关于c++bulider的串口问题，请高手指点一下!!

[josereyes]

我的程序如下：
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
if(MSComm1->PortOpen==true)
{
Button1->Enabled=false;
Button2->Enabled=true;
Button3->Enabled=true;
Button4->Enabled=true;
Shape1->Brush->Color=clGreen;
}
else
{
Button2->Enabled=true;
Button2->Enabled=false;
Button3->Enabled=false;
Button4->Enabled=false;
Shape1->Brush->Color=clRed;
}
void __fastcall TForm1::Button1Click(TObject *Sender)
{
if(MSComm1->PortOpen!=true)
{
MSComm1->CommPort=StrToInt(ComboBox1->Text);
MSComm1->Settings=
ComboBox2->Text+","+
ComboBox3->Text+","+
ComboBox4->Text+","+
ComboBox5->Text;
MSComm1->InputMode=0;
MSComm1->PortOpen=true;
Button1->Enabled=false;
Button2->Enabled=true;
Button3->Enabled=true;
Button4->Enabled=true;
Shape1->Brush->Color=clGreen;
}
在调试中却出现以下错误：Project new002x.exe raised exception on class EConvertEorror with message ''com1' is not a valid integer value'.Process stopped.Use Step orRun to continue.
请问应如何解决？？
