working with textbox in visualbasic 6.0

[dayalanstephen]

I have two textboxes, where i give input in one textbox and it reflects in another textbox. for eg., entering page numbers in the first textbox will be displayed as 1,2,3,4.... in the second textbox.Now if i want to delete a particular number how can i delete. Solution please

tough... you gave the example 1,2,3,4... it is fairly easy if you know that the string will be EXACTLY that format. im going to assume that, just so i can give a fairly easy solution.

i assume you ALREADY have something like this:
text1_change()
text2.text=text1.text
end sub

if we know that the "page numbers" are always going to be one digit numbers (like your example) then we can do this:
text1_change()
dim i as integer
const BadChr = "4" ' the page number you DONT want.
for i = 1 to len(text1.text) 'looks at each character individually
if mid(text1.text,i,1) <> badchr then text2.text = text2.text & mid(text1.text,i,1)
next i
end sub

input: "1,2,3,4,5,6,7"
output: "1,2,3,,5,6,7"

if you want to remove that extra comma, or have more than 1 digit numbers, or if the input could be a different format, i wish you would explain that in your question. but until people learn to explain there questions, i will answer them as they are written.

Thanks for your reply BSOB,
the input will be either 1 digit or 2 or 3 or more digit, which will in turn reflect in the second textbox, If i want to delete a particular number along with the comma by getting an input through a inputbox how should i write the program. Solution please.

Hi I'm afraid I don't know your solution, but I wonder, could I be cheeky? I am trying to write a program that has 17 text boxes on it, each being hidden until the appropriate button is pressed. I would like to be able to have input from the box I am using (i.e. January, Febuary, etc, put into another (hidden) text box automatically, similar, I think, to what you are doing. Is it possible to share some code? I am a complete beginner though.

steve, start your own thread AND please be more specific.

dayalanstephen,
thank you for being more specific.

dim Unwanted as string 'in general declarations for big scope
private sub ChangeUnwantedBtn_click() 'a button to change the unwanted number
Unwanted = inputbox("what number dont you want?")
end sub
private sub text1_change()
Dim CurrentNum as string 'the current number itis reading
Dim CurrentPosition as integer 'the position in the string that it is reading
do until currentposition = len(text1.text)+1
currentposition = currentposition + 1
if mid(text1.text,currentposition,1) = "," then
if val(currentnum) <> val(unwanted) then text2.text=text2.text & val(currentnum) & ", "
currentnum = ""
else
currentnum = currentnum & mid(text1.text,currentposition,1)
end if
loop
if val(currentnum) <> val(unwanted) then text2.text=text2.text & val(currentnum)
end sub


i think that will do it for you. could be typos and code has not been tested. on the "do" line, im not sure if you want the "+1" on the end or not, you will have to test that.

thanks for the reply bsob,
i tried with the codings which you gave, but it does not reflect the textbox2.
Also i want to know why you use text1.text coz i use an inputbox and that should directly reflect textbox2 where you have the numbers like 2,4,8,12,35,99,105 in textbox2. Through an inputbox i select the number that is unwanted as the same code which you have used
private sub ChangeUnwantedBtn_click() 'a button to change the unwanted number
Unwanted = inputbox("what number dont you want?")
end sub
but please tell me why you use text1_change( ) and please help me out line by line with comments what that particular line does. Please BSOB......

I assumed that your application would have one number you didnt want, and you would be putting in lots of data (into text1) without changing your unwanted number. That would allow you to type into text1 the text that you have and any time that you type, it will post that text (from text1 to text2) without the undesired number.

text1_change() will update text2 as often as you type anything into text1. that is why i used it.

from reading your question, i gather that your raw data is input into text1 and then you want the editted data (without undesired number) to appear in text2. is that correct?
ill do line by line help when i feel like i fully understand your question. use examples, use "what ifs" and try to give me as clear an idea as possible, thanks.
