Mark-

Thanks for the response. I tried a bunch of variations of MC_Break, setting the key, setting it off, etc.. Nothing altered what I am seeing. CTRL+ Break does not stop a sound playing with MCI_Wait or MCI_Notify, as it should. No errors are reported for any calls I am using with success or trying with no success. Well, unless I fail to open the device. I use MCI_STOP when the user selects a button and MCI_Notify is used. I do not see a command structure that uses MC_Break and actually says it will stop the sound playing. The docs do have this: "You might have to press the break key multiple times to interrupt a wait operation. " HA I just tested with MCI_Wait and CTRL+ Break, hit the key pair 30+ times, it did not stop the sound.🙂

More testing shows CTRL + Break is a toggle command and it appears after X time it resets to cleared/off. I do not see a way to query the device for its "break mode" state. CTRL + Break while another program has focus has the same result as if the program that plays the sound has focus. I have not found a way to send CTRL + Break to the system. If a method to query the state and send a CTRL + Break was possible, that would good. Might have to put a note in the user manual if the sound will not play.

Hello, Today, I discovered some code using mciSendCommand with MCI_WAIT and MCI_PLAY, I wrote when Windows 7 was the cat's meow works under W10 and I assume W11 as long as the user has not used CTRL + break on the computer. Searching the web I found a fellow reported the issue in 2016, https://answers.microsoft.com/en-us/windows/forum/all/media-control-interface-nmci-not-working-properly/4931db24-a53a-46da-94db-7423e3d5540f I verified, code works sound plays, press CTRL + break, code says it works, no errors and no sound. Restarting the computer, the code works as long as CTRL + break has not been pressed. And there seems to be another time it might be cleared but, I could not repeat that part. Rewriting the code without using MCI_WAIT is possible but, before I started, I was wondering if anyone has an idea or has found a solution? Thanks, Mark

I do not see a call to terminate the thread. Normally, for me, works like a charm. procedure TForm1.Button2Click(Sender: TObject); begin MyThread.Terminate; MyThread.WaitFor; MyThread.Free; end; //I don't do this: FreeOnTerminate := True; // Free memory when finished procedure TMyThread.Execute; begin //if an exception is thrown in the thread we need to catch it try MyExecute; except on E:exception do exceptionString:=E.Message; end; end; procedure TMyThread.MyExecute; begin while (not terminated) do begin try //some code except end; if not terminated then Sleep(sleepAmount); end; end;

Which version of Delphi are you using? 10.2, "Synchronize" is protected. I have always used Queue to access the main thread. Queue(procedure begin <some procedure>; end); But, I do not use FMX.

Thanks.

I know that works for non modal forms, never tried with modal forms. Just tried with 10.2 and OnDeactivate is not called with a modal form, unless I am doing something wrong.

I need to run the database desktop application in the tools menu of delphi 7 but these two messages come up "private directory is invalid or undefined. using temporary directory instead." and "working directory is invalid or undefined. use startup directory instead." If anyone can help me I will be grateful? So that I can continue to program my application.

Thanks. Done: https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-1709

I am using 10.2. Does the issue exist in 12.x?

Hello, I attached a very simple project that demonstrates the issue. Here, the label is 1/2 hidden by the task bar if the max width constraint is set and the form maximized. Cheers, Mark Max.zip

Hello, Delphi 10.2 If I set the form's Constraint.MaxWidth to some value, 650 for example, with the form open, normal size and maximize the form, icon, right click menu, etc., the form bottom is hidden by the taskbar. With all Constraint.MaxWidth set to 0, works as expected. No anchors, align is none. Anyone seen this? It is reproducible with all forms I tested. Web searching, no joy. Ideas? Cheers, Mark
