invalid blob and template

rbuser

I try to save a large report (means got many dbtext,label etc for the report
outline) to the database, but system pop out a message'Invalid BLOB' , so I
guess is the blob size problem, than I go to BDE administartion, database
set the BLOB size to 1024, after I set the BLOB size, I was able to save the
report, and it was no problem for me to preview and design.after this, I try
to close the report, exit the whole program, than start again, when i try to
preview the report in second time (after log out the system and log in
again ), it pop out an error message ' Invalid template format' . so may I
know what is the problem ?

Thanks for reply !
I not sure how to adjust MaxBlobSize property of my dataset, can you tell me
more detail about how to find out this property?
I try to change the database type to binary, report pop out the message
after I exit and enter again 'exception class EParseError Line too long on
line 1237'. is it because the same problem?
May I know normally what data type is suitable for store report format,
'text? varchar'?
I am using sysbase with report builder Pro 7.03 for delphi 5.
Thanks.

Hello,

You may still need to adjust the MaxBlobSize property of your datasets. I
believe if you set this property to -1, there is no maximum set. If this
does not help, feel free to send me the template in question and I will try
to load it on my machine.

Hi,

MaxBlobSize is a property of TCustomSQLDataSet. You should be able to
access it from your TDataSet. I'm a little unclear about what your
application is trying to do when you receive the error. Perhaps an
explaination of what your app is supposed to accomplish would help me
understand the issue.
