is there a way of interrupting dwg/dxf file loading?
is there a way of interrupting dwg/dxf file loading? drawing regen/redraw has such a possibility - 'regenabort()' callbacks, is there a similar mechanism for loading? diamantex # 24th may 2007, 10:04 am moderator join date: mar 2002 posts: 2,994 such possibility exists. while loading a file meterprogress() function is called from time to time. you can throw exception from this function. look at odamfcapp sample. if while loading a file you press escape key you get a warning message box from the following function (odamfcapp.cpp): code: /************************************************************************/ /* progress meter override */ /************************************************************************/ void codamfcappapp::meterprogress() { int noldpercent = m_npercent; m_npercent = int( ( double(m_nprogresspos++) / double(m_nprogresslimit)) * 100 ); if(noldpercent!=m_npercent) { cstring str; str.format(_t("%s %d"), m_msg, m_npercent); cmainframe* pwnd = (cmainframe*)getmainwnd(); pwnd->m_wndstatusbar.setpanetext(0, str); msg msg; while(::peekmessage(&msg, pwnd->m_hwnd, wm_keyup, wm_keyup, 1)) { bool bdup = false; if(msg.wparam == vk_escape && !bdup) { bdup = true; str.format(_t("are you sure you want to terminate\n%s ?"), m_msg); if(::afxmessagebox(str, mb_yesno|mb_iconquestion)==idyes) { throw userbreak(); } } } } } sergey slezkin sslezkin # 26th november 2007, 04:16 am registered user join date: sep 2003 posts: 131 throw userbreak() doesn't work in v2.4.2? hi, i just noticed that my code to abort file loading via throw userbreak() doesn't work anymore: the program throws an exception, but continues to load (while throwing exceptions...). just for testing i replaced userbreak() with oderror(enofilename), and this works: one error message, and the program stops. is this a problem related to the new version (2.4.2)? torsten torsten none ? | ? thread tools display modes linear mode search this thread rate this thread excellent good average bad terrible posting rules you may post new threads you may post replies you may post attachments you may edit your posts is on are on code is off html code is off forum jump user control panel private messages subscriptions who's online search forums forums home general topics news questions and remarks business issues industry commentary general software issues documentation issues future directions dwg libraries dwgdirect.net dwgdirect, c++ version dwgdirectx, activex version adtdirect/c3ddirect opendwg toolkit/viewkit dgn libraries dgndirect, c++ version (2.x+) dgndirect libraries (legacy 0.99xx) all times are gmt -7. the time now is 09:26 pmfff">. - - - copyright ?2000 - 2009, jelsoft enterprises ltd. copyright 1998-2008 open design alliance inc. such possibility exists. while loading a file meterprogress() function is called from time to time. you can throw exception from this function. look at odamfcapp sample. if while loading a file you press escape key you get a warning message box from the following function (odamfcapp.cpp): code: /************************************************************************/ /* progress meter override */ /************************************************************************/ void codamfcappapp::meterprogress() { int noldpercent = m_npercent; m_npercent = int( ( double(m_nprogresspos++) / double(m_nprogresslimit)) * 100 ); if(noldpercent!=m_npercent) { cstring str; str.format(_t("%s %d"), m_msg, m_npercent); cmainframe* pwnd = (cmainframe*)getmainwnd(); pwnd->m_wndstatusbar.setpanetext(0, str); msg msg; while(::peekmessage(&msg, pwnd->m_hwnd, wm_keyup, wm_keyup, 1)) { bool bdup = false; if(msg.wparam == vk_escape && !bdup) { bdup = true; str.format(_t("are you sure you want to terminate\n%s ?"), m_msg); if(::afxmessagebox(str, mb_yesno|mb_iconquestion)==idyes) { throw userbreak(); } } } } } sergey slezkin throw userbreak() doesn't work in v2.4.2? hi, i just noticed that my code to abort file loading via throw userbreak() doesn't work anymore: the program throws an exception, but continues to load (while throwing exceptions...). just for testing i replaced userbreak() with oderror(enofilename), and this works: one error message, and the program stops. is this a problem related to the new version (2.4.2)? torsten |
