[julianluthor]

how can i display Cluster1[0][n]in .dat file?Below is my code..

... 
for(int j=0;j<DataHeight;j++) 
{ 
for(int i=0;i<DataWidth;i++) 
{ 
Data[i][j]=(unsigned char)(((float)dataconv[j][i]-min)/(max-min)*255); 
if (Data[i][j]==170) 
{ 
Cluster1[0][n]=Data[i][j]; 
n++; 
} 
} 
}

int FilePtr = 0;

if (FileExists("filename.dat&quot)
FilePtr = FileOpen("filename.dat", fmOpenWrite);
else
FileCreate("filename.dat"

if (FilePtr > 0)
{
FileSeek(FilePtr, 0, 2);
FileWrite(FilePtr, &(Cluster1[0][n]), 1);
}

FileClose(FilePtr);

This will create the file if neccessary, or open it for writing, move to the end of it, add the byte, then close it.

there is error at this line :
FilePtr = FileOpen("filename.dat", fmOpenWrite);
that said call of nonfunction.

VCL is required, what version of C++ Builder are you using?
