Well I have to edit an exsisting program that was written in vb6. One of the things that I am doing is adding mysql support to the program, which is in vb. There is no vb api for mysql so I had to write some dlls in c++ to handle mysql for the program. My problem now is that the program cannot find the dlls. Although they are in the same folder, and im sure I am calling them properly. Here is how im calling a function from one of my dlls in vb:
Declare Function writeInfo Lib "RideMySql.dll" (ByRef Param1 As String, ByVal Param2 As Integer, ByVal Param3 As Double, ByVal Param4 As Double, ByRef Param5 As String) As Integer
The corresponding funcion in c++ is prototyped as:
int __declspec(dllexport) CALLBACK writeInfo(char* param1, int param2, double param3, double param4, char* param5);
Thanks in advance.

Have you included a .def file within the C++ project? This allows VB to talk to the C++ .dll.

thanks!

Hi
I am also trying to build a messenger in VB.NET. Yes its possible using Winsock. But i am somehow unable to incorporate winsock API in my vb.net application.

Hi there!
I am learning VB.net, and want to develop my own text editor for program code.
How would I colour certain key words only??
If someone could point me in the right direction I would be most grateful!
Many thanks in advance,
Dan Fowler

You could easily catch evt the KeyUp event and see if theres somthing typed in that should be colorised..the keywords you could have in an array or something.. simply look up if theres is a match in the array, and then set the color.
Hmm...
|
|
|
|
|
You also need to be able to manage things like cut/copy/paste and the crazy way the poeple can edit (moving cursor around).
All in all it is not really easy, and an clear, fast, easy methid is not trivial.

What's the function to get the local computer name in VB6?
Have a good one!
|
|
|
|

There is none, but you can import GetComputerName from the windows API
|
|
|
|
|
You will need this in a module:
Declare Function GetComputerName Lib "kernel32.dll" Alias "GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Then in your code:
Dim compname As String, retval As Long
compname = Space(255)
retval = GetComputerName(compname, 255)
compname = Left(compname, InStr(compname, vbNullChar) - 1)

I have a code which is less complex
you will have to import import system.net.dns
Sample code is as follows:
Imports System.Net.Dns
Dim shostname As String
shostname = system.Net.DNS.GetHostName()
console.writeline("Your Machine Name = " & shostname)
hope that helps

I have a data entry entry screen. Here users are entering Checks details in batches. Each batch is having about 200 checks. User wants to save each row after finishing the row.
I did by using XMLDom. Which is calling another page? It is perfectly submitting the values to the database?
But it is slow and putting lot of load on the front end and increasing heavy network traffic in a 50 people environment.
Is there any better way to Insert, Update, delete the rows.
I am using asp, Oracle with IE 6.0

By saying Front end , do you mean that browser? If so, make sure that the asp page doing database update is returning only S(uccess)/F(ailure) message and then updating the DOM? If that is the case, it shouldn't put any load on front end because the page does not get refreshed.
Web-server load (so with N/W load unless it demands upgrade) is ok for 50 users because 50 users can not be 50 concurrent connections, in web environment.

Greetings all!
I am new to programming .NET and, to be perfectly honest, I'm not really an experienced programmer. I'm an engineer that is going to have to be doing some development. So, I'm looking for the best resources available for learning/developing in .NET. Where do you go for on-line information, add-ons... those things that make development time easier? I've been hearing about "communities". Do you really use those and are they valuable, or do you spend more time in discussion forums like this? What are the best forums?
Any information would be valuable. I appreciate your time!

You have opened the recordset as a "forward only" cursor.. change it and i think it will work just fine.
Hmm...
|
|
|
|
|
You are using a Command obj that is returning an recordset.. ??
Set myRS = myCmd.Execute()
If true, then how is this Query definede..?? Which db are you using.. evt try using clientside cursors
Hmm...

If you can not pay: Either use TAPI or MS Communication control (with VB - check MSDN)
If you can pay, there are several APIs such as HAPI (check hyperterminal in your system).
