Why do you think you need to use this function? What are you going to be doing with it once you learn how to use it?


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Thanks BrewManNH there are many function that can i call using Dllcall(like Connecting a vpn without using operating system function)but every time dllstructure  becomes me crazy..................

typedef struct {
  DWORD dwSize;
  DWORD dwMask;
  TCHAR szUserName[UNLEN + 1];
  TCHAR szPassword[PWLEN + 1];
  TCHAR szDomain[DNLEN + 1];
} RASCREDENTIALS, *LPRASCREDENTIALS;

How can i create this structure in autoit? what can i put at the place of dwSize and dwMask?
and what does mean of [uNLEN+1]&[PWAN+1]?
Microsoft structure Link...  and dll function link in witch this structure used

dwSize is set to the value of DllStructGetSize() of created struct. dwMask is the number choosen by you depending what info you'd want retrieved, and for values of PWLEN and other - google "define PWLEN".

Thanks a lot of you all.................Please take a glance at my first structure and told me where am i wrong.................... thanks in advance..

Local Const $tagSTRUCT1 = "struct;DWORD var1[100];DWORD var2[100];WCHAR var3[128]; WCHAR var4[128]; WCHAR var5[100]; endstruct"
$rasdialstruct =DllStructCreate($tagSTRUCT1)
DllStructSetData($rasdialstruct,"var1","500")
DllStructSetData($rasdialstruct,"var2","10")
DllStructSetData($rasdialstruct,"var3","as5555")
$fnd=DllStructSetData($rasdialstruct,"var4","Df4456")
DllStructSetData($rasdialstruct,"var5","0")
$Size=DllStructGetSize($rasdialstruct)
MsgBox(0,"",$Size&" Fnd is = "&$fnd)

Happy land ....

@Starstar You can specificate your structure by name index(no using just var string) could be better. somthing like this:

Local $iUserlen=Stringlen("username")
Local $iUserPass=StringLen("userpass")
Local $iDomLen=StringLen("Domain")
$sTagRASCREDENTIALS = "dword dwSize;dword dwMask;wchar szUserName[" & $iUserlen+1 & "];wchar szPassword["& $iUserPass+1 & "];wchar szDomain[" & $iDomLen+1 &"]"

saludos

Onother thing.

When You set data to the structure:

Local $iUserlen=Stringlen("username")
Local $iUserPass=StringLen("userpass")
Local $iDomLen=StringLen("Domain")
$sTagRASCREDENTIALS = "dword dwSize;dword dwMask;wchar szUserName[" & $iUserlen+1 & "];wchar szPassword["& $iUserPass+1 & "];wchar szDomain[" & $iDomLen+1 &"]"

Local $tTRASCREDENTIALS=DllStructCreate($sTagRASCREDENTIALS)



DllStructSetData($tTRASCREDENTIALS,"dwSize",DllStructGetSize($tTRASCREDENTIALS))
;or
$tTRASCREDENTIALS.dwSize=DllStructGetSize($tTRASCREDENTIALS)

;No need pass the number so "10", just 10
DllStructSetData($tTRASCREDENTIALS,"dwMask",10)
;or
$tTRASCREDENTIALS.dwMask=10

#define UNLEN       256                 // Maximum user name length
#define PWLEN       256                 // Maximum password length

You can not just change the size of a structure! The size has to be constant. Use the values 256 as defined in Lmcons.h !

 

Edit:

#define CNLEN       15                  // Computer name length
#define DNLEN       CNLEN               // Maximum domain name length

@funkey I did'nt search that constants. Thank you

Fixed code:

Local Const $UNLEN=256                  ;// Maximum user name length
Local Const $PWLEN = 256                ;// Maximum password length
Local Const $CNLEN =15                  ;// Computer name length
Local Const $DNLEN =$CNLEN              ;// Maximum domain name length

$sTagRASCREDENTIALS = "dword dwSize;dword dwMask;wchar szUserName[" & $UNLEN+1 & "];wchar szPassword["& $PWLEN+1 & "];wchar szDomain[" & $DNLEN+1 &"]"

Local $tTRASCREDENTIALS=DllStructCreate($sTagRASCREDENTIALS)



DllStructSetData($tTRASCREDENTIALS,"dwSize",DllStructGetSize($tTRASCREDENTIALS))
;or
$tTRASCREDENTIALS.dwSize=DllStructGetSize($tTRASCREDENTIALS)

;No need pass the number so "10", just 10
DllStructSetData($tTRASCREDENTIALS,"dwMask",10)
;or
$tTRASCREDENTIALS.dwMask=10

i am trying to calling a dll function but error 5(bad parameter) comes.

Local Const $UNLEN=256
Local Const $PWLEN = 256
Local Const $CNLEN =15
Local Const $DNLEN =$CNLEN

$sTagRASCREDENTIALS = "dword dwSize;dword dwMask;wchar szUserName[" & $UNLEN+1 & "];wchar szPassword["& $PWLEN+1 & "];wchar szDomain[" & $DNLEN+1 &"]"
Local $tTRASCREDENTIALS=DllStructCreate($sTagRASCREDENTIALS)
DllStructSetData($tTRASCREDENTIALS,"dwSize",DllStructGetSize($tTRASCREDENTIALS))
DllStructSetData($tTRASCREDENTIALS,"dwMask",10)
DllStructSetData($tTRASCREDENTIALS,"szUserName","gh1010")
DllStructSetData($tTRASCREDENTIALS,"szPassword","aghh0")
DllStructSetData($tTRASCREDENTIALS,"szDomain","")
$phnbook ="C:\Users\Adnan\AppData\Roaming\Microsoft\Network\Connections\Pbk\rasphone.pbk"
$entry ="hm"
$msg = DllCall("Rasapi32.dll","DWORD","RasSetCredentialsW","wstr",$phnbook,"wstr",$entry,"ptr",DllStructGetPtr($tTRASCREDENTIALS),"BOOl","fClearCredentials")
MsgBox(0,"",$msg[0])

Now What can i do? thanks in advance...........

fClearCredentials should be 'TRUE' or 'FALSE' but no string 'fClearCredentials'.
