• apolon_vn How-to cancel changes to a record on user request...

  Hi, I have a form where I "catch" if the user made any changes. If they try to move to another record without saving, I ask them if they want to save or not. If NOT, I would like the changed data NOT TO BE SAVED! But IT IS! Here's the code... Private Sub Check_if_record_modified(ByRef result As DialogResult, ByVal Action As String) Me.ItemsBindingSource.EndEdit() If (Me.SignsDataSet.HasChanges = True ) Then result = MessageBox.Show("Do you want to save these modifications before moving to another record ", "Warning: Data Modified.", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button3) If (result = Windows.Forms.DialogResult.Yes) Then SaveChanges ...Show All

• Shane Kirk Copy of Screen

  Good day to you. I don't know much about the ClipBoard and GetData and so forth but there seems to me that 2005 Express is not quite the same as .NET 2003. The code that I shall give in a moment gave me a full screen copy on the Form_Load event and gave a copy of the Form on a button_click event. Now, when using the code in 2005 Express the Load event only gives a copy of part of the screen. Why is this happening Is there a way in which I can rectify matters. I would be very pleased for any info. I have tried with Imports and Inherits and Paint. It is the sizing I believe.

• ray_newbie_SSIS Starting/Stopping Processes

  Hello: My scenario follows- I have a solution that contains 2 projects. Project 1 has Form A Form A has a button that starts a process, namely Project 2 Form B. Form B has a 'close' button that I want to terminate the process that was started when I clicked the 'start process' button on Form A. I hope that made sense. Basically, I want Form B to be able to close itself (using a button that I added to its form), even though it was launched (started as a process) from a button click from Form A. Thanks in advance for any help. Can accept the code in VB or C#. Hi: I'm, unfortunately, unfamiliar with Threading.

• tabdalla How do I make DirListBox select a folder and display a new list of folders with a click?

  The Windows OS on my system is setup to respond to single clicks as opposed to double clicks. The DirListBox in my app only acts when double clicked, and only selects an item when single clicked. How do I change this so the DirListBox will act like my system and the rest of my app. I have a TextBox which can handle the select (single click) action. My code for this is such a mess (at least where DirListBox is concerned) I'm going to start over, but I would like some ideas before I try again. Thanks. I was doing that, but for some reason it was not working at the time. However, once it started responding I was able find a number of bugs which I seem to have solved ...Show All

• mroctober Compare 2 objects

  hello. A question please. I do this: dim a as new person --- class person dim b as new person a.name = "Bryan" a.tel = "1111111111" b.name = "Bryan" b.tel = "1111112222" I'd want to compare the 2 objects. How can i do that Thanks... You are right, you have to do it manually, one element at a time. However, if you are using Structures instead of Classes, you can use the Equals method without defining it: Module Module1 Structure Person Public Name As String Public Tel As Integer End Structure Sub Main() Dim a As New Person Dim b As New Person a.Name = "aoeu" b.Name = "aoeu" ...Show All

• darknessangel Application - Object Browser interface.

  Alright, I must admit that I am an object browser addict. Is it a Dll that an be called by another application you can write your own Object Browser using reflection. here is a tutorial http://www.programmersheaven.com/2/Dot-Net-Reflection-Part-1 If you mean the "Object Browser" view from Visual Studio then no... that's VS stuff, not part of the framework. It doesn't even seem to be a .NET thing... It does sound like it's not something as simple as a dll to load. :( It could be that the Object Browser uses the native metadata interfaces instead of .NET reflection. Not only that probably this is faster but it also avoids actually loading the assemblies. As ...Show All

• Adminanup DEP security - Dll files fail to install - how do you program for DEP?

  How to program for the new security features in DEP My customer can not install our program in new machines due to DEP. In boot.ini there are switches that can be configured: /NOEXECUTE=OPTIN Enables DEP for core system images and those specified in the DEP configuration dialog. /NOEXECUTE=OPTOUT Enables DEP for all images except those specified in the DEP configuration dialog. /NOEXECUTE=ALWAYSON Enables DEP on all images. /NOEXECUTE=ALWAYSOFF Disables DEP.
