forse non ho capito bene.....è giusto così?
Nome dell'applicazione SetWindowTheme.exe

Si parte con il codice

SetWindowTheme.rc

//Microsoft Visual C++ generated resource script.
CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST "SetWindowTheme.exe.manifest"

SetWindowTheme.exe.manifest

//Questo sorgente è stato aggiunto all'albero del progetto

Non ho caricato in memoria la .dll Comctl32.dll, ma ho usato un #pragma comment(lib,"Comctl32.lib")....

risultato sempre quello di prima e niente barra verde

[kirakira93]

Ecco ho fatto una modifica al codice seguendo le istruzioni di MSDN....ecco il codice....e il risultato è sempre lo stesso -.-"

Le modifiche sono state applicate dentro WM_CREATE e WM_DESTROY

mItaly...avevi detto che quando finivi gli esami ci davi un occhiata più approfondita qui....
prefavore puoi farla......


Comunque penso che il problema sia settare un opzione in visual studio, perchè con dev-c++ funziona! basta mettere il manifest nella cartella dove ci sono gli altri file

[MItaly]

Eeeh finiti, altri due a settembre.

Comunque, secondo me dipende dal fatto che i manifesti in VS2008 sono gestiti dallo strumento manifesti, io darei un'occhiata in quella direzione (nella tab apposita nelle proprietà del progetto).

[kirakira93]

è proprio questo il problema in internet ho trovato pochissimo...dopo provo a vedere se c'è qualche opzione che estisce i .manifest.

Comunque ho visual studio 2010.....





EDIT


CE L'HO FATTA: aggiungendo il manifest nelle risorse del progetto!
