Reading the name of all image files in a folder

[siva_321]

Hi I am using the following code to browse throgh the folders.


void CBitmapAppUi::BrowseUsingAknSelectionDlg(const TFileName& aPath)
{
filename.Append(PathInfo::PhoneMemoryRootPath());


_LIT(KDialogTitle, "Browse files");
TBool ret = CAknFileSelectionDialog::RunDlgLD(filename,PathInfo::PhoneMemoryRootPath(),KDialogTitle,NULL);

// "ret" is true, if user has selected a file
if( ret)
{
_LIT(KQueryStr, "Open file");
TBool retval=CEikonEnv::QueryWinL(KQueryStr,filename);
if(retval)
Convert(filename);//Function to convert selctd file into mbm format to draw it in screen

}
else
{
CEikonEnv::Static()->InfoWinL(_L("Select Image"),_L(""));
}
}



If the user selects a image in a folder(EX:C:\Data\Images\Pictures\winter.jpg),I want to read the name of all image files in the same folder and want to open it one by one(similar to slideshow).

How to do that?Please help me.
Thanks.

Hello,
for getting file list name you could use:

TInt GetFilesFromFolderL(const TDesC& aFolder,
		CDesCArray* aArray, TUint aEntrySortKey)
	{
	CDir* File_list = NULL;

	while (iFilesArray->Count()> 0)
		{
		iFilesArray->Delete(0);
		iFilesArray->Compress();
		}
	TInt err = 0;
	err=iFs.GetDir(aFolder, KEntryAttNormal, ESortByName,
			File_list);
	if(err!=KErrNone)
		{
		if(File_list)
			{
			delete File_list;
			File_list = NULL;
			}
		return err;
		}
	if (File_list)
		{
		File_list->Sort(aEntrySortKey);//ESortByName|EDescending

		for (TInt i = File_list->Count() - 1; i >= 0; i = i - 1)
			{
			if (!File_list->Count() || (*File_list)[i].IsSystem()
					|| (*File_list)[i].IsHidden() || (*File_list)[i].IsDir())
				{
				// ignore System & Hidden Files & folders
				}
			else
				{
				aArray->AppendL((*File_list)[i].iName);
				}
			}
		}

	delete File_list;
	File_list = NULL;
	return err;
	}

calling:

GetFilesFromFolderL(KFolderName, iFilesArray, ESortByName);

While you have it you can check extensions of the files and remove thoes which are not images.


ps.
for selecting image from device you could use MGFetch:

CDesCArray * iArray;
iArray = new (ELeave) CDesCArrayFlat(1);
if (MGFetch::RunL(*iArray, EAnyMediaFile, EFalse))
	{
    TFileName fileName;
    fileName.Copy((*iArray)[0]);
if(iArray)
{
delete iArray;
iArray=NULL;
}

good luck

Hi Nuker,

Before calling ur GetFilesFromFolderL(KFolderName, iFilesArray, ESortByName);
user have to select to folder.

How to allow the user to select the folder?//sample code

Hello,
check SDK and search for RFs GetDir

err=iFs.GetDir(aFolder, KEntryAttNormal, ESortByName,
			File_list);

from sdk:

/**
@publishedAll
@released

File/directory attribute: a directory without the hidden or system attribute.
*/
const TUint KEntryAttDir=0x0010;

changing

KEntryAttNormal

you can select what do you want to display.
You could start with c:\\ drive and display its folders for example in listbox and if user select any of its items just refresh list

(( *FilesArray ) [ iListBox->View()->CurrentItemIndex()])

appended to "c:\\" and display thoes path folders

good luck
