So I want a nice cute MFC dialog to pop up in the middle of my game. Here is the code that crashes (or at least pops up a debug assertion failure) sFilename = g_CurrentOptions.sFileLocation; fileDlg = new CFileDialog(TRUE, NULL, sFilename, OFN_HIDEREADONLY|OFN_FILEMUSTEXIST|OFN_PATHMUSTEXIST, NULL,NULL); and then I run fileDlg->DoModal() if I comment out everything icluding DoModal() and just leave those top 2 lines it still gives me the assertion failure (which leads to a crash later if I ignore it) and just to be sure I entered a vaild filename instead of sFilename and that still didn''t fix the problem. Aslo if I comment out sFilename = g_CurrentOptions.sFileLocation (the reg key for the file name) it still doest work... any clues? has this happened to any of you?

Your first reaction may be: "why the heck did this guy just reply to himself" It isn't because I have a spit personality disorder... it's just that i wanted to move this post back up from the depths of the stack so people would look at it.... i am SOOOOOoooo close to finishing this project only to get shot down by this at the VERY END!!!... ok here is some more info that may help you solve my problem:

i didn't start the project with MFC included (I dindt think i would need it)... turns out i needed to open a file using a dialog box... the ONLY way i could find to do this was to use CFileDialog (woo hoo looks like i get to include "afxdlgs.h" now huh). I took out all of my includes to "windows.h" "commdlg.h" etc. and put in the same basic libraries you use when you start a project using MFC. I can get the CFileDialog box to work in other applications that i STARTED by using MFC but i can't get it to work in this one since. i am assuming now because there is somthing i cant see going on behind the scene when you start a project using MFC (i checked the settings and check all the included .dll and .lib NOTHING i can see is different tho). like i said earlier... it compiles fine but gives me that stupid assertion failed (its not a user assertion i can tell you cuz i dont use em) when i actually click the "browse" function. if i ignore the assertion it actually lets me into the dialog box, but then the program crasehes if i go back in (crash = big major core dump of the ENTIRE 23 megs... i can only crash my computer 5 times before my __asm wont give me a pointer to the stack OOM... hehe i guess i need more memory to run my program.... OR i could just FIX THIS!!!) Help me Please!!! ok i will get off my knees now... but please help if you can

/************************This just in!!!
_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()
{ ASSERT(afxCurrentResourceHandle != NULL);
return afxCurrentResourceHandle; }

that is the windows code (duh hit debug brett... thats what VS is for *smack*) in "afxdlgs.h" (the inline part) that puts out the ASSERT... here are the options I am looking at now...
1) is this caused because i sent NULL in for cWnd param (the last one) WHY? because it DEFAULTS to NULL... can i get and send in a parameter there... (i have a handle to HWND but dont know the proper conversion... do i need to getDC or something?)
2)is it because the this pointer in the CFontDialog doesnt function? ... i think when i compile for release it will ignore (as will I)this assertion then...

So i guess my question is can i ignore it??? will this cause bad repurcussions?

Is there a particular reason you cant use the win32 OPENFILENAME and GetOpenFileName() instead of using MFC?
