// using Mid
CString str = _T("abcde");
CString s = str.Mid(2, 3);

// using Right
s = str.Right(3);

you certainly not searched the web that much...

MSDN give you this : CString::Mid()[^]

CString s1 = "abcde";
CString s2 = s1.Mid(2, 3);

You get your answer with CString::Mid but maybe its helpful for you

<br />
extract right part from String<br />
	CString str_T("abcdef");<br />
	CString s;<br />
	s=str.Right(3);//def<br />

<br />
extract left part from String<br />
	CString str_T("abcdef");<br />
	CString s;<br />
	s=str.Left(3);//abc<br />

<br />
And CString::Mid extract middle part from string

Your question is a bit too confusing to understand. What does "dial the numbers from command lines" mean? What exactly are you trying to do?

still moving the mouse

Hi there, I'm in need of help to move the mouse to any position on my program's window. I got help, and was told to use the SetCursorPos() function. This moves the mouse to a point on the screen and not on my window. How can I get my window's top and left position so that I can use

SetCursorPos(window.left + x, window.top + y) //x and y are the position on
//my program's window

?

Are there better ways of doing this?

thanx...

KOM UIT DAAAAA!!!

first take ur window's cordinate using the GetWindowRect function.then move the cursor to that position.

CRect WindowRect;
GetWindowRect( WindowRect );
SetCursorPos(WindowRect.left + x, WindowRect .top + y)

You may use GetWindowRect(...) to Get the window co-ordinates
Also ClipCursor(...) to confine the cursor to a rectangular area on the screen

You want to use the function GetWindowRect to get the window coordinates. From that you can then call
SetCursorPos and apply the correct offsets.

x_coord+=x_offset;
y_coord+=y_offset;

Search for GetWindowRect on google and it should take you to the msdn page for that function.

You don't write the pointer to a file. You write the data which the pointer points to.

char* string = ...;
FILE* pStream = fopen("file", "w");
fwrite(string, 1, strlen(string), pStream);

File System Methods

Hi,

I'm trying to write a program that can copy a file URI into any window by drag and drop.

The problem lies in C++, so far i've found only two methods:
GetLogicalDrives and GetLogicalDriveString.

In .NET there is this eqivalent:

Environment.GetLogicalDrives and
DriveInfo.GetDirectories.

Im wondering if there is any eqivalent in Visual C++

Thanks

Tom

David Crow20-Sep-06 4:03

What does a URI have to do with GetLogicalDrives() or GetLogicalDriveString()? How does drag/drop relate to all of this? Please explain what it is that you are after.

Ok, My app is supposed to display a tree view of the file system, you can then select the file you want. Then you drag a cross hair like in Spy++, to the window and it will copy the absolute path of the file to the location you dragged the crosshair to.

I know that can be done without an app been written, but in some windows that don't support drag/drop operations, eg. Lan Connections Screen in Internet Options.

Dragging the cross hair over the selected area will retreive the handle of the control and send a WM_PASTE message to that control and paste the file path into the selected window.

Smile | :)

As soon as you start dragging from your tree control, are you sending a TVN_BEGINDRAG notification message?
