If a form is being displayed on the secondary monitor, is there a way to make sure that a MessageBox generated by that form will display back on the primary monitor? The form is being displayed over a projection system and some messages do not need to be seen by the audience, just the computer operator.
View 1 RepliesI just got this really cool 9" monitor (USB attached) which I will be using for dialogs in my vb application. Can someone tell me why this code displays on both machines? if I change screen=AllScreens(1) to (2) the form is only shown on the primary but I want to show it on the very cool USB screen.

I am working on a custom bulletin board system for my company. The idea is to have a program running that displays a full screen bulletin board on many monitors around our facility. I wrote a VB client that pulls from a server and displays a single board perfectly - I am wondering how to expand this.

I have been writing visual basic and vb .net applications for years and have come across this problem with the timer component under Windows 7 32bit on dual core Intel processors. This problem only occurs with Windows 7 running on a dual core processor, single core and under the virtual pc on any processor works.
I have attached a test program to show this problem. The program uses 2 timers to count down to 0. It does not matter what type of timer component I use system.timer.timer or system.windows.forms.timer. I read the system.timer.timer may fix this problem so I changed the program to use it but it did the exact same thing. Left it in anyway.
The program: Timer1 is set to a number of ms for a given amount of time say 150000 for 150 seconds and started. The timer will expire correctly. At the same time a second timer Timer2 is set to 1000 ms for a count down display to 0. Timer2 fires and the count is updated. This happens and everything looks fine. When Timer1 fires I disable timer2 so it will stop counting down. Timer2's countdown is at 2 instead of 0. It is firing slow. If I increase the value of timer1 to say 500 seconds timer2 is behind by 6 seconds. These amounts are the same for the 2 very different computers I ran this on but both are dual processor systems running Windows 7. The exact code works correctly on Windows Xp on the same processors and works under Windows 7 on a Pentium 4 system.

My app displays a list of records in a DataGridView on the main form. I've developed code for cut/copy/paste for the selected records and have put the code behind Cut/Copy/Paste menu items under a classic 'Edit' menu design, with the standard shortcut keys(Ctrl + X, Ctrl + C, Ctrl + V).
The trouble is, I also want the shortcut keys to work on selected text when I'm editing inside text fields on a record in the DataGridView. So I need the shortcut behaviour to change depending on whether I'm editing a record or selecting record(s).
I have a form1 and many other sub forms in my software.I want all those forms to work on a 2nd monitor (if the user does have a 2nd monitor)while working on my 1st monitor as well.But i don't have 2 monitors in my system hence i cant test this feature out.But dual monitor integration is a very important part of my software.

View 2 RepliesI need a 2-listbox mover/selection type control such as the example here: [URL] For over a week now I've searched countless forums and done myriads of googles. All I've been able to find is C++ or ASP based stuff. I really would like this to be VB.net, but at this point, I'd even settle for C#.
I've taken a shot at developing it myself, but am too new to the .Net world to really get anywhere with it other than being completely overwhelmed and frustrated. I've even looked at some 3rd party custom control webistes, and am even willing to spend a few bucks for this thing, if I could find one that suits my needs.

I've got a dual monitor setup, my main monitor is a Dell 20" 1680x1050 res, secondary is a Dell 17" 1280x1024.I've just updated my gfx driver (nvidia driver version 190.62).I'm using code like that shown below to get the screens and I always assumed that AllScreens(0) would be the primary screen and AllScreens(1) would be the secondary but this appears to be reversed since I updated my driver.

Is my coding in error or is Windows reporting the screen information wrongly ? How can I be sure to set AllScreen(0) as the users primary screen and AllScreens(1) as their secondary ?

