Vb - Hex2dec

[Guest Dater_]

Hi.

I have problem with converting Hex to Dec in VB.

I have hex string for example "975D46ED" - in HexDecChar by Ap0x it is "-1755494675" (bad) but in CrackersTool it is "2539472621"(good). Hmm strange...

My code is :

SerialHex = CStr(Blabla1hex) & CStr(Blabla2hex) & CStr(Blabla3hex) Hex2Dec = CLng("&H" + SerialHex)Text2.Text = Hex2Dec

And my app give me...bad "-1755494675" not good "2539472621".

Can anyone help ?

I have no idea about vb coding ,but you are getting the result as signed #, just get the output as unsigned # , you will have the desired result. Regards.

Dater,

Try the following:

Function LongToUnsigned(Value As Long) As Double
	If Value < 0 Then
		LongToUnsigned = Value + 4294967296#
	Else
		LongToUnsigned = Value
	End If
End Function'Use the function like this in your code
Text2.Text = LongToUnsigned(Hex2Dec)

Happy Coding,

Thanks guys.

Napalm this is my working code:

EndString = CStr(Looop4bHex) & CStr(Looop4cHex) & CStr(Looop4dHex) & CStr(EndAlgoHex)Hex2Dec = CLng("&H" + EndString)Text2.Text = LongToUnsigned(Hex2Dec)End SubFunction LongToUnsigned(Value As Long) As Double
	If Value < 0 Then
		LongToUnsigned = Value + 4294967296#
	Else
		LongToUnsigned = Value
	End If
End Function

This converts "975D46ED" to "2539472621" and from other 5lenght names too...But not for all for example for "david" returns me "Runtime error '6': Overflow"

So my next question is - it is depend to "4294967296#" from code ?
