But not urgent enough to use google ?
If the book you're using doesn't cover timers, it probably lacks in other areas. Buy a better book, and keep applying yourself.
Or try here[^].

I currently have an application in which i am storing a connection string in a class. I would like to not have to hardcode this into the class, but instead store it in some sort of text file.
I thought of placing this into a text file, but I want to be able to hide this file, and not allow user to view the connection string.
Thanks for your help.

Put it in your settings, and encrypt it so the user can't change it.

What i have done is placing the connection string setting in the text file .
[code]
StreamReader sr = new StreamReader(@"C:\ConnectionString.txt");
ConnectionString = sr.ReadLine();
[/code]

Sure - but that doesn't solve your problem, does it ? It can, if you also encrypt the string, but why create an extra file when .NET has this sort of stuff built in to it via the app.config file ?

Good People,
I need some advice on what direction I should take. I have been asked to write an application. While I know C# and the nuts and bolts of coding and software design (to a reasonable degree), I don't know how to make it look nice. They want it to have a nice looking GUI, cool buttons, pictures and other graphics to augment the software experience. Yep, this application is also meant to be fun and interesting to use, thus they don't want it to feel like they're using MS Access or some other mundane application.
At any rate, I do have some time so I'd like some advice on what I need to learn to do that type of stuff. For example, how do I make semi transparent menus and glossy buttons? How do I add images on a page that will scale properly? Is WPF the answer.
Any advice you can give me on what directions I need to take will be helpful. Also, if you know of any articles I should read on this site let me know.
Thanks,
BP

From what you've described, I'd go with WPF.

Thanks, I appreciate it.
Is there a good place to start?

I use WinForms DataGridView in Virtual mode based on MSDN samples.
Grid data is cached in paged List<TEntity>
Data is retrieved in OnCellValueNeeded() event
using DLinq Skip()/Take() methods from server database.
I have implemented column search feature which allows to locate row whose
column contain sertain value.
I use DataGridView method for it:
void LocateInColumn() {<br />
<br />
SearchFor = Microsoft.VisualBasic.Interaction.InputBox(<br />
Columns[CurrentCell.ColumnIndex].HeaderText,<br />
"Locate value",<br />
"", -1, -1);<br />
<br />
int col = CurrentCell.ColumnIndex;<br />
for (int i = CurrentRow.Index + 1; i < RowCount - 1; i++) {<br />
object val = this[col, i].Value;<br />
if (val == null) continue;<br />
if (val.ToString().ToUpper().<br />
Contains(SearchFor.ToUpper())) {<br />
CurrentCell = this[col, i];<br />
return;<br />
}<br />
}<br />
MessageBox.Show("Not found");<br />
}
This code causes all data to be readed over internet connection and is very slow.
I cannot use Where clause directly since I need to show also rows before and next located row.
How to locate row without reading whole database ?
I can use where clause to find row id. However I have no idea how to position virutal grid to this row
so that rows before and after are also visible.
Is it possible to implement in easily in some other GUI: GTK#, Silverlight, WPF ?
Are there any grid control available which implements this ?

I have DataGridView in WinForms form.
DataGridview contains custom ComboBox columns and standard TextBox columns. Edit mode is EditOnEnter.
Form contains also some Text Boxes.
When focus is moved out of DataGridView, its current cell is displayed as selected state (blue background).
How to remove this highlight so that selected cell is not highlighted at all (or highlighted only when grid is active control)?

Hello Andrus,
You can try the following code in the LostFocus() event of DataGridView.
Me.DataGridView1.CurrentCell.Selected = False
I hope this helps.

Allen,
thank you.
It works.
When my form is loaded, grid does not have focus. In this case grid first cell is highlighted.
I tried to set Selected false in Grid constructor
public Grid() {<br />
InitializeComponent();<br />
CurrentCell.Selected = false;<br />
}
But got NullReferenceException since CurrentCell is null
How to disable cell selection when grid is initiated ?

The split method of the string class will do this for you.

A string is an array of chars. foreach(char c in "12345") will iterate over the numbers. If you have non numbers in your string, Char.IsDigit will tell you if it's a number.

I have no idea where your code is broken, you've not posted it.
foreach(char c in "12345")
{
switch(c)
{
case '1':
// print 'one'
// etc
}
}
will most certainly work.

Ah, but a Dictionary<char,string> would be so much more flexible and the teacher will be most impressed.

|
|
|

Yeah, until the teacher asked him to explain the code....

Oh, in that case maybe an enum.
