hi !!

I am facing some problem retrieving size of a string from string Table. I am using FindResource() function to get handle for the resource.
I refered MSDN and get to know that String Table is stored as a block of memory of 16. Thus FindResource() will always give me address of that block. I am successfully retrieving handle to the block where the desired string is present.

The problem is I know at which place/ index the string is present in that block. But dont know how to retrieve it!! I want to get its size.

Can somebody plz help me on this!

Thx in advance

I am posting the code here

LPSTR GetErrorString(UINT uiStringId)
{
	int iRetVal=0;
	DWORD dwResSize=0;
	char temp[10];
	HRSRC hRes;

	//get the ID of the block
                DWORD nID = (uiStringId >> 4) + 1;

	//get the offset of the item within the block
	DWORD nitemID = uiStringId % 0x10;

	//get handle to the beginning of the block of 16 strings, where each string begins with its size
	hRes = FindResource(gl_hModule,MAKEINTRESOURCE(nID), RT_STRING); 

	
                //how to get the size of the string here, curretly giving the size of the block
               dwResSize=SizeofResource(gl_hModule,hRes);

    ....
...
..}

Why don't you try LoadString, that would be more comfortable for loading string resources.

Thx for the reply!

Actually I want the size of the string before calling LoadString().
This will allow me to allocate memory dynamically for that string.

It would be less troublesome to just allocate a (slightly) bigger-than-necessary buffer.

You should call the GetFullPathName() wherever you wish to show the full path of the file. If you are showing in a list box then use GetFullPathName when you are entering values in the list box

CFile file;
file.Open ("abc.txt",CFile::modeCreate | CFile::modeWrite );
DWORD buffLen=255;
char *filepath=new char[MAX_PATH];
file.Close ();
GetFullPathName("abc.txt",buffLen,filepath,NULL);
//AfxMessageBox(filepath); //filepath contains full path of the file

Here I created a file in the project directory and then using GetFullPathName I get the full path of the file in the string filepath
Does this solve your problem?

You can use DlgDirList(lpszCurDir, IDC_LIST1, 1, 0); it work with ListBox
int DlgDirList(HWND hDlg,LPTSTR lpPathSpec,int nIDListBox,int nIDStaticPath,UINT uFileType);
this parameter return a path in a control(static or...)

maybe it is some helpful to you

I see your code one question,
you need to get files with paths for example in drive c you have ten mp3 files in directory Music now you want to get these files in your list with path like this c:\Music\1.mp3,c:\Music\2.mp3 and... Right?

See this it work but you need to check for . and .. that its easy you can use from SetCurrentDirectory and check return value from this function

<code>
	CListBox *m_List=(CListBox*)GetDlgItem(IDC_LIST1);
	WIN32_FIND_DATA lp;
    HANDLE hFind = INVALID_HANDLE_VALUE;
	BOOL Bool=0;
	CString csFolderSelected;
	BROWSEINFO bi = {0};

bi.ulFlags = BIF_RETURNONLYFSDIRS ;     
LPITEMIDLIST pIt;     
if( (pIt = SHBrowseForFolder( &bi )))	 
{         
TCHAR tcPath[ MAX_PATH ];         
if( SHGetPathFromIDList( pIt, tcPath ))         
	csFolderSelected = tcPath;	 
} 

TCHAR lpszOldPath[MAX_PATH];         
::GetCurrentDirectory(MAX_PATH, lpszOldPath);
::SetCurrentDirectory(csFolderSelected);
	
   hFind = FindFirstFile(_T("*.*"), &lp);
   if(hFind)
	   Bool=1;

      while (Bool!= 0) 
      {
	   m_List->AddString(csFolderSelected+lp.cFileName);
   Bool=FindNextFile(hFind, &lp);
      }
      FindClose(hFind);
</code>
