Wrong result from IsNumeric() in VB.NET -

-

i have function in vb.net loops through values , attempts convert decimal if isnumeric true,

dim value string  if isnumeric(value) = true     rate = ctype(value, decimal)  <--- bombing here end if

i've found when function receives value 603e43 isnumeric evaluates true reason , bombs on conversion. why isnumeric true in case?

see http://support.microsoft.com/kb/329488

isnumeric returns true if can converted double true 603e43 value larger decimal can hold

you use decimal.tryparse funcion working alternative. see http://msdn.microsoft.com/en-us/library/9zbda557.aspx

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
