View 4 Repliesi am wondering if it is possible to make a program with visual basic that records from the microphone, then converts it into a midi file.
View 2 RepliesI am looking into recording sound from a microphone using vb.net into a wav or mp3 file. I've Googled loads but only found 3rd party controls and C# code, which looks too sticky to convert..[url]...
I found this article on the code project which uses WaveIn and WaveOut but this looks unconvertible.... and I would like to avoid using DirectX SDK because the installation files are large and I wouldn't like users to have to do that.
I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
How can I make a program to record sound from the microphone? I've tried lots of thing but they don't work. Can someone show me how to do ths using winmm.dll or DIrectx?

View 15 RepliesI am currently working on a flatfile based database, meaning: all database records are saved in single files in a data folder of my main application. So far everything works fine except for one thing:
Each record gets currently saved as file under its item name. This sometimes causes problems because some item names contain special characters which can't be used as a file name. What I would like is the following: Whenever I 'add a record' to my database it should be saved in a file with a 4 to 6 digit number as file name - to keep things simple I just ignore the file extension for now.
For example, I add a new record with the ITEM NAME Flower "Blue River" #1 - I won't be able to create the file because of the special characters in there! I would like that the program creates automatically a file in a 4 or 6 digit format (I haven't decided yet how many digits because I am not sure how many data records I will need one day, so, 4 digits will be enougth for now!), starting at 1000, so, the file I am creating is called 1000 + whatever extension I will give it later.
In addition, I would like that it checks for missing numbers in between when creating a 'new database record', meaning: I have already the folloing file names: 1000, 1001, 1002 and one day I delete the second record, so, 1001 would be available for the next new file / data record which I add to my database.
So far I've experimented with the GUID but the filenames I get out of it are just not in an 'eye pleasing' format. Would there be a way to give this GUID a special format or is there any other good way to accomplish that?
Basically, I am making a booking system. On one of the forms, you can: Add, Edit and Delete a record by using the selected index. I can do the Add and Edit part fine but some problems are occuring when I try to delete it. What I'm trying to do when deleting is, copy all the records except the selected one and then copy it back into the original file again.

I've reduced my massive test code to the above for this post.
In the above iFormat is the BMP image format.
The picture box displays the correct image but the saved image shows in Windows Explorer and Paint as all black.

View 2 RepliesI am developing an application in VB.net 2005 and using Access Database. I have the database and the application working very well. what i want to do is to convert the a tabel in the database into a text fileI wrote this code into a button which i should click and pass a database tabel name as a parameter and a textfile name as an output.I can write into a textfile so far and this is the code i am using .
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code].....
So i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database
Option Explicit
Function GetFilenameFromPath(ByVal strPath As String) As String

i have this program i need to make, where it runs a bat file. i got that far, so when i click the button it opens the bat. but 3 problems i encountered i have been trying to resolve for a few days now, the problem is that i need to get the output of the .bat and display it in a textbox, i got that, but it only displays the first and least line... then i need to run the .bat in the background. so you don't see the window.then i also need to be able to hit a second button to close it. the bat is a constant update, lets just say it reads a number then 5 seconds later adds 1 to that number and displays it again. and does this over and over till you close it. that would be a simple description of this
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "C:\Users/jwoow/Desktop/Server/run.bat";
p.Start();

I'm having trouble dragging a record from a linked file. The structures for the three files

Recently I experiment with the binary file type. I have this structure[code]...
It works. And now, in the load event of the form I want to know, how many records (structures) are stored in the file.
Another question: how can I search and seek in the file (structure to structure, not byte to byte)?
Let us suppose a 256 colors picture (bmp or jpeg) with a size of 500 x 500 pixels.I would like to allocate a code (1 to 256 max) to each different color identified and put that code in a 500 x 500 table of a .xls sheet, all positionned at the right place.Additionnally, I would like also to place a chart illustrating the different colors and their respective code at the bottom of the sheet.
View 24 RepliesTo 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.
