Define "change". If you mean change the layout, the ReportDocument has a property, ReportDefinition, that gets you the collection of sections, etc. I'm not sure how much of this you can change at runtime, but you might be better off asking in the Crystal Reports forums at http://support.businessobjects.com/forums/default.asp?ref=devzone_main[^].
If you mean to change the data source on which to report, see the ReportDocument.SetDataSource method. Designing your reports to use disconnected DataSet objects (especially strongly-typed ones that you can build report defintions from) makes reusing your reports on different systems and with different database easy!

Hi
We have an MDI application, where we would like to limit the possible locations of the MDI child forms.
Is it possible to set up some kind of borders that limit child location to some part of the client area?
Currently we simply move the form back inside the borders if it dragged outside of the borders. Unfortunately, this has some sideeffects (e.g. client form can be moved far outside the borders before the moved event is raised)
BTW: Is it possible to disable the scroll bars that appears on a MDI parent?
Thanks, Mads

Yes, you can fix the Child form location MDI form.
You have to set the following properties in Child form
Form Location
Form Border = none
Control box= false
MaxBotton=false
MinBotton=false
Window Startup position=normal

Thanks for your reply - but wouldn't that make the form unmoveable? What we want is to be able to move the form around within a limited area.

You can set the child form boundry in Child form MOVE event.

Hi, I want to ask if there is in .NET an similar technology to the Java Applet/Servlet. And if such a thing exists pls help me with some documentation resources.

I wrote an article a long time back on another site that I'm working on porting to CodeProject as a new series. See http://www.devhood.com/Tutorials/tutorial_details.aspx?tutorial_id=388[^] for more information about hosting .NET controls in a web page. If exposed as COM control correctly (which the articles covers), you can even script them and handle events.

hi
i am currently writing an application where the user can save as much as he wants
those are splitted in A[] and B[] (String[])
a contains A name and B contains a path related to the name of A
i want that A will be shown in a listbox (all A's) and when you click on it i want a messagebox showing A and B together (the right one, e.g. A[5] and B[5]; not A[4] and B[2] or so)
i am open for all ways of saving, but i do not have an own idea how i can make this
thx

You can create a serialize class and encapsualte your class there and store your data in a XML file,for working with XML there are lots of projects in this site. Or if you do not want to store it in a XML,you can store that class in dat file.

1) You can use a ListView instead of the ListBox, and store the path (B) in the .Tag property of each ListViewEntry. When you click a name (A), you can read the path from the Tag property:
for(int n=0; n

I have a windows application which has a lot of controls placed all over the screen. I have developed it in screen resolution of 1024 X 768.
The problem is that when the resolution becomes more, the controls occupy lesser space on the screen with lot of free area. If the resolution decreases, each control requires more space on the screen and many controls go out of the screen with scroll bars being displayed.
Is there a way of dynamically resizing the form controls based on the resolution of Windows?

First: There are many applications that they fir for one resolution and warn it before run. But beyond that after your InitializeComponent() add a method that set the methods based on this resolution. You can get the resolution with SystemInformation.VirtualScreen property,and every control has its own Size property.

In addition to what Mazdak was talking about, you can also make use of the Dock property that most of the controls expose. Effective docking can help decrease those problems. If you're not starting with a clean surface, though, pay close attention to the order in which controls are added to the container's (ex: Form) Controls collectoin. They must be added in reverse order. For instance, if you have the "explorer layout" like so:
+-+---+
| | |
| | |
+-+---+ , you'll want a TreeView, Panel (to further dock additional controls), or some other control set to <cod>DockStyle.Left, then a splitter, then another control with DockStyle.Fill. The order in which these are added are in reverse of how I mentioned them:
Controls.AddRange(new Control[]
{
panel2,
splitter1,
panel1
});When you add these controls to the designer for the first time (i.e., on a "clean surface"), add them in the order that I first mentioned above. VS.NET automatically adds the most recently added control as the first control in the array above.
Just play around with docking a little bit. Anchoring to opposing sides is also helpful but while docking and anchoring share some behavior in common, they are also used to solve distinct problems (they are most like each other when anchoring against opposing and adjacent sides, but docking can't move a control relative to adjacent sides).

DockStyle in IMO is the easy way out, if you want control, use anchors.

The problem with anchors is that theyonly anchor to the parent control/form, and when the control/form shrinks the controls overlap.
The problem with docking is that the change in size is only shown in the fill'd control, and there is only one of these.
What you want is to have the control container resize the child controls, for that you need to create an "AutoSizePanel", have that dock'd fill and then set your controls on the panel.
Here is the code for the "AutoSizePanel":
using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;

using System.Windows.Forms;

Hopefully at that stage the user realises that his an idiot, and the app wont run at 20 x 40 px.

First, I am assuming that you have never dealt with marketing, as users are never idiots, and your app should run at 20 by 40. I solve it by making the controls really small, and then it becomes a hardware problem as the monitor is not able to display them properly.
Second, you should be PC and not assume that all users are male. This is assuming that you meant to type "the user realizes that he is an idiot", if not my apologies.
