We are looking for a way to find the MAC address of a client in Coldfusion.
Is there a way to do this? We are using CF 9 on JDK 1.6 which, I believe, allows us to use the Java network layer, but I would prefer to get be closer to the CFML layer.
You can't get the client's MAC address through java, as it's not passed in anywhere with the request. If you did want it, you would need some code that ran on the client's side. See here for more information: how to get a client's MAC address from HttpServlet?
You are able to get the server's MAC address using the below code as referenced in the answer above.
<cfset LocalHost = CreateObject( "java", "java.net.InetAddress" ).getLocalHost() />
<cfset Mac = CreateObject( "java", "java.net.NetworkInterface" ).getByInetAddress( LocalHost ).getHardWareAddress() />
<cfset MacAddress = '' />
<cfloop from="1" to="#ArrayLen( Mac )#" index="Pair">
<!--- Convert it to Hex, and only use the right two AFTER the conversion--->
<cfset NewPair = Right( FormatBaseN( Mac[ Pair ], 16 ), 2 ) />
<!--- If it's only one letter/string, pad it --->
<cfset NewPair = Len( NewPair ) EQ 1 ? '0' & NewPair : NewPair />
<!--- Append NewPair --->
<cfset MacAddress &= UCase( NewPair ) />
<!--- Add the dash --->
<cfif ArrayLen( Mac ) NEQ Pair>
<cfset MacAddress &= '-' />
</cfif>
</cfloop>
<cfdump var="#MacAddress#" />
I have not done this personally, but here's a link to a forum discussion were they explain how you can do this http://www.raymondcamden.com/forums/messages.cfm?threadid=39CC3269-19B9-E658-9DD1131DAB233CA8 otherwise this should work also http://tutorial17.learncf.com/

I'm in the process of decrypting Chrome's cookie information for a particular website. I can read the data from the file using the SQLLite DB object successfully. The next step is to decrypt the encrypted data.
I've managed to find two Java executables JDPAPI & windpapi4j allowing me to use the Microsoft Data Protection API (MS DPAPI) in Java.
I've loaded both the JAR files in the lib folder and can see their methods as shown below.
I'm trying to pass the encrypted_value of the cookie to the unprotectData and unprotect methods of the Java objects but getting the following error for both of them.
Code:
<cfset a_sqlite = createObject( 'java', 'org.sqlite.JDBC' )>

I believe its something to do with the byte[] input type but not sure how to go about it. Any pointers would be helpful.
My customer is encountering the error The 2 parameter of the Left function, which is now -1, must be a positive integer after migrating from ColdFusion 8 to ColdFusion 10. The page performs as expected in Firefox 31 and Chrome 36 on Windows 7. However, this error occurs in IE9 but not IE7. Are there different security settings in IE9 that prohibit the processing of the code?
The snippet of code in question is:
<!--- Populate the UserInfo struct --->
<cfloop INDEX="item" LIST="#COOKIE.MYELVIS_USERINFO#" DELIMITERS="&">
<cfset delim = #FindOneOf("=",item)#>
<cfif (len(item)-delim)>
<cfset UserInfo[UCase(left(item,delim-1))] = right(item,len(item)-delim)>
<cfelse>
<cfset UserInfo[UCase(left(item,delim-1))] = "">
</cfif>
</cfloop>
I'm torn to say it's a code error when it works in other browsers, just not IE9. Any thoughts? Thank you.
Perhaps have him clear cookies, he might have a holdover from cf 8 and perhaps the two versions encode differently. It looks like, if this is possible, one of the values doesn't contain a =.
Upon reviewing your code, I think this is what you need.
<cfloop INDEX="item" LIST="#COOKIE.MYELVIS_USERINFO#" DELIMITERS="&">
<cfset delim = #FindOneOf("=",item)#>
<cfif (delim) and (len(item)-delim)>
<cfset UserInfo[UCase(left(item,delim-1))] = right(item,len(item)-delim)>
<cfelse>
<cfset UserInfo[UCase(item)] = "">

