I create a DLL in VC++, call VD.DLL, and include file VD.CPP, its contain:
int _stdcall VD(int *index)
{
int i;
for(i=0;i<5;i++)
index[i] = i;
return (i);
}
In VB6.0, i declare to use this DLL:
Private Declare Function VD "my-dll-path" (ByRef intIndex as integer) as Integer
And use this function in VB's body like this:
Dim intIndex(0 to 50) as Integer //Global Integer Array
Sub VD()
Dim i as integer, intI as Integer
intI = VD(intIndex)
for i=0 to intI-1
MsgBox "Value " & i & " = " & intIndex(i)
Next
End Sub
And It shows :
Value 0 = 0
Value 1 = 0 'Unexpectly
Value 2 = 1
Value 3 = 0 'Unexpectly
Value 4 = 2
The second and fourth line is not correct. Because in my case, i must show:
Value 0 = 0
Value 1 = 1
Value 2 = 1
Value 3 = 3
Value 4 = 4
Why this happen? Anything wrong in my code?
Thanks

Yep. the int type in C++ is a processor specific widht integer, usually 32-bits. The Integer type in VB6 is a 16-bit integer. In your VB6 app, change your Integer types to Long (32-bit signed integer in VB6) and it should work.

I am looking for a SQLHelper class for an access vba application. I am in a time crunch on a project and would like to find an exsisting piece to start working from.

I started programming VB with the Learners addition 6.0. It did not come with several of the more advanced components, especially MAPI. Instead of move to the VB6 Professional, I purchased VS.Net 2003. Now I am really lost.
I am trying to create an application that will create an email using the default mail client and I am going to pass some variables to, like message text and an attachment. I do not see that MAPi came with VS.net. I see system.web.mail, but that does nto appear to use the mail client on the local machine.
Is MAPI part of VB.net? Is there a way to do what I describe without owning the MAPI OCX from VB6?

MAPI doesn't come with any version of VB. The Messaging API (MAPI32.dll)is only installed with Exchange Server, Exchange Client, the full version of Outlook (not Express!), or Windows Messaging.
The System.Web.Mail namespace in the .NET Framework wraps the CDOSYS (Collaboration Data Objects for Windows 2000) and will either send mail using the SMTP mail service built into Windows 2000 and above, or use an arbitrary SMTP server. CDOSYS is a COM component that wraps the CDO API 2.0, NOT MAPI. Lost yet? Read this[^].
Now, in order to launch the default STMP client (not MAPI!), you would do the same thing that IE does. Shell the command line:
mailto:someone@somewhere.com?subject=Some subject?body=Some message body
But, attachments are not supported this way!

Possibly using a process?
|
|
|
|

You can do that with Crystal Report.
That´s a VB component to print.
Very easy to use.
|
|
|
|
|
How to do that? Do you have any document or resource on the web to demonstrate about this technique?

You can see this page: http://www.businessobjects.com/products/reporting/crystalreports/appdev.asp .
But it is really easy. In VB you have to add the Crystal Report Component; in VB.NET it is named ReportDocument.
The file you want to print has to be a crystal report document (you can download the software in the site above). Then you have just to work with properties and methods.
Ex in VB.NET: reportDocument1.PrintOptions.PrinterName = ""

File path to what kind of document? There printer object cannot interpret every kind of document. Actually, it can't interpret ANY kind of document. What you do depends entirely on what you're trying to print.

Hey thanks for the feedback.
I have an installed PDF printer that i want to send my documents (MS Office Documents) too and also a 'print' command. The printer will do the rest.
Does this make it harder or easier to print the files or is the situation still the same?
Thanks
Chris

That's better. Word will actually have to do the printing. The PDF printer will just render into a .PDF what Word outputs when it prints. If you're just going to convert Word documents, you can use the Word (Office) automation model to load the document, select the printer, then print the document. It's been covered dozens of times in the forum, just search for Word using the "Search comments" link.

Sir,
I've a Windows Services on application server that listen to the folder files & process it.
In turn, the data will be inserted into a table in SQL2K and the associated trigger will call the stored procedure that will call the exec master..xp_cmdshell to call ASP page that generating a report (image).
This scenario works well when the application server in log on status..
but while the server is log off..
the errors below appears:
1)
System.Data.SqlClient.SqlException: A severe error occurred on the current command. The results,
if any, should be discarded.
xpsql.cpp: Error 997 from GetProxyAccount on line 604
2)
A severe error occurred on the current command. The results, if any, should be discarded.
at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream)
at System.Data.SqlClient.SqlCommand.ExecuteReader()
thanks...
Best Regards,
Sayhigh Soon
