I've created a MAPI Wrapper in VB6 and compiled it as an ActiveX.exe so I can use it in my VB.NET project. The project is a windows service that takes data from a webservice passes data to activex.exe and it creates public folder records in exchange 2003. I was wondering if anyone know how I could pass a collection to my activex.exe?
View 1 RepliesI have a table that I need to insert a set of records into based on user input. IE: Selection from a list of items to choose from. For this example, let's just say it's a collection of int's.
Not a lot of good examples on the internet. There's only one related question here on SO, but it lends no answers either (both answers are dead ends).
How do you setup the call into the Package from .NET? How do you setup the Package Procedure or Function to receive the collection? How do you process the collection once inside of the Procedure or Function?
I'm not sure how to do this but I want to store data in several collections. I want the data to be stored / accessed as follows.
CombatCollection("Joe").CombatRecord(1).AttackRecord(1).Damage
how these nested structures or collections are defined and used?
I am trying to load an actixex component in a VB project which was made in Visual C++.n VBA it works fine.In VB6, when I try to load the component on the toolbox I get an "Error 35005"In VB2008 the component can be added to the toolbox, but when I try to place it on the form, the following error occurs: "Failed to import ActiveX control. Please ensure it is properly registered."

View 1 RepliesJust started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.

lets say I have:
arecord.name = "A"
arecord.value = 15 ' a number of type "long"
'
I then
call records.add(arecord,arecord.name)
' so far, so good but lets look at the next record
arecord.name = "B"
arecord.value = "this is text" as opposed to a number of type "long"
'can I then
call records.add(arecord,arecord.name)
ok this code will save data withc is URL from textbox and load it to listbox , but i want it save first name of uRl like google then in other textbox put URl and save so when its load data its shows only name like Google not [URL] in listbox sometimes the link is too long and it will be not good interface in form1 and then when u click Google in listbox it open its URl [URL]

So, I have a little issue.. I can't currently explain it using the software I'm developing because it's "internal"...

View 2 RepliesI am trying to solve an issue in my application where the following exception is occurring: there is already an open datareader associated with this command which must be closed first. I am using TableAdapters, which maintain their own DataReaders, and everything seems to work fine unless I am interacting with one of my background workers.
In my code, I shadow the Item property of my collections so that I can retrieve the actual data from the database if needed. Here is a sample:
[code]...
Now each reference to the Item get property instantiates its own DataAdapter, so I am confused as to how the same DataReader will ever be used in this scenario. Is there something I am missing? All the TableAdapters do in fact use the same connection object, but I wouldn't think that would be a problem
I have these objects:[code]Using LINQ I need to take a List(Of MakeInfo) and a List(Of ModelInfo) and aggregate the StockInfo from ModelInfo into the List(Of MakeInfo).So for each MakeInfo I will have a total count of all stock where MakeInfo.Name = ModelInfo.Make, and also a minimum price.I think it's going to be something like this, but I'm having trouble accessing the nested object and not sure if it's going to be possible with a single query.[code]
