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.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

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.

There are a number of errors in your post (please read the guidelines).
Your title is not acceptable - it is not urgent to anyone but yourself
Your posted code is not inside pre tag and is difficult to read.
You have not indicated where you get the error (what line)
You did describe the error so I can tell you there is an object that is declared but not initialised. Try debugging through the code to identify the line, look for an object that is 'null' where you expect it to have a value.

You can't. How do you expect to get progress notification from Word ?
If you're taking steps in your own code, you show a progress bar, as explained in a ton of articles.

Sure there is, there are many articles here on progress bars. However what CG was referring to is how are you going to define the progress of the open function. This is why there is a little circular animation used, you have no idea how long it will take.
