Tree View Where User May Check Off Multiple Files?
Aug 24, 2009
I am a beginner so please be patient. I am trying to solve problems with existing code. We have a tree view where user may check off multiple files (tif,pdf, doc etc) for printing.When the print buttton is clicked each document should be printed. Each document must be printed in full before the next one starts. The docs are not printing in full or in order. I have attached the code for review.
Private Sub RecurseNodes(ByVal col As TreeNodeCollection)
For Each tn As TreeNode In col
If tn.Tag = "FILE" And tn.Checked Then
I am attempting to play a set of audio files continuously using a tree view. I am having troubles looping through an array to play one song after another in the selected parent node. It seems to work if I only use one song in the array but it doesn't want to actually loop through and keep playing; it goes through the loop but once the first song is over it stops. I am unsure if looping through an array in the AfterSelect sub routine is the best way of doing this,
Here is the entire Sub routine for the AfterSelect on the tree view.trvMain is the name of the entire tree view.wmpMain is the Windows Media Player COM.trvJazzHancock is the parent node for the two audio files I'm attempting to loop.
I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.
I need to require the user of this program to select two text files from any directory. I then need to display them in a List View, which I have built. File 1 needs to load into the first column and File 2 needs to load into the second. They will correspond to each other.[code]...
I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupNo) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).In every sectio/Group User must and should select minimun 2 check boxes. so If user select only one check box we need to show a pop up message as " Please select One more check box in that particular section" If User skips the message and move to next section we have to show the same message. We have to force the user to select more than one checkbox in the same section. Mainly our intention is the check boxes whatever user selected in each section/Group belongs to one Category.
Just wondering how I can populate the child node in the following coding (I am able to populate the parent node but still wondering how to list out the child nodes)
===Extra Info=== I have a class to retrieve the Category Table (CategoryID, CateogryName, ParentID) and stored it via List<T>, when I need it, I declare CateogryDAL pass it to CateogryData.
I am trying to find a quick, step by step tutorial on on to implement a tree view for my intranet that will show all the computer accounts in my domain. (this is obliviously only step number one, because once i can see them, I want to be able to query information from them.but one thing at a time right?)
Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?
I am loading the directories from my C drive into a treeview using the code below. It takes forever due to the number of folders. Is it possible to have this only populate down 1 level and then use a NodeMouseClick Event to drill down further, in the same treeView, if the user desires to do so? How would I amend this code to do this?
The following code worked with 2.0 Framework, now with NPGSQL 2.0.11 and framework 4.0, this is erroring out despite Pooling=False for the connection. The underlying logic is that add nodes to treeview; for each node added, immediately get subnodes and populate...
vb Private Sub LoadRequirements(ByVal parnode As TreeNode) Try Dim CMd1 As NpgsqlCommand CMd1 = New NpgsqlCommand
I am Developing a Application, originally i had divided a form by splitter and on left Treeview and in Right it was DatagridView. Now the requirement is to add treeview in same window. That is either Listview with Treeview in it OR DatagridView with Treeview in It.
i have a for each statement that goes thru all the nodes in the tree and checks a value BUT heres ware the issues starts I when it gets the value if depending on the value i want to move it as a child to one of the 2 parent nodes
heres the code i have
vb Dim sep As TreeNode For Each sep In TreeView1.Nodes Dim conn As MySqlConnection
I'm looking for a way to create the treeview structure in memory with a classes, so I can loop through them, like with a collection and easily load the data into a treeview, listview, datagridview or simply work with the data in the background.
There's a treenode class that I could use, but I've noticed that when I have a lot of data in the nodes, it has a lot overhead when for example serializing, because it also saves the checked state, imageindex of the nodes and things like that, which I never need. The saved file is about 10 times bigger than the actual data, which is not acceptable.
