How to store large amounts of data to the variable CStringList-CodePudding

 if (PathFileExists (PDLG - & gt; Str_upLoadFilePath)) 
{
CFile file_load; 
If (file_load. Open (PDLG - & gt; Str_upLoadFilePath, CFile: : modeRead)) 
{
DWORD file_len=(DWORD) file_load. GetLength (); 
PDLG - & gt; I_upLoadMaxNum=file_len/512; 
If (PDLG - & gt; I_upLoadMaxNum * 512 & lt; File_len) 
{
PDLG - & gt; I_upLoadMaxNum + +; 
} 
Char carr_fileData [512]. 

UINT u_readLen; 
While (TRUE) 
{
U_readLen=file_load. Read (carr_fileData, 512); 
Cstrings str_temp str_data; 
For (UINT I=0; i {
Str_temp. The Format (_T (" % 02 x "), (BYTE) carr_fileData [I]); 
Str_data +=str_temp; 
} 
PDLG - & gt; List_strUpFile - & gt; AddTail (str_data); 
If (u_readLen & lt; 512) 
{
break; 
} 
} 
} 
File_load. Close (); 
}

Read the file is in the thread, list_strUpFile is a member of the dialog box class
CStringList * list_strUpFile;//declare
List_strUpFile=new CStringList;//initialize

The POSITION pos=list_strUpFile - & gt; FindIndex (n);//read the data
Str_data=https://bbs.csdn.net/topics/list_strUpFile-> GetAt (pos);

Fetch the data, when n is larger than 560 or so would be an error

Excuse me, how can store more data CStringList?

My goal is to read multiple files, file size from 1 byte - 5 m, want to put the files into 512 bytes sent a pack of, what better way to read these files, please?

Stack over, stop and take a look at the call Stack, the existence of the invocation of the recursive form?

Loop read your data file data, read 512 bytes of data at a time, and then send?

Yes, after will use data in a file so be saved

CodePudding user response:

Stack overflow is stack memory is used up, usually is to check the status of recursive
