Why does my program not work?
It works perfectly when you input the ASCII key 5 but if you input anything else like real words it doesn't seem to operate at all and i can't seem to get the HEX to ascii to work either.
Please explain i am so upset with this program

Instead of using a quote to fill with code, use the code tool.

So you want us to go through several hundred lines of code, with nothing more to go on than "it's broke"? How about a little more information, such as the error you're getting when you try to run it. If it is simply hanging up, you can put the following at the top of the screen to help you figure out where it is failing:

Opt("TrayIconDebug", 1)

MikahS,

Please stop suggesting people use the [ code ] tags - BB codes are not necessarily honoured by the new editor.  It is now recommended to use the editor "code" button.

​The problem arises when the **ASCII to Hex*** and the ****INPUT your text**** functions are inserted. If you are to run the program without these (in the code below) and encrypt 5552 the encryption and the decryption process function correctly  hence i think the problem is in the two functions before.

@Melba23,

I am having an off day, as I remember Jon saying essentially that.

My apologies.

​I think i have used the code tag correctly, can you please help me?

Yes, you have done it correctly.

What functions in your script is the **ASCII to Hex*** function and the ****INPUT your text**** function?

So you want us to go through several hundred lines of code, with nothing more to go on than "it's broke"? How about a little more information, such as the error you're getting when you try to run it. If it is simply hanging up, you can put the following at the top of the screen to help you figure out where it is failing:

Opt("TrayIconDebug", 1)

 

​The problem arises when the programs are put together

The input to text part takes the input from the user to store it in a variable. 

***ASCII to Hex*** takes the input and turns it into Hexadecimals so that the encryption can be processed. .

MikahS,

Please stop suggesting people use the [ code ] tags - BB codes are not necessarily honoured by the new editor.  It is now recommended to use the editor "code" button.

​if you guys are still interested in helping me, i have found the exact problem with my program. Their wasn't any problem with the ASII to Hex conversion or the input part of the problem. The problem is when you introduce the space button into the program, as said before if you input "5552" the program works perfect but if you input "55 52" the program doesn't seem to encrypt correctly. It for some reason can't seem to detect the space between the numbers

Why aren't you using the Crypt.au3 encryption functions to encrypt whatever it is you're encrypting? At least you'll know that they've been tested and work and are at least as secure as they can be, rather than trying to invent your own encryption functionality and having the encryption broken in 10 seconds.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

​i thought i was using the crypt.au3 function? I believe it is stated on line 3. 
And i am doing this for personal pleasure, i won't be sending my card details using this encryption technique.

​You have it included in your script, but no where in your script are you actually using any of its functions. BTW, you have a $keyvalue variable in your TextInput function that isn't used anywhere else in your script. I don't know what that value is supposed to be used for, but you're not using it anywhere.

​I have figured out the problem. When the input from the user is converted into hexadecimals it goes something like this "32 32 02 05 54" the AES program doesn't recognise the space between each digit and hence cannot function properly. I need a program that deletes this space so it becomes "3232020554". That way it will be able to read the input data. It's kind of bad, can you guide me how to do this please?

​Why are you converting the text into a hexadecimal number anyways? Just take your text , feed it to one of the encryption functions in Crypt.au3 and be done. BTW, if you want to strip whitespace from a string you might want to look in the help file and look at the string functions listed in it.

      Hello Everyone! 
      I'm attempting to create a checklist app that performs other functions. For performance, I would like to check the box, then have the button to the right enabled. After that button is pressed, the second checkbox is enabled, and ready to be checked, allowing the second button to be pressed. After the second button is pressed, the completion/exit button is enabled/shown. I have my code that currently creates the GUI, creates the checkbox, but when you check it it enables the button and the next checkbox. Can't seem to figure out a Case for GUISetOnEvent. Any assistance would be appreciated!
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <StaticConstants.au3> #include <EditConstants.au3> #include <MsgBoxConstants.au3> ; Below is the GUI interface _DeploymentProcess() Func _DeploymentProcess() $aStep1 = GUICreate("Deployment Process", 475, 345, 500, 175) $CBcStep1 = GUICtrlCreateCheckbox("1. Step 01.", 15, 25, 300, 25) $BTNS1 = GUICtrlCreateButton("Email 01", 365, 25, 90, 20) $CBcStep2 = GUICtrlCreateCheckbox("2.

      Hi everyone,

      Is there a way to determine whether the script that is running, is already running, without using;
       
      If WinExists ?

      Or is there a way to use "If WinExists" to determine the script itself?

      The reason I am asking this is because if I want someone to run the .Exe I have and they rename it to whatever they want, how could I then determine in the script to check if there's already an .Exe open, or the script itself is already open?

      Should I use Class, or how do I achieve this?

      Thanks in advance.

      Id like to build a little helpertool for my boss in office but i dont know how to sart it.
      thats no complicated task. im working for an insurancecenter and have to search the customers in different orders and different tags.
      due to my boss is old and not really commen with pc he saves the customers without system.
      eg, customer andreas statham got an insurenca for his car then i got to search for
      andreas statham car, andreas car statham, car andreas statham, statham andreas car, statham car andreas, car statham andreass etc to find all the files from this customer in the harddrive.
      some customers also are fmiliarnamed in one file like andreas statam and monika rog are married an both got a carinsurance then i got to earch for
      andreas statham monika rog car, andreas statham monika car rog,.... this can take real long to find the right customer if i do it from hand.
      how can i realise this someone in here got an excamlple script or has any sugestion?

      Ok so im using this program. clarify for school. I would like to have a program that takes every word i type in microsoft word and searches on it in claryfi. is this possible. I would like to have the program not stopping me from typing more after that word. Like when i type a word it auto search it on clarify without making me stop typing and if i want to change i can do that and if im fine that word i can just keep typing and it will search after the next word.

      Is this possible to make program works like in diagram? There is so much encryption methods and UDFs are they give security? If the $Address will be crypted with some encryption algorithm could be possible to get the value of $Address in easy way? Of course We know its easy too look into autoit code and get value of variable and so We dont want to anyone see $Address value - there are functions Could func1.au3, func2.au3.. be for example func1.php or other type of file? As we know .php files are unnable to see. For example func1 would be read by FileRead() and then Execute() Is this generally possible to do?
      Will it give secure?
      What do you think about? Maybe there is something wrong in this concept or missed.
