I am using LeadTools v13 with the C++ classlib. I would like to
allow the user to select multiple images which are then loades into an
imagelist. I have no problem one image at a time but cannot
enable multi-select.
1. Does the classlib in v13 support muti-select on the file open?
2. If so, how?
3. If not, does v14?
Thanks

Hello,
This feature is supported in LEADTOOLS v13 and LEADTOOLS v14.5.
First of all, In the OPENFILENAME structure, you should pass the OFN_ALLOWMULTISELECT parameter to the Flags member of the OPENFILENAME structure to enable Multiselect feature in the Fileopen dialog, and then call the LDialog::SetOpenFileName method to set the OPENFILENAME structure( LDialogFile::GetOpenFileNameParams in v14.5).
Thanks,

I tried that but I keep getting a return code of -10 from DoModalFileOpen when I select more
then one image from a folder. Here
is a section of the code:
void CImageBar::OnFileImgImport()
{
LBitmapBase mBitmap;
FILEINFO FileInfo;
FILEOPENPARM FOParm ;
OPENFILENAME OpenFileName;
L_UINT uFlags =
(DLG_FO_MULTIPAGE | DLG_FO_FILEINFO | DLG_FO_SHOWPREVIEW);
int rc;
L_CHAR szFileName[_MAX_PATH];
L_CHAR szPathName[_MAX_PATH];
szFileName[0] = 0;
szPathName[0] = 0;
FileInfo.Flags = 0;
mBitmap.Dialog()->GetFileOpenParameters(&FOParm) ;
FOParm.pBitmap = mBitmap.GetHandle();
FOParm.pFileInfo = &FileInfo;
FOParm.bPreviewEnabled = TRUE;
FOParm.pThumbnail = NULL;
FOParm.bLoadRotated = FALSE ;
FOParm.bLoadCompressed = FALSE;
mBitmap.Dialog()->SetFileOpenParameters(&FOParm);
::ZeroMemory(&OpenFileName, sizeof(OPENFILENAME));
OpenFileName.lStructSize = sizeof(OPENFILENAME);
OpenFileName.lpstrFilter = szOpenFileFilter;
OpenFileName.nFilterIndex = 1;
OpenFileName.lpstrFile = szFileName;
OpenFileName.nMaxFile = _MAX_PATH;
OpenFileName.lpstrFileTitle = FOParm.szFileName;
OpenFileName.nMaxFileTitle = MAX_PATH;
OpenFileName.lpstrInitialDir = m_saveImportDir;
OpenFileName.lpstrTitle = "Import an Image";
OpenFileName.lpstrDefExt = NULL;
OpenFileName.Flags
= OFN_ALLOWMULTISELECT;
mBitmap.Dialog()->SetOpenFileName(&OpenFileName);
if ((rc = mBitmap.Dialog()->DoModalFileOpen(m_hWnd,uFlags)) == SUCCESS) {

Hello,
To resolve the problem try to pass NULL instead &FileInfo FOParm.pFileInfo parameter in your code. The code as follows:
+---------------------------------+
...
mBitmap.Dialog()->GetFileOpenParameters(&FOParm);
FOParm.pBitmap = mBitmap.GetHandle();
FOParm.pFileInfo = NULL;//&FileInfo;
FOParm.bPreviewEnabled = TRUE;
...
+---------------------------------+
