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.

I was trying to write data in the event log. I found these lines of code somewhere:
Dim bRC As Boolean
Dim iNumStrings As Integer
Dim hEventLog As Long
Dim hMsgs As Long
Dim cbStringSize As Long
Dim iEventID As Integer
Dim sMessage As String
Dim sSource As String
sSource = "ErrLog"
sMessage = "Success Message"
hEventLog = RegisterEventSource("", sSource)
cbStringSize = Len(sMessage) + 1
hMsgs = GlobalAlloc(&H40, cbStringSize)
CopyMemory ByVal hMsgs, ByVal sMessage, cbStringSize
iNumStrings = 1
If ReportEvent(hEventLog, _
EVENTLOG_SUCCESS, 0, _
EBALOG_SUCCESS, 0&, _
iNumStrings, cbStringSize, _
hMsgs, hMsgs) = 0 Then
MsgBox "FAILED"
Else
'-- Sucessful
MsgBox "Success"
End If
Call GlobalFree(hMsgs)
DeregisterEventSource (hEventLog)
But it doesn't work, The function always returns 0. And it doesn't write anything on the log.
please help.

The return value is zero because there was a failure. Use GetLastError to get the error number, then look that up here[^]. This is the System Error Codes list on MSDN.
You might want to check the value returned by RegisterEventSource first. It looks like your not getting a good EventLog handle returned here. Your passing in an empty string instead of a 0 (which means NULL). This is where I think your problem is. If you change the call to this, it might work:
hEventLog = RegisterEventSource("." & chr$(0), sSource)
Again, if you get back a zero for either RegisterEventSource or ReportEvent, then use GetLastError to find out what the error was.

hi,,,
I want to pass a value in a formula field in my report(Crystal Report 9) through Front-End. I am using CrystalReportViewer. Like in Vb 6.0 we used to write
CrystalReport1.formulafields.item("formulaname").text = FormulaValue
How to do this using vb.net and Crystalreportviewer???
thx

Something quite similar:
Dim rd As New ReportDocument
rd.Load("c:\MyReport.rpt")
rd.DataDefinition.FormulaFields.Item("FieldName").Text = "..."
crv.ReportSource = rd

Thanks for your reply, But I am not using any Report Document. I have Crystal Report Viwer object on a form, and i am passing the reportsource through another form. My code is as below.
Dim frm As New frm_reportviewer() ''' form which contains crviewer
frm.CrViewer.ReportSource = Application.StartupPath & "\reports\rep_EFileStatusReport.rpt"
frm.Show()
What is the property of CrViewer to pass FormulaFields??? I am not getting it?
thanks

With a little research, it looks like your going to have to use a ReportDocument in order to do what you want. You create a ReportDocument using the code in the previous post, then pass the document to the CrystalReportViewer.ReportSource property so it can be viewed.
Read the example given a little closer and you'll find your solution.

Yeah, what Dave said. You're not using the ReportDocument object, but you need to in order to access the FormulaFields collection.

:-DI've seen code using c# to input/output using whether serial or I/O card. But still I can't find any of it in VB especially in VB 6. Can you guys give me any tutorials or websites or maybe an example by using VB 6

I've used this[^] library before. It's pretty good and gives you all the control you want.

First, sorry for reposting this again (previous post)[^], however I have had not much luck researching this one, so I just want to ask for tips/hints on this matter.
The problem:
I need to set the stapling capability of a printer before printing a document (in a Word global template, i.e. VBA code).
I have found an API to set printer duplexing, which unfortunately does not include setting the stapling.
I've had a look at PDL (Page Description Language) but I find that it will be too complex to put the PDL command on top of the document file before printing it out.
If anyone has ever done this before can you please inform me on how to set printer stapling?
Thanks,
Edbert P.

I can't find a single code example (in any language) that even comes close to what you want. The only example I could find is buried inside driver code, which won't help you because your not doing the actual job assembly and printing.
There are a couple of problems:
1. You need to set the stapling in PageSetup of the document before it is printed. This will not be accomplished using the API calls. What you've been looking at is setting the default for the printer for ALL documents being printed by ALL applications.
2. Since not all printers support stapling and the ones that do require you to send different data structures to enable stapling, coding this is going to be a GIANT pain.
If your doing this as a document template, you should be able to start a document, using the printer with stapling as the default printer, go into PageSetup and set everything you need to, including stapling, then setup your documents properties the way you want, then just save the template as a .DOT file. When you create a document using that template, stapling SHOULD be enabled, and not if the printer doesn't support it.
The above has NOT been tested since I don't have access to ANY printers that support stapling (rare, but cool, beasts that they are.)

Has anyone seen controls/code that produces the sort of functionality provided by the "To:" text box on an Email message? In other words - clicking a button brings up a list of items to select from, one or more items are selected and appear in the text box, double-clicking one takes you back to the relevant item in whatever data source you're using, but after an event (send or whatever) the relevant data is then copied elsewhere (to the Email item or elsewhere).
