Hi,
I have a setup for MDI forms.
When I open an MDI client , i want the parent MDI opacity to be 50 % and back to 100 % when I close the client form.
My problem is that I am unable to access the Parent MDI form.
????????
Looking froward for your response.
Thank you!

you can set parent form opacity to be 50% after show the child form, and add event FormClosed on your child form, in that event set back parent opacity to 100%.
but...
when you set parent form opacity this will also affect to your child forms.
hope it helps

Two solutions both from the parent not the child.
1. Subscribe to the child's FormClosing event (in the parent form after creating the instance).
2. Use the parent form's MdiChildActivate[^] event - this is fired every time a child is opened or closed.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Expect everything to be hard and then enjoy the things that come easy. (code-frog)

use this.Parent.Parent from your MdiChildForm

Good Evening alL
I have an ASP.NET Front end that seaches the Dates in certain Ranges. here is my Data Layer.
public DataTable Get_Date_by_Month(String Username,String Datefrom, String Dateto)
{
con = new OleDbConnection(strcon);
DataTable Details = new DataTable();
da = new OleDbDataAdapter();
cmdselect = new OleDbCommand();
cmdselect.CommandTimeout = 0;
cmdselect.CommandText = "SELECT [Details].[Transportation],[Details].[HOUSING], [Details].[FEEDING], [Details].[UTILITIES], [Details].[INSURANCE],[Details].[TELECOMMUNICATION],[Details].[Entertainment],[Details].[FUEL],[Details].[CLOTHING],[Details].[EDUCATION],[Details].[Miscellaneous],[Details].[BASIC_INCOME], [Details].[OTHER_INCOME] FROM [Details] INNER JOIN USERS ON Details.[P_ID] = [USERS].[ID] Where Details.Username = ? And Details.[DATE] Between ? AND ? ";
cmdselect.CommandType = CommandType.Text;
cmdselect.Connection =con;
da.SelectCommand = cmdselect;
da.SelectCommand.Parameters.Add("[Username]", OleDbType.VarChar, 30).Value = Username;
da.SelectCommand.Parameters.Add("[DATE]",OleDbType.Date, 30).Value = Convert.ToDateTime(Datefrom).ToShortTimeString();
da.SelectCommand.Parameters.Add("[DATE]", OleDbType.Date, 30).Value = Convert.ToDateTime(Dateto).ToShortTimeString();
try
{
con.Open();
Details.Clear();
da.Fill(Details);
}
catch(OleDbException)
{
throw;
}
finally
{
con.Close();
}
return Details;
}
<pre>
but now if i try to Search between Valid Ranges, it Brings nothing to the DAtagrid. Am Using Access 2003

change those line to :

da.SelectCommand.Parameters.Add("[DATE]", OleDbType.Date, 30).Value = Convert.ToDateTime(Dateto);

Hi
i have this code to create a new control (inherites from Panel) and when user over it, click mouse and drag, a new rectangle create and resize to fit with mouse position cordination:
public partial class Stage : Panel
{
int originX = 0;
int originY = 0;
bool dragging = false;
public Stage()
{
InitializeComponent();
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);
}
protected override void OnMouseDown(MouseEventArgs e)
{
this.dragging = true;
this.originX = e.X;
this.originY = e.Y;
Graphics g = this.CreateGraphics();
g.DrawRectangle(new Pen(Brushes.Red, 4), this.originX, this.originY, this.originX, this.originY);
this.Invalidate();
base.OnMouseDown(e);
}
protected override void OnMouseMove(MouseEventArgs e)
{
if (this.dragging)
{
int posX = e.X;
int posY = e.Y;
Graphics g = this.CreateGraphics();
g.DrawRectangle(new Pen(Brushes.Red, 4), this.originX, this.originY, posX, posY);
this.Invalidate();
}
base.OnMouseMove(e);
}
protected override void OnMouseUp(MouseEventArgs e)
{
if (this.dragging)
this.dragging = false;
base.OnMouseUp(e);
}
}
but at runTime, it work so bad with flicker and when mouse button released. not any rectangle exist in Stage control.
can anyBody help me to find out how to create rectangle whith drag and drop correctly ?
thanks

Ok, first - don't draw using CreateGraphics. Override the OnPaint method, or register for the OnPaint Event.
Second, you can set double buffering on your form, which should reduce filcker (There should be a property on your form for this)
And the reason there is no rectangle when you've finished.. well, its because your no longer drawing any rectangle.
Rectangle rect = new Rectangle(0,0,0,0);
OnMouseDown(...)
{
this.dragging = true;
rect.X = e.X;
rect.Y = e.Y;
}
OnMouseUp(...)
{
this.dragging = false;
}
OnMouseMove(...)
{
if(this.dragging)
{
int width = e.X - this.rect.X;
int height = e.Y - this.rect.Y;
rect.Width = width;
rect.Height = height;
this.Invalidate();
}
}
OnPaint(...)
{
e.Graphics.DrawRectangle(myPen, rect);
}
Or something like that. You have to store the rectangle your creating, so that it can be drawn later on. It won't just stay there.

