I'm wondering if anyone else has encountered this in visual studio 2008. I'm writing an asp.net app and when I run through debug it's jumping all over the place. It skips certain lines, at least it appears to, then it jumps to the bottom of the page and repeats the same line a few times then jumps to a separate sub I have in there. The weird thing, besides its behavior, is that it's not grabbing a piece of information that exists in one column but is grabbing another one. So anyone else encountered this? What's the fix.
To give a more detailed example it did this on the last debug. I started the breakpoint at line 40. It went to 43 with no problem then jumps to line 66, an end sub line, it then proceeds to go on to the private sub directly below it. That includes it going over the blank lines that would normally be skipped. It goes through the entire private sub line by line including a catch ex line but it displays no error. After hitting that line it immediately returns to line 46 of the sub that it already passed by the end sub line. It then goes down 2 more lines jumps back to the private sub it just left and repeats the end sub line 3 times, only the b at the end is highlighted when doing this not the whole line.
I have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"
Here's my code on add, update and delete
Public Sub SaveRecord()
Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....
Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"

Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.

I'd like to build a class where I always have a button at the bottom of a form.Then when I drag and drop the button, It has to make a copy of that button called "button1", if I drag and drop the button again I'll have another button called "button2" and so on.But If I drag and drop the "button1" or "button2" they shouldn't duplicate as the original. And this is the problem I can't sort out.
This is my class:
Imports System.Windows.Forms
Imports System.Drawing
Public Class frmTablesEditor
Inherits Form

I have a form where I want buttons at the very bottom edge of the form, with no gap to the border. These buttons shall be "auto-hide", so they only show when the mouse is in for example the lower 20 pixels of the form. So I use the MouseMove event to trigger this, like code below. However, if mouse leaves the form across the bottom edge, where the buttons are, then the buttons will obviously remain. But I want them to hide. So I need for this purpose to hide the buttons by some other event. Hence I try to hide them in the form's MouseLeave event. But this makes the buttons unclickable and in an erratic state, flashing on and off when the mouse goes over the button..
Private Sub ZgScale_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase. MouseMove
If e.Y > Me.ClientSize.Height - 30 Then
Button1.Visible = True
Else[code].......

View 1 RepliesI've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

I am creating a notes software. This is just a simple application that will show the data from the database which are Notes_Title, Due_Date, Priority. I display the data with datagridview. I also added a checkbox for each row to the datagridview to mark as check if the Notes_title is already done. In displaying the data, I need to display only a 5 data in a row.So, I create a another CLASS that will only show 5 rows per page. But the PROBLEM is, if I mark the checkbox as check in the first page then if I turn it to the next page the checkbox in the first page that mark as check will be uncheck if I turn it back to the first page. The mark check in the checkbox will mark as uncheck if I turn the page. How can I make it mark as check even if I turn the pages? And How can I save the data row as done if I check

I've set up a basic loop to delete all the files in a particular folder. I've set the loop in a Try block so it doesn't crash the application when it gets to a file it can't delete. I'd like for the app to just pass over these type of files. At the moment, my loop stops completely when it gets to that exception.
