I'm trying to get a couple of the Lead dialogs to work. I copied the code from your documentation for one and it gives me a -1093 error after DoModal. The l_error.h file doesn't have a -1093 error in it.

Here's the code:

LDialogImageEffect dlg;

LDialogImageEffect::Initialize(0);

dlg.SetBitmap((LBitmapBase*)pLeadBitmap);

GAUSSIANBLURDLGPARAMS parms;

memset (&parms,0,sizeof(GAUSSIANBLURDLGPARAMS));

parms.uStructSize = sizeof(GAUSSIANBLURDLGPARAMS);

result = dlg.EnableCallBack(FALSE);

result = dlg.EnablePreview(TRUE);

result = dlg.EnableToolbar(TRUE);

result = dlg.SetGaussianBlurParams(&parms);

result = dlg.DoModalGaussianBlur(pView->m_hWnd);

//Get Info

result = dlg.GetGaussianBlurParams(&parms, sizeof(GAUSSIANBLURDLGPARAMS));

result = LDialogImageEffect::Free();

This error means 'LTDLGIMGEFX.DLL
is not loaded'. Did you load this DLL using the LoadLibraries function using the LT_DLGIMGEFX flag?

The file I have is named LTDlgImgEFX14n.dll

I'm loading it with:

nRet = LBase::LoadLibraries (LT_DLGIMGEFX);

The error code is "1".

After a bunch of inti code, I call the L_DlgOpen method to bring up the Open dialog to load a graphic file.

nRet = L_DlgOpen( pView->m_hWnd,&OpenFileName,&FOParm );

The error code with this call is " -152", which is not defined in the Errors.h or the Return Codes in the LEAD documentation for the Class Library.

Here's all of the code:

L_INT nRet;

nRet = LBase::LoadLibraries (LT_DLGIMGEFX);

static BITMAPHANDLE Bitmap;

static OPENDLGPARAMS FOParm;

static SAVEDLGPARAMS FSParm;

static FILEINFO foFileInfo;

HWND hWndChild = NULL;

L_BOOL fLoadInfo;

L_BOOL fAutoProcess = TRUE;

static OPENFILENAME OpenFileName;

static L_BOOL bEnablePreview=TRUE;

memset(&FOParm, 0, sizeof(OPENDLGPARAMS));

memset(&OpenFileName, 0, sizeof(OPENFILENAME));

FOParm.uStructSize = sizeof(OPENDLGPARAMS);

FOParm.bShowLoadOptions = FALSE;

FOParm.bPreviewEnabled = TRUE;

FOParm.uDlgFlags = (DLG_OPEN_ENABLESIZING|

DLG_OPEN_SHOW_PREVIEW|

DLG_OPEN_USEFILESTAMP |

DLG_OPEN_SHOW_PROGRESSIVE |

DLG_OPEN_SHOW_MULTIPAGE |

DLG_OPEN_SHOW_DELPAGE |

DLG_OPEN_SHOW_LOADROTATED |

DLG_OPEN_SHOW_LOADCOMPRESSED |

DLG_OPEN_SHOW_LOADOPTIONS |

DLG_OPEN_SHOW_FILEINFO |

DLG_OPEN_SHOW_PDFOPTIONS |

DLG_OPEN_SHOW_RASTEROPTIONS |

DLG_OPEN_SHOW_VECTOROPTIONS |

DLG_OPEN_VIEWTOTALPAGES |

DLG_OPEN_LOADBITMAP);

fAutoProcess = FALSE;

DWORD nOpenIndex;

OpenFileName.lStructSize = sizeof(OPENFILENAME);

OpenFileName.hwndOwner = pView->m_hWnd;

OpenFileName.nFilterIndex = nOpenIndex;

OpenFileName.lpstrTitle = TEXT("Open a File");

//fLoadInfo = LBase::EnableLoadInfo(TRUE);

nRet = L_DlgOpen( pView->m_hWnd,&OpenFileName,&FOParm );

This
error means ERROR_DLG_NOTINITIATED, You did not initialize the dialogs. This error is defined in the Lterr.h file.

You should initialize the Dialogs before using them, use the L_DlgInit function.
