UninstallCaption problem

[lovespy108]

Var myCaption
(1)UninstallCaption "Application unintaller"
(2)UninstallCaption "$myCaption"

Function un.onInit
StrCpy $myCaption "Application unintaller"
MessageBox MB_ICONQUESTION|MB_YESNO "some words" IDYES +2
Abort
....
FunctionEnd

If I use way(1),the caption of MessageBox is "Application unintaller".

but if I use way(2),MessageBox has no caption.

What's the reason?

Thanks very much!

When you change the value of $myCaption in the function it does not change the value in the caption as the function is not ended yet. if you check in a section aftes the initalisation of the uninstaller you can see that the caption has changed

[fabian.rap.more]

Function un.onInit
StrCpy $myCaption "Application unintaller"
MessageBox MB_ICONQUESTION|MB_YESNO "some words" IDYES +2
Abort
FunctionEnd

Caption "$myCaption" ;if on top then the uninstaller will crash

Section
MessageBox MB_ICONQUESTION|MB_YESNO "some words" IDYES +2
SectionEnd

Hi there!


The caption is initialised at runtime. You have to set the caption by other means.

Have a look at this wiki article:
