did you consider MoveFile(...) for cut n paste operation?

Thanks for the reply..
But I want to implement it in the same way as the explorer does.
That is if I say select any file and say copy it should copy the file to clipbord and I should be able to paste it anywhere.

I have a rtf editor based on dialog box in Visual C++.I have to use this function in my app.When i complile my app, it says undeclared identifier.In documentation says that this fct requires Windows 98.I have this operating system.Then why i get this message?
If this function works it saves my work.
Thanks a lot.

I'm trying to use ShellExecute to display the properties of file, like in explorer. I'm using something like this,
ShellExecute(NULL,"PROPERTIES","c:\\winnt\\notepad.exe",NULL,NULL,SW_NORMAL);
but it always returns code 31, which is invalid verb ("PROPERTIES"). I checked on MSDN, and the verb is correct, and it doesn't seem to be obsolete (I'm testing on a 2000 machine).
Any suggestions on what I'm doing wrong?
Thanks,

try "properties" in lower case and also try using ShellExecuteEx if possiable.

That doesn't appear to make a difference for any of the verbs.

Even I have the same problem.
I am getting the error as ERROR_NO_ASSOCIATION.

From your reply i did some R&D on this, for some reason
"properties" verb does not work with ShellExecute(...) but works with ShellExecuteEx(...)

Try this
SHELLEXECUTEINFO sei;
ZeroMemory(&sei, sizeof(SHELLEXECUTEINFO));
sei.cbSize = sizeof (SHELLEXECUTEINFO);
sei.lpVerb = NULL;
sei.lpFile = m_strexefilename;
sei.nShow = SW_SHOW;
sei.hInstApp = NULL;
sei.lpDirectory = NULL;
sei.fMask = SEE_MASK_DOENVSUBST|SEE_MASK_NOCLOSEPROCESS;
sei.lpParameters = NULL;
if (ShellExecuteEx (&sei) )
return TRUE;
else
return FALSE;
Now start a thread and monitor it, monitor sei

I tried your code with the only change being changing m_strexefilename to a static path for a file. That will open the file just fine, as will setting the verb to "OPEN" or "open". However, if I try setting it to "properties" a message box appears that says:
"This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel."
Any idea what I could be doing wrong?
Thanks,

Also, for any verb, explore, find, etc also give the same visual error.

