I am attempting to pick apart a DBF file using the code in THIS AskTom post however I have no clue where I would even go to figure out how the files I'm wanting to pick apart are formatted? How was the original AskTom answer even produced? How do I figure out the dbf Header. How do I know where within the dbf file the data is stored or even how to pull out that data? My goal is to work with the code provided and come up with a solution as others have done but I'm stuck at the very first part. While researching this I found that there are many systems that use DBF files. ACCESS and MS Excel

问题 I am trying to pull data from DBF files into my program using C#. I am using the Visual FoxPro OLE DB Provider.

I'm having a problem opening a DBF file - I need to open it, read everything and process it. I tried several solutions (ODBC/OLEDB), several connection string, but nothing worked so far. The problem is, when I execute the SQL command to get everything from the file, nothing gets returned - no rows. What's even more odd, the content of the DBF file being opened get deleted. See the code I have: public override bool OpenFile(string fileName, string subFileName = "") { OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetDirectoryName(fileName) + "

Is there any free tool to convert a file with more than 65000 registers from DBF format to CSV?

问题 I need to convert a very large file from DBF format to CSV format. I have tried Microsoft Excel to do the job, but the problem is that I cannot see more than 65500 registers when I open and export the file. Microsoft Access couldn't open the file, too. I have found on google some shareware tools, searching for "DBF to CSV". Have you tried any of these with very large files? Also, any solution that could export to mysql or postgresql database formats will be welcome. Thanks in advance for your

Alright, I'm using an ancient database format here, dbf files. Don't ask why, just know a certain software decided to extend foxpro support because microsoft decided to extend foxpro support. Now, I'm getting the following error on a specific file. I have successfully loaded another file and I'm curious if there is something wrong with this database. I'm sure you probably need to look at the database to determine that, but its way to huge to post so I'll take what I can get. Traceback (most recent call last): File "billsapi.py", line 250, in <module> x.getUsedGuns() File "billsapi.py", line 72
