now i used another way:
the application starts with a main-function, not with a form. inside this i load and show the forms.
[tt]
mdiform.show
form.show vbmodal, mdiform
[/tt]
the background is that an mdichild can not be modal which is important in this case. the application handles some different things and at startup you should decide what to do. you know this behavior from the vb - programming - environment. it's an mdi-form and on startup you see a dialog form.
