Print out a variable name

[Shaggi]

AutoIt does (did) keep track of variable internally of course, but the functions to work with it are not public facing:

AUT_RESULT AutoIt_Script::F_Eval(VectorVariant &vParams, Variant &vResult)
{
    bool    bConst = false;

    if (g_oVarTable.isDeclared(vParams[0].szValue()))
    {
        Variant *pvTemp;
        g_oVarTable.GetRef(vParams[0].szValue(), &pvTemp, bConst);
        vResult = *pvTemp;
        return AUT_OK;
    }
        ...
}

the function calls an internal GetRef method:

bool VariableTable::GetRef(AString sVarName, Variant **pvVariant, bool &bConst, int nReqScope)
{
    Variant *lpVar = NULL;

    sVarName.toupper();                         // Always use uppercase to force case insensitive operation

    switch (nReqScope)
    {
        case VARTABLE_ANY:
            if (!m_Locals.empty())
                lpVar = m_Locals.top()->findvar(sVarName.c_str(), bConst);

            if (lpVar == NULL)
                lpVar = m_Globals.findvar(sVarName.c_str(), bConst);

            break;

        case VARTABLE_FORCELOCAL:
            if (!m_Locals.empty())
                lpVar = m_Locals.top()->findvar(sVarName.c_str(), bConst);
            else
                lpVar = m_Globals.findvar(sVarName.c_str(), bConst);

            break;

        case VARTABLE_FORCEGLOBAL:
            lpVar = m_Globals.findvar(sVarName.c_str(), bConst);
            break;
    }

    *pvVariant = lpVar;

    return (lpVar != NULL);

} // GetRef()

Which calls the findvar method on the appropriate variable scope:

Variant* VariableList::findvar(const char *szName, bool &bConst)
{
    VarNode *lpTemp = findvarnode(szName);

    if (lpTemp)
    {
        bConst = lpTemp->bConst;
        return lpTemp->pvVariant;           // Found!  Return a pointer to it
    }
    else
        return NULL;

} // findvar()

Which in turn uses findvarnode to get the NODE pointer:

VarNode* VariableList::findvarnode(const char *szName)
{
    VarNode *lpTemp = m_lpRoot;
    int nRes;

    while (lpTemp != NULL)
    {
        nRes = strcmp(lpTemp->szName, szName);

        if (nRes < 0)
            lpTemp = lpTemp->lpLeft;            // Less than (left child)
        else if (nRes > 0)
            lpTemp = lpTemp->lpRight;           // Greater than (right child)
        else
            return lpTemp;                      // Found
    }

    // Not found
    return NULL;

} // findvarnode()

This is off the last public version of the source code. The underlaying issue is simply that there doesn't seem to be a public facing function for findvar. In "userland", the global vs public scope get messed up when you try to pass a global variable to a local function (the variable is copied by value or at least via reference, so the global variable name is not preserved in the local scope...), so I don't think it's possible to pass just a variable, it would have to be the name as a string like the examples aboves.

I hope this is changed to a hash check instead of a strcmp * amount of variables.. lol

Hello everyone,

I am sorry i dono where to post my question. so posting it here.

I just wanted to know whether we can send a variable to the AutoIT executable file from Selenium.

Here is my java script to call the AutoIT

String FileName = Driver.findElement(By.id(

"PaycostProcess")).getAttribute("id") ;

System.

out.println(FileName);

String FileName2 =FileName +

" - " + "Australia";

System.

out.println(FileName2);

String[] FileName3 =

new String[] {FileName2};

Runtime.getRuntime().exec(

"C:Users349805DesktopDownload1 - autoit.exe", FileName3);

Here is the Auto It Script:

WinWaitActive("Windows Internet Explorer")
WinActivate("Windows Internet Explorer")

Sleep(1000)
Send("!a")
Sleep(1000)

ControlFocus("Save As", "", "[CLASS:Edit; INSTANCE:1]")
Local FileName = FileGetLongName(FileName3)

Send(FileName)
Sleep(1000)

Send("!S")

 

While Processing it is throughing the error

No Variable given for "Dim", "Local", "Global", "Struct" or "Const" statement. in Line 7.

Could you please tell me how to get the parameter in AUTOIT.

Thanks in Advance.

Ok, I know it is a bit old, but i had same problem and found how to do it without over coding so there is my solution for the printing variable value and name, hope someone will find it useful.

Func VariableChecker($VariableName, $VariableValue)
    SplashTextOn("Variable Checker", @CRLF &@CRLF & "Status of " & @CRLF &@CRLF & $VariableName & " is: " & $VariableValue , 300,200)
    Sleep(5000)
    SplashOff()
EndFunc

now just call it like so:

VariableChecker("$MyVariableToBeChecked", $MyVariableToBeChecked)
