The code I have at present just isn't doing what I think it should be doing, and I'm getting the complete list of possible save formats.     try     }         LDialogFile dlg(pBitmap);         dlg.Initialize(0);         SAVEDLGPARAMS fsp;         memset ( &fsp, 0, sizeof ( SAVEDLGPARAMS ) ) ;         dlg.GetSaveParams(&fsp, sizeof(SAVEDLGPARAMS));         fsp.nPageNumber = 1;         fsp.uSaveMulti  = FALSE;         // Keep file types to a bare minimum so user can understand!         FILESAVEFORMAT fsf[5];         fsf[0].nFormat = DLG_FF_SAVE_JPEG;         fsf[1].nFormat = DLG_FF_SAVE_PNG;         fsf[2].nFormat = DLG_FF_SAVE_TIFF;         fsf[3].nFormat = DLG_FF_SAVE_BMP;         fsf[4].nFormat = DLG_FF_SAVE_PCX;             fsp.uFileFormatsCount = 5;         fsp.pFileFormats = fsf;         dlg.SetSaveParams(&fsp);         .........     } Any help would be most welcome. thanks Jeremy    Report

NOTE: If you are attaching a project or file to the forums... 1.) Zip the file(s) up. 2.) Make sure it is less than 5 MB.  If it is larger, please send an email to support@leadtools.com and we'll send you FTP instructions. 3.) Remove ANY AND ALL unlock codes and LEADTOOLS DLLs. 4.) Do not click the preview button, the attachment will not show up when you post it.   If you do not wish to post your file(s) on the forum since they are publically viewable, please send an email to support@leadtools.com and make sure that you include a link to this forum post.

If you still have the problem in a small sample project, I'll gladly take a look at it. Greg Ross LEADTOOLS Technical Support    Report

Got a small app working the way I wanted it to, and it turns out I wasn't setting the size of the SAVEDLGPARAMS structure before calling SetSaveParams(LPSAVEDLGPARAMS). Also, several of my calls into LeadTools methods that return error codes were not surrounded by a try-catch block so I was missing the errors!! Jeremy    Report
