Custom Query (3927 matches)

I couldn't find this any where in the documentation, but DllStructCreate and the related functions do have a limit to what characters can be used for an element name. So far, we found the following letters are allowed:

A-Z,a-z,0-9

(There are more, but for brevity sake, I'll only list these.)

I had 2 questions about this limit. Why does the element names not allow underscores while C structs allow them for names, and can we add these limits to the DllStructCreate (and possibly others) help entries? A few DllStructs I have been trying to use from MSDN contain underscores, and it took some experimenting to discover why my code kept failing with improper Struct variables, until I finally took out the underscores from the names on a hunch.

The forum post where I asked about this is here:

To reproduce the bug, just open some Explorer window (folder), and run this script:

ControlCommand("[CLASS:CabinetWClass]", "", "SysListView321", "GetSelected")
MsgBox(64, 'Title', 'Crash!') ;Not shown

I know that "GetSelected" should be used on Edit control, but i came across this issue trying to get the text dinamically (in loop - for current control, using ControlGetFocus). And i think in any case script should not crash.

Documentation says that the size of 'ptr' with DllStructCreate() is 4 bytes and unlike with, for example, 'int_ptr' there is no mention of differences when x64 AutoIt is used. I would assume it's the same thing with other alike types.

$tStructure = DllStructCreate("ptr")
$iSize = DllStructGetSize($tStructure)

ConsoleWrite("Size of ptr = " & $iSize & " bytes" & @CRLF)
MsgBox(64, "ptr", "Size = " & $iSize)
