Open/Close Drive With The Single Button?
Feb 16, 2011
i am currently using this code to open and close my drive in VB. However i want to make a single button to open the drive if its close and to close it if its open.
Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal command As String, ByVal buffer As String, ByVal bufferSize As Int32, ByVal hwndCallback As IntPtr) As Int32
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim lRet As Long lRet = mciSendString("set CDAudio door open", vbNullString, 0, 0)
End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)HandlesButton2.Click
Dim lRet As Long lRet = mciSendString("set CDAudio door closed", vbNullString, 0, 0)

I'm making an equation program and I want to have a main menu where the user can select an equation and then when one of the buttons is clicked, it closes the "selection" form and opens the appropriate form. For now I just have it set to show the proper form (for example, Form3.Show) but when I try to do something like Me.Close() after it, everything closes instead of keeping Form3 open.

I am having a hard time with this. This is my code:
invoiceform.show()
me.close()
This is the only way I can think to do it, but it closes the application due to me.close(). How can I do this? Invoiceform is already running!

I've created a very simple form with one button on. I need it so when the form runs, it opens in the bottom right hand corner of the screen regardless of the resolution. It also needs to be always on top of all other applications.
When the buttons pressed, i need it to close all iexplore instances and reopen a fresh instance.
I've tried to search for the answer but to no avail.

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

First off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

how to open an .exe file from a that is in a certain file, what i am trying to do is create a program that will be portable-via jump drive or cd drive, the reason i feel stupid is that I did not realize that visual basic and vb.net are two different animals- I was trying to use app.path for days- then came across a post that set me straight that I can not use it.[code]

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

I know, looping through is fast enough. But the search program "Everything" can index my entire C: drive in about 15 seconds. Does it read the MFT or something? Can I do this easily enough with VB.NET? Or at all?

I'm trying to write a program that opens a folder from the CD disk when a button is clicked. The program will be run from a CD, and aims to open a certain folder. However, I can't use "shell "explorer...."" because the drive letter will change between different computers. Is there a way to open the folder straight from the CD in VB.NET

i was wondering if there is any way to read from a file in the application directory without specifying the drive letter. Here's what i have:Dim var var = My.Computer.FileSystem.ReadAllText("c:appdirectoryfilename")
If i leave off 'c:' it looks for it in system 32 or something. why can't i just say
ReadAllText("filename")

I have a form containing a date textbox and a submit button and a close window button. The date textbox onblur calls a javascript function which checks for date validation and some other logic and displays some alert messages. The date on the textbox is always selected and onfocus. My problem is when I try to click the close window button with/without changing the date the alert messages from the onblur logic are displaying and I am unable to close the window. I tried using onchange instead of onblur but onchange too works when a control looses focus. it works fine when I donot change the date but when I change the date and hit the close window button it too displays the alert messages and the window does not close. Please suggest me what will be my best option.

I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code:
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work
Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
