Wow - are you even remotely a programmer, or is this an error from software you use and you're asking about it in a programming forum ?

Hi all...

I am creating a program in which is used to play two songs at the same time.
I have imported Interop.WmpLib.dll file and created two objects to play two songs simultaneously.
I want to mix and record these two songs so that when I will play recorded file, it will play songs of both files as played in DJs.
Suggest me,how can I mix and record these two mp3 files in one mp3 file.

Thanks.

Your going to need an audio processing library to do this. Try Googling for "mp3 processing library .net".

For editing MP3 files you will need a DLL, LAME32.DLL is a good place to start, the open source Audio editor called Audacity also uses this DLL.

Issue with : Setting system time

Hello every one

I am working on a application in which I have to change the system time. After googleing for some time I found some help and did the code as written billow.

It is just a test code in which I am adding 2 hours in the current time. The code is working but it dose not just add 2 hours but some thing around 5 hours.

I tried debugging it but was not able to know what is wrong. I even tried without adding 2 hours strill the time changes by around 5 hours

Any idea what wrong I am doing?

<dllimport("kernel32.dll",> Public Shared Function SetSystemTime(ByRef theDateTime As SYSTEMTIME) As Boolean
    End Function

    Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click

        Dim st As SYSTEMTIME
        'Dim st As SYSTEMTIME
        st.wYear = Now.Year
        st.wMonth = Now.Month
        st.wDayOfWeek = Now.DayOfWeek
        st.wDay = Now.Day
        st.wHour = Now.Hour +2
        st.wMinute = Now.Minute
        st.wSecond = Now.Second
        st.wMilliseconds = Now.Millisecond

        'newDateTime = st

        If SetSystemTime(st) Then
            'cool, we set it successfully
        End If

    End Sub

Regards

How about getting the system time first, then adding 2 to the value that's there, instead of populating the entire structure.

But, the major problem is that you're Trying to assign a Singed 32 bit Integer to an Unsigned 16 bit wide field. The value overflows and you get weird results like this. Try something like:

st.wHour = Convert.ToUInt16(Now.Hour + 2)

It's not supported by the standard control. You'd have to use either a third party control or write your own version, supplying all the appropriate painting code to do so.

Look at any number of the recent tutorials/guides on code project which show you how to do this. There was one posted just today or yesterday.

hi dear,
i've some frames created in Adobe Illustrator and i want to implement them into different pictures using VB.NET... plz help me how to apply these frames in VB.NET...?

many thanks,

It's very unlikely you're going to get an answer to this question considering, in 6 years, your the first person to ever ask a question about Illustrator around here. I haven't touched Illustrator in over 10 years.

AFAIK, the only way you can use those frames is if you export them as bitmap images. The .NET Framework has absolutely no support for Illustrator's file format biult in.

I suggest Googling for "VB.NET Illustrator" to start.

Google for "System.Io.Ports.SerialPort" and you'll come up with dozens of examples and documentation.

Talking to an external piece of hardware on a serial port is no different than talking to a PC.

Ok, sorry for asking stupid question. But i am quite new to serial communication. Another question i have is why when i
Dim Withevents Port as serialPort = New Serialport, is labeled as error as undefined. But i have already imported the library.

Did you put this at the top of your code??

Imports System.Io.Ports

And are you using .NET 2.0 (Visual Studio 2005) or greater?
