Controlling the ''Executing remote" message when using SQLEXEC()
I've got a routine that imports data from a Paradox file using an ODBC connection via the SQLEXEC() function.
When this executes, I get a message in the top-right of the program window saying
Executing remote... Pres ESC to cancel
Is there any way of controlling the placement of this message - can I display it in one of my own error messages for instance? Is there any way of suppressing it perhaps?

It was a mistake. The record counter is displayed in FoxPro status bar when the data set is large or when the data transfer is slow.
If you define your own message window then you have to handle record counter and/or thermometer in your program which is complex, not reliable, and slows the whole process down.
We are using following progress window when copying data over the slow network:

Alas.
Take your point about slowing things down, but I do like to give users some idea of what's going on.
What I've done is to use the status bar record counter. I need to tell the user about how many records are being imported. I've done that with a little function which uses low-level file functions to read the record count from the top of the Paradox file, as in
* PARADOX_RECCOUNT() - Return number of records in a Paradox .DB file
* VARIABLES
LPARAMETERS tfParadox
LOCAL lhParadox, lnRecords
* tfPARADOX - Name of Paradox file
lhParadox = FOPEN(tfParadox) && Open file
IF ( lhParadox < 0 )
RETURN -1
ENDIF
FSEEK(lhParadox,6,0) && Bytes 6-9 contain record-count
lnRecords = CTOBIN( FREAD(lhParadox,4), "RS" ) && Convert binary string to numeric : "R" = little-endian, "S" = unsigned.
FCLOSE(lhParadox) && Close file
RETURN lnRecords
I've then displayed this in a window so that the user can see the (eventual) record-count.

Sorry - the code in the previous comment should be presented tidily as
* PARADOX_RECCOUNT() - Return number of records in a Paradox .DB file
LPARAMETERS tfParadox
LOCAL lhParadox, lnRecords
* tfPARADOX - Name of Paradox file
lhParadox = FOPEN(tfParadox) && Open file
IF ( lhParadox < 0 )
RETURN -1
ENDIF
FSEEK(lhParadox,6,0) && Bytes 6-9 contain record-count
lnRecords = CTOBIN( FREAD(lhParadox,4), "RS" ) && Convert binary string to numeric : "R" = little-endian, "S" = unsigned.
FCLOSE(lhParadox) && Close file
RETURN lnRecords

I've now got one of my own messages displaying what's happening.
Your comment says "Of course, the original message can display the data transfer progress which is impossible in this case". Do you mean that it is possible to get the default message to display a progress thermometer or a count of some sort?
