ColdFusion function returns space before value

by

I had an annoying issue this morning where a function I wrote that rounds and formats values for use in an internal financial app kept sticking a single space before the value returned. This was obviously not good for a financial app. After spending 10-15 minutes tearing the function’s innards apart it turns out what was going on in the function was not the cause. The cause was simple.

In a tag based ColdFusion function you need to be sure to include the ‘output=”no”‘ attribute.

A LESS Mixin to change font-color based on font-size

by

Just a little LESS fun for the day… Here is a LESS Mixin to change font-color based on font-size.

Green big.
Yellow just right.
Red little.

It can be used with or without passing units (without units will use pixels). Adds bold just for fun.


.colorBySize(@pxValue) when (@pxValue < 12px){ color:red; } .colorBySize(@pxValue) when (@pxValue =< 16px) and (@pxValue >= 12px){
color:yellow;
}

.colorBySize(@pxValue) when (@pxValue > 16px){
color:green;
}

.colorBySize(@_) when not (ispixels(@_)){
font-size: ~"@{_}px";
// font-size: @_;
font-weight: bold;
}

.colorBySize(@_) when (ispixels(@_)){
font-size: @_;
font-weight: bold;
}

p.little{
.colorBySize(9);
}

p.justright{
.colorBySize(12);
}

p.big{
.colorBySize(18);
}

Copy files from one Windows server to another and retain permissions

by

Just want the script?

If you don’t want to read the blah blah blah you can access robocopy-script on Github

I want to know the details…

At my day job I was tasked with migrating several websites and folders from one Windows server to another. The sites have a ton of quirky permissions settings because they are mostly intranet sites. Several have anonymous browsing turned off. As you may or may not know if you just copy them via drag and drop in File Explorer you will lose all of those permissions that took years to refine. Additionally you will lose creation dates, etc.

After some research I determined that Robocopy was what I needed to retain all that valuable cruft information. Unfortunately (or fortunately if you dig command line stuff) Robocopy is a command line tool with quite a few flags. A little more digging revealed there is a GUI for Robocopy which allows you to save scripts, but I decided to roll my own script.

Features:

  • A simple “config” section in the script where you define the to/from locations
  • A config option to run attended or unattended (set this in the script)
  • Logging
  • Utilization of the following flags (descriptions are verbatim from the Robocopy documentation):
    • /E – Copies all subdirectories (including empty ones).
    • /SEC – Copies NTFS security information. (Source and destination volumes must both be NTFS). Equivalent to /COPY:DATS.
    • /COPY:DATSO – Copies the file information specified by copyflags, which can be any combination of the following : D – file Data. | A – file Attributes | T – file Timestamps. | S – file Security (NTFS ACLs). | O – file Ownership information.
    • /V – Produces verbose output (including skipped files).
    • /TEE – Displays output in the console window, in addition to directing it to the log file specified by /LOG or /LOG+.
    • /NP – Turns off copy progress indicator (% copied). **
    • /LOG – Redirects output to the specified file, overwriting the file if it already exists.
    • /B – Copies files in Backup mode (Backup copies are not restartable, but can copy some files that restartable mode cannot). ***
    • /R:10 – Specifies the number of retries on failed copies. (The default is 1 million.)
    • /W:30 – Specifies the wait time between retries. (The default is 30 seconds.)

** I liked seeing the progress as it copied, but all those percentages get written to the log file same as the screen.
*** Consider /Z to use restartable mode.

Obviously you could tweak the flags in the script to get a combination more suitable for you.

If this sounds like something you might find useful you can access robocopy-script on Github. I should note that this is my first public repo on Github. Yay.

Using not() in jQuery to exclude a member of a class

by

This is just a quick tip I thought I throw out there. We have an application that applies a fade to a .alert class on all its pages. We have 2 pages that need to not fade one particular alert. Here is one way it can be handled.

  1. Add a class of .notfade to the alert that needs to stay put and not fade out:
    <div class="alert alert-info nofade"></div>
  2. Place the following in $().ready(): $(".alert").not(".notfade")fadeOut(7000);

RDS Query Viewer not working: How to fix the ColdFusion Builder error: ‘/YOURPROJECTFOLDER/.rdsTempFiles/RDS Query Viewer’ does not exist

by

I have had this issue for a while and it finally made me crazy enough to try to figure it out. It appears that this error occurs when the “RDS Query Viewer” file does not exist in the .rdsTempFiles folder within your project.

On Mac

  1. Open Terminal
  2. Navigate to the directory where your project is located. For example type: cd /Applications/ColdFusion9/wwwroot/YOURPROJECTFOLDER and hit <enter>
  3. If the “.rdsTempFiles” directory does not exist type: mkdir .rdsTempFiles and hit <enter>
  4. If the “RDS Query Viewer” file does not exist type: touch “.rdsTempFiles/RDS Query Viewer” and hit <enter>. BE SURE TO SURROUND THE COMMAND WITH THE DOUBLE QUOTES BECAUSE THE FILE NAME HAS SPACES.
  5. Refresh the “RDS Query Viewer” view. RDS Query View should work now.

