I've created a customized control that is basically a textbox with some labels. Among other things, I'm trying to expose a couple attributes of the textbox (called myText).
Within the class of the user control, I've put
<br />
public bool Multiline<br />
{<br />
get { return myText.Multiline; }<br />
set { myText.Multiline = value; }<br />
}<br />
This is all fine, and I can modify this within code, but how do I get this property to show up in the properties window in the .NET designer? Is there some special tag I need to put before it?

That's all you need, if you want to set the description (displayed at the bottom of the property grid) then use the [Description("Your description")] tag, likewise there's a category attribute (when the property grid is in the category view) and a few others such as designer (not applicable to this property).
But basically any property is by default displayed in the property grid. To hide it use the [Browsable(false|true)] attribute.

Turns out all I needed to do was re-open the designer where I was trying to use the custom form. That got it showing up. Anyways, thanks for the help, and the advice on [Description()]

hi Drew McGhie! 
basically, your code is already fine...
maybe the "myText" textbox is not initialized? if the initialization of this textbox was done on the InitializeComponent method... there would be no problem. perhaps you do the initialization by demand?
hope this helps!

I also have the same proble but this code will help you some what....
Pop3Message msg2 = obj.Retrieve(msg);
Response.Write("Message {0}: {1}");
Response.Write(msg2.number);
Response.Write("aashu1");
//int i = msg2.message.IndexOf("Content-Disposition: inline");
//int j = msg2.message.Substring(i).IndexOf("------=");
//int k = msg2.message.Substring(i).Length;
//int p = k - j-1;
string str1 = Regex.Match(msg2.message, "\nTo <to>[^\n]+)\n", RegexOptions.IgnoreCase).Value.ToString();
string str2 = Regex.Match(msg2.message, "\nFrom <from>[^\n]+)\n", RegexOptions.IgnoreCase).Value.ToString();
string str3 = Regex.Match(msg2.message, "\nCC <cc>[^\n]+)\n", RegexOptions.IgnoreCase).Value.ToString();
string str4 = Regex.Match(msg2.message, "\nSubject <subject>[^\n]+)\n", RegexOptions.IgnoreCase).Value.ToString();
int h = msg2.message.IndexOf("\n\n");
string str5 = msg2.message.Substring(h+4);
Response.Write(str1);
Response.Write("

[VS .NET 2005] i want to add by code an image into resource library starting by the path of the image... how?
|
|
|
|

You cannot add an image into the resources (.resx) of an application without recompiling the whole thing, AFAIK. This is because embedded resources are actually compiled into the target app.
Perhaps if you describe what you're trying to accomplish, we might be able to help you find an alternative solution.

i do that to load an image and set as background for a panel, but it works on my pc where i have got the images then if i run it on another pc it doesn't show background image couse they aren't on the other pc, so i've think to move it into resource:
[EditorAttribute(typeof(MyFileNameEditor), typeof(UITypeEditor))]
[Category("Image state"), Description("Mouse over image")]
//[DefaultValue("")]
public string MouseMovePath
{
get
{
return MouseMove_path;
}
set
{
try
{
MouseMove_path = value;
FileStream fs = new FileStream(MouseMove_path, FileMode.Open, FileAccess.Read);
move = Image.FromStream(fs);
fs.Close();
this.Invalidate();
}
catch
{
MouseMove_path = "(none)";
}
}
}

Use Resourcer. You can add image to resource file.

