Yes, it works. Thanks Timo!

But why? When I type 'Inch', it draw in another place?

I do not publish any changes from now within two months.
I made a lot of changes and corrected a mountain of bugs:
Everyday I work with the program during many hours to find what is wrong.
For now it seems clean.

https://www.mediafire.com/file/w7bgnudn0pyrgpo/Cfe-Setup-Sources.exe/file is a link on the full source code.
and https://www.mediafire.com/file/9gd06wkttk35v7p/Cfe-Setup.exe/file is the link on the lat version.

Source code = Binaries

Play with it you will be very surprised if you think you where pretty... I test on me and did not recognized myself.

There is an other domain that I would like to include, it is the CNN seems not too complicated...

Telle me what is wrong or what could be improved, that would help me.

Graphics programming / Why GDIplus dont work?

Hello, I try to code gdi plus, and this no draw anything! And no errors..why?

Code: [Select]

#include <windows.h>
#include <fgdiplusflat.h>

#pragma comment (lib,"Gdiplus.lib")


VOID OnPaint(HDC hdc)
{
GpStatus g_ok;
Graphics graphics;
Pen pen;

TextOut(hdc, 0, 0, "Hello, Windows!", 15);

g_ok = GdipCreateFromHDC(hdc,&graphics);

if(g_ok != Ok)
{
WCHAR errCode[4];
wsprintfW(errCode,L"%d",g_ok);
MessageBoxW(0,errCode,L"GdipCreateFromHDC",MB_OK);
return;
}

g_ok = GdipCreatePen1(MakeARGB(255, 0, 0, 255),1.0,UnitInch,&pen);

if(g_ok != Ok)
{
WCHAR errCode[4];
wsprintfW(errCode,L"%d",g_ok);
MessageBoxW(0,errCode,L"GdipCreatePen1",MB_OK);
return;
}
g_ok = GdipDrawLine(graphics,pen, 20, 20, 200, 100);

Assembly discussions / Re: Initializing local variables

Hi Grincheux,

Code: [Select]

PUBLIC   ClearMem
No need of this statement as procedures are visible to the external modules by default.

Code: [Select]

xchg   rdx,rcx
You could remove this line. Redefining the procedure :

Code: [Select]

ClearMem  PROC   __dwNumberOfBytes:DWORD,__lpPointer:QWORD PARMAREA=4*QWORD

Don't need it, remove the include.


This a file for computing a crc on 64 bits.
I join them if they can help you.

Thank you, good thing. Will be test it.
But where I can get #include "crc64speed.h" ?

User contributions / Memory Leaks

« Last post by Grincheux on Yesterday at 07:28:30 am »

Small functions to help to detect memory leaks.
It uses VirtualAlloc and creates a database where you can see the result of VirtualAlloc and VirtualFree

Example:

Code: [Select]

#ifdef __MEMORY_LEAKS__
   _lpImageInfos = (LPIMAGEINFOS) MemoryLeaks_Alloc(__LINE__,"LoadImageFromFile",sizeof(IMAGEINFOS) + 1024) ;
#else
   _lpImageInfos = (LPIMAGEINFOS) VirtualAlloc(NULL,sizeof(IMAGEINFOS) + 1024,MEM_COMMIT|MEM_RESERVE,PAGE_READWRITE) ;
#endif
   if(_lpImageInfos)

and the result:

RecNo   Action   LineNumber   Function   MemorySize   Address   Result
1   VirtualAlloc   3250   CreateFilter   3991   A6F30000   1
84   VirtualFree   4584   Main_OnDestroy   0   A6F30000   1
2   VirtualAlloc   1425   LoadImageFromFile   26088   A6F50000   1
83   VirtualFree   1540   ImageFree   0   A6F50000   1
73   VirtualAlloc   3350   SaveDatas   32768   A6F60000   1
74   VirtualFree   3425   SaveDatas   0   A6F60000   1

If that can help you...

I've discovered http://www.pellesc.com can be made to redirect to https://forum.pellesc.de, if entered manually.

That doesn't solve anything -- it's only an observation.
