Thanks so much Guffa
But how to allocate the size of memory on the heap and return the address of memory cell(memalloc(size)) and return memory block (memfree(addr))?
I'm not good at these stuff
Pls help me to solve out.
Thanks
eric

As I said, the .NET heap doesn't work that way. There are no methods to allocate memory on the heap.
You can create an object that contains the amount of data you need, but you can't safely access it using pointers without using the fixed keywork to pin the object in memory.
Freeing objects in the heap is handled by the garbage collector. When you don't have any references to the object any more, it's up for garbage collection, and will eventually be collected.

AllocHGlobal allocates unmanaged memory, not memory from the heap as the OP requested.
But then again, not all posters know what they are asking for...

b { font-weight: normal; }

Nitpicking, but the OP did not mention anywhere that he wanted memory from the managed heap

its me again.
im still trying to send two commands to command prompt from c#. no luck yet.
the first command needs to change the current directory path to: c:\Program files\progressive projects\progress\reporttemplates
the second command needs to run a batch file inside this directory called fop.bat
my most recent attempt is....
string command=@"\\fop.bat -xml " + "\\ClientReportCard.xml " + "-xsl " + "\\" + Convert.ToString(TempName) + ".xsl " + "-pdf " + Convert.ToString(Salon.Library.GlobalVariables.Reports_Path) + "\\ClientRecordCard.pdf";
ProcessStartInfo startInfo = new ProcessStartInfo("cmd.exe");
// /c switch sends a command
startInfo.Arguments = "/C " + @"cd" + Convert.ToString(TempPath);
// redirect messages to this program
startInfo.RedirectStandardError = true;
startInfo.RedirectStandardOutput = true;
//don't execute using shellexecute API
startInfo.UseShellExecute = false;
//Don't open command prompt window
startInfo.CreateNoWindow = false;
System.Diagnostics.Process p = System.Diagnostics.Process.Start(startInfo);
startInfo.Arguments = "/C " + command;
startInfo.RedirectStandardError = true;
startInfo.RedirectStandardOutput = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = false;
System.Diagnostics.Process pp = System.Diagnostics.Process.Start(startInfo);
string output = p.StandardOutput.ReadToEnd();
string error = p.StandardError.ReadToEnd();
string output2 = pp.StandardOutput.ReadToEnd();
string error2 = pp.StandardError.ReadToEnd();
p.WaitForExit();
if (output.Length != 0)
shellControl1.WriteText(output);
else if (error.Length != 0)
shellControl1.WriteText(error);
BUT with this it executes the one command and forgets the directory path and then executes the second command. In this way it can't find the batch file. please help. iv been stugling with this on for days now.

O ja,
Do any of you know how to execute a batch file directly from that file path.
I type (in command prompt)
c:\program files\progressive projects\progress\reporttemplates\fop.bat
I get an error saying:
'c:\program' is not recognized as an internal or external command, operable program or batch file.
if i can find a way to run that command with one shot i'll be fine
Please help.

Put it in double quotes. To see how, simply drag the bat file from Windows Explorer into a command prompt.

Thank you thank you thank you.
I can't believe i've been strugling with this one for little less than a week.
THANK YOU.......

hi
I want to be able to do the following:
Type mytype = MethodInfoArray[i].GetParameters()[0].GetType();<br />
mytype[] p = new mytype[5];
Is that possible?
cheers
|

You are looking for Array.CreateInstance[^]. You can use it like
Type mytype = MethodInfoArray[i].GetParameters()[0].GetType();
Array a = Array.CreateInstance(myType, 5);

Thank you ... that worked great ... but I should hae explained
The bacis problem I have is this:
Type requiredtype = getType();<br />
Object[] datafrominputs = getData();<br />
MethodInfoArray.Invoke(new Object(),new Object[]{datafrominputs});
Basically the method will take a single array as its parameter, but I need to be able to convert may Object array to the right type. What should I do?
cheers

Yeah I have but I get:
InvalidCastException: "Object must implement IConvertable"
I was trying to convert from an Object[] to an int[].
cheers

Did you call Convert.ChangeType on the array itself or did you loop through the array and call it for each element in the array? I think the first approach won't work.

y that's an idea... when looping through I would have to store the array in type determined at runtime (using the array class, I think). How could I then pass that as a parameter?
thanks for all the help

Try this piece of code
static Array ConvertArray(object[] arr, Type type)
{
Array a = Array.CreateInstance(type, arr.Length);
for (int i = 0; i<arr.Length; ++i)
{
a.SetValue(Convert.ChangeType(arr[i], type), i);
}
return a;
}
