i am working on windows form where
i have 7 dropdown list present. same items is get display in all dropdownlists
but my querry is that when i select any item in 1st dropdownlist...
remaining dropdownlists should not display that item. in this way if i select any item say surname in 2nd dropdown list that selected surname should not be present in remaing 6 dropdown list.
other dropdown list should display the data except the selected one from previous dropdownlist.
what i did is
i created an arraylist and fill the data in it...
On dropdown listclick i take the selecetd item
store it in string and remove that string from arralist
and bind the data in dropdownlist.
but its not working its going in infinity loop as well.
is there any other method to solve my problem...
Thanx,

{ RemoveData();
}
public void RemoveData()
{
ArrayList arr = new ArrayList();
arr.Add("UserName");
arr.Add("City");
arr.Add("State");
arr.Add("Country");
arr.Add("Expertise");
arr.Add("AboutMe");
arr.Add("Rank");
arr.Add("Score");
if(drpuname.Enabled)
{
drpuname.DataSource = arr;
string str = drpuname.SelectedItem.ToString();
drpuname.Items.Remove(str);
}
if(drpcity.Enabled)
{
try
{
string str= drpcity.SelectedItem.ToString();
arr.Remove("str");
drpcity.DataSource = arr;
drpcity.Items.Remove(str);
}
catch(Exception ee)
{
string msg = ee.Message;
}

i know GDI is so slow but how does software as photoshop or fireworks use to do drawing operations?
|
|
|
|
|
without using .NET, thats for sure!
Photoshop and other graphics editing software is not written on the GDI library, they use native OS features and bespoke libraries.

For example, I am a pretty certain the Adobe have their own (bespoke) image manipulation library used for Photoshop. They probably reuse it, in parts, for Photoshop Elements.

How to add menu to Window Form?
How to get height/width of the form?

You're seriously struggling with this?? Have you even tried?
Add a menu to the form by dragging an instance of MainMenu onto your form from the toolbox in visual studio.
As for your second question, and you may be massively surprised by this, a form has a Width and Height property

You'll find MainMenu in the toolbox, in Designview of your form.
As for height/width of your form,
you can use this.Height and this.Width in the form-code.
('this' being the form)

I am trying to use the Webbrowser control that is available in VS 2005 C# Express (.NET 2.0) to automate navigation through a set of web pages programmatically. I've run into two situations where I cannnot access the OuterHtml property of an HtmlElement. Looking at the debugger seems to say that some kind of underlying exception occurs.
1. I want to select an item in a listbox on a web page by changing the OuterHtml of two of the member elements from:
to
The attempt to remove the 'selected' string from the first entry fails completely and even messes up the entire listbox
2. I want to iterate through the frames on a web page to find the one I want to enter some text into. When I try to access (read, not write) the OuterHtml property of a frame to see if it is the one I want I see some kind of access violation in the debugger. Shouldn't this work?
Does it make sense to try to use the unmananged interfaces IHTMLDocument, IHTMLDocumet2, etc. when the Webbrowser fails like this? Can I mix the use of the Webbrowser control with use of the unmanaged interfaces?
|
|
|
|
|
My guess is that the managed web browser is failing because the underlying unmanaged browser is failing.
You can try though; you can mix the managed layer with the underlying native interfaces. You can do this by casting the webBrowser.Document.DomDocument object to IHtmlDocument2 and going from there.

dear friend
i have worked abit with datagrid but it has the limitation of all view will be of columes and rows but i am looking for some control/way in which i have to draw some table and decribling under all that table then again a table but all in one view i.e. atleats 10 tables and 1 paragraph of simple writting against after each table
|

Okay, so if I understand you right, you need a table of rows and columns with a block of text underneath the table? (Along the lines of this[^]?)
If so, then you can still use a DataGrid (or DataGridView if you prefer) and dock a Label or TextBox to the bottom of the parent control.
The DataGrid also has support for hierarchical tables (although AFAIK was removed in DataGridView) if that might better.

Hello Graham
Special thanks for your help but i an unable to understand u fully, might be my lack of knowledge at gridview.
just for more clearification please have a look at the snap
http://www.geocities.com/junaid_qau/view.JPG[^]
http://www.geocities.com/junaid_qau/view.JPG
this is what i am trying to make and i need help in top right panal.
that panal will have data from the DB in different languages ( arabic, English, french etc ) as per user sellection .
so i was thinking to have some controll in which i can display that data in a user readable form.
it may be if possible to create well formated RTF/html in run time and so in rtf/HTML control etc. but that will effect the performance i think
anyhow any other ideas...
keep in mind i can use ONLY ONE panal in that GUI
thanks Regards

