Hi.
I have a program that runs as a scheduled task. The program runs on XP as SYSTEM.
The idea is that the program will run in the background, while USER is active.
I need the program to logoff USER when specific conditions occur.
I tried using
[DllImport("user32.dll")]
public static extern int ExitWindowsEx(int uFlags, int dwReason);
but that appears to not log USER off.
I think maybe it's logging SYSTEM off, as it is running as SYSTEM.
How can i logogg USER?
Thanks,
SummerBulb.

You can also invoke shutdown.exe with the /l option. But I believe any logged on user gets a prompt saying that SYSTEM is trying to log off. I think is is so that any user can save his work prior to being logged off.

-Can someone help me create a setup project for an Excel add-in-
I created the add-in via VS 2010 (Visual C# -> Office -> 2010 -> Excel 2010 Add-In) and now need to create a set-up file such that when the user installs it, the add-in is automatically loaded into Excel.
This is what I tried: Creating a new Set-Up Project and adding "Project Output." That didn't work :'(
I know the add-in itself works because everytime I build it gets successfully loaded. Please help!

Hi all,
Using the Show() method of ContextMenu class ( in Windows.Forms ) it is possible to show a Context Menu. One of the arguments to the Show() method is the top left position of the Context Menu.
What I know is, instead of the top left position, the bottom left position of the Context Menu. I would like to translate this somehow to the top left position, however, neither ContextMenu nor MenuItem seem to have a Height or Size property.
Does anyone know how to fix the bottom left position of a Context Menu? Any help would be greatly appreciated. Thank you.

You could use ContextMenuStrip to create your shortcut menus. That's interchangeable with ContextMenu and has several additional properties and methods including Height and Width.

Thank you for your reply. The ContextMenuStrip has a Size property and can be used to place the Context Menu above the point I want to use.
Interestingly, the Size of the ContextMenuStrip is wrong the first time Show is called, so finally I used the method ContextMenuStrip.Show(PointToScreen(p, ToolStripDropDownDirection.AboveRight).

I'm sending mail with excel attchment and it's working fine when I run it from my local
machine. but if I try to access it from another machine it's giving me this
Error:

It looks like your target machine does not have Excel or the interop libraries installed.
It's time for a new signature.
|
|
|
|

What exactly are you doing with the Excel objects? You certainly don't need excel to send an e-mail. If you are creating or modifying the spreadsheet before you send it, is it something you could do through the ODBC driver? Don't assume that anything outside of the System namespace will be installed on a server.

Hi all,
I there any common in built class to encrypt password in java(black berry, android api) and objective c(iphone). I heard about Md5 but don't know whether it is available for all these languages.
thanks & regards

MD5 is an algorithm, so it can be implemented in any language. If it is implemented in java it should give the same results as the C# or C implementation. Don't know if it is though.
Do note that MD5 is:
1) Not an encryption algorithm. It is a hashing algorithm, which means you cannot get back to your original data from the MD5 value. For password comparison it should be ok, but not if the password is used to encrypt data or access a database, etc.
2) Not recommended for new projects, as it is officially classed as "broken". (I.e. a mechanism has been found to generate a valid input sequence from an MD5 value) Use SHA instead if you can
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Yes.
Buy this book[^]
I bought it back when it came out ... that makes me old, and it contains enough coverage to make you comfortable with encryption in the modern languages, Java and even .NET. The chat application in this book answers the annual question that we constant get on this forum of, "How do I build a chat application" as well.

Hi all,
To be precise, I have a winform (say form A) with buttons on it, which when clicked, opens up new forms (say b, c, d).
I want to set form A as the owner and forms b,c,d as owned forms of form A.
The basic thing which I am looking to achieve is that when I close form A , I want to close all other owned forms and warn the user that some forms that belong to form A are already open and if they would like to close it?
FYI - form A is already a ChildForm of a MDI parent in my application.
Any help will be appreciated.
Thanks,
|

|

Hi,
inside class FormA, instead of doing formB.Show() or formB.ShowDialog(), do formB.Show(this) or formB.ShowDialog(this).
|
|
|
|
|
thanks for your reply,
But the problem is, I want the form to be displayed within the MDI parent container.
If I use Show() or ShowDialogue() the form is displayed outside the MDI parent container.
|
|
|
|
|
then try something like this:
FormB formB = new FormB();
formB.MdiParent = this;
formB.Show();
|
|
|
|
|
Hi thanks for your reply.
Am getting this exception error when I write Ur code.
"Form that was specified to be the MdiParent for this form is not an MdiContainer.
Parameter name: value "
|
|
|
|
|
then fix the error. stuff the parent where it goes.
|
|
|
|
|
Mate,
This is the hierarchy of my app.
MDIParent > MDIChild > buttons to open additional forms.
these forms appear in the MDI Container if I set
form.MDIParent = this.MDIParent
But my question is When I close the child form, I want to close all other open forms which are opened through button clicks?
|
|
|
|
|
|
Thats the whole issue mate. If I say
Show(this) or ShowDialog(this) I get the error which says
"Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling showDialog."
Ohh I better ask Uncle Google instead.
Cheers

|

you need to set the IsMdiContainer (IIRC) property to true in the parent form.

