View 2 RepliesI am trying to create a update application for Windows CE.
It will go out on the net to my site and see if there is any new updates but I am having a problem doing that.
Firstly it is working fine if I create it using a 'Windows Application' but as soon as I Copy + Paste the code to my 'Windows CE' app (smart device, windows CE) it comes up with an error.
I am using .net framework 2.0.0 and vb.net 2008
Here is the code which I am using:
Code:
Function DownloadFile(ByVal sURL As String, ByVal pProgress As ProgressBar, ByVal Filename As String, ByVal Prefix As String, ByVal Rename As Boolean) As Boolean
Dim wRemote As System.Net.HttpWebRequest

I know there are many posts about updating an application with UAC turned on. We have a huge application and our own update program for updating that. We don't want to use the UserAppData area to install our exes. We do mostly custom programming so updates are a part of like for us. My question is: If we get our update program digitally signed can the standard user with UAC turned on accept those changes without administrator privileges and can that be done to a VB6 executable.
View 8 RepliesI was wondering if there is a way to update Windows Vista via a Vb .Net application.
I wanted to use Vista's WUSA.EXE, but it seems that it is only able to do specific updates in a specific location, not all updates.
Info on WUSA.EXE: [URL]
What are the best practices to develop a software in such a way that I can release updates, I mean I can release an update which replace the existing executable but in case I have added some new references (dlls) to the project this won't work ? Is there any way I can do it without running an MSI?

Is it possibel to use update panels and update progress controls in windows application or is that reserved for web apps only. I am looking at applying some progress controls (like a spinning wheeel etc) when loading a crystal report that take about 30+ seconds.

View 13 RepliesI am working with Visual Studio 2010 Pro. My OS is Windows 7 x64.I am migrating a VB.NET application that was written for .NET 1.1 / 1.0 in a much earlier version of Visual Studio.The project converted without many issues and works except for on thing. The Jet 4.0 libraries are not available for Windows 7 x64. I understand that they have been replaced with ACE Provider, with actually has an x64 version.
I need to be able to manipulate an MS Access 2003 format database (MDB). I am planning to target .NET framework 2.0 to ensure maximum compatibility with downlevel clients. (I can't install framework 3.5 or 4.0 on these machines). I need to continue supporting MS Access 2003 format on these machines. If I switch to the ACE provider, wouldn't I have to at least install the Microsoft Office 2007 data access components on all of the machines that will run this application? What's the best way for me to target these older machines without having to install any extra software? They already have .NET 2.0 installed and have the JET 4.0 libraries registered.

View 1 RepliesThis application uses a Microsoft Access database named Books to keep track of the books in a store. The database has one table named tblBooks. The table has five fields. The BookNumber, Price, and QuantityInStock fields are numeric. The Title and Author fields contain text. This application should allow a user to enter an author's name ( or part of a name ) and then display only the titles of books written by the author. Displaying the information in a DataGridView control; however, don't allow the user to add, delete, modify, or save records. I need to allow the user to specify the records he or she wants to select while the application is running. Also, i need to Add a text box and a button to the BindingNavigator control. The user will use the text box to specify the records he wants to select. The user will use the button to tell the computer to display the selected records. I also want to display the total value of the books in the store. I am not getting the BindingNavigator control in the component tray in my program I've included. Also I am working on the code for the display button but I need some tips. I am trying to complete this program and only expect guidance.[code]

View 1 RepliesI want to design a application which can support two different types of databases same time e.g; when we install, it will ask which db it has to support and based on initial selection it should work with any db without changing anything in the application.In short it has to be developed keeping in mind that user may have either MS SQL or MySQL. It should support both.

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.

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.
View 3 RepliesI currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
i made an application for serial communication. for this application i need to set delay time. during this delay time i m doing some other task. So for those task i need to take back control from delay function, for this purpose i am unsing Doevents() function.Its work fine On other OS (XP, Windows7 32/64-bit). But Application.DoEvents() function halt and crash in windows vista.
