@RBertora: I've looked at the proposed website, but my form is pretty complex, with lots of controls, creating it this way would be a pain.<br>Is there maybe a way to convert the current form into the setup as proposed? Or is there another way?

Ok just a suggestion , not sure if it will help as there are many reasons why your save might not be working / crashing that may have nothing to do with the form creation, but as you feel its in creation, then just try this, not sure if it will help<br />
<br />
procedure TFMain.OpenMyForm(CONST ID : String; vMakeCopy : Boolean);<br />
var MyForm : TForm;<br />
begin<br />
&nbsp; &nbsp; MySettings := ID;<br />
&nbsp; &nbsp; MyForm := TFMyActualForm.Create(Appl<wbr />ication);<br />
&nbsp; &nbsp; MyForm.Show;<br />
&nbsp; end;<br />
end;<br />
<br />
I see you create a Form variable in the procedure, so the procedure is the owner of the form variable, even though its somehow hooked up to Applciation.<br />
<br />
I think taking the var MyForm : TForm; out of this procedure might just sort this mess out, there is no real logical basis on this comment just a hunch.<br />
<br />
Instead passing a global instance of a form variable into this procedure through the params. &nbsp;I would maintain a global &nbsp;list of form variables and add / remove from that list as you open and close forms..<br />
<br />
just a hunch, again, the issue might be nothing to do with form creation... but hey
</div>


<div>
MySettings are multiple vars that at form's creation are store in the form's own private vars.<pre><code class="code-1 nolinks" id="code-20-43073829-1"><span>FMySettings1 := MySettings1;</span>
<span>FMySettings2 := MySettings2;</span>
</code></pre>If I understand correctly you suggest to create the forms like this?<pre><code class="code-1 nolinks" id="code-20-43073829-2"><span>procedure TFMain.OpenMyForm(CONST ID : String; vMakeCopy : Boolean);</span>
<span>begin</span>
<span>&nbsp; MySettings1 := ID;</span>
<span>&nbsp; MySettings2 := 'My var string';</span>
<span>&nbsp; FMyActualForm := TFMyActualForm.Create(Application);</span>
<span>&nbsp; FMyActualForm.Show;</span>
<span>end;</span>
</code></pre><br>

Sorry, but I don't understand what you mean by that?<br>The form needs to be created because it's freed in the OnClose-event. Otherwise there would be lot's of forms 'floating' around.<br>Can you give an simple example to clearify?
</div>


<div>
Sorry I do not have Delphi since 15 years ago. What I am saying is find out where in Delphi you can create and manage global variables, a global variable can be of any type, and should be accessible from anywhere in the code, anywhere...<br />
Then yes I am suggesting you manage the form variables globally, in a list(easier), or array(harder), the onclose event can access the global form instance and dispose it because it is in a global area of memory.<br />
<br />
More than that I cannot help you, yes I am suggesting handling the form management yourself in global code.<br />
<br />
1 - I do not know it will solve your problem<br />
2 - I think its too much for your current programming skills if I have to spell this out to you any further<br />
<br />
This unfortunately is my final comment in this thread, as I will not be able to help you with any example as I do not have Delphi.<br />
<br />
thanks<br />
Robert.

Hi,<br />
<br />
In my application I need to start several instances of the same form, each one with unique settings. <br />
Multiple instances might be opened for a while. The main application must remain available to work in.<br />
Sometimes when I push f.e. the save-button on one of these forms the application freezes and in the Delphi IDE I see &quot;Main thread stopped : 1492&quot; in the titlebar. After that the only way to recover from this is to shutdown Delphi via taskmanager and restart).<br />

<pre><code class="code-1 nolinks" id="code-10-29179665-1"><span>procedure TFMain.OpenMyForm(CONST ID : String; vMakeCopy : Boolean);</span>
<span>var MyForm : TForm;</span>
<span>begin</span>
<span>    MySettings := ID;</span>
<span>    MyForm := TFMyActualForm.Create(Application);</span>
<span>    MyForm.Show;</span>
<span>  end;</span>
<span>end;</span>

Does anyone have any idea what might be a possible cause? Or maybe there is a better way to create instances of the for?

Hi,

In my application I need to start several instances of the same form, each one with unique settings. 
Multiple instances might be opened for a while. The main application must remain available to work in.
Sometimes when I push f.e. the save-button on one of these forms the application freezes and in the Delphi IDE I see "Main thread stopped : 1492" in the titlebar. After that the only way to recover from this is to shutdown Delphi via taskmanager and restart).

Does anyone have any idea what might be a possible cause? Or maybe there is a better way to create instances of the for?
