May 2, 2006A 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, 2010I 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
Try
[CODE]...
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)
[CODE]...
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.

If

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, 2011Error 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.

IDE :: ClickOnce Signing Error: Invalid Provider Type Specified
Oct 15, 2010I requested a Code Signing Certificate from my own domain Certification Authority on my Windows 2008 R2 domain controller.
When trying to publish my code to my webserver via Clickonce, it throws "an error occurred while signing: Invalid provider type specified"
In order to get the certificate I duplicated the Code Signing template on my CA, and tried both options available:
1) must use Microsoft Software Key Storage Provider
2) use any provider available locally
algorithm is RSA, key minim size 2048, Hash SHA1, alternative format unchecked
