Hi, if anyone can help on this, please! This is driving me crazy.
I have a user control hierarchy several levels deep that derive for
UserControl (windows).
The class that is at the top level, has the following constructor (generated
by VS.NET)
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeCompo nent()
'Add any initialization after the InitializeCompo nent() call
End Sub
Sometimes (about half the time), when I recompile my solution (which
contains a project with this class, and a project with a form tester trying
out this user control), I get the error I put in the subject of this post.
Now, clearly, this class has a constructor.
If I change the code by removing the word 'Public', and recompile everything
is great.
Next time I need to recompile, I get this error again. In this case, I just
put the word 'Public' back in, and recompile - all is well again.
So I spend half my time removing 'Public' and then adding it back in - just
to get the compiler to change its mind.
Now, it doesn't do this all the time. Sometimes it recompiles OK.
I've checked the project build order - and the project with the user control
is compiled first.
I've tried manually compiling the first project - and then the second. And
the second always fails, because it thinks there is no constructor available
for the user control. Until that is, I take away or remove the 'Public'
keyword off of the constructor - in which case its fine.
Is this some ridiculous VB compiler problem? Some VS.NET bug. Anything I can
do about it?
Thanks

As you can see in my response to Jay, rebuilding the solution helps. I am
still mystified as to why this happens at all, and why this particular error
in this particular case.
In any case, thanks for taking an interest and trying to help.

I can not reproduce it, can you tell me what I have to add to the method?
After you answered the question from Jay of course.
However you will see my next answer not for tomorrow probably, so do not count to much on that.

This is VS.NET 2003.
I am referencing the generated DLL.
Oddly enough - chosing rebuild solution does work.
I've gotten used to doing just a build (ctl + shift + b), and I've doing
that for probably 3 years and haven't had a problem yet. I guess I'll have
to reassign that to the rebuild command...
Do you have any idea why rebuilding the solution helps?
Or better yet, why does this happen at all?

are in one project, Form1.vb is in a separate project (one solution).
The key is, there has to be a change in the controls dll (such as adding
a Protected method to BaseInputContro l.vb), that will trigger this. Not
all changes cause this behavior - so it doesn't happen with every change -

Wierd question, but how many projects are in your solution... I ran

"Marina" <so*****@nospam .com> schrieb Well, just try adding a new method to BaseInputContro l that is protected - doing that usually does the trick for me.
When I do it, I get an error in BaseInputContro l:
"TestControlLib rary.BaseInputC ontrol.Private Sub InitializeCompo nent()" is
not accesible in this context because it is "private".
I think the error is not ok. When I rebuild, the error disappears.

Marina,
I normally reference the project itself, not the DLL. My understanding is
referencing the project enables VS.NET to better determine dependencies. Or better yet, why does this happen at all?
I believe it happens because the background compilation gets confused. http://www.panopticoncentral.net/arc...03/07/284.aspx http://www.panopticoncentral.net/arc...03/19/291.aspx
Do you have any idea why rebuilding the solution helps?
My theory is the background compilation gets confused, and the Build Rebuild
Solution throws every thing out & does a 100% clean compile, however that is
just my theory.
I know VS.NET 2002 had more problems with then VS.NET 2003 does, at least on
the multi-project solutions that I have worked on.
Hope this helps

Ok, thanks to everyone who took time to look at this.
I guess that 'background compilation' gets confused is about the best answer
as to why 'building' the solution doesn't work but 'rebuilding' it does.
Thanks

news:O6******** ******@TK2MSFTN GP10.phx.gbl... Marina, I normally reference the project itself, not the DLL. My understanding is referencing the project enables VS.NET to better determine dependencies.
Or better yet, why does this happen at all? I believe it happens because the background compilation gets confused.

Do you have any idea why rebuilding the solution helps? My theory is the background compilation gets confused, and the Build
Rebuild Solution throws every thing out & does a 100% clean compile, however that
is just my theory.
I know VS.NET 2002 had more problems with then VS.NET 2003 does, at least
on the multi-project solutions that I have worked on.
Hope this helps Jay

I am referencing the generated DLL.
Oddly enough - chosing rebuild solution does work.
I've gotten used to doing just a build (ctl + shift + b), and I've doing that for probably 3 years and haven't had a problem yet. I guess I'll
have to reassign that to the rebuild command...

Does 'Build - Rebuild Solution' take care of the problem? (instead of modifing the source file).
