I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

So what i have is textbox1 textbox2 and richtextbox1 I want to enter information into textbox1 and textbox 2 and then hit submit so it records the data in the richtextbox as if it is a chart.
My current code for this is RichTextBox1.Text = TextBox1.Text & (" | ") + TextBox2.Text & (" | ") + "Pending"
But every time you hit submit it erases the current data and puts the new one. i want it to record it on 1 line, then when u hit submit again it will go to the next line in the richtextbox and record the textbox information on that line and so on.

I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.

im trying to automate entering information onto a printer web interface. I was sucessfully in creating a problem for one particular model printer but not another(differnet manufactor).
HTML button code:
<input type="button" class="w10pt" style="width:136px;display:block;font-weight:700;" value="Login" onclick="location.href='/start/login.htm?arg1=1'">
I tried:
theElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("value").Equals("Login") Then[code].....
it doesnt work .I read this in another post:
"There are several possible approaches; you can try to identify something other than the id, such as the element's name, class, tag name, etc. Another approach is to identify a nearby element, whether it's a sibling, child, parent, etc. that is easily identified (it has an id, or is in some other way unique) and get to the element that you want relative to the element you know you can find. For example, maybe the element is the only child of a </div> tag or a </span> tag that does have an id." So this is the parent to that code:
<div align="center" style="padding:5px;border-style:solid;background:#ccc;border-color: #000;border-width:1px 1px 0px 1px;"><input type="button" class="w10pt" style="width:136px;display:block;font-weight:700;" value="Login" onclick="location.href='/start/login.htm?arg1=1'"></div>[code].....
The site has other buttons that i need to click, so if i can figure this one hopefully i will be able to get the other ones.

I have connection to the Access database in my Visual Studio 2008 solution. Now the problem I am having is when I enter the information on to the form how is it suppose to transmit it to Access? I am sorry to be a pest, but I did not want to take this class eventhough it is required. I only have a few weeks left of class. I have tried looking at a lot of tutorials but it seems to be just repeating the same thing over and over. I wish there was a Visual Basic for dummies that can be accessed on line

After entering data in the first text box I want to make the second text box to get focus when the Enter key is pressed instead of Mouse and Tab control.
Is there any way to do that by making the key values of the Tab key and the Enter key?

I am creating a update member page. I would like the page to auto retrieve the information he or she originally used while registering on my site and display them into the individual textboxes of the update profile page, this is to prevent the hassle to rekey in every individual details and allow the user to edit what he or she wants before it is updated into the database. The problem that I encountered was not able to update the changes in the database. When key in the latest data in address text box and hit submit button, the old data in address text box remains and did not update the database

I am using MS Windows XP, and Visual Basic Express 2008 and I am trying to write a programme that will enter a lot of information into another programme that I have written for testing purposes. The programme that I am writing to has up to 500 line items, by 10 possible suppliers; as you can imagine testing this every time is too labour intensive.[code].....
This code correctly takes me through the various forms until it reaches the Input General Information Form, which opens with the top TextBox in focus. However the entry, "Escravos Gas to Liquids", is placed in the last TextBox.How do I make it enter in the first TextBox, which is in focus? From that point on how do I cycle through the remaining 10 TexBoxes to make each entry?

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

I'm writing software in VB .NET (2005) which uses the Windows user information as login credentials - just the username. I've found Environment.UserName which works for the username (as you would expect).However, I need more information - I need the full name of the user (as shown on the Start Menu). It seems this information is stored... somewhere, as Windows is able to use it for things like permissions on file shares.

I have an app where users form up an e-mail by filling out various fields. They give the form the data, then the e-mail is assembled in the background from all the data they put into the form. Pretty straightforward.
I've added a "Preview" button. When they click, I want a box to pop up and show them what their e-mail will look like when they send it.
I can use MessageBox.Show but these e-mails can get pretty long and as best I understand it, there's no way to control the MessageBox.Show size, word-wrap or add a scroller; so this isn't really appropriate to the overall task.
That said, the information IS all concatenated into a single string with CrLf and such in there for most fields. I just need something that I can send this to and have it create the output window at size X with auto-word-wrap and scroller.
Is there a straightforward way to do this in VB.Net 2010?

I am trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.

How can I access the current user information via LDAP and VB.Net 2.0*? I found a vbscript that works, but I'd rather have it done in .net
Dim objSysInfo = CreateObject("ADSystemInfo")
Dim strUser = objSysInfo.UserName 'returns current user account
Dim objUser = GetObject("LDAP://" & strUser) 'queries active directory for user account
I'm using the framework 2.0 because it is for more likely in my XP/Vista/7 World to have 2.0 installed than 3.5 or 4.0
