Compact framework 1.1
Hi, I'm trying to spin off a new process by doing something like this:
ProcessStartInfo s =
new ProcessStartInfo(ExeName);s.Arguements = CmdLine;
Process.Start(s);
I have included the proper using directives that msdn said, and the types are fine in a windows enviroment, but when I use it on Compact Framework 1.1 it isn't recognized, is there something similar I can use to create a new thread, I cannot update this device to CF 2.0

This works for me in 1.1:
Process proc = new Process();
proc.StartInfo = new ProcessStartInfo(myExe, exeArgs);
proc.Start();
but what you have looks like it should work also. what do you mean by 'isn't recognized'.
'Error 1 The type or namespace name 'Process' could not be found (are you missing a using directive or an assembly reference?) '
Which using directive did you use for that code? That is the same error I got with the code I posted earlier only the typename was different

Thats actually the first thing I tried:
I first created a structure:
public class ProcessInfo{
public IntPtr hProcess;public IntPtr hThread;public Int32 ProcessId;public Int32 ThreadId;}
then did the imports
[
DllImport("CoreDll.DLL", SetLastError = true)]
private extern static int CreateProcess(String imageName, String cmdLine,IntPtr lpProcessAttributes, IntPtr lpThreadAttributes,Int32 boolInheritHandles, Int32 dwCreationFlags,IntPtr lpEnvironment, IntPtr lpszCurrentDir,Byte[]bArray, ProcessInfo pi);then in the function:
ProcessInfo pi = new ProcessInfo();if (File.Exists(ExeName)){
if (CreateProcess(ExeName, CmdLine, IntPtr.Zero, IntPtr.Zero,0, 0,
IntPtr.Zero, IntPtr.Zero, new byte[128], pi) == 0){
int i = Marshal.GetLastWin32Error();EditText(
"Errror2: " + i.ToString());return 42;}
}
This gives me an error code 126, Module cannot be found
Process does not exist in .NET CF 1.0
as for the error on not finding the module, could be because the exefilename/path is incorrect.
are you able to post the code you used to PInvoke (which you have), including the method you call it giving it the arguments/parameters?

this is the PInvoke
DllImport("CoreDll.DLL", SetLastError = true)]
private extern static int CreateProcess(String imageName, String cmdLine,
IntPtr lpProcessAttributes, IntPtr lpThreadAttributes,
Int32 boolInheritHandles, Int32 dwCreationFlags,
IntPtr lpEnvironment, IntPtr lpszCurrentDir,
Byte[]bArray, ProcessInfo pi);
The Path is correct that was one of the first things I checked
Where is the code you are calling from?
int
ProcessReturn = CreateProcess("\\Bin\\ProcTest.exe" , "-f \\Result\\result.txt");That is where is it called,
And this is the complete function
public int CreateProcess(String ExeName, String CmdLine){
EditText(
"CmdLine: " + CmdLine);ProcessInfo pi = new ProcessInfo();if (File.Exists(ExeName)){
if (CreateProcess(ExeName, CmdLine, IntPtr.Zero, IntPtr.Zero,0, 0,
IntPtr.Zero, IntPtr.Zero, new byte[128], pi) == 0){
int i = Marshal.GetLastWin32Error();EditText(
"Errror2: " + i.ToString());return 42;}
}
elsereturn 42;WaitForSingleObject(pi.hProcess, 2000000);
Int32 exitCode;if (GetExitCodeProcess(pi.hProcess, out exitCode) == 0){
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
return 42;}
CloseHandle(pi.hThread); CloseHandle(pi.hProcess);
return exitCode;}
I have this code working in CF 1.0:
[DllImport("coredll.Dll")]
private static extern int CreateProcess(string strImageName, string strCmdLine, IntPtr pProcessAttributes, IntPtr pThreadAttributes, int bInheritsHandle, int dwCreationFlags, IntPtr pEnvironment, IntPtr pCurrentDir, Byte[] bArray, ProcessInfo oProc);
private void LaunchWeb(string url)
{
ProcessInfo pi = new ProcessInfo();
CreateProcess("iexplore.exe", url, IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, new Byte[128], pi);
}
public
class ProcessInfo
{
public int Process;
public int Thread;
public int ProcessID;
public int ThreadID;
}I recommend you to use OpenNET Compact Framework library - see http://www.opennetcf.org - the source code is still available free to download till the version 1.4 - link here. See OpenNETCF.Diagnostics namespace.
