在VS2003里开发PPC2002程序:如何在在程序中打开另外一个已存在的应用程序!

pc模式下可以用shell ，或者进程操作。。。但是ppc开发模块下。。这几个东西好像都不行。

调用shell api 可以正常编译。但是在机子上就是不行。。打开来就是错误。说找不到。shell的动态链接库。。。
倒。。哪里去找这个动态链接库。

不是这个意思。。。我是想调用一个外部程序。。

nSize = fileName.Length * 2 + 2;
pFile = localAlloc(MemoryAllocFlags.LPtr, nSize);
Marshal.Copy(Encoding.Unicode.GetBytes(fileName), 0, pFile, nSize - 2);

nSize = parameters.Length * 2 + 2;
pParams = localAlloc(MemoryAllocFlags.LPtr, nSize);
Marshal.Copy(Encoding.Unicode.GetBytes(parameters), 0, pParams, nSize - 2);

see.lpFile = pFile;
see.lpParameters = pParams;

ShellExecuteEx(see);

LocalFree(pFile);
LocalFree(pParams);
//return see.hProcess;
}

public static void Start(string fileName)
{
Start(fileName, "");
