I have a form which uses a table adapter to read a table:Me.TblOrdersTableAdapter.Fill(Me.WorkDataSet.tblOrders)I want to change it so it only reads 1 specific record (variable at run time). This is for an Access database. To do that I could add a filter to the Fill query or make another query with a filter but I don't know the code to reference a field on a form. Can anyone supply the correct way to reference a field in a table adapter query, if it is possible, or direct me to a better way?
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 using begintransaction to update multi-tables. I need to update one of the table while retrieving some records from that same table before commit. But it seem the table become locked after I inserted a record, and timeout at last.
But that makes the SQL query crash. It doesnt seem as though i am about to put anything related to "count" in my query or it will crash so is there any other way i can see how many records it returns other than that?

To read a record in a binary file in VB^ I would define a type with all the fields specifying strings as STRING * whatever the length of the field was.
For example: Type Record Field1 as string *15 Field2 to as string * 20 Field3 as String * 10 field4 as byte(10) End Type Dim filerecord as record
I would the open my binary fiel and do a Get#1,, filerecord
The record would be read and all the fielsd would be in place.
Now with the new Structure we cant dimension an array in the Structure And wjhen declaring strings we can't specify the length.
I tried to create structire and use a stream binary reader. and just read afixed number of bytes into the type, The program says it canvert bytes to my fiels.
So how do I do this. Or has Microsoft in their infinite wisdom left no way to do this.
I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form.

I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

I don't mind how I do it but I don't want to record all the sound from the whole computer through the sound card I only want the sound from my program. Doing it through a webbrowser control with the swf embedded in a html page is fine or just recording all the sound from my form.
