Display All From One Table Even If It Does Not Exist In The Other
Nov 15, 2011
I have two DBF tables called product and ullage. The user enters data from products table into ullage, by searching for product id and adds their count into the ullage table. This part is working. how can I display the products table with all the prod_ID, Desc and price with Counts from the ullage table but were there is no count in the ullage table these product will be displayed but with no count number.
When I try to insert a value into table1 it will compare the table values if it is same, It Should throw a error msg "Name and Date Already Exist" otherwise Insert a value. Before Inserting i want to check a textbox value with table value.
I am converting a lot of projects from VB6 to VB.NET. Many of these projects use the DAO method CreateQueryDef, something ADO.NET does not. I know there is a way to replicate this method in ADOX using Catalogs, but I wanted to stay with pure ADO.NET. I have been using CREATE PROC to do this, but some of the query def's in the VB6 version mention tables/queries that are not created until later. For example,[code]The way the projects are, it is not possible to simply flip these two lines. I was wondering if there is a way to force CREATE PROC a AS SELECT FROM b even though b does not exist yet, or if there is a different option in ADO.NET to replicate the CreateQueryDef functionality.
I have a listbox populated from a column in a table. The data in the column contains some of the same data for etc. The word watch would be there 10 times but I only need it to show once.

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

I have a form which is primarily pulled from Table1. Table1.fieldA is an integer representing a project phase. In the current Access display the form displays not the integer, but a String stored in Table2 that holds integer/String pairs representing all the phases.I'm trying to figure out the best way to reproduce this in my .NET formview. I could write code that would parse the int and display text, then reverse the process at save or insert, however then the code has to be updated if a new phase is added to the database. draw the String values from Table2 while preserving the binding to Table1 but I haven't figured out how.
Was researching this but could only find how to use a datagrid which is displaying from a database?

I am new to VB.NET in Java it was just a matter of creating a table and a table model and loading the data through that way but not sure how to do it in .NET
