How can I merge two or more MP3 files in VB .Net application. I have to first read the file and then merge them and write the merged entity to new file
|
|

What do you mean by merge? So that you can hear both files at the same time or are you adding one file to the end of another?
In either case, you'll need an in-depth knowledge of how MP3 files work. There is no component built into VB.NET or the .NET Framework that'll do this for you. You'll need either DirectSound (in the DirectX SDK) or some other 3rd party library to do something like this. You can Google for "MP3 component .NET" for some suggestions.

Where in your app is this code? Is it in the OnPaint Event of your form?

In a Windows 2000 domain, is there a way for me to check the Users ID currently are login from which Computer name. Currently I am supporting users Computer from various Countries and at location in my company. I know the login Users ID but would not know from which Computer name they are login from. I am trying to write a program either using VB.Net or VB to see the user is currently login from which Computer. This will help me locate the users computer faster and more efficient for troubleshooting from remote. This program will likely to run from my Computer. Else I will have to guide the user how to find out thier Computer name or IP addresss. Or is there any alternative way to find out the Users ID login from which Computer name. Thanks

The legacy domains don't save such information, so finding it would be impossible.
In Active Directory, though, you can try the Network Address property, or the Last-Workstation property of the User object, though it is documented as "not used". Other than those properties, the information is not stored anywhere else.

I wonder if the original BASIC is an interpreted language, since the original BASIC uses an interpreter rather than a compiler.
Also, what is the extension of the BASIC file? (for example, .c is for C language, then what is BASIC's)
Okay, now, is Visual Basic an interpreted language or compiled language?
Thanks
-----------------------------
C++ without virtual functions is not OO. Programming with classes but without dynamic binding is called "object based", but not "object oriented".

IIRC from my Basic class ye so many years ago, the extension would be .bas
VB is now a compiled language.

Actually, the BASIC language predates Microsoft by 11 years. The BASIC programming language was developed in 1964 by John Kemeny and Thomas Kurtz.

When you said the original file extension was .bas that was the implication. I have used BASIC language implementations where that is not the case and they have been equally as old as Microsoft themselves.

Well, it WAS a long time ago(about 15 years or so), and I could remember writing those basic codes:
10 Do something
20 do something else
30 Run
in those dinky ancient apple machines. I could've sworn the extension was .bas but I'm probably mistaken.
So, what is the extension?

I don't know what the original file extension was or even if the OS supported file extensions, or if the original creators deemed it necessary to give a file extension way back in 1964.
The point I was making was that as you said "IIRC from my Basic class ye so many years ago" that you were unlikely to have used the first version of BASIC (I'm guessing your first BASIC class would have been when you were around 13 to 15 [most schools don't teach programming earlier], give-or-take a couple of years, so that would put that class around 1992-4. Or about 30 years after BASIC was invented.

Hello,
Currently I'm working on an application with a simple datastructure. That simple that I use XML as datasource for the tables. Now reading, changing, adding, deleting and writing to and from the xml files goes perfect.
However this app also needs to export text files with fixed width. Also that is working, even with xml based specifications for exporting (fieldname and startpositiong). The only thing is that I would like to query the dataset/datasource with a select statement and export this query instead of the table. How can I do this?
Thanks so much in advance.
