You couldn't prompt how to make, that color of the text in one field depended on value of other field? From the text provided below a fragment clearly that I wanted to make, but this option works incorrectly (why - that irrespective of value of the field Korr the field Histogram is always displayed by dark blue color).
Code: Select all

Hi,
if you do it in this way, the color has the value at creation time.
Change it to a colorblock, which change the color at runtime.
Code: Select all
local bColorBlock:={|| iif(Rsp1k->Korr>0,{GRA_CLR_RED,nil},iif(Rsp1k->Korr=0,{GRA_CLR_BLACK,nil},{GRA_CLR_BLUE,nil})) }
DCBROWSECOL FIELD Rsp1k->Fakt HEADER 'Факт' WIDTH 1
DCBROWSECOL FIELD Rsp1k->Histogram HEADER 'Сходство' WIDTH 21 COLOR bColorBlock
DCBROWSECOL FIELD Rsp1k->Date HEADER 'Дата' WIDTH 10

Many thanks! You very much help me. I tried to make it in the different ways, but it turned out nothing, and your decision earned at once how it is necessary, as was conceived.
I like the tool more and more and it is pleasant what the result turns out. In general I on these tools simply enjoy development and I was very lucky that it still is necessary and for work (teaching and scientific work)

Also, it is more complex, but you can do similar things with DCGETs. But in this case, you need to be concerned about focus colors/out of focus colors and whether or not you use the COLORGETS DCGETOPTIONS clause.
We have used this extensively. The key is using codeblocks.
I have examples of how we do it.

No, I didn't reach yet before about what you speak but when I will reach - if I will not understand itself, I will surely ask. It is very good that there are sympathetic people, and it is even better that they not simply sympathetic, but professionals. I am very grateful to you and placed information on gratitude for your support in the section "About system" big system developed by me.
By the way, whether there is a possibility to display in DCBROWSECOL pseudo-graphic ASCII symbols, for example CHR (177) or CHR (219)? And that was necessary to display histograms a symbol "|".

Somebody couldn't prompt how to correct the mistake of execution arising in attempt of creation of a database:
Code: Select all
FUNCTION GenDbfDostMod()
********* Создать БД Dost_mod.dbf и ее индексные массивы
cFileName := "Dost_mod"
aStructure := { { "Type_model ", "С", 40, 0 }, ;
{ "Int_krit ", "С", 30, 0 }, ;
{ "Dost_ident ", "N", 19, 7 }, ;
{ "Dost_neident", "N", 19, 7 }, ;
{ "Dost_avr ", "N", 19, 7 }, ;
{ "Date ", "C", 10, 0 }, ;
{ "Time ", "C", 8, 0 } }
DbCreate( cFileName, aStructure, "DBFNTX" )
RETURN NIL
Thus the old checked CLIPPER-way works absolutely normally:
Code: Select all
****** Создаем файл структуры базы данных ****************
CREATE Struc
APPEND BLANK
REPLACE Field_name WITH "Type_model",;
Field_type WITH "C",;
Field_len WITH 40,;
Field_dec WITH 0
APPEND BLANK
REPLACE Field_name WITH "Int_krit",;
Field_type WITH "C",;
Field_len WITH 30,;
Field_dec WITH 0
APPEND BLANK
REPLACE Field_name WITH "Dost_ident",;
Field_type WITH "N",;
Field_len WITH 19,;
Field_dec WITH 7
APPEND BLANK
REPLACE Field_name WITH "Dost_neident",;
Field_type WITH "N",;
Field_len WITH 19,;
Field_dec WITH 7
APPEND BLANK
REPLACE Field_name WITH "Dost_avr",;
Field_type WITH "N",;
Field_len WITH 19,;
Field_dec WITH 7
APPEND BLANK
REPLACE Field_name WITH "Date",;
Field_type WITH "C",;
Field_len WITH 10,;
Field_dec WITH 0
APPEND BLANK
REPLACE Field_name WITH "Time",;
Field_type WITH "C",;
Field_len WITH 8,;
Field_dec WITH 0
****** Создаем базу данных **********************
CREATE Dost_mod FROM Struc
CLOSE ALL
ERASE Struc.dbf
But I would like to write programs more compactly and visually and to use possibility of creation of databases at a task of their structures in the form of two-dimensional massifs.

Code: Select all
DbCreate( cFileName, aStructure, "DBFNTX" )
first:
DbCreate( (cFileName), aStructure, "DBFNTX" )
second:
permissions ??

Hi,
Sure the file doesn't exist by a previous test? Always check before dbcreate.

The created file before creation isn't present in the folder. But by experience I know that if it and is - that is recreated. And what permissions? Strange that other databases are quietly created by that program which I gave as an example, and this concrete base - No. I tried to change names of fields, to do them without gaps before quotes and so forth, it turns out nothing. And the old way with this base too doesn't work.
I thank.

hi
i make a copy of your source to my programm with "copy and paste"
the fieldtype of "type_model" and "Int_krit" was after paste "?" not "C" !!!!
please overwrite this two characters with "C" an test again
by me- the function create the DBF correct