On Windows

  1. Open DOS
  2. Navigate to the directory where your project is located. For example type: cd C:\ColdFusion9\wwwroot\YOURPROJECTFOLDER and hit <enter>
  3. If the “.rdsTempFiles” directory does not exist type: mkdir .rdsTempFiles\rdsTempFiles and hit <enter>
  4. If the “RDS Query Viewer” file does not exist type: fsutil file createnew “RDS Query Viewer” 0 and hit <enter>. BE SURE TO SURROUND THE COMMAND WITH THE DOUBLE QUOTES BECAUSE THE FILE NAME HAS SPACES.
  5. Refresh the “RDS Query Viewer” view. RDS Query View should work now.

ColdFusion 9 SELECT IN query using ormExecuteQuery()

by

For some reason this took me some effort to figure out. Maybe others will find it useful.


CategoryList = '1,2,3';
Categories = ormExecuteQuery("from Category where Id IN (:IdList)",{IdList=ListToArray(CategoryList)});

If you know a better way please drop me a comment. I posted this in the Adobe Coldfusion forum for a few days but didn’t get anything.

Adding more resource navigator filters to ColdFusion Builder (Eclipse) Redux

by

There is a post at 12robots.com for how to add resource navigator filters to CFBuilder:

http://www.12robots.com/index.cfm/2010/8/10/Adding-more-resource-navigator-filters-to-ColdFusion-Builder-Eclipse

The solution below is similar, but does not involve accessing .jar files.

Step 1: Locate your version of CFBuilder by selecting “About Adobe ColdFusion Builder 2”.  Make a note of the Version and Build numbers.  For this post I am on Version: 2.0.0 and Build: 277745
Step 2: Locate the plugin.xml file in the com.adobe.ide.coldfusion.rcp_X.X.X.XXXXXX folder (Notice how X.X.X.XXXXXX corresponds to the Version and Build from Step 1):
com.adobe.ide.coldfusion.rcp_2.0.0.277745
Step 2: Locate the following section:
<extension
point="org.eclipse.ui.ide.resourceFilters">
Step 3: Add a block like this for each new filter you want:
<filter
pattern="_notes"
selected="true"/>
Step 4: Start CFBuilder from the command line.  For me on the Mac I execute the following command in Terminal:
"/Applications/Adobe ColdFusion Builder 2/CFBuilder.app/Contents/MacOS/CFBuilder" -clean
Step 5: Enjoy your new navigator filter(s).

Add a last modified date to FW/1 (Framework One) pages

by

Disclaimer:

  1. I’m a total newb to FW/1.
  2. There is most likely a better, or built in way to do this.

Still with me?  Ok.  Here is the specification for this little ditty:

  1. The site I’m working on is mostly static.
  2. It is required (perhaps legally, definitely procedurally) that every page of the site must have a last modified date in the footer.
  3. The site is built using FW/1 (which is awesome).

Here are the cliff notes of what’s about to go down:

  1. I have a footer that is included in every page.
  2. In the footer view Im going to look at the current page’s action in the request context (rc) and figure out what the corresponding “view” is based on the action
  3. I’m going to use cfdirectory to find the lastmodifieddate of the view file from step 2.

Without further adieu:


<!— Start with the path to our views folder —>
<cfset local.viewPath=”#VARIABLES.FRAMEWORK.BASE#views” />
<!— Make an array of rc.action (we use this to append subfolders) —>
<cfset local.arrAction=ListToArray(rc.action,”.”) />
<!— Set the counter to be 1 short of the action array len b/c the last member will be our view page —>
<cfset local.counter=ArrayLen(local.arrAction)-1 />
<!— Set the last member of our action array to be our action page —>
<cfset local.viewPage=”#local.arrAction[ArrayLen(local.arrAction)]#.cfm” />
<!— Append any subfolders to our viewPath —>
<cfloop from=”1″ to=”#local.counter#” index=”local.a”>
<cfset local.viewPath=”#local.viewPath#/#local.arrAction[local.a]#” />
</cfloop>
<!— Look for our viewPage cfm file in our viewPath —>
<cfdirectory action=”list”
directory=”#ExpandPath(local.viewPath)#”
name=”qGetLastdateModified”
filter=”#ListLast(local.viewPage, “/”)#”>
<!— If we have a record count then calculate the last modified date —>
<cfif qGetLastdateModified.recordCount>
<cfset local.siteLastUpdated=’#DateFormat(qGetLastdateModified.dateLastModified,”long”)# at #TimeFormat(qGetLastdateModified.dateLastModified,”hh:mm:ss tt”)#’ />
<cfelse>
<cfset local.siteLastUpdated=”unknown :- (” />
</cfif>
<cfoutput>#local.siteLastUpdated#</cfoutput>

CAPTCHA Fails

by

I was buying some software this morning and got the following CAPTCHA at checkout. CLASSIC.

Yup. For real. My other favorite was one I received while working on an application at the office.

Good stuff.
