CarlTBarnes / RemoveFileWithAPI.clw
Last active May 17, 2022
REMOVE() in RTL has bugs and is very slow using ShFileOperation(). My replacement uses API DeleteFile() and sets Clarion ErrorCode() so can replace REMOVE().
View RemoveFileWithAPI.clw
!There are a few Remove() things here, what you want is FileApiRemove FUNCTION(STRING Fn2Delete),LONG,PROC
!In C8 Clarion REMOVE() was enhanced a second parameter with flags to allow wildcards, recursion, etc
!It was changed from calling API DeleteFile() to use the much more complicated ShFileOperation()
!This makes it much slower and more bug prone
!My replacement FileApiRemove() uses API DeleteFile() then sets the Claion Error so it can replace
!an existing REMOVE() in Clarion code. If you are using Remove(FILE) you'll need REMOVE(Name(File))
!or you can create a FileApi2Remove(FILE FileRef) that calls FileApiRemove(FileRef{PROP:Name}) or NAME()
!I named it "FileApiRemove(" so if you are searching "REMOVE(" you'll file it, versus RemoveUsingAPI() would not.

Report Manual Paging Class and Template
View ReportManualPaging.clw
!This CLASS was written to **replace page checking code** in reports that was in many places
!For most all people the **replace** comment will NOT apply.
!This is not an easy an easy thing to do. I cannot explain it all here.
! Steps to Implement ManRpt Class
!1. Add the Extension Template ReportLineHeightMaxSet Template so all lines have
! a. Sets all DETAIL PROP:MaxHeight=Height so line Height is exactly correct
! b. For all DETAILs defines LnHt_Label LONG variable and sets = DETAIL PROP:Height for use with Height calcs
CarlTBarnes / Option2DropList.clw
Last active Apr 30, 2021
Replace OPTION with LIST,DROP - find all OPTION controls on a Window and generate a LIST,DROP() with FROM('Text#Value') as the RADIO('Text'),Value('valuie') plus PROMPT
View Option2DropList.clw
! Version 2 - DROP and No DROP in one procedure. FORMAT() and ~Header option
! Generate LIST,DROP,FROM() reading OPTION and RADIOs -- or LIST without DROP
! Option + Radio's take mnore space that a LIST,DROP,FROM('radio|radio|radio')
! The Option can be easier for the User and more obvious of all the choices without dropping
! Some times you don't have the space, or too many Options can be visual clutter
Option2DropList PROCEDURE() !Add this to your program and a button on the Window to call it,
MODULE('RTL') !Global MAP Requires this

Menu Open Message WM_INITMENU to modify menus before opening
View MenuOpenMessage.clw
!Often right when Menus are being opened you want to change the Menus
!based on the other variables and things.
!Simple example of SubClass Window to get a WM_INITMENU Message before Menus display
!This adds Time to an Item text to show it changing at time it opens
!It also adds Time when closed, you get a Message when window close also WM_EXITMENULOOP

Backup Clarion Project BAT files
View Bak_and_Zip_Sample1.bat
@REM This will backup the File Extensions listed below for ROBOCOPY to a subfolder
@REM then zip using PowerShell to a file named: ProjName_Date_Time.ZIP
@REM I place this BAT file in the Project folder named: _Bak_and_Zip_ProjBane.bat
@REM This backs up to a sub folder named _Bak_ under the project, some times I place this folder elsewhere
@REM This saves the CLW that allows for doing a code compare
@REM -----------------------------------------------------------------
@echo off
for /f %%I in ('wmic os get localdatetime ^|find "20"') do set dt=%%I
REM dt format is now YYYYMMDDhhmmss...

ChooseColor API function instead of Clarion ColorDialog()
View ChooseColorAPI.clw
!Clarion's ColorDialog() does not have the deatures of the API ChooseColor like saving the 16 custom colors
!A few changes to Larry's code by Carl:
! Set cc.rgbResult = W{PROP:Color} before call. Should CC_RGBINIT be conditional?
! Check for ChooseColor returning True with IF ccBool THEN .
! Comment UnlockThread.
! Prototype a (LONG cc) so no need for type at Map level. Add DLL(1)
