I'm writing a windows application that need to access the raw data of the microphone input. Basically there's an electronic circuit connect to the microphone jack, and I need to get that data and process it. All I could find are some examples of using API to save the data to a wav file or something like that. But I need to process the data in real time. Get the exactly value of the input on that time. Is it possible?

View 3 RepliesIt's been a good few years since I dabbled in VB and I'm very very rusty so any help would be great! What I'm looking to do is search an access database with user input and display the relevant record.I have a single table set up in an access database called school_info with the following fields and data:
Tres________DfE________Name_________Type
001________1234________School 1________Primary
002________4321________School 2________Secondary
[code]...
I've linked the database to my new project, connected the database and added the 4 fields to my form. When I run it, the data shows in the boxes fine.The Tres and DfE fields are show in text boxes on the VB form, and the school and Type are show in labels. What I really want to do is be able to manually type in either a Tres or DfE number into the relevant text field and have the other labels auto populate with the relevant data that's stored in the database table.
i have a access database with two tables, one for customer and one for booking.
I then have a form application i made in VS 2008 which lets a user enter details such as their name phone number ect into text boxes.
All of the information the person enters thoughout the program is shown via labels at the end, all on one form.
Would it be possible to then have a button that when clicked saves all of this information into the access tables into the correct columns, im sure it must be possible i just don't really know where to start.
On geting input into DataGridViewTextBoxColumn but the column should not accept input of data that is not integer like; 10003, 2.00, 1500.00

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

View 2 RepliesI've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.
