SQLite delete column in one table 31 七月, 2007

Posted by leterboy in Embedding System.

Data from http://www.sqlite.org/faq.html#q11

SQLite has limited ALTER TABLE support that you can use to add a column to the end of a table or to change the name of a table. If you what make more complex changes the structure of a table, you will have to recreate the table. You can save existing data to a temporary table, drop the old table, create the new table, then copy the data back in from the temporary table.

For example, suppose you have a table named “t1″ with columns names “a", “b", and “c" and that you want to delete column “c" from this table. The following steps illustrate how this could be done: 

BEGIN TRANSACTION;
CREATE TEMPORARY TABLE t1_backup(a,b);
INSERT INTO t1_backup SELECT a,b FROM t1;
DROP TABLE t1;
CREATE TABLE t1(a,b);
INSERT INTO t1 SELECT a,b FROM t1_backup;
DROP TABLE t1_backup;
COMMIT;

VB : data report 橫印問題… 13 七月, 2007

Posted by leterboy in Tech Learning.

當您在使用 VB6 中的 DataReport
時，有沒有遇到過一種情形：系統設定的印表機列印方向預設是直印，而您的報表卻是橫式的，但是您卻無法更改印表機的列印方向，除非您到控制台的印表機中去更改預設為橫印！

如果您不希望使用者自行去更改印表機的設定，您就必須在程式中幫他設定好，以下的模組檔案
Orient.bas 就是用來設定印表機的直印或橫印的，說明如下：


Sub ChngPrinterOrientationLandscape(ByVal frm As
Form)：設定為直印

Sub ChngPrinterOrientationPortrait(ByVal frm As Form)：設定為橫印

在程式中使用方式如下：

1、設定為直印：ChngPrinterOrientationPortrait
Me

2、設定為橫印：ChngPrinterOrientationLandscape Me

註１：此方法也可適用於 Crystal
Report。

註２：VB6 sp5 之後可直接使用 DataReport1.Orientation 來設定直橫印。

不可以指定紙張大小..我已經找遍了..

但可以用excel列印..以下是我以前所寫的.供您參考…..

Dim excelapp As Object

Dim excelwkb As Object

Dim excelsht As Object

Dim limitpp1 As Integer

   

Set excelapp = GetObject(App.Path & “\book1.xls")

Set excelsht = excelapp.Worksheets(1)

If smoke1 > 0 Then

   excelsht.Cells(3, 2) = smoke1

   excelsht.Cells(3, 3) = smoke1 * 49

   excelsht.Cells(15, 2) = smoke1

   excelsht.Cells(15, 3) = smoke1 * 49

   excelsht.Cells(46, 1) = “合計 " & smoke1 & “人"

end if

info from         http://www.jrsoftware.org/isinfo.php

Inno Setup is a free installer for Windows programs. First introduced
in 1997, Inno Setup today rivals and even surpasses many commercial installers
in feature set and stability.

Key features:

  • Support for all versions of Windows in use today: Vista, XP, 2003,
    2000, Me, 98, 95, and NT 4.0. (No service packs are required.)
  • Extensive support for installation of 64-bit applications on the 64-bit
    editions of Windows Vista, Windows XP, and Windows Server 2003. Both the x64 and
    Itanium architectures are supported. (On the Itanium architecture, Service Pack
    1 is required to install in 64-bit mode.)
  • Supports creation of a single EXE to install your program for easy
    online distribution. Disk spanning is also supported.
  • Standard Windows 2000/XP-style wizard interface.
  • Customizable setup types, e.g. Full, Minimal, Custom.
  • Complete uninstall capabilities.
  • Installation of files:
    Includes integrated support for “deflate", bzip2,
    and 7-Zip LZMA file compression. The installer has the ability to compare
    file version info, replace in-use files, use shared file counting, register
    DLL/OCX’s and type libraries, and install fonts.
  • Creation of shortcuts anywhere, including in the Start Menu and on the
    desktop.
  • Creation of registry and .INI entries.
  • Integrated Pascal scripting engine.
  • Support for multilingual installs.
  • Support for passworded and encrypted installs.
  • Silent install and uninstall.
