Do you know how to use the data in “textbox1.Text” (Form1) in a method on another form (Form2) all within the same namespace???
That's only a matter of public/protected/private member visibility.

Using C# in a Winform, I have a tab control with 2 tabs... I added methods for Enter and Leave events for tabpage1, but the events never fire when I switch tabs... breakpoints in these methods are never hit...
what am I forgetting or doing wrong...???
thanks.

The Enter and Leave events are for the TabPage not the TabControl. Once you switch Tabs if you click in the TabPage your event will fire. If you want to do something when the TabControl switches pages it's best to put the code in the SelectedIndexChanged event of the TabControl.
Hope that helps.

Use toolbox to drop a tab control onto the form;
use the tab properties menu (Tab Pages - collection) to create one, or more tab pages and their labels;
Right click in the whichever is topmost in the control - you will note that right clicking the mouse within the tab control's page(s) will bring up the properties (or events) menu for the Tab pages - can't set event handlers here - what you have to do is to then left click on one of the tabs - you will see that the properties (or events) menu for the Tab Control is now displayed (see note 1 below). You can now create event handlers for "Enter" and "Selected Index Changed" to give you the notifications you will most likely want to use use in your code - the "Enter" event occurs when the tab control (regardless of whichever page is topmost) receives the focus; the "Selected Index Changed" event occurs when you click on a tab different than the one that is currently topmost.
Note 1: If you are displaying a Tab Page's properties (or events) menu (say for page 2) and you then left click on the page 2 tab to switch to the Tab Control menus you may find that it won't switch - have no fear, simply left click on a different tab. If you have a one tab control then click on the blank space immediately to the right of the tab.
A VERY simple example of a do-nothing "Selected Index Changed" event handler is:
private void tabControl1_SelectedIndexChanged(object sender, System.EventArgs e) {
int index=tabControl1.SelectedIndex; // Tab Control's tab index (0 relative)
int tabIndex=tabControl1.TabIndex; // KB tab-key order
string str = String.Format("tabControl2_SelectedIndexChanged selectedIndex={0} tabIndex={1}", index,tabIndex);
MessageBox.Show(str);
}
Hope this helps.

Are there any C# classes that support compressing/decompressing streams or even strings? One would think that there would be, given .NET's use on the Internet, and with XML, and SOAP especially, creating large objects with little effort at all.

|
|

Here is a compression library for C#: SharpZipLib[^].
Hope this helps,

I've recently made a small, simple C# windows application that shows what week we currently are in, and some other things as well. The executeable file is apx 13 kBytes, and when I execute the program it takes, all according to Task Manager, 23MB!!! How and why?! If I show the application's GUI and minimizes the application, the memory consumption goes down to < 1MB. The application is in release mode.

Your 5kb, plus the frameworks VM memory. Fraknly I dont understand why everyone is complaining at less that $1 for 10Mb...

Well, when my small traybar-based application that shows what week it is requires more memory than say one instance of Internet Exlorer or Opera 7, then I want to complain a little bit 
|

One thing that you can do to reduce the memory footprint of your application at runtime is to remove any unused assembly references. For instance, all GUI applications seem to come complete with a using System.Xml statement along with a matching reference to the System.Xml.DLL assembly. That's fine if you are doing xml stuff, but if you aren't then the extra assembly is just taking up space...  Try it, you'll see what I mean.

Hi. Let's say you saw a code like this:
Qwe.Asd.Zxc;
As far as I know this Zxc could be:
1. Name of a nested class
2. Property
3. Static member/function
What I'd like to ask is, can it be anything else?
|
|
|
|
|
it could also be a field.

AFAIK:
This is not a valid C# syntax. The problem is on ';'
If you have the following:
Qwe.Asd.Zxc
Then it could be (1) and (2), a field, a type specification (for casting), or a const, and (3) and a non-static method in the context of a delegate instatiation.
If you have the following:
Qwe.Asd.Zxc(
Then it could only be (3).

It can technically be anything. It all depends on what Qwe and Asd are. But it could be anything from a Namespace to a field.

Hi all

Hope I have not misread what you are after, as what I think you are after is really easy
On you form you have a label called lblMessage that says "hello" and a button called butChange
add the method
private void butChange_Click(object sender, System.EventArgs e)
{
lblMessage.Text = "new text" ;
}
hope this helps and sorry if i missed the point ![Beer | [beer]](https://codeproject.freetls.fastly.net/script/Forums/Images/beer.gif)

When you have executed your applications code within the .NET IDE why is it that the properties window cannot be accessed until the code has been closed and re-opened within the IDE?
Has anyone come accross a solution to enable you to see the properties window again even after executing the code?

Hit F4 or go to View|Properties Window

No, this won't help. It's a very annoying bug on the VS.NET IDE, and MS recognized it on their top VS.NET bugs page, and only occurs when the Properties Window is at some specific positions.

That normally ends up with VS.NET running into some infinite loop, having to close it via the TaskManager.
