Hi All
Look at the code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace DealingWithImages
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.label1 = new System.Windows.Forms.Label();
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(53, 52);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(211, 13);
this.label1.TabIndex = 2;
this.label1.Text = "This is windows forms do you like it?";
this.Controls.Add(label1);
Image myimage = Image.FromFile(@"Give path of the image");
this.BackgroundImage = myimage;
this.MaximumSize = new System.Drawing.Size(400, 400);
this.MinimumSize = new System.Drawing.Size(400, 400);
}
protected override void OnMove(EventArgs e)
{
base.OnMove(e);
this.Refresh();
this.Invalidate();
}
protected override void OnPaintBackground(PaintEventArgs e)
{
if (this.BackgroundImage != null)
{
e.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;
e.Graphics.DrawImage(this.BackgroundImage, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height);
}
else
{
base.OnPaintBackground(e);
}
}
}
}
I have to put image on the background of my windows form which I am doing using the code above.
I have some controls which I am generating at runtime.
Now the challenge is the background color of the control(here label1) looks odd on the form.
Does anybody know How to solve it?
Thanks
Regards
THE SK

Hi,
I am building a ASP.NET page using c#.
I need a code to add a javascript function to disable a button on a text change event.
The below is the code i wrote
The script code in tags:
function SetButtonStatus()
{
document.getElementById("Button2").disabled = true;
}
other codes here
this is the textbox tag:
<asp:textbox id="txtName" runat="server" onchange="SetButtonStatus()" xmlns:asp="#unknown">
It doesn't seem to work. Please help me on this one. I tried this in ASP.Net forums there were no replies

I would suggest just doing it in your code behind. This is a bit of c# code that works.
On the aspx page :
<asp:textbox id="TextBox1" ontextchanged="TextBox1_TextChanged" autopostback="true" runat="server" xmlns:asp="#unknown">
<asp:button id="Button1" runat="server" text="Button" xmlns:asp="#unknown">
in the code behind
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
Button1.Enabled = false;
}
Now take note to the field AutoPostBack="true" this will update the button automatically after you click out of the textbox itself, which will cause the page to update. If you want to manually update the page you can just remove that line.
Hope that helps

Before doing your insert you should check first to see if the table exists, at which point you can specify another name for the table. I would dynamically set the table name in your code as a variable, and do a count on how many tables with that name already exist, and then create a new table based on that name and the count. This link may help you with the code on checking first to see if the table exists.

hope this helps.

Something about this question just seems wrong to me. There should be one table in your database that contains all your "Customers" for example. Seems like a bad design to have "Customer_1_Jan_2009", and "Customers_2_Jan_2009", will you really want to query 'x' Customer tables for given date range as in the example provided?
Alternatively, if you have for example a Customer table in your database, and each customer might need some additional data for each individual customer, i would highly suggest storeing the additional information within an xml column if possible.
Or better yet figure out exactly what data you need to store, track, and maintain. You might have some specialized need to store data in this manor, but i simply can't think if a reason for it, seems like a bad design, and if you need to store daily inform for a given customer, then the date value should simply become a value withing the record.

You must be more precise about what 'controle' means to you. Do you mean limit them in some way, or do you mean keep track of them, or what?
How can anyone help you with such an imprecise question?

Hi.
I'm going to write a program for coloring and formatting C# Codes.
But I have an issue ?
When a word inserted by user, how I can find whether it's a class name ( in C# )
For example :
If a user has written Regex in the code editor, I wanna detect it as a class and dye it with a appropriate color.
Now , how can I realize whether a string is a class name in C# ?
Thanks in advance.

There's an article on CP somewhere that does something like intellisense in a rich text box. I can't find it right now but it shouldn;t be too hard to modify that code for what you want - if you can find the article.
[Edit] Found it here[^] [/Edit]

Thanks, but it's a little complex project, and it takes me long time to find what I want.

10 minutes since I posted the link isn't 'long' 
The theory is the same - keep a list of all loaded assemblies namespaces, properties, methods, fields, events, interfaces etc... and check against that list to set the color.

Can I take all classes name in C# with Reflection ?
Sorry, if my question is wrong

Not sure in all honesty. If you can, you'll only be able to get at loaded/referenced assemblies unless you search through the dll's in the .net framework recursively - could be a long task that way.

Hi,
IMO you should collect the namespaces present in the referenced DLL files; and for each #using statement, investigate the namespace, collect all relevant names, and keep them in a fast collection, such as a HashSet or a Dictionary.
