Newbie problem!?

[frose]

Hi,

we have successfully migrated our 16bit clipper application to xHarbour.com. This app is running in the GTWVG/HB_EXT_INKEY (New control keys that do not overlap with other codes) modus.

Now we want to add some FiveWin GUI elements, for example 'MessageBox( <hWnd>, <cText>, <cTitle>, <nStyle> )'.

So I have to include the 'FiveWin.ch' and here we go. But now something strange happens. There are some keycodes, e. g. "E" without any reaction and the MEMOEDIT doesn't work anymore (Argument error, operation '*', Trace Through: TDIALOG:NEW).

Is here anybody around who can help me:
- knows this problem or
- can direct me to a possible solution or
- have some other tips to find a solution
- can tell me some 'best practices' starting with FiveWin
before I'm lost in space

THX in advance

Try to not include Fivewin.ch.

Hello Enrico,
ok that works.
I guess because it's a Winapi function!?
But when I want to use FiveWin function, e. g. 'MsgNoYes( <cMsg>, <cTitle> ) --> lYesNo', I have to include the FiveWin.ch.

Frank,

If you just want to use some functions, then there is no need to include FiveWin.ch

FiveWin.ch implements the FiveWin commands to manage GUI objects.

Antonio,
without FiveWin.ch I got an unresolved external symbol '_HB_FUN_MSGNOYES'!

I don't see how this is possible. MsgNoYes() don't need include files at all, as far as I know.

done some tests with the sample altd.prg and xHarbourBuilder Professional September2008 on two windows machines: XP 32-bit SP3 (new installed virtual machine) and Vista 64-bit SP1. On both machines same behaviour:

- the original prg doesn't compile: unresolved external symbol '_HB_FUN_MSGINFO'
- ok, when including FiveWin.ch
- ok, replacing 'MsgInfo' with 'MessageBox' without FiveWin.ch

If you just want to use some functions, then there is no need to include FiveWin.ch

Additionally, I've tried to extract the part of the FiveWin.ch which make the prg run, but with no success. I thought one of these files: "Dialog.ch", "Font.ch", "Ini.ch", "Menu.ch", "Print.ch", "Colors.ch", "DLL.ch", "Folder.ch", "ODBC.ch", "DDE.ch", "Video.ch", "VKey.ch", "Tree.ch", "WinApi.ch" are responsible, but I've given up

An empty FiveWin.ch does the job! Very strange, must be something within the xBuilder, I think.

So problem with the FiveWin.ch is solved, but the root problem still exist!

Even with the emptied FiveWin.ch the app crashes, e. g. in the class TDialog (Argument error, operation '*', Trace Through: TDIALOG:NEW).

I think there are some incompatibilities between GTWVG and FiveWin that causes this crash?

If so, I think there is no chance to have a coexistant development environment between these two GUI's and no chance to migrate to FiveWin step by step

Rewriting the complete app is opportune!

Can anyone confirm this theory?

Frank,

FiveWin should not be used with other GUI libraries, or there could be symbols conflicts, and crashes.

Its worth to rewrite some parts of your application, using FiveWin, so you can use all the FiveWin capabilities. FiveWin is very easy to understand and soon you will be mastering it

[frose]

Antonio,

thank you very much for the positive and motivating words.

So first, I have to eliminate/replace all the GTWVG-Functionalities with the FiveWin matching parts.
