We are using CComModule class in atl6.0. But it looks like the same class is change to CAtlComModule in atl8.0

Even though there are some changes. Component made under VC6, and again converted on VS2005 will not fail to register.

Try putting break point in DllRegisterServer, and see where it fails.

Hi all,

It appears that there is some length restriction in VC++ 6.0 for the "Additional include directories" field. This is under Project-> Settings-> C/C++ tab -> Category: Preprocessor. Due to the specifics of the component I am working on I cant decrease the number of inlude paths that I have to enter in this field and at some point on VC just stops to accepts anymore paths and sh*ts start to happen. Ive tried to enter the paths manually in the dsp file but with no success. If someone has a solution for this, please help!

Note that a solution should mean that all include paths I need have to be stored somewhere in the project or at most in a file attached to the project in such a manner that if someone else wants to review my component one should only download it from the Source Safe Server and run it without any additional modifications in his side!

Approximate size for the additional include directories string I am trying to enter: ~3k Smile | :)

You've got to be kidding WTF | :WTF:

You could use the SUBST command to set up some drive aliases for common base directories, maybe create a batch file to set them up. Not an ideal solution but if you've got 3000+ characters of include paths already, I think you've got bigger problems as it is Roll eyes | :rolleyes:

I am not kidding. Project is big. Lots of components. I need them all. The path names are long themsleves too. SUBST cant be used because the idea is to copy the project on another machine and it should work without doing subst there.

I have seen this problem reported before but did not find any solution. I know its ridiculous but this is the situation! Anyone who knows how to deal with this problem is welcome!

Consider this example:

Suppose your projects are setup in the following paths:

c:\MyProjects\common\include
c:\MyProjects\DLLs\DllProject1\include
c:\MyProjects\DLLs\DllProject2\include
c:\MyProjects\Project1\include

Lets suppose Project1 needs the includes from DLLProject1, DLLProject2, and common\include.

You could enter the include paths for Project1 using relative paths, relative to the Project1 project folder. Using the above example, your include path could be:

.\include;..\common\include;..\Dlls\DllProject1\include;..\Dlls\DllProject2\include

Alternatively, you might be able to use evironment variables (macros) in the include path. What you could do is define environment variables that define common directory paths into a single macro.

Using this technique, you could define these environment variables.

SET PROJECTBASE="C:\MyProjects\"
SET COMMONINCLUDE="%PROJECTBASE%common\include"
SET DLLBASE="%PROJECTBASE%DLLs"

Your include path would be:
.\include;$(COMMONINCLUDE);$(DLLBASE)\DLLProject1\include;$(DLLBASE)\DLLProject2\include;

The basic idea is to merge as many common folders into a single macro.

The IDE will automatically expand the $(<environment variable>) macros as needed. Using this technique makes it real easy to move your projects from one folder to the other without having to tweak each of the projects. You just have to adjust the environment variables.

I hope this information helps you or at least gives you ideas on how you can solve your include path problems.

This subject could be a good idea for a beginners article here on CP.

Hai..
Iam using SHFileoperation to copy folders..
While copying those i need to show progress bar.I was able to do that upto some extent by using FOF_SAMPLEPROGRESS.
But in this it is not showing the file names which are being copied.
How to show the file names in the progress dialogbox??Can any one help me out..

Thanks in advance.

Its this flag causing it, have you seen its MSDN description ? It says,
Display a progress dialog box but do not show the file names.
Can you show code, what you are doing ?

This code just work perfect for me,

SHFILEOPSTRUCT sfo;
sfo.hwnd = NULL;
sfo.wFunc = FO_COPY;
sfo.pFrom = _T("F:\\FromFolder\0");
sfo.pTo = _T("c:\\TargetFolder\0");
sfo.fFlags =  NULL;
SHFileOperation(&sfo);

Thanks for reply..
The code is working perfectly 4 me..almost similar to you...
Are you getting the file names in the progress dialog box..
Ya i used FOF_SAMPLEPROGRESS, it is without file names.
I want with the file names.Generally we will get the file names also, right when we are copying files.
How to get it??
Thanks.

