 2 tabpages, each tabpage with 1 datagridview (different tables for each), I load these 2 databases on the form load:
Me.AnndepTableAdapter.Fill(Me.HonorDataSet2.anndep)
Me.SysdepTableAdapter.Fill(Me.HonorDataSet.sysdep)
Dim sql1 As String
Dim con1 As New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersuserDesktophonor.mdb")
[code]....
What I am "trying" to do is to take a combo box control on my form, and load it up with data from an access db, but I dont want them to be linked so that when I change the combo box to another value it will cahnge record data. From the pics attached I have manage to load the data into the combo box, but the 2 are linked and when I try to change the combo box it creates violations in the database as its trying to change the records.

View 7 RepliesI'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

what do you think would be the best way to load a fixed length text file into ms access? this is how i would normally do it if it was comma delimitted:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & FilePath & ";HDR=NO].[" & FileName & "]"
sql.ExecuteNonQuery()
I cannot figure out how to get past this error. I have 1) Given the user "everyone" access to the entire directory that this dll is contained in 2) Deleted the dll and rebuilt the project 3) Deleted the Temporary ASP.NET files in the Windows Directory 4) Restarted IIS 5) Tried to change to a different user in IIS security including trying ASPNET. we are not using windows authentication. 6) Even copied that dll from other machines.
Here's the error. I have no clue at this point if it's code missing inside it or something else wrong with it or my setup. Other people on my team are using this dll ok. Could not load file or assembly 'Anthem' or one of its dependencies. Access is denied.

I have some questions about bitmaps and such. I am using the IDXSurfaceFactory::LoadImage Method to load an image and now I want to access its memory buffer, so I can do some direct memory manipulation and copy the content to another buffer afterwards (no BitBlit!). I managed to successfully use LoadImage, but I have no idea how to retrieve the pointer to the memory buffer and other informations. I want to basically know everything about, how and where the image is stored in the memory buffer.
Does windows always load images as BGR regardless of its original format? if not, how can I find out if the loaded image is stored as BGR or RGB. How can I find out how many bits each color has? How can I find out if the image is stored y-reversed? And if you load an indexed png for example, with one color marked as transparent, how can I find out which color is used for transparency?
I can load a generic user control just fine in my WCF service doing the following:

third one i want to save and load(with dialogs) my database from main form to child forms' datagridview.and the last one is help provider. i prepare my own .htm help file, when press F1 it opens. but i dont know how to call provider to toolstripmenuitem and help provider keep my computer's path so when i call provider another computer, the programme cant find the path.
i have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.
