Re: "Windows (Vista) cannot find “abc.def”. Make sure you typed the name correctly and then try again."

16-Jul-09 13:25

In Windows Vista (only) when I double click on a file in Windows Explorer that is associated with my application Vista displays: Windows cannot find "abc.def". Make sure you typed the name correctly and then try again." Where abc.def is the file I double click on in Explorer and it is associated with my app.

My app starts, if it isn't already running and the file does get opened correctly. Likewise if my app is already running the file is opened correctly. But this error is always displayed.

If instead I use "Open With" and select my app the file opens and no error is displayed.

I've Google'd and found various posts from people getting this error with Word, Excel files etc. but no real solution.

Neville - a suggestion - why not use Process Monitor[^] to see what Windows is actually looking at - you may well find the operation that can't find abc.def, and that might give you the clue you need to solve the problem?

That's what I'd do, anyway! Smile | :)

Thanks Stuart. I just tried PM and scanned several thousand log entries but nothing really stood out. MS has changed (broken) various aspects of File Associations with Vista and MFC in VS2008 has not been updated to address these issues. That said I don't think this is the cause of the error. It seems as though Windows Explorer is misreading what is going on.

Mostly to do with DDE from what I've read?

Yes DDE no longer works in Vista from Explorer, yet CDocManager::RegisterShellFileTypes() still registers as a DDE client. Further RegisterShellFileTypes() still uses HKEY_CLASSES_ROOT which can't be used on Vista. There is a Linker option "Per-User Config" and AfxSetPerUserRegistration() which I assume trigger RegOverridePredefKey() so HKCR morphs across to HKCU. And finally Vista has a new IApplicationAssociationRegistration::SetAppAsDefault Method which adds an app to the list of Default Applications and uses HKCR!!!

It only took me most of yesterday to get to the bottom of this. (:

Well I'll be testing that next. But one has to assume (pray/hope) it is the same as Vista.

I think I've finally found the cause which is a lurking HKCR shell\open\ddeexec = [open("%1")] entry. I thought I'd got rid of these, but this one reappeared. Maybe I'll end the week (Oz) on a good note after all.

Im looking for documents(programming languages) that would guide me in creating an interface that reads network data. So i guess i should start by creating the interface or finding out how to read network data and input database.

You will probably be more sucesful if you slit that work into separate tasks. For instance, learning how to create a UI is completely independant on learning how to read the network data. What is your experience in programming ? Did you already develop some programs with a UI ?

Yes, you can have many source files in a project.

like i want to get output for this code:

node center=G.new_node(); //create new node "center" of G

int i;
for (i=0;i<100;i++) {
node v=G.new_node(); //create new node v of G
G.new_edge(center,v); //create new edge of G
//with source center and target v
}

edge e;
forall_edges(e,G) { //iterate over all edges e of G
node source=G.source(e); //compute source of e
node target=G.target(e); //compute target of e

std::cout << "edge ";
G.print_edge(e); //print edge
std::cout << " has source ";
G.print_node(source); //print source
std::cout << " and target ";
G.print_node(target); //print target
std::cout << std::endl;

Rename the second one so it's called something other than main and call it from the first main. You'll also need to tell the first main about the renamed function:

first_main.cpp

// Whatever #includes you have

extern int second_main(int argc, char** argv);

int main(int argc, char** argv)
{
   // Whatever the first main does


   return second_main(argc, argv);
}

second_main.cpp

// Whatever #includes you have

int second_main(int argc, char** argv)
{
   // Whatever the second main does


   return someValue;
}

Converting very old VC++ to VS2005 and MSXML

Not if it's a console app - the C runtime library wants to link to the main from your app. If your app has two mains, then there will be an ambiguity; the runtime won't know which main to link with.

Similarly, a GUI Windows app is looking for WinMain (or wWinMain if you're using Unicode). You can't have two WinMains in a GUI app.

In the same process? Make them functions that execute in separate threads[^].

Folks,
I have a project I'm trying to convert from VC++ MFC to VS2005, and I'm having a problem with msxml (and I know NOTHING about MFC -- have never coded in it).

Basically, there is an msxml.cpp/.h in the project directory, and when I compile, I am getting type redefintion errors.

MSXML.cpp
e:\....\graphing\mpactgrafx activex control\msxml.h(972) : 
 error C2011: 'XMLDOMDocumentEvents' : 'struct' type redefinition
 c:\program files\microsoft visual studio 8\vc\platformsdk\include\msxml.h(9495) : see declaration of 'XMLDOMDocumentEvents'

in the PROJECT msxml.h:

class XMLDOMDocumentEvents : public COleDispatchDriver

and in the platformsdk\Include\msxml.h:

XMLDOMDocumentEvents : public IDispatch

Looks like it is pulling in not only the local msxml (which is what I want it to use), but also the
c:\program files\Microsoft Visual Studio 8\VC\PlatformSDK\include\msXml.h

so I am getting the redef in the project msxml stuff.

I don't see any real way to EXCLUDE only that platformSDK\Include\msxml.h file during compilation.
I've tried the tools->options->project..-> VC++ directories, but if I exclude that platformSDK\include, I get all sorts of badness happening.

If I get rid of the local msxml.h/cpp, I also get bad things happening (due to used objects from that old msxml missing)

Any help greatly appreciated.

Stuart Dootson16-Jul-09 9:39

Add your local directory to the C++->General->Additional Include Directories property (Debug AND Release). That should mean the compiler sees your local msxml.h before (and instead of) the Platform SDK one.

Or, change the msxml #includes to

#include "./msxml.h"

I think that might work as well?

Thanks -- actually DID include the local dir to resolve a few other issues -- this one is the only one I have left outstanding at the moment (at least until THIS one clears and the compilation finds something else WTF | :WTF:

)

I have tried the "./msxml.h" also, but I am still getting that error message (I even put in the entire path, same result).

Well, that's spooky.

Have you changed ALL #includes of msxml.h? Try checking stdafx.h and rebuilding from scratch.

Yeah, really strange.

There are only two references to #include "msxml.h" in the project:
1)a generated MSXML.cpp file
2)a DataParse.h (which is where a bunch of custom parsing code is defined).

No other #include of msxml.h at all!! Confused | :confused:
