View 4 RepliesI have an ArgumentException was unhandled message: Cannot add or insert the item '1' in more than one place. You must first remove it from its current location or close it. Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

I am writing a small app that is retrieving data from a device connected to a virtual com-port. I connect without problems to the device using the settings 9600-8-N-1.
I need to send the command <esc>MS , the device then sends back the data to a computer. I have tried this using Hyperterminal with success. I also did this with Excel and VBA. I used the MSComm32 Active X control:
MSComm1.Output = Chr$(27) + "M" + "S" + Chr$(13)
Msgbox(MSComm1.Input)
This made the data from the device pop up in a messagebox. I am writing a winforms app in vb.net, using VS2005. I have a form, on which I have a Placed a SerialPort control, named sp. My sample code is as follows:
Private Sub Form1_Load(ByVal
sender As System.Object,
ByVal e
[CODE]...
This returns the error message "Error: expecting a command". I have done som tests in HyperTerminal, and have concluded with:
-If I dont send <esc>, I get error "Expecting a command"
-If I send wrong command (ie MD instead of MS) i get error "Bad command"
Based on this, I suspect that I don't pass the escape character correctly to my device. So I wonder how to do this?

Windows.Forms.DataGridViewTextBoxColumn'.C:SoftwareForm1.vb 1425 19..When the line generating the error is this Me.Name = "Form1".where it has the "Form1" portion underlined in blue.This is a weird error because that line was made by the IDE to say the name of the form and has nothing to do with 'System.Windows.Forms.DataGridViewTextBoxColumn'.I tried saving my progress and restarting the IDE with no luck..Now I cannot even access the form in designer mode,One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.The designer cannot process the code at line 1424: Me.Name = "Form1" The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.

Intellisense highlights no problems and if I Build the web site in VS I get a few warnings about schema information in the web.config (unrelated), otherwise no problem.
I use web methods in a couple of places in the intranet site im working on and they work fine, however one page is constantly throwing a HTTP 401 error every time I try access the web method.
Im not sure how to aproach this issue, I have tried commenting everything out of the web method, and still get the 401 error, even a basic connect to the database just doing SELECT 1 does not show up when I watch the DB with profiler.
My web.config is the same for all pages in the intranet and I cannot see any differences in my ASP.Net page compared to pages where web methods work.[code]...
I've developed a windows service that connects to a database and executes a Stored Procedure when running in debug mode I get the following message: "ContextSwitchDeadlock was detectedMessage: The CLR has been unable to transition from COM context 0x1ffc20 to COM context 0x1ffd90 for 60 seconds. The thread that owns the destinationcontext/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."

I've developed a small HR program that connects to the SQL database which is on the local PC. I've created an ODBC connection to connect to this server and the program works fine. I've used VB 2008 Express edition to develop.
My concern is now I want to install this EXE on a server. ON the server, I've created the same databses and successfully created an ODBC connection on the server as well. Also created one shared folder. I copied all my EXEs and DLLS on to this folder. On the server I was able to execute the program without any problem.
From a remote client, I opened this shared folder and try to execute and it was giving me an ODBC related error, basically it was not able to detect the SQL connection.What I want to achieve is to have one EXE. The program did not throw any other errors.

I am using combobox to populate values from a table, 'Suppliers'. I put this combobox in a form wherein the order details are filled up. This column 'Supplier' is a Foreign Key and set to NotNull in the order detail table. Selecting the first available entry on the combobox gives error 'SupplierID cant be Null' . Selecting the 2nd value is OK, first choosing 2nd and coming back to 1 is also OK. This error comes up when trying to update the database.Even with the first value, the combobox is having a text. I would like to know why the error.

I am having trouble while installing Visual Basic 6.0 . Setup gives message
View 5 RepliesWhy does my VB.Net Project disappear instead of giving an error message?This only started happening recently, but when debugging with Visual Studios instead of getting errors, the program just closes as though the stop button was pressed. This doesn't happen for all error types but it consistently happens if there is some sort of casting error. This is an overly simplified example, but the lines below would cause a program to vanish as soon as they run. Dim i As Integer i = "A" One other interesting part of this is that if that was in a try catch block the error would be caught instead of closing the program.I'm in an office setting so I've been able to test a number of configurations and have found that this problem only affects Windows XP PCs, but not Windows 7. And it consistently happens with Visual Studios 2010 Professional and Ultimate, Visual Studios 2008. Besides that we apparently we all need Windows 7.
