Declare an .ico file

[eoredson]

Using this code produces an error when icon file does not exist.

Code: (Select All)

' set title icon
If _FileExists("sic64.ico") Then
  $ExeIcon:'sic64.ico'
  _Icon
End If
_Title "SICK64"

what am i doing wrong?

Erik.

I tried this code:

Code: (Select All)

$If _FILEEXISTS("SIC64.ICO") Then
      Print "exists."
$End If

[bplus]

If .ICO file is in same folder as bas source and you Run with Output Exe to Source Folder AND you are not finding the .ICO file then try ".\MyName.ICO" instead of "MyName.ICO".

If .ICO file is in same folder as bas source and you Run with Output Exe to Source Folder AND you are not finding the .ICO file then try ".\MyName.ICO" instead of "MyName.ICO".

I am not trying to find the existing icon. I am wondering about the ide error when icon file does not exist.

The metacommands are typically pre-compiler directives that are evaluated as a first pass over the source code.  Similar to $Include, the IDE validates the $ExeIcon metacommand interactively to ensure a valid file is specified.

I think if you want to conditionally set the icon after checking for its existence you would want to use the _ICON method instead.

And if it does not exist?

I managed to use _icon using the following code but I had to use Paint to convent the .ico to a .bmp file:

Code: (Select All)

' set title icon
i& = _LoadImage("SIC64.BMP", 32)
If i& < -1 Then
  _Icon i&
  _FreeImage i&
End If

Hi eoredson
sorry but I cannot find your 

Icon files are not supported with _LOADIMAGE and an error will occur.

at that linked page that you have posted. 


Yes there is no .ICO in the list of files that _LOADIMAGE can load,
however I find very good the section of the wiki about icon at this link Icon and Cursor
and at wikipedia page ICO file format.
In the same wiki there are the sections:
Create icon bitmaps
Create icons from bitmaps
Save Icon 32


about your specific question
"if does the file .ICO not exist?"

I remember that professional developing tools use to warning the user about a missed resource need for create the executable file...
pasting this code in QB64pe Ide I got this error because there is no such file in the path of QB64.exe where is the temp file of current code of ide.




and so it seems doing QB64pe...
so I miss the meaning of your message.
Please can say me it in other words?
