Passing Parameters in both FireFox and IE

showModalDialog will only work in IE. It's not clear what the relationship is between your Admin forms but have you thought of using Cookies to write out values from one form and read them from the other?

The cookie solution is not too tricky to impliment once you get your head around it.

The 'launching' form needs a VBScript and a Jscript. Put a button on the admin form which runs the NewCookie script when pressed. The script reads data from fields on the form, stores it in a cookie then launches the target form.

First - the VBScript:

function NewCookie()
' First Create a string of text from the fields you want to pass across
' Fields are delimited by !! but this can be anything which does not appear in the data
    Dim AdminCookie
    AdminCookie = "!!" & GetField("Field1")
    AdminCookie = AdminCookie & "!!" & GetField("Field2")
    AdminCookie = AdminCookie & "!!" & GetField("Field3")
    AdminCookie = AdminCookie & "!!" & GetField("Field4")& "!!"

 ' Next line calls the SaveCookie function which is defined below
    SaveCookie "AdminCookie", AdminCookie

 ' Next line calls a JScript function which actually launches the admin form
    Call OpenAdminForm()
End function

function SaveCookie(VarName,VarValue)
    If len(VarValue) >= 1 Then
        Document.Cookie = VarName & "=" & VarValue & ";" &  "expires=" & Date()+1
    Else
        Call Delete_Cookie(VarName)
    End If
End function

Next the JScript which is called from the above:

// Launches the admin form
function OpenAdminForm()
{
var LaunchURL
LaunchURL = "http://ServerName/Metastorm/eForm.aspx?Map=Admin-Form-Group-Name&Client=External&Action=Admin-Form-Name"
window.open(LaunchURL,'_blank','resizable=yes,scrollbars=yes');

}

The 'target' form needs some JScript which will read the cookie from disk whenever it loads. On this form call the function ReadCookie from the on form load property.

// Read Cookie details
function ReadCookie()
{
// This line populates a variable called AdminCookie with the contents of the cookie read by the GetCookie function below
    var AdminCookie = GetCookie("AdminCookie");

// If the cookie is found the next section splits it into an array of fields using the !! delimiter
// then sets fields on the admin form accordingly.
    if (AdminCookie || 0) {
    var AdminDataArray;
        AdminDataArray = AdminCookie.split( "!!");

    SetField("Field1", "Value", AdminDataArray[1]);
    SetField("Field2", "Value", AdminDataArray[2]);
    SetField("Field3", "Value", AdminDataArray[3]);
    SetField("Field4", "Value", AdminDataArray[4]);

// Finally call the delete cookie function to clear the cookie 
    delete_cookie("AdminCookie","");
}
}

// This function actually reads the cookie in from disk.

function GetCookie(name) {
    var cookie = " " + document.cookie;
    var search = " " + name + "=";
    var setStr = null;
    var offset = 0;
    var end = 0;
    if (cookie.length > 0) {
        offset = cookie.indexOf(search);
        if (offset != -1) {
            offset += search.length;
            end = cookie.indexOf(";", offset)
            if (end == -1) {
                end = cookie.length;
            }
            setStr = unescape(cookie.substring(offset, end));
        }
    }
    return(setStr);
}

//This function deletes the cookie.

function delete_cookie (name, path)
{
    var expiration_date = new Date ();
    expiration_date.setYear (expiration_date.getYear () - 1);
    expiration_date = expiration_date.toGMTString ();

    var cookie_string = escape (name) + "=; expires=" + expiration_date;
    if (path != null)
        cookie_string += "; path=" + path;

    document .cookie = cookie_string;
}

Hope this is helpful