Concerning: C#, OdbcDataReader, MySQL, MyODBC
I've built a service which every x seconds performs a series of checks and if they all validate true, it launched a conversion which takes up to 20 minutes.
While converting the service still performs these checks every x seconds and that's all good  )
So now I've got like a two-threaded monster; one performing checks while the other is performing a conversion.
ENTER THE PROBLEM:
I'm using MySQL as the database. I use MyODBC to establish the connection and the OdbcDataReader to read my recordsets. OK! The database connection can only have ONE active OdbcDataReader at a time and now my two-threaded monster gets conflicted.
Queries from the checks can't access the database while the conversion has an active OdbcDataReader and even worse the conversion sometimes fails because of the checks |
I've built a simple MySQL class with the methods:
open(...)
query(...)
close(...)
Which I pass round to all the objects (I tried creating new instances each time and I got the MAX Connections Exception'ish Error).
Is there anyone out there who can help my out of this hole I've seem to have dug myself into?
It isn't supposed to be easy, if you know what I mean

You have two problems:
1. You are trying to share a database connection between threads.
2. There is some database object that you are not closing properly.
Don't try to share the connection. Give each thread a connection on it's own. Actually, don't even hold on to the connection when you don't use it.
Remember to close database connections and datareaders when you are done with them. If you don't, the connection will remain open, and you'll run out of available connections.

Hi I am making a program in Visual studio 2005, but I have run in to a problem. The compiler will not accept the following line of code:
string[] strsplit = strFileName.Split(new Char[] {'\'});
The compiler will however accept this line of code:
string[] strsplit = strFileName.Split(new Char[] {'2'});
So the problem must be the “\” character. Is there anyone who knows how to make the compiler accept this specific character?

\ is an escape character used to create unprintable characters such as the carriage return '\r' and line feed '\n'.
In order to add a \ to a string or char, you must escape that escape character like this '\\'.

Use @"\"
e.g.
"C:\Program Files\Microsoft" <- wrong
@"C:\Program Files\Microsoft" <- OK

Hello,
How to save my DataTable, to my HD ?
If I written something like that :
// Create a DataTable.
DataTable table = new DataTable("Product");
// Create a DataColumn and set various properties.
DataColumn column = new DataColumn();
column.DataType = System.Type.GetType("System.Decimal");
column.AllowDBNull = false;
column.Caption = "Price";
column.ColumnName = "Price";
column.DefaultValue = 25;
// Add the column to the table.
table.Columns.Add(column);
// Add 10 rows and set values.
DataRow row;
for (int i = 0; i < 10; i++)
{
row = table.NewRow();
row["Price"] = i + 1;
// Be sure to add the new row to the
// DataRowCollection.
table.Rows.Add(row);
}
And now I want to save my DataTable, to my HD in the current directory with a name like "MyDataTable.mdb" ?
How I code it ?
Thanks.

Try this to save to XML on HDD:
//Instantiate DataSet
DataSet ds = new DataSet();
//Add the table to the DataSet
ds.Tables.Add(table);
//Write XML output to HDD where filename is full path
ds.WriteXml(filename);
I hope this helps give you a few hints.

hello,
i'm working on a .NET windows form. i have programmatically created a column of buttons using the following code:
for (int j = 0; j < farmData.Tables["plate"].Rows.Count; j++)
{
Button viewBtn = new Button();
viewBtn.Text = "View";
viewBtn.Name = "viewBtn" + j.ToString();
viewBtn.UseVisualStyleBackColor = true;
viewBtn.Click += new System.EventHandler(this.viewBtn_Click);
tbl.Controls.Add(viewBtn, 0, j + 2);
}
when i push a button, and the viewBtn_Click method is called, how do i get the button name so that i know exactly which button was pushed?
Thanks in adavance for any insight!

You should be able to cast the sender parameter to Button type: Button button = (Button)sender;

that did the trick.
thank you!

could you direct me to any sites that explain how to use custom buttons on titlebar Close/Minimise etc
|
|
|
|
|
please read the top thread in here ("How to get your answers...")
posting the message twich is not very much smart like this.
the least you can do is search the codeproject for articles like this, but this is so small... just make a button, and register to the click event, and on the method you can do either
this.Minimise();<br />
this.Close();<br />
Application.Exit();
etc...
|
|
|
|

The title bar is a non-client area. You can't "just make a button" and drag it there as you would in the middle of a form. If it were that easy, the question likely would not have been posed.
Also, your making snide comments about how smart others' questions are is not recommended--at least not while this forum's contents can be searched through by name.
