Updating SQL server table with vb.net 2010 datagridview -


I have trouble updating my database table with datababridge, I have read some thread about the problem and some Not even my case. Here the code I use is DataGridView populated. public DATE filldatagridserver (as byRef SQL string, byRef DG as DataGridView) MyDataset Dataset = new dataset myAdptr.SelectCommand = new SqlCommand (sql, cnSQL) myAdptr Fill (myDataset) dg.DataSource = myDataset.Tables (0) dg.AutoResizeColumns () myAdptr.Dispose () myDataset.Dispose () cnSQL.Close () End Sub

This sub process with code says: 

  call filldatagridserver ("select * from tblQuarterCollection", dg quarter)   
 I used already MyAdptr .update but I  
 table While getting an error about mapping, I tried to settle and also said that in the sub process, to try to quote a lot out but it still does not work. Anyway, fill the DataGridView properly and update the changes made in the database. I think that here my last resort will be looping through each record, data will be updated in the data grid view according to current data. Please help   
 
 
 try this:.  
  Private sub-btnAdd_Click (as the object, in the form of e EventArgs) handle btnAdd.Click add new as SqlCommand addcmd ("(insert in tableName value @ col1, @ col2) ", YourConnectionString) addcmd.parameters.addwithvalue (" @ col1 ", txtCol1.text) addcmd. Parameters.addwithvalue ("@ col2", txtCol2.text) addcmd.executiononQuery closing sub

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.
