I am trying to solve a mystery in VB 2010. I tried to look up in many places for the code or an example but every thing I have found was outdated. So, all I need is a code which will produce a file list of my ftp server/folder which will be transfered to ListBox object. Here is another thing. Everything I need in the ListBox is only a file name and its extention:[code]

I could sure use some help. In a form of a push in the right direction. I am tryig to remove all multiple tcode (stock name) and add (if tcode is "B" add the shares and if tcode is "S" subtract the shares) them together in just one line of text in a label and if the shares add up to 0 after subtracting the shares bought and sold than don't add it to the the label.The following are my total trasactions for id# 111
tid , tcode , ttype , tshares , tprice
111 frd B 500 $300.00
111 frd S 100 $320.00 (500- 100 = 400)
111 frd S 100 $250.00 (400 - 100 = 300)
When I hit the summary button it should display
tid , tcode , tshares , tprice
111 frd 300 $275.00
I know I am only working with total shares(tshares), Im not sure how to put it so it will read only one line of the frd stock. I think I have to subtract each stock as it goes in a loop but I am not sure how to apply it to my code. I already used a loop to read each line, I think I need a for loop somewhere. I tried puting it in different locations but it will not work..here my code.
Private Sub btnSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSummary.Click
Dim tid As String = ""

This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

I have a slightly odd problem that I think is most likely due to an act of foolishness on my part, but for the life of me I (and other members of my team) can't see it.I have an object that contains a generic list property which I would like to sort. I have written a comparer class to do this for me and I am calling it in the following way:baseObject.ListOfThings.Sort(new ThingComparer()I have debugged into my compare function and it is returning the right values.However After the sort call, the list remains unchanged. Have I missed something obvious, or is there something else I need to do.EDIT: Yes I was being a fool, and the property returning a list was recreating it from scratch each time it was accessed
View 4 RepliesI am trying to create a clone function to create a deep copy of an object. I have a very simple class with one property, a List of another custom class. Everything I try keeps ending up with the cloned object being a pointer to the original. I was able to do this in C#, but when I translated the code to VB2010 the copy does not work. My simple class is below.

I have started researching Reactive extensions and I would like to know how to do the following (ill try and keep it simple):

2) when an item is added to the said list, do something with it...
Guess im just kinda stuck where to start :/
I want to create a extension class for the List type so users can do [code]I've it defined as Type and also tried object but neither are accessible when I have a list of strings.If I set it to be string it then appears..But I want something that is more generic and will work with all lists. How do I need to define it?
View 1 RepliesI'm writing a program that reads a directory of xml files (not well-formed), parses the xml, and dumps the data into an Excel Workbook.The file contents are similar in that they have many common xml nodes/attributes.Some files have additional nodes/attributes.The xml in these files represent configuration settings for a Web Application, one file per user.The expected output is a worksheet with a column for each node/attribute combination and a row of node/attribute values for each user.I'm just about finished with the program, but I've run into a bit of a snag.As the final step in the process, I need to loop through a generic list of array objects (that represent a user row) and send the array elements to Excel.I don't know the correct syntax to get the array objects out of the list and have been unable to find sample code specific to generic lists of array objects.[code]
View 3 Repliesso I have a generic list in a console application. Dim Channels as New List(Of Chatroom) Chatroom is a structure. But I have multiple classes, threads, and timers looping through this list, sometimes at the same time, but it always seems to raise errors because the number of items in the list gets changed while one of the other classes/threads/timers are looping through also. Is there any way to allow only one to manipulate it at a time?
View 8 RepliesI have a custom list that inherits Generic.List and it has a method for deselecting all of the members named DeselectAll It has looked like this for a few weeks and has worked fine.
Public Sub DeselectAll()
MyBase.ForEach(Function(p As Publipostable) p.ModeEnvoiChoisi = Nothing)
End Sub
Today, it stopped working ?!? I reverted to an earlier version using delegates and that works fine...
Public Sub DeselectAll()
MyBase.ForEach(AddressOf DeselectModeEnvoi)
End Sub
[code]....
Edit: Stopped Working meaning it no longer sets the property p.ModeEnvoiChoisi to Nothing on each item in the list. The DeselectAll method gets called, but all the items retain their previous values...
I am using VB.NET and I can't compare the radio button lists selectedItem.Value to a string, it doesn't work...here is the code: (I have also tried selectedValue it does not work either)

Why won't it evaluate that rblOne.SelectedItem.Value = "No" !?!?!? I tried rblOne.SelectedValue, that doesn't work, AND I added .ToString to both, which did not help, I even tried it w/ "No".ToString...this doesn't make any sense.
I load a list from a database like the example below. The class has more properties that the database table holds so when I load the list from the DB, there are Null values for certain properties of each item in the list. When I try List = List.Distinct.ToList, it never works (when null values are present).

I have the following code,
PB.ForEach(Function(x) x.Cost = GetPartCost(x.PartNumber, x.Units, x.Cost, FB))
Return PB.Sum(Function(x) (x.Cost * x.Qty))
However it always returns 0. I've checked and the GetPartCost function executes and returns a non-zero number but the list item cost properties are never updated.The property is just a simple property,
Public Property Cost() As Double
Get
Return _Cost[code]....
If I set a breakpoint in the Set of the property, it never gets hit.

I am trying to call a batch file from my program. It opens the file but the file doesn't work. This requires a little knowledge of java.
method one:
Code:
Dim odlg As New OpenFileDialog
odlg.InitialDirectory = path
odlg.Filter = ("Batch Files (*bat)|")
[code]....
Both of these make the batch file appear but somehow it isn't opened correctly or something. The two batch files are in the resources of my project. They get copied to a folder and that directory is named "path" which appears in the code above. Then I try to call the file from that folder with the directory being called "pathComp" which also appears in the code above. This batch file is meant to compile the java files created in a folder by the program by using the command "javac". Now when I run the program and get to this point and the batch window opens the cmd window says this:
Quote:
javac: invalid flag: *java
Usage: javac <options> <source files> use -help for a list of possible options
[code]....
It doesn't compile the files, however when I run the batch file independently of the program it works fine. I really need some help on this one. If you need it here is the code for the batch file that is called:

I just saw in some wordpress plugins, there are auto tag plugin, auto RSS fetch, just you install the plugin and it keep working for ever without calling it.What i want to do is to put a dll file inside my Images folder and it will monitor the uploaded files and edit them based on some options, i want this dll to work automatically just when uploaded in the right folder, and keep running forever This can be done? If no, there is another options to do so? "i know that i can use a windows service or startup applciation, i mean other options" UPDATE: i want any other options, because the server may be shared so have no access on its windows to make a service or a start up.

How can I get the file NAME from the OpenFileDialog and make the Browse folder dialog to have the File NAME at the end of the folder destination?
1. I press "Browse for File"
2. I press "Browse for Folder"
3. After the directory for Browse for folder is shown, it will also include the file name taken from "Browse for file". I dont want it to replace the destination, but to add the File NAME to the folder destination.For example
"Browse for File" gives me the destination, C:Documents and SettingsOwnerDesktopFile.txt
"Browse for Folder" gives me C:Documents and SettingsOwnerDesktopNew Folder (3)
I want the File.txt text COPIED from "Browse for File" and PASTED on to the Destination of "Browse for Folder"
