Q. Copy-Paste is possible from GEdit - GEdit, and GEdit to Textbox of any other application. But Copy-Paste is not possible from any of windows textboxes to GEdit control?
Ans.:
Every
clipboard has its own formats which allows to copy valves only of its
format.GEdit clipboard format is ISCII 8.so any other clipboard which support
this format will allow to copy the content.
Q. GEdit allows pasting text even if the control is Read-Only?
Ans.: This problem is rectified with the GIST SDK version 2.7 and above
Q. All the data is entered using GIST card in DBase-III+ under DOS. Now we want to switch over to windows and database will be in Access. The dbf files have been converted to Access tables but the scripts are not readable. We have GIST SDK and also Leap Office software for Windows environment?
Ans.: Gist CARD database format is PC-ISCII. Please convert PCISCII format to ISCII format. The API is provided with GIST SDK in the form of PcIscii2Iscii
Syntax
int
Pciscii2Iscii(unsigned char *Pciscii, unsigned char
*Iscii)
Description
This will convert a PC-ISCII string to
ISCII.
Q. GIST SDK evaluation copy when downloaded from the WEB site does not work properly?
Ans.: Please click here to get the updated and latest copy.
Q. I am Using GIST SDK / ISM Office for displaying Indian languages data in XML. The database is in Access. The front end used is VB. The data is stored as ISCII. While displaying in IE 5.5, the data in Indian languages are displayed as junk, whereas English data is displayed properly. What could be the problem?
Ans.: This occurs because when the data is displayed on the WEB a font tag needs to be attached with the data if the data is already converted to ISFOC format. If not then first the data is to be converted from ISCII to ISFOC and then displayed on the WEB using the Indian Language Font Tag (whichever font format it was converted to).
Q. Does
GIST SDK supports ASP / Dynamic pages?
Ans.: No. GIST SDK is not a web
tool. You have to use iPlugin for Web applications.
Q. Is it possible to use the fonts available with GIST SDK
on MS-Word?
Ans.: No. It is not possible to use
the fonts available with GIST SDK with MS-Word.
Q. Does SDK Support Oracle?
Ans.: GIST SDK is a front end utility tool and its working is possible on all the front ends which supports active X controls. So be it ORACLE, SQL or for the matter DB2 which are databases GIST SDK has no role to play. Only in case of Oracle you need to check out whether it saves data in 8 bit format (by default it saves as a 7 bit data).
Q. How to use GISTSDK with D2K?
Ans.:
1. Create a form and data
block in forms 5.0 and above.
2. On it draw an ActiveX Control
3.
Insert a Gedit object by right clicking on this control. Also set the OLE-CLASS
to that of Gedit
4. Use the OLE importer under the program menu to insert
the Gedit along with required method Pakages and or event Packages (selecting
all is recommended).
5. Create another data block manually and drag-drop
the control on it. (lets call it 'EDITBLOCK')
6. For this block
set
Single Record to 'Yes'
Database Datablock to 'No'
Maximum Records
fetched to '1'
7. Write the properties you want the control to have in
the 'WHEN-NEW-FORM-INSTANCE' trigger
use the functions available in program
units to do
so.
eg:
GISTOCX_DGEdit.ScriptName(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),'Devanagari')
;
GISTOCX_DGEdit.FontType(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),0)
;
where
0 is Bilingual
1 is
Monolingual
GISTOCX_DGEdit.FontName(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),'DVB-TTSurekh')
;
GISTOCX_DGEdit.KeyboardType(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),0)
;
where
0 is INSCRIPT
1 is Phonetic
2 is typewriter
8. to
reflect the changes in the control use 'WHEN-NEW-RECORD-INSTANCE'
trigger to
assign the value to gedit's text
property.
eg:
GISTOCX_DGEdit.Text(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),:SDKTRIAL.NAME)
;
OR
IF :SDKTRIAL.NAME IS NULL THEN
GISTOCX_DGEdit.Text(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),0)
;
ELSE
GISTOCX_DGEdit.Text(GET_INTERFACE_POINTER('EDITBLOCK.GEDIT'),:SDKTRIAL.NAME
) ;
END IF;
(as NULLs may give OLE errors)
9.use the
'ON-DISPATCH' trigger of the control to transfer data to back to the text-item
for example.
eg:
:SDKTRIAL.NAME:=
GISTOCX_DGEdit.Text(GET_INTERFACE_POINTER('GEDIT')) ;
(you can type in
the keydown\keyup\keypress event)
10. set the visible property of this
related item to 'No' so that end user does not see this item having ISCII
chars.
note : in the above examples
a) the data block which is
connected to database is called SDKTRIAL (it is also the name of the table).
Here's how to create the table:(Oracle Syntax)
create table sdktrial (roll
integer, name varchar(35));
insert into sdktrial values (14,
'amit');
commit;
b) the data block with ActiveX control in it is called
'EDITBLOCK'.
c) 'Name' is the name of the text item which is to store iscii
data
Q. Is there any sample applications on
for D2K?
Ans.: Please Click this link for the sample application SAMPLES (Download Winzip for extracting the files). Once Done please go through the read me file.
Q. How to generate a report in D2K when the data is stored in ISCII format?
Ans.:
This is
report which calls ismapi32.dll on client side thru reports. It uses
oracle foreign function interface package. This package is also available in
forms. Sample file (RDF file) is available here
.
