QFtp : Uploading a directory

[smshamim]

Hi all,

Here is my problem:

Purpose:- Upload a directory from local host to remote machine (remote ftp server)

Qt Class in use:- QFtp Class

Problem:-

Source code given below, works fine if I put QmessageBox after line:

ftp->mkdir(directoryName);

Otherwise I get the error-

Changing directory failed:
Failed to change directory.

Source Code:-

uploadDirectory(QDir dir){
 
    QString absPath=dir.absPath();  
 
    QString directoryName=absPath.section('/',-1); 
    dir.setSorting(QDir::DirsFirst);  
    const QFileInfoList *localFileInfoList = dir.entryInfoList();    
 
   QFileInfoListIterator fileIterator(*localFileInfoList );
   int count=localFileInfoList->count();   
 
    QFileInfo* file;
    int mkdirFlag =1;
 
    for(int temp=0;temp<count;temp++) {
 
	file=fileIterator.current();
	if(mkdirFlag){
 
	    ftp->rawCommand( "PWD" );	    
	    ftp->mkdir(directoryName);
	    mkdirFlag=0;    
	    currentDir->cd(directoryName);
	    QString ftpString=ftpDir+QString("/")+directoryName;
	     ftp->cd(ftpString);
 
	}	
 
	if(file->isDir() && file->fileName()!="." && file->fileName()!=".."){
	uploadDirectory(QDir(currentDir->absPath()+QString("/")+QString(file->fileName())));
 
	}	
	if(!file->isDir())
	    uploadFile(currentDir->absPath()+QString("/")+file->fileName());
 
	++fileIterator;	
    }
    ftp->cd("..");  
 
    currentDir->cdUp();    
}

uploadDirectory(QDir dir){
    
    QString absPath=dir.absPath();  
    
    QString directoryName=absPath.section('/',-1); 
    dir.setSorting(QDir::DirsFirst);  
    const QFileInfoList *localFileInfoList = dir.entryInfoList();    
   
   QFileInfoListIterator fileIterator(*localFileInfoList );
   int count=localFileInfoList->count();   

    QFileInfo* file;
    int mkdirFlag =1;
    
    for(int temp=0;temp<count;temp++) {
	
	file=fileIterator.current();
	if(mkdirFlag){
	    
	    ftp->rawCommand( "PWD" );	    
	    ftp->mkdir(directoryName);
	    mkdirFlag=0;    
	    currentDir->cd(directoryName);
	    QString ftpString=ftpDir+QString("/")+directoryName;
	     ftp->cd(ftpString);
	
	}	

	if(file->isDir() && file->fileName()!="." && file->fileName()!=".."){
	uploadDirectory(QDir(currentDir->absPath()+QString("/")+QString(file->fileName())));
	    
	}	
	if(!file->isDir())
	    uploadFile(currentDir->absPath()+QString("/")+file->fileName());
	
	++fileIterator;	
    }
    ftp->cd("..");  
       
    currentDir->cdUp();    
}

Description:-

ftp:-denotes the remote ftp(Class QFtp)
currentDir:-denotes the current local directory(QDir)
ftpDir:-denotes current remote file path (QString)

Note: - we get this value by sending PWD command( ftp->rawCommand( "PWD") ) in the command reply function we set this value in ftpDir

directoryName:- if dir is “home/username/folder1” then directoryName gives folder1
uploadFile() function uploads the given file

Observation:-

It takes time to complete the function like get, put, mkdir, cd etc. and these functions are nonblocking. Program doesn’t block here. Just take an example if I call ‘mkdir’ (ftp->mkdir()) then program doesn’t wait for completion of this function. It goes to next line and performs (ftp->cd()) and I get the error.

How should I resolve this problem?

Thanks
