Actually, replacing old VB Command buttons with the Exontrol's exButton component is just like replacing a string with another.  

You have the following options to replace the VB Command objects with the Exontrol's exButton component.

A) 

• Make the first step to add the ExButton to the VB project like any control with the project open (Ctrl+T), save and close it.

• Do the "VB.Command" search and replace in each frm file.

B)

• Open the Project1.vbp and add a reference to the exbutton.dll by adding the line ~Object={65D9132C-B295-42A0-8421-B8B1DA27C5CE}#1.0#0; ExButton.dll~ Do not include the ~ characters.

• Open the Form1.frm and add the ~Object = "{65D9132C-B295-42A0-8421-B8B1DA27C5CE}#1.0#0"; "ExButton.dll"~ reference to the form just before 'Begin VB.Form'

• Replace all ~VB.CommandButton~ with the ~EXBUTTONLibCtl.Button~ and save the form1.frm file.

Now, the idea to replace the old VB button with the new button is to use a tool that's able to find and replace strings. For instance if you have multiple vbp files adding the object reference to the files could be like follows. Look for a property in the .vbp file that could be located in all your vbp files, like VersionCompanyName ( or whatever ) and do Replace('VersionCompanyName="YourCompanyName"', 'VersionCompanyName="YourCompanyName"\r\nObject={65D9132C-B295-42A0-8421-B8B1DA27C5CE}#1.0#0; ExButton.dll'. This way you actually added the reference to the project file. The same for the file reference in the frm files where the 'Begin VB.Form' could be located.
