I want to select either "Wave" or "What U Hear" or "Microphone" or "Analog Mix" (LineIn) in the Windows Recording Control applet, i.e. as if I clicked the applicable "Select" checkbox.
I got this VB6 code on the Net (not sure where) and tried to convert it to VB2008. It is very near to correct I think, but the last part does not work.
I was just wondering if anyone knows of any free Open Source software wich demonstrates multitrack recording support? I was thinking of something in the lines of this: [URL] I want to include multitrack support in my own software, for personal use and I don't even know where to start to be able to do that. So preferrably a control or something would have been great. I could also be able to pay for something like this, as long as I'd be able to include it in my own VB.NET solution. Edit: What's with the vote down? I was just wondering if there are any components I can buy and download to use in my own project..

View 2 RepliesWe are trying to modify a program to control a usb relay device. Essentially what the program originally does is give you a series of check boxes that you check to make the relay fire. We tried to modify the code so that the box is checked after 5 seconds using a counter and an if statement. It works, but only partially, what happens is the check box shows a check, but the even that is normally triggered does not happen. [code]

I am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.

View 2 RepliesI have read this many times. Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms. What exactly is the difference?

View 2 Repliesi recently downloaded a demo game "Delta Force Xtreme 2 BETA". the game it's self, looks like vb3 does when compared to vb.net 2oo8.. one thing about it, on the startup screen, it plays a decent track of music..
i want to record that sound, in wav format, i guess, directly from my speakers. i googled all day, hoping to learn something about playing/recording sound, and i got nowhere.. so i finally decided to post here, after searching the forum for answers, again, without any luck..
i'm not looking for links to sites that the code is not tested before the link is posted.
just a form with 3 buttons. 1 to record, 2 to stop and save, and 3 to play. again, the sound should be recorded directly from the speakers.
I'm working on a function that handles events from a number of buttons and trying to define a Select...Case based on the clicked button. Something like this...
Private Sub btnClick(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles btnThis.Click, _
btnThat.Click, _
[Code]....
which don't work either. Is there any way I can define a Select...Case in this manner or is it always destined to fail due to the attempt at comparison of reference types?
Can a listview multiselect in the same way as a listbox can, when it is set to electionMode = multiSimple?for instance when the listbox is set to selectionMode = multiSimpleyou can just select any number of items in the listbut...with a listview you can only multi-select when you hold down Ctrl. As soon as you lift the Ctrl key and click on an item it de-selects everything and only selects the last one you selected

View 1 RepliesAm new to the VB platform and have only been messing around with 2008 for a few months,off and on.Have built a rotational inertia based Dynamometer for personal use in my R/C hobby.Have written some code that allows me to read roller frequency,that is then figured to roller RPM,and eventually ,vehicle ground speed.
Now before anyone shoots me down,( I don't mean this to be sarcastic,but I have received negativity on other forums) I know that ,because of various interupts on my P.C.,that the windows timers aren't all that accurate,causing me to miss incoming signals that screw up my measurements, and the best thing is an external aquisition unit.Let me just say that I run my VB program parallel to an external frequency counter,and have at any given time a difference of max. 8 hz at higher revs.Also I use an external timer based counter that figures the ground speed ,and it also is within a half KmH.This is only a hobby for me and that's close enough.Someday I may build something that does the computing externally and gives it to VB,but for now.........So now to the good part
Here's my question: How can I write code that will let me record the RPM ,from TextBox2, at each timer interval,and have them listed?
I need this to calculate the RPM changes per interval in order to establish "angular acceleration" ,for further calculations.
In Addition,I need a way for my program to know when something changes or does'nt.If I start my programm and don't run the dyno ( no signals) then it will start saving a bunch of zero's that I don't need,and when I get to the end of the run,the RPM will top off(no change in signals)but keep saving.The best would be,start recording when the 1st signal is detected and stop recording when the signals stop changing, and tell me I can stop.
But I'm not that advanced.........yet.
The next problem is that I have no idea,depending on what vehicle I test, how many intervals will be recorded, as one may or may not take longer to reach max.RPM.
Heres what I have so far:
Public Class Form1
Dim product1 As Double
Dim product2 As Double
