pascalscript

I'm wanting to do a basic string validation within an Inno Setup script to be relatively certain the string is an email address. I just want to see that there is a '@' character followed by a '.' character and that there is at least one character on either side of these. Something similar to this regular expression: [^@]+@.+\.[^\.] The lack of regular expressions and limited string functions available in object pascal are causing me grief. It would be simple enough to reverse the string, find the first '.' and '@' and then do some comparisons, but there's no Reverse(string) function available.

In my script I am checking whether a directory and two files in this directory exist. While the first returns the correct value, the second check does not. I've checked it multiple times that these files exist in the designated directory but Inno Setup will always tell me that they do not exist. This is happening on a virtual Windows Server, and can't be reproduced on my local machine. There it always returns the correct Value. UpdatePath := ExpandConstant('{app}'); if DirExists(UpdatePath) then begin ExePath := UpdatePath+'\Application.exe'; ConfigFilePath := UpdatePath+'\Application.exe

I want to create an application that will draw simple forms based on JSON data. I need to have a script to put intelligence on that. Is Pascal Script from RemObjects a solution for that? Is is compatible to generate application with the same source code for Android, iOS and Windows? EDIT: Extending to better understand the need: I have a delphi program that draws a form (pretty much like a dfm file, as a descriptor) and fill it with data from a database. However there is a need for inteligence to validate the data entered. Since the form and data and the validation rules are done by the user

In my Inno Setup installer I need to make sure a shortcut to a certain file is present in a folder. The name of the shortcut is arbitrary and not under my control. I only know which file it needs to point to. If the shortcut is missing, I need to generate the shortcut. If it is already present, it must not be created again. I guess that it is somehow possible to iterate through all shortcut files in the relevant folder and check which file they point to. In a comment to an answer to Shared Shortcuts/Icons , a IShellLink interface is mentioned, but I don’t know how to make it available in the

I have three components and if the user select any component it will do installations. Now I want to disable the Next button if the user don't select any components. I am trying if not IsComponentSelected('xxx') , but it is not working. Can anyone please help me?? Martin Prikryl There's no easy way to update the Next button state on component selection change. A way easier is to display a message when the Next button is clicked: function NextButtonClick(CurPageID: Integer): Boolean; begin Result := True; if CurPageID = wpSelectComponents then begin if WizardSelectedComponents(False) = '' then

I have managed to get a basic script working to display a wizard (using CreateInputFilePage ) for a user to identify a file location that I use to update some settings in an XML file. However, I would like to perform some basic checking of the input to the file selected rather than simply accepting whatever the user provides. For example displaying a message box if the user attempts to press **Next"* when the content is invalid. I am not entirely sure how to handle events arising from the wizard and how to apply any kind of validation rules to the data before proceeding to the next task.

I use Inno Setup to make installer for my app. When user uninstall the app I want to delete my custom folder in Program Data folder, my folder is large (about 15 GB) so I use [UninstallDelete] section to delete this folder: [UninstallDelete] Type: filesandordirs; Name: "{commonappdata}\testFolder" But when the Inno Setup gets to the [UninstallDelete] section, the progress bar is show at 20% and stop in this position for a long time, then it "jumpy" to 100%. So how to make progress bar increase steadily when uninstall the app? Thanks! I do not think it's really possible. There's no way to

I would like to be able to structure my code for my Inno Setup project but I am forced to move code around because you can't call a function unless it is defined first. Is there a way to declare a prototype at the top so that I don't get the "Unknown identifier" error and so that I can structure my code in logical blocks. In Pascal (including a Pascal Script used in Inno Setup), you can define a function prototype (aka forward declaration) using a forward keyword: procedure ProcA(ParamA: Integer); forward; procedure ProcB; begin ProcA(1); end; procedure ProcA(ParamA: Integer); begin { some

By default, when you add a TEdit to a page in Inno Setup, the height is one line. How do I increase the height of the edit? Here is the relevant part of the ISS file ContractConfigPage := CreateInputQueryPage(ServerConfigPage.ID, 'Map contract as JSON', 'Please enter the map contract to use in JSON format', ''); ContractConfigPage.Add('JSON', False); ContractConfigPage.Edits[0].Height := 100; { does not have any effect } Edit: I am now able to have a bigger edit but I can not have multiple lines ContractConfigPage := CreateInputQueryPage(ServerConfigPage.ID, 'Map contract as JSON', 'Please

I have used string in a function as follow. I'm passing a string to a particular function, if that string has single quotes inside middle it's breaking. How to include single quotes in Inno Setup Pascal scripting? TempReadValue(StrArray, 'log4j.appender.testing.File=INSERT INTO emp select Eid,'%K','%L'from DistributionTable whereEname = 'Nails:chino'', LogFileName); When passing to function its taking till %K , after that its breaking. Can anybody guide me how to read/pass entire string till Nils:chino ? Thanks for your help. Try this one: TempReadValue(StrArray, 'log4j.appender.testing.File
