File object not being cleared

Hi Guys,

I'm running into a problem that I'm scratching my head over. Any help would be appreciated.

I have a process running using the OnTimer trigger in version 4.0SP1. The problem is that the file variable does not get cleared and seems to "capture" the contents of a directory at a point when the client is being ran. So new files are not being processed and the loop is always looping through the files already processed.

The question is, how do I clear the file variable so it gets the current contents of that folder?

Here's the code:

Code: Select all

FileObject.RESET;
CLEAR(FileObject);
FileObject.SETFILTER(Path,'%1',TempPath);
FileObject.SETFILTER(Name,'ORDER-*');
FileObject.SETRANGE("Is a file",TRUE);
IF FileObject.FIND('-') THEN
  REPEAT
    TargetFilea := FileObject.Path + FileObject.Name;
    IF FILE.EXISTS(TargetFilea) THEN BEGIN
      <Runs a dataport pointing to TargetFilea>
      <Move the processed file into a separate folder>
    END;
  UNTIL FileObject.NEXT = 0;

this is a known bug and discussed many times on mibuso. You need to set another filter and then nav will look at the folder again.

Really? I searched and searched but couldn't find any thread on this.

When you said set another filter, can you elaborate? Do you mean change up the filter everytime the process is ran?

ara3n is right. I've seen quite a lot of posts about this before. basically you need to change the filter 'path' before you do FIND. This is needed to refresh the folder.

Code: Select all

FileObject.reset;
FileObject.SETFILTER(Path,'%1','c:\');
FileObject.SETRANGE("Is a file",TRUE);
IF FileObject.FIND('-') THEN;

FileObject.reset;
FileObject.SETFILTER(Path,'%1',TempPath);
FileObject.SETFILTER(Name,'ORDER-*');
FileObject.SETRANGE("Is a file",TRUE);
IF FileObject.FIND('-') THEN
.....