SHELLEXECUTEINFO
typedef struct _SHELLEXECUTEINFO{
DWORD cbSize;
ULONG fMask;
HWND hwnd;
LPCTSTR lpVerb;
LPCTSTR lpFile;
LPCTSTR lpParameters;
LPCTSTR lpDirectory;
int nShow;
HINSTANCE hInstApp;
// Optional members
LPVOID lpIDList;
LPCSTR lpClass;
HKEY hkeyClass;
DWORD dwHotKey;
HANDLE hIcon;
HANDLE hProcess;
} SHELLEXECUTEINFO, FAR *LPSHELLEXECUTEINFO;
Contains information used by the ShellExecuteEx function.
cbSize
Size of the structure, in bytes.
fMask
Array of flags that indicate the content and validity of the other structure members. This can be a combination of the following values: SEE_MASK_CLASSKEY Use the class key given by the hkeyClass member.
SEE_MASK_CLASSNAME Use the class name given by the lpClass member.
SEE_MASK_CONNECTNETDRV Validate the share and connect to a drive letter. The lpFile member is a Universal Naming Convention (UNC) path of a file on a network.
SEE_MASK_DOENVSUBST Expand any environment variables specified in the string given by the lpDirectory or lpFile member.
SEE_MASK_FLAG_DDEWAIT Wait for the DDE conversation to terminate before returning (if the ShellExecuteEx function causes a DDE conversation to start).
SEE_MASK_FLAG_NO_UI Do not display an error message box if an error occurs.
SEE_MASK_HOTKEY Use the hot key given by the dwHotKey member.
SEE_MASK_ICON Use the icon given by the hIcon member.
SEE_MASK_IDLIST Use the item identifier list given by the lpIDList member.
SEE_MASK_INVOKEIDLIST Use the item identifier list given by the lpIDList member to invoke an application. If this member is NULL, the function creates an item identifier list and invokes the application. This flag overrides the SEE_MASK_IDLIST flag.
SEE_MASK_NOCLOSEPROCESS Leave the process running after the ShellExecuteEx function exits. The hProcess member receives the handle to the process.
hwnd
Window handle to any message boxes that the system may produce while executing this function.
lpVerb
Address of a string specifying the name of a verb. The verb specifies an action for the application to perform. This member defaults to Open if no verb is specified.
lpFile
Address of a null-terminated string that specifies the name of the file to open or print. The function can open an executable file or a document file, but it can only print a document file. If the path is not included with the name, the current directory is assumed.
lpParameters
Address of a null-terminated string containing the application parameters. The parameters must be separated by spaces. To include double quotation marks, you must enclose the marks in double quotation marks, as in the following example:
sei.lpParameters = "An example: \"\"\"quoted text\"\"\"";
In this case, the application receives three parameters: An, example:, and "quoted text".
If the lpFile member specifies a document file, this member should be NULL.
lpDirectory
Address of a null-terminated string that specifies the name of the working directory. If this member is not specified, the current directory is used as the working directory.
nShow
Show flags. Can be one of the SW_ values described for theShowWindow function. If the lpFile specifies an executable file, this member specifies how the application is to be shown when it is opened.
hInstApp
Receives a value greater than 32 if successful, or an error value that is less than or equal to 32 otherwise. Error values can be one of the following: SE_ERR_FNF File not found.
SE_ERR_PNF Path not found.
SE_ERR_ACCESSDENIED Access denied.
SE_ERR_OOM Out of memory.
SE_ERR_DLLNOTFOUND Dynamic-link library not found.
SE_ERR_SHARE Cannot share an open file.
SE_ERR_ASSOCINCOMPLETE File association information not complete.
SE_ERR_DDETIMEOUT DDE operation timed out.
SE_ERR_DDEFAIL DDE operation failed.
SE_ERR_DDEBUSY DDE operation is busy.
SE_ERR_NOASSOC File association not available.
lpIDList
Address of an ITEMIDLIST structure to contain an item identifier list uniquely identifying the file to execute. This member is ignored if the fMask member is not set to SEE_MASK_IDLIST.
lpClass
Address of a null-terminated string specifying the name of a file class or a globally unique identifier (GUID).This member is ignored if fMask is not set to SEE_MASK_CLASSNAME.
hkeyClass
Handle to the registry key for the file class. This member is ignored if fMask is not set to SEE_MASK_CLASSKEY.
dwHotKey
Hot key to associate with the application. The low-order word is the virtual key code, and the high-order word is a modifier flag (HOTKEYF_). For a list of modifier flags, see the description of theWM_SETHOTKEY message. This member is ignored if fMask is not set to SEE_MASK_HOTKEY.
hIcon
Handle to the icon for the file class. This member is ignored if fMask is not set to SEE_MASK_ICON.
hProcess
Handle to the newly started application. This member is set on return and is always NULL if fMask is not set to SEE_MASK_NOCLOSEPROCESS.

Those work perfectly, but I'm not sure how that helps me to display the file properties.
Thanks

Is it possible to save a dialog box like a regular document?
|
|
|
|
|
Well since the CDialog is derived from the CObject then it is well posible to serialize the object.
I believe you need to follow the guidlines how to make an implement serialization.

I need to remove the first ~1 MB or so from some files that tend to be 20 Gig or more.
Is there a way to do this without creating a complete copy of the file? My code currently seeks for the appropriate data in the front of the file, then coppies everything after that point to a new file.
If I could just "delete" the first part, I'd be set.
Any hints?

Can't see how this is possible. I think that the fastest way to copy a large file would be to use memory mapped files.

Still it is going to consume 20gb of extra resource.

Nope. You can simply move the remaining 19.9G in the orginal file. There is no need to copy the file in this particular case. A simple memmove() should do the trick.;)

Well in this case you need either 20gb of physical memory or 20gb of harddiskspace for the swapfile.
