Reading XML Elements In .NET?
Mar 11, 2010I have been learning VB.NET and am currently having troubles retrieving data from an XML file. I'm trying to keep the code as simple as possible as I only need to select single items from an XML file, not rows of data.
The XML file contains:
<CurrentPeakUsage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://au.com.amnet.memberutils/">
<Period>
[code]....
While the msgbox will contain the entire XML document, so it is loading correctly, I can't pull the single element value.

Change Referenced Library Files During Processing?
Mar 7, 2011I have a .NET customer framework that functions much like a Workflow. It uses reflection to get a listing of all of the processes it is capable of from a specific folder, and starts them via reflection with a known start point (all of them have a method called "Process"). Since these files are only called to do the processing and not part of the compile... is there a way for me to be able to drop in a new reference library (DLL) for one of the processes that is being updated without restarting the whole process?[code]...

View 7 RepliesPerforming Batch Processing On Selected Files
Mar 11, 2012I have created tool which performs batch processing on files that are selected. The sub routine I have defined in the code, now I want to implement a way through which I can select actions that I want to perform and then perform the actions. For example the list has multiple actions, like Open, Close, SaveAs, Resize, Color Correct etc. I should be able to select what all I want to do on each file and then perform this actions. Someone suggested me using delegates for this, but I cant use that since all my functions have different parameters. Ither option I had is to use a nested IfElse or Switch to determine which action is selected and call function according to it, but thats to heavy I think, is there any optimized a better way to do this.???

Wait For Files To Finish Populating A Directory Before Processing?
May 26, 2010I am using the FilesystemWatcher to look for files in a Directory, it does not matter what the file is. After a file appears it starts my ftp process and I end up with a bunch of 0 byte files because it processed before all the files arrived.
I would like to WaitFor... (Files_Created) to finish but dont seem to have the right syntax to get this to work properly. I have working code up until it loops. As you can see I have tried various processes to get it to work... mostly commented out. I also have imported just about everything trying to get this to work. Please ask away.

Multi-threading Processing - Processing A Large List Of Records And Inserting Them Into SQL Database One By One
Mar 18, 2011I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
2008 Array Processing And Sequential File Processing?

View 14 RepliesVB 2008 Array Processing And Sequential File Processing
May 19, 2011Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

C# - Reading Guitar Pro Files?
Feb 2, 2011I was wondering if anybody had heard of a library, preferably a .NET assembly, but Java will do as wel, that allows you to read the data in a Guitar Pro file (.gp3-gp4-gp5)I have this gigantor of a folder with about 50.000 song files, and would really love to write something that can actually archive all these files, for easier searching. And basic information like the tuning of the instruments in the song would be very useful parameters to retrieve from the file and add to the database.
I have searched the web but have yet to find anything like this, or a file definition for writing my own parser.
