急!在先等,一个中断问题.

[Mr-Chen]

do
{
dwStart = GetTickCount();
SetDAV(CH,Amplitude); //发送一个电压值
DelayUS(Current_Time); //延时单位微秒级
SetDAV(CH,0); //发送一个电压值
do
{
}
while((GetTickCount()-dwStart) < 250);
}
while(B_Resert == false);
原以为只要将B_Resert置为true循环就会中断,但程序一但进入循环外界的button则均无响应,请问如何才能让该循环响应复位按钮,使其能中断循环.

bool B_Resert=false;

do
{
dwStart = GetTickCount();
SetDAV(CH,Amplitude); //发送一个电压值
DelayUS(Current_Time); //延时单位微秒级
SetDAV(CH,0); //发送一个电压值
do
{
Application->ProcessMessages();//***这一句很重要****
}
while((GetTickCount()-dwStart) < 250);
}
while(B_Resert == false);
只需采用以下方法实现就可:
__________________________________________________________________
void __fastcall TForm1::ResertClick(TObject *Sender)
{
B_Resert = true;
Application->ProcessMessages();
SetDAV(CH,0);
}
