Hi,

I am doing a DLL that is called by a C DLL.

The DLL open some forms and crash when form close.

I did exact same thing in VCL mode, no crash.

Any hint about things to take care using KOL for making DLL that display forms ?

Unfortunately I can"t because this problem was 3 months ago and I decided to switch the project to VCL (I didn"t knew about this forun at his time).

Thank you.

Загрузка dll динамическая?
Попробуйте объявить в dll переменную hApplet: PControl и дальше в dll работать с ней. Тое есть создание формы и т.п.
hApplet := NewApplet( "fake applet" );
NewKOLForm1( KOLForm1, hApplet );
и так далее. У меня это ситуацию спасло.

Excuse me Falcon, but I don"t even read a word in russian.

I just read that you say something about applet. I already added applet to the DLL form because if not, the ShowModal I use do not "stop" on it and continue to process the code.

I"ve tried this method on a dinamick dll loading
Try to define in the dll hApplet as PControl variable, and use it with creating form e.t.c.

hApplet := NewApplet( "fake applet" );
NewKOLForm1( KOLForm1, hApplet );

Applet is a global variable, and if you are using Free_And_Nil( Applet ) in a dll code, it might
cause a crash.
