DNCompInfo​.dll : Error message in debug window

Question

Hello
I am currently working on a DLL, which is loaded by an Labview program.
Today, I allways see the following message in the debug window of Visual Studio:
<mda:msg xmlns:mda="http://schemas.microsoft.com/CLR/2004/1​0/mda">
  <!--
       Die DLL &quote;C:\Programme\National Instruments\Shared\LabVIEW
       Run-Time\7.0\DNCompInfo.dll&quote; unternimmt einen Versuch, innerhalb der
       Sperre f?r den OS-Loader eine verwaltete Ausf?hrung durchzuf?hren. Versuchen Sie
       nicht, verwalteten Code innerhalb einer DllMain- oder
       Bildinitialisierungsfunktion auszuf?hren, da dies ein H?ngen der Anwendung zur
       Folge haben kann.
   -->
  <mda:loaderLockMsg break="true"/>
</mda:msg>
I can not remeber to see this ever before. Do you know, what's the reason for this mesage?
The message appears, when I stop working with the program.

Answer 1

Hello
I try to explain what I am exactly doing.
We have an application, which is build in Lab View. This application uses a DLL
to communicate to a special hardware, which is written by me in Visual C (Version
6.0). We do not use .NET in the DLL, nor explicit in the Lab View application (maybe
Lab View uses it internally, I do not know).
The message appears, when I stop working with the program. I exit the
application, and I can see several messages in the Debug Window of Visual C about
unloading DLL’s and exit threads, which is OK. The last message of this kind is
the message I am talking about.
I try to
translate it, maybe it will become more clearly to you:
“The DLL <DNCompInfo.dll>
tries to execute managed code inside the lock from the OS-loader. Do not try to
execute managed code inside of DllMain or Image-initialisation (?), because this
can hang/lock/crash (?) the aplication. “
So I hope, this
will become clearer now. The message only appears in the Debug Window, so I
think a “normal” user will never see it.