Hey guys.
How can we write
if (str.Length > 250) str = str.Substring(0, 250);
with ? operator ?
Thank you.
|
|
|
|
|
The ? operator is like an if-else statement with the syntax:
Condition ? Statement1 : Statement2.
Where Statement1 is the code executed if the condition is true, and Statement2 is the code executed if the condition is false.
So in your situation, something like:
str = str.Length > 250 ? str.Substring(0,250) : str;
should do it.

Or
str = str.Substring(0, Math.Min(str.Length, 250));

The expression str.Substring(0,str.Length) is rather pointless, as it returns a string identical to str.
Just do:
str = str.Length > 250 ? str.Substring(0,250) : str;
Despite everything, the person most likely to be fooling you next is yourself.

Hi All,
I'm just setting up a new solution for a refactoring exercise. I have a few projects in the solution that all have post-build events to copy them to location where I'm compositing the application files.
How do I set-up Visual Studio to debug c:\app\app.exe when I hit F5 instead of it simply starting the .exe in the bin\debug directory?
Cheers,
|
|
|
|

Under the project's properties go to the Debug options, select "Start External Program" and put the path to your app in the text field.

I'm at a loss. Hoping someone can help.
I'm creating a custom control which inherits from Control (not sure if that's where I went wrong to start with) but here's the problem.
Based on a property which holds an array of strings, a certain number of panels are added to the control.
When the setter function of the string array property is called, the panels are added as follows:
this.Controls.Clear();
foreach (string s in myStrings)
{
Panel newPanel = new Panel();
newPanel.Name = ...;
newPanel.Location = ...;
newPanel.Size = ...;
newPanel.Paint += new System.Windows.Forms.PaintEventHandler(panelTab_Paint);
this.Controls.Add(newPanel);
}
And the paint function callback looks something like this:
private void panelTab_Paint(object sender, PaintEventArgs e)
{
}
So the problem is that, inside the function above, the value for e.ClipRectangle is {X = 0 Y = 0 Width = 0 Height = 0} which is obviously not right. The size of the Panel which can be obtained through sender is a valid size but why is the ClipRectangle of the PaintEventArgs value zero?
|
|
|
|
|
I'm not sure, but you could also check e.Graphics.Clip, e.Graphics.ClipBounds and e.Graphics.VisisbleClibBounds. You probably want to try ClipBounds though.

The thing is, I'm not so much interested in obtaining those values, I mean I can quite easily do that by using (sender as Panel).Size and (sender as Panel).Location. I do want to be able to paint on the panel with e.Graphics.DrawLine(...) and such but as long as the e.ClipRectangle value is zero, nothing I draw on the panel will be successful as it falls outside of the clipping rectangle.
|
|
|
|
|
Oh bother! It seems my problem is bigger than just that. But at least, I suspect that if I can sort this one out it will be a sollution to the above as well.
I've now tried to implement an OnClick event for the Panels by adding this:
newPanel.Click += new EventHandler(panelTab_Click);
just before this:
this.Controls.Add(newPanel);
and defining panelTab_Click as follows:
private void panelTab_Click(object sender, EventArgs e)
{
}
However, even though the tabs are being added to the control they wouldn't respond to mouse clicks and the function above is never called. I'm reasonably sure that I'm adding the event handler correctly so I think my problem is with the way I'm adding these panels to the control in the first place. Any ideas?

hi every body
i want know how can i send data to database without repetition

string z ="tom";
string a="Axe";

i want send it one time only
how can i do this ??

Please stop using the bold font for your postings, it's annoying.
You could put all your strings into a hashtable, this will ignore duplicates:
Dictionary<string, string> strings = new Dictionary<string, string>();
strings[s] = s;
strings[x] = x;
strings[v] = v;
strings[z] = z;
strings[a] = a;
Then when adding them to the database simply iterate over the Values collection.
regards
