program hangs using TDataModule

[hstijnen]

Hi,

Is there anybody using CBuilder XE with ZEOS compo's in a TDataModule?
On the moment I'm using such a datamodule, my program hangs when I start it.

When I do the following:
1. create new VCL application with default unit
2. add TDataModule
(run program: OK)
3. add ZEOS Connection to DataModule

Now run program ---> hangs

What can be on hand?

Thanks for help.

hstijnen,

Did you get an Exception?

Be sure the TDataModule was created BEFORE you create the Formular which contains TZConnection-Linked components.

I've tested it and it works except the creation order is wrong...

EgonHugeist,

A simple application is built, compiled and running in C++ 2007.
I get an error as attached after compiling and running it in the C++32 XE2 (at the start).
In the [s]runtime[/s] designtime is well.
R1941.

miab3,

wow zplainasa7..9 doesnt't exist any more! I've renamed this units to ZPlainASAConstants. Sure there are no deprecated files linked?

EgonHugeist,

It's okay.
I missed the path to the *. bpi.

I didn't create any line of code. My whole program consists only of two units, and one ZEOS connection compo, just created, without any modification. Here is the code:

Code: Select all

WINAPI _tWinMain%u28HINSTANCE, HINSTANCE, LPTSTR, int%u29
%u7b
	try
	%u7b
		Application->Initialize%u28%u29;
		Application->MainFormOnTaskBar = true;
		Application->CreateForm%u28__classid%u28TForm3%u29, &Form3%u29;
		Application->CreateForm%u28__classid%u28TDataModule4%u29, &DataModule4%u29;
		Application->Run%u28%u29;
	%u7d
	catch %u28Exception &exception%u29
	%u7b
		Application->ShowException%u28&exception%u29;
	%u7d
	catch %u28...%u29
	%u7b
		try
		%u7b
			throw Exception%u28""%u29;
		%u7d
		catch %u28Exception &exception%u29
		%u7b
			Application->ShowException%u28&exception%u29;
		%u7d
	%u7d
	return 0;
%u7d

When I start program with breakpoint at first try, I don't arrive there, I don't get any exception.
This is the event log:

Henk,

I was not able to reproduce this issue EXCEPT i have objects on my Mainform which are linked to the. TZConnection AND my Datamodule was created before the Mainform was created.

I'm sure if your turn around the creation-order(Datmodule before Mainform) the issue is gone.. Stupid question does the same happen to other components?

Hi all,

This problem occurs (on CBuilder 2010) when you have checked "build with runtime packages" option in your project (by default checked).

Since unchecking this option is one of first things i do when starting new project - i've never got such problems earlier:)

Best regards,
Marek
