Mobiles :: Close All Form And Terminate App In .net CF?
Apr 1, 2011
I've been searching for a while for a solution to accomplish above subject, I have a win app for handhelds in which the user can navigate through several windows forms form.showdialog() The question is how to close all windows and terminate the app when user press exit button.
process.getcurrentprocess().kill(); --> didn't work Foreach (Form frm in Application.OpenForms) --> doesn't work in .net Compact Framework frm.Close();
I mean if I use form.show() to open the windows, it works with Application.Exit();, but I want to prevent the user navigate away from the current form thru the icon for open windows on the right lower corner of the handheld, unless he press the close button of the form, that's why I use form.showdialog(), the other approach could be to show only the current open form of the application if the user press the icon for the open windows on the right lower corner.
In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.
i made a web application and i need it to work on a windows mobile system, the thing is that some control don't work the way i planned one thing is that form authentication doesn't work i have two question,

2- i need a way to print from this device (HTC TyTN II) to a bluethoot device (DPP-250).
I am trying to display a local .html file in a web page. The file uses javascript to display some information about my phone. In the executable, I am retrieving two values out of the registry. I would like to pass these values in a query string (I think that is the correct terminology). Something like file://\Program Files\TestTest.html?type=newtype. I have attempted this with using webbrowser.navigate, but that is giving an unhandled exception when it tries to pass the URI string. Obviously, I have no experience with this and am using the wrong method. There has to be a simple way to open a new webpage in a form and pass it this type of string.
how to implement such a function? I have been attempting to implement this with Visual C# using the .net CF for Windows Mobile.
I am debugging an ASP.Net C# application in Visual Studio 2010, the application is running and execution is currently stopped at a breakpoint. How can I stop the page execution without "Terminate All" or killing the debugging process altogether, similar to what would happen if an unhandled exception was thrown? The "Break All Cntl+Alt+Break" option is grayed out in the Debug menu.
I want to stop the app from running but not have to go through a compile/start again. EDIT: I want execution to stop, not break, so that the page finishes loading and I don't continue running the application from the breakpoint forward. I've looked through the Breakpoints panel, the Debug menu and have right clicked all over but still haven't found the right option.
I have website which runs multiple threads. When user close the browser but threads are still running. How to kill/stop all thread in asp.net on browser close.

wanted to know what is the easiest way to interface a mobile phone device with an online system. I have literally NO knowledge in this domain. However, I am brainstorming on possibility of an online application that will allow me to backup my data in nokia set 3110 such as my Address book in the application and restore it. This I want to achieve without connecting my phone to any PC. I am thinking on some way to achieve this by leveraging mobile phone line only. I beleive it may require my application to connect to mobile phone through mobile phone network. Currently my mobile phone line subscriber is offering Address Book backup/ restore service with some charge. I want to see if I can replicate similar features. I would really appreciate if you can give a direction to my random thoughts.If anything is not clear then please feel free to inquire. I look forward to your kind response.
In order to terminate a SQL Server query within a VB application, we use the Dispose method to close and dispose the database connection. That has been the only way we have found to actually stop a query from running and release the resources.
However, the next time a new connection is created to the same database, we are getting the error "'ObjectDisposedException - Safe Handle has been closed.". It seems like it is always trying to reuse the disposed connection from the connection pool, and it is not reinitializing it. By using a different connection string, we can avoid the error, since now it's not using the connection pool. But there must be a better way to either stop the query or to reinitialize the disposed connection.
I am using this code.This pop up window pops up when I clicks a button on the main page.Now I want the pop up window to be closed if the password is successfully changed and reload the main page,but if the password is not changed then refresh the pop up window again.
i would like to know if there's something wrong in this asp.net code:
mydatareader = mycmd.executeReader() if myDataReader.HasRow then // Do something end if myConnection.Close()
If i avoid to call a "MyDataReader.Close()" does the connection close anyway ? I ask this because i'm assuming that if call a "MyConn.Close" it automatically close the associated datareader... or am i wrong ?
I have a page where I load a couple of dropdown lists from the database (DB). I do this by calling a general function that connects to the DB and gets the data to the dropdownlist. This means that I can have three queries to the DB while rendering one page.
should I close and dispose the sqlconnection, sqlcommand and sqldatareader at the end of this function?
Would it be faster if I left it open for the next call, if you get what I mean, or is it best to close and dispose it every time?
I am having trouble closing jQuery Facebox from code behind. I am inserting a new record through FaceBox, on successful insertion the FaceBox needs to be closed. How can i achieve this?

I am Opening a Page as a Popup i am using Telerik WIndow which has similar functionality when opening a Popup like this
Code:
function OpenPopUp(val_real, vis) { var myWidth = 0, myHeight = 0; if (typeof (window.innerWidth) == 'number') { //Non-IE myWidth = window.innerWidth; myHeight = window.innerHeight;
[code].....
this "myPage.aspx" page has a button that person some updates to the Database on the server side. This is opened as a popup and there is a grid below , so what i want to do after the Update to the Database has happened , i want to refresh the Grid, i have this code
Code: //This code is used to provide a reference to the radwindow "wrapper" function GetRadWindow() { var oWindow = null; if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz az well) return oWindow;
My problem here is that it Refresh the page before it does a Database Update, and if it refreshes the page , the Database update ends up not being done.
I have a mobile selection list (see blow) that I had programmatically filled in from a generic collection of Status object (see below) which was retrieved from the database since I wanted to use the ID and Value stored in there to the selection list.
Mobile SelectionList Sample
[Code]....
Status Object model
[Code]....
Filled in a generic collection of Status object
[Code]....
Then, I tried to fill in the mobile selection list control using:
[Code]....
Now, when I tried to get the value of the selection list... it is giving me the same value as to what was stored in the text of the selection list. I tried using the following snippet:
[Code]....
or
[Code]....
Is there anyway I can get the value of the selection list that was retrieved from the database instead of the indexes?
