Custom MessageBoxes?

[jweinraub]

Hi,

Before my software gets installed, I like a messagebox to be displayed, with a warning. I want the end user to select a checkmark that says [ ] Yes, I agree to the terms.

The [ ok ] button should not be enabled until the yes is checked. Other wise the user chooses cancel to quit.

How can this be accomplished? EULA field is not appropriate here, I think. Because it is not a licence, its a warning.

Though if EULA has to be used, I want it so that the entire message is scrolled to the bottom before yes/no is enabled.

The message box text is not that long, however, i just need the enduser to read and accept this message. a warning box in the oninit field would be where I want this to occur.

Thanks so much!

Custom Messageboxes:

But I don't think you can (temporarily) disable a button.

I think you better go with a license page.
To force scroll down:

Tip: Forcing License scrolldown is both utterly useless and extremely bad practice. Forcing a scrolldown will NOT force anyone to actually read it. You'll probably only end up annoying your users.

If you want people to read your license, it's a much much better idea to make the license EXTREMELY short. Say, ten lines tops.

i'm not aware of another messagebox plugin but the one mentioned. you might have to use nsDialogs instead. i'm not sure if you can use a different UI for nsDialogs pages, that way you could use something of the size of a messagebox.

i really hope that nsDialogs will one day allow the customization of all parts of a standard nsis installer: including messageboxes, components and instfiles page.

i agree with your opinion about license scrolldown, but don't forget there are legal reasons for the length of some licenses

Okay, I agree with your scrolling thing. I hate it too.

Our licence is very long due to the legal departments requirements. In fact we have two EULAs for hardware and software needs.

I thought a third EULA would be out of the question.

This is a warning message, more a legal disclaimer that pretty much doesnt hold us responsible if an enduser uses a new feature irresponsibly and it causes harm to humans and/or property kind of thing.

The department wanted a warning message that the user had to read, but the check mark he wanted that stated, "I have read the above and agree to its terms..."

Is there a way to say build this kind of dialogue in C++, compile it as a dll?

The warning note is fairly wordy (163 words total) but I am thinking of genericising it so i can pass the text as a string and have the rest of hte behaviour.

Something like this:
