For your attention

Craig & Gatzoulis Attorneys at Law 101 Stark Street, Manchester, UK, M34 1SN Fax/phone: +44(0)871 239 4453 Re: Your consent is being requested Good day, This is my second email to you. I believe you did not receive my first email. I am compelled to send this email a second time. As a matter of urgency and necessity, I have to contact you in a manner that seems unethical. It is an issue of one of my client who lost his life in plane crash involving Alaska Airline's Flight 261, which crashed on January 31st, 2000. His wife and only daughter also died in the disaster. Before the demise of my client, he disclosed to me his account status, which amounted to Ten million five hundred thousand American dollars. He also handed over to me some vital copies of documents regarding this fund deposit in London. I was at the last burial rite on February, 5th, 2000 to pay my final respect to one of my prominent clients. There I made thorough inquiries about his relatives but could not find any, and also discovered no one really knows about his assets and particularly, the fund currently in a UK bank account. Since then, I have made successive attempts to get his next of kin or relative to come forth and claim this fund but to no avail. As the personal lawyer to my late client, I cannot in any way claim it unless I get third party assistance. Just two weeks ago, I received a routine notification from the finance house concerning this fund, and the officials of this firm issued a warning, stressing the urgency for the next-of-kin to come forward to claim this fund immediately. Otherwise, they will have it transferred to the State Treasury account as an unclaimed fund. MY REQUEST; Owing to the fact that his daughter whom should have stood a better chance of claiming this fund, also perished in that fatal air crash, I want you to stand in as the next-of-kin to my late client. Like I earlier asserted, I have in my possession the necessary documents that will enable me to place you in, as the right beneficiary to my late client's fund in this firm. I also wish to state that it is not compulsory that you must be a blood relative of my client for you be a beneficiary. Everything lies with me. It is whomever I present to the Probate and bank as the next-of-kin that the bank will recognize as the beneficiary. As I am not sure of your consent, I would prefer that we maintain correspondence by email for the time being. It is necessary that I remind you that trust and transparency must be our watchword in the course of this transaction. I will discuss with you in details regarding the sharing of the fund when I receive your response. For confidentiality purpose, I advise that you do not discuss this with anyone. If there is any aspect that is not clear to you, please feel very free ask me. Thanks. Michael NB: If you would need me to call you, please include in your response, a phone number through which I can speak with you Notice: This message is intended only for the use of the individual or entity to which it is addressed and contains information that is privileged, confidential and exempt from disclosure pursuant to the work-product doctrine.

Win32 GrMouseWarp
by richard＠dogcreek.ca 03 Apr '09

03 Apr '09

There is a problem with GrMouseWarp in Windows. The Windows function "SetCursorPos" sets the mouse cursor to the window coordinates but GRX, the screen context resides in the client area of the window and the GRX mouse cursor and the Windows mouse cursor are unsynchronized. The Windows function "ClientToScreen" will synchronize the the GRX and Windows mouse cursors. Below is a replacement GrMouseWarp function that is found in "grev_w32.c" void GrMouseWarp(int x, int y) { POINT point; MOUINFO->xpos = imax(MOUINFO->xmin, imin(MOUINFO->xmax, x)); MOUINFO->ypos = imax(MOUINFO->ymin, imin(MOUINFO->ymax, y)); GrMouseUpdateCursor(); point.x = MOUINFO->xpos; point.y = MOUINFO->ypos; ClientToScreen(hGRXWnd, &point); SetCursorPos(point.x, point.y); } This works correctly when GRX is in a window and also when GRX is full screen.

GRX and OS X
by Tom Martin 11 Mar '09

11 Mar '09

I'm trying to get GRX to compile on OS X. I'm not having much luck, but I've seen some other threads where Maurice Lombardi has asked for the symbols dumped by GCC before compiling. I've uploaded these: http://drop.io/darwinsymboldefs/asset/a1p1-defs (download them by clicking on a1p1.defs there). I'm not subscribed to the mailing list so please Cc me on any replies. I would very much appreciate any help though. Best regards, Tom Martin

Race condition in vdrivers/vd_win32.c in 8 bpp modes
by Peter Schauer 12 Dec '08

12 Dec '08

vdrivers/vd_win32.c has a race condition with the loadcolor SetDIBColorTable function call, which happens sometimes on fast multiprocessor machines. If the WndThread is currently executing its BitBlt during WM_PAINT processing and the GRX user thread is calling GrAllocColor, the SetDIBColorTable function call fails, as the DC is locked by the BitBlt. This results in the color not being set, which could also happen during the initial setting of the VGA colors in _GrResetColors. This affects only 8 bpp modes, as loadcolor is not called in 32 bpp modes. I can reproduce this problem on a modern dual core Vista system, and on a dual core Linux system running Wine. It happens less often on a modern dual core XP system, but it happens. My proposed fix delays the SetDIBColorTable call and moves it to the WM_PAINT processing, making it synchronous with the BitBlt call. Hope that helps, *** vdrivers/vd_win32.c- Mon Nov 24 19:32:14 2008 --- vdrivers/vd_win32.c Mon Nov 24 21:25:56 2008 *************** *** 101,106 **** --- 101,113 ---- static volatile int isWindowThreadRunning = 0; static volatile int isMainWaitingTermination = 0; + struct _GR_modifiedColors { + int modified; + RGBQUAD color; + }; + static struct _GR_modifiedColors modifiedColors[256]; + static volatile int isColorModified = 0; + static DWORD WINAPI WndThread(void *param); static LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam); *************** *** 112,119 **** color.rgbGreen = g; color.rgbRed = r; color.rgbReserved = 0; !

Error "Can't find suitable video mode" on framebuffer only build
by Whitney, Meiling G 15 Oct '08

15 Oct '08

I finally had the grx work with both svgalib/framebuffer and x11 builds on SUSE 11.0. But I got the video mode not find error for framebuffer only build. The project compiled successfully but failed on runtime during setting to graphic mode. I used GrCurrentVideoDriver() to check the video mode and got total 80 video modes returned. Except the default that gives me valid width and height(80, 25), all the other ones returned (0,0). What should I do now?

How to exit demogrx
by Whitney, Meiling G 14 Oct '08

14 Oct '08

Maurice, Many thanks for the help. The way to exit console is the combination key "Alt + F7". I am sorry for asking this simple question that is not related to GRX. Now I got some experience and had GRX work for both Linux console (with svgalib and framebuffer) and X11. Eventually we'll need GRX for embedded compiler Nios2Linux (or UCLinux). I am wondering if the Linux console with framebuffer only would reduce some overhead from using svgalib. (Any idea on how to use the combination will help.) Now I successfully build GRX with framebuffer but run into "Can't find suitable video mode" error when running the demo. I just posted the question with another thread yesterday. Any help would be greatly appreciated. Meiling This message (including any attachments) contains confidential and/or proprietary information intended only for the addressee.

How to exit demogrx
by Whitney, Meiling G 09 Oct '08

09 Oct '08

Hi, I am new to Linux as well as graphics driver/lib. I compiled the test program with no problem in grx with default config settings against Linux console. But I don't know how to exit the demogrx program after I run it. I can't see the mouse or any other sign that would lead me out of the black console screen with the sample grx test window. Any help would be appreciated. Regards, Meiling This message (including any attachments) contains confidential and/or proprietary information intended only for the addressee.
