Hi,

I've been looking for like 2 hours for a method or anything that reads the text which is typed in a textbox.

I don't really know much about buttons and textfields. I usually work with the console.

Can anyone tell me how to read in text from a textbox plz?

Thanks in advance!

Hi Tamimi,

That worked! Thank you!

I declared readIn to read what is typed in the textbox like this:

string readIn = this.texBox1.Text;

And attaching it to the eventhandler like this:

readIn += new KeyEventHandler(texBox1_KeyPress);

It gives me the error:

No overload for 'texBox1_KeyPress' matches delegate 'System.Windows.Forms.KeyEventHandler'

What am i doing wrong?

hi could you give more details about what you are trying to do ??
if simply you want the text in a textbox the .Text property its enough
and no need to attaching anything.

what exactly you want to do ??

Hi,

I want to accept only 0, 1, 2 .... 9 as input. In order to do this, i have to attach texbBox1.Text to the keypressed handler.

But i got it fixed now,

Thank you!

hi
is there any wrong with this:
private void textBox1_KeyPress(object sender,
System.Windows.Forms.KeyPressEventArgs e) { int intKeyValue = (int)e.KeyChar; if (((intKeyValue<48 || intKeyValue>57 ) && intKeyValue!=46)) { e.Handled = true; } }

Hi Tamimi,

There is nothing wrong with that method.

In fact, thats the eventhandler i was trying to attach 'readIn' to.

If a key is pressed 'readIn' will call that eventhandler to check if its a valid one.

Sorry for the confusion Tamimi!

Hi Tamimi,

Thats exactly what i meant. But i fixed that half an hour ago Smile | :)

I do have another question...

If i want to get everything between 2 chars, how would i do that?

Example:

[1]

[12]

[123]

How would i get everything between the '[ ]' chars?

Substring wont help, coz the characters inside the [] can be sometimes 1, 3 or more.

Thanks in advance!

hi try this:

int intStartIndex = textBox1.Text.IndexOf("[") + 1;
int intEndIndex = textBox1.Text.IndexOf("]") - 1;
string strBetween = textBox1.Text.Substring(intStartIndex,intEndIndex);

but you should be sure that the chars "[" and "]" are exists if not you will get an error index or something like this

You could also try using the textchanged event of the textbox.

He who laughs last is a bit on the slow side

Hi,
I have a radio button on my windows form and I want this to be databound to a binding source.
Ok, now it is very easy to set the CHECK State of the radio button to bound to a BIT data type of SQL. But what if I want to add some custom code for the CHECK STATE and the custom code uses the other type of data field from the SQL ? IS is possible ?

Example : I may have a varchar field in SQL which is named "fieldType". Now I want to add the following constraint,

Databound CheckState should be checked if(fieldType == "abc")
otherwise CheckState should be non Checked.

Thanks and regards

and call the fuction...
eg,

[DllImport("kernel32")]
private static extern int InitiateSystemShutdown(,,,);
