firefox - Barcode scanner causes chrome manifest error in FF, when typing doesn't? -


We have an EVO laser USB barcode scanner, and when we do some scans, my web app (type?) Breaks If we type in the same thing, then there is no problem. In fact, the scan is successful, and typing in numbers from the barcode, and it brings it to the next page in sequence. The difference is that the barcode scanner pops up the browser error with the following error:

Browser Console Error

It is consistent: Typing works, but the scanner decides the error. I thought the computer could not tell ... how is it on firefox-specific error causing the earth? (FF28.0 Clean Stock Install.)

It happens, my app was a port of desktop old After app scanning created around the scanner, the old scanner did not emit any particular character, so the desktop app will automatically respond after typing / scanning the number of precise digits. I have worked the webapp port in the same way, however, the use of new scanners is being released after scanning CRLF, due to which FF can already write some javascript call form.submit () Try to have enough letters to be typed. I do not think the FF should react with the "above" error, but the solution was simple, disable barcode reader's feature so that it emits CR and LF after successful scan. (Even at 1ms intervals delay, it works fine.)

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
