I am using VB 2005 and have connected to an Access database.
Rather than do the usual for i = 0 to total, can you populate an array with the dataset some how.
|
|
|
|
|
Do you want an array filled with the tables the DataSet contains? If so, and if you have included the System.Linq namespace, then you can use ds.Tables.ToArray(), where ds is your DataSet. The result of that method call will be the Tables property as an array
|
|
|
|
|
Or if you want to enter the values of a certain column from the dataset into the array you can use the For Each loop:
For Each rw As DataRow In YourDataSet.Table("WhatEverTable").Rows
Or considering that a dataset, in a sense, is a sophisticated array, you could consider forgetting about copying values to an array first, and just get them straight from the dataset.
My advice is free, and you may get what you paid for.

You can't possibly be the first one to ever want to do this. So, a little Google goes a long way, and I see that it's been documented about 40,000 times. Here, allow me... Click This[^].

Good luck with that.
First, you need to get VB.Net, as there is no support for VB6.
Second, No-one, and I really mean NO-ONE is going to do the code for you.
If you do not know how to even go about it, buy a beginners book and read it, slowly, twice, then when there is glimmering of understanding, attempt it yourself. When you fail, and you will, ask specific code questions about the portions of code you are failing on.
Thirdly, Never give your email address out, or you will suffer.
This constitutes a friendly reply, some here would really burn you for that.

"Some here"?? Noone here is going to burn him for it, but the spammer idiots out in the world will surely handle that themselves.

VB6 doesn't have any image handling capability that would work with the speed required to detect a face. You'd have to use an external C++ library to give you more speed.
Also, the fact that you're even asking this question says that you don't have the skill required to implement a face dectection algorithm yourself. This will be quite a large research project for you. Since you don't have the skill to do the research yourself, you don't have the skill required to implement the algorithm.
But, I'll give you a hint. Start Googling for "face detection algorithm". You'll notice that most of the URL's you get in the search results are for universities. What does that tell you about the technology?

I knew the task would be too much for him, it is a Massive Ask.
Certainly not something to be tried by anyone under the level of "Expert"

Ah, forgive me, an obvious cultural difference, for us Europeans, Asian names can sometimes be rather non-gender-specific.
I imagine it is sometimes true in reverse.
I would say it WAS possible, but still insanely difficult.
There is all the code for looking at images, then looking at specific areas of an image, then comparing data models for eyes, nose mouth etc, then ensuring they are in the relative positions to give then an overall facial matrix and then that they are not merely coincidental images that fall into the similar pattern to form a face.
(Note: Even the human brain does this when it sees faces in clouds or Marmite jars!)
Possible? Yes!
Easy? No!

And how would the fact that the OP owns a vagina change anything we have said ?

Since all versions of VB do not support pointers, getting that the image data without an external component is VERY slow. It could be done, just with horrible performance.

You're a moron. Know htat none of the spam you get from posting your address here, will be from the owners of CP. It will be from people who trawl the web for folks stupid enough to publically post their email. Apart from that, what the others said. VB6 is crap, and unsupported, this is a massive task, even in a real language, and it's clear on all fronts that you're too stupid for this task. Let your client know you're a liar.

Blimey Mate, don't sit on that fence will you!
Why don't you tell him how you really feel!
But yeah, Email Addys in a public forum? A gift!
As for what he wants? He best forget it!

I'm still trying to work out why someone thought you'd give them VB.NET code, AND felt that we needed to know that the OP is a girl. So what ?

That's rather a sexist remark, don't you think?? I work with two girls, one of whom holds a CISSP, who can kick my ass, technically.

Hi,
Iam using
Dim ConStr As String = "Data Source=1.1.1.1; initial Catalog=My_Databse; User Id=UserA; Password=xxxxxx"
dim con as new sqlconnection
con.connectionstring=ConStr
con.open()
But also I want to use the diffrent database called "Another_Database" with this same connection...
Is it possible?
|
|
|
|
|
You want to use two different database with the same connection?? AFAIK, that's not possible. But, I can see how I could very easily be wrong.
|

Fortunately for you Dave is wrong, if you remain on the same server.
Dim ConStr As String = "Data Source=1.1.1.1; initial Catalog=My_Databse; User Id=UserA; Password=xxxxxx"
dim con as new sqlconnection
con.connectionstring=ConStr
con.open()
'Do whatever you need to do in the first database here
'If there is a chance that some process will close the connection
'you also need to check for that first. The ChangeDatabase method
'requires an open connection
con.ChangeDatabase("Another_Database")
'Do whatever you need to do in the other database here
My advice is free, and you may get what you paid for.
