I'm trying to write a C++ .NET program that will move an image very quickly across the screen. Maybe all the way across in one second. What would be the easiest way to do this? All the timer functions perform incorrectly at intervals small enough to do what I want, so i'm looking for a different solution. Will GDI+ do it, or do I have to move to DirectX? I'm looking for something simple, hopefully, but that wont be excessively choppy... only moving at about 2-3 pixels at a time hopefully, so the interval would have to be around 4-5 milliseconds. Again, timer functions dont work correctly at intervals this small.......... thanks for the help!

Firstly I'd suggest bypassing the whole problem by using an .AVI animation and the Animation common control. If that doesn't work for you, I'd suggest looking into the multimedia timers[^].

Hi,

I am new to VC++, i am trying a win32 application in which i need to know the position on the screen where the user is typing. I need to know the X and Y screen co-ordinates, where the characters being typed shows up.

We can know the key pressed with the help of Windows hooks, but don't know how we get the position where it shows up.

Can we know the keyboard cursor blinking position on the screen?

Please help me on this.

Thanks in Advance.

Hi,

Thank you for your help. I tried with the below sample code
to understand "getCaretPos", but i am always getting the output
always as " 0 0 "

POINT *ptemp = new POINT;
while(1)
{
if(!GetCaretPos(ptemp))
printf("ERRORRRRRRRRRR \r\n");
printf("%d %d", ptemp->x, ptemp->y);
Sleep(500);
}

Am i missing anything?
please help.

Thank you

Icons

I had this working perfectly before, but now it's all screwed up, even after doing a clean-build.

I have 2 icons in my resources

<br />
#define IDI_ICON1                       301<br />
#define IDI_ICON2                       302

The first problem is I want the main icon for the exe to be ICON1, at the moment it's ICON2 and refuses to change. The taskbar icon is ICON1, no problems there. The title bar is the default WIN32 icon. I use the following code to change this but still my icon is not being displayed.

dw = GetClassLong(hDlg,GCL_HICONSM);
HANDLE icon = LoadImage(hInstance,MAKEINTRESOURCE(IDI_ICON1),IMAGE_ICON,16,16,LR_DEFAULTSIZE);
dw = SetClassLong(hDlg,GCL_HICONSM,(LONG) icon);
dw = GetClassLong(hDlg,GCL_HICONSM);
dw = GetLastError();

According to the code, the icon was set, but it refuses to display.

Send WM_SETICON to the window to change its icon.

assuming you have an MFC app, look at overriding the CDocument::CanCloseFrame() method

Your second link recommends "So, you need to learn something about Windows operating sytem architecture. This means, at the very least, you need to read Inside Windows whatever-is-the-most-recent-version."

Actually the book's title was changed to Windows Internals, Fourth Edition[^] for the most recent edition. I'd like all my drivers to be written by people who have read and understood this book.

Actually I think it's quite useful for those of us who have never ventured into kernel mode.

You can use these API's:
FindFirstFile()
FindNextFile()

Somethings seem HARD to do, until we know how to do them.
