Create a font using a type converter.

[NAlvar]

Hello,

I', attempting to convert a string description into a font and I'm successful except for updating the style.
I'm using a type converter, here is the code:

Dim tobj As Type = obj.GetType

Dim pi As PropertyInfo = tobj.GetProperty("Font")

Dim propvalue as string = "Tahoma;10"

Dim valueobject As Object = TypeDescriptor.GetConverter(pi.PropertyType).ConvertFromString(propvalue)

With this propvalue, it works. The valueobject created is a font. But I can't define the style of the font, because if I assign the propvalue as follows:

Dim propvalue as string = "Tahoma;10;Bold"

an exception is throwed:

Run-time exception thrown : System.ArgumentException - Failed to parse Text("Tahoma;10;Bold") expected text in the format "name, size[units[, style]]".

Does anyone know what text should be into propvalue?

Thanks in advance.

NAlvar,
as the error message indicates, you are missing the units (pixels, points, inches, ...).

Valid values for Units: Px, Pt, Pc, In, Mm, Cm, %

This easier code works for me:

        Dim obj As Font = New Font("Tahoma", 10)
        Dim propvalue As String = "Tahoma,12Pt,Bold"
        Dim valueobject As Font = System.ComponentModel.TypeDescriptor.GetConverter(obj).ConvertFromString(propvalue)

Hope it helps

Dear DeepButi,

thanks for your advise, but it doesn't work to me.

After executing your example code, the font defined into the valueobject is the default font :

?valueobject.ToString
"[Font: Name=Microsoft Sans Serif, Size=8, Units=3, GdiCharSet=1, GdiVerticalFont=False]"

Have you got more ideas?

Tot i aixÃ*, grÃ*cies per l'ajuda.

NAlvar,
oopppsss

Dim propvalue As String = "Tahoma,12Pt"

works ... and I assumed "...,bold" would also, but it doesn't.

Unable to find the correct names for styles. Will check it.

PS. De res home, per això estem

NAlvar,

    Dim propvalue As String = "Tahoma,12Pt,style=bold"
    Dim valueobject As Font = System.ComponentModel.TypeDescriptor.GetConverter(Font).ConvertFromString(propvalue)

(easier: obj is not needed)

Hope it helps
