2D Xy Graph In Visual Basic


I am facing a problem in drawing a 2D XY graph . Acutally I developed a software for heat exchangers and now I like to view the profiles of my calculations. So to say a 2d xy graph.

In my program, I am calculating Temperature via length but both of these parameters are determined in a sub routine.

Now I like to make a two dimensional array consisting of length and temperature values i.e

Length( 0. 1 to length1) ' length1 is calculated as a function.
Temperature ( 30 to T1) ' T1 also calculated as a function.

So in order to get values in length1 and T1, I should first call their sub routines.

Now, how to make array with functions(i.e Length1 and T1) in it, and to assign values to the MSChart.Chartdata.

Visual Basic Items Removed From Visual Basic.NET
A while ago (maybe up to a year) I had found a web page (probably a Microsoft MVP's home age) that had a list of about 100 things that were removed from Visual Basic in the transition to Visual Basic.NET. As it is, I would like to look at that again, but I can't seem to find it on my computer. Does anyone remember this page and/or have a copy of the link or the file that was on it. It has particular things like Debug.Print is no longer valid and MsgBox function is not supported. I've look on Microsoft's website and found a great deal of information about implementation difference, but I can't seem to locate this particular piece. If anyone could help I would appreciate it very much.

Thanks in Advnance

What Are Advantages Of Visual Basic .net Over Visual Basic 6.0?
I am thinking of installing Visual (standard version) in place of Visual Basic 6.0. I dont know what are the disadvantages of it and I am hesitating to do that. I thought that I should ask the forum before making this decisions.

Would someone help me to know the followings.
1. If I install, and if I do programming in, will I be able to run it in Visual Basic 6.0?

2. Can I do everything that I do in Visual Basic 6 in Visual Basic .net?

3. Are there things that I can do in Visual Basic . net which can not be done in Visual Basic 6.0?

4. Would you recommend Visual in place of Visual Basic 6.0?

Thanks in advance.

Basic Question About Excel Macros And Visual Basic
I have a macro in Excel that takes some input on data ranges and produces charts based on the input. I want to place those charts (a number of them are generated) at a certain point in my excel worksheet. I know I can nudge it over by a certain amount but I can never tell where Excel will place them so I would like to just say "hey chart, sit here". Being able to do that in relation to cells would be great. Also, I would like to know if there is any way to resize the chart without using the percent. Once again, in realtion to cells would be great. Thanks for your help.

Visual Basic Development &amp; The Visual C++ Shared Objects
I having a really irritating problem. I'm developing an Add-in in Visual Basic... however, to do the development I'm doing, I require the "Visual C++ shared Objects" reference to be added to the project.

Here in lies the problem. I also need the VB command left [as in left string copy - ie. left("aaaaa", 2)] The only problem is that by adding the "Visual C++ shared Objects" reference, the LEFT command is overridden with the C++ version which returns a long (or something like that).

In the References window, I've already set "Visual C++ shared Objects" to the lowest possible priority... is there anyway to get around this arrangement?

Thanks in advance,

How To Access Visual FoxPro Data In Visual Basic

adott1.ConnectionString = povezava
adott2.ConnectionString = povezava

adott2.RecordSource = "SELECT sifra,grupa,naziv,nabavna,vpc " _
& "FROM izdelki "

to view data in datagrid

I delete a record :

Record is marked in FoxPro as deleted ( not yet PACK ) but in Visual Basic datagrid (adott2.refersh ) record is still in it.

How can i execute PACK in Visual Basic????

Dumb Question About Visual Basic / Visual Studio...
From someone who has been programming as long as I have, this has got to be a dumb (DUH!!!) question.  But if I don't get it answered, I'm going to continue to run around in circles.  The problem stems from what appears to be a simple name change, and the fact that I only upgrade my software infrastructure here every few years, so I miss what's going on.

VB6 appears to be the last (terminating) version of Visual Basic.  There will be no VB7.  But, clearly, the language itself is not being terminated -- just called something else, or is being "assimilated" (resistance is futile) or absorbed into a larger platform, losing its identity as a stand-alone programming environment.

How does Visual Studio relate to Visual Basic?  Is the "next generation" version of Visual Basic now being called Visual Basic.NET?  Is VB.NET part of Visual Studio?  If I get Visual Studio, is VB.NET automatically part of that package?  Or is Visual Studio one thing, and VB.NET something else entirely, ordered as two separate things?  If I want to keep programming in VB (as a programming language/environment), do I now have to get Visual Studio instead?

