C++ Builder IDE, Always overwrite

2. overwrite dialog for streamwriter?

Hello,
I am using StreamWriter, and I want to check if the file I intend to
write to already exists and to have the choice to continue or bail
out.  I know that File.Exists(name)  will check whether the file
already exists.  But I can't spot a built-in way to generate a dialog
for the user to continue and begin writing or to quit.  I guess I
might write a specific dialog box for this....?  Thanks for
suggestions.

4. Overwriting image metadata

I need to read the metadata of an image, display it on the screen and allow 
the user to change it and then re-write the metadata back into the image. 
The issue I am having is if I try to rename or delete the existing image 
before re-writing the image file I get an error stating that the image is in 
use.  I am using Image.FromFile() to read the file.  I have tried disposing 
of the image and running the garbage collector (GC.Collect()), but it still 
doesn't work.  Is there a way to actually close the file so I can 
delete/rename it?

Thanks,

Tim

6. overwrite a class in memory?

I have a fat class. I have lots of other classes that reference it. I
want to make a new fat class without requiring everyone to update
their references to it. Am I crazy? Any idea on how to pull this off?

8. RichTextBox code to change the Insert/Overwrite mode does not work

I have a RichTextBox and I want to programmatically change the 
Insert/Overwrite mode.

I tried the following but it doesn't appear to change the mode.

Pressing the Insert or Ins key does change the mode.



Any suggestions or verification?

Thanks
