Read MP3 - Write Wav?

Jun 13, 2009

Is there anybody out here in the VB, C# 2008 world that can direct me in the right direction? I do not want anything that has todo with c/C++or Direct Draw. When converting, there is no equal for SizeOf, and a few other things. I am using Lame 3.98.2.exe in my app along with LameShell that works fine for resampling, but , not for decoding an mp3 to wav or encoding a wav to mp3. You can find the LameShell project at [URL] .

VS 02/03 Xml Read & Write?

Dec 21, 2010

I am trying to extend an application to to write the details from textboxes on a invoice form to an xml file.I have created 3 methods for my invoice class which will open the invoice xml document, write to it, and close it.The open Invoice method creates and invoice.xml file and writes a start tag named invoices.

The WriteInvoice method writes an invoice element for the invoice with attribute named customerName and three child elements named ordertotal, discounTotal and Invoice total. These values are taken from the textboxes form the form.

The CloseInvoice writes the end tag for the root element(invoices) and closes the file.

I have wriiten code for these methods but can only get the open invoice method to work.

My code for the 3 methods is shown below:

Public Sub OpenInvoices()
Dim sInvPath As String = "C:MurachBeginning VB.NETExercise startsVB.NETChapter 14InvoiceInvoices.xml"
Dim InvoiceWriter As New XmlTextWriter(sInvPath, Nothing)
InvoiceWriter.Formatting = Formatting.Indented 'Set formatting of XML file

Read And Write Files?

Jan 27, 2010

reading and writing files. Let's say I have a text file with multiple lines that I want to be read into my visual basic program. The first line is displayed in textboxA while the rest of the lines are displayed in textboxB. How do I accomplish this? Am I able to use the peek method for textboxB but somehow tell it to skip the first line? Now textboxB is obviously a multiline textbox and I want the user to be able to type something into another textbox (textboxC), press a button, and it will be displayed in textboxA. How do I make the text in textboxC get displayed on the first line of textboxA and move all the other lines down the list?

Read/write Some Data ?

Feb 13, 2012

My first question has to do with the opening lines needed in a VB program in order to connect to Excel 2007 and read/write some data from/to it. I know the process only slightly and reading and writing to the cells is not my real concern for the moment. What I need to become familliar with are the lines like this:

CODE:

This is just one of the examples I have read through and to be honest I only follow this slightly. The trouble was that with each new article I read, people did this differently, not the variables on the left mind you, just that some left out lines, which I can see could be done based on circumstances. Still others said the Imports line was not needed....etc...and other loaded up at least 3 or four more Imports lines insisting all were needed.

I'm looking for some straight-forward advice on what is the minimum needed to access an existing Excel spreadhseet and to just read some of it's cells to variables in the code and then writed some data back to certain cells within the spreadsheet and then save and close it.

Also, please note that I am using VB 2010 Express. Why, because I'm a broke developer who spent most of last year out of work. I have a new contract assignment which is so far going well but will go even better if I can master this technique with VB.NET, not VBA. And all the docs I've read said that even though VB 2010 Express is a watered down version of VS, I should be able to do medium level tasks such as this with it.

Read/Write To Other Applications Using WPF-VB

Dec 9, 2009

Trying to emulate a typing application that when typing data in a WPF form, the info gets transferred to another application, such as notepad, word, etc. My first attempt involved using the .Sendkeys method but it doesn't seem to be repeatable 100% of the time. I initially had a button that when pressed would transfer data from a WPF app field to an open notepad app. Again, if I pressed it several times in a row, it would be hit or miss. It's like it hangs up and then after enough time, I try again and it works. I really need it to be 100%. Is there a fix for this method or should I take on a different approach? It would be ideal if I could go from notepad, word, etc. back to the WPF form as well, but I thought I would get one way working first.

SyncLock On Write - Read - Or Both?

Jan 7, 2011

Suppose I have a byte array, Private Data as Byte(). This array is private within a class. The class provides public functions for reading and writing to Data. This class can be accessed by multiple threads, so I want to avoid a situation where reading from it and writing from it don't happen at the same time.

For now, I am using SyncLock to avoid issues. Can I put SyncLock Data in just the write functions, or does it need to be in the read functions? Or, both? I don't have a specific code example in mind. I am just curious if there is any benefit to locking for both read and write functions if the writing functions' SyncLock will make writing have exclusive access to it in the first place.

my question is, is that code used properly for writing/reading those 2 files?

.net - Isolating Read And Write In Multithreaded

Mar 8, 2010

In a multithreaded application. I have a bunch of function that loop through a collection to read the information. I also have a bunch of function that modifies that same collection.

I'm looking for a way to isolate all the read and the write together. I don't want a write to be done while a read is in progress. I was thinking of using SyncLock on the collection object but this will block multiple read trying to work in parallel.

.net - Read This DataTable So Can Write It To A CSV File?

Jan 3, 2012

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)

Feb 25, 2009

for starters not sure if this is the right place for the post considering that it includes MySQL and VB, its here.I'm trying to load data from one table into a combo box as the data you can select, this i have been able to do "tbl_Wind" using "WindDirID" and "WindDir"

also, I am trying to select (if it exists) a value from "tbl_date" "WindDirID" to select a value from the existing data in the combo box loaded from "tbl_wind"and finally, I want to be able to change the value in the "tbl_Date" depending on if a value is selected in the combo box.when a new record is created in tbl_date it uses default values, so there is always something in the field.below is about how far i got, and its the only part that works (extracted and edited of course to exclude the other queries)
