Create A Virtual Piano Using Pictureboxes To Represent Keys That Play .wav File Versions Of Notes
Nov 5, 2011
I'm trying to create a virtual piano using pictureboxes to represent keys that play .wav file versions of notes. I've gotten this to work fine; however, I'm having trouble with two features I want to implement.The first feature is to be able to save what I play in a text file. I thought I could use this code but I'm getting an error. [code] The second feature is to play random keys using the random class. Is there any way I could store the pictureboxes in an array and then use the random class?
i am trying to make a virtual piano.in that i am also playing music files which is recorded through the above said piano.but how can i understand when this music playback ends.i need to invoke another function when the plyback ends.so how can i understand when the playback end.
I'm pondering a design that will require zooming. My intention was to use pictureboxes to represent a variety of items, and I have the code written to draw on those pictureboxes, as needed. However, there will be many pictureboxes on the form at any one time, though only a portion of them will be visible. That shouldn't be a problem, necessarily, as there isn't any issue with having controls that are not on the visible area of the screen. My issue is that when the user rolls the mouse wheel forward or back, the image will have to scroll in or out, which means that the location and size of the pictureboxes will have to scale relative to the point where the mouse is located.
Technically, this would be more easily accomplished using graphics directly, since I can use ScaleTransforms and...uh...one other, to do the scaling. However, I would prefer to stick with the pictureboxes because I will be doing lots of drag and drop work with them (dragging things into and out of them), and that code is already written. If I were to change that to use rectangles and circles drawn dynamically and scaled dynamically, I'd have to use some kind of hit testing to figure out which object I dragged or dropped onto, and where. Therefore, switching away from pictureboxes would require a fair amount of recoding. There really shouldn't be a problem scaling and translating the controls on the form, but rather than writing the math behind that, I was wondering if there were any built-in tools that will do it for me or will help with the process.
I have problem to play the piano swf inside the TabControl1 (WebBrowserA), but i can play piano swf within the main form (WebBrowserB). Anyone know why, and the method to solve it to play at tabcontrol1
To the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.
I've been trying make a mdi notepad that can start up new instances of a "note" which is unique from the other notes as in you can save/change/cut/ copy/ paste in the individual notes without changing the properties of the other notes..something like a tabbed notepad but instead of tab control i have a mdi container. but i can't make it work. [code] problem with it is that whatever you cut/copy/paste in one mdi container richtextbox, it automatically cuts/copies/pastes in the other richtextbox controls in the other containers..
Is there something like a doc.GETITEMVALUE("Attachment")(0) ?Also, I can't find any documentation for the domino API. Does anyone have a good resource for this?

Im trying to open media player (full screen) and play a movie. When i create the file path like so: Dim MoviePathVTS As String = String.Concat("""" + tempMoviePath, " \VIDEO_TS\VTS_01_1.VOB" + """")
It wont play the file but if i do it like this: Dim video1 = """F:\Movies\DvD\Angels and Deamons\VIDEO_TS\VTS_01_1.VOB"""
It plays fine? the file paths are the same including the extra "" but it just refuses to play. I need the top one because i have many movies in a treeview.
Heres my code
Private Sub watchNow_Click(ByVal sender As Object, ByVal e As EventArgs)
'get the position of the selected node Dim i = movieTreeView.SelectedNode.Index
I want to create virtual directory using vb.net. But while creating permission denied error occurs.If im manually creating virtual directory no error..
As part of my current project for making student's lives easier by making an All-In-One application with many common programs carbon-copied inside it, I have a slight problem with sticky notes.
I am trying to recreate Sticky Notes as much as possible from the Windows 7 Sticky Notes Application. My problem is, I put a richtextbox on the sticky notes panel and wanted to either add a background image, or a transparent backcolor (my Panel that the textbox is in has the background image of the themed sticky notes). So my question is, is it possible to somehow dynamically make a property to allow the backcolor of a richtextbox to be transparent? or allow a background image?If you find an answer helpful, click the Helpful button.

