I am having trouble with a socket client application written in vb.net using Visual Studio 2005. The client connects to a C language socket server that is running on OpenVMS. The problem that I have is that when the server sends a packet, the client does not receive the last byte (of every packet!). I can dump the packets on the network and the data is all there. My current solution is to keep my socket messages short (247 bytes) and send one extra byte past the end of my data.
I would like to include more information in my messages and I cannot find a way to make this work. If I knew 100% how long the packets will be on the network, I could work around this by including an extra byte in just the right places. However, I don't want to make any assumptions about the length of the packets.
Here is a sample of my client receive code:
Private Sub ReceiveMsg()
Dim nTotalBytes As Integer
Dim nNumBytes As Integer

I'm running this on Microsoft Visual Basic 2008 I want to make a program with 2 forms, one with buttons, the other that will just hold picture boxes, which are created when those buttons are clicked. Once those picture boxes are placed on the second form, I want to be able to drag and drop them to move them anywhere on that second form.
I have it "working" as of right now, but it's really glitchy. Almost as if it can't keep up with my mouse movement. But I'm not moving THAT fast so I can only assume that something is wrong.The buttons work so I won't post that code here but the following code is for the second form and what I'm using to control the picture boxes.
Public Class Form2
Private counter As Integer
Private boxCounter As Integer
Private list As New ArrayList

I am in a visual basics 2008 class for my MIS degree. This is the beginners class. We were instructed to build a program that calculates a score average. However, we get extra credit if we figure out how to drop the lowest test score. I do not know how to do this. The teacher won't help with the extra credit. I will post my code.

Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.
I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.
I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?

View 1 RepliesAn order can have many OrderDetails, and a Product can be on many different orders. The OrderDetail table just has the OrderID and productID, so there is essentially a many-to-many between order and product).I have a form for the user to enter a new order. I want to have an unbound box that contains the names of all the products, and to be able to drag these names into a box under the order, to add a new OrderDetail record using the productID of the dragged order along with our orderID.
View 1 RepliesI am dragging and dropping data from a combobox to a datagrid. I'm using VS2010 VB for a windows app. My problem is that the DragDrop event for the datagrid gives x,y mouse positions that are relative to the physical screen that I am using, not the datagrid. So when I use hittest to calculate the row and column the result is out of the bounds of the datagrid. If I manually drag the form around the physical panel, the x,,y coordinates on the dragdrop event chage accordingly. This is really strange.
View 2 RepliesScenario:I am attempting to perform some work on files (rename/delete) in folder, usually in a network location. Because the location of products folder is not critical, it's rarely ever in the same place on different networks. A simple shortcut on the client machine is all that's required from the client perspective and the rest of the product is self contained on the server somewhere. To run the 'fix' my small application will perform quickly and easily, I need to parse the path held in the target box of the .lnk. Then perform ifexists for a specific file and then do my renaming/deleting.
To keep it as simple as possible, the end user should just 'drop' the shortcut onto my form then click 'fix'.The problem: How in the heavens can I retrieve the target location from the .lnk into a string without windows scripting host?

View 1 RepliesMake a folder, based on an input file - example :
You have a file named Movie1.avi on your desktop, u open up the program (that I want to make) and then simply drag drop that file into a box area, and then the program will create a folder, with the same name as the input file, but without the extension (folder name Movie1) and then automatically put that file into the folder it just created.
The new folder will be created in the same dir as the input file.
Multiple file support - is NOT needed.

View 3 RepliesI am trying to control the security board using the Windows Firewall which connects to my server that was made in VB.Net. My only problem is when I open the Windows Firewall my server crashes. It also displays this error: "Error, win%fir%90y4e does not support this server. upgrade you version of Winsock.". So I upgraded myself to the latest Winsock that there is out there. After doing so I try again and my server still crashes, but this time with a different error. The error this time was the following: "Error, no client is available for win%fir%90y4e. try again later.". What do I do?

I built a WCF service that exposes itself for a web application, it accepts an object and prints the data on the clients machine. Works fine on my development machine, and the service is up and running on any machine i install it on. I can enter ip address in clients machine web browser and see it is running. Problem is when i send the object to the clients machine it returns an error, that sounds like it could be because of the clients windows firewall. Where would i start at to deal with this problem ?There was no endpoint listening at http://192.168.1.168:2202/PrintLabel that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
