- Specifications for DocView Integration with external databases.
-
- (Informatik Inc. has available several utilities for special requirements,
- such as direct printing, scanning, batch conversions, etc. If you are looking
- for special functions that are not included in DocView, pleasse contact
- Informatik Inc.)
-
- The following setup is required to integrate the external database with DocView:
-
- An earlier version of DocView required a SETUP.SSU file. This file has now
- been replaced by the Docview.ini file. The setup is done via the Setup menu.
-
- Images can be viewed via the DocView program by a DOCVIEW.EXE FILENAME.XXX command
- (where FILENAME.XXX is the path name of the image file. DocView can also
- be launched from many Windows applications, such as internet browsers.
-
- The recommended interface is with DDE (Dynamic Data Interchange). If your
- database application does not support DDE, the interface can be accomplished
- with the SendKeys method. For details on the SendKeys method, please read the
- section below.
-
-
- USING THE DDE METHOD - THE RECOMMENDED METHOD
- **********************************************
-
-
- Example of a SETUP (for MSACCESS 2.0 DATABASE)
- --------------------------------------------------------
-
- Database Editing Sub-System:
-
- DDE Topic:
- MSAccess|EditForm
- DDE Item:
- TheField
- SendKeys String:
- ====leave this line blank----
-
- Database Query Sub-System:
-
- DDE Topic:
- MSAccess|QueryForm
- DDE Item:
- TheField
- SendKeys String:
- ====leave this line blank====
-
- Optional Fixed Path:
-
- D:\DOCS
-
- Image Windows Width:
-
- 60
-
- Image Windows Height:
-
- 60
-
- Image Windows State/Position:
-
- 0
-
- Items 1-3 contain information about the external database's EDITING subsystem:
- Item 1 is the DDE TOPIC (in the MS Access database system).
- Item 2 is DDE ITEM (in the MS Access database system).
- Item 3 (leave this line blank)
-
- Items 4-6 contain information about the external database's QUERY subsystem:
- Item 4 is the DDE TOPIC (in the MS Access database system).
- Item 5 is DDE ITEM (in the MS Access database system).
- Iteme 6 (leave this line blank)
-
- Item 7 (optional) specifies the fixed path name of the directory that holds
- the image files. This is required only if the image address in the
- database does not include the directory name.
-
- Item 8 (optional) specifies the path substitution. An equal number of leading
- letters of the path passed by the DDE parameter will be substituted. To
- specify the number of characters to be replaced, add the number after a
- space, for example C:\AAA 9
-
- Item 9 specifies the opening state of the parent (MDI) window:
- blank or 0 = normal, full screen size
- 1 = minimized
- 2 = maximized
- 3 = Fit-to-image, upper-left corner
- x=nnnn y=nnnn will offset the window from the left and the top
- by the nnnn values, e.g x=1440 y = 720 will place
- the window 1 inch from the left and 0.5 inches from the
- top. The window is sized to fit the image.
-
- x=right y=bottom will place the window at the absolute right and/or bottom of
- the screen.
-
- Item 10 specifies the width of the image display window. If the value is 2,
- the window opens maximized, otherwise, if the value is 100 or less,
- the entry represents a percentage of the screen width. If more than 100
- it represents the measurement in twips (1440 twips = 1 inch; 576 twips = 1 cm).
-
- Item 11 is the height of the image display window. If the value is 100 or less,
- the entry represents a percentage of the available screen height, otherwise
- it is measured in twips (1440 twips = 1 inch; 576 twips = 1 cm).
-
- item 12 represents the list of magnification ratios that you want to see in the
- Magnification menu, for example 25,50,100,150,200,300
-
-
- Item 13 represents other options:
- nosave = the Save As option in the image windows is suppressed
- printall = the default is set to print ALL pages.
-
- If you use several options, separate the options with a comma or a space.
-
- Item 14 specifies the left and top margin for the purpose of printing (inches or
- centimeters depending on the Windows setup)
-
- In the database application, you must create a script or a function for a
- DDE POKE. Use the following specifications:
-
- Application = Docview
- Topic = Linkform
- Item = Linkbox
-
- EXAMPLE OF A CODE IN THE MS ACCESS APPLICATION:
- -----------------------------------------------
- Sub TheButton_Click() 'executed when the user clicks on the TheButton.
- Dim Chan as integer
- Dim x as integer
- Dim param as string
- On error resume next
- param = [TheField]
- Chan = DDEInitiate("Docview","Linkform") ' Establish a DDE link
- if err <> 0 then ' if DocView is not yet running .....
- x = shell("C:\docview\docview.exe " & param,3) 'start up Docview. (Space after 'exe'!)
- else
- DDEPoke Chan, "Linkbox", param 'Poke the data to DocView
- DDETerminateAll 'Close the DDE link
- endif
- End Sub
-
- (Where param represents the parameter sent to DocView.)
-
- EXAMPLE OF A CODE IN AN VISUAL BASIC APPLICATION
- ------------------------------------------------
- Sub Command1_Click ()
- On Error Resume Next
- ddelink.LinkMode = 0
- ddelink.LinkTopic = "Docview|Linkform"
- ddelink.LinkItem = "Linkbox"
- ddelink.LinkMode = 2
- If Err = 282 Then
- dummy = Shell("c:\docview\install\docview.exe ddddddd", 1)
- else
- ddelink.Caption = ddddddd
- ddelink.LinkPoke
- ddelink.LinkMode = 0
- endif
- End Sub
-
- (Where ddddddd represents the parameter sent to DocView.)