I recently upgraded a system from CF8 to CF10 and have one bug that I'm having problems tracking down. It has to do with a remote API call that gets a JSON string back and that string then gets converted to a query object. That's where I'm coming across the error:
Element [n] is undefined in a Java object of type class coldfusion.runtime.Array. The problem is in the function that converts the string to a query.
<cffunction name="CFjsonToQuery" access="public" returntype="query" output="no">
<cfargument name="cfData" required="yes" type="struct"/>
<cfset var LOCAL = {}/>
<cfset LOCAL.tmpQry = QueryNew( ArrayToList(ARGUMENTS.cfData.Data.COLUMNS) ) />
<cfloop index = "i" from = "1" to = "#ArrayLen(ARGUMENTS.cfData.Data.DATA)#">
<cfset LOCAL.Row = QueryAddRow(LOCAL.tmpQry) />
<cfloop index="k" from="1" to="#ArrayLen(ARGUMENTS.cfData.Data.DATA[i])#">
<cfset LOCAL.colName = ARGUMENTS.cfData.Data.COLUMNS[K]/>
<cfset QuerySetCell(LOCAL.tmpQry,LOCAL.colName,ARGUMENTS.cfData.Data.DATA[i][k],LOCAL.Row)/>
</cfloop>
</cfloop>
<cfreturn LOCAL.tmpQry/>
</cffunction>
Anywhere the JSON returns 'null' (i.e. "...","19107-3609",null,null,null,"...") the error is thrown. I've tried using isNull to check if it's null in the cfloop:
<cfif isNull(ARGUMENTS.cfData.Data.DATA[i][k])>
<cfset ARGUMENTS.cfData.Data.DATA[i][k] = 'I AM NULL'/>
</cfif>
EDIT - here's a simplified example - the issue is the way the newer deserializeJson() works I believe:
<cfset jstr = '{"SUCCESS":true,"ERRORS":[],"DATA":{"COLUMNS":["ID","FNAME","LNAME"],"DATA":[[390132,"steve",null]]}}'/>
<cfset cfData = deserializeJson(jstr) />
<cfloop index = "i" from = "1" to = "#ArrayLen(cfData.Data.DATA)#">
<cfset Row = QueryAddRow(tmpQry) />
<cfloop index="k" from="1" to="#ArrayLen(cfData.Data.DATA[i])#">
<cfset colName = cfData.Data.COLUMNS[K]/>
<cfset QuerySetCell(tmpQry,colName,cfData.Data.DATA[i][k],Row)/>
</cfloop>
</cfloop>
I've tried all sorts of tests for empty string, isNull etc. and I'm still not sure how to get the query object built if deserializejson returns:
[undefined array element] Element 3 is undefined in a Java object of type class coldfusion.runtime.Array.
This does seem to work:
<cfset cfData = deserializeJson(returnData,'FALSE') />
<cfset qryData = cfData.data />
This lets me then use qryData as if it were a normal cfquery.
You can do a check if the element is undefined using the CF Function ArrayIsDefined(array, elementIndex)
What I've done for now is add 'FALSE' to the deserializeJSON strictMapping flag and that seems to automatically create a query object? I'll admit though this is getting into the underpinnings of CF10 and I could be wrong on that. I'll update my code above for visual clarity.
After moving and backing up my photo collection a few times I have several duplicate photos, with different filenames in various folders scattered across my PC. So I thought I would write a quick CF (9) page to find the duplicates (and can then add code later to allow me to delete them).
I have a couple of queries:-
At the moment I am just using file size to match the image file, but I presume matching EXIF data or matching hash of image file binary would be more reliable?
The code I lashed together sort of works, but how could this be done to search outside web root?
Is there a better way?

