把计算机名转换为大写或小写字符

现用WordFunc.nsh头文件可以实现，于是记一下方便大家。
;从注册表中读取当前计算机名
ReadRegStr $R1 HKLM "SYSTEMCurrentControlSetControlComputerNameComputerName" "ComputerName"
MessageBox MB_OK "计算机名$R1"
;把字符串转换为大写，如果转换为小写则把+改为-即可，还可以设置某些字符不转换哦
${StrFilter} "$R1" "+" "" "" $R2
MessageBox MB_OK "转换后的计算机名$R2"
;把计算机名全部改为大写
WriteRegStr   HKLM "SYSTEMCurrentControlSetControlComputerNameComputerName" "ComputerName" "$R2"
WriteRegStr   HKLM "SYSTEMCurrentControlSetControlComputerNameActiveComputerName" "ComputerName" "$R2"
WriteRegStr   HKLM "SYSTEMCurrentControlSetservicesTcpipParameters" "NV Hostname" "$R2"
WriteRegStr   HKLM "SYSTEMCurrentControlSetservicesTcpipParameters" "Hostname" "$R2"
WriteRegStr   HKLM "SYSTEMControlSet001ControlComputerNameComputerName" "ComputerName" "$R2"
WriteRegStr   HKLM "SYSTEMControlSet001ControlComputerNameActiveComputerName" "ComputerName" "$R2"
WriteRegStr   HKLM "SYSTEMControlSet001servicesTcpipParameters" "NV Hostname" "$R2"

WriteRegStr   HKCU "SoftwareMicrosoftWindows MediaWMSDKGeneral" "ComputerName" "$R2"
