how to forcibly make the MdiChildren Menu list update?

View 7 RepliesI have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.
View 4 RepliesHow do I make a menu item on a menu strip link to another windows form (like a menu item that links to an about page already created in the project). I know that every coder knows how to do this, but i've read most of the instructions in the world for Visual Basic coding, but can't find ANYTHING I know coding fairly well, so I can modify it, but I can't create it my self.
View 4 RepliesI've been working on an application recently and it has exceeded the scope of a single form.I decided that it would be a good time to use an MDI container and split the interface up over a number of different child forms.As the application was written, there were a few different classes that were being instanciated on the original form.I've migrated these over to the MDI parent form so that I can allow all of the children to interact with them.The route that I'm going down right now is raising events on the child forms and watching for them on the MDI parent.The parent form is then doing whatever the child did to the instanciated classes in the past.

I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while or pass a large amt of data to a web service in a dataset, I get the subject error.The error seems to occur in < 1 min, which is far less than the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server.It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server:System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the rem
View 3 RepliesI have an application that copies a file from a network/internet location. I am trying to catch the exception for when the network connection becomes unavailable (or internet goes down). Currently i catch the exception "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host." which occurs on the bold, underline line below.The issue i have is i try and attempt the operation to continue doing what it was doing by resetting variables and then reassigning them to continue reading the stream but cant get past this error. The only way to go past it is to stop and start the application which is not what im after. [code]

Below error is thrown in a already opened program which connects to different database
A transport-level error has occurred when sending the request to the server.
(provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
Program details: code done using vb.net with MSSQL 2008 as back-end
Two instance of same exe where running simultaneously in same PC but error was thrown only by one instance Program uses both sqlconnection(ADO.NET) and ADODB connection(upgraded from VB6) and the error is thrown by both types of connection. If the error is due to network problem with the server then why few programs work fine? I am not able to trace the reason for this behavior of the program. Can I know why this error occurs and why only in few programs of same instance.

View 5 RepliesI have a datagridview (windows forms) that is inside an mdiChild form. The custom format is given by a "for" instance, something like this:
For row As Integer = 0 To .Rows.Count - 1
If .Rows(row).Cells("someNumber").Value = 0 Then
.Rows(row).DefaultCellStyle.BackColor = Color.DarkSeaGreen
End If
Next
So, for every row in the grid that you find, if ther value in the "somenumber" =0 paint the whole row green. Problem is, if I put the form OUTSIDE of the MDIParent - just put frmMyform.show() in my btn that calls the form-, the grid WILL apply the format; If I call it like frmMyform.mdiparent = frmMdi, then frmMyform.show, the grid WILL NOT apply the format.
I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

how actually antivirus, WinRar and other applications can list their application in context menu? I'm developing an application using vb.net and I want to list my application in that menu. look at this screenshot...
i found this article to solve that problem >> Context Menus in VB.NET. However, the context menu only appear within the form.
For example, WinRar; you can see that application be listed in the context menu whenever you right-click on any file. I want to do like that... but how?

As you can see from the screen shot I have managed to get MDI Parents / Child forms working, and managed there to be a menu option on the Parent form that displays all the Child forms opened at the time. What I was wondering, and as of yet through research haven't discovered, is there a way when the list of windows is created, if a user highlights any child in the list it opens a sub-menu from its name (eg. Rename Window, Center Window, etc).

I have a tcp server that uses TCPListener and the async method BeginAcceptTCPClient:
Imports System.Net.Sockets
Imports System.Threading
Imports System.Net
Public Class TCPServer
[Code]...
My problem is that infrequently, I get an exception in the HandleAsyncConnection method:"An existing connection was forcibly closed by the remote host" right at the EndAcceptTCPClient method. At this point, the TCPListener seems to stop listening. The problem is that I can't test this easily, as it only happens on a remote test VM and only once every 24 hours or so. If I knew how to recreate the error with a test client, I would be able to figure this out. Wireshark shows a reset [RST] packet being sent at around the time of the exception. So I either need to know how to handle the exception, or how to recreate the problem with a test client.