This is pretty fun task, so I've decided to give it a try.
First, some testing results on my laptop with 4GB RAM, 2x2.26Ghz CPU and SSD: 1,143 images, total 263.8MB.
ACF9: 8 duplicates, took ~2.3 s
Railo 3.3: 8 duplicates, took ~2.0 s (yay!)
I've used great tip from this SO answer to pick the best hashing option.
So, here is what I did:
<cfsetting enablecfoutputonly="true" />
<cfset ticks = getTickCount() />
<!--- this is great set of utils from Apache --->
<cfset digestUtils = CreateObject("java","org.apache.commons.codec.digest.DigestUtils") />
<!--- cache containers --->
<cfset checksums = {} />
<cfset duplicates = {} />
<cfdirectory
action="list"
name="images"
directory="/home/trovich/images/"
filter="*.png|*.jpg|*.jpeg|*.gif"
recurse="true" />
<cfloop query="images">
<!--- change delimiter to \ if you're on windoze --->
<cfset ipath = images.directory & "/" & images.name />
<cffile action="readbinary" file="#ipath#" variable="binimage" />
<!---
This is slow as hell with any encoding!
<cfset checksum = BinaryEncode(binimage, "Base64") />
--->
<cfset checksum = digestUtils.md5hex(binimage) />
<cfif StructKeyExists(checksums, checksum)>
<!--- init cache using original on 1st position when duplicate found --->
<cfif NOT StructKeyExists(duplicates, checksum)>
<cfset duplicates[checksum] = [] />
<cfset ArrayAppend(duplicates[checksum], checksums[checksum]) />
</cfif>
<!--- append current duplicate --->
<cfset ArrayAppend(duplicates[checksum], ipath) />
<cfelse>
<!--- save originals only into the cache --->
<cfset checksums[checksum] = ipath />
</cfif>
</cfloop>
<cfset time = NumberFormat((getTickcount()-ticks)/1000, "._") />
<!--- render duplicates without resizing (see options of cfimage for this) --->
<cfoutput>
<h1>Found #StructCount(duplicates)# duplicates, took ~#time# s</h1>
<cfloop collection="#duplicates#" item="checksum">
<p>
<!--- display all found paths of duplicate --->
<cfloop array="#duplicates[checksum]#" index="path">
#HTMLEditFormat(path)#<br/>
</cfloop>
<!--- render only last duplicate, they are the same image any way --->
<cfimage action="writeToBrowser" source="#path#" />
</p>
</cfloop>
</cfoutput>
Obviously, you can easily use duplicates array to review the results and/or run some cleanup job.
Have fun!
I would recommend split up the checking code into a function which only accepts a filename.
Then use a global struct for checking for duplicates, the key would be "size" or "size_hash" and the value could be an array which will contain all filenames that matches this key.
Run the function on all jpeg files in all different directories, after that scan the struct and report all entries that have more than one file in it's array.
If you want to show an image outside your webroot you can serve it via < cfcontent file="#filename#" type="image/jpeg">
UPDATED CODE TO LATEST ITERATION
The following function consumes a webservice that returns address details based on zip code (CEP). I'm using this function to parse the xml and populate an empty query with the address details. I would like to know if there is a more elegant way to achieve the same result. It seems to be a waste to create an empty query and populate it...
Any ideas could my method be modified or the code factored/simplified?
<!--- ****** ACTION: getAddress (consumes web-service to retrieve address details) --->
<cffunction name="getAddress" access="remote" returntype="any" output="false">
<!--- Defaults: strcep (cep (Brazilian zip-code) string webservice would look for), search result returned from webservice --->

