Masked edit field question

I'm creating a custom dialog with a masked edit field. I'm not sure what to use in the mask.
Right now it is <#####-#####-#####-#####-#####>
this work but only lets me enter numbers. What should I use for Alphanumeric in the mask?

That mask will still let me enter in %^&* and charators like that. Is there a way to mask out those? I just want letters and numbers.

You are correct, this format allows all characters. So you just want a limited set [0-9][A-Z][a-z], correct?

Unfortunately I have not found a way to implement a mask that does this. I just have to check the results and report back to the user that they entered an illegal character.

I went back to the instructions for the Masked Edit control on MSDN and I am a bit confused by the instructions.

Look at this quote:
The alternate digit, %, and alternate alphanumeric characters, ^, ?, and ` fields allow custom actions to differentiate between fields in a way that can be controlled by the mask, for example, ^ can be used for fields that should be uppercase.


Our use of the carrot symbol, ^, does not force upper case characters, so perhaps my understanding of the rules is incorrect.

Hopefully Robert or Michael can chime in on this.

I am wondering if the following would work <@^#^@^# ... >

There was another post a while ago concerning this that I found:

Unfortunately it came to the same conclusion is that the masked edit control does not provide the level of filter needed to limit this to strict alphanumeric characters [0-9][a-zA-Z]. Too bad they did not support regular expressions for a filter that would be the best type of implementation.

I normally write installs in installscript and can do most anything there but my company wants me to look at converting to MSI installs.
I know in installscript and can make the fields do what I want them to do.

Well, with IS2009 and windows installer 4.5 support of the embedded UI you could use an InstallScript UI if that is acceptable to the company.

Where can I get info on the embedded UI stuff?
I have been closed into installscript for so long I feel like I'm new to installs when I start working with MSI and windows installer.

For a start, please see "Using the InstallScript Engine as an External vs. Embedded UI Handler for InstallScript MSI Installations" in the InstallShield 2009 help.
