Process::MainWindowTitle Property
Gets the caption of the main window of the process.
Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| InvalidOperationException | The MainWindowTitle property is not defined because the process has exited. |
| NotSupportedException | You are trying to access the MainWindowTitle property for a process that is running on a remote computer. This property is available only for processes that are running on the local computer. |
| PlatformNotSupportedException | The platform is Windows 98 or Windows Millennium Edition (Windows Me); set ProcessStartInfo::UseShellExecute to false to access this property on Windows 98 and Windows Me. |
A process has a main window associated with it only if the process has a graphical interface. If the associated process does not have a main window (so that MainWindowHandle is zero), MainWindowTitle is an empty string (""). If you have just started a process and want to use its main window title, consider using the WaitForInputIdle method to allow the process to finish starting, ensuring that the main window handle has been created. Otherwise, the system throws an exception.
This property is not available on this platform if you started the process with ProcessStartInfo::UseShellExecute set to true.
The following example starts an instance of Notepad and retrieves the caption of the main window of the process.
#using <System.dll> using namespace System; using namespace System::Diagnostics; int main() { try { // Create an instance of process component. Process^ myProcess = gcnew Process; // Create an instance of 'myProcessStartInfo'. ProcessStartInfo^ myProcessStartInfo = gcnew ProcessStartInfo; myProcessStartInfo->FileName = "notepad"; myProcess->StartInfo = myProcessStartInfo; // Start process. myProcess->Start(); // Allow the process to finish starting. myProcess->WaitForInputIdle(); Console::Write( "Main window Title : {0}", myProcess->MainWindowTitle ); myProcess->CloseMainWindow(); myProcess->Close(); } catch ( Exception^ e ) { Console::Write( " Message : {0}", e->Message ); } }
