What do you mean, locally?
I think this error can happen when you dont have appropriate permissions, or maybe Word is not installed at all?
Take a look at Control Panels -> Administration tool -> Component Services -> dunno somewhere you should find settings for Word DCOM model. Good luck.

Hi friends..
string str="ABC";
this means that we are assigning value to the object str of string class..right?But whn we are instantiating some class then we are assigning values to the feilds of that class(ex:Employee_1.Name="xyz",Employee_1.Id=1234,etc where Employee_1 is an object of class Employee)..thn how things are working differently for string class..I think this has to do something with user defined and predefined reference data types..

str variable has the memory address of the location where "rahul" is stored.
The value assigned to a string variable is stored in the heap, and its address is stored in the stack.

This is not C. You're creating an instance of a class, which then contains the value "rahul". If you create a byte array, you can create the same effect as a char * in C, where you're storing the values themselves. Of course, .NET can move your objects in memory, so you'd have to pin the memory before being sure the string will stay in the same location.

The most idiotic and selfish thing to do in these forums is to delete your question after getting the answer!!
This's a good reason why we have to quote at least part of the question!!

hey..
i am currently working on a C#/openGL drawing application.....drawing is great but I need to incorporate functionality to select and edit lines with the help of mouse...plz suggest good tutorials from your expereince
cheers

Because a line is not an object, you will have to write your selection process from the ground up. You will have to register the points contained by lines (perhaps recognizing members from end points for instance); detect clicks or other process you might provide for selecting lines; and then perhaps re-draw the line/polygon/etc... to indicate it has been selected. A process you might use to select graphic elements could be to iterate through a list of the elements your processes have drawn, re-drawing each to indicate selection as the list is iterated by arrow keys, navigation buttons, or whatever.

Hello everyone,
I need to add the option of uploading image into a remote database server to my Windows Application. I have been reading about it and it appears there are different ways to approach this. So far two of the ways that I find intresting are:
1- save the image in the database as type BLOB.
2- upload the file, save it to disk, but store the filename in the database.
I was wondering if for option 2 I have to create a new Ftp instance and then FTP the file to the remote server?!!!
Any ways, I have no clue what so ever and any information regarding uploading images from a Windows Application will be appriciated.
Thank you very much and have a great day.

1. In the case of using a BLOB, your server side application or RDBMS will be used to store the image to the BLOB field.
2. In the case of uploading the file and storing a reference to the file in your table, yes, you need likewise to send the file to a server side application. It will be the responsibility of the server side application to store the file and register a reference by whatever system is necessary for retrieving the file. Sometimes such resources are distributed to many locations. For instance, a client application might keep the original copy it receives in response to its first request for the file. Later, if it needs the file again, the server application might compare the last modified timestamp of the source file, and only return a message that the copy the client has is current. You would do this for instance to minimize network bandwidth consumption.

Hi,
I have a ListView to which I would like to add a ContextMenu. There are three different scenarios which I would like to cater for. The first scenario is when the user right clicks in an empty area of the ListView - I want a specific set of menu items displayed. The second scenario is when the user right clicks on one single item in the ListView - I want to show a menu which has some options enabled/disabled due to the actual data object which the user selected. The third scenario is when the user multiply selects rows in the ListView, and right clicks on an item - I want to show a menu which has only some of the items displayed, based on the which items the user has selected.
I also have exactly the same problem with TreeView.
Please help me !!!

Your problem is conceptualization:
If and only if you can detect the regions which you want to process, can you pull off your job. You can detect whether single or multiple items are selected and which mouse button is pressed, so you can pull of this much of your job. But detecting a click in an "empty area" may not be practical.
You have to work with the component however the component is designed to work with you.

In our upcoming CMS (zeta producer 8 [^]), I am doing this for both <a href = "http://msdn2.microsoft.com/en-us/library/system.windows.forms.treeview.aspx" rel="nofollow">TreeView</a> [<a href = "http://msdn2.microsoft.com/en-us/library/system.windows.forms.treeview.aspx" target = "_blank" rel="nofollow">^</a>] and <a href = "http://msdn2.microsoft.com/en-us/library/system.windows.forms.listview.aspx" rel="nofollow">ListView</a> [<a href = "http://msdn2.microsoft.com/en-us/library/system.windows.forms.listview.aspx" target = "_blank" rel="nofollow">^</a>] as you described.
I do handle the SelectedIndexChanged event of the ListView and TreeView and change the ContextMenuStrip property to either of 3 predefined ContextMenuStrip controls.
In Addition I enable/disable menu items in those ContextMenuStrips based on the content of the selection (i.e. whether a single or multiple items are shown).
This works exactly the same for both TreeView and ListView.

i've a cross thread problem
i searched the net alot and i still can't solve it
here is a complete sample of the code
WaitCallback callback ;string username;
fn(object sender,eventargs e )
{
callback = delegate(object state) { this.ExcuteFN(); };
}
void ExcuteFN()
{
//MethodInvoker.Combine(callback);
try{
this.usertableadapter.insert(textbox2.text,combox1.selectedvalue);}catch(){}
finally{textbox1.clear();}
}
the problem that another thread is accessing the control that created by main thread
ofcourse i don't want the dirty solution to stop the control check
i tried the
MethodInvoker.Combine(callback);but no way, i tried many other solution but also no way
any solution plz provide full details

I use the (from memory) WorkerThread class all the time now. It has callbacks to the main thread which I can use to do any UI updates that need to happen during and after the thread.
