transformation

I have a package that sends out two emails whenever a control flow element fails. For example, if the ExecuteSQL Task fails, the Package level OnError event handler fires two emails. Is this a known issue? How do I get around this? I can do this through database driven scripts, but essentially, I would like to handle the situation on SSIS itself. Thanks for any help. Keep in mind that event handlers will raise events anytime the triggering action occurs. So, you're not guaranteed to only get one event using an event handler (with a few exceptions of course). If you want to guarantee only one

in the above image I have shown two rectangles rectangle 1 whose x can vary from -900 to 13700 and Y can vary from -600 to 6458 rectangle 2 whose coordinate X can vary from 0 to 3000 and y can vary from 0 to 2000 Also: rectangle 2 has its starting point at left top position(0,0) whereas rectangle 1 has starting point( width/2, height/2). What I need to do : to convert a point of rectangle 1 to point of rectangle 2 using scaling or translation. So, what should be scaling factor for x and y coordinates in order to transform the coordinate of rectangle 1 to rectangle 2 ? Matthew Watson If:

I can't quite figure out how to do the following in one line: data(attenu) x_temp = attenu$accel^(1/4) y_temp = log(attenu$dist) best_line = lm(y_temp ~ x_temp) Since the above works, I thought I could do the following: data(attenu) best_line = lm( log(attenu$dist) ~ (attenu$accel^(1/4)) ) But this gives the error: Error in terms.formula(formula, data = data) : invalid power in formula There's obviously something I'm missing when using transformed variables in R's formula format. Why doesn't this work? You're looking for the function I so that the ^ operator is treated as arithmetic in the

I can't understand how scaling and rotation are applied to QGraphicsItem . I need to be able to apply rotation and scaling ( not necessarily keeping aspect ratio ) and I get fully unexpected results. Rotation must be around the item center. I seem to have no problem doing that - yet if I try to debug the bounding rectangle, I get seemingly wrong values. If I don't keep aspect ratio, instead of rotation I get a very weird skew, and I have been struggling for quite a while to find the cause and correct it. I hope anybody can find a solution. For many items - like rectangles - my solution was to

I'd like to use the new VS2010 web.config transformation feature to change the connection string within the nhibernate configuration in my web.config file. The relevant snippet is something like this: <?xml version="1.0"?> <configuration> <configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" /> </configSections> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class"

TL;DR: Is there a way how to specify the order in which the Babel plugins are supposed to be run? How does Babel determine this order? Is there any spec how this works apart from diving into Babel sources? I'm developing my own Babel plugin. I noticed, that when I run it, my plugin is run before other es2015 plugins. For example having code such as: const a = () => 1 and visitor such as: visitor: { ArrowFunctionExpression(path) { console.log('ArrowFunction') }, FunctionExpression(path) { console.log('Function') }, } my plugin observes ArrowFunction (and not Function). I played with the order
