The great god, help me, with the following code browsing and open the picture in the TXT file, how to placed into a n rows and eight columns of the array, trouble the great god help to add a piece of code, very grateful,

 cstrings filename.//open the file name string 
CFile file;//file object 
DWORD len.//used to save the file length 
CFileDialog DLG (TRUE, _T (" "), _T (" *. * "), OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, _T (" *. * | *. * | ")); 

DWORD g2Local_1=DLG. DoModal (); 

If (IDOK==g2Local_1) {

Filename. The Format (" % s ", DLG. GetPathName ()); 
} 
Else if (IDCANCEL==g2Local_1) {
return ; 
} 

//read the data 
File. The Open (filename, CFile: : modeReadWrite); 
Len=file. GetLength (); 
Char * pReadData=https://bbs.csdn.net/topics/new char (len);//allocate memory 
File. Read (pReadData, len);//of the data read the file 
File. The Close (); 

CodePudding user response:

1, each line according to the format to read better, such as the fscanf;
2, define a structure, the number of columns for each row;
3, define the structure dynamic array, save the data,

You read come in to do string segmentation, such as the data can be separated with Spaces
