Why not pass in the ComboBox itself.?
void FillIn(string Tbl, string Fld, ComboBox comboBox)
{
ComboBoxCBDS.Clear();
ComboBoxCBDA.SelectCommand = new SqlCommand("Select * from " + Tbl + " Order By " + Fld, ItemsConn);
ComboBoxCBDA.Fill(ComboBoxCBDS, Tbl);
comboBox.DataSource = ComboBoxCBDS.Tables[Tbl];
comboBox.DisplayMember = Fld;
comboBox.ValueMember = Fld;
}
By the way, you should use parameterized queries instead of concatenating the query string. Take a look at this article here on CP: SQL Injection Attacks and Some Tips on How to Prevent Them[^]

Hi,
I have a form where I want to popup a small form (messagebox) where the user enters a value into a textbox on that popup form and that value is returned to the main form for processing.
I know how to write the code to do this with a showdialog etc but was wondering if anyone has come accross a control that can do this "out of the box" so to speak.
I would have thought the messagebox control could be used as a base for such a control but have no idea how to go about it.
Any suggestions.

No, you need to write a control to do this. The messagebox is not a suitable base, just create a new form.

i just answered a question similar to this.
if i've missunderstood u're question then forgive me.
the answer is:
declare a static variable :
public static int n;
and access, modify or whatever from form2 as: Form1.n =5;
hope this helps.

Yes, you've misunderstood. He wants to use a MessageBox as the base for his form.

Thanks for that - I'll work on it now.
I've never understood/used static so it's time I did

datetime n = form1.n;
-- Not Working : error on 'n'.
'System.Windows.Forms.Form' does not contain a definition for 'n'.
just have to define a variable 'int n' in form1, n try to access it in form2.
how? 
nekshan.

if you only need to pass the value of the variable 'n' to form2 then just pass the variable as an argument of the form2 constructor
eg. Form2 frm= new Form2(n);
if that value need to be modified and updated in form1 you could declare it as static
eg. public static int n;
and modify it in form2 as: Form1.n=5;
hope this helps.

The obvious way is to pass it in, as someone said. The drawback of using statics is, it means you can only have one instance of that form. The best way to communicate from form2 back to form1 is a delegate.

 why a delegate? why not a property?

I found a living worth working for, but haven't found work worth living for.

Loose coupling - So the forms don't have to know about each other.
|
|
|
|
|
As well as loose coupling, a delegate will allow a value to be sent between forms that are both active ( if form2 is modeless and form1 needs to update itself right away )

' define

bad idea, it's against incapsulation rules. You should use a property for that

And make the property read only, or you break encapsulation just the same

I tend to disagree.
Suppose I have a variable distance (integer)
A distance can never be smaller then 0.
If I make my variable public, you can set it to what integer you like even < 0.
With a property you could build in a check.
set{<br />
if(value >= 0){<br />
distance = value;<br />
}<br />
else{<br />
distance = 0;<br />
}<br />
}
|

you can write a property.
public DateTime returnN{<br />
get{<br />
return n;<br />
}<br />
}
if your object is still valid, you can get the value by doing datetime n = form1.returnN;
A static variable is not suitable for this and neither is making 'n' public in Form1.
good luck

hi!!
i had been refering to article 'passing values betn forms'.
I tried from it, but still i cant pass my variable from form1 to form2.
I m getting error on passing my variable to the other form's variable.
i have used the object approach from that article :
http://www.codeproject.com/useritems/pass_data_between_forms.asp
Objects of forms are created properly.
This i have written in form1 :
p = ((form1)log).n;
// log is object of form2.
//variable 'n' i have to bring from form2,which contains a date from query fired.
but i m getting error :
'Object reference not set to an instance of an object.'
It would be v.nice if u could help on it.
Thanx.

I already explained exactly why you are unable to access the member, in your previous thread about the same thing.
If you can't keep your question in one thread, at least read the replies you get in the threads.

Hi, I am writing an application that will use textbox's in specific locations on the design form which i want to use which will print onto a document. While i am new to the printing functions of C# (as in looked at them for the first time lasst night ) I do not seem to be able to find many useful resources on printing in C# and was hoping someone could recommend a good resource which could help. I have done the basic tutorials, printing etc but nothing seems to cover printing from text box's at specific locations. These locations will be fixed so if i could just specify these to the printing class that would be great to, but my question is how do i do this as the area's on the form's I wish to print to are fixed on the A4 paper?
Many thanks for any help or recomendations of where i can find help.
