BindingNavigatorAddNewItem - Default Value Is NOT WRITTEN To The Table
Jan 1, 2011I have a question about the AddNewItem method. From what I understand, then this event occurs, the EndEdit() method is called and a new record is created IN MEMORY (or a buffer). The user fills in the form that is presented and when the Save button is pressed, the record in the buffer is actually added to the table.
In my application, a form is displayed and some of the forms databound text boxes have DEFAULT values (see the property for the textbox under the Data Bindings, Advanced and NULL VALUE). For example, I have a text box that holds a number and the NULL value is set to 0. When the form displays, the ZERO is in the text box. Assume the user NEVER enters the field or changes the ZERO to something else (which means the field is never validated).
Here is the problem. When the SAVE button is pressed, the ZERO that was the default value is NOT WRITTEN to the table. The field in the table is DBNULL. That is not the desired outcome. So - How can I check the fields in the BUFFER BEFORE they are written to the table?

View 2 RepliesGet The 'Progress' Dialog To Display Immediately After The 'Install Icon' Dialog Disappears?
Jun 4, 2009I have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?

View 3 RepliesPassing Information Between Forms/dialogs (Form -> Dialog -> Dialog)?
Dec 22, 2009I often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.
How To Use A File Opener Dialog And A Folder Browser Dialog
Jan 27, 2010I have an assignment due this week in which I have to make a app that has 5 buttons and a picture box. When each button is clicked it has to show the corresponding picture in the picture box, the fifth button closes the app.
I have the whole form set up the way it should be, but I have no idea how to write the code to make the buttons display the images and close the app.I have the images in a folder within the project folders.
I have yet to be able to find one, the one I found should how to do it using a file opener dialog and a folder browser dialog but that is not what I think my prof wants us to do, as that is more for a picture viewer app that lets the user choose the file of the image they want ot view.
All i want is for the buttons to be linked to specific photos that are part of the application itself and have them open.
