Problems with Class not registered in my VB6 control replacement tool

Hello!

I am trying to write a VB6 frm / cls / ctl / vbp parser to be able to replace controls with other controls.

I have already solved a few riddles, but I am still experiencing "class not registered" errors, and I don't understand why.

I would therefore like to ask if somebody has some resources / documentation about .vbp files (do the entries have to "sorted"?) and .frm / .ctl files regarding their relations (Begin/End, BegingSomeProperty/EndSomeProperty) and the alphabetic sorting, etc.

Thank you!

Can you be more specific about the issue here and how it relates to tB?

Obviously you'd need to have the new controls installed just like you would for the VB6 IDE.

The controls are registered. I wrote this converter to update all my projects to use the vb common control replacements.
I noticed that unlike the vb6 controls, some of the replacement controls store their caption/text in the .frx files.
I noticed that I can also get away with normal strings in the .frm files if I use ansi strings, so I replaced e
g. "my caption":.frx.... with "simpletest".
it is one topic that I don't understand yet and which I planned to tackle last.

I would love to be able to understand where vb6 chokes without guessing and trying.

The form .log files are not helpful. The just state that the controls xy was not registered. But I see no difference to a sample project that was not processed by my converter. Apart from the frx strings.

I made it!! I overlooked a decimal separator in a property value.
It works now.
