[x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
Re: [x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
I can't say. All I know is that I experience the same issue as tempuser. Sometimes the script works, sometimes it doesn't. Is it possible that both our issues stem from "OpenProcess" not working? Maybe, but it seems from the warning that iProcessID is blank, which results in OpenProcess not working. Having placed a Msgbox in the code, sometimes hwWindow is blank, which would make "WinGet, iProcessID, PID" blank and so on down the line. My humble opinion is that one of the "ControlGet, hwWindow" commands is failing, which leads the other functions to fail.

Restores or gets the position and text of all icons on the desktop.
Parameters:
Data:
Specify the returned object to restore the position of the icons.
Omit this parameter to retrieve the information.
Return value:
If it is to be restored, it returns the number of icons moved; Otherwise it returns an object.
The object contains the following format: {IconText: {X,Y}}.
If the function fails, the return value is zero. To get extended error information, check ErrorLevel.

Re: [x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
DeskIcons() is nice as far as it goes, but I am at a loss as to how to take the next step, setting arbitrary icon positions.
If I dump out coords I get
That 64816202 number (for Handbrake) must be a coordinate or related to one.
And by adding the following to DeskIcons()
I can see that Handbrake (via iCoord) is at X: 1098 & Y: 989, which are Relative positions. Checking with WinSpy that agrees.
But I am not sure how I arbitrarily set a coordinate for the icon.
If I want to move the Handbrake icon from its original position to ... say .. X: 2000 & Y: 1500, how would I go about that?
What is that packing and bit shifting that occurs with the ret variable?
Thanks

Do you want to set the position of a specific icon?; We need another function for this (Not necessarily, but it would be fine). *I have added SetDeskIconPos to my previous Script.ahbi wrote:If I want to move the Handbrake icon from its original position to ... say .. X: 2000 & Y: 1500, how would I go about that?
See the lParam parameter of the LVM_SETITEMPOSITION message. You need to package the coordinates (x;y) in a 32-bit integer. See MAKELONG macro | Packaging values in DWORD.ahbi wrote:What is that packing and bit shifting that occurs with the ret variable?

Re: [x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
Hi Folks,
Can this script be adapted to get the dimensions of the icons as well, perhaps through LVM_GETSUBITEMRECT? Ultimately, I am trying to find a way to get the name of the icon under the mouse.
Thank you,

Re: [x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
Does anyone know of a simple way to keep the icon location data persistent between reboots. Every time my desktop gets redirected and I log in the icons are changed, so it would be nice to be able to save the config between boots/exiting the program.
Re: [x64 & x32 fix] DeskIcons - Get/Set Desktop Icon Positions
Yeah I've had that issue before, I had made a script to save the icon positions to a file, and I would simply load it and restore the positions from the file with this function.

What does not work:
If i'm logged in as normal domainuser and run the script with elevated rights as domainadmin. In that case it looks like the OpenProcess function denies access.

I played a little with dwDesiredAccess. The minimum we need is:
It also works with the max of 0x1F0FFF.
But it doesn't help in my case with elevated rights.
Now i got it:
It works, if you join the normal user to the administrators group.
So i have to make a standalone exe-file, which runs with normal rights.
Code: Select all
hProcess := DllCall("OpenProcess" , "UInt", 0x18 ; VirtualMemoryOperation|VirtualMemoryRead
, "Int", FALSE ; inherit = false
, "ptr", iProcessID)
