I have spent hours trying to fix this problem I have, basically I want to only display column 1 from my text file in my rich text box. Each column is seperated by a space (" ") When I run the following coding it shows all columns.
[code]...
I did this Imports System.Data Imports System.Data.OleDb Public Class Form1 Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
i want to do is run some coding if the value is higher than 0 or if its 0.
Dim i1 As Integer
Integer.TryParse(txttotal.Text, i1)
If i1 > 0 Then
'run code
[code]....
Every single times it keeps running the second part of the coding ie 'run code 2?
I have a complete ms access system build(tables, forms, reports, query). I am in the process of using vb to re-create the system. I managed to show every fields on my vb forms without any coding. However I have some wrong information in my combo boxes. For example I will have repetition(duration, ie 3 months is showing 5 times). Also when I use the arrows only three records are showing. It says 104 records and only shows 1-3. I have also checked all the data in vb that has been transfered from access and it is all similar, ni repetition.

I made a textbox1, button1 and richtextbox1. When I press button1, folder dialog pops up, I choose folder I need and textbox1.text changes to .selectedpath. How to make richtextbox1.text show the folder items I got?
(Example: folder - My Music, items - song1.mp3, song2.mp3, song3.mp3,
so richtextbox looks like
song1.mp3
song2.mp3
song3.mp3)
How I make like this?
There is an option in Visual Studio (since as far back as I can remember) that allows you to see "Whitespace" in your code. This is often seen in file differential viewers as well.
I'm wondering if anyone knows how this can be accomplished in VB.net (or any other way) so that i could use a similar type of display option in my software.
I have not yet tried to do this but my only first thoughts would be to override the "paint" of the textbox to actually add the little tab "arrows" and space "dots" manually via GDI, or create a texbox control from scratch. Seems to me there could be an easier way to do this.
is there any way I can run dxdiag in the background and then show the result in a richtextbox?I know there are tools that can run dxdiag and show you the information.How can I do this so the information appears in a richtextbox?
