I think you need to add your program in the context menu like the way if you right click on a text file "Notepad" application comes as an option.
You can try out the option mentioned here[^] (thoug i did not get a chance to veify  ).
I found few products are also available [^]which you can add while packaging your installer and obviously it should permit your budget  .
Keep me posted if you need any further help.

Thanks Arindam, I checked out that first link and I understand what he was talking about, however where in my installation package do I add that information? I get the whole merge module business but where or how does that get edited? I have checked the MSDN but either I do not know what to search for or how to phrase my question or simply not experienced enough (on a 4 level scale, I figure myself to be a level 2 programmer...I can code in c++ and vb and a little win32 and put together a simple install package, but that's it) and MSDN only gives a skeleton outline of the process of creating a merge module.
If I have to code it out directly, then that is fine. I am not asking for a direct step-by-step answer, only to be pointed in the right direction. Thanks a million!

I think probably you understand that you need to have something registry entry for your application (something like below one)
HKEY_CLASSES_ROOT\<file type>\shell\<display text>\command
Now your point is how to do that?
I think this MSDN article[^] might help you.
Keep me posted if this does not help you.

Dear Developer,
I'm very much concern linq versus stored procedures. can you give an idea where is the best tools to data execution and distribution more faster
TY

Are you asking how to use stored procedures in Linq to Sql? AFAIK, Entity Framework is replacing Linq to SQL. You should take a look at entity framework rather than learning obsolete framework.

What do you mean by that?
IMO, frameworks like Linq to SQL and Entity framework provides a clean abstraction over the data access. It helps you to write maintainable and readable code than giving super fast performance. You get much better performance when you work directly with commands and data readers. My suggestion is to write maintainable code than thinking about performance.

The SQL generated by EF is sometimes not the best from a performance basis so you may need to use stored procs in conjunction to get the best from it.
only two letters away from being an asset

Hi I have a service written in Visual C++ 6 that needs to interact with an application written in vb.net. In my service I have used :
<b>DWORD mymsg=RegisterWindowMessage("my_message")</b>
to register a unique custom message.
I then use:
<b>BOOL b=SendNotifyMessage(HWND_BROADCAST,mymsg,NULL,NULL)</b>
to broadcast my message. However, I can't seem to be able to capture this message in the Windowproc function of my vb.net application.
<b>Private Declare Function RegisterWindowMessage Lib "user32" Alias "RegisterWindowMessageA" (ByVal lpString As String) As Integer
Dim mymsg As Integer = RegisterWindowMessage("my_message")
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
if m.Msg=mymsg then
--do something--
end if
end sub</b>
Please help! 
P.S.:I need to show a pop up in my .net application when it receives this message. The message values have all registered properly in both applications and are returned to be the same when I print them. Also the SendNotitfyMessage in my service returns a non zero value(supposed to indicate success). What do I do?? What am I doing wrong? Is there something wrong with my message receiving code in vb.net?

Try changing your WndProc declaration to:
<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> _
Protected Overrides Sub WndProc(ByRef m As Message)

Thanks for the suggestion but I tried it and it didn't really work. I don't think it's a security issue. I doubt that.

Erm I just read your post again and see you are talking about a "service". If you mean a windows system service, then what Mark said is right: you shouldn't be using windows messages to exchange information - follow his advice and use some other form of inter process communications.

A Windows service application? If so, services run in a different desktop
so you may want to use a more suitable IPC mechanism instead of window messages
which don't cross the desktop boundary.

Are you trying to say that since the service (SYSTEM acct) is running under a different user context than the application, that the messages won't reach the application from the service? Because my application can communicate via messages with my service using its handle.I've already done that. This implies I can only communicate from the app. to the service and not the other way around. Or does it mean that I can only use handles to communicate one-to-one and broadcasting won't work? Neither of the two seem to make sense to me.
As for another way, I could use custom named events but I've already done one way via messages and I thought I could do the same thing in the other direction.
If there's something else you were trying to suggest then I'm sorry I don't think I quite understood you.

Hi thanks for all the advice. I've managed to take care of it. I had to make the service interactive in order to make my application visible to it and I found no other way of making it visible due to the different user contexts. So you were right

Greetings.
I'm trying to communicate between desktop PC and Windows CE 5.0 device connected by usb (cradle).
I feel like I'm missing something obvious, because I can't find how to establish connection between them. What namespace to look? I just want simple communication: connect, exchange some data, disconnect. Sockets are more then enough, but what address should I access? The one assigned by usb connection on handheld is not accessible on desktop machine.
Communication should be initiated from desktop PC.
My handheld is running Windows CE 5.0 with .NET Compact Framework 2.0
Please point me to the right direction

Maybe take a look at the rapi.dll and see if it does what you need, you need to p/invoke the methodes.

how to perform calculations in datagridview columns
(adding two columns and result in new column)
can any one suggest me any site
thanks in advance
|
|

Some of the gurus on here will probably have a better idea for this but this is what I would try:
Dim myCol As New DataGridViewColumn ' I think this is the type. My code was an image column<br />
myCol.Name = "colname"<br />
dgvMyGrid.Columns.Insert(1, myCol)
Then you'll need to access the values of the numbers you need to add and the column where the result should go. I do most of my processing in my OnCellFormatting event. And in there, I access the values of the current row's items with something like this:
(sender.Rows(e.RowIndex).Cells(14).Value <br />
Of course, you'll need to know your column's number. And don't forget to account for the one you entered.
Hope this helps.
