You see the code of StartConnect. I think and hence wanted to add StartConnect() in a thread and catch exceptions like that, but it didn't work out.
Is it better to handle it in thread (the code that's commented) or as I have dneo is correct. If the commented is correct, then how to trap exceptions that are thrown by StartConnect or not to throw exceptions and handle them in that method only.
Please guide me for this also. I am on this issue from last 3 days, on many trials couldn't suceed. Your points are helping to suceed. Thanks a lot. I highly appreciate it. Please keep helping on this issue and help me run the code normally to its and yours best.
Thanks & Regards,

From looking briefly at your code, I think you first need to read up on threads before you try moving the code: you don't seem to understand what you are trying to do and the effects it has on execution.
Read up first, and get your head round it. Then try it, and if you have problems, post a new question!

Truly telling I read Threading tutorials of C#, but not getting such ways of threading. I mean calling method in it and such.
I get threading of Java & C++ nicely, but C# can't get in mind properly. 
If StartConnect is in a Thread, it cannot throw exceptions. If adding such type of code in a thread is best practice, then how to accomplish such activity as I have done. If I am wrong in my this thought, please tell me.
Without putting in thread (the current situation), its working proper & also showing exception of cannot find file only. Thanks a lot for this. Please if you can help with the above also would be great. Atleast guide, I am not asking for written code. As said, this type of threading doesn't fit proeprly in my mind, so need assistance.
Thanks & Regards,

Thank you.
I created my Report and i can see it at run time, But for printing, everytime user should open printer settings and change the paper size.
i want to set paper size at design time and print the report programmatically.
I wrote below code (doesnt work):
this.reportViewer1.PrinterSettings.DefaultPageSettings.PaperSize.Height = 1169;
this.reportViewer1.PrinterSettings.DefaultPageSettings.PaperSize.Kind = PaperKind.A4Extra;
this.reportViewer1.RefreshReport();
Also i couldn't find PrintReport option for ReportViewer.

Hi Experts,
there is a control derived from System.Windows.Forms.Panel that I can drop things on. The panel shows a representation of what was dropped onto it. Further, I can drag things around on that panel, moving the representation in the process.
Now I have to change that behaviour in such a way, that representations get created OnDragEnter. Customers shall move things around without having to drop them and grab them again.
Now my problem is that OnMouseMove doesn't fire during drag'n'drop operation. Therefore, panel creates a representation OnDragEnter, but refuses to move it around until user releases the left mouse button.
Does anyone know of a solution for that problem?
Can I abort a drag'n'drop operation (there's no drgevent.Cancel)?
Ciao,
luker

Would this[^] help with the drag image?
There's a DragAction.Cancel property. Any good?

Since DragAction.Cancel belongs to
protected void OnQueryContinueDrag(QueryContinueDragEventArgs e), which is overridable, I can at this point find out, wheter to continue the drag operation and this works as expected.
Thanks a lot.

Not exactly sure what you mean by this, but, it sounds like perhaps you should use a TemplateColumn and adjust the button controls as required.

Handle the RowDataBound or RowCreated event and update the button text appropriately.

i couldnt find both events that u suggested...i have UserAddedRows and RowsAdded..i tried both
private void datagridview1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
datagridview1.CurrentRow.Cells[6].Value = "Insert";
}
i cant catch Text Property here..that is why i used Value property but it gives error like "Object reference not set to an instance of an object."
so what else i can try ?

this is my code
private void Form2_keydown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Up)
{
You.Location.X = +1;
}
}
and this is my error
You.Location.X = +1;
can some one plz help me, because that code makes sense to me, what did i do wrong, the thing im trying to move is a picturebox

You cannot change the Location. It´s readonly. You can use the Left or Top property (I never know what X/Y is ...)
I cannot remember: What did I before google?
|
|
|
|
|
Shouldn't this be You.Location.X += 1;? BTW, you haven't actually shown what your error is, you've just shown where it is.

You can't change the values of a Point: they are read only.
Create a new point instead:
private void Form2_keydown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Up)
{
You.Location = new Point(You.Location.X + 1, You.Location.Y);
}
}

The online help for the Location property describes the behaviour and how to resolve your problem.
Control.Location Property "Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. To adjust these properties set each property value individually, or set the Location property with a new Point."
You.Location.X = new Point(You.Location.X +1, You.Location.Y);
Architecture is extensible, code is minimal.

Assuming You is a Control:
You.Left++;
