Some problems with CStatic

[DarkCount]

Hi, people!
I have some problems with reflection a text on CStatic. I read the first line of a text file with this function:

char * o_file(const char *filename)
{
		FILE *f=fopen(filename, "r");
		if (f!=0)
			{
			char ch;
			char *result=new char[];
			int i=0;
			fseek(f, 0, SEEK_SET);
		
	while (!feof(f) && ch != '\n' &&  ch != \r')
				{
				ch = fgetc(f);
				if ( ch != '\n' &&  ch != '\r' && !feof(f)) result[i]=ch;
				CSize sz = dc.GetTextExtent(result,strlen(result));
				i++;
				while (sz.cx>=rcstat.right-rcstat.left)
				{
					rcstat.right++;
				};
			fclose(f);
			return(result);
			}
		else 
		{
			fclose(f);
			AfxMessageBox("Error: File not found",MB_OK | MB_ICONSTOP,0);
			return NULL;
		};

};

It runs in this way:

	if (MyStatic!=NULL) MyStatic->Create(o_file(filename),WS_CHILD|WS_VISIBLE|SS_CENTER|SS_CENTERIMAGE,
		rcstat,this);

When program is running it sometimes works wrong. Why?

char *result=new char[];

I can't believe the compiler doesn't complain about this... You didn't specify how many chars you want to allocate.

dc.GetTextExtent

I have no idea what dc is? I don't see it declared anywhere, so I don't know what you're trying to do here.

You should use ifstream and string instead of those nasty old C functions like fopen(), fgets()... You can read the line from the file into a string in a few lines like this:

string strLine;
ifstream inFile( filename );

if ( inFile )
{
    inFile.getline( strLine );
}
else
{
    AfxMessageBox( "Error: File not found", MB_OK | MB_ICONSTOP, 0 );
}

Sorry, it's misprint (from other function...

    inFile.getline( strLine );

Unfortunately, this function unable to work Also it not works in the following aspect:

     std::getline(inFile, strLine);

Appear errors:

error C2039: 'getline' : is not a member of 'std'
error C2065: 'getline' : undeclared identifier

I use MS Visual C++ 6.0

 

[ArkM]

#include <iostream>

 

[DarkCount]

It not helps

 

[cpjust]

#include <fstream>  // For ifstream.
#include <string>   // For string.

using namespace std;  // Now you don't need std:: infront of things.

I don't know why, but it isn't working...
