Hello!
I have a panel with 2 buttons and it has to be possible for user, resize the buttons.
Do you have some tipps for me?

YEs, capture mouse movement when the button is down ( or whatever mechanism you want to use ) and set the Size property on the button accordingly.

Here's one rather simple and sloppy method for resizing a single button:
using System;
using System.ComponentModel;
using System.Windows.Forms;
namespace CP_CSharp_SizeButton
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left && this.Cursor!=Cursors.Default)
{
if (this.Cursor==Cursors.SizeWE)
button1.Width = e.X;
else
button1.Height = e.Y;
}
else
{
if (e.X > button1.Width-5 && e.X < button1.Width+5)
this.Cursor=Cursors.SizeWE;
else if (e.Y > button1.Height-5 && e.Y < button1.Height+5)
this.Cursor=Cursors.SizeNS;
else
this.Cursor = Cursors.Default;
}
}
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
this.Cursor = Cursors.Default;
}
}
}

Thank you, I get your solution
Hello
|
|

hello every one, well I'm making a form in a windows aplication in C#.net 2.0. What I'm trying to do is to present the user with one option on each tab but I want them to go in a sequence. So all I wanna do is that the user should select the value form the first form then press a button to go to the next tab and so on untill he reaches the last tab u knwo. So how can I restrict the user from accessing a tab and to navigate to the next by presin a button or something u know.
thanks in advance.

You can cancel the navigation by handling the TabControl's Selecting event. But imho, you should use a wizard metaphor instead. A tab control is generally intended to allow the user to access any tab at any time. Detracting from this paradigm could cause user confusion.

i m calling a web method through ma client which returns a xmlnodelist but it is not working and returns the following error
To be XML serializable, types which inherit from IEnumerable must have an implementation of Add(System.Object) at all levels of their inheritance hierarchy. System.Xml.XmlNodeList does not implement Add(System.Object).
i cant understand where does this error leads to???
Warm Regards
Bia

First,
In what point this exception has been thrown?
Second,
from what is looks like in the error itself and in the information from the metadata and http://msdn2.microsoft.com/en-us/library/system.xml.xmlnodelist_members.aspx[^] it looks like XmlNodeList (or the classes it inherit from) doesn't implement the proper interfaces so it could be serialized... and you can't transfer it from your web service to the client...
so it looks like this error leads to finding another way transfering the data 
good luck,
Tal Kain.

Is there any way to do something like this:
StartScreen.mCP.talkTime("#FM", "01", {newINIs, items});
Which is to say passing in an array without actually making the array, or do I need to do it like this:
object[] o = new object[] {newINIs, items};
StartScreen.mCP.talkTime("#FM", "01", o);
Something like the first way would be better more useful, but Visual Studio doesn't like it, so...

Hi.
Try something like this
<br />
StartScreen.mCP.talkTime("#FM", "01", new object[]{newINIs, items});<br />
I don't know if it'll work, but try it. One never know.

You are still creating the array, though...
---
b { font-weight: normal; }
|
|
|
|
|
Yeah, but I'm now creating a temporary array inside the method call, which is how I wanted it.
Plus if I call half a dozen methods, I dont have to remember what names I've used for the arrays previously. (The contents of the array assumed to be different for every call because it's something the user can modify whenever he wants to)

Just wanted to be clear on whether it was the actual creating of an array that was the problem or not. 
---
b { font-weight: normal; }

The easiest way to do it is to create a new collections class. The collection class can be of whatever you need. Now your parameter is the class object. You populate it with what you need in the parent method, pass in the populated class to the called method.
|
|
|
|
|
Nah, because I'd still need to adjust the collections class before I used the method, because the contents of the array changes every time the method is used.
The array can be null; a string; a string and a boolean; an array, 2 booleans and a string; etc, and it's contents will be different every time it's called.
All in all, much easier to use the (new Object{}) code to pass stuff into the method.

Good day.
I'm writing my first program for a company. The program will interact with Microsoft Word & Excell. It will do basic stuff such as Mail merges and inserting text at bookmarks.
A basic accounting system will be needed. Nothing fancy.
A register with customer information and contact details aswell as employee information will also be needed.
Now:
Which method should I use to store the data? Obviously I can use Access to do the database handling, but would it be recommended? If not, why not? and which other methods can I use to do my data handling?
If you recommend I use Access, will it be secure and are there any methods I can use to try keep someone from finding out the database structure and messing with the data inside the file itself?
I know it's alot of questions, but your help will be greatly appreciated.
Thanks alot

Depends on the data. By the sound of it you need a database.
LiquidE_SA wrote: Obviously I can use Access to do the database handling, but would it be recommended?
Probably not.
LiquidE_SA wrote: If not, why not?
Because it is not an enterprise database system and it doesn't scale. The purpose of a company is to make a profit. To continue making profits the company will grow. In order to grow it needs systems that will grow with it.
LiquidE_SA wrote: and which other methods can I use to do my data handling?
SQL Server.
LiquidE_SA wrote: Access, will it be secure and are there any methods I can use to try keep someone from finding out the database structure and messing with the data inside the file itself?
It isn't as secure as SQL Server that much is certain.
I have a question for you:
How big is the company? Regardless of size I'd recommend SQL Server unless they have a exceptionally compelling reason to use Access. So, why would you want to use Access?

Sorry. I think I didn't explain properly. The product I'm developing is a product that will be sold to alot of different people. It will aid them in doing some basic stuff. Therefore I need a method/way of handling the database, wihtout installing extra servers/software.
The thing as I understand it with SQL Server I'll need to install it on every machine that will run the application. That will cost alot of money, won't it?
Isn't there methods of doing datafile handling and data integrity chechs from within C#?
I need something that I can bundle with the application.
Thanks alot

How much data?
LiquidE_SA wrote: The thing as I understand it with SQL Server I'll need to install it on every machine
Well, no. As the name suggests it is a "server" product. So, it is installed once on a server (in large organisations they may have many SQL Servers to spread the load)
LiquidE_SA wrote: That will cost alot of money, won't it?
SQL Server 2005 Express Edition is free - but it has some restrictions (but not as limited as Access)
LiquidE_SA wrote: I need something that I can bundle with the application.
SQLLite or VistaDB may be choices - but you still need to answer the question "How much data?"
Some companies make products that are specifically designed to sit on top of SQL Server. Perhaps you can do that. If you are marketing to small businesses they may already have Microsoft Small Business Server which has SQL Server built in. When that company grows they can migrate to a full SQL Server easily.
So far, I don't think you've provided enough information to say which database is a good choice. How does the application interact between users? Is it even multiuser?
LiquidE_SA wrote: Isn't there methods of doing datafile handling and data integrity chechs from within C#?
You can do that in C# if you want - but do you really want to be reinventing the wheel?
