WORKBOOKS.OPEN (URL) - How to trap a connection-lost/ timeout erro
Set wbkMyWorkbook = Workbooks.Open(URL) Using this statement, I try to open a .csv file on a remote (securities exchange) website. How might I trap the error(s) of: network connection timeout, Excel process not responding, HTTP file not found. My macro was working great until yesterday, but today it eats up CPU resources - process-not-responding. I am able to debug, independently retrieve the URL string & download the CSV file by pasting the (debug) URL string on the browser window. I am on Excel XP & a 64kbps connection to the Internet. Any ideas why the macro dies? TIA!!

Maybe you can try this
You can check your connection before you run your code See the website from Randy Birch http://vbnet.mvps.org -- Regards Ron de Bruin http://www.rondebruin.nl "BHARATH RAJAMANI" wrote in message ...

WORKBOOKS.OPEN (URL) - How to trap a connection-lost/ timeout
Thx so much Ron!!, I tried the following:
a. (Debug) Watch URL: http://www.nseindia.com/content/hist...AY2003bhav.csv Copied this URL to Internet Explorer - it works fine b. Wrote a new sub with a simple Workbooks.Open ("http://www.nseindia.com/content/historical/DERIVATIVES/2003/MAY/fo26MAY2003bhav.csv") statement .. which does not execute either. My bandwidth is okay and the file opens via IE. Is there anyway to specify wait time etc in VBA, I dont want to end-task MS Excel each time, on a simple Workbooks.Open statement!! I need to retrieve the market data from a remote location, so there's no business alternative for me. Either the exchange website or a Bloomberg/ Reuters machine on the network. Is the Workbooks.Open (URL) function RELIABLE to retrieve remote flat-files (loop 60 to 90 CSV files of 5000 rows each)? Would I be better off using an API .. Can I use the URLDownloadToFile API from vbnet.mvps.org? The usual tricks .. restart reboot etc did not help either. I need a way for my macro to exit if it does not receive a response from a remote computer for a file request. Any thoughts? TIA !!
