I am creating a mp3 player through C#.Net I have kept a CheckBox that shows the play list. I have created the player such that it when ever the user cicks on the selection on checkbox the player play the corresponding song. so the user has to click on the next song to play the next song once the previous song is finished.
Now I would like to know is it possible for the player to automatically play the next song once the previous song is finished? If so how do I go about doing this on C#.Net
Please let me know... Thanks!

Hi All,
I have a TextBox txtBx, I set text to it as-
txtBx.Text = "brutas\n\nhong\t\nsaw";
now on the application, raw characters(square boxes) are shown in stead of \n, \r etc.
I want the display in the textbox as
brutas hong saw
can any one help me?

You could use a Regex:
string s = "brutas\n\nhong\t\nsaw";
Regex r = new Regex("[\n\r\t]");
string t = r.Replace(s, " ");

I am using a program to insert values in a table in an SQLEXPRESS database. My program tells me that the queries are being executed but when I check on the Database Explorer in Microsoft Visual Studio 2005, I do not see the values.

Run the SQL Profiler and see what query is actually getting run on the database. This might help you find the problem.

I created Windows Service in C#.net
In this Windows Service I successfully connect to local sql server 2000 install in My PC.Then I retrive data from local sql server 2000 and fill that data into one dataset.Now I Want to connect to remote sql server 2000 to insert that data into database of that sql server 2000.

|

Seems like changing the connectionstring is enough to change database. Have you changed your connectionstring to connect another database. Is it possible for you ti share the code.
|
|
|
|
|
You can keep the connection strings in app.config file under the onnectionstrings section and read it using ConfigurationManager.ConnectionStrings

Hi.
I've created a service and installed it with following code :
public static void InstallService(string ExeFilename)
{
System.Configuration.Install.AssemblyInstaller Installer = new System.Configuration.Install.AssemblyInstaller(ExeFilename, new string[] { });
Installer.UseNewContext = true;
Installer.Install(null);
Installer.Commit(null);
}
I wanna start it after install, could you please guide me how I can do it ?
Thanks.

I am creating a custom control derived from ComboBox. I add some items to custom control in constructor of control.
// this code is sample
public MyCustomControl
{
this.Items.Add("test1");
this.Items.Add("test2");
}
When I drag this custom control to my form, designer auto-generate the code:
// this code in Form1.Designer.cs
this.mycustomControls.Items.AddRange(new object[] {
"test1",
"test2"});
When this custom control display on Form1, will have 4 items:
test1
test2
test1
test2
This problem cause duplication.
Please help me how to solve this problem, I don't want designer auto-generate these codes. Thanks.

The Question is how do you Display a Form ?
Form1 frm1 = new Form1();
frm1.Show();
i have not been doing win apps for a while now , but that is how its done.
My point is that need to create that form first and show it later.

Windows services don't interact with the user using UI.In fact they are "background" processes and it's not not safe to control the UI outside of the default drawing pool.If you need to control the service programatically
define your own custom commands and send them to the service using ServiceController.ExecuteCommand method.See this sample.And if you need to report for some errors use the event log.
Life is a stage and we are all actors!

In service properties at Log On tab "Allow Service to interact with desktop" should be checked.

Hello Friends
I have a TreeView which has many nodes which are are being created dynamically.
I have set a check box against each node of that TreeView. Now My Problem is I need to work with it's Click event. But how can I hold it.?
Here's The code where I do this.
private void BuildTree(List<ParentChild> liParentChild)
{
List<ParentChild> liParent = liParentChild.FindAll(delegate(ParentChild oParentChild) { return oParentChild.ParentID == 0; });
foreach (ParentChild currentParent in liParent)
{
TreeViewItem currentParentNode = new TreeViewItem();
currentParentNode.Tag = currentParent.ID;
string folderImagePath=@"C:\Documents and Settings\Sharif\My Documents\Visual Studio 2008\Projects\TreeView\TreeView\Images\FolderOne.jpg";
// string lowerLevelImagePath=@"C:\Documents and Settings\Sharif\My Documents\Visual Studio 2008\Projects\TreeView\TreeView\Images\FoldeTow.jpg";
string fileImagePath = @"C:\Documents and Settings\Sharif\My Documents\Visual Studio 2008\Projects\TreeView\TreeView\Images\File.jpg";
#region image and font style
StackPanel oStackPanel = new StackPanel();
oStackPanel.Orientation = Orientation.Horizontal;
CheckBox oCheckBox = new CheckBox();
oCheckBox.Name = "cb_" + currentParent.ID;
//oCheckBox.IsEnabled = false;
oStackPanel.Children.Add(oCheckBox);
oStackPanel.Children.Add(CreateIcon(folderImagePath));
TextBlock tb = new TextBlock();
tb.Text = currentParent.Name;
oStackPanel.Children.Add(tb);
currentParentNode.Header = oStackPanel;
#endregion
AddTreeChild(currentParentNode, liParentChild, currentParent,1,folderImagePath,fileImagePath);
tvParentChild.Items.Add(currentParentNode);
//ExpandAll(tvParentChild);
//CollapseAll(tvParentChild);
}
}
private void AddTreeChild(TreeViewItem currentParentNode,List<ParentChild> liPC,ParentChild currParent,int level,string folderImagePath,string fileImagePath)
{
int currntLevel = level + 1;
List<ParentChild> liChild = liPC.FindAll(delegate(ParentChild oParentChild) { return oParentChild.ParentID == currParent.ID; });
foreach (ParentChild currentChild in liChild)
{
TreeViewItem currentChildNode = new TreeViewItem();
StackPanel oStackPanel = new StackPanel();
oStackPanel.Orientation = Orientation.Horizontal;
currentChildNode.Tag = currentChild.ID;
#region font style and image
string sourcePath;
if(IsLeaf(currentChild.ID,liPC))
sourcePath = fileImagePath;
else
sourcePath = folderImagePath;
if (currntLevel % 2 == 0)
{
//currentChildNode.FontStyle = System.Windows.FontStyles.Italic;
currentChildNode.Foreground = Brushes.Brown;
//currentChildNode.Background = Brushes.White;
}
else
{
//currentChildNode.FontStyle = System.Windows.FontStyles.Normal;
currentChildNode.Foreground = Brushes.Black;
//currentChildNode.Background = Brushes.White;
}
CheckBox oCheckBox = new CheckBox();
oCheckBox.Name = "cb_" + currentChild.ID;
// oCheckBox.IsEnabled = false;
oStackPanel.Children.Add(oCheckBox);
oStackPanel.Children.Add(CreateIcon(sourcePath));
TextBlock tb = new TextBlock();
tb.Text = currentChild.Name;
oStackPanel.Children.Add(tb);
currentChildNode.Header = oStackPanel;
#endregion
AddTreeChild(currentChildNode, liPC, currentChild,currntLevel,folderImagePath,fileImagePath);
currentParentNode.Items.Add(currentChildNode);
}
}

1. Use pre tags when posting code. It looks more readable.
2. If you set the CheckBoxes property of the treeview to true, it will show checkboxes before each node. Then you can handle the NodeMouseClick event and capture the click.
3. If you still go will the current apprach, handle the CheckChanged event for each checkbox you add.

Hello All,
Is there anyway in which i can create a word document programmatically without using Office Interop or third-party libraries.
|
|
|
|
|
Yes - you can rewrite word, or if you want to only support the new version of Word, you can learn it's XML format and write something that uses that.
