Hi,
You can use the Parse or TryParse methods of the number types to do the conversion. This fragment in c# should get you started.
String userInput = "ab7f";
Int64 value = Int64.Parse(userInput, System.Globalization.NumberStyles.HexNumber);

What do want to convert it to?
The assumption is that it's to integer but it could be to character or binary or unicode.
E.g. 4C hex goes to:
integer 76
binary 01001100
ASCII L
EBCDIC <<br mode="hold" />
You really need to be specific when asking questions.

I’m stuck on how to enter a HEX number into a text box
|
|
|
|
|
Strictly speaking, what you are asking for is actually not possible. There is nu such thing as a hexadecimal numbe, you either have a number or the hexadecimal textual representation of a number. Converting the textual representation into a number is called parsing.
Entering the hexadecimal textual representation of the number in a textbox is easy. Make sure that the textbox has focus (you will see the blinking caret in the tectbox), then you just push keys on the keyboard to enter characters in the textbox. Valid characters for the hexadecimal representation are the digits 0 to 9 and the letters A to F. The letters can be either upper case or lower case.
Despite everything, the person most likely to be fooling you next is yourself.

Hi Everyone,
Can anyone guide me to install a vb6 application in a dotnet machiene.
Regards,
Manowj

|
|
Can you please elaborate : what are trying to do and where exactly you are facing problem 
|
|
|
|
|
The fact it has the .net framework installed makes no difference to a vb6 app. The two are not related, just install the app in the normal way.

Please use profiling tools any of following tools :
CLR Profiler[^]
NDepends[^]
By using above tools, you will come to know expensive part of code. Then you can try to optimize that code.

But how can i know in which module is generating that problem.and I m using on error resume next for error resloving.

Thats what the profiling tools show you.

Nothing to do with profiling, but it could mean you are not freeing up resources if you get an error.

 Have you tried to use any of mentioned tool. Better to try out, You will granular report on which function or module is taking most of CPU time.

Comment out your error handlers. It appears that your code is generating errors in a loop, but your "error handling" code is burying the errors so you can't see them.

That's not "error resolving", that's burying the errors. If you're using "On Error..." in VB.NET code, you're digging yourself a hole. That only exists for VB6 backwards compatiblity. I highly recommend re-writing the code to use Try/Catch blocks instead.

Hi Sir,
My application normally takes CPU usage 0 - 5 in administrator account but in Guest account it takes 10- to 46.
please suggest me what is the problem

You're using VB.NET and the old VB6 error handling?? Not a good idea...
Anyway, it's impossible to tell you what the problem is because we haven't seen your code. Don't post the entire project.
What you have to do is use a code profiler to find out where the problem is. Since the app works as an admin and bogs down as a normal user, I'd say you're doing something that requires admin rights, but your error handling is written so badly, it's burying all the errors.

I have tried to copy from Sheets("S") rows meeting condition and copy those rows to a new sheet, but not able to get the code to work. Here is my code. What could I be doing wrong?
Here is the spreadsheet fields.

I have a multiline textbox control on a form. When a user focuses on the textbox I want to check and see if a certain string (user's name and todays date) are in the textbox. If not, I want to automatically add the user's name and todays date to the end of the textbox and position the curor and scroll to the bottom. I am having trouble with the scrolling/cursor positioning part. My code will scroll down, but the cursor ends up moving to where ever the user clicked in the textbox. Does anyone know of a way to ignore where they clicked so as to override where the cursor goes? Is there another event that fires that I can grab? Am I missing something obvious here?
Private Sub txtInput_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtInput.GotFocus
Dim strAutoLabel As String = gblstrUserName.Trim & " - " & Now.ToString("M/d/yy")
'If the textbox does not contain the auto label, add it
If Not txtInput.Text.Contains(strAutoLabel) Then
If txtInput.Text.Trim.Length <> 0 Then txtInput.Text &= vbCrLf & vbCrLf
txtInput.Text &= strAutoLabel & vbCrLf
txtInput.SelectionStart = txtInput.Text.Length - 1
txtInput.ScrollToCaret()
End If
End Sub
I'd appreciate any help or advice you can give me.
