nsDialogs: disable a NSD_CreateBrowseButton
Hi,

I have the following code:

    ${NSD_CreateLabel} 0u 30u 89u 12u "Choose path:"
    ${NSD_CreateDirRequest} 90u 28u 180u 12u ""
    Pop $INST_DIR
    ${NSD_CreateBrowseButton} 275u 26u 25u 16u ...
    Pop $BROWSE_BUTTON
    GetFunctionAddress $0 BrowseButtonAction
    nsDialogs::OnClick /NOUNLOAD $BROWSE_BUTTON $0
    [...]
    ${If} (some test)
        StrCpy $R1 "${DEFAULT_INSTDIR}"
    ${Else}
        ${NSD_ENABLE} $INST_DIR 0
        ${NSD_ENABLE} $BROWSE_BUTTON 0
        StrCpy $R1 ""
    ${EndIf}
    SendMessage $INST_DIR ${WM_SETTEXT} 0 STR:$R1  

I want to disable the browse button (no action when pressed). The NSD_ENABLE macro -which comes from this very helpful example- doesn't work on my BrowseButton $BROWSE_BUTTON.... but work on the DirRequest $INST_DIR... any idea ?

Here the macro def:

!macro _NSD_ENABLE NAME TOGGLE
       SendMessage ${NAME} ${WM_ENABLE} ${TOGGLE} 0 $R0
       Push $R0
!macroend
!define NSD_ENABLE `!insertmacro _NSD_ENABLE`

I know that I can just move the OnClick function assignment into the If clause to fix this issue, but wanna understand why it doesn't work.

The NSD_Enable macro, as I said in that thread, is invalid. It shouldn't send WM_ENABLE, but should use the built-in EnableWindow.

Oups... sorry... I forgot that comment you made.

Thanks ;)
