I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing)
Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
Ok, so I got everything working except for one thing. My program stores text in a settings files (which it saves to and encrypts to wonderfully), but it will only work once. For example, I type in an author, title and body, and click Publish, it publishes and is labeled with a "1.". Restarting the application, you get the desired effect, a decrypted string from the encrypted settings file, now publish another entry, this makes a new line with "vbNewLine" and then encrypts it, fine and dandy. Now apon opening the application again, you get an error stating "Invalid character in a Base-64 string.". What do I do?

I'm writing a program and it's got a textbox for the user to enter values. Since the textbox text property should only be a "number", my program need to detect invalid charaters like "*/&()$" and tell the user to only enter a number. Does anyone have an idea how to do that?

I am using MS Visual Studio 2205 Version 8.0.50727.42 and MS.Net Framework Version 2.0.50727 SP2 I created a form that requires the user to enter a date into the textbox.I then use the IsDate function to check if the entry is a valid date. IF Not IsDate(fieldname) then send message back to user on form, otherwise continue.If something like this is enterred - 06/090/10 - It passes the IsDate question and of course fails at the database level when inserting to a datetime field. Although there is a three character day, it still passes.

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.

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."

View 4 RepliesI'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.

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.
