Need larger window

[Magnum]

I have a very old program that has a fixed size window.

Because of declining vision, I need a larger window.

It doesn't use CreateWindow, what would it use instead ?

Thanks.

[dedndave]

there are a few CreateDialog functions
possibly the dialog is in resource - try res hacker

[Magnum]

I found this.

extrn CreateDialogIndirectParamA:dword ; Create   a modeless dialog box from
         ; a dialog box template   in memory

This is kind of silly,...but, you can invoke GetDesktopWindow. Then, with that handle you can obtain the Device Context: GetDC.
Then,...and this is the fun part,...you can display some data using a huge font.
Here is a link to MSDN GDI Functions: Windows GDI. Microsoft tells you that these functions are obsolete and, not to use them in new programs,...but, they work great,...and, are especially annoying if your legacy app was written in MFC.

[Magnum]

I don't call your posts silly. 

Is this the right thing that needs some larger sizes and if so which one do I need to change.

MAGNUM,
I didn't mean that your question was silly,...I mean't that my suggestion was silly (because. normally you wouldn't want to overwrite the display on the Desktop).
It will, however, work. And, it will work with any available window.
Probably the best solution would be to invoke: CreateWindowEx, and then display data in a HUGE font. This can then be destroyed immediately

[Magnum]

I don't have the source, so that's why I am looking to change some instructions in the .exe to have it display a larger window.

The program displays a set of 10 timers that I use a lot for brewing tea, conspiracy theories, etc.  :t

The window is 286 pixels wide but I can't find that to make it larger.

I read up DIALOGEX and WM_INITDIALOG and how they use CreateWindowEx.

Andy

[sinsi]

Doesn't Windows have a zoom/magnifier tool?

[Magnum]

It does but it's a little cumbersome.

I found another timer that's larger.

[TWell]

If you mean to modify old exe, just use ResourceHacker or another dialog editor to change dialog font size bigger.
With poide.exe it's possible too.

[Magnum]

I need the window larger, not a larger font.

Andy

Unless making the font larger would make the window larger.

[japheth]

Unless making the font larger would make the window larger.

It will. However, there's no guarantee that you can change the font size in the dialog template - the font parameters are an optional part of the dialog resource ( DS_SETFONT flag must be set ).

[xandaz]

  Maybe if you were to step into a CreateWindowEx call, you'd realise there's a more manual way of doing it. Just a thought of course. I never did it.

[Magnum]

I found the CreateWindowEx call using IDA but I can't find out how to get to it using Ollydbg.

If I can get to it, it should be simple to give it larger width and height values.

Andy

[Magnum]

I found this, but no where can I find where any of the parameters are passed.
