o2flameuser · May 22, 2009

1 ) think about 3 textbox
i wanna to make
when i enter first textbox a number and to a second a number
for example 3 and 5 after i wanna to add these number automatically by without pressing a button and program put to the third textbox 8
txb1 3
txb2 5
result txb3 8
how is this possible ?

2) i save data s from my program to a word file for example logs.txt
with
fileopen(c1,"logs.txt",cwrite)
filewrite(c1,textbox1.text) which is going to save the text that what i enter to it

actually the problem is when i to try open that logs.txt while running the program device gives errors

but when i open the logs.txt after exit my program it opens it and i can see the contents

but i wanna to open it while program is running with a shell command

how is possible ?

use the Key Press event...
From the help file:

Occurs when a control has the focus and the user presses on a key.
Forms (unlike other controls) can receive one of the SpecialKeys constants and can handle the Hardware direction keys.
Syntax: Sub ControlName_KeyPress (key)
key is the key value that was pressed.

For Forms: Sub ControlName_KeyPress (SpecialKey)
SpecialKey can be one of:
cDownKey
cLeftKey
cMiddleKey
cRightKey
cUpKey

Wich mean that on this event, you can check if the textbox value is valid or not, and then execute some other thing..

o2flameuser · May 22, 2009

for example can you give me an axample please ?

Cableguy · May 22, 2009

The best event to use would be the OnTxtChanged event, but it is only available on ControlsEx from Agraham...
This is untested code and may not even work, but should give you an idea....

Sub TextBox1_KeyPress (SpecialKey) This is the key(s) you want to test
Textbox3.text=Textbox1.text+textbox2.text
End sub

o2flameuser · May 22, 2009

my friend it is givin an error when i try to enter eny value for textbox1
the error as follows
An error occurred on sub main.textbox1_keypress.

error description:
FormatException
Continue ?

Cableguy · May 22, 2009

as I said that was un tested code, an may not suite your needs...
explore the help file a bit, and you will find lots of examples that may sed some light...since you are not yet a registered b4p user, you cannot download the ControlsEX Dll, that would for sure suite your needs.

o2flameuser · May 22, 2009

i explored the manual but cant find
any suggestions are wellcome

Cableguy · May 22, 2009

Another aproach would be to add a timer, and set it to 2 or 3 seconds interval, then, of every Focus event of the textboxes, start the timer...On the timer tick event, check the values of the texboxes and do whatever maths you need

If you enter only ONE digit into TextBox2, this code works:

B4X:

[SIZE=2][FONT=Courier New][COLOR=#0000ff][SIZE=2][FONT=Courier New][COLOR=#0000ff][SIZE=2][FONT=Courier New][COLOR=#0000ff]Sub [/COLOR][/FONT][/SIZE][/COLOR][/FONT][/SIZE][/COLOR][/FONT][/SIZE][FONT=Courier New][SIZE=2][FONT=Courier New][SIZE=2]TextBox2_KeyPress(key)[/SIZE][/FONT]

[/COLOR][/SIZE][/FONT][/COLOR][/SIZE][/FONT]

If you want to enter a number with more than one digit you need to use the Door library to use the TextChanged event like:

I don't understand exactly what you want to do with your file.
Why do you want to open it with a Shell command and with what program.
You can open a file within the program with FileOpen(c1,"logs.txt",cRead)

Do you want to use a Word file *.doc or just a simple text *.txt file.

In The code you show there is no FileClose(c1) ?

Do you have some sample code we could look at ? It's much easyer for us to look at the complete code rather than on some sub parts.

Best regards.

o2flameuser · May 22, 2009

tnx for all your reply
but i solved it
gotfocus did the work by this type

firstly i set to 3 textbox as a variable 0
then

Sub TextBox1_gotfocus
TextBox3.Text=TextBox1.Text+TextBox2.Text
End Sub

Sub TextBox2_gotfocus
TextBox3.Text=TextBox1.Text+TextBox2.Text
End Sub

for each textbox 1 gotfocus

and thats is the what i want

tested and working

but could not find a soln for my second problem

in fact the program does not allow me to open my logs.txt file (that is my database) while running but when i exit my program i can open it with the pocketword (logs.txt) and see my datas

any suggestion to solve this problem ?

o2flameuser · May 22, 2009

yes i want to my file show on pocket word
i include fileclose(c1) but it doesnot open when the program run
any help ?

klaus · May 22, 2009

You could also use the LoasFocus event.

I made the proposal with the Door library because you didn't want another mouseclick to transfer the result into TextBox3. But in your example, you need a mouseclick to transfer it, like clicking on a button would do the same, and from a user's point of view probably more obvious, but that is just a personal feeling.

For you saving problem, I still don't really understand what exactly you want to do !
If you want to save and read the same file at the same time it's not possible. But instead of saving your intermediate data and or results in a file you could save them in array, in the program, and save the array when you quit the program. But you have all your data available in the array while the program is running. When starting the program you could even read the file back with previous data into the array and add the new ones and save again at the end.
But for me it's still not clear what you want to save and when and what you want to have back, when and for what. So it's difficult to give concrete advices.

Best regards.

and here is my complete prog

Cableguy · May 23, 2009

You shouldn't use FileOpen in globals, it is not an elegant way of doing things...
The globals shoul be used to just that, global variables...(This is my Opinion...)
You should use it before any fileWrite statement...like this:

Textbox11.Text = 0
Textbox12.Text = 0
Textbox13.Text = 0
Textbox14.Text = 0
Textbox15.Text = 0
Textbox16.Text = 0
FileClose(c1) just to make sure this conection is closed
FileOpen (c1,"logs.txt",cWrite)
FileWrite (c1,textbox1.Text&cTab&textbox2.Text&cTab&textbox3 .Text&cTab&textbox4.Text&cTab&textbox5.Text&cTab&t extbox6.Text)

FileWrite (c1,textbox21.Text&cTab&textbox22.Text&cTab&textbo x23.Text&cTab&textbox24.Text&cTab&textbox25.Text&c Tab&textbox26.Text)
FleClose(c1) Now Close it
Goto there:
HERE:
Msgbox ("ERRORS FOUND!!! POT IS NOT CORRECT PLEASE CORRECT IT")

This way the file is released and can be opened from outside the app

klaus · May 23, 2009

Here you have a somewhat modified program with storing the data in array variables.
I have changed the control names to use selfexplaining names, for example 'txtDate' says more than 'TextBox30'.
I have added some more advanced keywords to show you what can be done with Basic4PPC.
I have added a save button to save the whole dada at once, with a comma as a separator character and with a csv extension. This file could be directly improted into a Table control.
You could show your data in a Table control.

Best regards.
