vb mass math calculation

[dertsap]

i 'm new to this vb stuff , ive been working on a small program that works along side of inkscape , i import a bitmap into inkscape ,trace it and save it as a latex file , then i copy and paste the latex file into my program and it produces gcode , the problem i am facing is i have no control over the dimensions inkscape saves the file as , so what i need to do is a mass division of all the numbers so that i can scale down the gcode to the size that i want to be cutting at
is it possible to do this , i have searched the net over and over again but i cant find anything showing how to divide all the numbers by 100 or so .

so far the code simulates well but my machine isn't big enough to cut something that is 1024" x 780"

any input would be greatly appreciated

Are you running vb.net?

Give me a few min., I'll throw something together.

ah
your a good Man !
ive been beating my head against the keyboard trying to figure this out

i think its going to be a great lil app once its all completed , ive just got to get past the learning curves

Well I can't find the source I have, I had a similar project a while back, I know I have it I just can't find it on my pc. I've got about 1000 diff. files that are all source code for vb.net 03 & 05.

I did post a sample code of how to use "Replace" (vb.net 2005), it should work with your 2008.

I'll keep looking for the code I planned on posting.

As far as what your trying to do, will your file have numbers & letters (X,Y,Z)?

the numbers will have have xyz , they start off as line to curve to and i convert them overto g1 xyz , heres more or less what ive done to this point ,ive included a test latex file , i open the latex file and copy and paste it into the converter , i still need to figure out how to deal with the curves , right now they are g1 moves

This might help with the division & decimal.

This code will also Format the numbers so you can specify how many decimal places in each direction (left/right) you want the numbers to be, so you don't end up with numbers like 123.123456789


Add a button & a textbox to a form, then double click the button while in the designer, that will open up a new click event for the button in the text editor of vb.net, then copy & paste the code below into that new click event that vb.net created, then run your program & click the button.





Dim D1, D2 As Decimal
D1 = 10
D2 = 0.7

TextBox1.Text = Format(Decimal.Divide(D1, D2), "##0.000")

The first thing that needs to be done in the sample (.tex) that you posted is to strip all the stuff you don't need down to only the stuff you can use in your g-code.

i strip down some of the stuff within the converter ,but i still have a few more garbage lines to pull out of the generated gcode ,im not sure how to outright delete them so ive replaced them with a line space , which i will need to figure out how to close them up at a later time , i still need to add a textbox for z moves and stuff ,
its this mass division of all the numbers that has me stumped

Try this, you need a richtextbox & a button. Put this code in the button click event, run your program, then enter a number in the richtextbox with decimal (123.123). Then press the button.

Your answer should be 24.6246 at the top of your form/project.

Dim d2 As Double d2 = richtextbox1.Text d2 = d2 / 5 Me.Text = (d2)

I forgot to format the number.

Dim d2 As Double d2 = richtextbox1.Text d2 = d2 / 5 Me.Text = Format(d2, "##0.000")
