I want a box(listbox or textbox) in VB.Net form. then when I running the program, user can type a value in the box. can I ask user to type and read the value user typed into a variable. Example: User type 4.137, the program will read 4.137 and assign it to a variable A. I try to find the syntax to do this on VB.net but I have no luck finding the right syntax to read the value. I using VS 2005.

In both C# and VB, type parameter modifiers are used to express the variance of type parameters. For example, the C# version looks like:
[Code]....
Since variance specifications basically restrict where and how a type parameter can be used, I tend to think of them as additional constraints on type parameters. I'm just curious as to why they aren't represented so. I mean, why are they represented in both languages as additional modifiers on type parameters, instead of being added to the type constraint list? If they were type constraints, the C# version would've looked like:

Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.
There was a syntax error while converting from one data type to another. [ Expression = -1 ].
This part of the code where the issue starts is here: Do While JVReader.Read()
Here is the
CODE:
Public Pixels(0 To 95, 0 To 127) As Variant Red = Pixels(X, Y) And &HFF i get this code from VB6, and when i transfer to VB05 i got problem said " Operator 'And' is not defined for type 'Color' and type 'Integer'. " i sent to VS2005
Public Pixels(0 To 95, 0 To 127) As Object
Dim red As Object

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.

View 10 RepliesI am using vb.net 2008 and sql 2005. I am writing a program to translate data from one database to another. Basically I have two dataGridViews, the original data is automatically populated to the first and on clicking the "Translate" button the second dataGridView is filled with the translated information. I am having trouble with the syntax of passing a value from the original dataGridView to SQL and returning the 'id' of the translated data table. For instance, the original has colors stored as "Blue" "Green" etc The new tables now have unique ID's with the color name as attributes. I need to basically be able to pass dgvOriginal.rows(i).cells("color").value to a stored procedure and get the "id" field of that color. Here is what I have so far.

I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values.

I need a 2-listbox mover/selection type control such as the example here: [URL] For over a week now I've searched countless forums and done myriads of googles. All I've been able to find is C++ or ASP based stuff. I really would like this to be VB.net, but at this point, I'd even settle for C#.
I've taken a shot at developing it myself, but am too new to the .Net world to really get anywhere with it other than being completely overwhelmed and frustrated. I've even looked at some 3rd party custom control webistes, and am even willing to spend a few bucks for this thing, if I could find one that suits my needs.

I am trying to write a class to implement search as you type. e.g. a form has a textbox and a listbox. Each time the textbox text changes, the list is the list box is filtered accordingly. E.g entering "ha" in the textbox would cause the filtered listbox to display 'I plan on implemtneting a sayt class.(see example below)
The thing I am having problems is working out how the two controls will 'talk 'to each other.
e..g when the textchanged event fires for the textbox, how does a sayt object 'know' that it needs to refilter the listbox?
