VBA/Excel - Charting question

Jon G10-Jun-04 5:10

(REVISED)

I am trying to do the following:

-Check each Point of a chart series to ensure it is within specific limits
-If Point is not in limit, change the Marker type of that Point

What my question is, how do you check specific Points in a series using VBA?

---------------------------------

After posting this question, I found out how to check the point values. I still cannot figure out how to change these individual Marker types to what I want.

Here is the code to check the values:

'***Checks series points, and colors them if need be<br />
Function RefreshPoints(ChartName)<br />
    <br />
    Dim nPts As Integer<br />
    Dim aVals As Variant<br />
    <br />
    Worksheets(ChartName).ChartObjects(1).Activate<br />
<br />
    With ActiveChart.SeriesCollection(1)<br />
        nPts = .Points.Count<br />
        aVals = .Values<br />
        For iPts = 1 To nPts<br />
            MsgBox aVals(iPts)<br />
        Next iPts<br />
    End With<br />
<br />
End Function

Can anyone tell me how to build on that above function to change the marker type of a single Point?

For those who care, I have solved my problem.. here is the final code:

'***Checks series points, and colors them if need be<br />
Function RefreshPoints(ChartName)<br />
    <br />
    Dim nPts As Integer<br />
    Dim aVals As Variant<br />
    <br />
    Worksheets(ChartName).ChartObjects(1).Activate<br />
<br />
    With ActiveChart.SeriesCollection(1)<br />
        nPts = .Points.Count<br />
        aVals = .Values<br />
        For iPts = 1 To nPts<br />
            .Points(iPts).MarkerBackgroundColorIndex = 35<br />
            .Points(iPts).MarkerForegroundColorIndex = 1<br />
            .Points(iPts).MarkerStyle = xlTriangle<br />
            .Points(iPts).MarkerSize = 13<br />
            .Points(iPts).Shadow = False<br />
        Next iPts<br />
    End With<br />
<br />
End Function

Now its just missing a few If statements to finish up, but thats what got it working. Just thought I'd post the code if anyone was interested.

sqldataadapter?

When I use this code:
Dim pubsadapter As sqldataadapter = New sqldataadapter("select*from authors", pubssqlconn)

And Build It. the results gives me that sqldataadapter not defined.
I Imports the following before:
Imports System.Data
Imports System.Data.SqlClient
Thanks

Go forward and never Stop....

Re: sqldataadapter?

Dave Kreskowiak10-Jun-04 4:11

Then it should work. The lowercase spelling of the SqlDataAdapter name tells me that the Imports statements are incorrect somehow. They are spelled correctly, but possible not at the very top of the code file? They should normally come before any Namespace or Class statements.

You might want to try posting the code so we can see it?

Does it give any error at 'Imports' statement. VS.NET includes reference to System.Data.dll in most of the project templates. If we remove this reference to System.Data.dll, Imports will have no meaning. Imports is just to import the namespaces just for coding purpose but we still have to have a reference in the project.

TreeView --> Move Nodes

Hi.

Can anybody tell me if there is a way to move nodes within a TreeView? I have found how to use drag-and-drop between two different TreeViews but haven’t been able to figure out how to tweak the code to make it work within ONE TreeView.

I would like to be able to simply move child nodes (and parent, if possible) up and down in the Tree.

Thanks

It's our first semester here in our school and part of our 4th year standing here is to create our own information system. Can you suggest some systems except enrolment systems, election systems, point-of-sale systems, accounting systems, etc...

Thanks...

byte length restriction in text box

Rohitse9-Jun-04 22:14

Rohitse

9-Jun-04 22:14

Hey All,

I have a simple quetion to ask.
The maxlength property of an edit box restricts user to enter more than the specified characters. But in the Japanese system, if user enters double-byte characters, then the actual byte would exceed that limit.
Do we have similar restriction on byte length as well?
I used LenB() method but it considers even the Ascii characters in the English language to be 2 bytes long.
e.g LenB("123") gives me 6.

So is there any generic function which would return me the exact bytes in a string (considering the 1 byte and 2 byte characters differently) and that can be used with English system and Japanese systems where user can enter Japanese as well as English character in the text box.

Thanks
Rohit

RichardGrimmer9-Jun-04 23:17

VB (6 at least - not sure about .NET) uses BSTRs to handle strings, which are always two bytes / char (AKAIK), with a couple at the front end for length...

All Strings in the .NET Framework are Unicode strings. They all have double-byte characters, so yes, "123" will return 6 bytes.

You can't have two different encodings in the same string. It's either going to be all single-byte, or all double-byte, not both...

Scheduler sample code

9-Jun-04 22:01

I'm developing a simple scheduler application for my company in VB.NET (Windows Forms).

(No, I can't use a standard product due to reasons I can't go into here)

Anybody have any sample code or simple framework which can help me getting started so I don't have to start from scratch ?

I'm looking for some simple code which shows how to make different schedules (every hour/day/week/month/date, on fixed times/dates, etc)
I of course know how to make timers, services, execute stuff, UI, and the rest of the application - only need help for the shedule checking part.
Maybe some kind of simple class library...

TIA Smile | :)

Custom Draw TabControl

beowulfagate9-Jun-04 20:47

9-Jun-04 20:47

Ever seen the tab control on Windows messenger? I know that it is actually a web page but I got the idea of somehow turning it into a windows forms control. However, I got into a snag custom drawing the tabcontrol. I can't seem to resize it so that it has space to display an icon instead of text nor can I custom draw the tab itself, just the same old boring rectangle - not the cool, new curved tabs like messenger. Any ideas?

Create application shortcut

Hi Is there a function that let me create a shortcut to an app?

Thanks

Re: Create application shortcut

Dave Kreskowiak10-Jun-04 3:42

Dave Kreskowiak

10-Jun-04 3:42

There is no function in the .NET BCL that will handle this. You will have to use the Microsoft Scripting Runtime (set a COM reference to this!), create a Windows Scripting Shell object and use it to create the shortcut. Something like this (I think!):

Dim WshShell As New WScript.Shell
Dim oShellLink As WScript.Shortcut = WshShell.CreateShortcut(strDesktopPath & "\Shortcut Script.lnk")
oShellLink.TargetPath = WScript.ScriptFullName
oShellLink.WindowStyle = 1
oShellLink.Hotkey = "CTRL+SHIFT+F"
oShellLink.IconLocation = "notepad.exe, 0"
oShellLink.Description = "Shortcut Script"
oShellLink.WorkingDirectory = strDesktop
oShellLink.Save

I haven't tested this code, but it should look SOMETHING like this. I don't have Visual Studio where I'm at work, so I would have to wait until I got home to create a runnable example.

See if you can consider creating shortcut at the time of deployment wherever you need using Setup projects. I suppose, this would be the best .NET solution.

You'd have to associate your application with windows as being able to handle that particular file type. You'd have to be able to get the ProgID of your application then add that ProgID to the registry.

Your App's ProgID
HKEY_CLASSES_ROOT\Your_App
Default=Your App Name
\curver
Default=Your_Company.Your_App.Version
friendlyname=@Your_App
\shell\open\Command
Default=%Path to your App%\Your_App.exe %1

Then place something like this into

HKEY_CLASSES_ROOT\*.Your_App_File_Type
Default=Your_Company.Your_App.Version

Or if you want to handle folder types, look for the '*' filetype. If your really curious, you can find the Winzip registry entries there too.

Phew!!! There must be an easier way!!! If you find it, find me!!!
