MFC dialog-based demo

A 23-bit card number per line in txt.

The folder contains an image file named after the card number. (FPT or BMP file)

Request to traverse the folder, find the TXT card number corresponding to the image file, and copied out.

Written by VC6.0.

Too lazy, the code has been written before, direct copy is OK.


The code below is more commonly used and the changes are relatively large, please forget it.

voidCrenamefiledlg::onbutton1 () {//Button 1UpdateData (); CharBuf[max_path] = {0}; if(Select_any (BUF)) {M_pathname=buf;    UpdateData (FALSE); }    }voidCrenamefiledlg::onbutton2 () {//Button 2UpdateData (); //Generate an Open dialog boxCFileDialog *Lpszopenfile; Lpszopenfile=NewCFileDialog (TRUE,"Ccd.txt","", Ofn_filemustexist | Ofn_hidereadonly,"file Type (*.txt) |*.txt| All Files (*. *) |*.*|"); if(Lpszopenfile->domodal () = = IDOK)//If you click the dialog box to confirm the button{m_pathname2= Lpszopenfile->getpathname ();//get the path to the open fileSetWindowText (m_pathname2);//Show Path on window caption} updatedata (FALSE);}voidCrenamefiledlg::onbutton3 () {//Button 3UpdateData (); CharBuf[max_path] = {0}; if(Select_any (BUF)) {M_newfilepath=buf;    UpdateData (FALSE); }    }
voidCrenamefiledlg::onbutton2ok () {//Button 4strtemp="";    UpdateData (); if(m_pathname=="") {MessageBox ("Please select a path","Tips", MB_OK);return;    } h_filefile (M_pathname); ////Theapp.addtotxt (strtemp); AfxMessageBox ("The operation is complete! "); }

Traverse the folder and process the mold function.

CopyFile can only copy files, cannot copy the folder of the file, copy the code of the folder to be verified. (lazy, se years try)

Shfileopstruct SFO;
Sfo.hwnd = NULL;
Sfo.wfunc = fo_copy;
Sfo.pfrom = "C:\\my_docs1\0";
Sfo.pto = "C:\\my_docs2\0";
Sfo.fflags = Fof_silent |   fof_noconfirmation | Fof_noconfirmmkdir;
hr = SHFileOperation (&SFO);


I want to move a folder to another path, along with all the sub-files and subfolders under the folder! For example, f:\a\b is a folder that moves the entire B folder to d:\b. Hopefully it can be done by a function. If the function is MoveFolder (CString s,cstring D), C and D hold the path of the original folder and the destination folder respectively. Hope that the expert can give the complete code, if the parameters are not CString, can give the conversion code!! BOOL MoveFolder (CString strsrcpath, CString strdestpath) {Strsrcpath+ = _t (' /');//Note Here must add _t (' ""), do not write _t ("" ");Shfileopstruct si = {0}; Si.hwnd=:: GetDesktopWindow (); Si.wfunc=fo_copy; Si.pfrom=Strsrcpath; Si.pto=Strdestpath; Si.fflags= Fof_noconfirmation |Fof_noconfirmmkdir; return 0= = SHFileOperation (&si);}----------voidmycopydirectory (CString source, CString target) {createdirectory (target,null);//Create a destination folder//AfxMessageBox ("Create folder" +target); CFileFind Finder;          CString path; Path. Format ("%s/*.*", source);      AfxMessageBox (path); BOOLBworking =Finder.      FindFile (path);  while(bworking) {bworking=Finder.          FindNextFile (); AfxMessageBox (finder.          GetFileName ()); if(finder.) Isdirectory () &&!finder. Isdots ()) {//is a folder and the name does not contain. Or. Mycopydirectory (finder. GetFilePath (), target+"/"+finder. GetFileName ());//recursively Create folders + "/" +finder. GetFileName ()        }          Else{//is the file is copied directly//AfxMessageBox ("Copy File" +finder. GetFilePath ());//+finder. GetFileName ()CopyFile (finder. GetFilePath (), target+"/"+Finder.          GetFileName (), FALSE); }      }  }
