Something like this should do the trick
public Form1()
{
InitializeComponent();
list = new List<TestGridImage>();
AddToGrid(0, 2);
AddToGrid(1, 0);
AddToGrid(2, 1);
}
private void AddToGrid(int index, in alt)
{
TestGridImage image = new TestGridImage();
image.KeyIndex = index;
image.KeyIndexAlt = alt;
list.Add(image);
}

.NET 2 didn't understand that syntax for new object creation: you either need to use a constructor (if one exists) or set the property after it is created:
list = new List<TestGridImage>();
TestGridImage t;
t = new TestGridImage();
t.KeyIndex = 0;
t.KeyIndexAlt = 2;
list.Add(t);
t = new TestGridImage();
t.KeyIndex = 1;
t.KeyIndexAlt = 0;
list.Add(t);
t = new TestGridImage();
t.KeyIndex = 2;
t.KeyIndexAlt = 1;
list.Add(t);

The firstly thank you for just help me, I also encountered one more issue, which is the order of List<...> column. when I assign this.gridControl1.DataSource = list; list column order does not appear like that, I want to change the order of the column list what I have to edit ?

I have built a class library using VS 2013 C#. It includes an interface to expose all the functions and public properties. It compiles and registers for use as COM visible. I can readily access the functions in the library from VBA. But there seems to be no way to access public properties in the class library with VBA. All the information I find on the web is for simple applications where there are no public properties, only functions. My efforts suggest that accessing public properties in the library is not doable. Is my conclusion correct? If there is a way to achieve it, maybe someone can point me to a resource.

Might not be quite what you're after, but couldn't you expose the properties by means of (explicit) getter and setter functions?

Thanks, Peter. I was hoping to avoid having to add/modify the classes that are built for .Net use with methods and properties. But I have not found any other way to approach it other than the one you suggested. On another tack, is there any software to generate an interface from the methods and properties in a class? I use copy/paste/edit which is time consuming. But I do have lots of time. Microsoft has made it difficult to use .Net with VBA, going in either direction. And it's maddening to try to hook to an open Excel workbook from a .Net application. So I gave this up.

With regard to "another tack", I don't know of anything, but then I am merely a tourist in the .NET and C# district. Maybe some of the friendly locals might know.

I found that Visual Studio has a tool accessible from the context menu to generate the interface. I run into obstacles often when I build a C# library for COM and try to use it in Excel. I have two such libraries with interfaces that appear to be identical in format. One works with Excel, the other does not. However, the one that doesn't work using an interface works OK when I remove the interface. But then nothing is available for VBA intellisense. And the functions don't show in the object explorer with either version. Is there a good book or reference that carefully and fully explains building C# libraries for use with Excel VBA?

Hi. What I'm trying to accomplish is to call this class, pass some controls and values and then have the new object update the existing control.
Help with this would be appreciated? Maybe it is not possible since I cannot pass the handle value to the class?
The error is a little misleading as the control is already created?
private void btnGroupsForUserTest_Click(object sender, EventArgs e)
{
progressBarControl pbarcontrol = new progressBarControl();
pbarcontrol.pbarIncrementValue = 1;
pbarcontrol.pbarMaximum = 100;
pbarcontrol.pbarThreadSleepIncrement = 250;
pbarcontrol.pbarObject = pBarGroupsForUser;
pbarcontrol.pbarLabel = lblGroupsForUserStatus;
progressBarIncrementer = new Thread(new ThreadStart(pbarcontrol.pbarIncrementFunction));
progressBarIncrementer.IsBackground = true;
progressBarIncrementer.Start();
}
public class progressBarControl : FormGroupMemberShipCheckingTool
{
public ProgressBar pbarObject;
public Label pbarLabel;
public int pbarMaximum { get; set; }
public int pbarIncrementValue { get; set; }
public int pbarThreadSleepIncrement { get; set; }
public void pbarIncrementFunction()
{
int incrementValue = pbarIncrementValue;
do
{
this.Invoke((MethodInvoker)delegate()
{
if (incrementValue < pbarMaximum)
{
pbarObject.Value = incrementValue;
pbarLabel.Text = incrementValue.ToString() + "% complete";
Application.DoEvents();
}
});
incrementValue++;
Thread.Sleep(pbarThreadSleepIncrement);
} while (incrementValue < pbarMaximum);
}
}

The progressBarControl control has been created, but the window handle for the control has not. You create a new instance of the control, but never show it anywhere, so it never creates a window.
Try using pbarObject.Invoke instead.

