tao opengl project error with texture loading using vb images

What do you guys make of this error?

Attachment 90579

Try putting a System. in front of it?

That fixed that error, so strange, how an earlier version of my work worked and it had compensated for this issue with name spaces, but i dont recall removing any namespaces to cause this error since then!

Any how i got another error right after i fixed taht error, could you have a look at this?

I went to line 190 of my code but i didnt see relevant errors, i even put a bullet point there to break the program before it got there but the error occured before then, i get the feeling line 190 is refering to the build file of my program, how do i access that if thats the case?

While im not a noob to opengl im a bit of a noob when it comes to vb, im usint tao.

Thanks for helping me, for some reason my project seems to work in another OS im running in a dual boot of the same machine, both running win 7 but here on the 64 bit os the project spits out all these errors while i have vb2010 express installed on both OS i dont see why i have problems with this version of vb2010 on the 64bit version of win7 but i guess thats a seperate issue. For example i dont have the above problem in the 32bit win7 version of vb2010 express, same project folder and files and everything! Im wondering if its because i have not properly set up resources links in this newer install of vb2010.

Look at that line specifically. It looks like you're doing a cast:

at Microsoft.VisualBasic.CompilerServices.Conversions.ToDouble(String Value, NumberFormatInfo NumberFormat)

Which is trying to convert a string (i'm guessing the text value of txtCylinderEmploymentPeople) which, at the time of the conversion, is blank:

Hence the error message.
