How can you convert a heximal string to a "normal string"???
For example, I've got a register file which contains the following:
[HKEY_LOCAL_MACHINE\SOFTWARE\ORL\WinVNC3\Default]
"Password"=hex:88,bf,a4,48,1a,4b,4d,4d
So, I want to know how you can convert the heximal string "88,bf,a4,48,1a,4b,4d,4d" into just normal letters and numers...
And I'm using VB 6.0!!!!!

Friend Function HexToStr(ByVal strHex As String) As String
Dim i As Integer
Dim sb As New System.Text.StringBuilder(strHex.Length \ 2)
For i = 0 To strHex.Length - 2 Step 2
sb.Append(Microsoft.VisualBasic.Chr(Convert.ToByte(strHex.Substring(i, 2), 16)))
Next
Return sb.ToString
End Function

Didn't see and unhex functions built in so you have to build one
Private Function unHex(ByVal hexStr As String) As Integer
Dim position As Integer = 1
Dim Result As Integer = 0
While Not position > hexStr.Length
Dim thisChar As Char = Mid(hexStr, position, 1)
Select Case UCase(thisChar)
Case "A"
Result += 10 * (16 ^ (hexStr.Length - position))
Case "B"
Result += 11 * (16 ^ (hexStr.Length - position))
Case "C"
Result += 12 * (16 ^ (hexStr.Length - position))
Case "D"
Result += 13 * (16 ^ (hexStr.Length - position))
Case "E"
Result += 14 * (16 ^ (hexStr.Length - position))
Case "F"
Result += 15 * (16 ^ (hexStr.Length - position))
Case Else
Result += Val(thisChar) * (16 ^ (hexStr.Length - position))
End Select
position += 1
End While
Return Result
End Function
This will take as input a hexstring of any length and give you a result as an integer.
ex. unHex("C17") = 3096
ex. unHex("C17BD") = 792509

One more thing, I'm using VB 6.0, NOT .NET!!!!
And I don't only want them to be converted into numbers, nut just into a string, for example a word!!!

If you trying to get that password, you'll be a little disappointed. At a glance, those numbers are way above the normal ascii characters. Your looking at an encrypted password.

hi,,,
When I made setup of Vb.net project, dotnetfxredist_x86_enu.msm is automatically
included in the setup project. But when I build project it is giving an error saying
" dotNETFXRedist_x86_enu.msm must not be used to redistribute the .NET Framework. Please exclude this merge module."
Setup is built, but as it does not include the framework msm file, .net framework doesnt get
automatically installed on the system nor does the setup run because framework is not
installed. Which is the file to be included so that framework gets installed automatically??
thx,
tasnim

Please help me I lost my night sleep. Tell in simple code.
From my VB client I am passing simple string "Siddharth", to a win32 dll function GetUserName(DATATYPE)(if DAtatype is BSTR or wstring tell me how to convert it into string in dll function declaration). My program should run in 98 as well as NT. I am trying lot of examples but they all are for long. When I convert it to string nothing works out.
VB client
Dim x as string
x = "String"
GetStringFromVb(wstring *)
end
Win32
GetStringFromVb(wstring*)
{
vector MyString;
MyString.push_back(wstring);
{
//..Lot of string manipulation
}
}
One more issue. in the win32 DLL.h if I declare stl parameter, it is not accepted by the compiler.

Where are we? VB6? VB.NET? Are you using Declare to initialize the DLL function call in VB6? Or is this VB.NET? More specific code examples?
Also, for the c++ code, you might try the c++ forum.

Please don't preach. U know it tell and make me thankful or keep your arse away.

Excuse me! He didn't preach anything. He asked you a couple of valid questions about information that you didn't provide in your initial post. Information that is VITAL to answering your question correctly.
Keep his 'arse' away??!!??!!
It's responses like this that make me question why ... nevermind...
You can bet that I won't be helping you anymore. Be nice to the people your asking for help from!

 Yes, perhaps you misinterpreted my inquiry --- and the reference to the c++ forum was a simple suggestion.

