[Resolved] Can someone help me with this line of code?

Code:

---

TCHAR filebuf[256];

_tprintf(_T("Directory = {%s}\n"), filebuf);

---

I wish to convert this code into a char type or a char(That is not printed onto the screen).

So basically:

Somechar=filebuf;

I've tried every way my brain can think of. I either get compiler errors, or i get weird HEX numbers on the screen (I'd say they are the memory addresses of the filebuf pointer). However, I can't get it working :( .

I'm trying to find out the directory that the program is in when it's running (App.Path in VB terms), then writing it into a file. This code is the only thing stopping me. The path comes up on the screen. But I can't convert into another data type from here.

It already is in char type.
What are you using to write to file? the fstream header? Or fopen//fwrite//fclose ?

I believe it's ofstream.

Here's basically my code:

Code:

---

ofstream myfile (destFile);
int lineCount;
myfile << "";
lineCount=0;
string newstr;

if (myfile.is_open())
        {
                lineCount++;
                myfile << newstr << endl;
                cout << "Line " << setw(4) << lineCount << ": " << newstr << endl;
        }
        else cout << "Unable to open file";
        }
                if (myfile.is_open())
        {
                myfile.close();
        }
}

---

Basically, I need the exe path to go into a variable, into a parameter though a function, then into into newstr. The parameter requires it to be of type char *, but I need it in a char * variable first.
Or in code terms:

Code:

---

char *file_path;
*file_path = (_T("Directory = {%s}\n"), filebuf);

---

So that it puts the path into the string instead of printing to the screen.

I get the following error when trying to do that code:

PHP Code:

---

error C2440: '=' : cannot convert from 'TCHAR *' to 'char' 


---

If you require the full code I will post it up, but I think I've answered your questions :).

When I tried to compile some code with the line

Code:

---

*file_path = (_T("Directory = {%s}\n"), filebuf);

---

it said _T() wasn't recognized. What headers are you including? It would just be better to post your entire code.

But here's how I'd do it.

Code:

---

char cFile[512];
DWORD dwFile;
GetModuleFileName(NULL,cFile,dwFile);
printf("Path: %s\n",cFile);

---

That will retrieve the full path of the current exe, including the filename.
E.G. D:\apps\file.exe

It'd be easy to write a function to retrieve just the directory from a full file path.

Okay, here it is!

Yep, I'm willing to try any way to get the path name into type char*. It needs to be passed into the doFiles function (Single \ stop it from working, so all directories need to have \\ separating the folders).

I tell you what, this is quite a learning curve.

Also I get this error when trying to run your code:

PHP Code:

---

Error    1    error C2664: 'GetModuleFileNameW' : cannot convert parameter 2 from 'char [512]' to 'LPWCH' 


---

Actually, forget it all!

I've figured it out.

I'm just having troubles with the escape character now.

Code:

---

char *TCHARTocharPath(TCHAR *theTCHAR)
{
        int theSize = (sizeof(filebuf));
        int i;
        int lastSlash;

        lastSlash=0;
        *theResult='\0';

        for (i= 0; i <= theSize-1; i++)
        {
       
                theResult[i] = Chr(theTCHAR[i]);

                if (theTCHAR[i]=='\0' || Chr(theTCHAR[i])=='\0')
                {
                        break;
                }
        }

        for (i= 0; i <= theSize-1; i++)
        {
                if (theResult[i]=='\\')
                {
                        theResult[i]=92;
                        i++;
                        theResult[i]=92;
                        i++;
                        theSize+=2;
                }

                if (theTCHAR[i]==92)
                {
                        lastSlash=i;
                }
        }
       
        if (sizeof(theResult)+1 > lastSlash)
        {
                theResult[lastSlash]='\0';
        }

        if (theResult[theSize] != '\0')
        {
                theResult[theSize+1] << '\0';
        }

        //cout << theResult;
       
        return theResult;

}

char Chr(int value)
{
char a;
a = value;
return a;
}

---

I want to make it so that every time there's a \ in theResult, I want another 1 inserted (Before or after doesn't matter) as long as their are 2 of them.

For some reason I can't get this to work! Have tried just using ascii and putting it in with '\'. Either way when i go to display this:

Code:

---

char *file_path;
file_path=TCHARTocharPath(filebuf);
cout << file_path << endl;

---

It comes up blank =S. Maybe there's a better way? It has to be left as a char type however.

Thanks for everyone's help =).

I'll post source code if someone asks.
