Using the following:
VC++ 6.0/sp5
Win2K, Win95, and Win98
Our app uses some proprietary file formats and of course, the appropriate file types are associated with our app. However, when I double-click an associated file type, I get a message that is generate by windows that reads:
Cannot find the file "full path/name of file I clicked on" or one of it's
components. Make sure the path and filename are correct and that all
required libraries are available.
The path\filename are correct, and all of the required libraries are available. In fact, if I just load the app and open the very same file from within the app, it opens fine. Similarly, if I pass the desired filename in on the commandline, it opens fine. I can also drag a file onto the app window, and it will open without complaint.
At the top of OnInitInstance(), I have added the following code:
CString sCmdLine = ::GetCommandLine();
AfxMessageBox(sCmdLine);
The resulting string shows this (including all quote marks shown):
"D:\path\myprogram.exe" "
When I manually pass the filename in on the commandline, the same string shows this:
"D:\path\myprogram.exe" "D:\path\myfile.xyz"
What the heck is wrong here?

Everything looks good on the paths and filenames (as they show up in explorer).
Could something be funky in the registry?

maybe the file association links got trashed?

How are you doing the association - and does the error happen with files with spaces in the name ?
If so the
shell\open\command default value might be this
<your app="" path=""> %1
try this
<your app="" path=""> "%1"
ensures that the spaces are treated as one full string instead of multiple files
also try
"<your app="" path="">" "%1"
if that doesn't work

Sorry that last message did't work quite right

The problem may be in the registry. Look at the default value under HKEY_CLASSES_ROOT\.xyz (the value is noted <the_value> below).
Then look at the default value of the following key, that may be the cause of the problem:
HKEY_CLASSES_ROOT\<the_value>\shell\open\command
May be this string is just wrong (messed up quote or something).
I hope this helps,

I'm using Wise 9.1 for instalations, and for some reason, it's translating this:
"%MAINDIR%\myapp.exe" "%1"
to this (showing as it appears in the registry):
"D:\program files\mycompany\myapp\myapp.exe" "

adding another "%" to the original line fixed the basic problem, but I'm still getting this
Cannot find the file "full path/name of file I clicked on" or one of it's
components. Make sure the path and filename are correct and that all
required libraries are available.
weird.

I know it has been a while, but did you ever find out what was causing this? I am having the same problem and it is driving me crazy.

Geeze - I'll have to go back and see what I did, and it will have to wait until tomorrow because that's work stuff, and I'm at home.

I've got a small SDI app. I have a bunch of settings I want to retain in between program loads. Where is the "proper" place to store them among the MFC classes that ClassWizard creates? Do I declare a struct in my CChildView class, or put it in CMainFrame?
On a more general note, if there's anybody that uses Sonork or ICQ or IRC and wouldn't mind me occasionally bugging them for a small finicky question like this every now and then, I'd appreciate the help. Until then I'll keep asking here and waiting patiently for CG to respond.

I tend to make them either members of the document class or the app class depending on where they need to be used.
If there is a lot of them I will create a seperate class and have that be a member of the CDocument/CWinApp derived class.

Yeah.. I didn't explain myself correctly. I plan to use the registry anyway, but I just wonder where the best place is to put the settings after I pull them from the registry.

I tend to place the view specific settings in the View class and the document specific settings in the Doc class. And any setting that is common to all views/docs (if it is an MDI), in the App or MainFrame.

How do we feel about directly calling framework handlers?
I'm talking about setting up a DC and calling OnPaint(). I'm talking about calling the WM_COMMAND handler for a specific menu item.
Personally, I find this quite lazy. What should be done it to create a routine that does the required action, and then have both the framework handler and the user code call the routine.
Am I psycho?

Somehow, I find this a little less elegant.

I think that it is fine, as long as only your class can call the framework handlers directly. The way that I look at it, is you are combining common functionality into one place. That common code needs to be accessed.
Do what makes the most sense for the situation. Whether it is sending a message to the window and letting the message handlers process the message, or calling the framework handler directly.

Hi !
In my current MFC source code, I have two classes, the usual "MainDlg" and .. euhm ..let´s say "A", which is not a CDialog based class, but another kind of class running separately (in its own thread). In a function of A, I send a message with PostMessage(MSG_MYMESSAGE,35,47); and I´d like to get it in my MainDlg. A way to do this is to declare :
<br />
BEGIN_MESSAGE_MAP(CMainDlg, CDialog)<br />
ON_MESSAGE(MSG_MYMESSAGE, OnMyMessage)<br />
END_MESSAGE_MAP()<br />
This triggers the OnMyMessage() function, but i do not know where to find my two parameters 35 and 47 (that is, the WPARAM and LPARAM), and I really need them.
So, is there any way to get these parameters ?
Thanks 4 your help.

run just one more test before I leave, in which case

your header file message map entry should look like:
afx_msg LRESULT OnInitTimer(WPARAM wParam,LPARAM lParam);
your cpp file function dec should look like:
LRESULT C8028CDlg::OnInitTimer(WPARAM wParam,LPARAM lParam)
{
wada wada
}
the lParam and wParam are the numbers you want
