Just tested it with exactly your code. Same 632 error.

RasError.h says :

#define ERROR_INVALID_SIZE (RASBASE+32)
/*
* An incorrect structure size was detected.
*/

And I swallow a small raisin.

I have just tested the code you have forwarded me :

RASWrapper.EnumConnections --> fails
RASWrapper.RasEnumDevices --> ok
RASWrapper.EnumEntries --> fails

Does it fail (iow return != 0) ? If so, state error code plz.

It wont return values if u dont have an active dialup connection(s).

The return value in both cases is 632.

Indeed, that's what I was wondering, as I am not using dialup at all to connect.

Hmm, very strange....

These are my struct sizes with the results executed in the same order as the file i sent you.

EnumConnections
Size: 704
Result: 0

EnumDevices
Size: 152
Result: 0

EnumEntries
Size: 528
Result: 632

The API is bad for marshalling Frown | :(

Maybe in C++ its easy, but I cant think why the function works so "stupidly".

To avoid these number problems, wouldn't it be of interest to marshall a simple pointer, ie forget about SizeConst, ...
At least, this would be simplify marshalling.

As specified by MSDN:

LPCTSTR reserved, // reserved, must be NULL

Now THIS NULL is an int that must be set to 0 and NOT null as in a null object. Then everything works as it should.

Re other post about MAX_PATH, this one required 260, the other struct required 256. WTF is going on????

Error with shdocvw.dll, while building a .msi

Hello

When I build my .msi, I get this error :

ERROR: 'shdocvw.dll' should be excluded because its source file
'C:\WINDOWS\System32\shdocvw.dll' is under Windows System File Protection.

So the .MSI package is built anyway, but the installed application doesn't
work because a file is missing ( the application works, except when I try to print or to show a preview. These functions use printDialog, printDocument, printPreviewDialog ...).

How do I include this component?

Thanks

yes
It doesn't work, because I can't make the link with the .exe

But this dll is present on the user machine. I think that we must use the dll present on the user machine.

Hi troz

Whne adding shdocvw.dll as a reference, it automatically creates Interop.shdocvw.dll in the application folder. This file is the one that should be added to the msi (and set to copy local, we wnat the file there). Leave the other file out of it. Smile | :)

Hope this helps Smile | :)

yes this file is created in the application directory, and added directly to the .exe dependancies. It's installed in the installation directory.
But this doesn't solve the problem.

Maybe the pb with printing doesn't come from this dll ???

but I see that the dll isn't loaded when the application runs

the error message is :

Many system dlls follow a delay-load scheme, even if they are statically linked. The delay load is accurately displayed in Dependency Walker.

If you want to know what dll does the actual PRINT, I suggest to build a small project embedding IE. And exec the OLECMDID_PRINT command to the current HTML Document.

And I swallow a small raisin.

- shdocvw.dll is not a redistribuable by itself. It is part of the Internet Explorer gloubiboulga and if you copy this file, you'll certainly miss sister dlls such like urlmon.dll, mshtml.dll, ...

- you need to do one of these :

- get the equivalent merge module (.msm) file provided by MS. Check out the redist.txt file in your MSDEV CDs for the list of .msm files. A .msm is a binary package which is properly handled by .msi databases.

- redistribute the IE package.

And I swallow a small raisin.

Hi,

I have two Queries...

First:

Is there any way by which I can Specify (In my Assembly itself) that
the CopyLocal Property of a Reference to my Assembly should be False?

ie: Whenever my assembly is added into any Project (References), the
CopyLocal property for that Reference should be False by default.

Note: It should be possible without making the Assembly Strong Named.

And,

Does the Framework/VisualStudio IDE raise any Event or send any kind of
Notification to the Assembly when a Reference to it is Added or Removed from a Project.

ie: I want to execute some code from within my assembly when that Assembly is
Added or Removed from the References collection of any Project.

Thanks,

Firoz

As far as I know/remember once a project has been saved, that setting should persist when adding it to a new solution, unless the assembly is not available.

Hi Leppie,

Thanks for your Reply.
But, thats not the problem.
I will explain it in Detail.

I have created a simple UserControl.
There are some limitations(or you can say Bugs) in this control.
One such limitation is that the CopyLocal property of the Reference
to this Control should always be FALSE.

When this control is added to the References of any project,
by default the IDE makes the CopyLocal property of the reference to TRUE.

Now, this Control is used by some other developers also.
and, I cannot ask or expect those guys to manually change the CopyLocal
property from True to FALSE everytime they add my control to their Projects.

So, I need a WAY by which the CopyLocal property should be FALSE automatically whenever my Control is added to any Project.

Actually, I feel(or wish) there is some simple way to do this.
Like some Assembly Arributes which will expose the Value for CopyLocal
property and the IDE will read it from the Assembly when it is added to the Reference and set the CopyLocal property accordingly.
But, I could not find any such Attribute...

Thanks,

Firoz

Yes, you can. It is a registry entry somewhere, and if you are using Win 2000/XP , you can run the group policy editor, by running gpedit.msc from start run. Unfortunately, I cant point you to the correct place in the registry.
