I need to make a program for school that closes the active window. My application does now SendKeys.Send("%{F4}"). It works but, it also does it when there are no active windows. I want it to close only the active windows.

View 9 RepliesI have to make a visual basic program for a school assignment. I am an absolute beginner at it though, but am willing to learn.I have to make an income calculator for farmers that make giant turnips.
So basically:
1. If the turnip weighs less than 350kg, the farmer will receive $2 per kilo
2. If the turnip weighs 390 or more, the farmer gets $1.50 per kilo MINUS $180 for a maintenance fee.
3. If the turnip weighs between 350 and 389kg, it has to be sent to a paddock that costs $25 per week for lease. Turnips loose 1% of their mass per week in this paddock. When the turnip gets below 350kg it can be exported. As ships depart weekly, turnips may drop a bit below 350Kg before departure.
Create a profit calculator for the turnip farmer for a list of cattle weights.
Functional Requirements: oEnter the weight of each cow into an array oCalculate the income from each cow and store in another array oAdd up the values in the array and display total income.

View 7 RepliesDoes anybody know if it's possible to make your program 'self-destruct' (delete itself) when it closes? I know this sounds like malware, but it's not. What happens is the user clicks 'install', the application copies itself to another directory, then the application starts the new copied file, with an argument that begins the installation, kills itself, and then the copied application restarts and then it's done. But I can't get rid of the original executable.
View 13 RepliesI'm using Visual Basic 2010 Express.I have a form that can be minimized.There's also a tray icon.I've coded it so that if you double-click on the tray icon, the form's FormWindowState becomes set to Normal; this restores the form to where was before it became minimized, but the form does not become the active window on my desktop.
How can I make the form become the active most foreground window? I've tried various functions that I can think of but no luck yet. Tried searching with various queries to try and find the right wording but no luck.I'm new to Visual Basic - only started a couple hours ago.Probably something simple but I can't seem to find the correct function or anything.I have the form/window open, and then I overlap said form with a window of another application. When I double-click my app's tray icon, I want my window to become the active window, bringing it to the front, but can't figure out how

View 1 RepliesI have a VB program that displays a PDF file. When the program is closed it takes 30 seconds or so before AcroRd32 process releases the PDF file. In certain circumstances if the program is restarted with in this period, the PDF file does not display. The specific circumstances is that I have a second program (re)starting the program that displays the PDF file.
a) Make the PDF file be immediately released when my program closes
b) When the PDF file is loaded test that it properly loaded so that it can be reloaded if necessary.

View 9 RepliesWithin my Visual Studio 2008 VB.Net project I am opening multiple forms after setting the form (that is opening) to be an mdichild of the main form. This works in really well in most of my forms except one. I am doing the exact same thing for all of them.
Basically I declare the new form:
Using frm As New frmName() With {.variableName = currentVariable}
frm.MdiParent = Me.MdiParent
frm.openForm()
End Using
Within the openForm subroutine in the form code I have:
Public Sub openForm()
InitializeDataSources()
... ...
Me.Show()
End Sub
I know this works because if I remove frm.MdiParent = Me.MdiParent in the main form and change Me.Show() to Me.ShowDialog() in the child form then it works perfectly. Right now (for only one form) it shows the form for only a second (looks like a flicker when staring at the program) and then closes it.

View 24 RepliesI am creating a window that is a generic keypad for editing numerical values on a touchscreen. I would like to press an 'edit' button to create a copy of the keypad window/bring up a reusable version of the same window (I don't care), but pass in parameters: the old value I'm manipulating, and a title to be displayed above the number pad. I would like the user to be able to type in the new value, then press the 'done' key to submit this value and have it sent back to the main application window into my custom control that contains a text box.(I have the number pad's layout sorted out already; I'm already using a variation on it to set a global password 'access level'. It's getting the information in and out that has me scratching my head.) [code]
View 1 RepliesI am currently working on a launcher, and it must consist of the following:
- one main routine being called, NO WINDOW may be created at any times after or before this main routine.
- one small form called by the main routine if a certain command was sent through the Command (shortcut).
At this point I use a Windows Form, but it seems a little useless to create and initialize a form if you won't even use it. Any way to make a routine run when my program starts without showing any window? But still make it possible to show that small dialog?
I did this at first but it seems a bit dangerous:
'NOTE: The following procedure is required by the Windows Form Designer 'It can be modified using the Windows Form Designer. 'Do not modify it using the code editor.
<System.Diagnostics.DebuggerStepThrough()> _
Private Sub InitializeComponent()
Main()
End Sub
Sub Main()
'Code to run here
End Sub
It starts another program (process) which has a GUI, so I do not want to display a console window.

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
I have so far been able to write the program that glasses the windows I want (via a global keyboard shortcut).
