I am new to foxpro and also wwsoap. I have the same problem the result is actually empty string cResponseXML = ''. So how do I know what is the actual error. I am converting a database row into xml cursortoxml and then sending it to soap server.
If I reduce the no of columns to 5 then I don't have a problem everything works fine. As I increase the columns, I get 'non xml result' . If I increase to 15 or 20 columns I get 'string too long' error. Any ideas?
Mark,

You can set the timeout on the Soap object and that timeout should be respected without a problem. If you're getting non-XML result returned that most likely means the server is returning an HTML error message... you can check what comes back with loSOAP.cResponseXml...

+++ Rick ---

We just began running the web service from a wireless client (a forklift). Occasionally, they temporarily lose connection to the network and the soap call times out after 15 seconds. Any future calls using the same oSoap object no longer work and timeout immediately, unless I re-create the oSoap object after the error (as shown below). However, the error message the user gets is "Non XML result returned". (cResponseXML = '' and cErrorMsg = "Non XML result returned"). Is there a better/more standard way to trap for connection timeouts?

Thanks,
Mark

Sample of code:

osoap = createobject("wwsoap")
osoap.lIncludeDataTypes = .t.
osoap.cServerUrl = "http://#.#.#.#/VwhService/VwhDataService.wwsoap"

osoap.addparameter("lcname","Test 1")
lresult=osoap.callmethod("helloworld")
If osoap.lError = .t.
mcErrMessage = oSoap.cResponseXML + CHR(13) + oSoap.cErrorMsg
=MessageBox(cErrMessage)
*
* To get the next oSoap.Callmethod to work, re-create the object. Without the
* following 3 lines, future calls to oSoap immediately fail.
osoap = createobject("wwsoap")
osoap.lIncludeDataTypes = .t.
osoap.cServerUrl = "http://#.#.#.#/VwhService/VwhDataService.wwsoap"
EndIf

osoap.addparameter("lcname","Test 2")
lresult=osoap.callmethod("helloworld")

I have been looking at this recently as well since it may need it for a pending client. I would use VoiceXML as it is a W3c standard and you can get a third party to host the voice part of your application. If you already have your business logic in WestWind, this should work for you.

The following example is from from http://www.voxeo.com/library/voicexml.jsp.

<?xml version="1.0"?>
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml">
<form>
<field name="drink">
<prompt>
Would you like coffee, tea, milk, or nothing
</prompt>
<grammar src="drink.grxml" type="application/srgs+xml"/>
</field>
<block>
<submit next="http://www.drink.example.com/drink2.asp"/>
</block>
</form>
</vxml>

A field is an input field. The user must provide a value for the field before proceeding to the next element in the form. A sample interaction is:

C (computer): Would you like coffee, tea, milk, or nothing?
H (human): Orange juice.
C: I did not understand what you said. (a platform-specific default message.)
C: Would you like coffee, tea, milk, or nothing?
H: Tea
C: (continues in document drink2.asp)

could not a 'help wanted' forum, thought this would do.

We are looking for a "voice self-service" system that is WestWind oriented. We have something cobbled together right now but it is too expensive for us to keep doing ourselves.
Our interest is either in a product already developed and for sale or for a developer who already has done one.

Aside from the basics, we need a setup that will understand the customer's voice and will do creditcard verifications through USBank's viaWarp.

We want people to call in, keypad or speak their account number and payment information. The system should then look up the customer's information to see that it matches and then verify the payment validity through viaWarp (which is a USBank application with a hook). So if there is another TLA for this, lmk :)

any leads appreciated.

For downloading huge files, I use the wwHTTP::httpGetEx() method

loHTTP= CREATEOBJECT("wwHTTP")
loHTTP.HTTPConnect(Domain)
loHttp.httpgetex(...)

I am trying to download files from yousendit automatically.
When I use httpget to download a file, it works fine until the file is greater than 16 megabytes. Then I get a "string too long" error from httpgetex.

How can I download long files from visual foxpro? For my current application I need to download up to 40 megabyte, but eventually I'd like to download up to the full 2 gigabyte limit.

I wrote a voice system back in VFP 5. The components of the system include a hardware voice processing card, software that interfaces to the card and an application that functions to fill your needs. The company I purchased the hardware from said it would work with VFP but had only tested it and not built a complete system with it -- they were pushing VB.

The company was called Parity Software who was bought out by Dialogic who was bought out by Intel. I still get the Newsletter from time to time but have not followed anything that is going on with that industry. It is a world all of it own.

The hardware comes in many forms - anywhere from two ports that connect into a standard telephone jack to a T1 Trunk and beyond. This stuff gets really pricey. The only good thing to say is once you develop your application to run with the hardware interface software, if the interface was well written, you should be able to switch between any product in their product line.

The VFP application was an answer machine that could route calls. This was before multi-line systems were available and most folks had endless tapes playing the announcement -- maybe early to mid 1990's, I forget. Some of the systems are still running but we no longer support them.

The biggest problem we ran into was compatibility between interface software and VFP on the programming end. On the hardware end, we found that not all telephone connections were the same. The hardware did not always work when hooked up to some providers - GTE Vs. Bell.

This is a huge project and should not be considered lightly.

Oh... I have no interest in doing another system at this time. I have a house to finish building first.

Good luck!

In the code you posted you don't show where you are calling on REPORT FORM but on the line that does that you need to add parameters that write it to a file or an NAME object.

