Out of Memory writing to file.

rbuser

Using RB6.03, D5, W2K.

I am writing a report to generate a fixed length text only output file. I am
processing the report with 2000 records and all works fine. When I run
15,000 records, the report blows an out of memory error. I have turned
CachePages off. All output is to a file, not to screen or printer.

Is there something I am doing wrong or is there a fix for this?

Thanks,

Andy

First, run your project through a memory resource analyzer to search for
memory leaks. Otherwise, you are running up against the limitations of your
machine. After CachePages is turned off, there isn't much else to reduce the
memory usage to create the report in RB.

Try setting the Report.CacheManager.CacheType to ppCTFile at runtime.

TppCacheManager.CachePath

Run-time only. You should rarely, if ever, need to set this property.
When
a report is very long (over 1,000 pages), the report engine may switch
to
disk-based caching if it runs out of memory. In the event that this
occurs,
the value of this property indicates the directory to which the
temporary
caching files will be written.

Defaults to the current windows path for temporary files.

TppCacheManager.CacheType

Run-time only. You should rarely, if ever, need to set this property.
When
a report is very long (over 1,000 pages), the report engine may switch
to
disk-based caching if it runs out of memory. In the event that this
occurs,
the value of this property indicates whether the caching has changed.
Also,
if for some reason you would like to force file caching, you can set
this
property to ppCTFile. The temporary caching files will be written to
the
directory specified in the CachePath property.



Value Meaning
----------------------------
ppCTFile Report engine caches to disk files.
ppCTMemory Report engine caches to memory
