lost memory with images in xBrowse | Dear Reinaldo,
thanks very much for response, my problem with xBrowse is when I navigate between rows, if I change from an image to other (row to row) in the xBrowse, the memory go up until the system go full.

lost memory with images in xBrowse | Hi. I confirmed the problem. I wrote my own tests using a dbf/fpt/cdx table. It does the same.

lost memory with images in xBrowse | Mr. Rao;
It is always possible that the problem is not with xbrowse itself but rather the destroy mechanism being used to destroy the image.
Did you try Marcelo's example? It is a short-self-contained sample. The table only contains 4 images. Open the task manager and monitor the amount of memory being consumed by... |
lost memory with images in xBrowse | Hi.
Can anyone else, please, confirm this problem?
You may use the self-contained-reduced sample posted by Marcelo on this thread. If you prefer an even simpler sample using dbf/cdx, I will gladly write one.
Thank you,
Reinaldo. |

Grato ver la pregunta.
Saving an image, or anything else for that matter, is best done via pure SQL. To save images, I prefer to use a binary field instead of a memo field. Here is some actual code (a bit reduced):

Hi.
I think I hear crickets chirp. Not a good sign. I guess it is only the two of us saving images to a blob field that are later shown on an xbrowse? Or everyone else is living with the problem and simply accept that the application must be shutdown frequently? This is indeed a bug and an easy ... |

Best regards,

lost memory with images in xBrowse | Otto,
sorry, let me response your question, if you test the xbimg.prg sample (from sample folder) you will that this sample dosn't lost memory, then I think the problem is when the images come from DB.

lowbyte y calcxor | Necesito dos funciones que hagan lo siguiente:
1.- lowbyte:
Tiene que extraer los 8 bit (byte) de menor orden de un valor de 16 bits.
2.- calcxor:
Calcula el or exclusivo de un caracter.
No tengo ni idea de como hacerlo. |
lowbyte y calcxor | Puedes usar las funciones de FWH nAnd( nVal, 255 ) --> nLowByte
y para el CalcXor puedes usar la función nXor( Asc( caracter ), nVal2 ) --> nVal |
lowbyte y calcxor | Para el lowbyte creo que es más sencillo usar el operador módulo %
#define LowByte( x ) => ( x % 256 )

I'm not clear. What does the picture "XXXXXXX.XX" do to the display?

lpassword for numeric get | Dear James,
The picture 'XXXXXXX.XX" on the numeric get will replace the display value to "XXXXXXX.XX" instead of "9999999.99" or say a value of 12,999.45
This is a workaround since oGet:lPassword := .T. works only for char type.
This is selective scenario wherein some user must not see that field value. If I change... |

mac address | ops, my mistake <!-- s:-) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":-)" title="Smile" /><!-- s:-) -->
Then you should require it to xHB guys.
If I am not wrong, __chkstk stands for check stack, so you could safely create a dummy C function with such name
void _chkstk( void ) { } |
mac address | If I add that dummy function, GetNetCardID kills my app.
