This is silly, but i want to know where the best place is to make a script file for the creation of a new database. Must i write the script file in VB.net or in Access? And how do i use it (implement the script file so that a new database is created)?

Please help, I am in the dark!

Yes MSAccess, and I want to use it for adding an extra company's database to my program.

OK, I can copy the existing db, but i don't know exactly how many companies will be added!

I am doing it in VBScript now, but still don't know how to use it!

readprocessmemory to read contents of specific (other process) memory address.

I have been searching for days, but I just can't seem to make heads or tails of anything google brings up. Here's my situation, I need a quick and dirty program that can read the contents (string) of a specific memory address of a separately running process.

I have it to the point where I can find the window I need via hwnd/findwindow, I can associate the processID, but everytime I dive into readprocessmemory I just can't make it work. Any help is greatly appreciated. Thanks!

PS - VB6, not VB.net

The first thing you have to to is make sure that the process handle you get (NOT the same as the processID!) has PROCESS_VM_READ rights. You can do that with a call to GetSecurityInfo.

The docs for GetSecurityInfo are here:

Internet Transfer Control

I am currently working with the internet transfer control in VB6, but I have a problem. The file I need to get is passworded, but it's not an FTP site, and I know the control has ways of doing usernames and passwords on FTP's, but this is just a regular page with an account name and password.

Right here's where I need to get it from: https://www.e-gold.com/acct/historycsv.asp

But as you can see, username and password are needed. I haven't the slightest clue as to how to get the username and password in there and push it through to get the file I need. I know it's possible on this site, it's been done before by a programmer with about the same skill as me. But, he doesn't want to share code Poke tongue | ;-P

Any help?

OKay, I randomly just figured that out on my own. New problem::: The values in the file are comma seperated. How to I parse it? (there are some strings of commas that have no values or spaces in-between too, FYI)

Hi there,
i found a really good article about multithread tcp handling, but i code in VB.NET and the source is in c#; i managed to translate most of the code, but some of them are out of my knowledge, please help

##################
private Thread [] ThreadTask = new Thread[NUM_OF_THREAD] ;
ThreadTask[i] = new Thread( new ThreadStart(this.Process) );
ThreadTask[i].Start() ;
//NUM_OF_THREAD is a const
##################
public ClientService(ClientConnectionPool ConnectionPool) {
this .ConnectionPool = ConnectionPool ;
}
//is this a function ? a sub ? how do i translate 'this' ?
##################
lock( ConnectionPool.SyncRoot ) {
if ( ConnectionPool.Count > 0 )
client = ConnectionPool.Dequeue() ;
}
// lock opens {} as an if ?
#################

Thanks in advance

the first bit declares an array of ThreadTasks containing NUM_OF_THREAD items, and then initialises and starts the i^th member

this in C# is Me in VB

lock declares a critical section. I'm not sure what the VB equivalent is

Thanks,'me' worked perfectly
I understood what
private Thread [] ThreadTask = new Thread[NUM_OF_THREAD]
say, the matter is that i cannot find a way to rewrite it in vb
the only near declaration accepted from the syntax that i found is
Private ThreadTask as Thread(NUM_OF_THREAD)
but i miss the 'new' part. Any idea ?

Thanks again for the kind help

Well, I'd just declare the array as you would any VB array, and try it like that.

OpenRecordset bollocks

Dangleberry14-Sep-03 23:19

Yo all, have entered a stupid problem which I'm not sure is a bug in VB. I have this code:

<br />
Dim Record as Recordset, DB as Database<br />
Set DB = OpenDatabase("c:\db.mdb")<br />
Set Record = DB.OpenRecordset("BASE")<br />

Yet this remarkably simple code falls over when setting the recordset, because there is a "data type mismatch" (groan), when in fact there is no data type mismatch. OpenRecordset returns, guess what, a recordset, so wtf????? To add insult to my injuries, if I declare Record as a Variant instead, the line proceeds and guess what, Record gets cast to a, wait for it, Recordset object (ie. I can access the variant as I would a recordset and in debug the fields are identical), and all the data is intact and correct. Also, interestingly (though wankily) if I cast the Recordset object to a variant using CVar and then call OpenRecordset, I get no errors and indeed no recordset object, its just set to 'Nothing'. Is this just another episode of why VB is so sh*t? Can someone explain to me how a function returning a Recordset object can have a data type mismatch when trying to assign to a Recordset object??? Honestly, this is basic programming logic which this stupid, shitting language cannot grasp. I await someone to prove me wrong.

Dangleberry15-Sep-03 0:19

OK guys, found the answer elsewhere on the web, and guess what, its sh*t. Basically VB defines two recordset objects, both called 'Recordset', for ADODB and DAO, which is fair enough. However, fatally, VB CANNOT differeniate between the two, so whenever you specify Dim Record as Recordset it always assumes you are using the ADODB recordset object, hence the data type mismatch because OpenRecordset returns a DAO recordset, duh. This is exactly why VB is sh*t. C++ adopts a technique of namespaces, if there is ambiguity in the type the compiler will throw an error saying 'use of ambiguous types', nice, addresses you to the problem. VB just kicks up some bullshit AT RUN-TIME, which is horrible, horrible, horrible, because no end of bugs could manifest themselves. You even have to specify Option Explicit to force the compiler to point out basic compiler errors such as undeclared identifiers. This is wank. Anyway, the solution is declare the recordset as part of the DAO 'namespace' like so Dim Record as DAO.Recordset.

VB should be burned on a cross and sent to hell for its sins

Yeah, I know exactly what you mean. It just totally disgusts me how flimsy the compiler is, and annoying when have a line myvar = and then press enter and it comes up with a box saying you did something wrong, when really you were just gonna cut and paste some code. I only use VB when absolutely necessary, like when I have to knock up some bullshit app in a day or so. Its strange mind, cos this guy at work, Mark, he loves VB, personally I think he must be a bit sadistical to love VB.

Lots of Love Simonxxxxx.
