First of all, you can interface VB (and C#) with Excel, and you can find plenty of examples on how to do this. So I will not attempt to address that, since if you don't know VB you are going to be spending lots of time with that part to begin with.
Now, for the PDF part. I have many, many words in my vocabulary to describe working with the PDF format. And when I am actually in the process of working with PDF, I use them all, constantly, strung together in novel creative ways. For the sake of the forum let me just summarize as "major hassle".
There is an open source library that is invaluable when working with PDF's although depsite the fact that I consider it essential, working with this library can also be described as "major hassle".
Although the library, and most of the documentation is for C#, you can use it in VB.NET as well. (Despite some arrogant misconceptions otherwise, C# and VB.NET are really the same thing).
You'll find a lot more examples of interfacing to Excel in VB. You'll find working with the PDF library just damn difficult no matter which way you go. Assuming you do not know either VB.NET or C#, the choice is really up to you.
Let me say in no uncertain terms, this project was handed off to you for GOOD reason. It could take you months to figure it all out.
I strongly, strongly, strongly advise you to punt if it is at all possible. Really. Punt! Punt! Punt! If you can't punt, find a shady doctor that writes shady 'scripts and tell him you need speed and valium. Both in large quantities.
You can find the PDF lib here:

I feel for you.

You'd find a couple dozen examples of this, using a few different methods, by typing "vb6 record sound" into Google. Or, just click this[^].

Shell launch it using the Process[^]and ProcessStartInfo[^] classes. Just make sure you use the full path to the .PDF file your trying to open.

How can I make sure that ALL forms in an application close when the user exits the program?
My application consists of multiple forms and I use form.hide() which (I think) is leaving any previously viewed form in memory.
On the Exit command I use Application.Exit()but I don’t think that all forms are being cleared from memory and the computer still thinks that my application is running.
Thanks

Not true. All the managed objects you create are destroyed when the startup form is destroyed. The problem comes in when you don't release unmanaged resources, like file handles, GDI handles, various COM objects, ...

Hi everybody
I' got a problem. I need to get excel comment notes from a cell. I found some examples on the net talking about use somenthing like this: 1) "....Range(a_range).Comment.Text" -> this method also generates an error if the range doesn't have any comment note but if it do then it works; 2) "....Range(a_range).NoteText". They both works good under VBA but under VB are not working properly. Any idea of what's wrong with that?
Thanks!

Hi
I have developed a windows service in VB.NET. The service is checking a folder for any files that have been created and then needs to launch an application (GUI). The service is working, but I need help on launching the application. When I step in debug in the service, the program steps through the code, but the application I'm try to launch doesn't load. When I use this same code in a normal application, it is working. Can anybody please help me? Is it possible to do this?
Thanks,
Chris

This question always come up when someone tries to write a Windows Service but has no idea how they really work.
Services run at Windows startup, not at user login. But, like any other application, they, too, must login to Windows, just like any other user, so they can get a security token and have permissions to various system resources. Windows Services, by default, run under a Local System account, but can be changed to run under any user account specifically setup for that service. For instance, by default, IIS runs a site under the ASPNET account that created for it.
Also, services have their own desktop, not the visible one you see as a user. There is no way to "flip" between the visible and invisible desktops either, so don't get any ideas.
In order for the service to be able to interact with the user's visible desktop you have to go into the Windows Services Manager and change the properties of your service to allow interaction with the logged-in user desktop. This is only possible if the service is running under the Local System account though.
Right-click "My Computer", then click "Manage". In the left pane of the window that comes up double-click "Services and Applications", then click on "Services". In the right-side pane, find your service and double-click it. Click on the "LogOn" tab of the Properties dialog that comes up. Make sure that "Local System account" is selected, then make sure the "Allow service to interact with desktop" checkbox is checked. Click OK. That's it!
Your service should now be able to create a new process and have it show up on the desktop.

I want to enable TCP\IP protocol, for my client server application, at server side. Becoz i m using MSDE as database. I can enable it through by using SvrNetcn.exe, but i want to enable it by vb.net code or by command line or any other way with out using any User Interface. How i can do that?

Considering that you only enable TCPIP in MSDE once and leave it, why go through the hassle of coding it yourself? Just shell launch the thing with the proper command line parameters to do the configuration for you if you really have the need to do this.

I have no idea how it's done by that utility. There is also no documentation anywhere that describes how this utility works, that I could find anyway. Since there is a .DLL by the same name, I would guess that all the functions requires to do the work would be in that .DLL. But finding out what the functions are, how they work, and what parameters to pass to them will be VERY difficult.
In short, I don't think you'll find what your looking for.

How to create excel file in VB
plz help me

What do you mean? Create an empty xyx.xls file with an Excel format?
If that's the case you have to add the Office reference to your project and use that object. If you browse through it's classes you'll see methods for creating and saving files.
