View 9 RepliesI am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.
View 5 RepliesI am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks.

View 2 RepliesI want to exit a recursive function once the a number is repeated in a list. i.e. In the following code I have 'AST' as a list. How can I stop adding data to the list once the first number repeated?

I have a design question about parsing data in Silverlight. I need to allow my users to validate their csv data (they paste ten rows into a textblock), but I am not sure if I should attempt to do it on the client side where I don't have access to the textfileparser class or send the data to a webservice for validation. If I send it to a webservice how do I ensure the data is secure?

The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:

Please take a look at the code below. I was told by the individual that developed itoriginally that the code only adds the rows of data the user entered. In other words,there 5 rows of textboxes. user can enter data into one row or into all 5 rows. If the user enters data into one row of textbox, that's what gets inserted into the db.I made some minor change to the code so that users can tell when a payment is made by check or cash payment.Since I made that change, whether a user enters data into one row or all 5 rows, all 5 rows get inserted into the db.How can I modify this code to ensure only rows entered get inserted?
