So in that case I would not be able to use the designer to create my controls correct?

Not directly, yeah.
I can understand that you may have time and resource constraint. You can take that idea a few steps back:
1. Generalize the questions as much as possible into few types of question.
2. Create custom controls for each type of question. Expose methods/properties to set the question text, options etc.
3. Have a "Question" table or resource file that store those text for each question.
4. Have a "template" table that store Page Number, Question Order, Question Number and their associated question type in (1).
5. On displaying the questions for certain page, pull the data from template table, create the custom control base on the question type, populate the text from question table and bind/associate it with your dataset for answer updating, put them in a panel or TableFlowLayout control for display.
6. Repeat (5)when user change the page.

That sounds incredibly complicated. I know how to program this stuff but I am still relatively new. I rely mostly on the designer to create my controls. Do you have an example of where this was implemented. If I just put them on separate forms, I would just lose updating flexibility right?? Also why do I have to have a question type?? The order is predetermined. I cannot play with it, although it is likely that questions will be deleted, added, or changed. Also could I do it the easy way and then somehow use the code later in the new format?

Hi,
if a database-driven or table-driven approach seems too complex, I suggest you do the following:
- create a separate Form for each question, any way you choose (say Visual Designer);
give them all the same Size, and probably no border at all, no Close/Minimize/Maximize/SystemBox.
- create a main Form, which holds:
- a Panel (say questionPanel) with the same size as your question Forms;
- a "Previous" and a "Next" Button;
- whatever else you deem necessary.
- provide a Form variable, lets call it currentQuestionForm, initially null.
Now to show a question, this is what your code should do:
- remove the previous question (i.e. undo what follows for the old question); this includes:
- assuming currentQuestionForm is not null:
- removing it from the questionPanel.Controls collection
- set currentQuestionForm=null;
- add the new question by showing newQyestionForm:
- set currentQuestionForm=newQyestionForm
- setting its currentQuestionForm.TopLevel property false
- setting its Location to (0,0)
- adding it to the questionPanel.Controls collection
This way, your question forms live independently, and never get loaded at the same time, keeping
performance OK.

The order is not for you to play with, it's for the user to add, remove, rearrange.
bfis108137 wrote: Also could I do it the easy way and then somehow use the code later in the new format
Yes you can redo the system later on, it will just bite you back in the end, hard. But because now that you have a working application, the user will not want you to redo it because of time and effort, unless you have a really really good reason.
I have seen application that started with "keep it simple cos we want the system as soon as possible" requirement from user and eventually it expanded until the original (non)design became a obstacle for the expansion.
Anyway we are not forcing you to do it certain way. You should present the options to the user/owner about the effort needed and the flexibilities. If they still want the "simple way", let them know that maintaining it later will cost them more.

Does anyone have any coded c# examples of how this would be implemented?? and once again you guys are suggesting that I store my controls in a database basically right??
|
|
|
|
|
Hi, my reply, three up right now, works fine without a database. It uses what I would call "forms in forms".
|
|
|
|
|
What if I created a standard panel size that would be big enough to fit any 1 question into it, and I stored the panels in a collection, and then serialized the collection. Would the panels in the collection hold all the controls within it, or would it just hold the panel?
|
|
|
|
|
Hi,
if this is as a response to my earlier suggestion (with Form.TopLevel set false), then:
1. why serialize things, I never mentioned that.
2. I'm not a serializing expert, but I don't expect the Collection of Panels to automatically
keep all its Panel contents.
3. a Control (such as a Panel or a Form) that holds other Controls, can be included inside another
Control (such as a Panel or a Form), and by doing so it remains the parent of all the Controls it
was holding; basically you can build Control hierarchies the same way you build file/folder
hierarchies in a file system.

Hope someone can help. My problem is that the appearance of the buttons is different when I launch the application after I do a Windows Install. When executing from Visual Studio, the individual buttons are not shown. After installing from an msi file (both on my and other computers), the GUI changes. When I start the application from the installed map (c://programFiles), the buttons are changed. I know that this is not caused by any of the dlls in the install map (since I copied them from my own map by hand to test this). When I changed the name of the application in the install map (c://programFiles) then the buttons look as they should. So, there must be some connection between some data base and the application which causes this to happen (and this connection is somehow dependent on the original name of the application). How, can I prevent this from happening? Is this some sort of a bug in VS? Vista?
I am using VS 2005 for .net on Vista, working with Windows Forms, and using C#.
Have been surfing the net like a madman to no avail so Any ideas? anyone?

A Database? No, the only connection to a Database would be one the developers created. Nothing in Windows or .NET or Windows Installer is going to generate some undesired-unknown connection to a Database the developers are not even aware of, period.

I am not familiar with the term "install map" and a google search is not finding it either. Are you making that up? Don't make up your own terminology for posting in forums, people will not understand what you are talking about. Read and study the technology you are working with so you can use the terminology that people will understand.

Hi again,
What I meant by "install map" is the place to which the msi file will install the application. In most cases (as in mine) the default is usually to the "Program Files" map. And no I don't know for sure that there is some sort of connection between the name of the installed application and some sort of install data base (possibly the msi file) but that seems like a logical conclusion since the application behaves as it should when I change its name in the map where it installs under c://program files.
My question is: how do I prevent this behaviour (the changed appearance of the buttons) since it would not be reasonable to ask the user to change the name of the application after installation?
Best Regards,
Katalin

folder. That's the word you are substituting with "map". Program Files is a folder, not a map.
Katalin21 wrote: there is some sort of connection between the name of the installed application and some sort of install data base (possibly the msi file)
Well an MSI file is a database, but no your application has no "connection" to it. Unless of course you are not talking about a Database Connection[^] and we are having a terminology communications problem like with folder and map. The Windows Installer runtime uses the MSI database to perform the installation.
Also what do you mean by the "name of the installed application"? Are you talking about the executable file name? MyApplication.exe

Yes, if, for example the installed application were to be called "MyApplication.exe", then the name of the installed application would be "MyApplication".
When I change that name to "MyApp" in the folder: "Program Files", which is the place where it got installed then, the appearance of the buttons is as it should be - as it is when I execute the application from inside VS. So, my question is: What do I have to do to insure that the GUI does not change in the installed version.

Katalin

What happens if after that, you change it back?
Also in your first post you said the same about the "appearance" of the buttons but also said this:
Katalin21 wrote: When executing from Visual Studio, the individual buttons are not shown.
So could you clarify that and also clarify what is different about the "appearance"?

If you have some code that will take some time you can look into the BackgroundWorker.

I've created a custom control, and a custom collection. I've also implemented a CollectionEditor so I can add items to the collection at design time.
In the Paint method of my control, I take each item in the collection and paint them much like a ListView in details mode.
My question is this:
When I add a new item to the collection, I need the Paint method to be called. I've found that adding or editing my collection through the CollectionEditor is not causing this to happen. As a reference- if you add an item to a ListView through the CollectionEditor setup for the Items property, you will see that as soon as you edit a property, the listview is updated in Visual Studio's designer. Mine is doing nothing when I edit a value... Does anyone know how the CollectionEditor should notify the control to repaint itself?
I don't think it will help to paste my code here, since this is more of a general question but here is my property with ample opertunity to cause a repaint:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[Editor(typeof(AccentListViewItemCollectionEditor), typeof(UITypeEditor))]
[RefreshProperties(RefreshProperties.Repaint)]
public AccentListViewItemCollection Items
{
get { return _Items; }
set
{
_Items = value;
pnlContent.Invalidate();
pnlContent.Update();
this.Invalidate();
this.Update();
}
}
Any advice wold be greatly appreciated! Thanks!
