Description

Bug: _GUICtrlListView_SetColumnWidth et al. lack proper typecasting in GUICtrlSendMsg

Description: the $iWidth parameter in _GUICtrlListView_SetColumnWidth($hWnd, $iCol, $iWidth) causes the UDF to run havock when $iWidth is a numeric string. E.g.: _GUICtrlListView_SetColumnWidth($ListView, 0, 100) works fine but _GUICtrlListView_SetColumnWidth($ListView, 0, "100") doesn't.

This bug was found calling the UDF with a numeric value read from file as a string. The UDF source reveals that GUICtrlSendMsg is called without typecasting to the correct lParam type. Appearently GUICtrlSendMsg doesn't do it either, which is an even more severe bug.

Demo: slightly extended demo from _GUICtrlListView_SetColumnWidth demo in help file. See below.

#670 No Bug Listviews with checkboxes doesn't work "properly"....in my opinion anonymous
Description

I'm too lazy right now to take apart my code to show an example, so hopefully what I say is understandable. I set up a listview in conjunction with a WM_Notify function. When the CELL of the checkbox is clicked, it registers but the box isn't checked, which throws off my function. I believe that if the surrounding cell is clicked the checkbox should be checked as well. If this is not a "bug" I think this should be how it functions...unless there is a specific reason why it isn't like that.

Note: As a workaround I tried to put in the function to check if the checkbox is checked after there is a register on that item and then check it if it isn't checked...so if someone clicks the surrounding cell...but that doesn't work at all.
