Hi list, Despite the question I asked last time (I will re-install the FC3 with Samba 3.0.14a on another computer for replacement soon), I still have one more question on Excel files. I found that Excel file opening is extremely slow (especially on slow connections, i.e. VPN). The case is really bad, it takes around 2 mins to open a excel file of around 400k. Actually we got both side having

Does anyone know if there are any reseller for the book "VoIP Telephony with Asterisk" in Hong Kong/Asia region? I'm interested in purchasing the book but the shipping charge to Hong Kong is expensive. Thanks. Joseph -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, first thanks to Sunny Ho (and David James for the pointer) for resolving the problem of the empty rows returned from ROracle.

Hi: i am surveying ip phones for our company. we will use them with asterisk. we have office in taiwan, hong kong,singapore and china. cisco and polycom are too expensive for us. we try several china brand ip phones. they are all cheap and some of them have good quality. but most of them won't offer future firmware support, which we think it's important for ip phones.

Dear David, Thanks for your prompt reply! Sure, I can implement a AST visitor to go through the AST to get the information but I just wonder whether there is any other way to let Clang do so. What I am considering is how to let the generated IR looks like below, which some tools realize: define dso_local i32 @_Z1fPii([51 x i32]* %A, i32 %x) local_unnamed_addr #0 !dbg !7 { entry: ...

Hello, Quick observation after recently updating all DC's to 4.2.0 from 4.1.17. Several users received the notice "account is currently locked out" after entering their password once. I updated the policy to a minimum of 3 attempts before any user logged in initially. I opened Microsoft ADUC tool and clicked the box to unlock their account. This resulted in the user receiving

Dear all, Hi! Recently, I notice a situation where I cannot infer the size of the outermost dimension of array in the function interface. To concretely depict the problem, I show the C source code and the generated IR code at the end. The array size of A[] is 51 but this information is lost in the generated IR. How can I maintain such information in IR? Should I set some argument for

Dear all, I write a new LoopPass which wants to use passes including LoopInfoWrapperPass, ScalarEvolutionWrapperPass and LoopAccessLegacyAnalysis.

Hi, I have a char vector with year values. Some cells have single year value '2001-' and some have range like 1996-2007. I need to remove hyphen character '-' from all the values within the character vector named as 'end'. After removing the hyphen I need to get the last number from the cells where there are year range values i.e if the cell has range 1996-2007, the code

To whom it may concern: The help page for ?legend refers to a `title.cex` parameter, which suggests that the function has such a parameter. As far as I can tell, though, it doesn't; here's an example: > plot(1,1) > legend("topright",pch=1, legend="something", title="my legend", title.cex=2) Error in legend("topright", pch = 1, legend =
