I want to be able to say
DIM edit as QEDIT
form etc
EDIT parent..... etc etc
IF edit > 6 then showmessage "must be below 6"
if EDIT <0 then etc......
I only only get if statements to work as a string but this is no good, you can imagine the amount of IF statements I would require. I can post source code if required
Thanks for any help. | 2. Re: Integers and Qedit #983 Posted by: 2003-06-10 07:06:02 | use
value = VAL(Qedit.Text)
Qedits contain text, VAL turns the text into a value.
To put a value in a Qedit use
Qedit.text = STR$(value) | 3. Re: Integers and Qedit #989 Posted by: 2003-06-12 22:56:44 | it still dosn't work, this is my section of that code:
dim stylewidthnumber as integer.......................
stylewidthnumber=Val(sylewidthedit.Text)
stylewidthedit.text = STR$(stylewidthnumber)
if stylewidthnumber <1 then showmessage = "must be greater 0" | 4. Re: Integers and Qedit #990 Posted by: 2003-06-12 23:01:21 | the line
stylewidthnumber=Val(sylewidthedit.Text)
should be
stylewidthnumber=Val(sTylewidthedit.Text)
I presume ?
| 5. Re: Integers and Qedit #991 Posted by: 2003-06-12 23:04:40 | And an integer is a whole number, a QEdit text could well have a fractional component. So maybe you need to use
stylewidthnumber = INT( Val(stylewidthedit.Text) )
Mind you, this does not round the number but cuts the decimal part off, so I'd use
stylewidthnumber = INT( Val(stylewidthedit.Text) + 0.44 )
| 6. Re: Integers and Qedit #992 Posted by: 2003-06-12 23:22:18 | Instead of using a shedload of IF's you could use CASE .... SELECT (see the Rapid Q documentation)
Alternatively use an array of texts to be displayed* and use the value to display the appropriate text, for example;
Qedit.Text = choice$( int( val( stylewidth.text ) + 0.44 ) )
Alternatively use a QComboBox instead of a QEdit, fill the box with the choices / texts. That works for choosing VALUES too, for example;
for x=1 to 7
a$ = " "+ Str$(x)
StyleBox.AddItems = a$
next x
Use value = StyleBox.ItemIndex + 1 (it starts counting at 0) to get the number of the item chosen
If you were clearer on what you are trying to do the answers you get
would be more appropriate :P
* set up the texts to be used at the very start of the program ...
Dim choice$(required number)
for x=0 to required number
read choice$(x)
next x
data "minimum value is 1 !","choice is number one","number 2"
etcetera
| 7. Re: Integers and Qedit #994 Posted by: 2003-06-13 00:45:51 | thanks, I am just making an HTML editor and I have a a bit where you can had a horizontal rule, I just need to make a maximum value as its designed for absolute bigeners of HTML.
Also I don't suppose you know how to get bold, italic and other information from the font dialogue box do you? so far I can only get font name, colour and size to work. Thanks | | Forum List • Thread List • Refresh • New Topic • Search • Previous • Next 1 |
