I am trying to keep a window open by handling the MouseMove event. However, the event is only ever raised when the cursor is over the splitter bar between the grid and description. Any help/suggestions?

I take it that you're capturing the Form.MouseMove event?
If so then what's happening is that the Grid and the Description are on top of the form and are blocking the mouse-movement for the form (basically).
The simplest way around this would be to set the Grid.MouseMove and Description.MouseMove events to be handled by the same handler as the form.
To do this, select the grid, click the events tab on the properties window in the form designer. You should be able to select the Form_MouseMove (or whatever it's called) routine in the MouseMove combo-box for the grid (they have the same delegate handler so they're compatible).
Repeat the process for the description.

Your datagrid usualy is bound to the dataTable that holds the data shown into you grid. Sou you must intercept the changes that ocur into the dataTable. This can be obtained with these events :
DataTable.RowChanging/DataTable.RowChanged
DataTable.RowDeleting/DataTable.RowDeleted
Intercept change to the table and update you collection.
protected internal static readonly ... and I wish the list could continue ...

Hello, I am looking for a way to get something similar to the tables that are seen in Word. I can draw a table onto a RichTextBox control using the appropriate RTF syntax, but what I would ultimately like is the ability to resize columns and rows using the mouse.
Does anybody know how this is done? Is there a third party control that allows this to happen?
I suppose you could trap mouse movement and such, but this seems really hard, because how would you even know where the table is within the textbox?
Thanks in advance,
Eric

Hello,
When coding a dialog box in C#, naturally there is going to be code that loads the dialog box with its initial values, responds to user input, and then retrieves the new values for use in the application.
Is it more appropriate to put this code into the Form class of the dialog box itself, or to have a separate class whose job it is to control the dialog box, and interface with it?
Thanks,
Rich

IMO, neither. Use data binding to connect an autonomous class that contains the properties for the data with the dialog. The data binding ensures that neither the dialog nor the underlying container class needs to know about each other, which makes your application more flexible and extensible. Here's[^] an article I wrote on the subject.

How do i change the background colour of a tabcontrol? I looked at msdn and i found .BackColor property but it doesnt seem like its working...
|
|
|
|
|
In order to draw my own font on the tab page i have overridden TabControl.DrawItem using the following:
private void DrawOnTab(object sender, DrawItemEventArgs e)
{
Graphics g = e.Graphics;
RectangleF tabTextArea;
TabControl tc = (TabControl)sender;
SolidBrush brush = new SolidBrush(Color.Black);
Font fnt = new Font("Microsoft Sans Serif",14F,
System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
foreach (TabPage tp in tc.TabPages)
{
tabTextArea = (tc).GetTabRect(tc.TabPages.IndexOf(tp));
//find out how to draw the string center
g.DrawString(tp.Text.Replace('_', ' '), fnt, brush, tabTextArea);
}
}
Right now it draws the text aligned to the left, how do i draw the font center? do i have to calculate the length of the string manually? How do i do that?

Use the version of Graphics.DrawString() that allows you to specify formatting options. See this[^] link.

I am using the cards.dll in my application as suggested at this website:
http://www.publicjoe.f9.co.uk/csharp/card06.html
The card shows up just fine on the form but i get this weird message immediately after drawing:
-----------
A call to PInvoke function 'CardMgr!cards.cardsdll::cdtDraw' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
------------
I have no clue what information to include in this to even begin to addrss the problem.
Any ideas how to address this?
Thanks!

Thank you so VERY VERY VERY much, Ravi.
That resolved the problem ... the DLL returned an integer ... the interface expected a bool.
I will so inform the author of the website ... thanks again.

I want my tabpage to be scrolled by using my own button, so I have the following:
if (tabControl1.SelectedTab.VerticalScroll.Value - 200 > tabControl1.SelectedTab.VerticalScroll.Minimum)<br />
{<br />
tabControl1.SelectedTab.AutoScrollPosition = new System.Drawing.Point(0, tabControl1.SelectedTab.VerticalScroll.Value - 200);<br />
}else<br />
{<br />
tabControl1.SelectedTab.AutoScrollPosition = new System.Drawing.Point(0, tabControl1.SelectedTab.VerticalScroll.Minimum);<br />
}
this is the event handler method to clicking the button for scrolling down
When i click the down button, it only moves down once, the second time i click it it doesnt work any more...
this happens when i have the AutoScroll disabled, but when i have autoscroll enabled, its fine
why!?
Can someone help me? is there anyway to enable the autoscoll, but hide the scroll bar?! maybe override the onPaint method for tabControl?

I have a database in which users can upload files for storage and whatnot. In my windows forms app to download/upload I am displaying the files that the user has uploaded. In the ListView I would like to display the appropriate icon for each file.
ex: If they have Microsoft Word installed, it should display a Microsoft Word icon. If not just a plain file icon should be displayed.
How would I do this?
Any help is appreciated.
|

Perhaps you could call SHGetFileInfo to obtain the file's icon index in the system image list (as well as its display name, eg: "Microsoft Word document"). You can pass a fictitious filename (with a matching extension) to SHGetFileInfo.
See this[^] link for how to call ShGetFileInfo from your WinForms app.

Hi! I have a newbie question: How do I get this code to compile and output "derivedclass"? The classes may only have static methods.
class BaseClass
{
static string _name = "baseclass";
static string GetName()
{
return _name;
}
}
class DerivedClass : BaseClass
{
static string _name = "derivedclass";
}
Console.WriteLine(DerivedClass.GetName());
I'm stumped so any help would be appreciated.

Use:
static new string GetName() {...}
|
|
|
|

Unfortunately, that doesn't work.

first create second form on your first form after then you can call public variables of your form1 using Form1.yourPublicVar . i mean on buttonclick event write code like this
mySecondForm Form2 = new mySecondForm();
Form2.yourPublicVar = what you want;
