I only get a 8.3 format filename through following code, and I want to get a long filename, how?
HINSTANCE hInst = AfxGetInstanceHandle();
if(FAILED(!hInst)) return E_FAIL;
CString strDllFileName;
DWORD Status = GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName, MAX_PATH);
TRACE(strDllFileName);
by debugging, I find that the value of strDllFileName is F:\hu\DD\DETAIL~1\Debug\DETAIL~1.DLL, and the corresponding longname is F:\hu\DD\DetailDesign\Debug\DetailDesign.dll
Note:
I am programming in VC++ 6.0, my Operating System is Windows XP, the Disk F: ,where the .dll file is located, is NTFS format.
Thank you very much!!!

Have you considered GetLongPathName()?

Hello
you can try this function which transform the path you get from GetModuleFileName...
<br />
typedef DWORD (__stdcall *GETLONGPATHNAME)(LPCTSTR, LPTSTR, DWORD);<br />
<br />
DWORD MyGetLongPathNameEx (CString& sPath)<br />
{<br />
DWORD dwRet = 0;<br />
<br />
HINSTANCE hdl = ::LoadLibrary ("KERNEL32.DLL");<br />
if (hdl == NULL)<br />
return dwRet;<br />
<br />
GETLONGPATHNAME pfnGetLongPathName = (GETLONGPATHNAME) GetProcAddress (hdl, "GetLongPathNameA");<br />
if (pfnGetLongPathName == NULL) {<br />
::FreeLibrary (hdl);<br />
return dwRet;<br />
}<br />
<br />
dwRet = (pfnGetLongPathName) (sPath, sPath.GetBuffer (_MAX_PATH), _MAX_PATH);<br />
sPath.ReleaseBuffer ();<br />
<br />
::FreeLibrary (hdl);<br />
return dwRet;<br />
}<br />
<br />
<br />
CString strDllFileName;<br />
DWORD Status = ::GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName.GetBuffer (_MAX_PATH), _MAX_PATH);<br />
strDllFileName.ReleaseBuffer ();<br />
DWORD dwRet = ::MyGetLongPathNameEx (strDllFileName);<br />
TRACE(strDllFileName);<br />

use GetLongPathName after u have got the short file name.
I would like to comment that the statement
DWORD Status = GetModuleFileName (hInst, (LPTSTR)(LPCTSTR)strDllFileName, MAX_PATH); is wrong.
u should never cast CString like (LPTSTR)(LPCTSTR)strDllFileName. U may have unexpected results because of this. Use as follows
DWORD Status = GetModuleFileName (hInst, strDllFileName.GetBuffer( MAX_PATH ), MAX_PATH);
strDllFileName.ReleaseBuffer( -1 );

Let me try to actually answer the subject of ou post...
That function dates back to 16-bit Windows, and my guess is that since only FAT-style 8.3 filenames were supported, Win32 inherited that behavior.
Also, note that the GetModuleFileName(...) function is one of the few that is capable of returning filepaths longer than MAX_PATH, so do not assume that MAX_PATH is always going to be long enough...
Peace!

Hi!
Does somebody know, what I have to do, when there is a .rtf-File which should be converted to a WinHelp-File? I don't have a .cnt but a .hpj-File.
Thanks a lot, Hanno

You can open the Help Workshop tool provided with VS 6.0
In the help of Help workshop you can get the step by step procedure for developing the winhelp file.

As it happens, the plans for my next project is to create a HTMLhelp helper which would be able to do just this. As an alternative for now, you could open the file with MS word and save it as a HTML file, then compile it with the HTMLhelp utility. The problem with this is the HTML files are very bloated, so you might want to edit out all the nonsense with a text editor.

Sorry, I misread the title of your post as HELP-File whereas HTMLhelp actualy creates .chm files.

Hi,
can anyone plz tell me what may be the error ???

you forgot to #include the header which contains the definition of the CCreateDlg...
|
|

|
|
// UpdateDlg.cpp : implementation file
//
#include "StatusDlg.h"
#include "stdafx.h"
#include "DesktopSearch.h"
#include "CreateDlg.h"
#include "UpdateDlg.h"
#include "FoldersDialog.h"
I have added CreateDlg.h but still i am getting the same error
|
|

|

read my other answer...
you included the headers in the wrong file
|
|
|
|
|
Have you included the CreateDlg.h in you UpdateDlg.cpp file..??
if not then include it and try to bulid the application
CreateDlg.h file having the class definition of CCreateDlg class

you didn't read the errors properly :
d:\parichay\desktopsearch\desktopsearch\updatedlg.h(54)
you have to #include "CreateDlg.h" in the UpdateDlg.h !
one last thing :
move the "stdafx.h" include at the top of all other includes to avoid compilation problems due to the use of precompiled header.

Hi ,
just wondering :
Are you sure that your class's name is CCreateDlg and not CreateDlg(when creating a class with 'C' as a first letter - the class wizard , from some reason does not add the prefix 'C' to the claas name... ).
Regards,
Eli

|

|

you're wrong eli.
the class wizard removes the leading C to the file names containing the definition and the implementation of the class beeing created, not directly on the class name.
moreover, look at the errors returned by the compiler :
d:\parichay\desktopsearch\desktopsearch\updatedlg.h(54) : error C2501: 'CCreateDlg' : missing storage-class or type specifiers
yes, the class is effectively CCreateDlg
|
|
|
|
|
Hi v2.0.
You are right
I didn't see that he included the CCreateDlg header file in the Updatedlg implementation file and NOT in the UpdateDlg header file.
About the class wizard - for some reason , in my projects , the class wizard removes the leading C from the class name as well.
With best regards,
Eli

Do you realy have a sub directory called desktopsearch inside the directory with the same name?
|
|
|
|
|
I think the error is because you are cross-including files; I mean including fileA.h in fileB.h and fileB.h in fileA.h etc. You could just declare the class like:
class CCreateDlg;
Then declare a pointer:
CCreateDlg* m_pDlg;
etc.
this is this.

Hi,
i have new button on sigle click i want a dialog window to open i have declared variables as follows..
can anyone help to solve this problem..??

CStatusDlg m_dStatusDlg;
class CCreateDlg;

// UpdateDlg.cpp : implementation file
//
#include "stdafx.h"
#include "DesktopSearch.h"
#include "StatusDlg.h"
#include "CreateDlg.h"

I don't think you are very familiar with pointers and their uses. Using the pointer to declare the variable would mean that you have to give it memory by using the new operator. Then create the dialog using Create(...) then show the dialog using ShowWindow(...).
This could be the code:
class CCreateDlg;<br />
CCreateDlg *m_dCreateDlg;
Now on button-click:
m_dCreateDlg = new CCreateDlg();<br />
m_dCreateDlg->Create(IDD_WHATEVER);
m_dCreateDlg->ShowWindow(SW_SHOW);
This would create a modeless dialog.
Note that this would give memory leaks if you do not dispose if off correctly. And if you want to re-use the pointer to create the dialog again, there could be problems.
Another way would be:
m_dCreateDlg = new CCreateDlg;<br />
m_dCreateDlg->DoModal();
this is this.