<cfset var nodes = "">
<cfset var cfhttp = "">
<cfset var stateid = 0>
<cfset var tmp = structNew()>
<!--- Validate cep string --->
<cfif IsNumeric(arguments.cep) AND Len(arguments.cep) EQ 8>
<cftry>
<!--- Consume webservice --->
<cfhttp method="get" url="http://www.bronzebusiness.com.br/webservices/wscep.asmx/cep?strcep=#arguments.cep#"></cfhttp>
<cfset searchResult = xmlparse(cfhttp.FileContent)>
<cfset nodes = xmlSearch(searchResult, "//tbCEP")>
<!--- If result insert address data into session struct --->
<cfif arrayLen(nodes)>
<cfset tmp.streetType = nodes[1].logradouro.XmlText>
<cfset tmp.streetName = nodes[1].nome.XmlText>
<cfset tmp.area = nodes[1].bairro.XmlText>
<cfset tmp.city = nodes[1].cidade.XmlText>
<cfset tmp.state = nodes[1].uf.XmlText>
<cfset tmp.cep = arguments.cep>
<!--- Get state id and add to struct --->
<cfset stateid = model("state").findOneByStateInitials(tmp.state)>
<cfset tmp.stateid = stateid.id>
<cfreturn tmp>
</cfif>
<!--- Display error if any --->
<cfcatch type="any">
<cfoutput>
<h3>Sorry, but there was an error.</h3>
<p>#cfcatch.message#</p>
</cfoutput>
</cfcatch>
</cftry>
</cfif>
</cffunction>
<!--- ****** END ACTION getAddress --->
The calling code:
<!--- Get address data based on CEP --->
<cfset session.addressData = getAddress(cep=params.newMember.cep)>
I can't test this because I don't have an example XML file / CEP to test with, but here is a minor rewrite that addresses four things:
Instead of using cfparam and some strange "params" structure, you should pass the CEP into the function as an argument.
The function shouldn't directly modify session data. Instead, you should return the result and let the calling code assign it to the session (or wherever else it might be needed). I'll show this in a 2nd code example.
Cache the xml result per CEP -- assuming this doesn't change often. (You'll have to improve it further if you want time-based manual cache invalidation, but I can help add that if necessary)
Don't use StructInsert. It's not necessary and you're just writing it the long way for the sake of writing it the long way. There is no benefit.
Again, this isn't tested, but hopefully it's helpful:
<cffunction name="getAddress" access="remote" returntype="any" output="false">

<!--- Validate cep string --->

</cfif>
</cfif>
<!---
<!--- Redirect to page two of the sign up process --->
<cfset redirectTo(controller="assine", action="perfil")>
--->
</cffunction>
Notice that I commented out the redirect you had at the end. That's because with my function, you'll be returning a value, and the redirect should be done after that, like so:
<cfset session.addressData = getAddress("some-CEP-value") />
<cfset redirectTo(controller="assine", action="perfil")>
If you're going to leave out the caching (As you say in a comment you will), then here is a version that makes no attempt at caching:

<cfset tmp.city = nodes[1].cidade.XmlText />
<cfset tmp.state = nodes[1].uf.XmlText />
<cfset tmp.cep = arguments.cep />
<!--- Get state id and add to struct --->
<cfset stateid = model("state").findOneByStateInitials(session.addressData.state)>
<cfset tmp.stateid = stateid.id />
</cfif>
<cfreturn duplicate(tmp) />
<!--- Display error if any --->
<cfcatch type="any">

--->
</cffunction>
Note that I did leave in the use of duplicate(). What this does is return a duplicate of the object (in this case, the struct). This is much more important when you start to work on applications where you're passing complex values into and out of functions over and over again. Using duplicate() causes things to be passed by value instead of by reference. It may not bite you in this case, but it's a good habit to get into.
I would also still use the function argument and return a value -- but it's arguable that this is my personal preference. In a way it is. I believe that a function should be fully encapsulated; a total "black box". You give it some input and it gives you back some output. It should not modify anything outside of itself. (Again, just my opinion.)
So assuming you're using this function as part of a larger multi-step process, you should still use it the same way I've described above. The only difference is that you're setting the session variable outside of the function body. Just as previously:
<cfset session.addressData = getAddress("some-CEP-value") />
<cfset redirectTo(controller="assine", action="perfil")>
That looks pretty straightforward. CF doesn't (yet?) have any magical XML-to-Query functions, but that would be pretty cool. If you wanted, you could probably write up an XSL transform to go from XML to WDDX so that you could use the cfwddx tag ... but that's probably putting the cart before the horse.
You need to move your arrayLen() if block into the try block. As it stands, if the cfhttp tag throws an error, the nodes variable will be a string and not an array, thus causing the arrayLen() to throw another error.
Minor nitpick: I wouldn't add a row to the query until inside the arrayLen() block. That way, the calling code can check recordCount to see if the result was a success.
Beyond that ... that's pretty much how it's done.
