How can i create Dllstructure??

[Starstar]

How to use "DllStructCreate"? Any hint will be appreciated and thanks in advance........

Edit::

i had also see autoit help file many times and other related topic but i couldn't learn it properly.

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?

[Starstar]

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..................

Danyfirex Thank a lot of you..............

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  

[trancexx]

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".

thank trancexx very helpful.........

[Starstar]

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 &"]"

This is very usefully for me

very very useful............

[Danyfirex]

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

@trancexx is dot access safe as dllstructureset/readdata?

[funkey]

#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

[Danyfirex]

@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

Good.........

[Starstar]

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...........

[funkey]

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

[Starstar]

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

 

i have also tried like this but result is same..........i always get error 5.
