no accessible 'DrawText' is most specific

[DF]

DrawText is overloaded - one of which accepts a ByVal rect and the other accepts a ByRef rect. I get a "no accessible 'DrawText' is most specific" error. How can I resolve this problem by forcing VB to recognize the one I want?

Any help would be greatly appreciated.

DF,
You cannot override a method based on ByRef & ByVal, you will get a compile
error on one of the methods themselves. Primarily because VB.NET does not
have a construct to specify which one to use.

Where & How is DrawText defined that you managed to get both ByRef & ByVal
overloads?

Hope this helps
Jay

Hi Jay,

This is the code:

batchSprite.Begin(DX3D.SpriteFlags.AlphaBlend Or _

DX3D.SpriteFlags.SortTexture)

Dim rect As New System.Drawing.Rectangle(5, 5, 0, 0)

viewFont.DrawText(batchSprite, _

Convert.ToString(Val), _

rect, _

DX3D.DrawTextFormat.NoClip, _

System.Drawing.Color.Yellow)

batchSprite.End()

I'm using Visual Studio 2003. The viewFont.DrawText code above has the blue
squiggly lines underneath. When I mouseover it, I get a yellow box that
basically says "overload resolution failed. No accessible

'DrawText' is most specific." message. There are two options in the box. One
contains a ByRef rect and the other ByVal rect. Since I can't figure out how
to tell VB which one to use, I can't compile the code.

Any advice?

Thanks for you time,

DF

DF,
What type of object is viewFont (its Dim statement)?

As I stated, VB.NET does not allow you to define them, nor use them (if C#,
C++ or other language happens to define them!).

The reason VB.NET does not support them is they are not CLS compliant (as
you are finding out).

Hope this helps

Remarks

This method must be called from inside of a Device.BeginScene ...

Unless the NoClip format is used, this method clips the text so that it
does not appear outside of the specified rectangle. All formatting is
assumed to have multiple lines unless the SingleLine format is specified.

If the selected font is too large for the rectangle, this method does not
attempt to substitute a smaller font.

This method supports only fonts whose escapement and orientation are both
zero.

I'll do some checking.

Short answer, you cannot use those overloads in VB.NET.

Your choices are:
- Use C#
- Use one of the other overloads that are not overloaded on ByVal & ByRef.

DF,
I'm still checking, I just wanted to add:

Long answer, you cannot use those overloads in VB.NET, as the CLS (Common
Language System) which VB.NET adhers to, does not allow overloading on ByVal
& ByRef, as its ambiguous in languages that do not require ByRef (ref in C#)
on the method calls themselves. VB.NET only allows ByRef on the method
declaration.

I'll do some more checking if there is an alternative within VB.NET that you
can use, or you will have to use C#.

Hope this helps

Thanks Jay.

I ended up using the one with the x and y and no DrawTextFormat.

Thanks so much for taking the time.