I asked you to remove FOF_SIMPLEPROGRESS flag. Definitely , you have not read my first reply.
Your code should be like this,

SHFILEOPSTRUCT SHFileOp;
ZeroMemory(&SHFileOp, sizeof(SHFILEOPSTRUCT));
SHFileOp.hwnd = NULL;
SHFileOp.wFunc = FO_COPY;
sPath+='\0';
SHFileOp.pFrom=sPath;
DestPath+='\0';
SHFileOp.pTo = DestPath;
SHFileOp.fFlags = FOF_NOCONFIRMMKDIR/*|FOF_SIMPLEPROGRESS*/; 
//The Copying Function
SHFileOperation(&SHFileOp);

And use <pre> tags , while posting the code.

Have a look at the

typedef struct _SHFILEOPSTRUCT {
    HWND hwnd;
    UINT wFunc;
    LPCTSTR pFrom;
    LPCTSTR pTo;
    FILEOP_FLAGS fFlags;
    BOOL fAnyOperationsAborted;
    LPVOID hNameMappings;
    LPCTSTR lpszProgressTitle;
} SHFILEOPSTRUCT, *LPSHFILEOPSTRUCT;

structure.

I.E:

wFunc
Value that indicates which operation to perform. This member can be one of the following values.
FO_COPY
Copy the files specified in the pFrom member to the location specified in the pTo member.
FO_DELETE
Delete the files specified in pFrom.
FO_MOVE
Move the files specified in pFrom to the location specified in pTo.
FO_RENAME
Rename the file specified in pFrom. You cannot use this flag to rename multiple files with a single function call. Use FO_MOVE instead.

Have a look Here[^]

Thanx prasad that helped me aswell, can the same be applied to files ??? To show file cpoy progress.

Yes,

FOF_ALLOWUNDO  Preserve Undo information, if possible. If pFrom does not contain fully qualified path and 
	filenames, this flag is ignored.  
FOF_CONFIRMMOUSE  Not currently implemented.  
FOF_FILESONLY  Perform the operation on files only if a wildcard file name (*.*) is specified.  
FOF_MULTIDESTFILES  The pTo member specifies multiple destination files 
	(one for each source file) rather than one directory where all source files are to be deposited.  
FOF_NOCONFIRMATION  Respond with Yes to All for any dialog box that is displayed.  
FOF_NOCONFIRMMKDIR  Does not confirm the creation of a new directory if the operation requires one to be created.  
FOF_NOCOPYSECURITYATTRIBS  Version 4.71. Microsoft® Windows NT® only. The security attributes of the file 
	will not be copied.  
FOF_NOERRORUI  No user interface will be displayed if an error occurs.  
FOF_RENAMEONCOLLISION  Give the file being operated on a new name in a move, copy, or rename operation 
	if a file with the target name already exists.  
FOF_SILENT  Does not display a progress dialog box.  
FOF_SIMPLEPROGRESS  Displays a progress dialog box but does not show the file names.  
FOF_WANTMAPPINGHANDLE  If FOF_RENAMEONCOLLISION is specified, the hNameMappings member will be filled in 
	if any files were renamed.

Hi all:

As we all know messages must involve with specific window's handle, but I come across a requirement that there's no window handle available, but still I want a sub thread to send a WM_QUIT(PostQuitMessage(...)) message to main thread, in order to stop the main thread's

while (GetMessage(&msg, NULL, 0, 0))<br />
{<br />
    TranslateMessage(&msg);<br />
    DispatchMessage(&msg);<br />
}<br />

Send a PostQuitMessage from sub thread doesn't seem to work.

To send message you should have a window handle, to send message to that specific window. or you can broadcast the message but in your case its WM_QUIT, so you can not boardcast it. Better you can pass the window handle to the thread at the time its creation and use the handle to send the message

This would post WM_QUIT message to that threads(sub) message queue, if there is any.

So in this case you should follow suggestion by Naveen.
