The client has asked in vb6, if we guys develop in VB.NET then there is no point that we are serving the clients with their requirements.
And i don't understand that what should be the best version of MDAC to be installed on the machine. I've the latest 2.8.
Mr.Eddy Vluggen I can see my component in COM, still do I need to register my component with 'regsvr32' ?

You mentioned VS2010; sounds like you are already developing in .NET - what language is the component written in? And yes, I expect you to understand "why" the client proposes the requirement, as opposed to simply agreeing. Keep in mind that you're the programmer, you are the one who knows what the language-choice implicates, and YOU are the one responsible for using it.

Yes. You need to register your .NET control before you can use it in VB6.
That goes for all ActiveX controls.

crieterion is to develop a component. We have done everything and sent to them..
After few days, all of a sudden he said he want the component to be used in vb6 applications.
Thank you for your suggestions !! 
But my component is not registering with regsvr32.exe

I believe it's regasm[^], not regsvr. I tend to confuse them often; it's easier to search codeproject[^] for an article that has the procedure than it is to remember it after not using it for a few years. The CP-article shows all required steps, including registering.

Its working a bit now. 
But error giving some error, i'll try to get rid of it.
Thanks Eddy Vluggen.

The component is in C#.NET in VS2010

Private Sub btnHostTools_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHostTools.Click
If GameActive Then
frmHostTools.Visible = True
Else
MsgBox("Please launch halo first!")
End If
End Sub
My problem is when the game isn't active it displays the message as it should, but the problem is that when the game does become active it will automatically show the form if you clicked the button when it was inactive.
How do I make it stop doing this, it's VERY annoying.

Disable[^] the button when it shouldn't be active. That way it won't be able to receive input (-focus).

I have a table with student info.
It is possible for the user to enter the some
student 2 or 3 times, even if the studentId (primary Key) maybe diffirent. the first name, last name, classe ect may be the same.
If I have a student that have the same 6 fields the same I want to automatically delete them form the table remember the Student is set to auto increment.
thanks in advance

This may be true in your applications, but not in mine. If you're running into this, you did something very wrong, or not at all, during validation and data integrity checking before you wrote the record to the database.
Oh, you didn't check for duplicate data entered before you added the record?? Huh, that would explain why you've got this problem now, wouldn't it?

Normalize your dataset; if an autonumber-key would solve all those structural problems, Access would have been a first-class development environment.

The same advice applies; normalize your dataset to PREVENT this from happening in the first place.
Google for "SQL remove duplicates".

There is a article in here that has a class that puts a wrapper around "Lame.exe" so you can use Lame to convert .wav files to .mp3. It works great, but I cannot seem to get it to loop through a directory and convert all files in that directory. Does anyone know how to do it with this method, or have another way of doing it?
|
|
|
|
|
Do you use this:
VB.NET LameMP3 Shell[^]?
If so you would have to create a new instance of your converter for each file you are trying to convert. WAV to MP3 is quite math heavy to do, so I'd guess it would take quite a while to complete the convertion...
|
|
|
|
|
I do use that. Can you help me with a little example of what you mean? Also, do you know a easier way to do it, or do you think this is the best?
|
|

|

Use the Directory.GetFiles[^] method. There's an example on the same page on how to use it.
Call your convert-method foreach item that you encounter.

I like forking, and I don't mind the overhead compared to a thread. No, it's not the "best" way, because it'll be hard to display some progress, the user might think that your software is "stuck" somewhere and decide to terminate it.

What do you mean by "forking"? I am kind of new to programming, so please excuse my ignorance. I got the code to work, but like you said it seems to "hang". I also noticed that there are about 20 or so instances of "lame.exe" running in the task manager, so the machine becomes very slow and sluggish.

iismoove wrote: What do you mean by "forking"?
Applications sometimes do multiple stuff at once; in that case you often need threading. I'm more of a fan of "forking", where one runs an executable and fetches the result. An independent executable can be tested without the rest of the crap, makes maintenance a bit easier.
iismoove wrote: I also noticed that there are about 20 or so instances of "lame.exe" running in the task manager
Aight, that means it works. It's best not to start all 20 conversions at once, but one after another. You're probably using the Process class to launch those, and you'd have to wait after launching until it is done before moving on to the next one.
Call the Process.WaitForExit[^] method in your loop to block execution until the external application finishes.

I am using LameShell from Qualtar. I was looking through it, because i think that just has
Process.Start instead of waitforexit(). In the LameReader function there is a _lameProcess.Start() and I tried to change it to _lameProcess.WaitForExit, but then i get a error that there is no process.
|
|
|
|
|
Aw, that means that you'll probably have to modify the lame-code. The Process.Start function returns an object of the class "Process"; you'd call the WaitForExit method on that object. Something similar to the code below;
Dim p as Process = Process.Start("Notepad")
p.WaitForExit()
Hope it works

Seems it's executed on it's own thread. Making a blocking version wouldn't be that difficult, but your app would seem to "hang" until the process is actually finished. This is "the better" version, although it makes it a bit more complicated to use.
As opposed to looping and starting all the conversions, it might be better to make a list of all the files that you need to process.
Dim items As List(Of String) = Directory.GetFiles(..
Start the conversion with the first item from the list, and proceed to the next one once the Done-event of the LameShell-class is raised. That way the code needn't block anything, keeping your app nicely responsive
