Algorith To Move Through Arraysq
May 31, 2012I have the frets on one direction and the strings on another. Now let's imagine a 6x13 matrix (considering open strings and up to the 12th fret) will locate each note. So a NoteLocationMatrix(i,j) will locate each note. Now lets imagine i have a one dimension array for all the 12 notes (C, C#, D....) in which Notes(k) represents a note. Now lets assume each NoteLocationMatrix(i,j) has a property Notes, so

View 2 RepliesTree.SelectedNode = Tree.Nodes(0) 'returns Error With System Reserved Partition?
Jun 12, 2011I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.
View 3 RepliesNeed To Change One Combo Box (of Many) To Order Items In Descending Order
Nov 1, 2009I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesRe Order Column Order In A Data Bound DataGridView?
Apr 17, 2010I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
VS 2010 : Access ORDER BY To Get DESCENDING Order

Drag/Drop Within A Tree And Drag/drop From Tree To Textbox
Oct 20, 2010drag and drop nodes within the same tree (not between trees) when users drag and drop nodes within the tree, give them the option to move the original node to a new location within the tree OR to just copy the original node in a new location (seems complex but I have a month to figure this out). change the system default blue highlight for selected nodes to another color change the system default cursors for invalid and valid drops (instead of the circle with slash indicating invalid target, i want a red minus) and (instead of the little plus sign with little box indicating a valid target, i want just a big green plus sign) add a red insert line to indicate where the node would be dropped within a tree also drag and drop the text of a node from the tree to a textbox add a "folder" image next to parent nodes and a "document" image next to children nodes
I have looked through the internet but I am having difficulty sorting through all the information available (I see a lot of information for Visual Basic 5 and 6, and those codes don't work for me in visual studio 2008). I can email anyone my code I have so far.

View 1 RepliesPopulate A Tree From A Database?
May 17, 2010I am trying to learn how to populate a tree from a database, I did this same thing back in Vb6 and am trying to learnhow to do it in VB.Net, but I am having trouble with the code. From looking on the web I have piced this together, but I think it may be far off. It just jumps out put leaving the tree blank; and it gives no error message. I put in a try error catch and it cannot convert the data to a double, but even if I take this out it does not work. It is stuck at the line with: dr("CustomerID") <> hID I was using this to check for a parent node, I can take it out, but it still does not work; I am afraid that I am be way off here. I am using the Nothwind database.

View 1 Replies.net - Translate This Code Into An Expression Tree?
Feb 12, 2010I have a hashing method whose operations depend on input to the function. Profiling the program has shown that too much time is spent evaluating this hash method. I want to try changing it into an expression tree, so the inner loop checks can be done once.
Here is a simplified version of the function (I undid some obvious optimizations for the example, and took out any input validation):
Private Function Checksum(ByVal inputValues As IEnumerable(Of UInt32),
ByVal declarations As IEnumerable(Of String),
ByVal statements As IEnumerable(Of String)) As UInt32
Dim variables = New Dictionary(Of Char, UInt32)
[code]....
I want to create a function which takes the declarations and statements and outputs a specialized expression tree representing a function which takes an IEnumerable of UInt32 and returns a UInt32.Follow-Up:I succeeded, and the speed-up was ridiculous (an order of magnitude). The main things I had to learn where:Use Expression.Lambda and Expression.Compile to get a delegate you can actually use.The Expression.Block factory method has a 'variables' parameter you (essentially) use to declare locals.Expression.lambda has 'parameters'.If you call Expression.Parameter twice, you're dealing with two different variables (even if their name is the same)! Store the result for later usage. Same for labels, etc.The result of a BlockExpression is the last expression in the block.

Jan 17, 2012I need to compare two tree-structured reports and show comparison results in a datagridview in vb.net. I think using tree structure should be efficient. But note that I DO NOT use a tree view to display results (I found a lot of help in tree view though). All I want to do is to construct two trees, and then search the trees and compare. I do not know how to write this in vb.net.
