I'm not quite sure what you're going for here.
Calling your classes "Form" and "Button" doesn't make a whole lot of sense in a non-GUI app. Not to mention the idea of "clicking" something is a GUI concept.
That said, there's nothing in your Button class that actually fires the event.
You can add a public method, such as PerformClick() that call a protected method, such as OnClick(), which then fires the event.
public void PerformClick(){<br />
this.OnClick();<br />
}<br />
protected void OnClick(){<br />
if(Click != null){ Click(); }<br />
}
Then from the Form class:
button1.PerformClick() will cause the event to be fired.

Sorry Charlie I got disconnected. I wish you Merry Christmas and a Very Happy New Year in advance. But I intend to target the Console. This is a console application and not a windows application. I want to display the line "Button was clicked" on the Console. But I still want to use the event and delegate etc. i.e. My event will get fired when I call it from the Main. i.e. I will create a Form Object from Main to call the form class and I will type Form.Button.click. this is when the event will be fired.

Does anybody know how can I determine what keys are being pressed within other applications? For example I want to know everything typed in Macromedi Flash environment...
I greatly appreciate your answers

I've setup a browser in an application similar to what has been explained in this article, when I browse around to one or two different HTML files and then go to a powerpoint document things work fine. If I check out more than one or two HTML files and then go to a powerpoint document, I'm able to click and advance one slide, but further mouse clicks do nothing, not even right clicking. At this point I'm able to use the mouse wheel or the scrollbar on the browser to advance, then everything works fine again.
I've been searching on msdn for any info on using powerpoint within the browser control but haven't been able to find anything yet.

My web calendar control is correctly populating each calendar cell with the course and time as programmed. Problem: it's creating twins! Each listing is created twice. Stepping through the code revealed that each calendar day is being rendered twice. What do I need to do to nonduplicated entries?
Code Follows:
protected void C1DayRender(object sender, DayRenderEventArgs e)
{
if(courseTable.Rows.Count>0)
{
CalendarDay d = ((DayRenderEventArgs)e).Day;
TableCell c = ((DayRenderEventArgs)e).Cell;
DateTime tempDate;
foreach(DataRow dr in courseTable.Rows)
{
tempDate = (DateTime)dr["sDate"];
if(tempDate.ToShortDateString() == d.Date.ToShortDateString())
{
string s1 = "
" + dr["CourseName"] + " " + tempDate.ToShortTimeString();
c.Controls.Add(new LiteralControl(hypRegister.Text = s1));
}
}
}
}
I'm on a crunch deadline, and I think I am just missing a piece of code here to get this function to move to the next date after grabbing any matches in the container.
Thanks, Sally Lay

Solved the problem. This calendar does more than reflect a schedule; it is also a registration tool. Removing the "this.Calendar1 += new Calendar1.DayRender;" line in the generated web designer form code made each day render itself only once. Thanks, Sally

I have a function that needs to accept a string and append it to another string. I initially implemented it like this:
private String big = "";
...
private void OnIncoming( String small )
{
big += small;
big += "\r\n";
}However this seems to be extremely inefficient. Receiving about 300K of text (which happens to come from the net) in small amounts takes about 1 minute. However, if I simply comment out the contents of OnIncoming (the two += lines) it takes about 5 seconds. So it appears the string concatenation is causing the problem.
How can I improve this? I need to take a bunch of little strings (one at a time), and concatenate them into a larger string. Any suggestions as to what would be the most efficient way to do this in C#?
Thanks in advance for any suggestions, ideas, or assistance!

You should use String.Concat for up to 4 string parameters, String.Format if you can format your string, or - which can be used for all - a StringBuilder (which String.Format uses internally).
Also, keep in mind that string are immutable while the StringBuilder is not (meaning it can actually grow). When you concatenate strings, the CLR must get the length of both strings, create a new string of the total length, then copy each character from both strings. You're right - it is very inefficient. The methods and class above will help you (and are nice for formatting and what-not, too).

Everyone, I'm hoping to call an unmanaged C/C++ function within a DLL directly from a C# class without having to bother with a managedC++ class as proxy. However, the DLL function includes the MFC CString in its prototype, so I'm thinking that perhaps I'm going to need to.
[DllImport( @"C:\Program Files\MyCompany\MyDLL.dll", CharSet = CharSet.Ansi)]
public static extern IntPtr MyFunction(CString arg1, CString arg2);
I understand that the InteropServices will likely be involved, and I'm about to do
my homework so see what needs to be done, but if anyone knows the answers, then
feel free to fill me in.
Best,
Jerry

Correct me if I'm wrong, but aren't CString's Unicode when UNICODE is defined (for applicable OS's)? If so, you should be using CharSet.Auto.
Also, remember that CStr is a wrapper, where the string is actually stored in m_str (or something like that), so you'd probably have to create a related structure and marshal to that struct. In that case, place the CharSet=CharSet.Auto in the StructLayoutAttribute for the struct.
I wish I could tell you more, but it's been a while since I worked with MFC and, believe it or not, CString doesn't show up in the class list!

Is it possible to add a button to Internet Explorer's main toolbar (next to the "History"-button)?

Not right next to the History button, no, but you can find information about adding buttons after the separator to the right of the History button here: Adding Toolbar Buttons[^].
Also, this isn't really the forum for this question.

Is there a way that I can create a copy of a textbox out of a TabPage and insert it into another TabPage. The way I've been trying is to add() the TextBox to the second TabPage but this removes it from the first.
I would really like for it to call the same TextChanged() function.
Any suggestions?
Thanks,
Matt

Point both textboxes at the same TextChanged handler

Mark's idea is a good one. I just wanted to add that a control can only have one parent. This is pretty much universal and goes down to the Windows Common Controls that pretty much each control in System.Windows.Forms wraps.

I have a datagrid and I want the data displayed and allow the user to select a record. But I don't want the blank last row displayed. I don't want them to be able to enter new data in this datagrid. This one is for selecting a record only.
Thanks for any help

|

append in your init :
MyDataGrid.ReadOnly = true;
|
|
|
|

Sorry, I goofed on the problem description. I want to be able to type into the existing populated grid rows (to update them) but not have the blank new record entry at the bottom
Thanks for your help
