c# - calculations in dynamically generated controls in windows form applications -


I am creating a program to learn how to generate dynamically control inside the loop at the Button_Click event , Now I'm trying to multiply two fields and their output in the third text box

code: 

 for  (int i = 0; i & lt; Ds.Tables [0] .Rows.Count; i ++) {Unit.Location = New System. Drawing Point (Unit Startup, Unit Startup V); Unit. Size = new system Drawing. Size (100, 30); Unit. Text = ""; Unit. Name = "Unit" + Eye. Toasting (); rate. Location = new system Drawing. Points (Rastestat position, Rastestat position V); Unit. Size = new system Drawing. Size (100, 30); rate. Text = ""; rate. Name = "rate" + i.ToString (); Amt.Location = New system. Drawing.Point (AMT Startup, AMTTartPision V); Amt.Size = New System Dropping Size (100, 30); Amt.Text = ""; Amt.Name = "amt" + i.ToString (); Panel1.Controls.Add (unit); Panel1.Controls.Add (rate); Panel1.Controls.Add (AMT); UnitstartpositionV + = 30; RatestartpositionV + = 30; AmtstartpositionV + = 30; Unit = new text box (); Rate = new text box (); AMT = new text box (); }   
 Now I want to calculate it like  
  amt0.Text = (ConvertToInt32 (unit0.Text) * * ConvertToInt32 (rate0.Text) ). ToString (); Amt1.Text = (ConvertToInt32 (unit1.Text) * ConvertToInt32 (rate 1. text)). ToString ();   
 and so on  
 In the end, I want to add all amt (i). Please help get it.   
 
 
 start from the line 'unitstartpositionV + = 30;' Next, I came here to solve it:  
  unitstartpositionV + = 30; RatestartpositionV + = 30; AmtstartpositionV + = 30; Unit = new text box (); Rate = new text box (); AMT = new text box (); Unit.Tag = Rate; rate. Tag = emt; Amt.Tag = Unit; Rate.TextChanged + = rate_TextChanged; Unit.TextChanged + = unit_TextChanged; }} Private Zero Rate Tag (object sender, EventArgs e) {var rate = Sender as text box; Var amt = rate.Tag as text box; Var unit = AMT Tag as text box; Calc (rate text, unit. Text, AMT); } Private Zero UnitTabut Change (Object Sender, EventAgds E) {var unit = Text box as sender; Var rate = unit.Tag as text box; Var amt = rate.Tag as text box; Calc (rate text, unit. Text, AMT); } Private Zero Calc (string rate, string unit, text box AMT) {int rateInt; If return (Int.TryParse (rate, rate rate)); Int unitInt; If return (Int.TryParse (unit, out unit unit)); Amt.Text = (rate IIMIT unit). Ostring (); }

 I have solved this problem in an unusual way, the style you are fit with, Ve showed But in fact you should use arrays, or lists, or any kind of 'collection' to keep your control. By reviewing your other answers, I do not think that you have yet learned about IEnumerable, this is the concept that Which you are missing thus Mr. activity will make it very simple (especially "All You Need").

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...
