11/14/07 5:35 PMDSAPI Filter code for Notes Domino

Here's another nugget of Notes API code that I am slowly releasing into the wild. I'm not sure that it even has meaning in today's Domino world, but what the hey.

In this case its a DSAPI filter I wrote which basically instructs the browser to not cache anything that might come from the mail directory. The problem with this type of instruction is that the browser and any proxy server between the server and the browser can just ignore the "Suggestion" and cache whatever it wants anyway.

In the code, I thank Chris Stead. Unfortunately, I can't remember who this person is specifically, and what parts of the code I borrowed from Chris. I think I borrowed the overall structure of the DSAPI code from Chris and then built in the specific functionality I was looking for.

11/7/07 9:40 AMEnforce Consistent ACL - Code released into the wild

Somebody asked me for this today, since my old domino based blog entries are no longer available online.

Here is the C++ Lotus API code I wrote to toggle the SetUniformAccess flag on a database, also known as the Enforce Consistent ACL flag. This does require the C++ dll on your path, such as lcppn23.dll or later.

#include <lncppapi.h>
#include <iostream.h>

int main(int argc, char *argv[])
{
	char errorBuf[LNERROR_MESSAGE_LENGTH];
	LNNotesSession session;
	LNSetThrowAllErrors(TRUE);

	if ( argc < 2 )
	{
		cout << "This application sets the SetUniformAccess flag" << endl;
		cout << "Also known as the EnforceConsistentACL flag" << endl;
		cout << "Usage: " << endl;
		cout << "     DbSetUniformAccess.exe database flag" << endl;
		cout << "          -database = path to database to change" << endl;
		cout << "          -flag = T to set to true, anything else to set to false" << endl;
		return(0);
	}

	

	try {
		session.Init();
		LNDatabase db;
		LNACL acl;
		char * testchar = "T";

		cout << "Opening database: " << argv[1] << endl;
		session.GetDatabase(argv[1], &db);
		db.Open(LNDBOPENFLAGS_NO_USER_INFO);
		db.GetACL(&acl);

		if (strcmp(argv[2], "T") == 0)
		{
			acl.SetUniformAccess(TRUE);
			cout << "changed SetUniformAccess to TRUE" << endl;
		}
		else
		{
			acl.SetUniformAccess(FALSE);
			cout << "changed SetUniformAccess to FALSE" << endl;
		}

		acl.Save();
	}
	catch (LNSTATUS error) {
		LNGetErrorMessage(error, errorBuf);
		cout << "Error:   " << errorBuf << endl;
	}

	cout << "Finished running" << endl;
	session.Term();
	return(0);
}
      

8/6/07 2:22 PMConvert a String to a number in Javascript

Here's one for the memory banks. I wanted a simple way to convert a string into a number. The built in parsing functions in Javascript don't deal with negatives at all. My String could look like "200px" or "-200px". calling parseInt on 200px would work fine and return 200, but -200px would return NaN. So with a little hackery I came up with this:

newNumber = someString.split(/[^0-9\-]/).join('');

Regex sure provides some crazy fun eh?

Anyway, you might have noticed that it doesn't deal with decimals. Something like /[^0-9\-\.]/ might do it, give it a whirl.

7/3/07 1:26 PMJSF is Half Baked

Someone, please put it back in the oven.

Here is my thought for today: The person that dreamed up the whole representation of a select tag should be shot.

They have made it impossibly hard to implement a stupid frickin HTML Select tag. So I decided to look at the Tomahawk option. The sample on the apache website for the t:selectItems shows it being used with a standard h:selectOneMenu. However, my Facelets taglib for Tomahawk does not include a selectItems and does include its own selectOneMenu.

This crap is so not ready for primetime. We are using 3 layers of code (Facelets, Tomahawk, and JSF) and none of them are anywhere near ready to be used.

Don't even get me started on the stupid dataTable.

Arrrrrgggghhh!

Here's one for the knowledge base. If you want to increase the max memory available to Eclipse, or basically tinker with any of the other command line parameters that our Winders brethren manipulate via their application shortcut, you need to do the following.

Wherever it was that you installed Eclipse, navigate into the application package contents using either the "Show Package Contents" option in the Finder or simply via the terminal.

You need to edit the file ...Eclipse.app/Contents/MacOS/eclipse.ini. To change the memory available, update the parameter -Xmx. To set max memory to 512MB you would put -Xmx512m.
