Hi Folks
I would be grateful if you woulg give me your thoughts on the following problem.

Using the below code

var MyDLL = LoadDLL( SYSTEM_PUBLICATION_DIR + "TestCallDLL.dll" );
if (MyDLL)
{
varPickedColour = MyDLL.CallFn("ShowColourPicker", true, "slong", "hwnd", 0, "slong", varPickedColour );
if (varPickedColour != -1)
{
PolygonClockFace.SetFillColour( varPickedColour );
}
}

varClockColour=varPickedColour;

I then write to disk file to varClockColour

When reloading pub I read from disk file to varClockColour

then

PolygonClockFace.SetFillColour(varClockColour);
Does not work

Checked the varClockColour variable and the number is fine.

Also if I make varClockColour =255
then
PolygonClockFace.SetFillColour(varClockColour);
This works fine?

Why does the write/read to/from file not work.
Cheers
Paul

Hi Paul,

I think you might be muddling something up. There is no read / write to a file in this script. The DLL loads the Colour Picker window and then passed the colour selected to the variable with is used to set the polygon.

This bit does work!

It might be daft, but I have to ask, you have put the DLL in the publication folder?

Regards,

Mack

Sorry Mack,
Yes the colour changes fine and I used actions for the read/write to disk file.

Check out attached. Once colour is picked it should load on pub startup.

Hi Paul,

Posting executables generally won't help and most people would be skeptical of running foreign programs. Also, writing files to the root drive is not good practice - better of using the publication directory or the user's documents or temp.

As for the problem, try replacing the corresponding line with this:

Hi Mack
Sorry for the indiscretions, rushed it abit.
New line works perfectly, would never have got that in a milion years.
Cheers and thanks
Paul

Not a problem.

The reasoning is that the text file reads in a string and the parameter required is a number.
