Hi,
i am developing a custom control in C#.
I am coding the design time side of the control, but i have a problem.
I added some verbs to the control. Everything works fine in design time, but in runtime the code does not persist.
I add components with
mDesignerHost.CreateComponent(typeof(myComponent), name) as myComponent
where mDesignerHost is the IDesignerHost for the designer.
Only the creation of the component persists in runtime, but the rest of the code does not.
What's wrong?

What are the speed differences (if any) between using Textboxes,Radiolists, Labels etc to build a form as opposed to using a variety of custom controls to build the same form? (One of the custom controls would be, for instance, a label and textbox).
|

That depends on the quality of code in the custom controls. But, all thing being equal, there isn't any difference at all since both sets of controls will ultimately derive from the same base class, Control.

Hi All.
can any one help me, How to filter/sort records in a datagrid according to the values which I type in a text box,
my problem is i have a dataset populated and am setting it as data source to my grid.my requirement is i need to sort the grid at runtime as and when i type some text in a textbox (relates to a col in the grid), associated in the same form, and then after filtering i should be able to update the colums in the grid.
select query is to be performed once only, and i need to work with the availabe dataset to filter/sort records

Create a DataView from your DataTable and set that as the DataSource for your DataGrid. Then change the DataView.Sort based on the text in your textbox.

Hi all,
I have an Outlook Add-In that uses it's own shim for an AppDomain and often (don't you just hate it when that happens) Outlook acts strangely.
What does strangely mean? Two things mostly; On moving off in a email in the .pst file that mail is deliver to, the mail is not marked as read. Secondly when dragging a "still marked as unread even though I have read it" mail message from the folder it is in to another folder you get the message "Can't move the items. The item could not be moved. it was either already moved or deleted, or access was denied". Interestingly this message does get copied, it's just the delete afterwards results in the error. Deleting the message manually afterwards is fine.
I assume that my Add-In is being called and throwing an exception that is resulting in the delete after copy failing but I have stripped out everything that it has and it still happens.
Is there a way to get Outlook to tell me what is going wrong inside?
Thanks,
_Goose

Hi there.
I ran into some problems. I created a small form (f1) and on it there is a button. When the button is pressed a second form is created (f2) and springs up. I can´t seem to create a menu for this new form (f2). I also put a simple Label control on f2 just for fun. I put some code into the eventhandler for the button but then all I get when the button is pressed is a menu on the underlying form (f1), not on f2 like I intended 
Here is what happens when the button is pressed:
Form f2 = new Form();
f2.Show();
f2.BackColor = Color.White;
Label pa = new Label();
pa.Text ="Just for fun";
pa.Location = new Point (40, 110);
f2.Controls.Add(pa);
MainMenu MyMenu = new MainMenu();
MenuItem m1 = new MenuItem("File");
MyMenu.MenuItems.Add(m1);
MenuItem subm1 = new MenuItem("Hello");
m1.MenuItems.Add(subm1);
subm1.Click += new EventHandler(menu_selected);
Menu = MyMenu;
Can someone please help me ?

You are adding the menu to the form that contains the event handler there. Try:
f2.Menu = MyMenu;

It works, thanks a lot

Hi, I want to create a setup project. My c# project uses a Microsoft Access Database. Som how and where should i add this database file to my setup project so that the setup will then work?
Thanks!

You need to add it to the files you want to install. You can select the Files view through the project explorer (some buttons at the top of this explorer).
Be sure that the application loads the database from the directory it is running from (the application directory  )

Hi,
I can translate my application using the procedure described in the MSDN article 'Walkthrough: Localizing Windows Forms'. In that article, one one language is set, by instantiating a CultureInfo() in the constructor of the from and setting it on the current thread's CurrentUICulture.
But now, how do I dynamically (at run time) change the language that the UI is show in? I've tried calling InitializeComponent() after setting Thread.CurrentThread.CurrentUICulture but that doesn't work. I know I can have the user close the application and restart it so that I can set the correct CultureInfo() at the start of the program, but is there another way? Thanks.
cheers,
roel

You can set the currentculture property of the thread your in.
Thread.CurrentThread.CurrentCulture = New CultureInfo("nl-NL", False)
|
|
|
|
|
Hi,
Thanks, but that only works when doing it before the UI is created. I'd like to change the language of the labels, buttons etc. while the application is already running (through a menu option).
cheers,
roel

If you put the different language versions of your lable text etc. into separate resource files, you can change them on the fly by reloading the appropriate resource file and modifying the appropriate text yourself. Load the initial resource file at startup using the current culture, then reload when the user changes the language selection. A little painful, as you will have to manage retrieving all the appropriate strings by key, and updating the pertinent controls yourself, but it will work.

How to execute a function on the server upon closing of the application on a client side?
I have used the 'Page.Unload' command, but it is executing upon loading of the page and not upon the closing of that page.
What I need to do is clean up a 'LOGIN' table that carries the user ID and the SessionID if:
a- the user closed the appliaction by clicking 'x' at the upper right corner instead of the controlled 'logout' button, or
b- the user left his system un-attended and the session timeout after 30minutes.
Since in both cases, if he tries to log in again, it should not allow him if he already has a record in the 'LOGIN' table.
Any help on this is appreciated.

You cant detect if the user has closed the window.
Fill the Session_End method in Global.asax.(cs|vb) this can handle the things you want to do correctly.

It is not going to that method!! I have placed a break point in the method, but it never goes to it! I even tried the Application_End, and it does not go there either untill all users are logged out, which is not my case.

Frndz,

Hi Frndz,
I don't quite get what you exactly have in mind.
You can always build a dataset containing two rows and the amount of columns needed for your data.
Bind the DataGrid to that DataSet and there you go. The DataGrid layout you need.

In my program an animation control is placed on the windows form. And the Avi file will be played when the form is loaded. Here the file path of the Avi file is assigned to the file name property of the animation control.
My problem is I want to make the program work when the program is deployed on different machines where the file path will be different.
I am placing the Avi file the with in the project folder it self.
