c++ - Win 32 API in Qt -


I have a program using MFC to communicate with Ethernet on a device. I have to type it again and it should be converted to QT

The MFC program uses Win API functions such as CreateFile, ReadFile (to get network packets) and DeviceIOControl (the protocol used to facilitate communication To talk)

Can I use these functions - CreateFile, ReadFile and DeviceIOControl directly in my QT code if I include Windows.h?

How about Win API functions used for concurrency, such as WaitForSingleObject and Mutex? What part of Win API / Q is not available in Q?

Is there a standard mechanism for converting MFC code to Qt?

Can I use these functions - CreateFile, ReadFile and my DeviceIOControl directly if I include Windows.h?

Yes.

How about using Win API functions for transition, such as WaitForSingleObject and Mutex? Which part of the Win API is not available in QT?

You can use any part of Win API.

Is there any standard mechanism to convert the MFC code to QT

is not a standard system, however, for the above functionality, you actually have the Qt option , Such as QMutex, etc.

In addition, you have to consider whether the conversion is worth it or not. After all, Qt Windows will use Windows API in the background.

Let's say that you want to make your code cross-platform, you actually want to migrate directly with the use of Windows API, otherwise your code will be filled with preprocessor instructions at compile time.

c - Mpirun hangs when mpi send and recieve is put in a loop -

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...
