Why everything in WPF is blurry?

阅读更多关于 Why everything in WPF is blurry?

问题 Can someone explain why everything in WPF is blurry? Is this something that can be fixed? 回答1: The reason for this is the anti-aliasing system which spreads the line over multiple pixels if it doesn't align with physical device pixels. WPF is resoultion independent. This means you specify the size of an user interface element in inches, not in pixels. A logical unit in WPF is 1/96 of an inch. This scale is chosen, because most screens have a resolution of 96dpi. So in most cases 1 logical

Clarity: Is there a recommended way to make clr-datagrid take up all available vertical space?

阅读更多关于 Clarity: Is there a recommended way to make clr-datagrid take up all available vertical space?

问题 I am trying to make my take up all vertical space even if there are no rows in the table yet. Is clr-datagrid customizable to do so? It seems like I have to manually override flexbox properties of .datagrid-host and .datagrid-overlay-wrapper in order to make it grow in column direction. I tried even that but the datagrid don't seem to be growing vertically. 回答1: The Clarity datagrid supports any fixed height you want on the datagrid element itself. If the height is too large for the number of

Check if variable null before assign to null?

阅读更多关于 Check if variable null before assign to null?

问题 Is variable assignment expensive compared to a null check? For example, is it worth checking that foo is not null before assigning it null? if (foo != null) { foo = null; } Or is this worrying about nothing? 回答1: This is a micro-micro-optimization (and possibly something handled by the compiler anyways). Don't worry about it. You'll get a far greater return by focusing on your programs actual algorithm. We should forget about small efficiencies, say about 97% of the time: premature

How can I solve socket closed when report takes long-time to run?

阅读更多关于 How can I solve socket closed when report takes long-time to run?

问题 I am running reports in Clarity made with iReport. One of my reports is quite complex and sometimes takes a long time to run (depending on parameters). Sometimes, it takes too long and I get a message that says Socket Closed This message does not appear when the report runs quickly. I would assume that this means that the run has timed-out. I am currently working to make the SQL run faster, but I fear it will still not be before the time-out. Is there anyway to make the socket stay open
