Delphi external control problem, the master into 150

By defining the public variable pub id, which page to switch to will assign a different value to it, and the rest of the work will work according to the value of this variable, which is simple, reliable and practical.

Isn't it okay to loop the subhandle, so why bother?

h:=getwindow(h,gw_child);

h:=getwindow(h,gw_hwndnext);

onchange event: The page is switched and the page is set off.

onchanging: Triggered when the page is switched, the allowchange parameter can specify whether to allow the switch.

The current time is recorded in the onexit event of the tabsheet.

The event record time should be hidden from the page, which is more reliable.

2.Turn on the other party's host camera, one is the same as multiple, it's very simple, but the transmission speed and effect need to be studied. Regarding turning on the camera that the other party has occupied, this issue has not been studied.

I have been engaged in remote control for a long time. It's been a long time since I've done it. I hope the master downstairs will help answer!

alert("Please enter your description of the resource, thanks! ");

return false;

else if(<2 |>20)

if(isdigit(name)){

This is a long time to say, leave QQ to say it slowly.

There are some Trojan programs for reference, but mainly in C languages, and Delphi is not common.

Seeing you ask like this, it's obvious that you can do it once.

Then it's okay to do it five times with a loop.

Able to run normally under Windows 7. After installation, run as an administrator. If that doesn't work, manually add delphi$$ to rename and then run.

It's the bin under the folder and the following is changed.,Mine is ok You try.。

If you use a data module, you must use it before connecting to the database. statement.

Your tablelists are defined in **??

When was it created?

To make your program friendly and robust, you need structured exception handling.

Change the calcscore function to read as follows:

function s1, s2: string): real;

vari,j: extended;

begintryi := strtofloat(s1);

except

on econverterror do

beginshowmessage(s1+'Not a legitimate decimal place! ');

i:= ;end;

end;tryj := strtofloat(s2);

except

on econverterror do

beginshowmessage(s2+'Not a legitimate decimal place! ');

j:= ;end;

end;result:=i*;

end;A similar situation is strtoint (str[15]) and so on.

Of course, you can also check in the onexit event of edtscore1, and you don't need to handle the exception.

It's too long... Lazy looking.

But this error must have something to do with the number you entered.

Combobox selection is equivalent to pressing the button of another form?

form1 use form2 (use the control in form2) and write the following **procedure : tobject) in the onchage of combobox);

end;end;

end;end.

form2 writes procedure : tobject in the onclick event);

end;procedure : tobject);

beginmessagebox(0,'Press 2 too! ~','Tips',mb_ok);

end;end.
