I've developed a small windows form application in Visual Studio 2005. I have tested the application on a completely fresh install of Vista 32-bit as well as Vista 64-bit and it works fine... But when I copy the application onto an XP machine the following problems occur:The application no longer has its icon, just the default .exe console box icon
Whenever I try to open the application, absolutely nothing happens

Visual Studio 2005 SP1cr10 developer also installedOn XP machine, works fine. Got a Windows 7 machine(64bit and all) and copy over the project, run it and can't, I get an error in each crystal report gets an error [code]I take these lines out, and no more error for the report. Since there are like 40 reports in a project and there's 5 different projects that would have to be altered, this will be a pain. And I'm not the only developer. Another developer, on Vista and another will be coming in on XP, don't have this issue. I've tried uninstalling everything Cr and visual studio, then reinstalled visual studio and ran it, same thing, then installed SP1, same thing, then updated security fixes, same thing. CR10 isn't installed. I've removed and added the references back ,they seem to be the exact same versions.
View 3 RepliesI have a test app driven by bluetooth serial events In my form load code I hide the cursor so it doesn't get in the way of pictures (fullscreen) When one event is called by bluetooth, it brings up a msgbox and the user has to click OK. I tried Windows.Forms.Cursor.Show() but it doesn't work.
I'm guessing it's something to do with delegates and events and the form, but the debugger doesn't complain at any point. It just refuses to show the cursor. How can I get my serialport event to show the cursor? And then hide it after?

I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.

I am launching an external that brings up a window that is split into two frames. I am able to get the handle of the frame and what I want to do is click inside the frame in a certain area.
For example, if I open "System Information" by launching msinfo32.exe, how would I click on Internet Settings in the left window pane? I don't need the exact coordinates, just an explanation of how it can be done using SendMessage or PostMessage.
I've tried things like:
PostMessage(sideWnd, WM_LBUTTONDOWN, 200, 1200)
PostMessage(sideWnd, WM_LBUTTONUP, 200, 1200)
I wasn't sure if the end two numbers would be coordinates, but if they are, I've tried different numbers and can't seem to get it to click anything other than the first item in the list of the left window frame.
Excuse me for posting this, but I have searched both Google along with this forum before asking this question, maybe I'm not using the right keywords but I apologize if it's easy to find.I would like to know how one could close a third-party window (application) if a specified string was found in the window title.

View 4 RepliesI have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.

I'm setting up a simple XML read-write demo (VB Winforms) in Visual Studio 2010 Premium (tried in both the RC and RTM) and added:
Imports System.Xml
Result: Error Namespace or type doesn't contain any public members or cannot be found...
VS 2008 equivalent example recognizes the Imports statement fine.I know this has to be me, but I'm stumped.
Note: I tried this with the app targeting both .Net 3.5 and 4.0. Same result.
I have a WPF VB.NET project in Visual Studio 2008. For some reason, Visual Studio thinks that it needs to add anImports MS.Internal.Xaml.Builtinsto every auto-generated XAML partial class (= the nameOfXamlFile.g.vb files), resulting in the following warning:warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.I can remove the Imports line, but, since this is an auto-generated file, it reappears every time that the project is rebuilt.
