VS 2010 Application Showing Different Behavoir When Installed Versus Running?
Jul 4, 2011
I have a situation with an application of mine where I noticed I get a different result when the application is installed in comparison to it running in Visual Studio. If the application is installed a certain aberration pops up in this computer graphics application at a certain point in one of the screens but if I run the same group of settings or you could say the same "screen" running the application from Visual Studio I don't see the aberration ever happen. I tried deleting the bin and obj folders and then rebuilding before creating an installation and it doesn't change anything and whether I use InstallShield or create an installation using ClickOnce I still see the same issue. I have Enable application framework unchecked but found it makes no difference checked or unchecked
I am writing a web application using .net 3.5 and vs 2008 which allows people to add data to a db via a control panel front end.Objective: Before committing one of the fields to the db i would like the user to answer Yes, No or Cancel to confirm their action. I have tried to implement this with a modal dialog box or message box but the following error appears: Server Error in '/' Application.
I have an application that has an Ms Access 2007 DataBase which runns great if access is installed. Is there any code that I can use in vb that I would be able to run access with out installing it.
When it is run, screesavers and screenoff is prevented somehow.. I have narrowed it down to this code.
[code...]
The above code is what makes it possible for my application to active two forms when only one is activated.. But it is somehow this code that prevents my screensavers and power settings from working.. Do you have any idea how to change the code so it doesnt prevent my screensavers and power settings?
I have a simple windows Service developed in VS.net 2008 and VB.net. When I install the service using Installutil.exe from the command prompt it is working like a charm.
When I try to add a setup project and set the output and build and install it though it says successfully installed, it is not showing up in the services.
The event log shows that it is successfully installed. I just did check the registry, it did place the assemblies in HKEY_CURRENT_USERSoftwareMicrosoftinstallerassemblies.
But I don't understand why it is not showing up in the services listing. I refreshed and restarted.
I've finally gotten multi-threading working on my application, but now I'm having trouble showing forms when I need to. I currently have three threads in my program: one for updating a textbox, one for transferring files, and one for displaying forms. Here's a snippet of code from my program:
[code]...
I'm getting the error: Control 'frmXCopy' accessed from a thread other than the thread it was created on. I know what this means, but I can't find a way to make the ShowForm Sub run off of the main application thread.
My application required .NET Framework 2.0.Currently, if it is not installed the user recieves the following error:The application failed to initialize properly (0xc0000135)'.It becomes extremely tiresome repeating to users that this is because the framework isn't installed. Is there some way to check if .NET framework 2.0 is installed before running, or in some way change this cryptic message so the user knows immediately
Is it possible to start an application not being visible? This application is a batch application and my application would look way better if I could hide this batch.
I have one PC whereby the OS has been installed on E: and it has no C: drive. Onto this I have installed my .Net 4.0 WPF Application which runs fine.
However, when I try to access a crystal report it gives the exception below. This user is able to access the report from its network location in windows explorer so I assume the act of asking Crystal to copy it locally is causing a problem?
Therefore, can anyone advise where the local copy will be created and/or how I can control this.
We currently have +- 20 different console application developed in VS2008 and running at different scheduled intervals, all controlled by Windows schedular. The problem we have come accross is that it is becoming increasingly difficult to manage and maintain these console apps. In some instances a console app will just fail or never run to start with and this creates a lot of problems. In many cases one console app is dependant on another and if 1st one fails well...you see where this is going.
I am looking for a new solution that will help us to trace, debug and manage these console apps better. We are preferably looking for a gui front end, maybe windows app where we can set the intervals for them to sun and view some error reports if they did not run.We are port all the code for the console apps to which ever new appliocation we develop.
I have created a Customized Excel template for Office 2007 using VSTO. currently i am showing this template under my templates. is it possible to show under Installed templates?
like we have in office 2007 Billing Statement, Blood Presser Tracker, Time Card , etc. Is it possibe to show the template which is created by me; under Installed templates?
I have opened an existing project and made changes in the design mode. (For example, I added a new button.) But when I tested the program using Start Debugger, none of my changes showed up.
just want to know what is the difference between these date values?Once some one told me that its difference is server date and client date but not sure which one he meant.Below is 3 type of date currently I'm using and don't know what is the difference between them.
