Summary 0004560: JclAppInst - incorrect CMD strings
Description Hi!

Today I've downloaded the latest revision of JclAppInst.pas 2523 since the one included in official JCL 3110 caused serious exceptions.
JclAppInst.pas 2523 seems to work fine except parsing command line params.
Command line parameters are incorrectly received.
There are probably some string encoding problems. The strings are incomplete and sometimes contain strange chcracters.
In my application I always pass input file paths as a command line parameters so the issue is in this case really serious and that's why I decided to report it here.

Hi jfudickar and thanks for your response.
Here is my sample uploaded.

How to use:
- Run JvAppInstances_CMD.exe (and do not close this instance).
- Open CMD and navigate to JvAppInstances_CMD directory.
- Run another instance of the executable via CMD with one long parameter, i.e.:
JvAppInstances_CMD.exe "This is my cmd parameter as a sample for this jcl control"

Fixed in JCL SVN.

The WM_COPYDATA parameter cbData was used as "Length" for strings. But Windows doesn't know that we transfer UTF16 strings and only allocates "cbData" Bytes. This caused a truncation of the strings.
