View 3 RepliesMy project is using Visual Basic 2010. I have a pure text save file with the following format:
num_TEC|1
num_STR|0
num_PER|0
num_MEC|1
num_KNO|1
num_DEX|1
I'm trying to load the data by using the first column as the object name and the second as the value. I've had some success with the following (skipping some basic IO lines):
prop = FileReader.ReadLine().Split("|")
tempvar = prop(0)
If TypeName(Me.Controls(tempvar)) = "NumericUpDown" Then
Me.Controls(tempvar).Value = prop(1)
I have a problems with this because I have some objects in panels or group boxes and Me doesn't reach into them.
Is there a way to just strictly reference an object with a variable? I'd love to assign the first column into prop(0) and just say
if TypeName(object(prop(0))) = "NumericUpDown" then
object(prop(0)).Value = prop(1)

View 1 RepliesI'm trying to save a setting that keeps what background image I'm currently using.If it's an external file, there is no problem, i can just get the .location and set it in a String setting to store it.
But, if I want to store an image resource as a setting, how do i do it?I know i can store rawdata, like bitmap information, but then i can't set that type of data to the my.background.
I don't know if the question should be: "how do i reference resources", but the my.resources.resource.methodsList doesnt contain anything that seems to be of use.