Sorry to bother the more enlightened souls here with a DUH question -- but I gotta ask SOMEBODY...

Thanks.  You folks have been a GREAT help here.

Visual Basic Versus Visual C Performance
Hi people :

A question that many of us make to ourselves. Ive not received a convinced answer.

Ive heard already thousand times that programs writen in C run "better" and "faster" than programs written in Basic. The same for Visual C against Visual Basic.
Even Visual C has better press than Visual Basic, I mean, a commercial software written in C seems to be "stronger" than a commercial program written in Visual Basic.
I understand that programs can be well written or not so well, no matter which language is used, but Im talking of well written programs, in both languages.

But, what is the truth behind all this.
Suppose a program that works in a network.
The program will use the winsock that comes with Windows, no matter if the program was written in Visual C, Visual Basic or whatever language the programer is using.
Lets supposed that that asumption is true, that means that the Visual Basic program does things in a slower way than the one in Visual C, so, the Visual Basic compiler is charging our code with processor instructions to do nothing.

Im not a Visual C programer. I think that I write optimized code in Visual Basic.

I will appreciate comments.

Visual Basic/Visual Sourcesafe Problem
Having a problem at work with sourcesafe and vb 6. I have one computer here that for some reason after using SourceSafe to grab the newest version of code from the server and copying it to the local machine, it prompts with a save as dialog box when trying to save (want it to save to the local machine, will update sourcesafe copy later).

Any ideas? I have the following from MS, but this happens only on one machine and we don't use ActiveX Controls

Combining Visual Basic And Visual C++ Code
I need to embed C++ code in my Visual Basic project without using a DLL.
I understand it's something to do with the linking process and it is described here:

Visual Basic 6 &amp; Visual Styles: The Story
Ok... I've got Windows XP... great OS... I've got XP SKins... great Program... and I've got Visual Basic 6... great IDE... so I thinked... what about giving my applications Visual Styles Support?

So I did it, I've added Visual Styles to VB 6 and to my application and... IT WORKED!!! I had the cool XP Buttons and Checkboxes... GREAT!!! I tried Tabs too!!! They worked... frames worked too!!! But after two days my application started to play the Critical Error sound...

I tried to do another application with simpler things... and after a lot of experiments I've discovered that with standard controls (Buttons, Option Buttons, Check Boxes...) the application doesn't work and with other ones... it works! I tried everything from upgrading to using UxTheme.dll... So now I just talk about it with other people... hoping to find someone able to explain me WHY does my application worked once

Thanks for reading the whole thing

Some Really Basic Visual Basic Questions
Hey all,

...I'm stressing the really here. Reading through some of these topics, it looks like you guys are all really advanced in this program.

I, on the other hand, am a complete VB newbie who needs to hand in a stupid project for calculus class tomorrow.

Long story short, we need to create a basic job application, about five or six forms long.

I have no idea how to code the buttons that I'm using. I need to make one command button send the user to the next form, and I need to make another exit out of the project entirely.

How would I go about doing this?


Very Basic Visual Basic Problem
Hi, it's basic alright, and it's driving me mad.
I was given the disk by a friend who has moved abroad and I can't contact her.
I am very keen to learn how to use it and currently know nothing, well almost.

So I have been on a tutorial website and produced and calculator,which I am proud of though I don't yet know how to make it calculate.

Instructions on website....."If you are satisfied with the appearance, go ahead to save the project. At the same time, you should also save the file that contains your form.

so I save the project named calculator, and cannot see how to save "form"

when I check folder where it was saved there is a form file and a project file saved.

when i try to open it again to do more work a message box pops up stating that file could not be loaded - giving no reason.
The options open to me are "ok" and "help"
if I click help a message box tells me that "the MSDN collection does not exist. Please reinstall MSDN".
I have tried to do this but my computer cannot find it on the disk.
If I click on "ok" the box disappears and I am no further forward.

I am sure that I must be making a very basic mistake.

Version in use is VB6 Pro. clearly not safe in my hands.

any very simple clear advice to a complete novice would be greatly appreciated.

thankyou very much


Power Basic VS Visual Basic
Anyone here uses Power Basic?
Is it any better than Visual Basic?

Power Basic can produce EXEs with no runtime dlls.
Power Basic provides 30+ standard controls.

It is said to produce extremely fast-running EXEs.

Any thoughts?
