[Gambas-user] Developing components
There is some library, written with C++. I want to use its power with Gambas. It's a static library. So, using the documentation for Gambas, I have made an empty component. But I don't know, what must be done after this.

Re: [Gambas-user] set of questions
Benoît Minisini replied: I think you should have been make a thread for each question, because now we are lost when reading the answers! Now I see the mistake. Sorry. I asked: I want to run my gambas2-application from USB-FLASH-DISK on the computers, that do not have gambas2 installed. -8-- Can I run my application with just some command, without copying? Benoît Minisini replied: -8-- I will tell you when I make the environmental variable change. His name will be something like GB_DIR, or GB_ROOT. It would be excellent to find the answer in documentation, when the technology will be done. I asked: 2) I have the GridView in my program, that displays 4 thousands of rows. When it updates the data (4-10 seconds), program do not reflexes. There is a string in the documentation: You should use the last method if you have thousands of rows to display.. I'm sorry, I do not understand this at all. Could anybody explain this on a simple example? I thank charlesg, Doriano Blengino and Benoît Minisini for excellent practical and theoretical answers. I asked: 3) When I hide persistent Form, how to display it again? Jussi Lahtinen replied: FromName.Show works with me..? And Benoît Minisini replied: Show() ? You want to ask me: What the problem is?. I often need to know, if SomeForm is already opened or yet not. I didn't find any property or method of the Form that told about it. The fastest way for me was to write such code in SomeForm class: --- ' Gambas class file PUBLIC VAR_FormIsShown AS Boolean PUBLIC SUB Form_Open() ... VAR_FormIsShown = TRUE END PUBLIC SUB Form_Close() ... VAR_FormIsShown = FALSE END --- In FMain I wrote: --- IF SomeForm.VAR_FormIsShown = FALSE THEN ... SomeForm.Show() ENDIF --- SomeForm had that slow GridView (from question №2). I wanted to make it open faster. In a month I suddenly found property Persistent. I already forgot about VAR_FormIsShown and switched it to true. SomeForm opened only ones. I suggested, that SomeForm.Show() wasn't antimethod for SomeForm.Hide() but only antimethod for SomeForm.Close(). When you answered to me , I saw my mistake. I added such code in SomeForm class: --- PUBLIC SUB Form_Hide() ... VAR_FormIsShown = FALSE END --- Now it works. Some persons are worrying about 'Hijacking', so I shall not ask: What is the best way to control if the Form is already opened?. I asked: 4) On my monitor with resolution 1024x768 Forms and widgets on them look great. But when I come to my friends with big wide monitors, some widgets (Buttons) became bigger while another widgets don't or not in such proportions. Why does it happen? Benoît Minisini replied: By default, form and control size is proportional to the height of the default font in pixels. If you don't want this behaviour on a form, just set the (Scaled) property to FALSE. Now it works correctly. :) There isn't (Scaled) in the list of Form's properties in documentation. And there is only STATIC PROPERTY READ gb.qt.Desktop.Scale AS Integer in the whole documentation. :( I asked: 1) May I create proprietary (not open-source) gambas2-applications and components for gambas2? and: 5) Can I easily convert my big project from the gambas2-project to the gambas3-project? 6) My project uses gb.qt3, gb.qt3.ext, gb.kde, gb.kde.html components. Can I easily switch them to gb.qt4 and other components, when my favour Linux-distr Debian will be updated? All is clear. Thanks.

[Gambas-user] set of questions
Using Gambas 2.7, Debian Lenny 32 -- Hello! Main question. I want to run my gambas2-application from USB-FLASH-DISK on the computers, that do not have gambas2 installed. There is a folder on my USB-FLASH-DISK with my application and subfolders: 1) bin, includes files gba2, gbc2, gbi2, gbx2, soft links; 2) lib, includes files *.so.0.0.0, *.component, *.gambas, soft links; 3) share, includes icons/*.png, info/* (strange files), mime/*.xml. It also includes bash-script for copying all above to system folders /usr/bin/, /usr/lib/ and /usr/share. Can I run my application with just some command, without copying? Another questions: 1) May I create proprietary (not open-scource) gambas2-applications and components for gambas2? 2) I have the GridView in my program, that displays 4 thousands of rows. When it updates the data (4-10 seconds), program do not reflexes. There is a string in the documentation: You should use the last method if you have thousands of rows to display.. I'm sorry, I do not understand this at all. Could anybody explain this on a simple example? 3) When I hide persistent Form, how to display it again? 4) On my monitore with resolution 1024x768 Forms and widgets on them look great. But when I come to my friends with big wide monitors, some widgets (Buttons) became bigger while another widgets don't or not in such proportions. Why it happens? 5) Can I easily convert my big project from the gambas2-project to the gambas3-project? 6) My project uses gb.qt3, gb.qt3.ext, gb.kde, gb.kde.html components. Can I easily switch them to gb.qt4 and other components, when my favour Linux-distr Debian will be updated? Some suggestions: 1) In gambas2-IDE I need the insert mode of type, that replaces the next character. P.S. Thanks to Benoît Minisini for help (Problem with UTF-8 in Gambas-connection to MySQL). The --default-character-set really was Latin1. Regards, -- Dima Malkov (Russia) -- Come build with us!

[Gambas-user] Problem with UTF-8 in Gambas-connection to MySQL
(I don't know English well) Use Debian 5 Lenny -32, Gambas 2.7 from repository. I develop an account program for russians users. It must work with cyrillic correct. I have made MySQL5 (default UTF8) database with direct CHARACTER SET UTF8 option, tables with direct CHARACTER SET UTF8 option. Then connected to it from gambas, output data to GridView. All string fields were not readable. I run example Database. It works correct with some french symbols, but with cyrillic not. Program Database manager do the same. I get sources of Gambas-2.8.2. Opened main.c file of MySQL driver, find function static int open_database(DB_DESC *desc, DB_DATABASE *db) . Add string fprintf(stderr, Character set GB[%s] mysql[%s]\n, GB.System.Charset(), mysql_character_set_name(conn)); before and after string set_character_set(db); . Compiled only this driver, copied it to /usr/lib/gambas2. Run my program. Result: Character set GB[UTF-8] mysql[latin1] Character set GB[UTF-8] mysql[latin1] in console. Why latin1 instead UTF-8? -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