At a guess, you are doing something wrong. But without more information it is impossible to guess what.

First of all my apologies if this is in the wrong forum, i'm sure i will find out very quickly if it is 
So basically i am writing an API that needs to return the running date and time of tours including the offset, this format "2016-12-05T10:00:00+02:00", these tours can be in England or Italy so they run in two different timezones and should have a different offset.
Our API and DB run on servers in the US, all the running times are stored in the db as a datetime, without any offset, without anything to distinguish the timezones they run in bar the fact they are linked to different countries.
I'm just wondering what the coorect process is here, i have spent ages reading up on this and i think I'm more confused than when i started.
I am thinking that maybe i need to get the running date as a universal datetime and decrease this datetime for the English tours but i'm not sure how i can update the date to have a different offset, how to set/change the date so it knows its in a different timezone.
Any guidance, advice or suggestions of an appropriate blog/article to put me on the correct track would really be appreciated, thanks very much in advance.

IMO, you are mixing two issues, one being the storage of the time and the other being the display.
Dates and times should always be stored using a common base (e.g. UTC). The exact base is irrelevant (it could just as easily be Eastern Standard Time), but it should be consistent.
The display may depend on the location of the user (e.g. all the DB users are in the U.S.), the location of the tour (display in UK time or Italian time), etc. For example, airline schedules are always displayed using the local time at the origin (for takeoff) and at the destination (for landing).
I hope this helps.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Thanks for your reply, much appreciated.
So based on your logic could I not say that all my times are stored in Italian time but not in UTC, then try to convert them to UTC and back to the English time just for the tours in England?
|
|
|
|
|
Yes, that would work.
The advantage of using UTC for everything is that you don't need to handle switches between Daylight Saving Time and Standard Time - UTC has no Daylight Saving time. It also simplifies your code - all display times require one (and only one) conversion. Compare and contrast to the Italian --> UK case.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Im working on an Online Survey Form and a Question Builder.
You create different of question groups via the Question Builder by dragging(drag N drop) In Yes/No-questions, OptionLists and Text-input-fields. Here Is how the Question-builder looks like:(picture):
http://i.stack.imgur.com/U1RY2.png[^]
After you have created this groups with Questions, you can populate the Survey form with this Question groups. After you have created the Survey Form and added the groups of questions, the form should be assigned to all the users In the system.
I want your input on my Data-model how this should work. Below you can see my models. The thing I am a little worried about Is how the Answer-model should work.
QuestionContainer
---------------
public int ID { get; set; }
public string QuestionerContainerName { get; set; }
public virtual List<Question> Questions { get; set; }
Question
--------------
public int ID { get; set; }
public string QuestionHeader { get; set; }
public string QuestionHelpText { get; set; }
public string QuestionText { get; set; }
public virtual List<QuestionOption> QuestionOptions { get; set; }
QuestionOption
---------------
public string OptionText { get; set; }
public int RiskScore { get; set; }
public Question NestedQuestion {get; set;}
The QuestionOption Is the different of answer options/alternatives a question has.
Here comes the models for the Form Suvey
FormModel
-----------------
public int ID { get; set; }
public string Name { get; set; }
public string IntroTitle { get; set; }
public string IntroText { get; set; }
public string SupportName { get; set; }
public string SupportPhone { get; set; }
public virtual FormSection FormSections { get; set; }
FormSection
----------------------
public LicenseHolderModel LicenseHolder { get; set; }
public List<GasStationModel> GasStations { get; set; }
public List<Question> FormQuestions1 { get; set; }
public List<Question> FormQuestions2 { get; set; }
SurveyAnswers(Is this Ok??)
-----------------------
public int ID {get; set}
public int SurveyFormId {get; set;}
public int QuestionOptionId {get; set;}
public string Answer {get; set;}
Can you guys give me som Input of this? Have I missed something? As I said, Im not sure If I have got the Answer-model right. I want to store the answer on each question that the user has enterd In the form.
