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 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'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.
[code]...
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 7 RepliesI want to know how can I make a program what will work in any type of resolution & monitor. For example if I make an application fullscreen it will work. But problem is that text boxes or another things will not work properly. For example if I make a program & make it fullscreen for 1440 * 900 resolution it will work fine when it will get 1440 * 900 resolution. But when it will get different resolution like 1280 * 1024 or something like that it will make my application fullscreen but buttons or another things will not be present there in same place. So what should I do to get rid of this problem? All I want to make a program what will adjust itself everywhere(though you change resolution or monitor like 17 inch or 29 inch whatever it will work & buttons & another thinks will be there in same place).
View 1 RepliesCan I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..

View 1 RepliesI 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).
The command works but im getting an incorect time It returns 15/9/2009 12:00:00 the date is fine (was ok when this thread was written)but the time is always the same 12:00:00 Is something wrong with the server or am i entering not the right command?

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.

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.

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).

2 Then after searching or reading the record from table and selected fields save the unmatch records in a new table
I have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click
Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top))
Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?
