Just do it then. What exactly is your question? Opening a little form when you click on a button is very easy to do. Are you trying to figure out how to update the data flow metrics to the progressbar control?

What I want to do is programmically assign a Form to be displayed on a specific monitor connected to my computer. Say that I have more than one video card in my computer, what I wish to do is choose which card displays a Form.
I've been looking at the Screen[^] class, and it seems to have the functionality I need. Some code snippets I've found here and there show to take the Bounds property of a specific Screen and assign its value to the Bounds property of a Form. The Form will then be displayed in the specified screen.
However, the above, I think, assumes a multi-monitor situation in which the desktop is being displayed across two or more monitors. That's not my situation. I want to have more than one monitor that are independent of each other. The idea ultimately is to have a video being displayed on one form using Managed DirectX and another video being displayed on another form, both in full screen mode (and on seperate screens).
Unfortunately, I only have one monitor connected to my computer at this time, or I would experiment to see what happens. Before I go out and purchase a second video card, I thought I would post my query here to see if anyone can offer any insights into how I can accomplish what I described above. Thanks for your time.

Hi Leslie,
I dont have all the info, but here is some:
1.
in desktop-across-multiple-monitors, you get one large desktop, and the coordinates of
your Form decide where it will appear i.e. on which monitor(s), it could be split
over more than one. They dont have to have same dimension, nor same settings.
Task bar would be in primary monitor. IIRC maximize expands the form to a single monitor,
the one it occupied most or something like that.
2.
what is against multi-monitor desktop ? You can still have one form fill the first monitor,
another form fill the second monitor (etc etc)
3.
lots of laptops have a video out connector, often with a separate video controller
behind it. My Dell Inspiron can switch between off, same image as own monitor, or
separate monitor; so you could combine your monitor with someone's laptop and experiment.
Hope this helps

My goal is to give a multi-media presentation in which I have one or more screens in the background playing videos. When the videos are not playing, the screens should be blank, i.e. not showing the desktop. I don't want the audience being able to see the mouse moving around or elements of the desktop on the screen.
One obvious way to prevent this would be to switch off the display devices when there's no media playing, but I'd like to automate this as much as possible from the computer. Blanking out the screens may be possible using a mult-monitor set up, though.

That's a good suggestion, thanks.
At this point, I'm doing research for a client I've done work for in the past. If I can demonstrate that I can create the type of functionality I described above, I'll be able to move forward and do the job for them.

Hi Leslie,
some more ideas:
- you could create an app (or a service !) that shows several borderless windows, backcolor
or backimage of your choosibg, each completely filling one secondary monitor.
- Maybe, dont know, that app/service can hide the mouse when hovered,
even if not the active window.
- Not sure: you might be able to move the monitors apart from each other, i.e. have
gaps in the desktop, reducing the chance the mouse ever gets on a secondary monitor.
- if you first add all monitors to the desktop, give them their intended relative position,
then remove the desktop from them, then maybe, just maybe, they retain their coordinates
and you can still show windows at those positions. (I dont know how else you would ever
get anything to show on a monitor that is not part of the desktop !).
Extra info:
I have some code that uses EnumDisplaySettings and ChangeDisplaySettings; I use it
to programmatically modify my monitor's resolution (for reading small print !).
It would be easily modified to modify some other parameters for secondary monitors, so you
could effectively move them to the extreme corner of the 64K*64K virtual desktop;
and probably could blank them as well. I did not immediately see the "extend my desktop" bit
in the DEVMODE struct, maybe it is there, maybe not.
I feel confident your goal is technically within reach.

I've had some luck with this issue. Here a couple of code snippets:
protected override void OnLoad(EventArgs e)
{
foreach(Screen s in Screen.AllScreens)
{
if(s.Primary)
{
Debug.Assert(primaryScreen == null);
primaryScreen = s;
}
else
{
secondaryScreens.Add(s);
}
}
Debug.Assert(primaryScreen != null);
base.OnLoad(e);
}
This is in the main form. It goes through all of the "Screens" available on the desktop, storing the secondary screens in a collection.
if(video != null)
{
video.Dispose();
video = null;
}
video = new Video(openFileDialog1.FileName);
video.Owner = videoForm;
if(secondaryScreens.Count > 0)
{
videoForm.Bounds = secondaryScreens[0].Bounds;
video.Fullscreen = true;
}
videoForm.Show();
The above is from a method that handles opening a dialog box and letting the user choose which video to play. If there are any secondary monitors available, the first one is chosen and the video will display in a Form set up to display in the second monitor in full screen mode.
The code was written quickly and could use some improvement. I was just anxious to get something working as a proof of concept. Fortunately, it works. As far as blacking out the secondary monitor, that's easy enough by making the videoForm's background color black.
So far so good. The only problem with the above is that it requires that the secondary monitor be part of the virtual desktop. There may be situations in which I need to display a video on a device not part of the desktop. Oh well. A little bit of progress at a time...

I'll have to remember this if I ever jump over to dual monitor. Thanks for sharing

Hi,
I am using datagridview control on my usercontrol. And I want to set datagridview control's row as deselected using
DataGridView1SelectedRows[0].Selected = false;
I have a function call bind grid which returns dataset and in usercontrol;s load event I bind it with datagridview. and next line is
DataGridView1SelectedRows[0].Selected = false;
but at this point runtime gives me an error like below...
first error message is " Index was out of range. Must be non-negative and less than the size of the collection."
Actual Error message is "this code has called into another method, when that function is finished, this is the next statement to be executed"
if anybody has any idea then please let me know...
Thanks Code project...

I would like to develop a feature from Linux Xserver that makes it possible to resize the currently active window by holding down a key sequence and drag the mouse. My problem is that I need to use the unmanaged Windows API to do that, and I can't get it to work.
I've tried to use a global mouse hook and get the window handles from under the mouse, but I could only get X,Y coordinates, and not a usable window handle.
Do you have any ideas on how to do this?
Edit: I used this to get the X,Y coordinates, but it's only a local hook (but I get a usable window handle, but since it's local, I only get the handle on the form, and not any other window)

Hello There,
Can anyone let me know how can we add a row to a datagrid/datagridview control on the click of a button. The problem we face is that we can add the combobox once, but on further clicks the comboboxes are getting added in a separate column of the grid rather than the same column.
I hope I am clear with my doubt. A link to a sample app can also help me immensely
Thanks and regards,
ATUL

Hi
Iam developing a desktop application in .net1.1.How to give shortcut keys to the buttons in the toolbar control?pls giv the solution for it.
|
|
|
|
|
Hi,
the easiest way is to have a MainMenu, with MenuItems each covering the same functionality
as the toolbar buttons; then assign a ShortCut property value to those MenuItems, and
you get it for free.
If you dont like this, you must handle the keyboard events, test for your letter(s)
and check the Control.ModifierKeys value at the same time.

I am currently breaking throuh the ice of Windows Forms, this development environment is a bit different from what I'm used to. Basic functions and structures does not work like I want them to which creates huge ammounts of frustration since I get stuck at nonsense.
I would need something like a "Beginners Basic Tutorial that leads you by the hand with small babysteps towards great achievements". If someone know where I can find this, please point me towards it.
For the moment I'm creating a simple zoom-function for an image and I want to use an array for the different zoom-sizes. I can't figure out how to declare the array and hardcode some doubles into it. This is a quite typical example of what I get stuck at, please enlighten me on how to declare them arrays.
::peace

Dim ZoomLevels() As Double
Seriously, before you frustrate yourself out of a job, pick up a book or two on Beginners VB.NET.

That's not an array or is it?
