I want to use FindBy method to return record in a datatable and show the fields in the corresponding textboxes and other controls. The DataTable in which i am looking is already bound to these controls, maybe when I use the following code (which is not working correctly, hence this thread) the fields will show up rightaway?
{
Dim MoviesRow As New_Movie_DatabaseDataSet.My_Movies_TableRow
MoviesRow = New_Movie_DatabaseDataSet.My_Movies_TableDataTable.FindByID(ComboBox1.Text)
}
This is the error:
reference to a non-shared member requires an object reference.
I wanted to import Microsoft.Practices.ObjectBuilder2 but that does not work either.
The form it is on is frmMidwest.vb, the database is MarchMadnessDB, with the table being tblMidwest and the column being Username. I am trying to get it so when the user loads frmMidwest.vb it will then check the database to see if the user has entered their picks and if they have it will load their picks back into frmMidwest.vb if the database cannot find their user then it needs to add a record to the database and allow the user to enter their picks. I have already established this with
TblMidwestBindingSource.AddNew()
But if the user exists I do not want them to be able to enter another record. The primary key in the database is the username.
I have a Datagrid contain IdNo, EmpName, Address, PassportNo, WorkingAreaCode on my Windows Form (VS2010) with a Textbox to search records. my requirement is if I enter any required details in the search Textbox that should search all the columns and filter records.

Another user came up with the following code. However I was hoping to find something that is more directly supplied by the system, rather than a "roll your own" solution such as this one. Also, the solution below could run into problems, however unlikely, because it is possible for Windows file and folder names to contain semicolons. The split function doesn't pay any attention to quotes, and could therefore improperly split a path that includes a folder name with an embedded semicolon.
Private paths() As String = Split(Environment.GetEnvironmentVariable("PATH"), ";")

My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).
If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...

I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

I'm calling a 3rd part app which 'sometimes' works in VB.NET (it's a self-hosted WCF). But sometimes the 3rd party app will hang forever, so I've added a 90-second timer to it. Problem is, how do I know if the thing timed out?
Code looks like this:
Dim MyProcess as System.Diagnostics.Process = System.Diagnostics.Process.Start(MyInfo)
MyProcess.WaitForExit(90000)
What I'd like to do is something like this
If MyProcess.ExceededTimeout Then
MyFunction = False
Else
MyFunction = True
End If
Before I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before.Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on.So in this text file, there is a bunch of info, but I am only needing a certain part.Here is an example of a text file (actually a .dat file, but is easily read):
s t y l e T h e m e d s h y - A l p i n e V i l l a g e S e t S t y l e & h y - a v p o s t 1 H a n g 3 , V ¯s t y l e T h e m e d s h y - A l p i n e V i l l a g e S e t S t y l e , y - a v p o s t 1 H

I have a textbox for searching a database. When the text changes it runs a functioncFilter() and loads the records. It is set up to search different columns of a database, and it unfortunately only the first record matching is pulled from the database. Example: when the database contains two people (Bob Smith & Bob Smitt) the user can type the name in the search field. However When the user types Bob Smit it only returns Bob Smith and not both names in the database. I want this to act as a filter, dynamically changing the last with each additional letter typed in the search box. Below is my source code,
Public Sub cFilter()
Dim myConnectionstring As String = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & My.Settings.dbLocation & ";Persist Security Info=True;Jet OLEDB:Database Password=BCFAdmin")

View 2 RepliesI am trying to do a SQL query to see if an Address already exists in my database. My addresses are structure like this:
line1
line2
line3
city
state
zipcode
country
Sometimes line2 and line3 are NULL values in my database.I am using .NET TableAdapter and DataTable to make my query. When I try to pass in my line2 parameter (@line2) it is equal to a string with value = nothing. My database does not interpret this as NULL and says the records don't match, but I know they do? How do I pass in a string = nothing and have it compare to a NULL value in the database as being equal? I have tried string = DBNULL.value but won't compile.I have done similar comparisons with integers etc. using integer = Nullable (of integer) but this does not exist for strings.
I have written a code which adds some information to a database. No problem with that since the records get inside the database. My problem is that the record I added always shows up on my Search. I tried changing the variables so that none will have the same names between the two forms but it still shows.Example:
1. I added a record of a book which has an id of 1, name of Cisco, and total of 50. I added it thru the debug function.
2. I added a record of a book which has an id of 2, name of Link, and total of 30. This time, I added it directly on the database file itself.
2. I created a search button which will show records depending on the input of the user.If I type "1" for the ID, the first record will appear on the datagrid. If I type "2" for the ID, both records will appear. If I type "3" which I doesn't have any record with, the FIRST record will still appear. To summarize it, the record that I added through the program itself will always show up on the query results, no matter what I type into.
