For Loop Skipping Rows In DataSet?
Jul 26, 2010My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If

Loop Through All Selected ListView Items
Oct 7, 2011I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.
For i As Integer = 0 To ListView1.Items.Count - 1
Dim ftp As New FTPclient(host.Text, username.Text, password.Text)
ftp.FtpDelete(ListView1.SelectedItems(i).Text)
Next
Some info:
The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.

View 5 RepliesVS 2005 Erasing Items In A Collection Using A Loop?
Jul 1, 2009I often use a for/next loop to cycle through a collection to find a particular member of that collection based on some criteria. This works fine in every case except one: when I want to then erase the very member of the collection I just found. For example, if I wanted to give the heave-ho to every obect in a collection class that has a member veriable Color equal to Red:
[Code]...
The problem is once the collection class member is erased it makes to loop invalid because taking out the member reduces the total count of the collection in the middle of the loop. Eventually I get a "Index is out of range" error.This circumstance has bothered me every so often; I bet more experienced programmers have a different type of loop system that works better than this when you want to erase a collection member.
Loop Through DetailsView To Hide Dynamic BulletedList Items?
Feb 2, 2012I need to be able to hide 2 options that are displayed from my dynamic bulletedlist (which is built inside of a DetailsView). Every time I try writing a loop through the BulletedList, I get an error saying that it is not a collection type, so I thought I could loop through the DetailsView to find the items I want to hide.
I can't change the SQL because this particular bulleted list gets used on 2 different pages, it's just that on one, I only need to show 2 of the 4 items that are associated with the ID.[code]...

VB.NET

The exclusion list works great, but it duplicates each item in the ListView several times. How many depends on how many items that it excludes.
I understand why it's happening, but I can't figure out a way around it. I have to loop through the items in the ArrayList so that I can compare them to the other items.

Skipping The Last Number In A Query?
Jun 25, 2010This is my frist post on the forum So I hope I am giving enough info, If not let me know if there isanything I missed.I have currently completed a project where I do a Query in SQL Server 2000 in VB 2010 and produce reports for each Tax id. When I Debug the program it finds the number and processes the reports, when I just let it run as an executable it does not pick up or find the number.
This number happens to be the last number coming back from the query and it processess in a loop while Not filename.EOF it goes thru 4 seperate routines and then loops back to get the next taxid. I did not put any routines to sleep and I am thinking maybe the application is just stepping on itself, could this be right? Thecreatereport path does a sql execute for the appropriated Table against the TaxID an the current Cycledate, then produces the report va CR2010(beta) and exports it as a pdf file to a directory on the shared sever.

SQL Insert Skipping Some Records
Oct 8, 2009[Code]...
With the code above, I'm trying to create and insert records into a MySQL database. The issue here is that not all records are inserted. If the XML document I'm reading from has 80 records, only 40, or 66, or some other number get put into the database. I'm guessing this is because the code is trying to insert the records faster than the database can handle them? What would the correct way to make sure the record is in the database before moving on to the next one?
