Re: (Novice) parameter question

Carl,

Your script is a little difficult to follow. I think the most important thing would be to learn how to debug your programs, which will help you solve any problems you encounter. The FoxWeb documentation lists a number of debugging techniques, which are applicable in different situations.

For example, it would probably be helpful to you if you added the following statement right after you read the values of mode and refno:

Response.Write('lmode=[' + M.lmode + ']<br>')

Response.Write('gRefNo=[' + M.gRefNo + ']<br>')

Response.Flush

Alternatively, you can display these values in your channel window, using the ? command.

Another useful technique is tracing through your programs, as described in the Troubleshooting chapter of the FoxWeb documentation. The procedure is fairly simple:

Disable the Hide Windows option.
Enable the Keep PRG files option, which will allow you to trace through the PRG file that is generated from your fwx file.
Add the command "SET STEP ON" at the desired place in your script.

As soon as execution hits the above statement, VFP will open the trace window and allow you to step through your code.

Regarding your question about passing parameters between procedures, the fwx file is converted to a regular VFP PRG file and from there to an FXP file. All native methods work, including the use of private variables that are visible to procedures you call down the code (not recommended) and passing parameters (recommended).

I've got a program that has 3 procedures a main procedure, a display and a save procedure. I can't seem to figure out how to pass the value (reference number) selected from my main procedure into the other 2 procedures.

here's my program:

m.lmode =PROPER(Request.item("mode"))
m.lgRefno = (Request.item("refno")) //this is empty

DO CASE
CASE m.lMode = "Mainform"
DO MainForm

CASE m.lMode = "Savedata"
DO SaveData with m.lgrefno
CASE m.lMode = "Survey"
DO pSurvey WITH m.lgRefno
ENDCASE

PROCEDURE Mainform
%>

</HEAD>
<script>
function submitVal(varin) {
if (varin=="Survey") {
document.survey.mode.value = varin
document.survey.submit()
}
}
</SCRIPT>

RefNo,;
bd_Name,;
