Well I never had a problem with just copying the complete folder to a new PC and then opening the solution (that should only contain relative paths) - maybe you are missing some critical files that are located on another folder (for example the solution file?)?

And that got voted down, guess it wasn't the answer they where looking for.
I also have never had a problem with copying projects. They just work, wherever i put them.

Check in the Visual Studio 2005\Projects directory for the solution directory. The solution file is probably sitting in there.

Yes, the default varchar size is 4000.

Use the varchar(MAX) function to retrieve anything larger.

or use the "text" - type ( make sure to read about the limitations / gains - but I guess if the text is more than 4000 characters this type is the way to go - you don't want an index on this field right ? )

Hello!

Is there any way to work with i.e. read and write data more than 8000 characters?

Adding/Removing parent's keypressed handler on MDI child VisibleChange method

4-Dec-07 1:36

yes this is exactly what the text type is for (if you are using unicode take the ntext)

Hi, I want to disable a keypress handler of a mdi container form. I'm adding this on the container's Form_load:

this.KeyPress += new KeyPressEventHandler(Form1_KeyPressed);

and this on the child's VisibleChange event:

if (this.Visible)
{
principal.KeyPress -= new KeyPressEventHandler(principal.Form1_KeyPressed);
}
else
{
principal.KeyPress += new KeyPressEventHandler(principal.Form1_KeyPressed);
}

where principal is a property assigned on the child's load, in order to call the objects on the parent form:

principal = (FormMain)this.MdiParent;

When i run this the first time works. The handler works until I turn visible the child form for the first time (which tells me the -= is working), removing the parent's handler. After i visible=false the child, the handler gets added back, but now it calls 2 times the event attached instead of 1, and so on with every on/off of the child (3, 4, 5)...

why? D'Oh! | :doh:

thanks a lot for your time.

Ok: the problem is with the if (this.Visible), because this will be Form1 if the child is - well - a child of Form1 and you are handling the VisibleChanged event there.

Just replace this with child.Visible or (Control)sender (I am assuming you didn't change the event-param-names for the second one.

May I ask: why doing it this way?
Just put
if (child.Visible == true) return; to the From1_KeyPressed - handler.

wow, faster than i could edit it. I accidentaly posted it before finishing it out.

No, i'm not handling the visiblechange on form1 (parent), just on the child.

this.visible actually refers to the child.

i had to do it this way because the child form has a "searcher" textbox to a "SELECT blabla like" query on the textchange to a database.

Hi.

i'm not sure if you have to do it that way, but if i have to unsubscribe eventhandlers i use to keep them as member variables in my class:

public MyForm:Form
{
    // some code here;
    private KeyPressEventHandler myHandler;
    public MyForm()
    {
        //...
        InitializeComponent();
        myHandler = new KeyPressEventHandler(Form1_KeyPressed);
        subscribe();
        //...
    }
    public void subscribe()
    {
        this.KeyPress += myHandler;
    }
    public void unsubscribe()
    {
        this.KeyPress -= myHandler;
    }
    private void Form1_KeyPressed(object sender, KeyPressEventArgs e)
    {
        // some stuff here..
    }
}

and from your MDI Child form you do simply call now the subscribe() and unsubscribe() methods.
hope this helps

Hi,

I have the code following

private void btnSelectTable_Click(object sender, EventArgs e)
{
foreach(string str in listTables.SelectedItem)
{
listSelectedTables.Items.Add(str);
}
}

I have 2 checkedlists named "listTables","listSelectedTables"

I want to remove one item from "listTables" and place it in "listSlectedTables" ,when user clicks on the button "btnSelectTable".

I guess you've got a problem with something like
listTables.Items.Remove(str)
inside your foreach-block right?

Well that's because you are trying to change the collection your are enumerating ...
whenever I need something like this I use something like

<br />
Stack<string> toDel = new Stack<string>();<br />
foreach (string str in listTables.SelectedItem)<br />
{<br />
  listSelectedTables.Items.Add(str);<br />
  toDel.Push(str);<br />
}<br />
while (toDel.Count > 0)<br />
  listTables.Items.Remove(toDel.Pop());<br />
</string></string>

"Error 1 foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'"

this is the error in the line where "foreach" is written....
I dont know what is the problem....

ah - sorry you are using ".SelectedItem" <- this will be just the one object you selected (that is a string),
try using ".SelectedItems" D'Oh! | :doh:
