me using following query to fill dropdown
"select CountryName, CountryID from CountryTable"

but before that
i want to clearify

DropDown1.Items.Clear()
ListItem _Item = new ListItem("-Select Country-",0)
DropDown1.Items.Insert(_Item, 0)
DropDown2.Items.Clear()
ListItem _Item = new ListItem("-Select City-",0)
DropDown2.Items.Insert(_Item, 0)
DropDown3.Items.Clear()
ListItem _Item = new ListItem("-Select Location-",0)
DropDown3.Items.Insert(_Item, 0)
when i change selection of Country drop down

DropDown2.Items.Clear()
ListItem _Item = new ListItem("-Select City-",0)
DropDown2.Items.Insert(_Item, 0)
DropDown3.Items.Clear()

hello,
im looking for a solution with a slight problem that im sure it is possible, but i cant find anything about it on the web.
In my code, im calling a leave event out of a control that check's if the control has made any changes (txtBox, combo Box...) raising a question telling the user that changes weren't saved.
if the user click's on Cancel button, i want him to stay in the control and not actually leave like he initially did.
How can i do it ?
Thanks
private void TabControlChars_Leave(object sender, EventArgs e)
{
DataTable charChanges = null;
if (charsTypeDT != null)
{
charChanges = charsTypeDT.GetChanges();
}
else if (charsDT != null)
{
charChanges = charsDT.GetChanges();
}
if (charChanges != null)
{
DialogResult result;
result = MessageBox.Show("Changes were made without saving !!\n"
+ "All Changes will be lost ...", "Warning", MessageBoxButtons.OKCancel, MessageBoxIcon.Warning);
if (result == DialogResult.Cancel)
{
???
}
}
}

Try setting focus back to the textbox.
You can also place the code in the Validating event and then use Cancel property of the CancelEventArgs there to remain in the textbox.

Your logic should ideally be placed in Cancel button's Click event.
|
|
|
|
|
Sorry, but i didnt get you..
the message Box is created inside the Leave event so how can i put the event in the cancel button click event ?
|
|
|
|
|
I'm sorry, I got your question wrong.
In your case, instead of using the Leave event, use the Validating event and if the user chooses cancel, set e.Cancel = true (e is the ValidatingEventArgs passed to the method).

What is the source of data that you are showing in gridview ? Read those data and put into the database. Or your problem is something else ?

any recommendations are strongly appreciated

What is the error you are getting?
|

|
|

Not without seeing your code and getting an explanation of the problem you're having.

sorry for unclear explanation of my problem.
the code that I have try is below:
delegateGetInputReportData getInputReportDelegate = null;
getInputReportDelegate = new delegateGetInputReportData(myAccessForm);
base.Invoke(getInputReportDelegate,/*args*/value);
a new delegate method is created on each data receive event.
in myccessForm I try
TextWriter tx = new StreamWriter("Data.txt");
tx.WriteLine(index +" " + s1.ToString() + "0" + s2.ToString() + "\t\t" + str + "\t\t" + p.ToString());
but it causes an exception that file is used by another program I tried to solve problem by using mutex but It does not work.

Dear Sirs,
I searched online and the forums and can't find the answer to my question. I would like my program to hide its console window in a managed way, but only AFTER allowing the program to output there. Basically, it goes like this:
public .ctor()
{
_Init();
_Open_SS();
System.Console.Hide();
}
So, if anyone knows how to do this in a MANAGED-ONLY context (I don't want to use DllImport("Kernel32.dll")]extern int FreeConsole(); ). Thanks in advance for your help!!
In Christ,

I know you said Managed code, however I don't see any way of avoiding it as the console is an unmanaged host for the application output. However I would recommend
[DllImport("user32.dll")]static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
rather than FreeConsole as you don't really want to detach the process from the console, just hide the console. Well, having said that, maybe you do, but I wouldn't.
If you have knowledge, let others light their candles at it.
