Hello.

 

I don't know, whether a typo or not, but you need to input the variables (e.g. $szEntryName) and not their names into the DllCall function.

 

The return variable of the RasSetEntryDialParams function is a dword variable, the "ERROR_SUCCESS" is one possible value of it. (when everything went ok, this is the return value)

 

The second parameter of the RasSetEntryDialParams function is a pointer to a RASDIALPARAMS structure, so you have to create it before calling the function.

 

I encourage you to browse the following Autoit Help topics:

http://www.autoitscript.com/autoit3/docs/functions/DllCall.htm

http://www.autoitscript.com/autoit3/docs/functions/DllStructCreate.htm

(don't get me wrong, if I misjudged your Autoit and programming skills...)

 

That's what I can help you.

May the experts answer your post, and direct you to the good direction.

 

Best regards. CiV

Good way to learn how to work with DllCall and API is to look at working sources in standard include files and compare DllCalls from there with their MSDN documentation.

HMm......It is a Point...

Your call should end up looking something like this.

DllCall("Rasapi32.dll", "dword", "RasSetEntryDialParams", "wstr", $lpszPhonebook, "ptr", DllStructGetPtr($rasdialparams), "bool", $fRemovePassword)

$rasdialparams is a structure which can be built by studying it here.

Thanks JohnOne.......

[Starstar]

$lpszPhonebook = @AppDataDir& "\Microsoft\Network\Connections\Pbk\rasphone.pbk"
$szEntryName="HM-LINK"
$szUserName="AAa"
$szPassword="wadf"
Local Const $tagSTRUCT1 = "struct;int dwSize;CHAR szEntryName[RAS_MaxEntryName + 1];CHAR szUserName[UNLEN + 1];CHAR szPassword[PWLEN + 1];CHAR; endstruct"
$rasdialparams = DllStructCreate($tagSTRUCT1)
DllCall("Rasapi32.dll", "dword", "RasSetEntryDialParams", "wstr", $lpszPhonebook, "ptr", DllStructGetPtr($rasdialparams),"CHAR",  $szEntryName, "CHAR", $szUserName, "CHAR", $szPassword)
If @error Then
    MsgBox(0,"","Error in DllCall "&@error)
    EndIf

i am trying like this But i could not success.......Please Help Me. If anyone Knows about this......

[CiVQ]

Well, I don't know about the windows dialing API, but your structure is badly defined for sure.

It should be something like this:

Local Const $tagSTRUCT1 = "struct;int dwSize;CHAR szEntryName["&$RAS_MaxEntryName + 1&"];CHAR szUserName["&$UNLEN + 1&"];CHAR szPassword["&$PWLEN + 1&"];CHAR; endstruct"

You should to find out by yourself, how to get $RAS_MaxEntryName (maybe the count of current items in hold);

$UNLEN may be StringLen($szUserName) or the maximum accepted name length, or something else;

so as $PWLEN.

Thanks CiVQ....But my Problem still remain....

Zedna Thanks a lot of you............

Does it work?

Because I didn't test it I just corrected your AU3 syntax (from deleted post) according to MSDN description.

Hints:

Post what you have tried to get more help on this forum
