hello,i think this is just a simple question but im not really familiar with the basics of VB6.0 so i am asking it, can i ask how can i set integer value on text1.text without making the value visible on the textbox when i run the program? thanks

like text1.text = 1?

but when the program is ran it can't be seen that a number is on the textbox?

Use the tag property of the text box...

Good Luck

to make the TextBox Invisible use the below code.

Text1.Visible = False

You can set the value to TextBox which is not Visible.

Hope this Helps

Ahhh, I deciphered the question, which is
Keeping the textbox visible, can the contents of the box be invisible...

Yes, set the background and foreground color of the textbox the the same value.

uhm okay, here's the situation, i am making a program with 5 frames with 4x4 textboxes each, and 1 frame which is reserved for the output.. the user is required to input the angle to be converted and placed on textboxes on each frame. Or he can also just manually place numbers on the textboxes..

i am really sorry, i think you are having a hard time on understanding my program.. The problem is, when one frame with 4x4 textboxes are left unfilled by values, the error occurs.. That's why i am planning to make hidden values on textboxes so in case the user left no value on one frame, the program will not be affected by the error. I hope you can now understand T_T

how many input if requires the program? is the Textbox are trying to hide are those sum/products/diferrence/quotient that are require for final answer? if yes

you can try making some textboxes outside then set its visibility to false.
