dynamic TImage component creation

I tried to create a TImage component by using this source code:



// ---

TImage *Image = new TImage (Application);

Image->Picture->LoadFromFile ("a.bmp");

// ---



There are no errors, but the image does not apear on the form. I also
tried setting properties, like: Left, Top, Height, Width, Visible, but
that didn't change anything.



Maybe I'm doing something wrong or I'm forgeting to do something. I
would be thankful for helping me out.

Some will flame you for being OT, but most importantly
your chances of getting a helpful answer are much slimmer
than on a dedicated NG ( i.e. borland...., see their web site).

You probably need to create the Image within a specific Form,
not as a child of the Application object...

Not sure about TImeage but most VCL visual stuff requires an owner and a
parent.
Also, LoadFromFile() probably throws on failure so you would need a
try/catch to handle
errors.

TImage *Image = new TImage (Application);
Image->Parent = this; // or wherever you want the bitmap
try{
Image->Picture->LoadFromFile ("a.bmp")
} catch(Exception &spoo) {
//whatever on failure
}

This is the wrong place for this question though. Try