First think that comes to mind is you may have to null terminate the string before you send it over.
myString &= chr(0)

VB6 uses BSTR type strings. Which are always Unicode and have their length as the first 4 bytes. When you pass a string to the API ByVal, a copy of the string is automatically made in ASCII (I think!) and a pointer to the copy is actually passed to the function you called. There is no way to "convert" a BSTR into a wString at the function declaration. Either your VB code has to pass the data, NOT necessarily as a String type, to the function in a format the function can deal with, like an array of Bytes that LOOKS like a string, or your function must be able to deal with BSTR's.

Does anybody have a work around for the problem, where you can't install VS SP5 when you have .NET installed. I installed VS6 OK but when I try to apply SP5 it says the setup did not complete. Doesn't seem to be much about this on MSDN, surprise, surprise!
Thanks all.

I installed VS6 after VS.NET2K3 and then SP5 for VS6 and didn't run into any problems... I didn't do anything special. I also don't use VS6 for anything other than answering questions here and for legacy applications that I don't feel like upgrading to .NET.

I tried installing from CD and downloading it. It seems to be a problem mentioned a few times on the WEB. I've had .NET installed for a while and VS6 went straight on. I tried to then open a project and it seems it needs a refeference to COMCT332.OCX from SP5, so I tried to install it. The SP5 setup starts after searching for installed components then shows the message that the installation did not complete successfully.
Any other offers?
I don't know what I could have done to make this setup not work.
Thanks

Hi,
I would like to use the FileSystemWatcher to run and external command if a file is renamed. For example, if a file is renamed to *.__old the file is copied to a new location.
So far I was able to make it work for 1 or 2 simultanious changes but there could be potentially 50 to 100 changes at the same time and it appears that there is a timeout waiting on the first command to execute.
Could someone tell me how I could get the FileWatcher to handle multiple commands at the same time?
Thanks....
|
|

Perhaps your event handler should start a new process for each change and use an asynchronous callback to let the FileSystemWatcher process know that it's done?

Howdy my friends!
I have been developing Pocket PC solution for SAP R/3. But, I faced a problem with web service on VB.NET 2003. My problem is, return parameters are set to "nothing", when I try to invoke web method from VB.NET. Actually, the SOAP response message recieves by client without a problem. I can see the response SOAP message by MS SOAP Trace tool. But Invoke method cannot parse it anyway. As a result i can't get any return value. What's lying behind of it?
My sample code as below;
' Set RFC parameters
Dim strPrm1 As String
Dim strPrm2 As String
' Set URL
Dim sURL As String
sURL = "http://ybpent:8000/sap/bc/soap/rfc?sap-client=274"
' Set credentials
Dim m_Credentials As ICredentials
m_Credentials = New NetworkCredential("xxxxx", "xxxxx")
' Set web service
Dim m_RfcClientInfoYBT As New dNETSOAP4SAPR3.RfcClientInfoYBT.RFC_CLIENT_INFOService
m_RfcClientInfoYBT.Url = sURL
m_RfcClientInfoYBT.Credentials = m_Credentials
' Call web service
m_RfcClientInfoYBT.RFC_CLIENT_INFO(strPrm1, strPrm2)
Proxy method as below;
'<remarks/>
<System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://www.sap.com/RFC_CLIENT_INFO", RequestNamespace:="urn:sap-com:document:sap:rfc:functions", ResponseNamespace:="urn:sap-com:document:sap:rfc:functions", Use:=System.Web.Services.Description.SoapBindingUse.Default, ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)> _
Public Function RFC_CLIENT_INFO(<System.Xml.Serialization.XmlElementAttribute(Form:=System.Xml.Schema.XmlSchemaForm.Unqualified)> ByRef HOSTNAME As String, <System.Xml.Serialization.XmlElementAttribute(Form:=System.Xml.Schema.XmlSchemaForm.Unqualified)> ByRef SYSID As String) As <System.Xml.Serialization.XmlElementAttribute("HOSTID", Form:=System.Xml.Schema.XmlSchemaForm.Unqualified)> String
Dim results() As Object = Me.Invoke("RFC_CLIENT_INFO", New Object(-1) {})
HOSTNAME = CType(results(1), String)
SYSID = CType(results(2), String)
Return CType(results(0), String)
End Function
Anybody has an idea about it?
Thanks.
