Dear All,

I have a doubt here:

If a set the error mode to 0 and then whant to create a msgbox if an certain script error happens how can i do it?

Code:

set errormode=0;

Load * from xx;

if ScriptError=8 then

Load

MsgBox('aa', 'aaa', 2, 48,512) as X

AutoGenerate 1;

//no file;

Does anyone know if thats valid?

Thanks,

Eliano

I haven't syntax checked your example, but yes, the concept is valid.

Hi,

you don't need a load statement to trigger the msgbox function. You can directly use it like this:

set errormode=0;

Load * from xx;

if ScriptError=8 then

let x = msgbox('file not found', 'caption');

end if

Another suggestion is to test if the file exists before loading it:

if isnull(FileSize('c:\folder\x.txt')) then

let x = msgbox('file not found', 'caption');

else

Load * from c:\folder\x.txt;

end if

Hi,

I want to ask you, is it possible to create a msgbox in your script with text: 'the missing field':

I mean that:

SET ErrorMode = 0;

Load * from XX;

If ScriptError = 11 then

let x = msgbox ('Field not found' , 'Name of the missing field')

End If ;
