Can anyone tell me why im gettting a fatal error at when i make my call to RegSetValueEx? and when i create a key do i have to close it befor writeing to it? or can i just write to it right away?
.data
subkey db "Software\Tray_Protector\Pass\",0
.data?
keyholder dd ?
dispo dd ?
tpass db 20 dup(?)
rpass db 21 dup(?)
rdpass dd ?
.code
invoke RegCreateKeyEx,HKEY_LOCAL_MACHINE,addr subkey,0,NULL,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,NULL,addr keyholder,addr dispo
invoke RegCloseKey,HKEY_LOCAL_MACHINE
invoke RegOpenKeyEx,HKEY_LOCAL_MACHINE,NULL,0,KEY_ALL_ACCESS,addr dispo
invoke GetDlgItemText,winhand,IDC_NEWPASS1,tpass,20
invoke RegSetValueEx,HKEY_LOCAL_MACHINE,addr subkey,0,REG_SZ, addr tpass,sizeof tpass
invoke RegQueryValueEx,HKEY_LOCAL_MACHINE,addr subkey,0,addr value,addr rpass, addr rdpass
invoke SetDlgItemText,winhand,IDC_NEWPASS2,rpass
I don't see trouble with RegSetValueEx but I see this one:
invoke GetDlgItemText,winhand,IDC_NEWPASS1,tpass,20
The third parameter to GetDlgItemText must be the pointer to the buffer. It should be like this:
invoke GetDlgItemText,winhand,IDC_NEWPASS1,addr tpass,20
Also in RegCreateKeyEx, you SHOULD NOT use KEY_ALL_ACCESS. It is ok if you want your prog to be able to work only under win9x. That RegCreateKeyEx would fail
miserably under win2k with error "Access denied" because Win32 api states that you can't create a subkey under HKEY_LOCAL_MACHINE and JEY_ALL_ACCESS does include the the access right for subkey creation.
Also this line:
invoke SetDlgItemText,winhand,IDC_NEWPASS2,rpass
should be:
invoke SetDlgItemText,winhand,IDC_NEWPASS2,addr rpass