Good Day All
I have a Method that i have defined that i will access in JavaScript(Page Method) and its defined like this
[WebMethod, System.Web.Script.Services.ScriptMethod]
public static void Getadata(String StrSearch)
{
View obj = new View();
obj.Bind_SearchBox(StrSearch);
}
And the Bind_SearchBox() method is a non static method that is defined in this code behind of this page and View is the class name of the Page. Now i debugged this and i see the results are passed to the method and the Method is Defined like this
public void Bind_SearchBox(String Search)
{
ViewerService.ViewerService obj = new ViewerService.ViewerService();
String SessionKey = obj.newSession();
DateTime Date1 = Convert.ToDateTime("1980-01-01");
DateTime Date2 = Convert.ToDateTime("2012-12-31");
ViewerService.extract extract = obj.getObjects(SessionKey, Search, Date1, false, Date2, false, "", "");
try
{
RadPanelBar1.Items.Clear();
RadScheduler1.Appointments.Clear();
int Len = extract.set.Length;
for (int i = 0; i < Len; i++)
{
ViewerService.vertex value = extract.set[i];
String PanelClass = value.meta;
PanelClass = PanelClass.Replace(Remstr, "");
PanelClass = PanelClass.Replace(Remstr2, "");
Appointment app = null;
if (value.atom != null)
{
RadPanelItem pane = RadPanelBar1.Items.FindItemByText(PanelClass);
if (pane == null)
{
RadPanelItem nwpane = new Telerik.Web.UI.RadPanelItem(PanelClass);
RadPanelItem nwpaneSpliter = new Telerik.Web.UI.RadPanelItem(PanelClass);
nwpaneSpliter.IsSeparator = true;
RadPanelBar1.Items.Add(nwpane);
pane = nwpane;
}
if (value.meta == "za.co.abacus.C_EVENT")
{
app = new Appointment();
}
int atomLen = value.atom.Length;
for (int j = 0; j < atomLen; j++)
{
ViewerService.atom atm = value.atom[j];
if (atm.meta.Contains("za.co.reactor.A_LABEL"))
{
RadPanelItem NewItem = new RadPanelItem(atm.content);
pane.Items.Add(NewItem);
if (app != null)
{
app.Subject = atm.content;
app.Description = atm.content;
app.ID = value.key;
}
}
if (app != null && atm.meta.Contains("za.co.abacus.C_EVENT"))
{
app.ID = atm.content;
}
if (app != null && atm.meta.Contains("za.co.reactor.A_HORIZON"))
{
app.Start = Convert.ToDateTime(atm.content);
}
if (app != null && atm.meta.Contains("za.co.reactor.AA_HORIZON"))
{
app.End = Convert.ToDateTime(atm.content);
}
if (app != null && atm.meta.Contains("za.co.reactor.A_TEXT"))
{
app.Description = atm.content;
}
if (app != null && app.End > app.Start)
{
RadScheduler1.DataStartField = app.Start.ToString();
RadScheduler1.DataSubjectField = app.Subject.ToString();
RadScheduler1.DataEndField = app.ToString();
RadScheduler1.DataKeyField = app.ID.ToString();
RadScheduler1.SelectedView = SchedulerViewType.MonthView;
RadScheduler1.SelectedDate = app.Start;
RadScheduler1.Visible = true;
}
}
}
}
}
catch (ApplicationException ex)
{
}
finally
{
obj.closeSession(SessionKey);
}
}
Now this Function works well and it has no problems , in the debug more, i check the value that is supplied to this function from the page method function its fine. and my JS looks like this
function keyPress() {
var tb = document.getElementById("<%=txtsearchid%>");
if (tb.value.length == 2) {
PageMethods.Getadata(tb.value);
ToggleCollapsePane();
}
return false;
}
and the Toggle function
function ToggleCollapsePane() {
var splitter = $find("RadSplitter1");
var pane = splitter.getPaneById("LeftPane");
if (!pane) return;
if (pane.get_collapsed()) {
pane.expand();
}
else {
pane.collapse();
}
}
so the Getadata() Function will call the Bind_SearchBox() Function and pass the Parameter and the function Bind_SearchBox() will do the Job as you can see at the end it sets some control to visible. But this does not bring me back results(The RadScheduler1 is not binded with data and RadPanelBar1 does not show anything)
I had a search button that is that was calling the same method and passing the same parameters but it could show results and it looked like this
protected void btnSearch_Click(object sender, EventArgs e)
{
RadToolBarItem textItem = RadToolBar1.FindItemByText("Button1");
TextBox txtseach = (TextBox)textItem.FindControl("txtsearch");
if (txtseach.Text != "")
{
Bind_SearchBox(txtseach.Text.Trim());
}
}
In FireFox i get this Error when i debug it
<br />
Microsoft JScript runtime error: Sys.Net.WebServiceFailedException: The server method 'Getadata' failed with the following error: System.NullReferenceException-- Object reference not set to an instance of an object.
If i click this above button it will show results. The txtseach have the same text and it calls the same method but when i call this function and inject parameters from page method it does not work.
I am Surprised.
Thanks

First of all this is the question for ASP.NET forum.
Second: it's no surprise that it doesn't work really. What you're trying to do must be accomplished with a postback. You can call your Bind_SearchBox from JavaScript, but Bind_SearchBox will have no way to return its results to the browser. Solution for your problem is to execute postback instead of calling pagemethod. I don't remember parameters exactly, but you have to supply it with id of control, that triggers postback (in your problem this would be a search button). Or maybe you should reconsider your solution and trigger the Bind_SearchBox from additional postback.
I hope, that what I written is more less clear. If not, please ask
