Truncating Long File Names and Displaying an Ellipses


Full Text Search: The Key to Better Natural Language Queries for NoSQL in Node.js

I've seen a few articles that illustrate different techniques used in order to display an ellipses in the path. However, a simpler approach might be to use the new Shell path function: PathCompactPath.

BOOL PathCompactPath(
 HDC    hDC,
 LPTSTR lpszPath,
 UINT   dx
This function truncates a file path to fit within a given pixel width by replacing path components with ellipses.
  • Returns TRUE if successful, or FALSE otherwise.
Handle to the device context used for font metrics.
Address of the string to be modified.
Width, in pixels, that the string will be forced to fit within.

This function uses the font currently selected in hDC to calculate the width of the text. This function will not compact the path beyond the base file name preceded by ellipses.


#include <windows.h>
#include <iostream.h>
#include "Shlwapi.h"
HDC hdc;  /* display DC handle for current font metrics */ 

void main( void )

 // String path name 1.
 char buffer_1[] = "C:\\path1\\path2\\sample.txt";
 char *lpStr1;
 lpStr1 = buffer_1;
 // String path name 2.
 char buffer_2[] = "C:\\path1\\path2\\sample.txt";
 char *lpStr2;
 lpStr2 = buffer_2;
 // String path name 3.
 char buffer_3[] = "C:\\path1\\path2\\sample.txt";
 char *lpStr3;
 lpStr3 = buffer_3;

 // String path name 4.
 char buffer_4[] = "C:\\path1\\path2\\sample.txt";
 char *lpStr4;
 lpStr4 = buffer_4;
 // Variable to get the return from "PathCompactPath".
 int retval;	
 cout << "The un-truncated path is                " << lpStr1 << endl;

 retval = PathCompactPath(hdc,lpStr1,125);
 cout << "The truncated path at 125 pixels is :   " << lpStr1 << endl;

 retval = PathCompactPath(hdc,lpStr2,120);
 cout << "The truncated path at 120 pixels is :   " << lpStr2 << endl;

 retval = PathCompactPath(hdc,lpStr3,110);
 cout << "The truncated path at 110 pixels is :   " << lpStr3 << endl;

 retval = PathCompactPath(hdc,lpStr4,25);
 cout << "The truncated path at  25 pixels is :   " << lpStr4 << endl;

Output of Example

The un-truncated path is C:\path1\path2\sample.txt
The truncated path at 125 pixels is : C:\path1\...\sample.txt
The truncated path at 120 pixels is : C:\pat...\sample.txt
The truncated path at 110 pixels is : C:\p...\sample.txt
The truncated path at 25 pixels is : ...\sample.txt


  • long path tool

    Well, you can use Long Path Tool for such problems,it works good I will say.

  • Same can be done without shlwapi.dll

    Both DrawText and DrawTextEx support the DT_PATH_ELLIPSIS flag that allows truncation of a path to fit a specific width (or rectangle) in much the same was a described in this article.

  • am i missing something here ?

    IMO submitting KB or help articles from MSDN library isn't very helpfull - especially if you forget to mention that this function only works with ie 4 installed. (95/NT)
