如何实现，也是一道简单的题目
在project Source中判断是否存在ips.ini文件
会的人很简单！！！！
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
String sPath;
int iFileHandle;
char *p,*k,*f;
String sTemp1,sTemp2;
int iLenTemp1,iLenTemp2;
sPath = ExtractFilePath(Application->ExeName)+"ips.ini";
f = "\r\n";
try
{
Application->Initialize();
if (!FileExists(sPath))
{
我的问题是：如果sPath不存在，则打开fmSysSet
设置完毕后程序继续执行！如何实现？？？？？？？？？？？？
iFileHandle=FileCreate(sPath);
sTemp1 = "[IPS]";
sTemp2 = "Num=";
iLenTemp1 = sTemp1.Length();
iLenTemp2 = sTemp2.Length();
p =sTemp1.c_str();
k =sTemp2.c_str();
FileSeek(iFileHandle,0,2);
FileWrite(iFileHandle,p,iLenTemp1);
FileWrite(iFileHandle,f,2);
FileWrite(iFileHandle,k,iLenTemp2);
FileWrite(iFileHandle,f,2);
FileClose(iFileHandle);
在此处如何加入代码！
}
Application->CreateForm(__classid(TChatForm), &ChatForm);
Application->CreateForm(__classid(TfmSysSet), &fmSysSet);
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
return 0;
}

try
{
Application->Initialize();
if (!FileExists(sPath))
{
fmSysSet=new TfmSysSet(Application);
fmSysSet->Show();
fmSysSet->Update();
iFileHandle=FileCreate(sPath);
...
}
...
delete fmSysSet;

先在Project->Option里把fmSysSet设为动态生成
然后
#include"" //加上fmSysSet的头文件
WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
String sPath;
int iFileHandle;
char *p,*k,*f;
String sTemp1,sTemp2;
int iLenTemp1,iLenTemp2;
sPath = ExtractFilePath(Application->ExeName)+"ips.ini";
f = "\r\n";
try
{
Application->Initialize();
if (!FileExists(sPath))
{
TfmSysSet *fmSysSet=new TfmSysSet();
fmSysSet->ShowModal();
fmSysSet->Update();
delete fmSysSet;
iFileHandle=FileCreate(sPath);
sTemp1 = "[IPS]";
sTemp2 = "Num=";
iLenTemp1 = sTemp1.Length();
iLenTemp2 = sTemp2.Length();
p =sTemp1.c_str();
k =sTemp2.c_str();
FileSeek(iFileHandle,0,2);
FileWrite(iFileHandle,p,iLenTemp1);
FileWrite(iFileHandle,f,2);
FileWrite(iFileHandle,k,iLenTemp2);
FileWrite(iFileHandle,f,2);
FileClose(iFileHandle);
在此处如何加入代码！
}
Application->CreateForm(__classid(TChatForm), &ChatForm);
}
catch (Exception &exception)
{
Application->ShowException(&exception);
}
return 0;
}
