Hello,
I'm creating a setup project for my application. I need to ask user to specify a directory during installation, which I have to set a registry key value to that directory. I've done this for installation directory but I don't know how to ask user to specify another directory as well and how to set the registery accordingly.
Any idea would be appreciated.
Thanks & Regards
P.S. I'm using wisual C# .NET

Hi,
You can add one form in user interface where user can select the path of the folder and that path will be referenced in the coding for writting the registery.

Hey all,
I'm sure this is a no-brainer for most of you, but it's something I never learned about in the old procedural days, so any help appreciated.
I keep reading about the Singleton, and looking at the implementations, folks talk about thread safety etc. etc., such as in this article: http://www.yoda.arachsys.com/csharp/singleton.html.
However, I was under the impression that if a class was declared as public static it would have application scope, but couldn't be instantiated, and so would only exist once within an application... so any methods or properties you put in a static class will also only have one instance.
I must be missing the point here somewhere - one conclusion I've come to is that you infact wrap another object, that would normally be instantiable, within a singleton class, in effect making the wrapped object a Singleton as well... is this the case?

Its important to get one distiction solid in your mind.
A singleton is a single instance of a clas.
So, you should write whatever class will be a singleton in the normal manner before starting. ie/
public class MySingleton
{
private string someVar = "";
private MySingleton()
{
}
public string SomeVar
{
get{ return this.someVar; }
set{ this.someVar = value; }
}
}
Note this has instance variables/accessors. The other thing to note is that it has a private constructor only!! This stops new instances of being created for this object (except for within the code).
Now, the purpose of a singleton. If, for whatever reason makes sense for your application, there should only EVER be one instance of MySingleton it is a candidate for the Singleton pattern.
1 line change
public class MySingleton
{
public static readonly MySingleton Current = new MySingleton();
private string someVar = "";
private MySingleton()
{
}
public string SomeVar
{
get{ return this.someVar; }
set{ this.someVar = value; }
}
}
Now, in your app you could have:
MySingleton.Current.MyVar = "Hellow World";
For examples of Singleton use within the framework look at HttpContext.Current in the System.Web namespace.

hi all,
first: i have a tabcontrol page and it contains a few textbox and 3 buttons (insert, cansel, close).
i tried to arrange taborder for this page but interestingly Insert button has a precedence according to textboxes although i selected textboxes to have taborder first ;(
its weird. is there something wrong with my form ? or do i miss something ?
my taborder (did in this order) : pagetabs > textboxes > buttons (insert, cansel, close)
but form's tab order : pagetabs > insert button > textboxes > the other 2 buttons.
second: for cansel button i just initialize textbox(n).Text=""; what should i do to make comboboxes to show nothing ? combobox(n).Text=""; doesnt work  i dont want to add or remove something from comboboxes. just want not to show any item inside.
third: i use tooltip to give some info about for pagetabs. but if i open another tab then move back to the previously opened tab. tooltip doesnt show anythin any more ;(
how do i edit tooltip properties so as to enable it to show infos continuously even i browse in tabpages ?
thanks in advance.
bye.

1. The tab order will work fine, but you should try taking the control that you want the user to be on first and calling Focus() on it. You can listen for the event when the user switches tabs and do it there, or when the tab pane becomes visible.
2. You can use the Text property with a combobox. What is your DropDownStyle set to? If the combobox requires that a list item be picked, then it's not going to let you clear out your text.
3. Are you using the SetToolTip method? Is the container your form or the tab pane? Have you tried listening for the tab switch event and resetting your tooltips?

If that text appears more than one time it should select all that occurances.
Is it possible to do that?
Wat im using curently is as follows..
int startindex = 0;
int tmp = rtxbox.Text.ToUpper().IndexOf(txtFind.Text.ToUpper());
if (tmp > -1 && rtxbox.Text.Length > 0)
{
startindex = tmp;
rtxbox.Find(txtFind.Text);
rtxbox.rtxbox.ScrollToCaret();

You can convert it to ASCII :
Encoding srcEncoding = Encoding.Unicode;
Encoding tgtEncoding = Encoding.ASCII;
byte[] byteInUnicode = Encoding.Unicode.GetBytes("your string");
byte[] byteInAscii = System.Text.Encoding.Convert(srcEncoding, tgtEncoding, byteInUnicode);
string strInAscii = Encoding.ASCII.GetBytes(byteInAscii);

What do you mean by "not getting executed"? Is there an error? What is the exception message? Is it doing nothing at all?

Hi,
I'm having a situation like this.
I am using a datagridview which fills up Item details from a table, say Items.
I am also adding a Datagridcomboboxcolumn to this datagrid whose datasource is table 'Category' from where it should show various category names in combo box for user to select one.
I can see the datagridview being filled up with data from Items table.I can also see the combo box column being generated for each row.However, the combobox doesnot work and show any values from its datasource.
How can I show rows from one table and combo box in each row from other table in a datagridviw ?
here is the pseudocode :
DataTable dt = objItems.GetItems(); // gives Item details in a table.
DataTable dtCat = objCat.GetCategory(); // returns category details in form of a table.
dgItems.DataSource = dt; // dgItems is a datagridview created with the help of toolbox on a winform.
DataGridViewComboBoxColumn comboColumn = new DataGridViewComboBoxColumn();
comboColumn.DataPropertyName = "CategoryDesc";
comboColumn.HeaderText = "Select Category";
comboColumn.MaxDropDownItems = 5;
comboColumn.DataSource = dtCat;
comboColumn.ValueMember = "CategoryId";
comboColumn.DisplayMember = "CategoryDesc";
dgItems.Columns.Insert(dt.Coulmns.Count + 1, comboColumn);
Thanks in advance.

Hi to all,

I have an applications in which I add controls to a treeview (treeview = container). The problem is that when i scroll my treeview, the nodes move but the controls stay at their place ( the don't move in other words). ANy idea on how to make them move and keep their raltive position (now they are located next to the node which handles as the controls label)
kind regards,
