If Statement problem...

[Aziera]

Im really sad....because of the simple problem, i cannot move to the another doc....

im very new in this vb.net...so, im really hoping dat anybody out there will help me...

i make an entry form using txt box and date..
i need the user to key in the name of document,date and payment...
for the beginning, i list 10 entry...
my problem is, if the user only fill until the third textbox, then i print it, the value of the default date will be print also...

im using this statement:

if txtD1.text <> " " or txtP1.text <> 0 then
'print the name of document
'print the date selected
'print the payment
end if

but, i dont know y the compiler will ignore the txtD1.text that equal to blank, and then print the 3 item,,,the problem is with the default date..it will appear until the list of 10 eventhough i'm only insert 3 entry....

plzzzz....someone help me....
the date line is close but i'm stuck if the simple if statement....
i dont know to make it no print the default date....for information, i'm using datetime picker.....

if txtD1.text <> " " or txtP1.text <> 0 then
'print the name of document
'print the date selected
'print the payment
end if

I don't exactly understand what your asking for. But, if your testing for txtD1.text to be an empty string (i.e. "") then you need to type it like that, "", not " " (no space).

Right now if txtD1 doesn't contain anything, then your line:

txtD1.text <> " "

will evaluate to true because your asking if it's not equal to one space...

change it to:

txtD1.text <> ""

and try again.

np. You might also want to use trim:

txtD1.text.trim <> ""

to make sure that you account for someone putting just a space in there and not realizing it.

HI,

What's with the "or txtP1.text <> 0 then"???

What are you testing for - a zero value or the character 0?

[alextyx]

if txtD1.text <> " " or txtP1.text <> 0 then

In the above case you test a zero value

If you want to test a 0 character:

if txtD1.text <> " " or txtP1.text <> "0" then

Good job

HI,

"txtP1.text <> 0 then"

What I am trying to draw your attention to is that you are NOT testing for zero value. You are testing for the number 0. If an alphabetical letter or a null is in txtP1.Text, you will get a runtime error.

Hi, Taxes.....I agree perfectly with you.
I was not sufficiently care to view the entire question and I only was concentrated on to show the difference,in general, between with and without quotes, thinking it was the our friends Aziera's doubt.

well, i've learned a lot from here...

Special thanks to all of u for sharing ur precious knowledge!
