I build an application that has two forms; one gets an employee info and stores in on a txt file (I accomplished that) and the other for viewing the records and searching for a record. I'm having troubles with viewing the records one by one when I click on the "Next Record" button.
The code below is only for view form
vb.net
Imports System.IO
Public Class frmView

I have a system which needs to be secure which streams relatively large documents from a webservice to a proxy (Web site) whch then grabs the stream and pushes this to the client. This works but there are some issues where it seems the response is not being pushed until the entire stream is complete? whether this is the case Im not sure have run charles and until it completes it is "Waiting for response".
The documents are currently PDF but it needs to handle many other types for the future. The octet stream etc is mostly testing related, how to get the Dialog to show - saying save as? for the large files the little ones don't matter to much but the big ones leave a big waiting period with no response.

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 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.
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.
