Client Access Hotspots

October 11, 2002 Timothy Prickett Morgan

Hey, Ted:

I want to display a calendar if a user clicks on a date on the first line of a display. The date field is a ten-character output field in mm/dd/yyyy format.

If I click on the year or a forward slash (/), the program works correctly. However, if I double-click on the month or date portion, the program goes crazy. Double-clicking on a date of 03, for example, shuts down the program. Double-clicking on a month of 10 locks the keyboard.

Any ideas you have that will help solve my problem will be greatly appreciated.

Reader Feedback and Insights: QTEMP and the Library List

October 9, 2002 Timothy Prickett Morgan

Hey, Ted:

In the June 5 issue of Midrange Guru, a reader ended an explanation of a technique for specifying QTEMP in library lists with this statement: “. . . I suggest that QTEMP should ALWAYS be placed at the bottom of the library list and that references to files in QTEMP should ALWAYS be hard coded.”

There seems a chance of contradictory behavior with that. If references to QTEMP are always hard coded, then perhaps QTEMP should not be in the library list.

And if QTEMP must be in the list in order to catch possible *LIBL references,

FTP and Save Files, Yet Again!

October 9, 2002 Timothy Prickett Morgan

Hey, Ted:

I have a further refinement to Sami’s tip [ “FTP and Save Files”, Midrange Guru, OS/400 Edition, October 2 ].

You get much better compression if you compress on the PC, using PKZIP. I tried a small library:
```
 393K - No compression
 242K - DTACPR(*YES)
 116K - DTACPR(*NO), PKZIP'ed
 117K - DTACPR(*YES), PKZIP'ed
```
Of course, this assumes that the recipient can unzip the file, but nearly everyone has PKZIP or WinZip or some variant.

It’s interesting to note that you usually get the best compression by saving with DTACPR(*NO) and letting PKZIP do its thing on the

Using APIs to Send Impromptu Messages

October 9, 2002 Ted Holt

Hey, Ted:

I would like to use the error message APIs QMHRMVPM and QMHSNDPM in an RPG IV program to send messages to an error-message subfile.

I do not want to have to define the messages in a message file. I would prefer to use constant definitions from within my RPG program. Is this possible?

I’ve searched written manuals and have not yet found a way to do this.

— Russell

Any message that is not sent as an *ESCAPE, *STATUS, or *NOTIFY message can be sent as an impromptu message, Russell. Here’s a short program you can play with. …

Find the Cursor Position in a CL Program

October 4, 2002 Timothy Prickett Morgan

Dear Readers:

In the September 27 issue of Midrange Guru, my friend Holley Davis shared one method for returning the cursor location to a CL program. In this issue he shares a second method.

— Howard

There are two ways to tell where the cursor is located in a CL program. Both of them require you to add the RTNCSRLOC keyword to your display file as shown in the example below.

The RTNCSRLOC has two formats. You can use either one or both as needed. One format uses three variables to relay information from the display file to

David’s Choice for Java Error Logging

October 4, 2002 Timothy Prickett Morgan

Hey, David:

Thanks for all the tips you have given us. You have saved us countless hours of frustration. In return, here is a tip for you.

Where I work, we were trying to decide how to log errors and other diagnostic messages from our Java applications.

With all the choices (i.e., LogKit, Log4J, JDK14), we were not sure what was best.

We knew we needed something, but did not want to lock ourselves into a logging framework that would not meet our needs.

That was when we found that the Jakarta-Apache project (http://jakarta.apache.org) had a project that

When Good Batch FTP Users Go Bad

October 2, 2002 Timothy Prickett Morgan

Hey, Joe:

I set up a Windows batch FTP script to automatically transfer files from my iSeries box to a Windows desktop. I set up this transfer to occur every Friday evening. This week, the batch transfer stopped working because the remote OS/400 FTP server rejected the FTP user profile and password in the script. The strange thing is that the OS/400 FTP user profile is still enabled on the server. Any ideas what’s happening here?

— Al

To get an idea of what’s going on, let’s examine the following sample Windows batch FTP script from a recent article on
