There is a way to make custom controls with custom properties that is much cleaner than this, but it requires more code.
Google talk doesn't seem hard to make, with exception of the semitransparent shadow if this shadow is not caused by the operating system.

Oh.. i am extremely sorry....
After reading your reply and sending my reply, i made a different form and created a button to help it minimize and also added code to help it move around.
But this one is working fine...
Seems that there is something wrong with my code.
I'll look into it and let you know whatever the problem was.
Thanks a lot man.

Hi
This question is related to printing in .NET winform application, I am working on a wizard kind of application (in.NET using C# language) where in user will be guided through a set of win forms that collects user response for a series of questions (and stores/saves as a file in a srialized format).
I am at a stage where in i have to implement the "print and print preview" functionality for this application, Could you please suggest what is the best method to accomplish this task?
Tricky bit for me is - wizard/questionnaire contains (at some stage) a list view that will have entries which opens into child windows where the detailed information is displayed.(for eg, if the wizard collects information about a student, at some stage it has to provide in a list view, number of subjects he/she enroled into and upon clicking it opens a child window with details of subject/enrolment).
Your help in any form is greately appreciated!! Sorry if i haven't explained the problem clearly!!!
Thanks
Sr

Hi,
I'm no expert in this field, but take a look at code based security. By applying 'evidence' to your assemblies (or somewhere) you can control what they do. This is the mechanism used to stop an untrusted control running in IE on a local user's machine maliciously damaging files etc.

Rob Philpott.

I need to add online help functionality in my project(.Net), how to do that?

I extend a textbox for keypress event.
a form includes one extended textbox and a button which is accept button of form.
But when after editing text when u press Enter key , doesnt raise button_click event. How can pass this event to FORM when user press ENTER key after edit text.
|
|
|
|
|
if your case what i understand that after the user enters or modify the text he/she will press enter and the form should the run the code for that button .
so Simply select the form in the design Area and click F4 for properties the at go to Accept Button And choose your button.
as simple as that if this was your case .

Make sure in the Form properties the property KeyPreview is set to true.
of if you can't find it there go to where the Form properties are initialized and put this code there:
this.KeyPreview = true;
//"this" refers to the Form
//or
KeyPreview = true;
//but make sure the code is in the Form class
//otherwise you'll get an error

You got me wrong
Form has a button and ExtendedTextbox textBox
Button is already accept button of Form
ExtendedTextbox has keypress event to control entry ,So if u press ENTER, this event handles enter key.
|
|
|
|
|
I understand that, but you need to have KeyPreview = true; to be able to assign the AcceptButton property to a button for it to work without any extra code. (If the KeyPreview property is set to false, your case will only work if the only control on the Form is the button.)
This is part of the code and it doesn't include the Form initialization where you need to put KeyPreview = true;
This is all you need to be able to let's say write something in a textfield, press ENTER and even if your text still has focus it will work.
But if you don't have the KeyPreview set to true, it will not.

Im having trouble with a Windows application .......
When i run the Application in windows XP NO PROBLEMS
But when i run the APPLICATION ON WINDOWS2000 SP4 i dont get the same results as in XP
although all the nessecary Prerequisites are all installed (MDAC2.8,.NET Framework 2,Windows Installer 3)
The Application Opens up an excel file and read the data to a dataset and then copies one column that a user selects to an arraylist, then Open another excel file and also read the data to the dataset and copies the selected cloumn to another ArrayList and then compares the Arraylist from the first file with the arraylist from the second file and REPORTS in which rows there have been match's ........
so when i run the Application in the XP i GET about 342 Match's but in Windows2000 I GET ONLY 10 MATCHS
i dont know how the Application is Affected by the OS And HOW TO SOLVE THIS !!!!!!!!!

following is the default procedure for calling event
this.button1.Click += new System.EventHandler(this.button1_Click);
private void button1_Click(object sender, System.EventArgs e)
{
}
Now what i want the following
this.button1.Click += new System.EventHandler(this.demo);
private int demo()
{
MessageBox.Show("Called");
return;
}
demo is the function which i have to called. which is returning value.
but when i do with above code it gives me error " does not match with delegate"
how can i call my own function instead of system defined. and how can i handle the returning value

Events by convention take two parameters, object sender and System.EventArgs e. The sender tells you from where the event has been fired, and the eventargs is a reference to a class where you can define your entry and exit parameters for the event. You can derive a new class from EventArgs for this where necessary, although in your example you're in the realm where everything has been defined for you, so you really shouldn't be doing this.
Alternatively, if you want to break with convention and best practices you can define your own events which don't follow this pattern, but you won't be able to attach these to things like the button click event, as it expects this sender/arguments prototype.
You can do this by defining a delegate which describes your callback prototype, and then creating an event of type said delegate.
I'd stick with convention if I were you...

Rob Philpott.

Alternatively you can do:
this.button1.Click += new System.EventHandler(this.button1_Click);
private void button1_Click(object sender, System.EventArgs e)
{
demo();
}
private int demo()
{
MessageBox.Show("Called");
return;
}
//OR
this.button1.Click += new System.EventHandler(this.button1_Click);
private void button1_Click(object sender, System.EventArgs e)
{
MessageBox.Show("Called");
return;
}

I have an application with a form and a class.
The form has a textbox, and it creates an instance of the class when it loads.
In the class there is a thread that, let's say, calculates a number, and wants to display this number in the textbox on the form.
How can I do this?
(I can't seem to get access to the textbox from the class)
|
|

Your textbox belongs to a class as well, the form class and by default this textbox has private access so you can't get at it.
Take a step back though, what you are trying to do here is tightly couple the GUI to the logic. You end up with a calculation class which can only be used in conjunction with a particular form. You should call out from the form class to the calculation class, collect the answer in the form class and then assign it to the textbox. The calculation class should be made as reusable as possible and not have a clue about the GUI of the application it is to be used in.
You need to be particularly careful if using worker threads - these should not access GUI components without a thread switch provided by BeginInvoke.

Rob Philpott.
