Hello All,
I have a dotnet windows application in which i am using crystal reports, built using vs 2005, installed on a machine using click once setting. Till now the application is working fine. but when i am migrating my application from vs 2005 to 2010 and deploying it onto the test environment, at the time when client is opening the application through application shortcut ,the crystal report runtime for vs 2010 is not installing on the client machine. However i have mentioned it as a prerequisite and also the crystal report runtime setup is there in the Application deployed location.
Help really appreciated.
Regards,
Ashish

Due to my current work, I need to display a plain image in a WinForms control (based on a map, but not from Bing / Google / other APIs) such as a JPEG or PNG in which I need to define/show points of interest. It will also be good to allow showing/hiding these layers of information (e.g. basic plain JPEG map in one layer, points of interest in another layer and dangerous points in a third layer) based on the user's criteria independently as well as allow clicking on these points.
In the past, I have performed such a similar work on a web environment by using OpenLayers, which provides a functionality (I think via a plugin/trunk) to work with plain images instead of retrieving the data from a devoted server.
But now, I'm a bit lost. I have been taking a look at SharpMap + GdalRasterLayer, but I have not been able to find any good tutorial to perform something similar to what I pretend. Maybe too much complicated for what I pretend, and of course not the target of these gis-based libraries.
I hope someone can help me;
Thanks in advance.

I don't know of any 3rd. party library for this specific purpose, but, I think a lot of what you may do will depend on the nature of the whatever-objects you need to overlay on top of the map to define your "points of interest." Can you describe those objects further: are they icons ? graphic files ? Do they function as Controls, meaning: if you hover over them, click on them, etc., some action is performed ?
And, the solution will also depend on what facilities you provide for viewing the underlying map: will the user be able to pan, zoom ? I would guess you'd implement that which requires re-calculation of which overlay objects will appear, and where they will appear.
You can certainly create transparent Forms in WinForms and carefully position them over some base Form (or Panel, or other ContainerControl, in a base Form) that contains you map as a BackGroundImage. Those transparent Forms can, of course, have objects in them that are not transparent.
If you want to look further into doing this yourself in C#, then please post a more complete specification here.
good luck, Bill

Long time ago, I made an application near to your requirements. The main design was:
- An abstract base Shape class having some methods like a void Render(Graphics) and a method for hit testing,bool HitTest(Point).
- Shape classes for custom shapes that are needed on each layer; shapes like point, line, icon, path, etc that inherit from abstract Shape class.
- Each derived shape has its own properties and overrides Render method and renders itself on the graphics object; also overrides HitTest method to check if it contains a point.
- A Layer class that contains a List of Shapes and a void Render(Graphics) and calls render method of each shape. (You can restrict each layer to specific types of shapes, you can implement z-order management for shapes, etc)
- A Map class having and Image and a List<Shapes> and Save and Load to/from file. (You can handle Active layer and active shape easily.)
- A custom control that has a Map property. This control is responsible for rendering layers and handling user mouse interaction and update layers. This control overrides OnPaint and mouse events and enables double buffering.
Hope this idea helps you.

Instead of disabling the menu-item, I'd recommend not creating it in the first place.

Try creating a variable in the login form, when any of them logs in assign a value to that variable. Note: the value assigned should be different depending on who logged in. E.g (variable_name = 1..when admin logs in, variable_name = 2..when user logs in ). On the load event of the main form use an if statement to check the value of that variable. Depending on the value of the variable disable the menustrip item using the its name. Example when a normal user logs in
If(variable_name=1)
{
Menustripitem_name.enable=false;
}
Remember to declare the variables for validation as static variables in the login form so as to access it in the mainform.
Hope that works

Thanks.
I also solve this problem but my procedure is different first i MDI Parent form menustrip itme property change the modifier it declared public and then i access this menu strip in other form like login form.
step:1
menustripitem property = public
step:2
creating an object the login form
step:3
object.menustripitem.Enabled = false;
it working properly

you also realise that you can merge menu's from the child forms into the parent container?

check it userwise
if(user =="admin"){
menu.IsEnable=true;
}
else {menu.IsEnable=false;}
something like this

Try making a Boolean variable.
On login, the app must determine if the logged in user is admin or not.
Then, set the appropriate values.
On login:
If user is admin: adminbool = true
else
adminbool = false
On form_load
If(adminbool=false)
{
Menustripitem_name.enable=false;
}
else
{
Menustripitem_name.enable=true;
}
You get the idea, right?

Hi,
We have a Windows Forms project with quite a few flatstyle buttons.
When we disable the buttons, the colors of the buttons are changed automatically 
Is it possible to override this somehow, so we can control the colors ourselves?
Thanks,
Karl

You could create your own buttons, the simplest way is to inherit from Button and override some functions:
public class BernieButton : Button
{
protected override void OnEnabledChanged(EventArgs e)
{
base.OnEnabledChanged(e);
....
}
}