I have an Windows app that allows users to save "bookmarks", pages they have been, and then navigate back to them. That all works. In addition, we have restricted them to 15 bookmarks, and if they select a 16th, the first one in is popped out. I am attaching a Context Menu to a button on the toolbar.
Now they would like to be able to delete an individual bookmark. I have the code working to dynamically add the bookmarked pages, to a sub-menu item for deletes. I even have the code working to delete the item from that MeunItems collection. When I check the count of that collection, it is correct, and when I click my code to add another bookmark, the old ones appear, and the one I deleted is gone. HOWEVER, when I go through the delete code, and then click on the button, none of the entries appear. Here's the code:
Load the Menu Items, both in the Main menu and the Delete Bookmarks
private void button1_Click(object sender, System.EventArgs e)
{
for (int i = 0; i < 6; i++)
{
MenuItem myMenuItem = mainToolBar.Buttons[0].DropDownMenu.MenuItems.Add("Added Item " + i);
this.mainToolBar.Buttons[0].DropDownMenu.MenuItems[myMenuItem.Index].Click += new System.EventHandler(AnotherMenuTestMethod);
deleteBookmarkMenuItem.MenuItems.Add(myMenuItem.CloneMenu());
deleteBookmarkMenuItem.MenuItems[deleteBookmarkMenuItem.MenuItems.Count -1].Click -= new System.EventHandler(AnotherMenuTestMethod);
deleteBookmarkMenuItem.MenuItems[deleteBookmarkMenuItem.MenuItems.Count -1].Click += new System.EventHandler(DeleteMenuTestMethod);
}
}
Here I'm trying to delete a specific one (just to see how to do it)
public void DeleteMenuTestMethod(object sender, System.EventArgs e)
{
MenuItem myMenuItem = (MenuItem)sender;
deleteBookmarkMenuItem.MenuItems.RemoveAt(3);
MessageBox.Show(deleteBookmarkMenuItem.MenuItems.Count.ToString());
}
As I mentioned the count is right, but when I click on the button, NOTHING appears in the Delete Items.
<added>By the way the 'deleteBookMarkMenuItem' variable is a global one for the form.
I'm obviously missing something, anyone spot it?
THANKS!

As it turns out, it appears this is a "bug" in .NET 2003, and has been fixed
in 2005. I took the code as is into VS 2005 and it works fine. As we are
moving there in the next month or so, I guess I'll just wait to finish this
then.

Hi,
I've got a generic class (Binary Tree)
public class ABB<T> : ICloneable where T : IComparable/*, ICloneable*/ {
.
.
.
}
I adapted it so items that are not ICloneable can be introduced into the tree, but if they are not ICloneable and they are not like (int, float...), because is another class that is not ICloneable, I'd like to print a:
#warning If the object is modified after introducing it into the tree, the object that the tree has saved will be changed too (if T is not a primitive type). If you wan't to solve this, make the class T implement ICloneable methods, and a copy of the original object will be saved into the tree, instead of copying its memory address (as is happening right now).
But this warning only MUST BE SHOWED if the class T that has been instantiated like:
ABB<ClassWhichIsNotICloneable> object = new ABB<ClassWhichIsNotICloneable>();
Well, it would be showed with old types too (int, float...) but there's no problem since it is a copy of the original type what is introduced onto the tree (as the warning says). As this:
ABB<int> object = new ABB<int>();
Well, int is not ICloneable, but there's no problem with it.
THANK YOU.

I don'think that the preprocessing facility in the C# IDE is flexible enough to satisfy your requirements. In the class's constructor you could test the runtime type of T, and if it falls into the category which requires a warning, use Debug.WriteLine to specify the warning. An advantage of this technique is that the developer's output window in VS won't be polluted with your warning message(s) on each build. I like a nice clean build - 0 errors, 0 warnings

Well, a clean output for clean designs. If your design (in this case, MY DESIGN) has troubles (if the class is not ICloneable), and the object that you think that is for sure can be modified by side-effects (if I wasn't able to call Clone(), then I copied the memory address), there must be a WARNING to let the programmer know that he has to be *VERY CAREFUL* with the original object, or make that class ICloneable, so warning message *WILL DISSAPEAR*.
Well, if he does well, there will be 0 errors, 0 warnings. 
Cheers !!

What does this have to do with your original question?
Keep in mind that implementing ICloneable is not always an option. If your type contains a reference to another type which is not cloneable, then your type cannot provide true deep copy semantics. In that case, your annoying warning message will not disappear.
Josh

You're just right. In that case the #warning message wouldn't be showed, and my class would't be able to provide a true deep copy, but in that case, and only in that case, the problem (the main trouble) would be that the developer that wrote it was wrong, because didn't think about implementing Clone() method to provide a deep copy.
We sometimes just have to trust in developers that are gonna use our classes, so we cannot do more than we are doing right now.
Far away, you're right, my warning would not appear when compiling.
Thank you for your comments Josh.