-
- The database application will send (poke) the following data string to DocView:
-
- ffffffff,ttttttttt
- ffffffff,ttttttttt
- ffffffff,ttttttttt
-
- where fffffff is the file name (with path and extension), and
- ttttttt is the optional title (description) of the image.
-
- The title, if used, will be displayed in the title bar of the image.
-
- Up to 30 items can be listed.
-
- Please refer to the database application's user guide for the DDE syntax.
-
-
- Sending data from DocView to the database application
- -----------------------------------------------------
-
- When the user clicks on the Edit button (pencil) or the Query button (question
- marks) in the toolbar of DocView, DocView pokes the file name of the currently
- displayed image to the database application. The information is sent to the
- form and field specified in the setup (items 1,2 and 4,5, see above).
- In the database application, you need to write the appropriate code to handle
- the poked data.
-
- (VB Programmers please note: The 'receiving' form must have the linkmode set
- to 1 and the linktopic must agree with the topic specified in the setup.)

- Items 1-3 contain information about the external database's EDITING subsystem:
- Item 1 is the path/file name of the external database application.
- If you do not integrate, enter 'None'.
- Item 2 is the precise name of the external database application as
- shown in its title bar. If you don not integrate, enter 'None'.
- Item 3 represents the 'SendKeys' string for activating the external
- database application (more information below).
-
- Items 4-6 contain information about the external database's QUERY subsystem:
- Item 4 is the path/file name of the external database application.
- If you do not integrate, enter 'None'.
- Item 5 is the precise name of the external database application as
- shown in its title bar. If you don not integrate, enter 'None'.
- Item 6 represents the 'SendKeys' string for activating the external
- database application (more information below).
-
- Item 7 (optional) specifies the fixed path name of the directory that holds
- the image files. This is required only if the image address in the
- database does not include the directory name.
-
- Item 8 is the width of the image display window. If the value is 100 or less,
- the entry represents a percentage of the screen width, otherwise it is
- measured in twips (1440 twips = 1 inch; 576 twips = 1 cm).
- Item 9 is the height of the image display window. If the value is 100 or less,
- the entry represents a percentage of the available screen height, otherwise
- it is measured in twips (1440 twips = 1 inch; 576 twips = 1 cm).
-
- Item 10 specifies the window status:
- blank or 0 = normal
- 2 = maximized
- 1 = minimized
-
- **************************************************************************
-
- The characters are not case sensitive, except possibly item 3 and item 6.
-
- Items 1 and 2 and items 4 and 5 may (but need not necessarily) be identical.
-
-
- In the database application, you must create a 'SendKeys' script or function.
-
- If you use the 'SendKeys' link method, read and follow the instructions below:
-
- In the external database application, you must create a script/macro that copies
- the following data to the Windows clipboard, activates DocView and send
- the F12 keystroke to DocView.
-
- #F#xxxxxxxx.xxx,tttttttttt
- xxxxxxxx.xxx,tttttttttt
- xxxxxxxx.xxx,tttttttttt
-
- Where #F# is a fixed starter tag,
- xxxxxxxxxx.xxx is the file name of the image.
- The directory path must be included unless it is declared
- in the third box of the SETUP (see above).
- tttttttttt is the optional description of the file that will be used in the
- image displays title bar. If the tttttttttt is blank, the system
- uses the file name as a description. If the tttttttttt is not used,
- the comma can be omitted.
-
- Normally, you will only have one line, one file. If you specify multiple lines,
- the DocView program can display all the listed images in sequence by pressing
- a 'Next' button.
-
- As an example, a macro in Access 2.0 that sends the following keysstrokes
- (SendKeys) will activates DocView:
- ^({ESC})<{Enter}{F12}
-
-
- When the DocView user requests the external application's EDIT Form, DocView
- copies a #E#xxxxxxxx.xxx string to the Windows clipboard, starts up or activates
- the external application specified in items 1 and 2 and send the keystrokes
- specified in item 3 of the setup specification to the external edit application. The
- xxxxxxxx.xxx parameter represents the path/file name of the currently active
- image in DocView. If item 7 of the SETUP specifies a global directory path,
- the matching path is removed from the parameter. The #E# is an identifier flag.
- The SendKeys keystrokes would normally include the commands for executing a
- macro in the external database application that will pick up the image file name
- in the Windows Clipboard and process it.
-
- When the DocView user requests the external application's QUERY Form, DocView
- copies a #Q#xxxxxxxx.xxx string to the Windows clipboard, starts up or activates
- the external application specified in items 4 and 5 and send the keystrokes
- specified in item 6 of the setup specification file to the external edit application. The
- xxxxxxxx.xxx parameter represents the path/file name of the currently active
- image in DocView. If item 7 of the setup specifies a global directory path,
- the matching path is removed from the parameter. The #E# is an identifier flag.
- The SendKeys keystrokes would normally include the commands for executing a
- macro in the external database application that will pick up the image file name
- in the Windows Clipboard and process it.
-
-
- SendKeys
-
- In the example above, the %(FU)VDMACRO1{ENTER} has the following meaning:
- After opening the external application, the system sends the F and U keystrokes,
- both while pressing the Alt key (as symbolized by the percent sign). The F open
- the File menu and the U opens the Macro Request. The letters V D M A C R O 1 are
- sent followed by the Enter key. VDMACRO1 is the assumed macro name (it can of course
- be any name). For more details on the SendKeys syntax, please consult the application's
- documentation, or contact Informatik Inc.
