It looks like this :
if (this is true
{
MessageBox.Show("blah blah");
}
else
{
// none of this code is called, I've stepped through to see this is the case.
}
I changed it to this to ensure the other code is never called, and I've stepped through to see for myself.

Thanks - it makes no sense to me at all. I understand how to assign a button to close a dialog, and I've simply not done so. All I can think is that I did set that up early on, and some remnant of that fact is lurking beyond my reach ( in that the properties tell me it's not set ).

Have you manually checked the designer-generated code? I had a case last week in vb.net where the handler got wired up wrong. I couldn't figure it out because when I used the VS editor interface, it took me to the routine I was expecting, but in the designer code, it was also wired up to another handler. As soon as I fixed that, the code I was expecting was getting called.

Good call - I'll give it a look tonight. I was going to just delete all the buttons and create new ones, and see if that helps.

Please see documentation for Button.DialogResult property in MSDN. It is mentioned that:
If the value of this property is set to anything other than DialogResult.None, and if the parent form was displayed through the ShowDialog method, clicking the button closes the parent form without your having to hook up any events. The form's DialogResult property is then set to the DialogResult of the button when the button is clicked.
Therefore, it is clear that for the button labeled “OK” in your dialog box, while the Text property could be set to “OK” string, but if the “DialogResult” property of this button is also set to “OK”, then clicking this button will automatically close the parent dialog box without your having to hook up any events.
So, the solution to your problem is that you must NOT set the DialogResult property of the OK button (say btnOK) to “OK”, while the Text property of this button might still continue to be “OK” to keep it visible as such to the user. You may set the DialogResult property of this button to “None”. Now, in the click handler of the said OK button, you can do your processing as desired. But please remember to close the form yourself in the code as per your scheme.
I may also mention that as per the documentation, the AcceptButton/CancelButton properties are irrelevant for this purpose because they are useful to allow "Enter" or "Escape" keys instead of the mouse-clicks on OK and Cancel buttons respectively. What is of relevance here is that DialogResult property which can have a possible of 8 values (i.e., Abort, Cancel, Ignore, No, None, OK, Retry, Yes).
I have tested this in my test application by setting and removing the DialogResult property of the OK in this manner, and it ran alright. Hope it solves your problem as well.

Hmmm - thanks for all this, it obviously explains one problem ( the double close behaviour ), although I'm surprised to hear that the buttons could be set this way, as I set them to none explicitly. This could be an indicator that the resx file is in a mess.
And if the resx file is screwed, that would explain the other behaviour as well.

I am not sure that i understand what you mean.

//I want to draw an X-Y coordinate system on a WinForm (400, 400). The only code I entered after cteating the Form is beween the comments. It doesn't lookk centered. Why? --thanks
static void Main()
{
Application.Run(new Form1());
}
PROBLEM IS HERE->//////////////////////////////////////////////////////////
private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g = e.Graphics;
Pen myPen = new Pen(Color.Black, 1);
Rectangle rect = new Rectangle();
g.DrawLine(myPen, this.Width/2, 0, this.Width/2, this.Height);
g.DrawLine(myPen, 0, this.Height/2, this.Width, this.Height/2);
}
//////////////////////////////////////////////////////////////

Replace
g.DrawLine(myPen, 0, this.Height/2, this.Width, this.Height/2);
with
g.DrawLine(myPen, 0, this.ClientSize.Height/2, this.Width, this.ClientSize.Height/2);
this.Height probably includes the height of the menubar and titlebar also, that's why it didn't look centered.

this.Heigth is the height of the window including any NC (Non Client) stuff (title bar, borders, scrollbars etc.)
Use the Control.ClientRect to get access to the actual size of the content area of a window.
<code>g.DrawLine(myPen, this.ClientRectangle.Width/2, 0, this.ClientRectangle.Width/2, this.ClientRectangle.Height);
g.DrawLine(myPen, 0, this.ClientRectangle.Height/2, this.ClientRectangle.Width, this.ClientRectangle.Height/2);

hello,
we use to log a lot of data a compact flash datalogger. I want to read out the cf-cards by copying all files to a new directory an delete the cf-card, so it can be reused.
My problem is now, how do i recognize in a c#-program, that there is a new cf-card. I think i need the information, what new drive name (e:, f:, g:...) the new inserted card has and then i have to copy the information to the disk.
Any hints may be usefull (also with other programming languages, if there is an other one more appropriate).
Thanks in advance,
Heiko.

your probably going to have to import a native library to do this, best thing to do is to search google and hope some one has already incapsulate this functionality
just like cd burning the .NET framework does not directly support this, you might be able to find the COM DLL on your own, but you would probably be hard pressed
sorry i can't help you more but your best bet is google for "cf-cards" and "C#"

hi everybody
anybody knows how can i save drop down box items in a text file?
thank you
|
|
|
|

Try something like this:
using (System.IO.StreamWriter sw = new System.IO.StreamWriter("test.txt",false))
{
foreach(object o in this.comboBox1.Items)
{
sw.WriteLine(o.ToString());
}
sw.Close();
}

The sw.Close call is redundant, the "using" statement automatically closes the StreamWriter when control reaches the end of the block.

Yup, I know this is true for the StreamWriter (and should be for any class implementing the IDisposable interface).
I just can't get rid of the habit to be on the safe side.
And sometimes i have something like this:
using (x)
{
using(x.y)
{
x.Close();
}
}
by calling the x.Close i simply free the resource as soon as i do no longer need it, not as soon as the finally of the using statement is reached.
And finally you never know if the IDisposable.Dispose actually does implement all the stuff you expect it to contain.
OK, your are right... it is redundant  (but i still have my points!)

Hmm. Just for the sake of argument,
using (x)
{
using(x.y)
{
x.Close();
}
}
After all, that's the sole purpose of the using statement

Senthil

hi
can anybody help me to see if a certain item exists in a drop down box?
thank you
|
|
|
|

Use the Contains function on the drop down box's Items property. Like
...
bool isItemPresent = comboBox.Items.Contains(itemToBeFound);

Which one? It would be easier to help if you said what exactly that error says. (with stack trace if possible!)

You don't. If your drpSelected.Items contains array of string, than it works. If it does not, item text (displayed in control) are result of item's ToString() method. Now think about it. What Contains method need to find your item? It must be able to say if some item from items is (equals) to item you are searching for. So, in order to make THIS example work, you can a) have only strings in drpSelected.Items (so Contains will compare string references) or b) override Equals() method for items or c) if( drpSelected.Items.Contains( item ) ). First option seems to be best, but then again we have no idea what your code *really* means.
[edit]
or you can create new item (e.g if( drpSelected.Items.Contains( new item(lblID.Text) ) ) )+ override Equals(). But that sounds quite stupid
hmmm it looks like your drop has something to do with IDs? I suspect your Item have properties Item.UserName and Item.ID, right? Don't you need only selected one? Than use SelectedValue instead of SelectedText. (you must fors say what is Value "column" -ListControl.DataValueField Property[^] )
[/edit]
Does it help?
