I know how to search for one specific number from a single line in an access database using a query, but now I have to search through a whole database and display each instance. Ex) I search the number "1" in column "1" of the database and it has "2" instances. So now I have to take the corresponding data in the rows next to it in order to display them in the label.
search: "1", both results are ID = "1"
results:
dates amount
10/13/2009 $43.00
12/25/2009 $86.00
I know how to put the results for "1" line of a database into the .item field, but im confused on how to search multiple lines of a database and store multiple items. Heres what I have so far...

Searching for data in Access then showing output with VB 2008
View 6 RepliesI am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)
Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

I am having a problem. The IO.Directory.GetFiles code is resulting in error do to the fact that it is trying to access the Temp folder in the Windows folder on drive C:. Apparently that folder is restricted... When the code encounters that folder the code stops retrieving files. Is there a way around this? Is there somewhere i can give my program administrator access? If not then am i able to skip the files in that location?
If any directory within a set being searched by the [URL] or [URL] methods contains a junction point, the entire method fails and returns zero results on my tests under VB 2008. I would like to make the call more robust: to return the folders or files not blocked by access restrictions and to note the folders which were blocked. Do those methods offer a means to do this, or is a recursive folder-by-folder call necessary?

how I can search through this data table. For instance, I want to see only rows that are in this data table that have "Replace" somewhere in the "Description" field, which is the field I added from my second data source. How do I do this? Is there an easier way to do all this instead of filling my dataset from the first source and then adding columns from the second source by looping?
I'm in the process of moving from ADO.NET to Linq. The application is a directory search program to look people up. The users are allowed to type the search criteria into a single textbox. They can separate each term with a space, or wrap a phrase in quotes such as "park place" to indicate that it is one term.
Behind the scenes the data comes from a XML file that has about 90,000 records in it and is about 65 megs. I load the data into a DataTable and then use the .Select method with a SQL query to perform the searches. The query I pass is built from the search terms the user passed. I split the string from the textbox into an array using a regular expression that will split everything into a separate element that has a space in it. However if there are quotes around a phrase, that becomes it's own element in the array. I then end up with a single dimension array with x number of elements, which I iterate over to build a long query.
I then build the search expression below:
query = query & _
"((userid LIKE '" & tempstr & "%') OR " & _
"(nickname LIKE '" & tempstr & "%') OR " & _

I will include a link to a copy of my source Code. The Problem is that I have to create a user management system. I have almost all my features working but there are one or two I can't get working. When the program loads a text file is read and the program lists the first name of everyone in the text file into a list box. I want to be able to get so that when you click a name in the list box, the persons information will be displayed in the text boxes to the left. And also when you edit those text boxes you can click the button for modify current and it will modify that persons data. The other problem I'm having is being able to search that text file for the users e-mail and return the first names of people who have that e-mail into the listbox.
