Save Field Without Displaying It On The VB Form?
Nov 23, 2009
I have a VB 2008 windows application that I'm working on; the data are stored in SQL. I have a lot of fields that user will need to fill out. Some fields that not displayed on the form are actual combination of few filled out fields. For example - user types in first name, middle name and last name in 3 separate boxes on the form and I'd like to combine those and assign it to the "FullName" field. I know it's duplicating the data but this FullName field would need to be merged into report as is in a different program.
Another example - user will pick a data in combo box that is binded to a different table, but I need it to auto-populate 3 fields in the main form (those fields are not displayed). I know that I can actually add all those hidden fields on the form and assign calculated values based on user input and then everything is saved with built-in "Update" command. I was wondering if there is a way to specify those few calculated values as parameters and still use "Update" command without actually typing long Update command. I have over 400 fields - very lengthy command.

I have a table and I want to select a field in it and then display it in a text box
something like:
SELECT userName
FROM userTable
WHERE (userLogged = 'ON')
how can I display the selected username in a textbox?
BTW the userLogged indicates wether the user is logged in or not
if the user is logged in then the userLogged will be changed to "ON"
if the user is not logged in it will be "OFF"
I know it's not that practical but I'm still practicing.
I'm using Visual Web Developer 2008 Express I use table adapter procedures for querying

If I have a store procedure that call the 'field_name' and 'field_id', but I want to enter the 'field_name' into a form where I need to select information that will be used in a Crystal report. When I enter the 'field_name' it needs to use the 'field_id' as a parameter for the selection of the data on the report. How would I do that?

I have a "For
Each
Row As
System.Data.DataRow
In
DataTable.Rows" type loop. I want to save the contents of a field to use in subsequent processing.
It looks to me like the proper way would be to use something like the following:
Dim saveCatalogWorkID As VariantType
For Each clsWTRow As System.Data.DataRow In clsWTDataTable.Rows
saveCatalogWorkID = clsWTRow.Field("CatalogWorkID")
Next clsWTRow

I need to save the form settings, like a save state of the form. Because the program allows the user to add controls. I would like to be able to save them and load them. BTW: The controls are Panels and Labels. BUT! The Panels are a modified version of the control, known as NewComp. This simply allows the user to drag the panel around the form.

I've created the beginnings of my new web application, but I am often coming up against the issue that ASP.NET renames elements IDs or in the case of form fields, their names.I have a form which is basically a sales system. It is essentially made up of two User Controls, one is a form for Customer Details (name, address etc) and the second is a form for the customer's purchases, it consists of a number lines dynamically created by Javascript created as you list the items the customer is purchasing. Both these sections are User Controls because they are to be used for other areas of the system where this data will need to be recalled/re-entered.When the USer Control is loaded, the field which contains the Customers' Name is renamed "m$mainContent$customerForm$name" I understand where this comes from, "m" is the ID of my Master Page, "mainContent" is the main Content Placeholder and "customerForm" is the name of the User Control.
In fact, in my case, this will always remain the same on all forms, so it is relative easy to overcome... but... suppose it wasn'tI can see there are ways I could deal with this with Javascript, but the form doesn't need an AJAX submit, a normal Post will do fine for this, so when I open up the recieving page I want to call Request.Form("name")% to save the customer's name into the database, but of course I really need Request.Form("m$mainContent$customerForm $name")%How would I dynamically extract those prefixes from the posting form to ensure that if I rename anything or use it in a different scenario, the problem will not break it?I am using .NET 2.0, so can't use Static Client.

Whenever I modify a file in the IDE in Visual Basic Express 2008, and then press the "Save" or "Save All" button, the "Save As" dialog opens, then says that a file of that name already exists and requests confirmation of the save. This didn't happen in Express 2005 as far as I remember.

I've been working on a project now for some time and as a result, when I have something new to try out, I do a little "proof of concept" project and then port it over to my real project (mainly to make it easier to follow when trying to work out new issues).Up to now, I've been relatively successful at it.But here's what I'm running into with this particular project.First, a little background.When the operator enters data into certain input fields (textboxes), either a listview or a datagridview appears displaying multiple columns of information.Once the line is selected with the proper info (equip. id or type of job or whatever), that info gets displayed in the textbox.The problem occurs when display is clipped by the window size.Let's assume for simplicity sake that I can't enlarge the display window.
So I rethought that and decided to create another form that has no borders and the only item displayed is a bound dgv.So I created a proof of concept project that consisted of two forms: form 1 that contains a text box and form 2 that contains a dgv control.when run, form 1 is displayed.When I type a character in the textbox, it calls form 2 and searches the dgv for the first char I entered.Since form 2 is the current form, as I enter additional chars, I build the string, search and if the chars are valid input chars, echo them to the textbox.Once the data line on the gridview is found, the tab key is used to do the select, close form2 (the dgv) and populate the textbox of form 1.This all worked.That is until I tried to port it over into my real project.This is where I'm obviously missing some key aspect of VB.Net and how all the forms and threads and handles work.To get right to the issue and skip alot of what happens in my real project, I was able to duplicate the problem by just creating one more form in my proof of concept project that just has a button on it.That button when pressed, brings up form 1.When I start to type in the textbox, after I enter the first character, form 2 displays, which is as expected. But when I enter the second search character, a second instance of form 2 opens and it searchs for the second character I typed.If I enter another character, it gets added to the second char and located in the dgv of the second instance of form2.When I press the tab key, textbox of form 1 does not get updated but the second form2 does close.The first form2 remains.

I seem to be having a problem with displaying data in a second form. I've created a linear search algorithm which works just fine - it locates the records from the database. I now want to be able to display the record in another form, I've attempted this using the code below but it doesn't seem to work:
Public Class formSearch
Dim searchItem As String
Dim currentRecord As Integer
Dim Provider As String
Dim Source As String
[Code] .....
The commented out lines are the ones that don't seem to work. The "txtfirstname" and "txtlastname" fields are located in the coding of another form, called "formcustomers".
