Overview
The ConsoleGetHandle function retrieves the handle associated with a specific console window.
Syntax/Parameters
Syntax
handle = ConsoleGetHandle ( [int id] );
Parameters
id
An optional int specifying a console ID from 0 to 7. If omitted, the default console window ID of 0 is returned.
Return Value
Returns a handle value or NULL_HANDLE on error. Use the GetLastError function to retrieve a formatted error code.
Remarks
The handle value returned is a window handle when operating as a Windows application or a pseudo handle for the command line console window. The pseudo handle is not the handle to the actual shell that executed the script but rather an internal semaphore for standard input and output.
Example
In the following example, the console handle is retrieved to use the AddMessage function to write to the console.
string list[];
int ix;
handle hCon;
AddMessage("This is the default log");
ConsoleOpen();
hCon = ConsoleGetHandle();
AddMessage(hCon, "File dump to console:");
list = EnumerateFiles(GetScriptFolder() + "*.*");
while (list[ix] != "") {
AddMessage(hCon, " %2d : %s", ix, list[ix]);
ix++;
}
AddMessage("This is the END of the default log");
In this example, the ConsoleOpen function is inert when running as a console application; however, it is needed when running in the IDE since, unlike the ConsolePrint function, the AddMessage function will not automatically open a console in the IDE. As a console application, the messages (file list) are dumped to the console and then the default log. Under the IDE, the default log appears in the Information View and a console window will contain the files.
