Exception Error Running App From Network Drive Win7

May 30, 2011

We have a VB.NET applciation that is run from a mapped network drive. This works fine on all PCs expect those with Windows 7, on those we get the following: "application generated an exception that cannot be handled" System.Security.SecurityException was unhandled If the application folder is copied locally and run from there it works fine. I assume it is related to Windows 7 netowrk security but not sure how to work around it.

Runtime Error '380':Invalid Property Value

May 2, 2006

A VB5 program I wrote years ago stopped working and is now giving me this error:

Run-time error '380':Invalid property value

I cannot figure out what has changed, since I run that program almost daily.   It was working fine, then stopped (without any changes to the program).   I suspect I may have uninstalled something it uses, but cannot figure out what.When I open the VB5 IDE, I get an error saying:

'c:program filesdevstudiovbComct232.ocx' could not be loaded--Continue Loading Project?

If I say no, it does not load and I cannot see the source code.If I say yes, it does load and I can see the source code but I get weird compiler errors.

Decryption Error : Padding Is Invalid And Cannot Be Removed

Apr 23, 2010

I have been writing a security class in my application, I am able to encrypt the string correctly and without error. However every time when I try to decrypt this string again, i get an error with this as it returns the following Padding is invalid and cannot be removed.

Here is the code:

Public Function DecryptKey(ByVal plainText As SecureString, ByVal key() As Byte, ByVal iv() As Byte) As SecureString



And it provides a stack trace with:

at System.Security.Cryptography.RijndaelManagedTransform.DecryptData(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode paddingMode, Boolean fLast)


I have found simular issues on web, and most of them say that the IV is not the same the encrypted version, but I can confirm that the IV is the same as they both access the exact same variable.

Error : Invalid Cast Exception Was Unhandled

I am getting  Invalid Cast Exception was unhandled.Conversion from String 'abc' to type 'Double' is not valid in the following line!

((xlBook.Worksheets(2).Cells(iRowIndex, iColumnIndex).Value)) = avFoundKeywordds(iSearchText)

The business intent is that user enters the keyword 'abc' and clicks search button . We have defined different keywords in a xls which has 1600 rows and 16 columns . so when finding abc in any of the cells ,it has to return the value of a column#4 where the name is specified !

Dropdownlist Invalid Error Edititem Template Gridview

Sep 15, 2011

Error Dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value I have been banging my head over this error for about a week now. I have searched posted on other forums and still no solution to my issue. I have seen the FindControl being suggested but do not know how to implement this.

Basically I have 2 webmethods that reference 2 datasets which then populate my ajax cascading dropdownlist. In insertmode they work great however in editmode i get the above error.I have removed the selectedvalue and added

DataSource='<%# Bind("intRoom") which works sort of except for the fact that when you click edit it does not retain the original value of that particular record. Other things i have tried are as following:adding the items to the itemcollection of the dropdownlist turning appenddataitems to true on also tried to use the findcontrol but dont understand that punching my monitor and slamming my keyboard

Now I know i could get this to work by using a sqldatasource with some t-sql to get my dropdownlist to work however I thought by reusing my webmethods my code would be more professional. So if there is anyone out there that can help me understand why the value for my dropdownlist is not being populated or does not exist during gridview editing Also will post code if asked not sure what you would like to see rather than posting everything.

Invalid Viewstate Error When Posting Back To Same Page

May 24, 2012

I'm having some issues with an Invalid Viewstate error and I can understand why it's happening but I don't know how to fix it so I'm hoping someone can help.

I have a page which is similar to this /story/?id=123 but I'm using a different page to Server.Transfer to this page.

So I've set up /info to Server.TransferRequest("/story/?id=123") and it works fine until the page does a postback to itself.

We have a login form on this page which simply reloads the page but when it does it seems to add /?id=123 onto the end of the URL so it ends up like this /info/?id=123 thus causing an Invalid Viewstate error.

I've already tried adding EnableViewStateMac="false" - this fixes the error but it doesn't log the user in as expected so it does not give the required result.

Is there a better way to redirect to my page other than Server.TransferRequest but still keeping the nice URL? - I don't want to response.redirect if I can avoid it.

ReadProcessMemory Keeps Returning 0 - Error: INVALID WINDOW HANDLE

Dec 6, 2008

I'm currently developing a little hobby project to display health information in a game on my G15 keyboard through VB.NET. When I use ReadProcessMemory via an API call, it keeps returning zero. The MSDN documentation referred me to use the Marshal.GetLastWin32Error() call to find out what is wrong and it returns 1400: INVALID WINDOW HANDLE.

I am now confused about whether the first argument of the function wants a window handle or a process id. Regardless, I have tried both with FindWindow and hardcoding the process id while the application is running (getting it from task manager). I have tried three different games, Urban Terror, Grand Theft Auto: SA and 3D pinball for windows, getting the memory addresses from an application called Cheat Engine; they all seem to fail. [Code]

VS 2008 Invalid Parameter Error When Trying To Get Favicon In Stream

Aug 24, 2009

I am using VB.Net 2008 Express and trying to build a favorites list for a webbrowser I am working on.I get an invalid parameter error on the line that reads favicon = image.FromStream(stream).[code]the urls are stored in an array after they are taken from an xml file.I checked the url that was being used when the error occurs and it seems fine. I can even navigate to it in IE.The error I get is that "stream" is an invalid parameter, at least that is where it points to.It also shows that stream is a type System.NET.ConnectStream.Stream was originally set to System.IO.Stream.I don't know if this is a problem but it processes several urls before it gets to this one.I am wondering if this may be a permissions issue and the site is blocking the WebRequest or if it is something else.
