Re: c# program to move a window on desktop from a side to another when it looses focus ayandelhi27-Jul-10 17:58 ayandelhi 27-Jul-10 17:58  i want to make a program which can replace the desktop window manager in window... i want my program to handle all the open windows like the way i want it to... is it possible... a window opens it comes to center. when it looses focus of when i'm done with it it goes to either side of screen.. Dwm does it in a different way, it minimizes the windows to taskbar until again activated..and it restores the window in the last opened place...

All-in-all it's not worth the trouble.

If you want a smooth version of this, you'd have to rewrite part of the Win32 API. There is no namespace or class in the .NET Framework that can do this for you. The only way you can do it is if you used a couple of the Win32 API functions, constantly polling for the foreground window and moving it when it appears. This will introduce a flicker as you have to wait for the window to show up in one spot then move it, painting the window twice in two different spots. There is no way to avoid this.

C# program to block user input(both mouse and keyboard) until a specific keyword(password) is entered ayandelhi27-Jul-10 8:37 ayandelhi 27-Jul-10 8:37  HI!! i was thinking abt such a program which can block the inputs from keyboard n mouse until i enter the password... is such a program possible or m just thinking haywire... plz guide me... and one more thing can i control the flow of data from a USB Drive. I mean no data should move automatically (viruses) from USB to PC and vice-versa. if user initiates a copy/move operation, the data can move... Can i???

Re: C# program to block user input(both mouse and keyboard) until a specific keyword(password) is entered ayandelhi27-Jul-10 18:05 ayandelhi 27-Jul-10 18:05  that is wat i was thinking.. but what if the application in pace of blocking the input simply does nothing on the inputs until a specific combination like ctrl+p is pressed to enter password... but the mouse still remains inactive.. no other key should be able to work.. like alt+tab which is used to change minimized windows should not be able to work... win button should be deactivated... and many more like it... so tell me... and the USB stuff... i want to to monitor the data which moves without user involvement... viruses just copy them self from usb to pc and fro.. this is very annoying...

I think it's called the Windows logon screen.

Re: C# program to block user input(both mouse and keyboard) until a specific keyword(password) is entered aj.esler28-Jul-10 1:28 aj.esler 28-Jul-10 1:28  Should be pretty easy with some sort of low level hook that blocks input. If the password is x chars long, just keep the last x chars in memory but block them from going any further. If the last x chars match the password, allow any subsequent mouse or keyboard input to go through. This[^] article should provide a good starting point. The faq also explains how to block keyboard input. How come I get a rounded number when I multiply doubles?? [modified] roman_s27-Jul-10 5:52 roman_s 27-Jul-10 5:52  How come I get a rounded number when I multiply and assign value to a double?? dbRecipeTotal = (RI.Quantity / dbRecipeTotalQuantity) * (InvItem.Price / 100); double dbRecipeTotal = 0.0; RI.Quantity is = 28.88887 dbRecipeTotalQuantity is = 28.88887 InvItem.Price is = 2425 I get dbRecipeTotal = 24.0 in quickview it should be 24.25 Any help is appreaciated modified on Wednesday, July 28, 2010 9:44 AM Re: How come I get a rounded number when I multiply doubles?? harold aptroot27-Jul-10 6:03 harold aptroot 27-Jul-10 6:03  Is InvItem.Price an integer? If so, divide it by 100.0 instead of 100 edit: or you could multiply dbRecipeTotalQuantity with 100 before dividing RI.Quantity by it, that might be a bit quicker - is that important here? Re: How come I get a rounded number when I multiply doubles?? Luc Pattyn27-Jul-10 6:06 Luc Pattyn 27-Jul-10 6:06  Your subject line claims you're multiplying doubles, I guess you are not. Assuming InvItem.Price is an integer, InvItem.Price / 100 is too. if you hadn't used parentheses around it, the result would have been correct. The better approach however is to use either floating-point or decimal for all quantities that aren't integer by their very nature, here Price.

Re: How come I get a rounded number when I multiply doubles?? T M Gray27-Jul-10 9:01 T M Gray 27-Jul-10 9:01  Whenever you do math between two number types you should expect your answer will be in precision of the lowest precision operand. You should either declare the 100 as a constant of the appropriate type or use Numeric type suffixes[^]. Re: How come I get a rounded number when I multiply doubles?? William Winner27-Jul-10 9:24 William Winner 27-Jul-10 9:24  Try making 100 100.0 instead. It's taking price and dividing by an integer which forces the result of the operation to an integer. Telling it that 100 isn't an integer by adding the decimal point should give you the right answer. Re: How come I get a rounded number when I multiply doubles?? T M Gray27-Jul-10 10:12 T M Gray 27-Jul-10 10:12  Just adding a .0 isn't good practice. Do you know for sure what type it becomes by adding a .0? It could be a decimal, or a float, or a double. Even if you know what type the compiler chooses by default, will other people who have to read or update your code? See my previous post in the thread for how to make sure the number you are dealing with is cast as exactly the type you need.