My project is to create a virtual operating system in BENGALI through VB. I have created a virtual desktop in which there will be icons such as MY COMPUTER, MY DOCUMENTS, RECYCLE BIN, INTERNET EXPLORER... The internet explorer icon has been linked to the original internet explorer, as the case in RECYCLE BIN. But i am not able to connect to MY COMPUTER AND MY DOCUMENTS. Also in creating the START MENU, there is a RUN COMMAND........
Basically here is my problem. I have a software program that needs to 'print' a file before it will save it. I want to be able to print to my shredder so that it saves the document, but I don't actually want the document printed. So I need to print to a program that securely deletes the document and shows as a driver in Windows.
What I want to do is use one PC to test an application on another on the same 19.2.168.X.X.I would like to make it seem like SOAP requests are coming from a variety of different PCs, just to make the applciations log file easier to read and I have been told that virtual IP Addresses are the way to go. So, how do I defien a range and then use them one by one in VB? (I guss that this is effectively IP header spooging?)
I create multiple dynamic pictureboxes and it are to many to add them all manually, is there a way I can e.g. use an integer which adds up every time a new picturebox is made. Then I want to add the same code to every picturebox. Now it creates the picturebox and moves it to the next spot and doesn't create a second. I am using this code if its helpfull:
Using the code below I can create multiple pictureboxes dynamically on a form. What I can't figure out how to do is determine when the user selects one by clicking on it. If I use mousedown events I have to hard code in the subroutine the name of the picturebox, which I don't know until the user selects it.
Private Sub AddNewPictureToolStripMenuItem_Click(ByVal sender As System.Object,
I am doing a data migration from Lotus notes to another type of software that does not support Rich Text Fields.I am trying to write a VB 2005 program that will take any rich text fields that are found and place them into an RTF file - which will be uploaded as an attachment in the new software.I cannot get the program to take the rich text formating or objects to the RTF file, only the plain text.I have tried everything under the sun using the COM library to get these objects out to no avail.

I have create a Data base in Microsoft Office Access 2007, and I want to make the same databse in Visual Basic 2005 Express, but the problem now is the Invoice form, it must have a form with subform to represent two deffernt tables or query?
I've read about revising the File Version (and Assembly Version) to ensure that an updated file does replace an older/previous file when a WI update installation is carried out, but I don't understand the four-part construction of the File Version ... and my re-versioned files sometimes refuse to transfer to the target computer.
For example, a .exe I have recently updated had it's File Version set to 1.0.0.0 (it is resident now in my Program Files (x86)/MyApplication folder) and File Date 23/03/2012, but even now with the File Version set to 2.0.0.10 and a File Date of 24/03/2012 when I use WI to install the new program over the original the 1.0.0.0 file remains in place and the new 2.0.0.10 file does not get installed instead.
"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim obj1 As New Invoice(Val(TextBox1.Text)) TextBox1.Text &= obj1.Invoice1 & vbNewLine TextBox1.Text &= obj1.Invoice2 & vbNewLine TextBox1.Text &= obj1.Invoice3 & vbNewLine TextBox1.Text &= obj1.Invoice4 & vbNewLine
i want to know if you can save pictureboxes into a bin file and load them in? Here is a basic code i wrote up that did not work. If you tryed and cannot save pictureboxes as a bin file please suggest another way. But if it is xml dont bother to tell me. I went down that path and left. It was to hard and did not work.
I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I've been trying to find a Windows API function I can use to generate a virtual file handle in Windows. I'm working with VPC/xVM and I want to create a virtual machine that actually points to my physical hard drive - the methods provided with VPC and xVM for this really suck (I've never been able to get it to work with either virtualization product).
I'm working on an asp.net project which has a form with a file attachment capability. Since I'm uploading the form on a server, I can't use a physical path. How do I use the asp:FileUpload with a virtual path?
I'm trying to make a program that can mount a file associated with the program as a virtual drive such as PGP does. Encryption isn't necessary to the program, but if it is needed to mount the file as a virtual drive then so be it.
If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.
