Hello ..

Am retriving the application Stratup path like this:

C#

char buffer2[2048];
char buffer1[5120];
GetModuleFileName(NULL, buffer2, 5120);

In buffer2 am getting output as:
c:\Users\guruprasad\Desktop\gscanner\Debug\gscanner.exe

And,Actually i want to truncate gscanner.exe, so that my final output should be:
c:\Users\guruprasad\Desktop\gscanner\Debug\

Is the question asking how to remove "gscanner.exe" from the string?

Apparently... the usual reply in such cases: "What have you done so far?".

What have you tried?

Guru_C++ 4-Apr-12 2:02am

char* temp=buffer2;
int buff_len=strlen(temp);
for(int i=buff_len;i>0;i--)
{
temp[i]='\0';
if(i==43)
break;
}

With this code, if i rename the "gscanner.exe" to some other name.. Then it wont work..

There is API GetCurrentDirectory function[^]
And this will get you application startup directory:

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

#define BUFSIZE MAX_PATH

void _tmain()
{
   TCHAR Buffer[BUFSIZE];
   DWORD dwRet;

   dwRet = GetCurrentDirectory(BUFSIZE, Buffer);
   _tprintf(TEXT("Current directory: %s\n"), Buffer);

}

Solution 1

So what you want to do is:

- start at the end of the string and search backwards for the first backslash ('\') character

- if found, cut the string off exactly after that backslash

- if not found, do nothing

I don't give you the solution right away, but let you give a try at it. It is not really difficult and there is even a library routine for searching a string backwards for a specific character. You might go looking for it.

If you are not able to find the solution, which I doubt, I will give you some more hints.

Solution 2

C++

std::string ExtractDirectory( const std::string& path )
  {
  return path.substr( 0, path.find_last_of( '\\' ) +1 );
  }

int main()
{
char buffer2[2048];
char buffer1[5120];


GetModuleFileName(NULL, buffer2, 2048);

std::string dir = ExtractDirectory(std::string(buffer2));

}
