I am trying to open an audio device using the waveOutOpen function in winmm.dll and receiving a WAVERR_BADFORMAT error. It was working fine when I was just using the WAVEFORMATEX structure alone but unfortunately this has the limitation of only handling 16bit audio and I would like to handle higher resolutions.

I am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.
I have all of that working.
When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...
My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?
I'm looking at an old web app I wrote and it is taking about an hour to read 4500 records from a DataTable so it can write them to a CSV file.
The DataTable contains... 376 columns
At least, I think that's what Excel's NL column converts to. I just looked up the column count now and had no idea there were so many. Our software vendor hasn't realized the value of dynamic sql statements for this process, so every software "upgrade" just keeps adding more columns rather than only selecting the ones needed. I cannot alter the SQL statement that generates the data
Depending on the data type, the data needs to be formatted in a specific format Data does contains special characters, such as commas The slow part is reading the data. Getting the data from the SQL server and writing it to a CSV is fast.
Here's the code. Forgive the mess, I wrote it back when I didn't know what I was doing and when I still was working in VB
Function ReadDataTableForCSV(dt as DataTable)
Dim sb = New StringBuilder()
Dim dataTypes As New Dictionary(Of String, Integer)

I was unable to find anything in my searches for XML or INI on the forum so i apologize now if this has already been asked and answered before.
I have been searching Google for days now, trying to find information on Reading and Writing XML files. I wish to use them to replace INI files in my programs.
I have been using VB6 for years now, but was able to get a copy of VB.NET 2003 really cheap and so i am trying to learn how to do the things i did in VB6 in VB.NET 2003.
I was able to find code to write to an INI file, but was not able to successfully read from an INI file with any of the code i found.
I have been able to find code to write an XML file, but when i try to update it, it replaces the old file with a new one, and the old settings are missing, instead of the new settings added to it.
i can at least start migrating to VB.NET 2003, or if you read XML and update XML data, i can switch now. Here is the code i have for writing XML.[code...]
I have search on google but i have just find this function SteamWriter. This fonction for writing work, but the script create always a new file... I want write under the last line.And with your fonction, how i can read it line by line for use in select menu.

I have a text file which look like this:

After two days of looking I give up. The basic problem is that at the end of my program I need to be able to write out a text file and then read that same text file back in when the program restarts or reopens. The best and easiest way I have found to read in the file is to place the text file with in the Resources and use this code.
Dim ReadingIN As String = My.Resources.Mytext
So then I want to be able to change that string and then write it back out. Part of the problem is I want to be able to use this from a flash drive or a changing directory.
I have tried but it doesn't work
Dim WritingOut As String = ReadingIN + "Edited text"
Dim DirString As String = My.Resources.Mytext
