Resize Form To Resolution

[Drutchlin]

Wow it's been a year!

 

Sorry life has been very busy..anyhow I have almost no time in the past year to look into this code. I have fixed one little area that I came across..what happens if you have a label that is using Word wrapping?..so I re-thought the way I resized fonts in relation to the container control .. this code will still have issues at extremely high irregular resolutions ... and you should watch out for the text on cramped labels ... My solution to limited text space is somtimes I have to play with the Z order of a labeel as well as the length...meaning I might need to make the label longer ..and hide the extra length under adjacent controls..

having problem building the class file :(

 

Hie Drutchlin and all,

 

Hi, i have the problem as in the thread. I tried to build the class file using vs.net but having some errors (10 errors) : e.g.

" The type or namespace name 'Drawing' does not exist in the class or namespace 'System' (are you missing an assembly reference?) "

 

Can somebody help me with this problem? actually im developing using VB.NET. To convert this file class from C# to VB.NET, can someone show me the way or any tools to use ?

 

Much appreciation and thanks for replies and help. :-\

 

Steven,

VB.NET beginner!

Most likelly you don't have the System.Drawing reference.

Just go to the References and add it.

 

Alex :p
