I am new to Visual Studio so if this is a stupid question plese forgive me.
I used the Data explorer to create a relationship between 2 tables (Employee, EmployeeMiscData)I have in SQL server express. and Visual Studio 2005. I then drag and drop the two tables (detail Veiw) unto a form. I am able to use the binding navigator to move back and forth through the data.
my problem is when i try to insert a new record: After pressing the add new button on the navigator bar I can only insert a record in the parent table (Employee). The information entered into the other controls bound to EmployeeMiscData doesn't get saved.
I tried trapping the "AddingNew" event of the Employee bindingsource and then doing a "EmployeeMiscDataBindingSource.AddNew()". When I hit the save button I trap the event and then do this:
EmployeeMiscDataBindingSource.EndEdit();
EmployeeMiscDataTableAdapter.Update(venuesDataSet.EmployeeMiscData);
I get no error but nothing is getting saved into the SQL table.
I already spent twos looking for a solution.
thanks

I think you need to look into the code behind. Sounds like it should have worked ...

Hi,
How the Winforms are used in real world applications? Can one provide me good examples of it.
Thanks in advance

Or you could take a look at for example any application in Microsoft Office, those are pretty much real-life examples of winform applications.
|
|
|
|
|
The Microsoft Office applications are mostly written in non-managed C++, not a .Net language. So they are not Winform applications.
Take care,
Tom

You're going to have to be more specific. What database are you using? Are you doing this over a networking? What are you databinding? Break it down for us. Or try to search the articles for some basics if that is what you are looking for.

Dear Friends:
pnlChild is added to the children controls of pnlParent. However, when pnlParent is resized, its child panle pnlChild is not notified automatically. Why? Do I have to manually notify pnlChild of the resize event? Thanks!
using System.Windows.Forms
......
public class MyForm: Form
{
public Panel pnlParent;
public MyForm()
{
pnlParent = new Panel();
this.Resize += new System.EventHandler(MyForm_Resize);
}
private void MyForm_Resize(object sender, EventArgs e)
{
pnlParent.Size = new Size(.., ..); //parent panel is resized
}
public void AddChildControl()
{
Panel pnlChild = new Panel();
pnlChild.Resiz += new System.EventHandler(pnlChild_Resize);
pnlParent.Controls.Add(pnlChild);
....
}
private void pnlChild_Resize(object sender, EventArgs e)
{
... //is not called automatically when pnlParent is resized
}
}

Hi,
AFAIK if pnlChild is not anchored, not docked, and you want pnlParent to cause a
pnlChild resize, then you must invoke it, typically by assigning a new pnlChild.Size
in pnlParent_Resize().

That's nice. Have a good trip then...
... or did you mean to tell us about the problem you're having with your code??

What is up with the original post? It makes no real sense. Is there a problem in there somewheres or does the OP want people to do his work for him, so he gets praises/fame for other's efforts?

Yeah, I was thinking the same thing. Apparently his code needs to go on a "vision quest" to find the problems with itself.

thank your reply.my problem:i make a event draw a line
example
Point p=new Point();
Pen pe =new Pen(Color.Black,1);
private void mouseDown (object sender, MouseEventArgs e)
{
p = e.Location;
}
private void mouseUp(object sender, MouseEventArgs e)
{
Graphics g = this.CreateGraphics();
g.DrawLine(pe,p,e.Location);
g.Dispose();
}
this code draw a line from the location at Mouse Down to the location at the Mouse Up
When mouse move, I want alway have a line from location at Mouse Down to the location of Mouse at the moment.but when Mouse up,there is only a line.
It is similar to the draw a line in program Paint of Window.i can't write code.
If you know,please tell me quick

I write a class inherit from CDHtmlDialog, and show a HTML page
but the HTML page include a lot of CSSs,JavaScripts,
so have some blemish:
Dialog show first, and after about 2~4 secs, then the HTML page is showed
when HTML page is not showed, the WebBrowser Control area is blank,it is unsightly.
I also try:
1.Add the HTML file into .exe as a resource, but it is as of old.
2.Reduce css and js, can resolve this problem,but it is the only way???
any ideas???
thanks..

Sounds like a classroom exercise. You are supposed to figure it out for yourself. Why not make an attempt and if it doesn't work show us the code then we'll help you out.

Do your own frigging homework!
If something like this is too challenging for you, go pick a different profession because if you cannot solve this on your own, real world problems in software development will be too much for you.

I can tell you:
Console.WriteLine("12345");
Console.WriteLine("4321");
Console.WriteLine("321");
Console.WriteLine("21");
Console.WriteLine("1");
