how to find a file in one folder
-
hi, as the titel.The user will input the name of the file and the folder through EDITBOX. m_name is the Variable ,in CStrig. Here is mz code void CFilefindDlg::OnButton1() { // TODO: Add your control notification handler code here HANDLE handle; WIN32_FIND_DATA fd; handle = FindFirstFile(m_name, &fd); if (handle != INVALID_HANDLE_VALUE) AfxMessageBox("Find this folder."); else AfxMessageBox("Could not find folder."); } I dont how to use funktion FindFirstFile().If i write in char path[256]="C:\\guo\\1.txt"; handle = FindFirstFile(path, &fd); It is right. But the name of the file should be decided by the user. How can i do it ?:doh::doh::doh: Thanks!

If I'm understanding your situation correctly, your dialog box has an edit control and a button to initiate a "file search". You created a member variable for the edit control in the dialog class. This member variable is of type CString? If so, the string variable will not get updated until the data exchange routines run. Instead, you want access to the edit control directly so create a variable for the edit of type CEdit. If your using VC++ 6.0, in the ClassWizard, for the dialog class, under the member variables tab, select your edit control, click "Add Variable...", for "Category:" choose "control" and then select CEdit for the "Variable Type:". This way you can do the following with your code snippet... void CFilefindDlg::OnButton1() { // TODO: Add your control notification handler code here HANDLE handle=NULL; WIN32_FIND_DATA fd={0}; CString sFile=""; m_editName.GetWindowText(sFile); handle = FindFirstFile(sFile, &fd); if (handle != INVALID_HANDLE_VALUE) { AfxMessageBox("Find this folder."); } else { AfxMessageBox("Could not find folder."); } }

I think you need to
CString::Insertbecuase you need a string(path) and need to a file name
