CMapStringToString lookup() qestion [solved]

[econy]

I use a CMapStringToString object to store some string key-value pairs, the string are read from a Unicode text file. a.text like the following: 4001 English //space is a TAB key space 4002 German 4003 Chinese 4004 Russia then I read the text file to a CString strLine, use str1 = strLine.Tokenize(TEXT("\t"),tokenPos); to get token; str2 = strLine.Tokenize(TEXT("\t"),tokenPos); I set breakpoint, I can read the token is right,i.e. str1 = 4001/4002/4003/4004; str2 = English/German/Chinese/Russia every loop. In the loop, I use : mStrMap.SetAt(str1,str2); and after loop; mStrMap.Lookup(_T("4001"),tstStr); mStrMap.Lookup(_T("4002"),tstStr); mStrMap.Lookup(_T("4003"),tstStr); mStrMap.Lookup(_T("4004"),tstStr); The weird thing is , 4002/4003/4004 key, I got right value: German/Chinese/Russia but for 4001, I got an empty string; I thought maybe it is oxFEFF (unicode BOM), so before the loop to readline circularly, I first read BOM so as to move the file pointer back. But still, for 4001, I got an empty string. Don't know why this happened.

You need to show the exact code. And please use <pre> tags around the code blocks so it is more readable thus:

mStrMap.Lookup(_T("4001"),tstStr);
mStrMap.Lookup(_T("4002"),tstStr);
mStrMap.Lookup(_T("4003"),tstStr);
mStrMap.Lookup(_T("4004"),tstStr);

You can automate that by selecting all the lines of code in the editor and using the code button at the top.

Sorry, it's my fault too. I read BOM, forgot to change the key string.
