First step: the Mscomm. SRG Mscomm32. Ocx, Mscomm32. Dep three files are copied to the system folder, note that the Mscomm control is authorized, so it should be use the "license" Licence registration in the registry, the next step is registration method, as to why do you do that, can look at the following web site: http://support.microsoft.com/support/kb/articles/q151/7/71.asp
Step 2: use under Windows registration tools regsvr32 registered the OCX controls, click on "start" - & gt;" Run ", then fill in in with (assuming installed in C disk operation, WIN2000) :

Step 3: manually create a primary key in the registry entry: in the first click on the "start" - & gt;" Run ", then fill in the regedit command to open the registry, find HKEY_CLASSES_ROOT \ Licenses, add a primary key

Completion of registration, choose the ole control in PB, mscomm32

Lb_temp=blob (" ~ h01-2 encodingUTF16BE!)
