I'm using DataSet ReadXML() method to load XML files of records different tables, and all are working fine. But, I would like to have the exceptional handling that in case there're records in XML files got problem, e.g. invalid data format or exceed column width and etc, it will skip those records and continue loading remaining XML records into DataSet.
View 2 RepliesI have a 'For Each' loop that contains some items I don't want to analyse. Now I use a GoTo command to 'skip' an item. But this is not very elegant and (knowing .NET) there is probably a way to skip to the next item without using GoTo.

following is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.

View 3 RepliesI have a collection of locations for a sales person, allowing them to send an item to multiple locations. I want to start reading at index 1 since I am using a collection. I saw an example where you can say something like "+ 1" (e.g. myitem.SelectedIndex + 1) to skip the first record. How can I skip the first record for the following:
Public ReadOnly Property Customer() As ICustomer
Get
Return CType(Me.CustomerList.Item(Me.CustomerNumSelected), ICustomer)
End Get
End Property
I tried to say Return CType(Me.CustomerList.Item(Me.CustomerNumSelected + 1), ICustomer) but it returns an error saying "string cannot be converted to a double". without the + 1 in there, I get an error that says "collection index must be in range 1 to size of collection".

When the program is launched it immediately says folder access denied. i am wondering if there is a way to skip that folder and go to the next one. I have tried try and if statement but they don't seem to work. Here is the code so far:
For Each file In My.Computer.FileSystem.GetFiles("c:", FileIO.SearchOption.SearchTopLevelOnly, "test.*")
ListBox1.Items.Add(file)
Next
My code so far:
If newpound.Text.Length = 0 Then Else
Dim newpound1 As Integer
Static savedpound1 As Integer
savedpound.Text = newpound.Text
newpound1 = newpound1
savedpound1 = savedpound1
newpound.Clear()
End If
What can I put between Then and Else to ignore Dim newpound>newpound.clear?
If the text box is empty and it moves on to the next one.
Bin working on this for like 2 hours now and still don't get it proper to work.
I think its a small thing but I can't see it.
I got a project with 2 forms. Form1 is a register me form, so it shows a form with lets say a OK button. if you click the OK button it writes the figure lets say 989 in the register.
After that is done it opens Form2 and you can do your thing.
That part works.
after you click OK it shows form2 and hides form1.

I have a table with several columns that allow NULLs. How would I go about writing a SQL Query that will allow me to skip that column in an update if the value is "empty". Should I use a boolean flag letting the query know to update that value? I do something similar in a SELECT like this SELECT * FROM table WHERE (@boolFlag = 1 OR col1 = @col1Val)But trying to do that for an update has proven to be an exercise in futility. Ideally I'd be able to say skip this value if true, otherwise update over my 20ish columns. Right now I can't pass in DBNull.Value, so instead I'm being forced to insert "" which is converted into whitespace (for instance, my nvarchar(50) has 50 spaces).I'm using a SQL Server DB/Table and a DataSet in VB.NET, constructing my queries in VS2k8 if that matters.
