Of all the events (seventeen), I've only managed to "catch" in the handleEvent these (ten):

Code: Select all  Expand view

WM_NCPOINTERDOWN  
WM_NCPOINTERUP    
WM_NCPOINTERUPDATE
WM_PARENTNOTIFY  
WM_POINTERACTIVATE
WM_POINTERDOWN  
WM_POINTERUP  
WM_POINTERENTER  
WM_POINTERLEAVE  
WM_POINTERUPDATE  
 

Does anyone have any idea why the rest are not detected?

Saludos

About ten events that are only treated. It must not be coincidence that http://social.msdn.microsoft.com/Forums ... e169bac0a5

Antonio,

Many thanks for sharing this info. I wasn't aware of these WM_POINTER... new messages.

What I don't see is whats the difference with standard mouse events.

How did you notice that you needed them ? What was not working ?

Are you using your FWH apps on a Windows tablet ?

[Antonio Mart.]

Antonio,

Yes, I use a Asus Vivo Tab Tablet with Windows 8 desktop.

I need these WM messages to scrolling in dialogs with the finger "pointer". The pointer finger WM messages are *NOT* similar to mouse messages WM: are different. Looks like this was already the case in Windows 7.

WM_POINTER messages have appeared with Windows 8. The WM touch in Windows 7 messages are legacy.

Thanks for your interest.

[Antonio Linares]

Antonio,

I don't have a Windows 8 tablet yet

Where did you buy it ? How much is it ?

Hi Antonio,

Hi,

Wow!
Clicking get control, it will scroll automatically if you are *NOT* running a drag touch.

Antonio,

I don't have a Windows 8 tablet yet

You can get it online.. You have to good balance in your account for getting a best tablet.

Hello Antonio Mart.,
this is a powershell script to change 'ScrollWidth' and 'ScrollHeight' which is working for me.
You read the different ntuser.dat files into a temp User in registry set the values and save back.

Best regards,
Otto

clear host

$null = New-PSDrive -Name HKU   -PSProvider Registry -Root Registry::HKEY_USERS
Get-PSDrive -PSProvider Registry

$array = @("UserName1", "UserName2", "UserName3", "UserName4" )

foreach ($element in $array) {

$element

$cQuelle = ' c:\users' + $element + '\ntuser.dat'
$pfad = 'HKU:\Testuser\Control Panel\Desktop\WindowMetrics'

Hello Otto,

Thanks for your input. I'll try.
For me the problems were reduced with the scrollbar.
I wanted to remove the scrollbar of the dialogues. Because you can not delete them then I thought of greater width.

But then I did something: hide! How to hide, if Windows does not allow it?

My forms (on tablet) consist of a title and a folder, without borders, below. Each folder has a scrollable dialog with controls that interact with the Tablet Input Panel (virtual keyboard). What I do is size the size of the dialogue out of the folder and so the scrollbars are not shown. Of course, the user can navigate within the dialogue touching style. Is like a Windows 8 style, forms and navigation;-)

Regards

[Antonio Mart.]

Hi,

Code shows how to hide a dialog when it loses focus. The function must be placed in the Init event.
Below pictures of a form with scrolling style touch with touch movement and without scroll bars and with automatic deployment TabTip.
