Can Any one Help me Abt Dynamic(Runtime) Dll, how to implement it in C#.Net. When ever i am compiling my project all the dll should not be compiled. It means that a particular dll has to be loaded when ever i had called, else it should not.

Sorry I'm not completely understanding, do you want to compile the dll conditionally, only when you want, or do you mean that the application should only load the DLL when it is needed (which is the decault behavior in .NET anyway) ?

My requirement is to have multiple .Net dlls, which has similar functionalities exposed (so that I can expose functions of same signature). One of these dlls should be loaded at runtime based on user's selection of dll file name. In effect I need to support my application in such a way that, even after initial deployment, I will be able to deploy additional dlls (additional dlls alone will be separately deployed), which user can select at runtime.

Subscribe to the Popup event of the context menu. There, you can selectively enable/disable menu items based on the currently selected TreeNode.

I have a MDI application where there is a login mdi child form from which the main form(another mdi child) opens up if the login is successful. The main form has some functions which take time, in the meanwhile when the main form is opening if the user switches over to another window from the taskbar(i.e., my application loses focus), the main form opens in a separate window outside the MDI parent form and prevents the user from navigating to any window in the taskbar and the main remains on top of all other windows in the taskbar. If the application is in focus then it opens inside the MDI parent form.
Thanks

Why is your login form an MDI Child? I haven't seen a single application where this is done, nor appropriate. A login form has always been a modal dialog box, preventing further access to the application until the required credentials are filled in.
If your main form opens in a seperate window, outside the MDI Parent, it sounds like your main child form didn't have its Parent property properly set to your MDI Parent form.

Thanks for reply, the menu options of the application are disabled till the user successfully logs in, so the user doesnt have access to any feature of the application. The main form opens properly if the application doesnt lose focus i.e., if the user doesnt switch to any other window from the taskbar. Here is the code from the login page:
private void button1_Click(object sender, System.EventArgs e)
{
//rest of the code omitted
this.Close();
frmDoNext objfrmDoNext = new frmDoNext();
objfrmDoNext.MdiParent = frmMainForm.ActiveForm;
objfrmDoNext.Show();
}
frmDoNext is the main child form and frmMainForm is the parent form.
Thanks

One potential problem I see is that you're using .ActiveForm to set the parent of the child form. Don't. Use a known reference, that you're sure is the correct form, to set the parent. Since child forms can't have child forms of their own, there's no reason to use .ActiveForm to set the parent of a child.
frmDoNext objfrmDoNext = new frmDoNext();
objfrmDoNext.MdiParent = this;
objfrmDoNext.MdiParent = this.MdiParent;
objfrmDoNext.Show();

Hi all,
Ineed your help translating this bit of code having no idea how to translate the "Handles" statement.
Any help will be appreciated
---------
Private Sub Application_SelectionChanged(ByVal Window As Office.Interop.Visio.Window) Handles visioApplication.SelectionChanged
Dim mywindow As Office.Interop.Visio.Window = Window
NumOfShapes = mywindow.Selection.Count()
MyShape = mywindow.Selection(1)
ReadANamedCustomProperty(MyShape, "HoursPerWeek", )
End Sub
|
|
|
|
|
I *think* (from very limited VB experience) the Handles statement implies that the Application_SelectionChanged method will get called when the visioApplication.SelectionChanged event is fired.

My thoughts exactly but how can I hook this event from my application (COM Add-in) in the same way that the "Handles" statement does it?
thanx anyhow
|
|
|
|
|
Having no experience whatsoever with a COM add-in, if I had to have a guess it would probably be the same as hooking up a normal event with C#:
visioApplication.SelectionChanged += new EventHandler(Application_SelectionChanged);<br />
<br />
private void Application_SelectionChanged(Office.Interop.Visio.Window window)<br />
{<br />
NumOfShapes = window.Selection.Count;<br />
MyShape = mywindow.Selection[1];<br />
ReadANamedCustomProperty(MyShape, "HoursPerWeek");<br />
}

In the code below I created a class(Listings) to hold three stings.
I Also have a ArrayList of the class.
I can add items, can see the data in the watch window and I can use a foreach and see all elements of the arraylist, but I cant figure out how to read the data in the first element of the arraylist.
Thanks for your help.
Mitchell
public class TestArrayList
{
public TestArrayList()
{}
private ArrayList arrListings = new ArrayList();
public void ClearList()
{
arrListings.Clear();
}
public void AddListing(string Name, string Address, string Phone)
{
arrListings.Add(new Listings(Name,Address,Phone));
}
public string getFirstListing()
{
return "?"; //What here to return Name for First item in ArrLst?
}
public class Listings
{
private string x_name;
private string x_address;
private string x_phone;
public Listings()
{}
public Listings(string Name, string Address, string Phone)
{
x_name=Name;
x_address=Address;
x_phone=Phone;
}
public string Name
{
get {return x_name;}
set {x_name = value;}
}
public string Address
{
get {return x_address;}
set {x_address = value;}
}
public string Phone
{
get {return x_phone;}
set {x_phone = value;}
}
}//end listings structure
}
}

You can use the ArrayLists Item property (see MSDN[^])
public string getFirstListing()<br />
{<br />
if (arrListings.Count == 0)<br />
{<br />
return null;<br />
}<br />
<br />
Listings list = (Listings) arrListings[0];<br />
return list.Name;<br />
<br />
return ((Listings) arrListings[0]).Name;<br />
}

I am looking for a reliable commercial or open source .NET library (preferrably) that allows loading SVGs, drawing them, programatically reading and editing them (through SVG DOM), saving them.
I am aware of the following package:
- MobiForm SVG (commercial, but is being discontinued)
- SvgNet (open source)
- Svg# (open source)
- Librsvg (open source)
- Batik (open source)
If you have used any of the above, please let me know about your experience with it. Also please let me know if you have used one that is not in the above list.
We will be building a commercial application that uses the chosen SVG component.
Regards,
Victor

Ok, I'm trying to create a new interface for an existing program. Basically I want to get information (pictures, text) and port it into a new window in a different format. I've come to realize that screen scraping is probably my best bet.
My problems are:
How do I go about screen scraping?
All I can find involves scraping from webpages, this is a windows application.
Is there some way to get a "Window ID" to identify which screen I'm scraping from?
Does the screen I'm using need to be on top? because I am creating a new interface because I want to use it.
Is there a better way to go about this?
Any advice on where to begin?
thanks,
jack

This is a perticularly troublesome issue since you are dealing with a windows application you want to scrape the data from. You can get the window handle! It is kind of involved but you can get it from it's location, or, you can get it from the module handle but you'll need to use windows API which involves some interop. In the end, you might not even be able to get the information depending on if standard windows controls are used or not. Assuming you have the window handle and that the data you are getting is in a standard list box, you can get at it. You mentioned picures though and I know of no non-convoluted way to scrape that. You can get a binary image right off the screen but the window will need to be made topmost, but what if another window overlaps between the time you bring it to the top and you start scraping? Screen scraping is generally reserved for application where data is in text that is rendered to a destination that supports reading it back as text. In the GUI world you'll need to rely on asking some control for that information and that may or may not be possible, depending on the control which rendered it.
If possible, I'd look at getting at the data in some other way, perhaps its storage medium?
Probably not much help but...
