Limiting moves of a borderless window ...

5 posts in this topic

Hi,

i'm trying to limit the moves of a borderless GUI. i'm on an example taken from Moving and Resizing PopUp GUIs.

I'm using the _SendMessage function so far :

While 1     
    Switch GUIGetMsg()         
    Case $GUI_EVENT_PRIMARYDOWN             
    _SendMessage($hGUI, $WM_SYSCOMMAND, $SC_DRAGMOVE, 0)   
    EndSwitch
Wend

I would like to add some constrain on the X,Y coords of the window (for ex. forbid X exceeding 1000) ...

How could i achieve that ? It Seems to me that i have to follow two events at the same time (EVENT_PRIMARYDOWN + EVENT_MOUSEMOVE) but i'm not sure to be on the right track ...

Could anybody help me ?

Thanks ...

WinGetPos  returns an arry 

     $aArray[0] = X position
    $aArray[1] = Y position
    $aArray[2] = Width
    $aArray[3] = Height

if x y exceeds your desired position then reset window to what you want.

Thanks for spending some time on my question Reb but your code is not doing what i would like :

Your code allow the user to go out the "restricted area" and then check whether the moved window respect the x,y limitations.

What i would like is a way to force the x,y limitations during the move ...

      Hello all ~
      I am running an autoit script on Windows 10 inside VMware Workstation 12 Pro version 12.5.2.  Technically I am remoting into ESXi which has a Domain Controller (DC), WebServer, FilServer, Windows 10, etc.  Using the GUI (i.e. running explorer.exe) I am able to open several different folders successfully.  The desktop, documents, USB external all open without issue.  The network share opening gives me issues.  Whenever I attempt to open \\filserver\users\user\sharedfolder I get the documents folder instead.  I understand that the documents folder is the default for explorer.  I have also attempted to use the letter drive mapped to the network share (Z:) and receive the same result.  When I run this script on Windows 10 alone without  the VM or the ESXi I am able to open the network share without problems.  I have tried to use the net use command to designate a letter M: to the network share folder prior to running the script.  This did not work for me.  
      One additional avenue I think might work is to use the systreeview321 and _GUICtrlTreeView_FindItem to step through the tree looking for the network share.  Once found,  double click on it and see if that opens the shared network folder.  I can click inside the VM with my mouse on the network share and it opens just fine.  Not sure if running up against GUI issues, or permission issues, or what?
      Thanks in advance,
      Davida Crozier

      This script is a subset of a much larger program, but it illustrates what I am dealing with.

      Hi everyone,
      GUICtrlSetState Function example ,i found $GUI_DROPACCEPTED isn't working in windows10 x64(windows_10_enterprise_2016_ltsb_x64).
      if the example put to windows10 x86 or windows xp, the $GUI_DROPACCEPTED is effective,
      the AutoIt Edition is v3.3.14.2.
      any ideas? thanks you.

      Hey Guys,
       
      So, the functions work, where primarygui() accurately determines the evaluation of the status of the checkboxes - the msgbox picks this up.
       
      However, later on, when we re-enter a 'for $i = 0 to ubound($checkbox)' loop, then in the 'batchinitial' function it doesn't picked up that the status&$i = 1, so it jumps out, then within the While 1 loop, it exits the loop in the first row, again because the status& $i= 0
      The "assign" line within the primarygui funtion, is this only a local assignment? if so, how can I make it cross function?
       
      Thank in adv for your help

      Hello everyone !
      While writing a sample of code to test ping to my internet box, I got stuck..
      While the code is Pinging with let say.. 5000ms of timeout, I need to update a progress bar from 0 to 5000 ms at the same time but I don't know how could I do this..
      Is there a way or something that could get around the pause of the ping like in InetGet -> InetGetInfo?

      Here are two functions to provide pixel-accurate height and width dimensions for a given string.
      The more commonly-used _GDIPlus_GraphicsMeasureString built-in UDF is problematic because it returns the width padded by roughly one en-space (for reasons related to the various ways Windows produces anti-aliased fonts).
      These are AutoIt translations of Pierre Arnaud's C# functions, described in his CodeProject article "Bypass Graphics.MeasureString limitations"
      The first is an all-purpose version that takes a window handle, string, font family, font size (in points), style, and (optionally) width of the layout column (in pixels) as parameters.
      The second, more efficient version is intended for applications where GDI+ fonts are already in use, and takes handles to the existing graphics context, string, font, layout and format as parameters.
      Both functions return a two-row array with the exact width [0] and height [1] of the string (in pixels).
      EDIT: (Note that some of the same anti-aliasing measurement issues still apply. I did my best to work around them, but the output of the function may still be off by a pixel or two. Buyer beware.)
