Question

Need to delete and import data into DBF file

Asked by: nemesis1210

Very early into this project (installing Visual Studio as I type this) and am looking to get some guidelines on how to go about completing

I have a CSV file with data which I need to import into a DBF file, I want to do this with a windows interface so the user can click on one of two buttons which will look for the CSV file in a specific location with a specific name and then depending on the button clicked delete records within a DBF file that have a specific value in a field and then import the data from the CSV into the DBF applying that value back into the field essentially replacing all data in the DBF for those records with that value, the other button works the same using a different value.

I am new to this and looking for an idea of which language is best to use to accomplish and the general guidelines to follow. I do have some experience with C# and VB not much however, I also have some SQL experience however have never worked with foxpro tables.

Thanks for your time

I'd do it in FoxPro or Python. User interfaces are easy and so is adding records to a table from a CSV file.

Perhaps someone with with C# or VB expertise will say otherwise.

Do you have FoxPro or can you get it?

Python is open source therefore free.

ok so I am using VB.Net for the moment I can see the table in the Data Connections section of the Server Explorer, but what to do I need to do to have the button on my form delete certain records from that table?

Did you look at the links CarlWarner provided?

 

by: nemesis1210Posted on 2008-10-24 at 08:43:47ID: 22797459

Yes I did which has helped me to see the table in the Data Connections section I have also created a Dataset and can see the field names from that, but for the moment I have a form with a button that does nothing I want to know how to have that button perform the funtions on the data

Do you know how to write event procedures in VB?

You will have to write one for the command button click event. In that procedure you will create the appropriate file reading and SQL statements to accomplish your task.

Unfortunately I do not have Visual Studio installed. My knowledge of these things is derived from MS Access (Visual Basic for applications).

Perhaps someone else will have the knowledge to flesh this out for you.

Are you still open to other language choices?

 

by: nemesis1210Posted on 2008-10-24 at 09:52:23ID: 22798088

I dont know the code to use in VB.net I too have done similar things with access databases using VBA but that was years ago, I am still open to any of the languages available in Visual Studio 2008

 

by: ramromPosted on 2008-10-24 at 14:33:54ID: 22800302

Then I can't help. If you decide to go outside the VS box let me know.

 

by: Olaf_DoschkePosted on 2008-10-24 at 14:45:57ID: 22800392

Well, if you have a VFP table in a .NET dataset, question to work on that dataset are purely .NET related, as the data arrived in the .NET world. So you better ask in that section how to delete a record in a dataset.

Bye, Olaf.

Sorry, you ARE already posting here. It's me who's in the "wrong" section.

"ok so I am using VB.Net for the moment"
"I dont know the code to use in VB.net "

It sounds like this is a question for another forum - specifically a VB.net forum where you can find an audience better suited to answer your VB.net questions.

Once you understand the necessary basic syntax in the language of choice (regardless of the back-end table you are using), then for specific VFP questions, we are here to help.

Good Luck
