There is a situation that I couldnt handle, I have 4 TextBox's and I am assigning the text to variable after loosing focus for 4 TextBox's as below;
(Variables assigned under class Form1)
Private Sub TextBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
[code]....
I have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer
intInput1 = CInt(txtInput1.Text)
If intInput1 >= 3 or <= 7 Then
messagebox.show("Input Verified")
Else
messagebox.show("Input must be a numeric value between 3 and 7")
End If
But this isn't what the assignment asks.

View 3 Repliesi have a series of CSV files that are posted to a specific web folder that I can specify in network places. Each file has same structure, lots of fields, and have consistent name schema "prefix-mm-dd-yyyy.csv". i need to use VB to process all these files, either individually or by consolidating into one file and appending to an existing table. i also need to somehow add a "download date" field to the process so i can show when the file(s) were appended. then i need to verify that it worked ok so i can then, still within VB, move the files out of the folder, such only the CSV files that have yet to be imported/appended are in the folder (so I don't have to guess about which files I have already uploaded and processed.i can figure out how to make a DO UNTIL loop, but i can't get the import statement right... nor can i figure out how to verify that the import happened in order to move (or remove) the source files.

I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value.

I can filter when I'm only checking with one textbox, but when i try to use multiple text box filters its does not work the way I want it to. I understand what is going on here but i don't know what to do to fix it. Basically I have my main form with the datagridview, there is a button on this form called filter. When the user will hit this button a small form will pop up with 5 text boxes, I want to give the user the ability to enter into any text box they wish and the datagrid view will update accordingly.The problem is when they enter into one text box it works fine, but when the try entering into a second test box the filter is only filtering from the original datatable and now the dataview.
Code:
Public Class Form2
Dim dvFilter As DataView

i've got my basic AutoTyper ready (well and one with autoupdating etc in it) but it's only a singular line.
