one line assignment [solved]

halu,

i'm kinda confuse about one line initialization... this gives me a "not i want" output...

VB Code:

cmbCategoryStatus.Text = cmbMakersStatus.Text = String.Empty

is there a bug? i really don't know... it doesn't clear at all. it just clears the cmbMakersStatus and put "True" to cmbCategoryStatus.Text. is this supported in VB.NET -- the one line initialization?

it also has no effect with integers either... like

VB Code:

i=j=0

just want to clarify if VB supports this kind of initialization...

thanx

halu,

i guess VB.net doesn't support what i want. i queried this on msdn abot operators

Used to assign a value to a variable or property.

variable = value
Parts
variable
Any variable or any writable property.
value
Any literal, constant, or expression.
Remarks
The name on the left side of the equal sign can be a simple scalar variable, a property, or an element of an array. Properties on the left side of the equal sign can only be those properties that are writable at run time. When used, the value on the right side of the equation is assigned to the variable on the left side of the equation.

Example
This example demonstrates use of the assignment operator. The value on the right side of the expression is assigned to the variable on the left side of the expression.

Dim myInt as Integer
Dim myString as String
Dim myButton as System.Windows.Forms.Button
Dim myObject as Object
myInt = 42
myString = "This is an example of a string literal"
myButton = New System.Windows.Forms.Button()
myObject = myInt
myObject = myString
myObject = myButton

examples only categorize about one variable to be assigned to one variable... i don't know... some ideas are still welcome...

thanx

Neither of those lines initialize anything they just assign things. An example of one line initializing would be:

VB Code:

Dim str As String="I'm Initialized!"
 
'instead of
Dim str As String
str="I'm Initialized!"

What is it you are trying to do?

ooops, sorry wrong word used... what i meant is assignment. is there any way of one assignment...

like the one i post earlier... i=j=0

sorry... is this supported in VB? like the ones in java or c...

thanx very much...

No I'm afraid it's not. What is the purpose of that in Java? OR is it just a handy shortcut?

sort of... i'm a newbie though. hehe. but i encounter this in java or c. like assignment of i and j on a single line. we would normally do that. like i=j=0. just wondering if it's possible in vb but thanx for the information. i even search msdn and no luck at all. i would like to assign two combo boxes' text a string empty. :)

i guess i found the answer right now. thanx Edneeis...

thanx times ten to the power of forever...

C# perfectly accept this kind of assignment .

But if you want to set any property for similar controls on your form , then use this code for example to clear the text in all the comboboxes on your form .

VB Code:

Dim CBox As Control
        For Each CBox In Me.Controls
            If TypeOf CBox Is ComboBox Then
              CBox.Text = String.Empty
   End If
Next

halu,

thanx, so much... i tried that... that works man. very well...

thanx times ten to the power of forever...

I don't think you can do that in C#. He means:

VB Code:

TextBox1.Text=TextBox2.Text=String.Empty

Did you try it Ed ?;)

See here :

And that assigns String.Empty to both textboxes? If so that's cool I didn't realize you could do that in C#. Right on Pirate!

I love C#. :)

It compiles but doesn't work as expected in VB. It is interepted as textBox1.Text=(TextBox2.Text=String.Empty) and makes the text for textbox1 =False.

i tried doing C# the first time of my life. gosh.... i'm kinda newbie though... it works with me

Code:

---

                private void button1_Click(object sender, System.EventArgs e)
                {
                        textBox1.Text=textBox2.Text=string.Empty;
                }

thanx to all... hehehe..

This proves C# isn't VB , It's the little son of C/C++ . :D .....;)

I read that C# was really intended to help people adapt from Java to .NET so really I guess it makes sense that it can be done there since it can be dnoe in Java.

Just my 2 cents.

Could be true but I'd stop at this point and agrue no more since this topic would drive this thread crazy lol . :)

yezzz. kinda wondering that before but just asking if it's in VB. so now, i learn something... i tried C, Java before but just basics. anywayz, thanx to all of you guys... thank you thank you...

that's times ten to the power of forever... :bigyello:
