 Posted: Mon Dec 19, 2005 5:45 am Post subject: help! Saving and reloading control variables |
 |
|
I save my GUI's controls for the user to an ini file upon exit, and reselect them on load. I find that sometimes, when I reload the program (I think exiting works ok) some controls are not preselected and the ini file does not reflect what should have saved the last exit.
My first question is... is there a better way to save and load controls?
Second.. why is it missing save's occasionally? do I need more delays?
Third.. I think it may have something to do with when the program is reloaded. An example is onexit, it still saves controls, and if the controls aren't loaded (say you pause before the UI is even built) then it will write blank entries.
Thanks for any help... |

I use ini files to store the settings in a GUI. It always worked for me and I have complex GUIs, so it must have to do with your code. Please post a small part that demos your problem. Delays are normally not necessary.

Apparently this has been happening more often then I thought, especially in check boxes.. it also happens on normal exits, not just reloads. So I bet this is an error on my part.
I use ini files also. In the main ini file is a section called Saved.
After the GUI's controls have been created, it calls LoadSaved, which is something like:
| Code: |
LoadSaved:
IniRead, History, file.ini, Saved, History
IniRead, Option1, file.ini, Saved, Option1
IniRead, Option2, file.ini, Saved, Option2
IniRead, Option3, file.ini, Saved, Option3
IniRead, Option4, file.ini, Saved, Option4
IniRead, Option5, file.ini, Saved, Option5
IniRead, Option6, file.ini, Saved, Option6
IniRead, Option7, file.ini, Saved, Option7
IniRead, Option8, file.ini, Saved, Option8
IniRead, Option9, file.ini, Saved, Option9
IniRead, FastLoad, file.ini, Saved, FastLoad
GuiControl, Choose, History, |%History%
GuiControl, Choose, Option1, |%Option1%
GuiControl, Choose, Option2, |%Option2%
GuiControl, Choose, Option3, |%Option3%
GuiControl, Choose, Option4, |%Option4%
GuiControl, Choose, Option5, |%Option5%
GuiControl, Choose, Option6, |%Option6%
GuiControl, Choose, Option7, |%Option7%
GuiControl, Choose, Option8, |%Option8%
GuiControl, Choose, Option9, |%Option9%
GuiControl, , FastLoad, %FastLoad%
Return
|
OnExit, GuiClose, etc, goes like this:
| Code: |
Save:
Gui, Submit, NoHide
IniWrite, %History%, file.ini, Saved, History
IniWrite, %Option1%, file.ini, Saved, Option1
IniWrite, %Option2%, file.ini, Saved, Option2
IniWrite, %Option3%, file.ini, Saved, Option3
IniWrite, %Option4%, file.ini, Saved, Option4
IniWrite, %Option5%, file.ini, Saved, Option5
IniWrite, %Option6%, file.ini, Saved, Option6
IniWrite, %Option7%, file.ini, Saved, Option7
IniWrite, %Option8%, file.ini, Saved, Option8
IniWrite, %Option9%, file.ini, Saved, Option9
IniWrite, %FastLoad%, file.ini, Saved, FastLoad
ExitApp

Try to call this label before you create the GUI. That way you can specify checked/unchecked values in the control's option at run time. Example: | Code: | IniRead, CheckedValue, settings.ini, GuiPreferences, ExampleCheckbox, 0
Gui, Add, Checkbox, Checked%CheckedValue%, Control |

Great, I put that in, and I can see how it might improve the GUI.
I'm not sure how I could use this method to preselect a DDL.. maybe some help there?
It also still doesn't suggest as to why the save procedure is failing. It's as if it thinks there is nothing in the controls and thus, saves nothing.  I can tell its doing this because when a control doesn't reload like it shold, it shows in the ini file that there is nothing there.. and the only time it writes to the file is when it quits. |

There are numerous reasons for why it didn't work before. Without inspecting all of the code, I can't really pinpoint the problem. I doubt that a bug in AutoHotkey was causing the situation, most likely a typo somwhere in your script or an invalid command?  |

