Michael Dunn has written some excellent articles here on CodeProject about this topic - trying looking for his articles.

What you require is a 'shell extension'.

Andrew,
thanks.
i did read part of his articles (1-9) before - all are in COM.

i really don't like COM.
i think there must be simple way to do that - may be we just need to modify register, similar to doing for double-clicking a file.

cheers

Which file type's context menu are you interested in modifying?

when we right click a file in Explorer, the munu pops up.
we can see WinZip or "Send to" folder on it.

file extension can be any, i.e. .mytype or .class

There is no single way to do this. If you are wanting to add to a context menu that already exists (e.g., the one that pops up when you right-click a .dll or .cda file), you have one set of steps. For example, if you wanted to add to the context menu of a .dll file, you could save the following to a .reg file and merge it into the registry:

Windows Registry Editor Version 5.00
 
[HKEY_CLASSES_ROOT\dllfile\shell\Calc]
 
[HKEY_CLASSES_ROOT\dllfile\shell\Calc\command]
@="c:\\winnt\\system32\\calc.exe"

If you are wanting to create a new context menu for an extension not yet registered (e.g., .mytype), you have a different set of steps.

does "a different set of steps" mean i must use COM as suggested in previous replies?

Not necessarily. What do you have against COM anyhow?

It requires just a few more entries in the .reg file:

Windows Registry Editor Version 5.00
 
[HKEY_CLASSES_ROOT\.mytype]
@="MyType.Document"
 
[HKEY_CLASSES_ROOT\MyType.Document]
 
[HKEY_CLASSES_ROOT\MyType.Document\shell]
 
[HKEY_CLASSES_ROOT\MyType.Document\shell\Calc]
 
[HKEY_CLASSES_ROOT\MyType.Document\shell\Calc\command]
@="c:\\winnt\\system32\\calc.exe"

As has already been mentioned, this sort of stuff is explained in Michael Dunn's shell articles.

you are talking about how to use double-clicking of a kind of file.

i modified register as your comment, but i saw nothing on popup menu of Explorer.
when i double clicked some.mytype, calculator was running.

it is not right answer of my question.

i read Michael Dunn's articles again, i can not find hint about my question.

he added a program to menu folder "send to" of popup menu of Explorer by
::SHGetSpecialFolderLocation(0,CSIDL_SENDTO,&pidl)
i will try to get answer from that point.

When you right-clicked an item that had a .mytype extension, you should have seen Calc at the top of the context menu. The fact that it was bold meant that it was the default option. That's why double-clicking the item started the calculator.

My example was merely that - an example. You may need to extrapolate from the examples to get what you want. Not all shell items are the same so there is no one-size-fits-all solution.

DavidCrow,
i think maybe something is wrong with my test.

@=mytype.document
what does it exactly mean under key of .mytype?

if we open regedit, it looks
name ------------ data
default --------- @=mytype.document
or
@ --------------- mytype.document
or
other format??

Hi!

I was wondering if anyone would be so kind to show me some complete sample code on how to use a MSAgent in Visual C++ .NET. I am having some trouble figuring it out also because of my limited C++ knowledge Blush | :O

Thanx

Check out my C# articles for algorithms for edge detection. Once you detect the edges, then you can compare them. That's not to say the rest is easy, but if you can detect outlines, then you can attempt to map them, and see how similar they are.

problem while opening files from multiple directories

hi!
i'm creating a media playing.. using MCI .... the app dosen't play files from multiple directories... though they are added to the listbox.. they are not played .
The problem is that i want to load files from multiple directories and it plays files only from one directory... i.e the one from which the files were last loaded from. the files that were loaded from other directories do not play - V.G

Re: problem while opening files from multiple directories

David Crow8-Nov-04 10:44

What do you mean by "do not play?" Do you receive some sort of error message? Since paths are involved, are you confusing absolute with relative paths?

This doesnt compile as AccessB is unresolved in E . I dont want an implementation of AccessB in E , What needs to be changed ?

Re: Inheritance

Michael Dunn8-Nov-04 6:49

It doesn't compile because the AccessB() call is ambiguous. It could be D::AccessB() or A::AccessB(). Change it to either of these, depending on which function you want to call:

bPtr->D::AccessB();
bPtr->A::AccessB();

Hi,

I'm having a problem passing command line arguments in VS 2003 without opening a command prompt. The link below shows a picture of my debugging properties dialog box. My command arguments are set as shown in the picture. When I run the program in debug mode from the IDE, argc is always equal to 1, regardless of the content of the command arguments edit box. I don't have this problem when I do the same procedure from the command prompt.

What am I missing?
