I want prevent the parent dialog, not move.
when dialog process data (17s) i can move the parent dialog to anywhere.
You can remove the title bar of the window by removing the title text and setting the ControlBox, MaxmimizeBox and MinimizeBox properties to false.
I would however think twice before doing this; there are very few things that annoy me as much as a user, as windows that position themselves topmost at the center of the screen, with no option to move them away to keep on working on something else.

I have a wide "dock" area at the bottom of the screen. I have placed a UIFocusGuide across the top of it. Depending on which element in the dock has focus, the system may or may not have a focus solution if the user swipes up.
How can I tell my focus guide to use the system-calculated new focus item if there is one, but if not, it should use the one configured in my setPreferredFocusEnvironments:
Alternatively, is there a way to determine where a "swipe up" will take the focus without actually doing it? As the focused element in the dock changes, I could check this and if it has no destination provided by the system, I can add one.
My dock is a view within a main view controller but preferredFocusEnvironments is never called when the user tries to move to a non-existent view from an element in the dock.
I created an interface it has several forms you can switch between using a panel as the parent form. My problem is that when i switch between my forms on the second time i open a form if that form has autoscroll on a panel it will not allow you to scroll and the window is stuck on the view you previously had.
In this image i open the form internet. after doing so i will click on instruction( any form switch triggers this)
now i open the same form again and the scroll bar is gone and it locks in on the last position the form was in.
the very curious thing in this is that this only happens on the internet form word also has a scroll bar however even though the properties and settings for both are identical only one does not work.
What could be causing this and how do i go about troubleshooting errors like this.
The forms are removed from the panel and re-added, they are not closed.
Assumption 0:
The forms are removed from the panel and re-added, they are not
closed.
Store the state of panel autoscroll and set it after you have re-added it. Note that if you add controls to the panel first and panel is not docked, then scroll will not appear because panel dimensions can be huge. You should set following property as well:
vScrollBar1.Vericalscroll.Value = 0
Assumption 1:
I assume what is actually going on is that you do not add controls to that panel, but to the form behind it or something similar. In that case - program is correct, you just asked it to do a wrong thing.
Assumption 2:
Assuming is panel is anchored top, left, bottom, right. There is currently a limitation in Windows Forms that prevents all classes derived from ScrollableControl from acting properly when both RightToLeft is enabled and AutoScroll is set to True.
Manual : link
Assumption 3:
You add the controls back, by recreating them, but forget to add handlers or create them in order where scrollbar is out of view. Instead of absolute positions you could use dockstyle:
Dim vScrollBar1 As VScrollBar = New VScrollBar
vScrollBar1.Dock = DockStyle.Right
Controls.Add(vScrollBar1)
If set popup's IsLightDismissEnabled = true ，when popup show ,popup will get focus , other control will lost focus.
My question :How can I keep the focus;when the popup show ?
That's counter-intuitive, in my opinion. IsLightDismissEnabled effectively means "show this popup, but once it loses focus hide it". If you aren't giving your popup focus, or setting focus to another control programmatically, it will either show until you carry on interacting with your form, or not show at all (not sure which, I haven't checked it)
Is there any property of pop up , wherein we can dim the window app.
As in metro app there is no Child Window control available , so using
popup in place of it but the problem in popup is when it is open the
user can still interact with other control on window app.
So is there an workaround to make the window app dim when pop is open.
I'm not sure to understand what your trying to do. You can put a Border as first child of the popup which exposes the Background property. So if you specify a not null Background (Transparent for instance) the popup will catch every interactions.
It sounds like you want the MessageDialog class. The popup is meant to be non-modal, letting the user close it by just clicking away from it. The MessageDialog is a regular modal popup that does not let the user interact with the rest of the app when it is displayed.
If you really insist on using the popup control, here is a simple workaround:
Make the popup use all the screen (using a grid or border), then set that background to Black with opacity 0.1 (or any other color you see fit, this is to give a "dim" effect), then inside this popup, place another container with the size and margins that you want to act as your "real" popup.
Because the popup takes the whole screen it will prevent the user from clicking anywhere in the screen.
I have a small application in which I need to show alerts if a particular condition is met. I have an mdi form and several child forms. Now the best way to show an alert is to show a tooltip on the right side corner of my mdi form. Though this works, but the problem is I want user to close the tooltip once he has read.
Now the tooltip that vb.net provide does not support click events. If I give a long time duration the tooltip would be open all the time and if I give a short duration then it will close quickly.
What can I do ?
Help will be appreciated.
Thanks,
GR
You might consider a statusbar at the bottom of the window instead of a tooltip (like at the bottom of Word). You can intercept clicks on those, split the bar into several sections as necessary, etc.
Alternately, I'd probably code up a little pop up form with no border, min/max.close buttons etc, like a toast message, and show it as necessary, Stick an RTF control on it and you're "tooltips" can be very richly formatted, add a timer and the window can disappear after a short timeout, or intecept the click and close it manually.
