I have a Form with 4 Text Boxes, 1 label and one button. What I need to do is: Make all the text boxes and label only except Hexadecimal inputs.when I press Button1
Label1 = TextBox1 AND TextBox2 ^ TextBox3 MOD TextBox4
Once again every all the numbers are in Hexadecimal format.
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?

View 16 RepliesA 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.

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:

Try

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.

If

Then
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 !