View 2 RepliesAfter I upgraded from Windows Xp to Windows 7 on any dual core cpu machine my programs that use a simple timer function run incorrectly. The program works with the exact same hardware under Windows Xp and Windows Server 2003. I am using Visual Studio 2005 to write .NET Visual Basic programs that use 2 timers to count down. The first timer, timer1, is set to a value say 150000 ms (150 seconds). The second timer, timer2, is set to 1000ms (1 second). Both timers are enabled one right after the other from a button click event and begin. The timer2 routine running every second updates a label counting down the seconds. When timer1 fires it disables itself and exits. Timer2 also checks to see if timer1 is still running if it is not it will stop. Under Windows Xp and Windows Server 2003 the resulting count in the label is 0 when timer2 detects timer1 has finished. Under Windows 7 when timer1 stops timer2 is not at 0 it is 3 for 150 seconds and gets larger the more timer1 is increased. It appears to me timer2 is not being fired every 1000ms as it was under Windows Xp.
I have included the Visual Basic code below. If you want to test it just run Visual Studio and create a new project. Put the buttons, numericupdown, and labels in your form and past my code into the correct buttons. I have used these type of timer events for years without any problems unit Windows 7. Windows 7 on a single core Pentium 4 with hyperthreading turned on works fine. Windows 7 on a dual core E6500 fails, Windows Server 2003 works.

I try to create a dual video player with VB 2010.
With that I have 2 forms, 1 main form (with all the controls and it should contain a preview screen of what is being displayed on the second form.
And a second form (with a windows media player component).
Now the main form should have (as told) a preview screen of what is shown on the second screen, I want to know if it is possible to have is as the windows 7 taskbar thumbnail (when preview the mediaplayer).
I have a dual-monitor setup. When I launch the main program, I need to make sure that it always launches in "Screen 1". I have a button within the program that launches another fullscreen window and I need this to always launch in the next available screen (read: not covering the main program window)I am using the System.Windows.Forms.Screen class to try to accomplish this and have have had about 80% success. I can successfully test for multiple monitors (which enables the button). When they click it, I can get it to always launch in the second screen. The problem I'm encountering while testing is the main program is launching in Screen 2, so the second window covers it.
Here's what I'd like to accomplish ultimately: I would like to always launch my program in Maximized stated (and disable resizing,
minimizing/maximizing is ok, just not double-clicking titlebar to resize) in the primary monitor (where Taskbar is being displayed). Then, when the button within the program is pressed, it launches the new window in the NEXT available monitor in Maximized stated.
have a question. The scenario is this Main monitor (17 inch) is used for POS system.Will have at least 2 more monitors (50 inch tvs used for digital menu)I want the main pos program to be able to set what is written there (easy on a form) but have different forms to ALWAYS go onto one of the tvs (they would be plugged in via VGA).
I have read some examples but I havent seen anything with different size monitors.How can i ensure that the main program runs on the 17 inch screen while the 2 forms of the menu will display on tv1 and tv2 and the same tv each time?
What im trying to do, is have my program run full screen on the primary screen, and diable all other screens. I have it 'full screen' and constantly on top of everything with this
Dim b As Boolean = _
SetWindowPos( _
Me.Handle, _
[code]....
It is in a timer, so its always on top. how do i turn off, or disable all other monitors, besides the primary screen. (How do i check if they have other monitors, and if they do, how many, and disable them all, with exception to the primary screen.)
Basically I'm trying to change the both if one display(monitor) is active and either turn off all active to displays to one display or change to extended display. Is there any api or similar to do this? My target OS is Windows 7. I'm making a program that can change one active display to having extended displays and vice versa. d. I use Visual Studio 2008 Professional or 2010 Ultimate Beta 2 with Visual Basic Settings.

View 1 RepliesBasically, I have a program that uses up one Monitor (With maximize/minimize/etc options), and I'm going to develop another window that by default, you'll have to swap to. But, if there are two or more monitors detected, throw the 2nd form on the 2nd monitor.
I have found a way to detect multiple monitors (Using the SystemInformation Class to return the monitor count), but it's placing the form on the other monitor that's the problem.
I am looking for a way to make my forms fit varying sizes of monitors. I am guessing that I need to determine the screen size.
