private bool switchMC=true;
private void mButton(object sender, System.EventArgs e)
{
Button btn = null;
if(switchMC==true)
{
btn=(Button)sender;
btn.Text="1";
switchMC=false;
}
else if(switchMC==false)
{
btn=(Button)sender;
btn.Text="0";
switchMC=true;
}
}
I'm not sure if I'm giving enough information here...
When I run this, it takes 2 clicks to get the else if statment to run...
How can I get it to 1?

Hmmmm, just remove the "else"?

Your code works fine here, on loading the button text is whatever is has been set to in the designer, on the first click the text changes to "1", then next click it changes to "0", then to "1" and so on and so forth..
I'm not sure what it is you want to achieve, but if you wanted the button text to be "1" before clicking it, you would need to invoke your button click event handler somewhere beforehand, for example:
mButton(this.button1, null);

Sorry, I didn't explain enough...
There are 7 different buttons that use that method.
They all start out at 0.
Now, try the code out and see what it does... It's rather hard to explain...

Well, the thing is...
try it with 7 diffent buttons which all use mButton for their on_click...
It get's weird results... just try it out real fast...

Is your btn.Text initailly set to "1"? You have the initial value of switchMC as true, so the first time through it will go through the "True" condition and the next time it will go through the "False" condition.
Also, you do not need the second "IF" since you are using an ELSE, the ELSE will only be reached if switchMC is not true so you do not need the addition test. You could also restructure the code to either:
Button btn = (Button) sender;
if(switchMC)
{
btn.Text="1";
switchMC=false;
}
else
{
btn.Text="0";
switchMC=true;
}
Or
Button btn = (Button) sender;
btn.Text = switchMC ? "1" : "0";
switchMC=!switchMC;

What is the result your are looking for? You have one state flag which toggles to true or false. Don't you want an array of state flags so you have one for each button?
If that is the result you want (the state of the clicked button to toggle, then you would want to check if the btn.Text = "0" and if so then change it to a "1" and visa-versa:
Button btn = (Button) sender;
btn.Text = btn.Text=="0" ? "1" : "0";

There is an Array.Sort() function that sort one dimensional array. How can I sort two dimensional based one of dimensions?
Mazy
No sig. available now.

yeah extend the class and write your own algorithm for it. Arrays in .NET suck, they should have grabbed some more java ideas

How can I get the KeyDown event to fire for the arrow keys?
|
|
|
|

you have to override the IsInputKey method, so that it returns true with the key arrows.
protected override bool IsInputKey(Keys key)
{
if (key.KeyCode == Keys.Up) return true;
else if (key.KeyCode == Keys.Down) return true;
else if (key.KeyCode == Keys.Left) return true;
else if (key.KeyCode == Keys.Right) return true;
else return base.IsInputKey(key);
}

I tried that, but when I put a breakpoint there, I see the function never gets called... hmm?
|
|
|
|
|
hmmm, it should do, it does when i create controls, are you creating a control from scratch? or adapting a current one?

To override the form or custom controls
<br />
protected override bool ProcessKeyPreview( ref System.Windows.Forms.Message mes )<br />
{<br />
Keys keyCode = (Keys)(int)mes.WParam & Keys.KeyCode; <br />
<br />
if((mes.Msg == WM_KEYDOWN || mes.Msg == WM_KEYUP) && keyCode == Keys.Down ) <br />
{<br />
MessageBox.Show("Arrow handled");<br />
return true;<br />
}<br />
else<br />
return false; <br />
<br />
}<br />
for other controls like a textbox
<br />
Form1_Load()<br />
this.myControl.KeyDown += new KeyEventHandler(this.MyKeyDownEvent);<br />
<br />
<br />
...<br />
<br />
<br />
private void MyKeyDownEvent( object sender, KeyEventArgs e )<br />
{<br />
if ( e.KeyCode == Keys.A )<br />
MessageBox.SHow("Hey you typed an AS");<br />
}<br />
there you go dude the above works for override the message loop for custom controls and the below works for controls inside your container.

Downt forget the defines, I dont know where they exist in c# so i just make them consts
private const int WM_KEYDOWN 0x100;
private const int WM_KEYUP 0x101;
your C++ include files have all the values inside the libraries.

Hello,
I have two tables, I wish to display the child table on the datagrid.. and a specific column from the parent table.. For example |column1|parentcolumn3|column2|
The child table is related to the parent table via parentID, but this is not the parent column I wish to display..it is parenteColumnXX
Can this be done on a dataGrid?? I do not want for the parent table to be displayed as a link neither I just want one specific parent column to be displayed in the same datagrid as the child table..
Hopefully I manage to explain the situation correctly..
And as always I really appreciate any help offered!!
Thank you!

why sure you could but you will need to create either a view to maintain this or extend the grids functionality for data binding. I would try the first, first.
You will need to create your own tablestyles collection

The error:
The action being performed on this control is being called from the wrong thread. You must marshal to the correct thread using Control.Invoke or Control.BeginInvoke to perform this action.
Begin the delegate call:
<br />
private void Form_QueryOperation_Load(object sender, System.EventArgs e)<br />
{<br />
<br />
SampleSyncronized sampSyncObj = new SampleSyncronized();<br />
SampSyncSqrDelegate sampleDelegate = new SampSyncSqrDelegate(sampSyncObj.LoadTreeView);<br />
IAsyncResult aResult = sampleDelegate.BeginInvoke(tvOperation, null, null);<br />
<br />
aResult.AsyncWaitHandle.WaitOne();<br />
<br />
sampleDelegate.EndInvoke(aResult);<br />
<br />
<br />
}<br />
Updating class
<br />
[Synchronization()]<br />
public class SampleSyncronized : ContextBoundObject<br />
{<br />
public void LoadTreeView( System.Windows.Forms.TreeView crossTV )<br />
{<br />
LoadTreeViewNow(crossTV);<br />
}<br />
<br />
private void LoadTreeViewNow(System.Windows.Forms.TreeView tv)<br />
{<br />
<br />
add tree node codew here<br />
how do I catch the current main thread to update the trre view
