Oohh.. Bad idea - the forum guidelines clearly ask people not to cross post.
Deja View - the feeling that you've seen this post before.

I have a ListView in details view. I need the item to be in a different position than the default one so I have written de code for DrawItem event. The items show in the correct position but when I select one and move to another one the control doesn't refresh its contents very well.
This is the code in the DrawItem event
Rectangle r = e.Item.Bounds;<br />
<br />
int charIndex = this.richIzquierda.GetFirstCharIndexFromLine(Convert.ToInt32(e.Item.Tag));<br />
<br />
r.Y = this.richIzquierda.GetPositionFromCharIndex(charIndex).Y;<br />
<br />
if (e.Item.Selected)<br />
{<br />
e.Graphics.FillRectangle(Brushes.Blue, r);<br />
e.Graphics.DrawString(e.Item.Text, e.Item.Font, new SolidBrush(Color.White), r);<br />
e.DrawFocusRectangle();<br />
}<br />
else<br />
{<br />
e.Graphics.DrawString(e.Item.Text, e.Item.Font, new SolidBrush((sender as ListView).ForeColor), r);<br />
}
This is the control shown on screen Link
How can I fix this problem? Thanks

I don't know if the above question is correct, my english it's not very good.
however, i'm trying to make a safe thread call to a form :
I have declared a chatForms array with name (chatsAvailabel), so when i want to show
one of them i call the fuction ShowForm with a parameter that specify the index of the
form in the array.
delegate void ShowFormCallback(int index);
private void ShowForm(int index)
{
if (this.chatsAvailabe[index].InvokeRequired)
{
ShowFormCallback tmp = new ShowFormCallback(ShowForm(index));
this.chatsAvailabe[index].Invoke(tmp);
}
else
this.chatsAvailabe[index].Show();
}
but the problem occures when the InvokeRequired is true in if bolck, i must declare an
instance from the ShowFormCallback delegate to use with invoke, but how could i send
parmaeter index again along with this delegate instance.
thanks in advance

what about this style? :
private delegate void ShowFormCallback (int index);
private void ShowForm (int index)
{
if (this.chatsAvailabe[index].InvokeRequired)
this.chatsAvailable[index].Invoke(new ShowFormCallback(ShowForm),new object[] { index });
else
this.cahtsAvailable[index].Show();
}

it's do work without error or exception, but the new showed form freeze(not rsponding) on screen which mean that the operation it's not thread safe.
|
|
|
|
|
maybe ShowDialog() can help ? (not just Show())

You are not correctly using delegates. Try this:
private void InvokeShowForm(int index){
if(InvokeRequired){
Invoke(new ShowFormCallback(ShowForm), new object[]{index}));
}
else{
ShowForm(index);
}
}
public void ShowForm(int index){
chatsAvailable[index].Show();
}

Hi
I am developing a windows application which is having login and other pages as winforms.
In the login page I having an option for the user to change his password. If i click that change password button Im openning the change password URL in a webbrowser control. In that user will be asked to first login, and after login user will directed to change Password screen. But when the user logged in and closed that window and if the user clicks again the changepassword button then webbrowser control directing hime to change password screen instead of Login page. (is like kinda cached page). but i tried of clearing cache, used Activex control nothing works out.
Finally i saw the everytime i open the URL usign webbrowser control it is creating a Hidden IE window. (usign spy++). so that webbrowser is directing to the alredy opened page. How to close that hidden window? can i use its handle to close that one or any other solution here?
Thanks in Advacne

Thanks for the reply, But this doesn't help, Still the Browser directing URL to logged in page instead of Login page.
I am using the code like this
CloseWindow(frmChange.axWebBrowser.Handle);

Some code would be useful.

hi
i'm not sure, but maybe you haven written an
UPDATE SQL string.
if you want to update your database, you have to
use TableAdapter.Update(), and if there is no
UPDATE SQL string, you got an error.
but as i wrote i'm not sure, because i'm
not good in SQL an databases generally
hope this helps you
