Posted http://quality.runrev.com/show_bug.cgi?id=14793, with updated example stack with lots of ways to experiment.

Hi! Probably an easy one - searched for an answer but didn't find it. I have fields (effectively standardized, or template fields I use in multiple stacks) whose content can be changed, either manually or programmatically. I have "standard" template scripts for validating certain input types, and po...

Thanks Jacque. So there is A) no way to create a graphic at 1 pixel resolution, and B) that's not a bug or improvement required issue? I do not believe subpixel rendering is the issue. I have 94 vertical addresses between top and bottom, the code executes 94 lines at 1 pixel width in the repeat loop...

Aha! A third version - this one you can select either the gradient colors to be drawn or random color selection for each line. If you use a dragSpeed under say 1000, it is very informative. It appears that lines are only printing on alternate addresses, in other words a line is drawn (1 pixel wide) ...

Here's a new version which has a log field. In both cases of lineWidth (1 and 2 pixels) the same number of lines are drawn, but when drawn with a slow dragSpeed, it appears that every second line is drawn out side the graphic, even though the coordinate values are correct.

The attached stack draws a color gradient between two colors, one line at a time. The number of lines in the gradient is the height of the graphic object. The "lineWidth" is set to either 1 or 2. A line size of one, which should fill the graphic, instead only draws every other line visually, althoug...

Currently, if you enter a value greater than 65535 as a "dragSpeed", execution fails and an error is thrown. I see that it indicates that 65535 is the maximum value in the documentation, but should it throw an error? The documentation does not say it will. I vote that it is an unhandled exception to...

So this:

should be reposted there for discussion?

Ahh, OK. I've only seen basic "How to use LC with DBMS" kinds of information. Someone else may know more.

Hi Dominatio. Search online for "asynchronous mirroring", "log shipping", "intermittent database update propagation" (there are probably more relevant key phrases). There are some good entries from IBM, MS, SQL, and others. I think it's more an application architecture issue than an LC coding issue....

Here is a more detailed demonstration stack. The explanations are in the stack. Basically two fields, one using "the clickLine", and one assigning "the clickLine" to a local variable. Tested on Win7 x64 LC 5.5.5, 6.6.2, and 7.0.1, differences noted in stack. Questions raised: 1. Should "Answer" clea...

Using 7.0.1 Community on Win7 X64 this code in a field: on mouseUp local tClickLine put the clickLine into tClickLine delete tClickLine end mouseUp ignores the delete command completely (about half of the time) or produces: field "fRGB": execution error at line n/a (Object: stack locked, or object's...
