I play a midi file using this simple win32 api call:
MidiMsg = "open " & c_midiFile & " type sequencer alias mid1 notify" ret = mciSendString(MidiMsg, "", 0, Form1.Handle) MidiMsg = "play mid1" ret = mciSendString("play mid1", "", 0, Form1.Handle)
Callback message MM_MCINOTIFY has a value of &H3B9 (found it using "spy++")I have to know when this message (MM_MCINOTIFY) is fired and read his parameters. In an old version of code I've written years ago in VB6 i had to use CallWindowProc and SetWindowLong win32 api, but now in VS2005 i cannot get it to work.Still I have to try with unmanaged code or are there any other ways to do this in vb .net?
I think that my previous post wasn't what I should have been asking. I think my issue has to do with Convert.ToString in my code I have this 3 times, I have no errors while writing the code, only when I debug it I get the error message "input string was not in correct format"
I am writing a program in VB express 2008 which I want to be able to receive input from an xbox controller as well as activate the rumble on the controller. I am using the XBCD drivers for the controller [URL].Basically I want to say "the further forward the thumbstick is pushed the more the controller should vibrate".
I'm working on a project where I have to send data to the serial port through a radio modem onto a servo controller. Everything works fine but since I use a timer to detect joystick changes (directX). Even if I don't touch the joystick, because of the timer it still sends data thru which is killing my battery on the receiver side.
I've been using DirectX SDK libraries (Specificaly DirectInput) to use a joystick with an desktop program, but I haven't been able to make the program get the input form the joystick (X and Y Axis). This is the code I'm using on Main Form:
When I plug in the USB joystick, I'll have to go to the control panel and select game controllers. I click on the properties and a pop-up is displayed. On the top left hand corner of it, there's this small square 'picture' with a plus sign at the middle indicating the joysticks' movement. As I moved up, the sign moves up as well and as I move down it does too. It depicts the movements of the joystick in use.
I was wondering how to code the exact same thing as I'm planning to place the square thingy in a 'question' image which will change after every submitted answer of the image using the joystick.
i want to read the joystick input?is it somewhat like keyboard input?
Private Sub form1_keydown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown Select Case e.KeyValue Case Keys.Right TrackBar1.Value = TrackBar1.Value + 1
I have two arrays which I am graphing. I want to use VB to calculate the slope and intercept of the resulting graph. I'm using the Analysis.Math function of measurement studio. Here is what I have so far.
data_array(logtimes, 2) = temp data_array(logtimes, 3) = log Dim slope1 As Double
I want to be able to intercept a print request and then check whether the current user of the computer has enough credit to print. So once the request is intercepted i want to check the total number of pages requested and check against a database how many pages this user is allocated to print, if the total number to print exceeds the number in the database then cancel the print job and notify the user
Is there a way to intercept POST data like HTTPAnalyzer?Can I make a call to send the data, see how it's formatted but actually block the connection if I know where it's coming from? My goal here is to replicate the sending of an email through an SMTP server.
This is not a programming question but a physics one.I was wondering if anyone has a link that good give me the math for two objects: one moving and the other intercepting. Specifically, I need to determine the vectors of the pursuing object when given the vectors of the object he is trying to pursue.This is classic video game programming and in my instance it's supposed to be a football player running with the ball being chased by a tackler.The code I have now determines where the tackler should go at one particular instant, but does not project where he should be in order to lead the target.What happens is the tackler runs behind the ball carrier - he doesn't cut him off.It's like if a QB throws the ball to where his receiver is instead of in front of him; when the ball arrives the receiver is long gone.
I am looking for a way to possibly intercept the point that a file is being accessed on a network share. Specifically before it is determined whether the user has access to the file or not.The goal will be to grant access to that file if the file request is coming from a specific process and that user currently does not have access.
I have a VB 6 SP6 application that uses DirectX 7 to interface to a USB joystick (Logitech Extreme 3D Pro).The application works under Windows XP Pro (32-bit).I've got Visual Studio and the application running under Windows 7 Pro SP1 (32-bit).
I've calibrated the joystick under Windows 7.The VB 6 application does not find any DirectX 7 joystick device to connect to.Otherwise, the VB 6 application works (GUI, embedded video, serial channel, Ethernet connections).The VB 6 application must be accessing the dx7vb.dll or it would crash.The joystick disc did not provide a driver.I installed the latest joystick Profiler vendor software from the Web.This is my first attempt to use Windows 7 as a platform.I'm not sure what to try from a Windows 7 perspective.
I am learning Visual Basic 2008. I have created a form with a datagridview bound to a dataset. I also added a button to the datagridview. When the button is clicked I want to be able to update a couple fields in the grid with new values. How do I intercept the click of that button?
I have made a small program that reads the input of a joystick/GamePad and passes it on to a serial port. It works great I can see all the buttons pressed ect ( in a textbox). But When I minimize the form and press some buttons they are no longer passed on to the serial port and not shown into the textbox?
When a user clicks on the little red "x" a.k.a. the form close button on the form command bar, what even is activated besides FormClosed()
I know FormClosing() is called, but I cannot really stop the form from closing after my code is run. I want to be able to show a messagebox that asks if the user wants to exit the form or not. Obviously if they click no, I want the form to stay open, how would I do this?
This may seem complicated but it's a somewhat basic concept, just probably a complicated execution, I am trying to create a program that will allow you to basically "IM" between computers on a LAN network. That's the concept, I plan on doing this by generating .bat files, executing them and printing the last few messages sent in a label, the big problem I have is receiving messages, I have no idea whatsoever how to even go about finding out how to take the messages received from the messenger service and print them into the label, any ideas?EDIT: This is in VB.Net 2008
What I am trying to do now is design a program that will play 4 different sound files depending on the position of a joystick. I am not looking for any kind of gradient to be involved. Any kind of forward position should play the file associated with "forward". Any kind of left position should play the file associated with "left". And the same for "back" and "right".
I have only started using VB yesterday and have managed to make some very basic programs run. What I am trying to do now is design a program that will play 4 different sound files depending on the position of a joystick. I am not looking for any kind of gradient to be involved. Any kind of forward position should play the file associated with "forward". Any kind of left position should play the file associated with "left". And the same for "back" and "right".
I use DirectInput to control a joystick. Now I use a timer to continuously runs a sub Private Sub timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick UpdateUI() End Sub Public Sub UpdateUI() ' This function updated the UI with ' Joystick state information. [Code] .....
The problem is this is not very efficient. Now I would like to know if its possible to trigger a sub as soon a button D-sub of analog stick is pressed/moved. I've seen the following: [URL] How to implement this?
For my webbrowser application I would like to have a separate form to display online pdf files.Does anyone know how I would check to see if a clicked page link points to a pdf file and if so open form3 and load the file into the pdf reader component (pdfread) without causing the webbrowser to navigate to the link, this always seems to open the pdf file in a new instance of internet explorer.
I realise that to load the file into the pdf reader the code would be
pdfread.loadfile(whatever file)Hope I've explained this properly.
