i was told i need to use invoke to marshal to fix this exception : Control 'TxtFolderActivity' accessed from a thread other than the thread it was created on. i cant seem to figure it out. here is the snippet of code where i need the invoke. Private Sub logchange(ByVal source As Object, ByVal e As _ System.IO.FileSystemEventArgs) If e.ChangeType = IO.WatcherChangeTypes.Changed Then TxtFolderActivity.Text &= "File " & e.FullPath & _ " has been modified" & vbCrLf End If If e.ChangeType = IO.WatcherChangeTypes.Created Then TxtFolderActivity.Text &= "File " & e.FullPath & _ " has been created" & vbCrLf End If If e.ChangeType = IO.WatcherChangeTypes.Deleted Then TxtFolderActivity.Text &= "File " & e.FullPath & _ " has been deleted" & vbCrLf End If End Sub Makniteasy

I have a problem with data in a text file. my data is a row in a data grid, but when i write my data to the file it writes it like this: 101405johnsmith050605. when it writes the data row like this, how do i get certain things to certain places? like 10 would be the record number and john smith would be the payee and 050605 would be the date. since it is not writen like this I cannot get john smith to textbox2 on form2 and i cant specify that i want 050605 to textbox3 form 2. how do i write the datarow so i can have certain pieces of it go to certain textboxes?

I have a loop for a datagrid that shows all the amount rows added together in the caption.text of the datagrid. now i am going to change the loop because i dont need to add the rows, i need to subtract them. i know how to do that, but my question is that i have a textbox(textbox6) for which the user will need to enter a balance to show in the caption.text before the loop can subtract anything. any tips will be greatly appreciated. this is what i have. Dim t6 As Object t6 = TextBox6.Text For Each t As String In TextBox6.Text Amount += t Next Me.DataGrid1.CaptionText = "Current balance $" & t6.ToString() it is acting wierd. if i input 7 in the textbox then the data grid recieves only an addition of 1. if i input 9 it gets an addition of 4.why Makniteasy

thanks for the help. The help you provided was exactly what i needed. i was trying to get the amount column of a datagrid, for which the user enters the amount they paid, to show in the datagrid caption text when entered. I am going to post another question so that you wont have to keep to returning this one. thanks Makniteasy

thanks that fixed that problem but now i have another: Dim Amount As Double = 0 For Each dr As DataRow In ds.Tables(0).Rows dr = dr + ds.Tables(0).item("Amount") Next Me.Text = ("My Balance $") & ("Amount").ToString now this is underlined. i think im lost in the loop now.any more suggestions? Makniteasy

i need to loop some rows in my datagrid to add them and show the total. i am using: Dim dr As DataRow Dim Amount As Double = 0 For Each dr As System.Data.DataRow _ In ds.Tables(0) dr = dr + ds.Tables(0).Rows.Item("Amount") Next Me.Text = ("My Balance $") & Amount.ToString everything is fine except the underlined part. it keeps saying that it is a member of system.data.datatable which is not a collection type. does anyone know what i am doing wrong? Makniteasy

thanx

i have create datasets before and now when i apply: Imports system.data it says this namespace cannot be found. why is that?

what type of file is your data in? if it is xml then you can try: Dim DS As DataSet DS.ReadXml("C:\the file path")
