My application is too slow in PPA

[Guest]

Hi,guys
I have a application developed by vb.net, including two form, in the main
form, I used 50 picture button. when I drawed the form, it's very slow.
And run other functions are very slow too, but these function just run in
the behind, not to draw. Why?

I have a similiare application coded by evb, It's more fast than this one,
How can I do to increase my application speed?

sample
I caculate the ten products tax, in evb need 0.1 second, now I need 1 second.

Compile your project in release mode and use the stopwatch (in
opennetcf.diagnostics) to find exactly how long each method takes. Then post
the code for the slowest method to see if anyone has optimisation
suggestions.

Since you are using VB, if you are not already using the SDF see here for
the stopwatch:
