Why are you using malloc() and free() in C++ code, you should be using new and delete. Also why use the call to sizeof(char) in you malloc() call? This is pointless as the size will always be a constant 1.
Check the value of your SampleDocNam_Len and make sure no stupid values are being passed into malloc(), also make sure you are not writing past the end of the array.

I think you should use
GetLine( 0, SampleDocName, SampleDocNam_Len );
instead of
GetLine( 0, SampleDocName);
since for the latter you need to pass the line lenght on the first word of the buffer (MSDN):
lpszBuffer
Points to the buffer that receives a copy of the line. The first word of
the buffer must specify the maximum number of bytes that can be copied
to the buffer.
Also will be nicer if you use the C++ allocation pair new/delete
(you are free to use free of course, but as matter of style...).

Hi, do you guys know how to set(change) the short file name of a specific file inside visual c++? Is there any API doing that?
Thanks!
|
|
|
|

The short file name of a long named file is the first six chars, a ~ and a number, starting with 1 ( depending on how many have those 6 chars ). Not sure if it goes to 5 chars for > 9 files.
You can't set it AFAIK

I think you actually cannot.

If you're on XP+ and the file is on an NTFS volume, you can use SetFileShortName().

Can someone give me a real, WORKING - example(code) of how to "CreateDirectory" , "CopyFile" and "ChangeDirectory" in MFC.
I know how to use these "verbs/tokens" in non-MFC programs, but they aren't available to you in MFC; because you can't "#include <window.h>" in MFC.
So how do you do the same things in MFC. Example code PLEASE!

windows.h is very much included in MFC.
Here's a working sample
::CreateDirectory(_T("C:\\TESTTEST"), NULL);
HANDLE hFile = ::CreateFile(_T("C:\\TESTTEST\\test.tst"), GENERIC_WRITE, FILE_SHARE_WRITE, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL);
::CloseHandle(hFile);
::CopyFile(_T("C:\\TESTTEST\\test.tst"), _T("C:\\test.tst"), TRUE);
::SetCurrentDirectory(_T("C:\\TESTTEST"));

Not true. MFC is a wrapper on Win32, you call any Win32 API you like. Sounds like you have another problem ?

Apparently <windows.h> is already included by MFC headers (AFXV_W32.H).

Thanks. Everyday I learn and learn and learn; but sometimes I forget what I learned.
I never realized that windows.h was included in MFC, so dumb me tried to do everything I wanted to do without using any API functions. You've just made my programming life much, much simpler,
Again thanks.

Hi all,
in my application (MFC MDI Document/View) I use a datagrid and a chart control, each of them in a static splitter pane. Now, I want to provide a different view on my data and therefor I want to open a new child with a "different" view class (derived from CFormView) while the first view is still open. The menu which is displayed should depend on the View which is currently active.
Can anybody give me a hint and show me the pitfalls?
Thank you,
Frank.

Hi All,
This seems such a simple problem, I am embarrassed to ask for help, but I just can't seem to get the syntax correct for the CopyFile command. My application builds a vector of CStrings containing commands in format Copyfile( "source file", "dest file", FALSE ), using double quotes around the file specifications in case there are embedded spaces. The following is one of the commands:
CopyFile( "C:\Documents and Settings\rfickling\My Documents\Expense Report Form.xls", "Expense Report Form.xls", FALSE );
All of these commands fail with an error code of 123, which indicates invalid call syntax. What is wrong here? Can anyone help me with this dumb little problem?
Thanks,
Royce

Don't you escape slashes?

Yes, in the CString.Format() method call you do:
CString str;<br />
str.Format( "C:\\Documents and Settings\\rfickling\\My Documents\\Expense Report Form.xls" );
I am actually formatting these file specs into CString variables so that it looks like the following:
strSrc = "C:\Documents and Settings\rfickling\My Documents\Expense Report Form.xls"; <br />
strDst = "Expense Report Form.xls"<br />
So the command in C++ syntax is:
CopyFile( strSrc, strDst, FALSE );
This should work, but I get a 123 error.

I think the problem is the target file name. You are giving just a filename, so Windows tries to create the file in the current directory.
And what's the current directory?
Try giving a targetname with a complete path, if possible.
Or make sure the current directory is set to where you want the file to be copied to.
SetCurrentDirectory();

The following code works fine on my computer (Win2k):
CString strSrc, strDst;
strSrc.Format( "C:\\Documents and Settings\\Carlo\\My Documents\\Donald Duck.txt" );
strDst.Format( "Donald Duck.txt" );
if ( CopyFile( strSrc, strDst, FALSE )==FALSE)
{
}

Error code 123 is "The filename, directory name, or volume label syntax is incorrect."
Does this help narrow it down?
*EDIT* You shouldn't have to add any double quotes because of spaces.

Thanks for the help, guys. I found that my problem was using the double quotes around the file paths and not specifiying a filename in the 2nd parameter.

I recently had some code sent to me by a user of one of my articles that improved the functionality of my article. The code is designed to work with VC8. But as I want the code to work on VC6 and up I have to put guards around it. So my quuestion is what version of VC introduced the __FUNCTION__ macro and what version introduced the __noop keyword?

I believe __FUNCTION__ was first introduced in VC7, which was my final straw to upgrade from VC6. As for the __noop, I'm not sure.

__noop also added in VC7

Thanks
I am assuming you mean VC7.0 (2002), not VC7.1 (2003)
