If anyone has time maybe you could run this example below and let me know if this works on your system. It requires Directx 8.1 or greater, a pentium II processor to run. I've inluded the documentation in case anyones curious.
Thanks

it crashed for me. I couldn't find more info about error because of fullscreen.

great to see some error checking, but doesn't these return error too?

Code:

     ;set clip rectangle of Directdraw commands
     invoke  DDSetClipRectangles, screenrect, 1
     invoke  DDSetSoftClipRegion, 0, 0, SCREENWIDTH, SCREENHEIGHT
     invoke  DDSetDrawMode8, 0

     ;load in tile graphics
     invoke  DDCreatePlainFromBmp, TILESURFACE, "Tiles.bmp", DDVIDEOSURFACE, 0
     invoke  DDFillBack, 0
     invoke  DDFlipNV
     invoke  DDFillBack, 0

     ;DDCreateNewFont required for fonts not in the Windows font folder
     invoke  DDCreateNewFont, 0, FW_SEMIBOLD, 32, 64, 0, 0, "Black Chancery"

1. if i delete ttf, app still runs and look little weird...
2. if i delete bmp, app crashes. (that was probably the original reason - i tried without bmp)

madmatt: you must check error after EVERY procedure which can return error (including ReadFile, CloseFile, etc... ALL), and if you are in procedure, return the error. Also you then check error after every call of such procedure.

winXP, no idea about directX version.

i said: app crashes, if i delete BMP.

Problem is in DDCreatePlainFromBMP, exactly the one i stated before:

.

In your case, it's the call of first function (don't know it's name) in "DDCreatePlainFromBMP", which returns -1 if file doesn't exist. This goes unchecked. Following function calls are all unchecked too.

again: go through entire your sources, and check EVERY call there that can return error. I bet 96% of them do.

PS: Sorry to reverse your DLL.

No problem. Wow, figured all that out by reversing my dll, your dangerous! Laughing

Your not supposed to delete the bmp, does it work if you don't? also added a 15bit and 16bit version. I'm not able to test the 15bit version so let me know if this works. I'll take care of all the error checking in the next update, right now have other things to do.

Start ... Run ... dxdiag.exe

DirectX Version: DirectX 9.0c (4.09.0000.0904)

I hear that DirectX 10 will be exclusive to Vista (dunno why, though).

EDIT: I didn't test this because I didn't think you'd need testing on such a common machine as my P4/2.52 Ghz Win XP Home SP2 DirectX 9.0c cpu. (Tell me if I'm wrong, though!)

Didn't take a minute. I just looked in your .asm which function takes name of BMP as arg (DDCreatePlainFromBMP), looked in DLL at that function, didn't saw no CreateFile, so i looked into function called in it, and there it was. If CreateFile fails, -1 is returned, and it was unchecked by caller.

EDIT: yes, with BMP it works. But i keep seeing windows's "hourglass" cursor, too much cooperative mode?.

rugxulo: go ahead, the more reports the better.

vid: Look's like i forgot to make the cursor disapear. It uses exclusive mode which is full speed ahead, but also set the "allow_reboot" flag.

I'm working on V2.0 that will fix all of these problems, and more.

Other people will probably say "because it's new architecture omg!!!", but the real reason is of course that MS needs a selling point for Vista.

fodder: found this interesting bit of info from: www.firingsquad.com

Quote:

The one thing that Microsoft has done with Vista is incorporate a subsystem that will comply with DirectX 9.0 graphics hardware due to the population of users that still own DX9-compliant hardware. This subsystem will be named none other than DirectX 9.0L. So, in short, if you have DirectX 9 hardware, you will be using DirectX 9.0L as your API in Windows Vista.

DirectX 9L will support all the fancy eye candy effects Microsoft has integrated into Vista’s Aero Glass interface, so DX9 users will still get the 3D desktop and all its effects under DirectX 9.0L. According to Microsoft, it would be difficult to port DirectX 10 to older operating systems like Windows XP due to the new driver model.

pabloreda: Thanks. Only very old cards use 15-bit graphics now. 16-bit is the norm now.
