Suppress Additional Runtimer Error Messagebox
May 17, 2012
I've run into a couple of errors within my program which reads a text file. When a user clicks a button to read the textfile and an exception is thrown, i have it displayed as a string in a message box, but an additional message box related to runtime error 52 'bad filename or number' has shown up and continues to pop up, even after clicking ok. I am currently working on the error itself in the textfile, but until I can work around all of the variables with reading this file, I was wondering if there is anything I can do to either prevent the runtime error box from popping up or figure out why it's popping up so many times. The really weird thing is sometimes after clicking ok on the initial message box displaying the error string, it won't pop up and other times it does, repeatedly.

I am writing a program that tests our hardware write blocker units.When i send it the command to delete a text file on the device it should ONLY respond with my error message coded with a try...except statement.However the error message seems to be coming from windows 7 when it says "The disk cannot be written to becuase it is write protected. Please remove the write protection from the volume POCKET in drive F:" then it has the buttons Cancel, Try Again and Continue. If i click on Cancel or Continue then my error message comes up.Is there anyway I can suppress the "The disk cannot be written to." error message in Visual Basic 2010?

At run time my application gives an error of "Conversion from type "DBNull" to type "String" is not valid. In my form only one field - Add_info is an optional field which might be filled or not by the user. Before, I had an error when an apostrophe was used so i updated the code as highlighted below. This in return removed the apostrophe error but generated an error whenever there is an empty additional field.
For irow = 0 To QryColSentDataGridView.Rows.Count - 1
If QryColSentDataGridView.Rows(irow).Cells(3).Value = True Then
Try
query = "UPDATE gprdsql.TblCollections SET system_time = '" & _
Labeldate.Text & "' where prac_no ='" & _

I am just doing a bit of error handling. I am just check to make sure that a user has selected an option within a combo box (named cbtitle1) and if option has not been selected throw an error message to tell the user.this if statement is within a save button which once a user click save this error checking runs first then if combo box has an option selected the save goes ahead else it throws an error.I can stop the save function OK but I wanted to put a error icon in with the message box but I get an error when I add it.[code]

I teach VB in college, using the Express edition. I was doing an exercise with my class today using the MessageBox.Show() method in a Windows Forms application. But when I tried entering it in the edit window, it gave me the following error message: 'show' is not a member of 'MessageBox' and it did not show up in the Intellisense box. Most of my students' computers did work with that method, but one or two of them didn't. Meanwhile, I had to revert to the MsgBox() function to get through the exercise.

I have read the MSDN Page on how to suppress messages. I am unable to supress warnings for VS2008. [code] The problem was I had a series of parallel tasks that were dependent on check boxes. I wanted each task to to run simultaneously and then join back. I overcame the warning by using a callback method that decremented until all the call backs completed. [code] The warning was an Uninitialized Variable. Which was not the case as it was dependent on identical if-statements. I opted to use a callback method instead, which turned out to be a better alternative and did not lock up the GUI.

I'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter
encountered a generic type instance in
a signature. Generic code may not be
exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.

when i call GC.ReRegisterForFinalize(obj) and changed my mind, i could call GC.SuppressFinalize(obj) and remove it from the list of object that requests finalization. problem is that when i call GC.ReRegisterForFinalize(obj) twice, it registers the object twice in the finalization-listing. i need to remove the object from the finalization-listing but multiple calls of GC.SuppressFinalize(obj) could not remove obj from the list.also, why is it acceptable for this function to be called SuppresFinalize when after calling it Finalize still occurs?

The data source is an Access 2003 table. I create the table in code and then populate it with 70 rows (each one empty apart from a date field). This unfortunately adds a 71st row (the placeholder for a new table row). Is there a way to stop this row appearing (I don't allow users to add rows anyway, only to edit existing ones, so this final empty row is just untidy and always empty).
Here is the code I use to create the 70 rows:
Conn.Open()
da.Fill(ds)
dsNewRow = ds.Tables(0).NewRow()

I have a TextBox with a list of filenames in it. The user is able to change these file names, but I don't want them to enter invalid characters, such as slashes or question marks.
I've tried two approaches, but they are not satisfactory:
1. Detect the key pressed with the KeyDown event:
Use e.KeyValue to detect keys like Keys.Oem5 (= backslash), then use 'e.SuppressKeyPress = True' to suppress the key.Problem is, with different Keyboard layouts, The Oem5-key isn't always a backslash.
2. Filter the text:
Use the TextChanged event and do a Replace("", "") on the text for every invalid character (there's 9 of them).Of course this will create 'lag' with every keystroke, especially if there's a lot of text. Also the text-cursor and scrollbar will jump back to the top-left when using Replace.
In short: I'm looking for a way to detect the character that is being entered and suppress or remove it when invalid.

Is it possible to prevent compiler warning caused by a static factory method returning an instance of an obsolete class? For example if an instance of an obsolete class (Foo) is created through a static method (Create) a compiler warning is caused by the factory method.
<Obsolete()> _
Public Class Foo
Public Shared Function Create() As Foo
[code]....
In C# the warning could be suppressed using "#pragma warning..." but I don't think that this exists within VB.Net. Migrating to C# is not an option due to business requirements.

I have a listview with four columns (category, name, date , amount). More than one items falls in a category and I mark them with a number. ex - different kinds of pens as no.5. So, if I make an entry of five pens, five "5"s shows up in the category column. I want to display only one "5" in the category column and not to make it crowded with same numbers.

We have a window that has a text box on it that the user must enter in valid data before going on. So we have put in a message box letting the user know that they have to enter in the correct data before going on in the Leave event. That works just fine, but when the user press ALT+F4, or presses the X in the upper right corner of the window it still goes through the event. We would not like for that to happen. When we were using VB6 the same code was in the lost focus, and when the user pressed ALT+F4, and the X the LostFocus event did not fire, or acted like it did not fire. We have also tried moving the code to the Validating event, but it behaives similar to the Leave event? how to close a window, and either have the Leave, LostFocus, and Validating events not fire when the user Presses ALT+F4, or the X

I'm using the webbrowser control in designnmode in VS2008 (vb.net). When I insert new text into the control (from a database) I am promoted if I want to save the changes. How do I suppress this message? In older versions of VS there was a function called 'webbrowser1.silent = True' but that dosent work anymore.
Setting scriptErrosSupressed dosent do the trick.

I've developed a VB.NET console application and tried to use the Build | Publish menu option in Visual Studio 2008 to create a Setup. It works fine except two things:
- when I run the Setup on a Windows 2003 Server, it installs the application in the C:Winntprofiles\Local SettingsApps2.0 directory. How can I configure the setup so that it would prompt for a target directory for the application?
- After the Setup is complete, it starts the application automatically. How can I suppress the auto-start?

I am calling a function in an external dll to a device that runs some firmware. When I call device_open(), the device driver brings up a Warning dialog box that says there is a newer version of the firmware available. How do I suppress the warning dialog box? I am calling this function during an overnight test, so the dialog box prevents my tests from finishing.
