Detecting Multiple Monitors & Centering Different Forms?
Oct 25, 2009
Basically, 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.

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?

I have created an application that uses two forms one is displayed on a touchscreen and is a basic input form, the other is displayed on a large display monitor and is basically an information form, both displays are connected to the same pc. The program works great I have just one annoyance is if the program is restarted it displays both forms on the touchscreen and I have to drag the information form onto the big display. Is there a way to specify on load that each form gets displayed maximized on a certain screen so I don't have to drag one form onto the correct screen?

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.

I have build custome windows in my application with cust contorl box on the top right corner. Minimimize, maximaize and close button are made by me.
I want to make another button beside that one which will control displaing of windows in multiple monitors environment. So, cllick on that button will list monitors and I send that window to second monitor.

I am creating a Jeopardy type game and I want to be able to have the same form show on multiple monitors at times and at other times show a form only on one monitor. I have no problem getting a form to show up on the second monitor, but when I try to show the same form on multiple monitors I run into problems.[code]...

I'm trying to calculate the size of multiple monitors together, like the display size. This is an example of what I am talking the Size of the Virtual Screen"). I tried the code, with no luck. The WinAPI didn't seem to do anything, but take space in my code edit

I have an application that produces a form whose objects are scaled to the width and height of the primary monitor whose parameters are obtained from:
Dim ScreenWidth As Integer = Screen.PrimaryScreen.Bounds.Width
Dim ScreenHeight As Integer = Screen.PrimaryScreen.Bounds.Height
So far, the program works fine. A possible problem arises when multiple monitors are being used that do not share the same resolution. For example, if the 2nd monitor has a low resolution, then the form is cut-off.
I'd like to:
1.) determine that more than half the form has been moved to another monitor
2.) determine the resolution on the second monitor.
I suspect that the following command will give me all the dimensions that I need:
Dim ScreenWidthUsed As Array = Screen.AllScreens
In which case I just need to determine the screen that is hosting more than 1/2 the form.

New to these forums but have been a lurker for a while. I searched through some "multiple monitors" threads but didn't find anything that fit my current issue, so I figured I'd pose it in a new thread. We have users with 4 monitor setups that are very particular about their screen settings. When we have to replace a PC for whatever reason, it is always a hassle getting their screen configurations the way they were prior to the switch. Is it possible to create a small VB app that will scan their current configuration, save a "settings" file, and re-apply the settings on the new PC? What I mean by configuration is screen resolution, setting the primary monitor, etc. Theoretically this sounds like it can be done, but I wanted some opinions on it.

Maximized Window Size - For Multiple Users (Computers/Monitors)
View 1 Replies
Jul 12, 2009
Say you have a form that is designed to be maximized on startup. Now, on the programmer's computer (mine), it looks good. But going from user to user, the dimensions of monitors, as well as the resolution each user has on their computer/monitor will vary.Here is the question: If you want to have an application designed to be in a maximized window, how do you ensure that it looks the same on each and every computer/monitor that will be using it. Controls, and everything else that would normally be on the form.

My program runs and loads an icon into the system tray, the only way to them open the main MDI is to right click on the icon in the system tray and choose an option from the pop up menu shown. This all works nicely when there is only 1 monitor. As soon as you run this program on a computer with 2 monitors the icon does not show in the system tray.What do I need to do to make it work in this situation. I use shell_notifyIcon API

Now this program will only be used on systems that I produce, and send out. I need to make sure that for any monitor that these people use it will always be at the standard resolution of 1440 x 900..
I have tried setting up profiles with catalyst control panel, but if you plug in a different monitor to the one that was plugged in when you made the profile it wont recognise the screen and the system wont run properly.
So I wanna see if I can change the resolutions of the screen that will be plugged in the monitor slot and also if possible make sure the other extended screen should there resolution of 1024 x 768..how much control can you get over the monitors that are plugged in?

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

I typically prompt the user to save changes in the FormClosing event in MDI children. The application updater uses a Process.CloseMainWindow call to close the application if it's running before the patch update is applied.
I need to detect when the updater is closing the application and NOT prompt the user to save changes but save them automatically. I've tried using the System.Windows.Forms.CloseReason but this method isn't working for me. I capture the CloseReason in the MDI Parent FormClosing event but it's called AFTER the MDI children are told to close. I tried capturing the CloseReason (e.CloseReason) in the MDI child's FormClosing event but it registers as MDI Parent closing and a normal application exit is also going to raise this same e.CloseReason so I can't auto-save here either.
So my question is: How can I detect this Process.CloseMainWindow being used to close my application so that I can bypass all save prompts and save automatically? What is the first event called in this method of closing so that I can signal all MDI children that are open in their FormClosing event to just save?

I would like MyProcess() to fire when I click on any of several checkboxes. I could do it like this. [code]I have alot of checkboxes, and anyway, this method isn't very scalable.Is there any other way for a form (or panel maybe) to detect mouse events on child controls kind of like the way the KeyPreview property of a form allows it to detect key events of it's child controls?

I'm new to VB 2010 but have be using VB6 for many years.I'm currently stuck trying to store the state of open MDI childs at the moment the MDI parent is closed. Clicking the parent upper right close button appears to close all open MDI childs before running the parent 'Closing' or 'Disposed' events.I am therefore unable to detect which MDI childs are open and cannot restore them next time the application is run.Is there any other event for the MDI parent I can detect the start of the closing process before the children are closed?

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2

i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.

I was writing an application that draws a bunch of random lines on a form with the mouse move event. I set the windows start position property of the form to center screen, but no matter what I did the form would appear in the windows default position. After around 30 minutes of cutting code and trying to paste it into new projects, it still wouldn't center the form. I finally gave up trying to center the form by setting the form property, so I changed it to manual and wrote code that centered the form horizontally, and around 50 pixels from the top edge and the code worked. Has any one else had this experience with VS 2005 proffesional?It was really bugging me for some reason.
