Exception Of Type 'System.ComponentModel.Win32Exception' Occurred In System.Drawing.dll

Oct 14, 2011

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.

Compile Error: Type 'System.IO.FileFormatException' Is Not Defined

Feb 14, 2011

I am writing some simple utility applications in VB.NET. I am using Visual Studio 2010 Express.I'm trying to throw a FileFormatException exception in my code if a user specifies a file that has the wrong extension. Documentation indicates that this exception has been around since .NET 3.0. See

[URL]

However, Visual Studio gives me an error saying that System.IO.FileFormatException is not defined. It's not a typo, either. FileFormatException appears in the object browser in System.IO, but doesn't appear in the Intellisense drop down when I type System.IO.File.

Here is my simple function:

Function ValidateDBFile(ByVal DbFilePath As String) As Boolean
ValidateDBFile = False
If IO.File.Exists(DbFilePath) Then
Dim flInfo As New IO.FileInfo(DbFilePath)

VS 2010 : Show Message Box Error If System.componentmodel.win32exception Occurs?

May 16, 2012

I created a simple program which basically launches programs installed on 32-bit system in the C:Program Files directory. I purposely put an .exe line of code in the compiler but that .exe wasn't installed on the system, I was expecting for an error when I tried to click the launch button and I did. NOTE: I already have a beginning If statement and that program is actually installed in the system, works perfectly no errors appearing.

ElseIf lstMultimedia.SelectedItem = "HyperCam" Then Process.Start("C:Program FilesHyperCam 2HyCam2.exe") 'this program doesn't exist in the system"

When the error appeared I looked at it in detail and found it was a system.componentmodel.win32exception type of error, I'm guessing that means a file doesn't exist in the directory I specified therefore the program displays an error.Now what I want to do is display a message box saying along the lines "This program cannot be found in your system" or something like that. But I don't know what the actual syntax/code for it, so far from thinking I have this.

Else : lstMultimedia.SelectedItem = 'no idea what to put here Then MessageBox.Show("This application cannot be found in your system or is installed in a different directory", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If

Dynamic Type Definition - Error: Type PropertyType Is Not Defined

Mar 11, 2011

I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]

Type 'System.drawing.bitmap' Is Not Defined

Jun 15, 2010

I', working on a program where there are several projects within a solution. The solution contains a forms application, a couple of class libraries, and a public interface.I'm running into a strange problem where I can access the system.drawing.bitmap namespace from the main form and from one of the class libraries, but when I try to access it from the other class library or the interface, it tells me it is not defined. I've tried importing it, and calling it directly with no luck.

I'm trying to implement the GetHttpContext function from HtmlHelperTest.cs in VB.NET using Rhino Mocks, but I'm getting "Type 'HttpContextBase' is not defined." The compiler suggests changing it to HttpContext, but when I do that I get a run time error that a sealed class cannot be mocked.My test project references System.Web and also imports that namespace. Is there something else I need to do in order to get the HttpContextBase type to be visible to the code I'm witting?