Hi there,

I am new to programming and working on VFP 7. I have the following code that prints out the invoices once they are issued. I need to make some changes to it. Instead of printing the invoices, I just want them to save. I commented out the the statement that tries to print out the invoices once the button is clicked. The code is as given below.

*-- Change the status_id to issued

*-- start timing how long to issue an invoice
*!* MESSAGEBOX("Start Timing!")
*!* LOCAL timeTracker
*!* timeTracker = DATETIME()

glissuedbuttonflag = .t.

This.Parent.imgIssued.ZOrder(0)

*!* IF SEEK(thisform.oMasterObject.oObjectStore.invoice_no, "a_invoices", "INVOICE_NO")
SELECT ("a_invoices")
SET ORDER TO invoice_no IN a_invoices DESCENDING
LOCATE FOR ALLTRIM(invoice_no) == ALLTRIM(thisform.oMasterObject.oObjectStore.invoice_no)
SET ORDER TO invoice_no IN a_invoices ASCENDING
IF FOUND()

*****************
thisform.cntbmentrybuttons.cmdEdit.click
thisform.oMasterObject.oObjectStore.status_id = "002" &&- issued
thisform.cntbmentrybuttons.cmdSave.click
*****************
*!* SET REPROCESS TO 10 SECONDS
*!* IF FLOCK("a_invoices")
*!* replace a_invoices.status_id WITH "002"
&&- issued
*!* thisform.oMasterObject.oObjectStore.status_id = "002"
IF EMPTY(a_invoices.issuedate) OR ISNULL(a_invoices.issuedate)
replace a_invoices.issuedate WITH DATE()
thisform.oMasterObject.oObjectStore.issuedate = DATE()
ENDIF

*|* thisform.cntbmprintbuttons.cmdPrint.click
thisform.cntinvoicingdata.orderPages.page1.cntshippinginfo.cboStatus.refresh()
thisform.cntinvoicingdata.orderpages.page1.cntshippinginfo.cntdate1.refresh()
thisform.cntinvoicingdata.label1.caption = "ISSUED"
*!* UNLOCK IN a_invoices
*!* ELSE
*!* WAIT WINDOW 'Unable to open Invoices Table; try again later!' NOWAIT
*!* ENDIF
ELSE
g_alert("Invoice is not found!")
RETURN .f.
ENDIF

this.Enabled = .f.
glissuedbuttonflag = .f.

thisform.Refreshform()

*-- determines how long it takes to issue an invoice
*!* timeTracker = DATETIME() - timeTracker
*!* timeTracker = "Time:" + STR(timeTracker) + " seconds."
*!* MESSAGEBOX(timeTracker)

Therefore, I have to come up with a function that only saves the issued invoices instead of printing them. Also, it creates a table to insert records by using the following fields: invoice_id, invoice_no and status_id.

Your help is much appreciated.

Thanks alot,

I use McAfee VirusScan on my server. I have configured it to scan the folder I place uploaded files into. In my VFP code, I write out the uploaded file into the same directory. This causes McAfee to scan it since it is a new file. Then in a seperate action in VFP after checking to see if the file still exist, I move the clean file to its final folder.

That should do it.

BTW - I delete infected files and reply with a message that upload failed if the file is infected (not found).

Oh, if you are running in File Mode, you might want to Exclude checking the WC Temp folder - your performance is taking a real beating by McAfee.

I am sure someone else has come across this, but since I am somewhat new to WW development.. Is there a way to scan a file uploaded using WW Build 5.30 and McAfee so that I can isolated it prior to performing any other actions to the file and be able to inform the user that the file was infected?

Print the detail lines from a cursor instead of a table. Then you can add enough blank lines to fill out the entire page.

I have the need to print a basic 'purchase order' type form. The customer wants to emulate their existing paper form *exactly*, down to the fact that even if the purchase order only has 3 lines, then the form should print 3 lines of data and the remainder of the form as *blank* with the grid. Something like this

| Line # | Description | Qty |
-----------------------------------
| 1 | Line 1 | 3 |
-----------------------------------
| 2 | Line 2 | 2 |
-----------------------------------
| 3 | Line 3 | 1 |
-----------------------------------
| | | |
-----------------------------------
| | | |
-----------------------------------
| | | |
-----------------------------------
| | | |
-----------------------------------

So basically, the form always prints 6 grid lines - regardless of the number of actual lines of data. Using a REPORT FORM ..FOR.. , I just cant seem to get this to work. I can easily extend the column lines down by dragging them into the page footer and the stretch nicely.. but to get the additional row lines to print seems impossible. We would prefer not to have to really kluge to the point of inserting blank lines into the table.. we tried various calculations of # of lines to print and 'print whens' and 'dont print if blanks', but seems the vfp 9 report will always allow for *potential* max amount of space a group footer may require and it screws it up... Am I missing something easy? Any suggestions appreciated!

TIA,

Brian

Hi, all.
I´m trying to save an DBF file attached to an email with WWPOP3 and WWIPSTUFF classes and it runs but all that ASCII character out of range 32 - 128 are changed to string "=XX". For example ASCII character 3 (0x03) are translated into string "=03".
If i try to decode with VFP STRCONV function option 16 (Converts single-byte characters to decoded hexBinary) converts all the characters in the file, not only that ones that are in format "=XX" and the file results unreadable.

How must i decode the file?

Thank you all
