Hi, here is how I used std::mapmapVar; void Myfun1() { ... CString strTemp = "str1"; mapVar[strTemp] = myStructObj1; } void MyFun2() { map<CString, CMyStruct>::const_iterator itr; Cstring strTemp = "str1"; itr = mapVar.find(strTemp); .... } Sometimes it is working fine but sometimes it is not working.

Hello everyone, I am using std::map in my application. I am searching for CMyStruct based on the CString using find function. But sometimes find function is returning null iterator even when there is strcture obj with specified key. Can anyone help me in finding the solution?

hi, Try this one... Disable the button in OnInitDialog of your dialog class eg: GetDlgItem(UR_CLOSE_BUTTON_ID)->EnableWindow(FALSE); Enable that button in OnBnClickedOpen function void CSRFToolDlg::OnBnClickedOpen() { char* ReadFileName = "G:\\Work On\\CPP\\SRFTool\\text_file.txt" ; if(openFile.Open(ReadFileName, CFile::modeCreate | CFile::modeReadWrite)) { AfxMessageBox("File creates successfully", MB_OK) ; GetDlgItem(UR_CLOSE_BUTTON_ID)->EnableWindow(TRUE); } else { AfxMessageBox("Error in file opening", MB_OK) ; } } Again Disable the button in OnBtnClickedClose() void CSRFToolDlg::OnBnClickedClose() { openFile.Close() ; GetDlgItem(UR_CLOSE_BUTTON_ID)->EnableWindow(FALSE); } If you the control variable of Close button, the user that variable in place of GetDlgItem(UR_CLOSE_BUTTON_ID)
