HELP NEEDED! export an excel table to a *.mdb database file using vba
does anyone can find a solution to my problem!
I have a mdb database called urunler_stok.mdb (U:\urunler-stok.mdb)
and an excel xls file (irsaliye.xls)
I use %95 the excel file and mdb file is only used to update product informations such as price, stock etc... When I open the excel file, it imports the table from the mdb file to sheet2. the imported table includes product id's, product names, unit prices and stock information.
on sheet1, i have a invoice template. when I enter the product name on sheet1, the product id and unit price automatically filled in the template.
what i am doing right now is, on sheet1 when an order is placed, the table in the sheet2 is updated and the order amount is subtracted from the stock colomn.
NOW, what i need is, i should export the updated table (which is on sheet2) to the mdb file back(which i have imported from at the beginning) with VBA.
After several errors, i finally solved all of this but now, it gives such an error message
"THERE WAS AN ERROR. UPDATE WAS NOT SUCCESFUL".
The original code is written by Ken Puls, but in that code, the records are being added to the table again. i do not want this and i want to re-write the updated table instead of the old one.
files are located in c:\. can anyone help? i can send the two files. many thanks for those of you who can help.
