Then you must have some other errors in your code.
The DialogResult property of your Button just determines the value of your Form's DialogResult property when the button is pressed.
At the end of your button event handler, the dialog is closed if the Form's DialogResult property is not DialogResult.None, simple as that.
If you don't want the dialog to close you have to set it's DialogResult to DialogResult.None.
So in my example, the call to this.Close(); is superfluous, but I wanted to show you where the dialog gets closed.

U can overcome this by many ways
firstly make checks in the main form after the dialog result returned OK and if the validity check fails showdialog the input form again
otherwise to keep the main form free from the validity check mechanism
check in the button click event ... since a modal dialog is not destroyed until disposed raise a flag that says "Wrong INput" and let main form check this flag and show the main form again .....
or set the dialog result for the form and the button to none and set the dialogresult for the form in the event if the check is alright so that clicking the button doesnt close the form but u do programitically when reqd and that the main for sees only the dialog result for the form .. take a look at this

Tier Developer uses it's own project have extension named *.tdvp. This file type can be understood by .NET and they work well with each other.
My question is: how to do this? How to write an aplication that can be embed to .NET environment?

I'm trying to do logarithmic curve fitting to plotted data points.
The equation is as follows:
y = a + b*ln(x)
The problem is that I have no clue how to compute the 'a' and 'b' coefficients.
Can anyone think back to scientific comp to remember how this is done?
Thanks
|
|
|
|
|
let u=ln(x)
then y = a + b*u
now use the method of least squares to find a and b.
Note: you are using the method of least squares to find y(u), so everywhere you would use x in least squares now use u(=ln(x)).
There are several good resources on the web. Google for 'Least squares' and 'logarithm'.

Hi, I'm working on a syntax-coloring textbox that inherits the RTB control and I have an annoying problem. Since I'm using Select method / SelectionColor property to highlight syntax, I must always store the current cursor position in a variable and then restore it by calling the Select method like this: this.Select(CursorPosition, 0). However, a problem occurs when contents of the textbox spread over more than one page. Namely, the call I use always causes the control to redraw in such manner that the line where CursorPosition is located becomes the first line of the visible area of the textbox, effectively shifting the visible area of the textbox a number of rows down. For example:
Pic 1
Pic 2
It is very disorienting, but I have no idea how to stop it from occuring. Is there some API call or something that can position the cursor within the control without causing this stupid change of focus? If anyone can offer me a way around the problem I will be most grateful.

How could I change the data source of a dataGrid in run time (Windows Forms)?
datagrid.Update()
What I am trying to do is, to change the data source of the data grid with respect to CustomerID..
If customerID is changed, than the dataView will retrieve the data from DataSet table and then update the datagrid ,without changing data source , update data source with DataView But I couldnt find the method, please guide me to achieve.
Is it possible ?
Thanks ,

Hi,
Why to change the datasource? Instead that we can associate the Dataview to the datagrid. Filter the DataSet into Dataview using RowFilter and RowStateFilter properties of Dataview.
Dataview.RowFilter = "customerID=xxxx";
Thanks

thanks for the reply ,
but my problem is to update the datagrid.
I can not update the dataGrid when I change the dataView.
To be more specific
I have a curreny manager which is holding the information about the customers named cm
I have 2 dataTables dt_Orders and dt_Customers for orders and customers
I inserted the update operation into ShowCurrentRecord which is called when CurrenyManager_PositionChanged event..
<code>
private void cm_PositionChanged(object sender, EventArgs e)
{
ShowCurrentRecord();
}
private void ShowCurrentRecord()
{
string CustomerID=ds_Customers.Tables["dt_Customers"].Rows[cm.Position]["CustomerID"].ToString();
for(int i =0 ;i <RowCount ;i++)
{
<p>if ( ds_Customers.Tables["dt_Orders"].Rows[i]["CustomerID"].ToString()==CustomerID )
{<p>myDataView.RowFilter="CustomerID="+CustomerID;</p>
</code>
It turned out to be , I can not set anything into RowFilter..
even if I tried dv.RowFilter="CustomerID"+CustomerID;
dv.AllowEdit();
dv.BeginInit();
When I use Watch the find the value , although CustomerID has its value , watch always shows RowFilter as null string..
Does dataView can be edited in run-time ?
|
|
|
|
|
Hahahah , the whole problem was myDataView.RowFilter = "CustomerID= '"+CustomerID+"'"; : )
|
|
|
|

Ok. Guess your problem is solved now

Theres one more thing I have to bug you guys with.
ATM, I am exporting my Bitmap object to a JPEG file, which works quite well.
But I would like to have that Bitmap object/JPEG file appearing on an excelsheet ... exporting a datagrid to a specific sheet already works, so I only need to know the command for exporting the image ...
Any help greatly appreciated!
