Find position for a new box

[Magnum]

I am going to add a 3rd box and would like to know if there is some tool or program that can tell me what position my cursor would be at.

Similar to what mspaint has.

It takes to long monkeying around with the values for horizontal position of window,etc.  :t
   

[dedndave]

not sure what you mean by a "new box", Andy

GetCursorPos ?

[Magnum]

One of these. It will prompt for a string to be entered.

Roll your own, it's easy, even with Masm32 only...

include \masm32\MasmBasic\MasmBasic.inc        ; download
  Init
  push eax        ; create a 2-DWORD slot on stack
  push eax
  stack equ dword ptr [esp]
  .Repeat
        mov ecx, MouseY        ; could be GetCursorPos
        mov eax, MouseX
        .if eax!=stack || ecx!=stack[4]
                mov stack, eax
                mov stack[4], ecx
                deb 4, "MouseX", eax
                deb 4, "MouseY", ecx
        .endif
  .Until MouseK==2
  pop eax
  pop eax
  print "bye"
  invoke Sleep, 1000
  Exit
end start

you can use EQUates to set the width of the buttons
and measure the dialog client width with GetClientRect
subtract the 3 buttons and divide by 4 - use that for the spacing
that way, whatever you make the dialog, they will be evenly spaced

Does this "monkeying around" have to do with specifying coordinates and sizes in a dialog template that will result in some desired control placement and size in pixels?

[Magnum]

I have two buttons now and want to add a third.

I was going to use screen co-ordinates that I thought would be good for placing the 3rd box.

Probably next to the other two.

Andy

For later...

I know how to change the size of the window that the button are in, but I would like the window to center itself on the screen if that is possible.

[MichaelW]

You didn't answer my question. In a dialog template positions and sizes are specified in dialog template units, see Dialog Box Measurements. If you prefer to work directly in pixel units, a straightforward method is to use an application window instead of a dialog, and create the parent window and the controls with CreateWindowEx.

[dedndave]

to get the screen size

Code Select Expand

    INVOKE  GetSystemMetrics,SM_CXSCREEN
    INVOKE  GetSystemMetrics,SM_CYSCREEN

let's say your window sizes are EQUates...

Code Select Expand

MAIN_WIDTH  EQU 400
MAIN_HEIGHT EQU 300

and your window position values are global variables

Code Select Expand

dwPosX dd ?
dwPosY dd ?

Code Select Expand

    INVOKE  GetSystemMetrics,SM_CXSCREEN
    sub     eax,MAIN_WIDTH
    sar     eax,1
    mov     dwPosX,eax
    INVOKE  GetSystemMetrics,SM_CYSCREEN
    sub     eax,MAIN_HEIGHT
    sar     eax,1
    mov     dwPosY,eax

now, when you create the window, you want X, Y, W, H...

Code Select Expand

dwPosX,dwPosY,MAIN_WIDTH,MAIN_HEIGHT
that will center the window on the screen

I didn't understand what you were asking for.

My code uses MessageBox to prompt for the file name.

I will read up on Dialog Boxes.

what you want is GetOpenFileName

Hutch has a macro called OpenFileDlg that will make it easy for you
it is documented in masm32\help\hlhelp.chm

that macro calls the masm32.lib function OpenFileDialog if you don't like macros

[Magnum]

Already using it.

I just realized that I don't need any user input at all.

My code opens a file, search for a string and replaces it.

But I still want to finish this project that will need user input.
