DllStructGetSize byte size

3 posts in this topic

#1 ·  Posted (edited)

Hi,

I don't understand how the size of the structure works.

 

I know that an int has a size of 4 bytes, if I get the size of the struct then I have 4 bytes;

a byte has as size of 1 byte, if I get the size of the struct then I have 1 byte.

 

Until here everything seems fine, unless I make a structure with the two elements, the size is 8 bytes; 4+1=5 and not 8.

 

Here is the example :

#include <Constants.au3>
 
Local Const $tagSTRUCT1 = "struct;int var1;endstruct"
Local $tSTRUCT1 = DllStructCreate($tagSTRUCT1)
 
MsgBox($MB_SYSTEMMODAL, "", "Struct1 Size: " & DllStructGetSize($tSTRUCT1))
 
 
Local Const $tagSTRUCT2 = "struct;byte var2;endstruct"
Local $tSTRUCT2 = DllStructCreate($tagSTRUCT2)
 
MsgBox($MB_SYSTEMMODAL, "", "Struct2 Size: " & DllStructGetSize($tSTRUCT2))
 
 
Local Const $tagSTRUCT3 = "struct;int var1;byte var2;endstruct"
Local $tSTRUCT3 = DllStructCreate($tagSTRUCT3)
 
MsgBox($MB_SYSTEMMODAL, "", "Struct3 Size: " & DllStructGetSize($tSTRUCT3))
Thanks for anyhelp :)

Br, FireFox.

Firefox, we need to use align here. Read help file for DllStructCreate() function

FROM help file:

DllStructCreate("short;int") ; structure is 8 bytes, the "int" is at offset 4
DllStructCreate("align 2;short;int") ; structure is 6 bytes, the "int" is at offset 2

I already read the helpfile ofc, I just didn't understand how it worked. Had to have a little break to get it.

Thank you.

      Hi all,

      I am having a little trouble with ‘GUICtrlSetResizing’ an hoping someone could push me in the direction of best practice.

      I have a basic GUI created to a set size with the enabled abilities to resize it:

      GUICreate("Test", 500, 450, -1, -1, BitOR($WS_SIZEBOX, $WS_MAXIMIZEBOX, $WS_MINIMIZEBOX))

      Inside this I have an image and label:

      GUICtrlCreateLabel($Image1StampInfo, 10, 395, 480, 20, $SS_CENTER) GUICtrlCreatePic($TheImage, 25, 25, 450, 350)

      Using:

      Case ($GUI_EVENT_MAXIMIZE or $GUI_EVENT_RESTORE or $GUI_EVENT_RESIZED)

      I activate:

       
      GUICtrlSetResizing($TheImageBox, $GUI_DOCKAUTO) GUICtrlSetResizing($Image1Stamp, $GUI_DOCKAUTO)

      This works fine with the image but not with the label – the label after a bit of resizing seems to get stuck in different places in the GUI as if the $GUI_DOCKAUTO has not worked properly.

      So 2 questions if I may. 

      1)    Have I used $GUI_DOCKAUTO incorrectly for use with lables?

      2)    I am happy to manually set new sizes dynamically but how? I can get the size of the window with ‘WinGetPos()’ but how do I set new size parameters for the ‘label’ and ‘image’?

      Thank you in advance.
