ok - long story short. have e-comm site hosted on windows vps using sql server 2005, site been years , works fine. i trying set new site hosted on windows vps server share same database. both sites using classic asp , have put duplicate page each server has simple sql query display product name on screen. on new site 500 error listed below: get /testconnection.asp |49|800a0bb9|arguments_are_of_the_wrong_type__are_out_of_acceptable_range__or_are_in_conflict_with_one_another. line 49 in code is: rsproddetail.open sql, cnn, adopenforwardonly, adlockreadonly, adcmdtext as mentioned page identical on 2 servers. adovbs.inc there , path file include correct on new server. where next? have tried using rsproddetail.open sql, cnn, 0, 1, 1 to see if ado constants defined correctly ?

i have import flat files sql server. far, i've used ssis packages , delphi programs job i'm getting more , more files load. many wide (more 90 fields) , have own specifics: fixed-width, delimited wide set of characters used field , row delimiter, use "always insert" pattern while others use "update or insert", etc. many of these files several gigabytes in size making harder handle them. now i'm starting wonder if there isn't better way handle this: tool dedicated doing kind of work used in rational way: ssis nice but, frankly, use of gui 99% of work makes impractical when dealing non-trivial tasks. would care suggest solution ? you may use format file bulk load. description: http://msdn.microsoft.com/en-us/library/ms189636.aspx

ok, not sure if title accurate, open suggestions! i in process of creating asp.net custom control, still relatively new me, please bear me. i thinking event model. since not using web controls there no events being fired buttons, rather manually calling __dopostback appropriate arguments. can mean there lot of postbacks occuring when say, selecting options (which render differently when selected). in time, need make more ajax-y , responsive, need change event binding call local javascript. so, thinking should able toggle "mode" of control, can either use postback , handlle itself, or can specify javascript function names call instead of dopostback. what thoughts on this? am approaching raising of events control in wrong way? (totally open suggestions here!) how approach similar problem? edit - clarify i creating custom rendered control (i.e. inherits webcontrol). we not using existnig web controls since want complete control on rendered output. afai...

let's i'm writing function convert between temperature scales. want support @ least celsius, fahrenheit, , kelvin. better pass source scale , target scale separate parameters of function, or sort of combined parameter? example 1 - separate parameters: function converttemperature("celsius", "fahrenheit", 22) example 2 - combined parameter: function converttemperature("c-f", 22) the code inside function counts. 2 parameters, logic determine formula we're going use more complicated, single parameter doesn't feel right somehow. thoughts? go first option, rather allow literal strings (which error prone), take constant values or enumeration if language supports it, this: converttemperature (tempscale.celsius, tempscale.fahrenheit, 22)

i have graph object (this in perl) compute transitive closure (i.e. solving all-pairs shortest paths problem). from object, interested in computing: shortest path vertices u -> v. distance matrix vertices. general reachability questions. general graph features (density, etc). the graph has 2000 vertices, computing transitive closure (using floyd-warshall 's algorithm) takes couple hours. caching serialized object (using storable , it's pretty efficient already). my problem is, deserializing object still takes fair amount of time (a minute or so), , consumes 4gb of ram. unacceptable application. therefore i've been thinking how design database schema hold object in 'unfolded' form. in other words, precompute all-pairs shortest paths, , store in appropriate manner. then, perhaps use stored procedures retrieve necessary information. my other problem is, have no experience database design, , have no clue implementing above, hence post. i'd...
