You might want to look at this article, A Complete Read Only ComboBox[^]
Or search this site for read only comboboxes. This might help you and you won't have to worry about trapping mouse events.
Hope this helps some,

Hello my friend,
Just check "DropDownStyle" property of combobox.
Set the property to DropDownList.

Hi All, I am trying to figure out how to use a VScrollBar within a Panel and a series of textboxs. I have about 25 textbox within a Panel. I want to be able to scroll through the panel if the form is to small to see all the textbox. I tried putting a VScrollBar within the Panel but can't get it to scroll the contents of the panel. I can't use AutoScroll property coz I'm developing for Pocket PC. Dot Net Portal Framework don't have autoscroll property for panel. Can you please tell me how am I gonna change the panel visible area.
Thanks

Hi guys,
In C# how do I check if a table exists on SQL server 2000? If it doesn't exists then I am creating the tables but I would like to check first if the table exists.
Please help.

an easy way would be to use a try and catch and create the table. SQL wont overwrite the table thus if it exist your program will throw the exception which will be caught. Or you could use the following T-SQL
IF (SELECT count(name) FROM sysobjects WHERE type = 'U' and name = 'yourtable') > 0
BEGIN
Print 'Table Exists!!'
END
else Print 'Table Does not Exist!!'

Thanks for your help. I am using try/catch at the moment but in the future I would like to use your Select statement.
I have a question about the select statement, (name) would that be name of the field in the table, also what is type='U' also don't you need sqlconnection object to run the query?
Please advice.

Dont change the (name) part but change the part where I put "YourTable" that is where your table name goes. What it will do is count how many tables exist in sysobjects with your table name and if the count is greater than 0 than the table exists. "U" just means its only looking at the user tables and not the sql server tables.

And, yes you do need a your sql connection ect.

Hi, Im a first time poster long time user of the code project.
I am currently working on a web browser. I have release the beta 1 version (its called: T.I.B. [Beta 1])and people all over the place loved it especially the people that tested it at Cybershack Forums.
I am now making a beta 2 and i have failed many a time to figure out how to get the html source of a webpage to open in a notepad document (.txt) like Microsoft Internet Explorer or for it to open the html source in a richTextBox when the user wants to view the source.
Can somebody help me out here, can you make me a code that will open the html source from a web page in a web browser control that will open in a .txt document or in a richTextBox or even in a pop-up windows form.
P.S. If somebody does manage to help me out here, i will give them credit for their programming in the credits of the my web browser program as a sign of how grateful i am.

Why not combine these two? Create a windows form with a RichTextBox and assign the html source to its Text property.

You can invoke the View Source function in the AxWebBrowser object:
http://support.microsoft.com/?kbid=329014[^]
or you can do this your self by getting the source of the document, and writing it to a text file in your temp folder, then simply launch notepad with the filename as an parameter.

I still don't get it... perhaps somebody who gets it can make a demo project of this function, it would be good.

I am trying to write data to a textbox I have on a form (Form1) from a method in a class.
In my class I try writing -
public class NumberProcessing
{
public static void UpdateNumArray()
{
Form1.textBox1.text = "hello";
}
but the intellisense does not recognise anything past Form1.
Why can I only access textbox1 when in public partial class Form1 : Form ?
How can I access the textbox property of Form1 from other classes ?

Sorry, c# is not VB6 you need an object reference to Form1 in order to update it. If you insist on this pattern pass the reference to the form in the NumberProcessing contructor. However, I seriously recommend scrapping it and trying again. From what I see you are about to design something very unmaintainable.

Thanks for your reply. I am very new to C# coming from a C programming background.
I do not fully follow what you mean as I understand constructors to be used when creating an instance of a class (i.e an object) here I am using static type which can not be initialized. If possible could you give me a short example of what you mean?
Basically I want to know how I can get access to the textbox property from a class other than Form1?
Or do I / should I always make reference to to the textbox property from within the Form1 class?
Thanks in advance

class SomeLogicClass{
public static void DoSomething(Form form){
}
public static void DoSomething(Control control){
}
public static void RegisterForm(Form form){
}
}
Also, you can create a singleton class. There are a lot of options. However, the path you are taking I have seen before and it will cause problems in the future. Look for some samples in a c# book as a good guide.

Trying for a more helpful version of the comment you got...

Form1 is a class. You need to access an instance of the class to pass a value through. What you're trying to do is a VB6 hack.
The best way to do this is to create a delegate between the two classes. I assume delegates can be static, although I've never seen one. If not, you will need an instance of NumberProcessing inside Form1.
The other way to do it is to create a property on Form1 which sets the text of textbox1, and pass a reference to the Form1 instance that's in use to NumberProcessing. This is less of a hack than what you're doing, but not as nice as the delegate.
I trust the code you're showing is just pseudo code. There is no level on which textbox1 and form1 are acceptable variable names. Also, if your controls are public, change them to protected at least. That's just another poor design that you'll come to regret later.