I think it would be helpful also if we could see how you are adding these controls in the GUI. Anyway, here is something similar to what I use for working with an ini file
| Code: |
guiTitle := "Save Config"
Gui,Add,Edit,voption1 w150,% ReadINI("option1","1")
Gui,Add,Edit,voption2 w150,% ReadINI("option2","2")
Gui,Add,Edit,voption3 w150,% ReadINI("option3","3")
Gui,Add,Edit,voption4 w150,% ReadINI("option4","4")
Gui,Add,button,,Save Config
Gui,Add,button,,Read Config
Gui,Show,,%guiTitle%
return
buttonSaveConfig:
Gui,+disabled
saveConfig(guiTitle)
gui,-disabled
return
buttonReadConfig:
Gui,+disabled
readConfig(guiTitle)
gui,-disabled
return
;this one loops through the controls in the window,
;looking for edit controls
SaveConfig(window)
{
Global cx_defaultWebsite
HWND := WinExist(window)
WinGet,ControlList,ControlList,ahk_id %HWND%
Loop,Parse,controlList,`n
{
If inStr(a_LoopField,"Edit")
{
ControlGetText,char,%a_loopField%,ahk_id %HWND%
StringReplace,val,a_loopField,edit
saveINI(GetVarName(val),char)
}
}
}
;;use this one to load changed configurations
ReadConfig(window)
{
Global cx_defaultWebsite
HWND := WinExist(window)
WinGet,ControlList,ControlList,ahk_id %HWND%
Loop,Parse,controlList,`n
{
If inStr(a_LoopField,"Edit")
{
StringReplace,val,a_loopField,edit
GuiControl,,% getVarName(val),% ReadINI(GetVarName(val),"")
}
}
}
getVarName(val)
{
If val = 1
rtn := "option1"
Else if val = 2
rtn := "option2"
Else if val = 3
rtn := "option3"
Else if val = 4
rtn := "option4"
return rtn
}
saveINI(key,val)
{
configFile := slash(a_scriptdir) "file.ini"
SplitPath,a_scriptname,,,,OutNameNoExt
IniWrite,%val%,%configFile%,%OutNameNoExt%,%key%
}
ReadINI(key,defaultVal = 0)
{
configFile := slash(a_scriptdir) "file.ini"
SplitPath,a_scriptname,,,,OutNameNoExt
IniRead,val,%configFile%,%OutNameNoExt%,%key%
IF (Val = "Error")
val := defaultVal
Else if inStr(val,"`n")
StringReplace,val,val,`n,`r`n
return %val%
}
slash(dir)
{
StringRight, slash,dir, 1
IfNotInString, slash, \
dir = %dir%\
Return %dir%

There is also a distinction between Choose and ChooseString. Are you saving the position of the DDL, or the Contents of it? |

Titan: I realized that might be a possible way, but that creates a new entry for the DDL, duplicating what already exists.. that's why I used GuiControl, Choose instead. I could use this method but.. this particular part of the code (loading) doesn't seem to be the culprit.
ranomore: Thanks for your code, although its a bit over my head, I'm going to take a look at it and hopefully be able to take some advantage of it.
The controls are added in no particular manner:
Gui, Add, DropDownList, vOption1 gSubmit w200, |First Option: %option1%|Second Option: %option2%|etc|etc|
And wow, I just realized I've been using Choose this entire time. In the docs, I noticed that if Choose isn't an integer, it will use ChooseString anyways though. I did some testing and it SEEMS like maybe this was the problem. Not sure how but.. this could have been it. I'll have to test it more. |

If you always want to save the position of the selected drop down item (instead of the text), you need to use the AltSubmit (http://www.autohotkey.com/docs/commands/GuiControls.htm) Property:
Gui, Add, DropDownList, vOption1 AltSubmit gSubmit w200, |First Option: %option1%|Second Option: %option2%|etc|etc| |
