VS 2010 Textbox With Index?
Jun 20, 2012
In VB6 you could use textboxes with an index so textbox(1), textbox(2) and such. Now I need something like this in VB2010 and it seems that VB2010 doesn't work with those indexes. Now I need to following:
I need 3 textboxes and 3 button, (where button 1 belongs to textbox1 etc.)for a path on the hardrive(s). 1 will be source, 2 will be copy path and 3 will be compare path. Those 3 I want to set with only 1 drive/folder sub.
In VB6 I used 1 sub for the buttons and use something like textbo(index).text = strDriveFolder. Where the index is the index from the buttons, because those are the same.How can I do something like this in VB2010 when it is not working with those indexes?

I want some syntax when I tell to get me the index 1's value, it gives me "h", for index 5 = "o"... etc
So, anyone knows what's the right syntax,

I added a textbox and a button to my form. In the textbox I've wrote "Hello my name is eddy and I'm 17" so when I click the button , I got the textbox length .
My code button on click is :
textbox1.text = "hello my name is eddy and I'm 17"
msgbox(textbox1.length) ----> the length is 32
Now my question is how to get the index of the word "eddy" in the textbox and as you see all the text written in the textbox has the length of 32 and the number 7 which is the last letter in the textbox has the index of 32. So how do I get the index of the word "eddy" in the textbox.

Create an application for maintaining payroll for a business. When your program begins, read in an input file containing delimited employee records (a sample is provided in the assignment); each record contains the employee name, the current salary and the number of years employed. Display only the names of the employees in sorted order, and when the user selects a particular employee, display the salary and number of years employed for that employee, allowing the user to edit the record. Provide methods of adding and removing employee records as well, and update the input file with all changes before the program close
I want to put the salary and years into separate text boxes. Heres my code so far, I realize its certainly not the most efficient way, but its functional.

how to validate and save the results of a textbox when I change to another tab on a tabcontrol?I have found the SelectedIndexChanged and LostFocus but they do not tell what was the tab that has been previously selected, so I then can do that validation and save. is there an event that triggers before the SelectedIndexChanged?

I'm trying to create an ASP.NET web application to enter the winners of a science fair. I have a gridview that contains bound fields for the students' IDs and names and template fields with comboboxes from which the user can select the award, place, and prize amount. I want the user to be able to change the values in the template fields, then hit the Submit button and update all of the records in the database (SQL Server 2005). The code below seems to be on the verge of doing what I want, but I'm getting the error "Index was outside the bounds of the array" on the line in red:

I have a class that inherits List<T> [this is a C# project, but it can relate to VB.net] but I want to know if there's a way to force the index to return something else....let me give an example:
In the original List<T> implementation, whenever you call for an item on the list, like so:this[0];You get whatever T is. What I want to do is override that, and grab whatever T is, then return a certain value of T.

I am trying to test is the innertext of a <td> tag corresponds with an <input> tag before clicking it. To be more clear I have a list of the MAC Addresses in my program and I want to delete a selected MAC Address from the website that matches the selected one.
I tried this
WebBrowser1. _
Document. _
GetElementsByTagName("table").Item("listTab").GetElementsByTagName("input").Item(selected item index).InvokeMember("click")
But not knowing the right index of the MAC Address that matches it just deletes the wrong MAC Address.
