Hi folks!
I have a strange problem with the C++Builder 6 IDE. I have developed a
wizard (PaletteBar) which is distributed as a BPL-file. The wizard is
written in D6/7 and runs there without any problem. Normally I can load a
D6 BPL in to CB6 and use it there (PaletteBar before Version 3.00 did so).
The new version 3.00 of PaletteBar (including Docking support and others)
comes now up with an error in the CB6 IDE (translation from the german error
text):
Registerprocedure pb_main.Register in package <youknowwhat>has caused a
EReadError: Error reading ImageList->Bitmap. ImageList data could not read
from stream.
This happens when I call the Create function of the main form:
procedure Register;
begin
// Stuff for docking
RegisterFieldAddress (cWizardName, @FPaletteBar);
RegisterDesktopFormClass (TPaletteBarForm, cWizardName, cWizardName);
// create the main form
FPaletteBar:= TPaletteBarForm.Create (Application);
end;
The OnCreate Event is never fired, the error above is happend before.
When I delete the bitmaps in the ImageList, the wizad is loaded by CB6
without any problem, and all functions are working well. The same BPL
loaded with D6 runs also without any problem.
Has anybody a hint for me whats going on, and how can I solve this?

and saved using an IDE being run in Windows XP themed mode. However, I
would have thought that the Delphi6 IDE would {*word*88} the same as BCB6 did.

Hi All,
I use the clientdataset(cdsQuery) to call the datasetprovider(dspquery)
to update the fields. There is no problem using interbase 6.5, but SQL200. I
use try....except, there is no problem exceptional error prompt. but the
errorcount is 1 when i use the following command.
database1.connected := true;
database1.StartTransaction;
try
dspQuery.ApplyUpdates(Submit,0,ErrorCount);
database1.Commit;
except
on E:Exception do
begin
SHOWMESSAGE(E.MESSAGE);
Result := e.message;
database1.rollback;
end;
end;
I wish to know what is the reason and how to know that error where the
errorcount is 1.
PS the table structure is same in interbase and sql2000.
Thank all,
 

Hi there,
Iam using D6.
After creating a form I perform the following actions
1) edit1.clear;
2) edit3.clear;
3) edit4.clear;
4) edit5.clear;
5) edit6.clear;
6) edit8.clear;
7) edit9.clear;
8) memo1.clear;
for some strange reason I get a (consequent) error on line 7, 'edit9.clear'.
The strange thing is that when remove line 7 then I get the same error on
line 6, etc etc, When inserting a new line 8 containing 'edit10.text' I get
the error on that line .............
I only get this error on one specific form. There rest of my form's are
fine.
The precise error is : Project 2004.exe raised exeption class
Eaccesviolation with message 'accesviolation at adres.........
Is there something that I miss or what !?!
Kind regards Erik

forum, then it would help a lot to diagnose your problem.

And by the way, this is not the best group for posting

Hi,
I am using Delphi 6 Enterprise (with the latest updates).
I am connected via a TADOTable to an access database table.
My table has approx. 150 records in it, with an autoincrementing
id-field, called ArchiveID as the primary key.
When I execute the following code:
if tblArchive.Active = false then
tblArchive.Open;
tblArchive.Last;
showmessage(tblArchive.fieldbyname('ArchiveID').asstring);
Now instead of getting a message showing '150' I am getting a message showing '94'. I checked in my table and I have sequencial records from 1 to 150.
Why when I call the last procedure does it not position itself on the last record in the table, in my case the record with an ArchiveID=150??
Many thanks for you help

ORDER BY clause on a SELECT. You are positioning to the last physical
record in the table. That has nothing to do with key order.

You are positioning to the last physical
 

Could it be anything else??
Cheers,

the whole point. You were simply displaying the table
in it's "raw" order.
The Access GUI may display the table in what you
perceive to be the "correct" order, but that doesn't
mean it's actually stored that way, or that an ADO
recordset will show the data in the same order.
Outside of MS, no-one really knows the structure of an
MDB, but it's likely that a new record may be placed
not at the "end" of the table, but placed in a position
where a previous record was deleted.
Like I said, use an ORDER BY clause.

Hi
I have an application, D7, BDE and Paradox, install on a local network.
The network include one main computer with the application and the data,
and 3 other station.
I check and double check that all the BDE setting are ok (the path, the net
dir
and the local share) all are directed to the main computer. The application
too
is installed only on the main computer and all the others have only
shortcuts.
Now to the problem: the application run fine on the main computer and on
2 station. Only one computer raise, on some modules, error messages like,
index out of date or index doesn't exist, and on others modules is ok.
There is only one Alias for all the application.
I don't think it should matter but the problematic computer work on WinXP,
and all the others with Win98.
Any suggestion will be appreciated
Thanks Sorin
 

I have a problem that is annoying at work and a killer at home.
at work:
I have dual head using onboard i845 APC for left monitor and PCI ATI
Xpert 128 for the right.
In the IDE I have a problem of dialog boxes not having the text if they
display on the left monitor but I can drag them to the right and see
what they say. (Like I said "annoying")
at home:
I have a dual head using an AGP ATI Radeon & PCI ATI 7000
I get NO text anywhere in the ide.

Do you see where I am going with this?
Has anyone ever seen this before?
TIA