DateTime.Now is from System.DateTime.Now Now is from Microsoft.VisualBasic.DateAndTime Today.date is also from System.DateTime
I have created an shareware application using vb.net visual studio 2008 for windows desktop, and packaged it using innosetup 5.3.8. The problem is when i have installed the application in C:Program FilesApplication and it runs successfully(use trial period of the application), Im also able to install the application once again freshly with the same setup by installing in different directory.eg C:Program FilesApplication new . The application in C:Program FilesApplication new does not have any settings of the already installed one.
Where do i went wrong . Do i need to take care of this in my application(vb.net) or innosetup. How to take care of the already installed path in innosetup or carry the settings of already installed application to newly installed path by upgrading the older one.
I dont want to write any thing in registry because the application does not want any administrative permission requirements.If i install the application in same path it gets updated with the older settings being taken over to this new one and it works fine.
I have designed and published my small created app with WINDOWS FORMS using VB 2010 EXP on Windows 7. I can only install the app on the machine that I used to develop the app.I want to install the app on another computer but I cannot. I usually have error reports.
Example:Unable to install or run this application. This application requires Microsoft Common Language Runtime 4.0.3 to be installed on your computer.
what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.
I have a few questions regarding the GUI applications.I am aware that Console applications are non-event based programs which do not have the pretty GUI interface.Having done C/C++ on *nix with a main() as the entry point and in Windows 3.1 with WinMain as the entry point into the application, I am trying to figure out the entry point into the VB application.
My company is in the process of analyzing how to convert and upgrade an application that was written in Microsoft Office Access 2003. Recently we purchased Microsoft Visual Studio 2005.
The first step we'll probably take will be to convert the Access data to Microsoft SQL. Is there a recommended way of doing that? What should be done with the VBA code?
The second step we're not sure about. We're wondering in we should develop all new software in VB or that we should still use VBA, if possible, after the data has been converted to SQL.
I have recently created an application with Visual Basic.NET. I published my application and installed it. Now the question is that I need to know where exactly does the application gets installed on my system ?
I had done one application using api which send the message to given number. The working of software is very fine without any error working on windows XP SP2. I heard that vista already contain the .net frame work so didnt installed .net frame work in machine. I checked in vista it shows .net frame work is in machine. But when same code i tried to run on Vista it gives the error. Error is as follows
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I had a .chm file I used in VB2008 and I'm having trouble getting it to work for VB2010. I use the code below to reference the file.
vb Module HTMPHelpAPI Public Const HH_DISPLAY_TOPIC As Short = &H0 Public Const HH_DISPLAY_TOC As Short = &H1 Public Const HH_DISPLAY_INDEX As Short = &H2 Public Const HH_DISPLAY_SEARCH As Short = &H3 Public Const HH_HELP_CONTEXT As Short = &HF Declare Function HTMLHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" (ByVal hwnd As IntPtr, ByVal lpHelpFile As String, ByVal uCommand As Int32, ByVal dwData As Int32) As Int32End Module
I then call it from my menu using this:
vb Private Sub HelpToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HelpToolStripMenuItem1.Click HTMLHelp(IntPtr.Zero, "PE Files Help.chm", HH_DISPLAY_TOC, 0) 'Dim sHelpFile As String 'Dim sStartupPath As String 'sStartupPath = Application.StartupPath.ToString 'sHelpFile = Replace(sStartupPath, "in", "hlp") & "PE Files Help.chm" 'Me.hlpHtmlLocal.HelpNamespace = sHelpFile End Sub
I had found the commented out portion online and tried to get it to work, but nothing will bring up the file. Do I need to have it loaded into VB.Net somehow or point to it or does it need to be in a certain location?
I've been fiddling with this for ages and can't get it right. If you have this in C#:
videoSource1.NewFrame +=new NewFrameEventHandler(videoSource1_NewFrame); void videoSource1_NewFrame(object sender, NewFrameEventArgs eventArgs) { // stuff to do in here }
How would write it in VB? My head is spinning with AddHandler and AddressOf and I can't seem to get it right.
I am interested in the pros and cons of data tables and arrays in VB 2010. I programmed decades ago in FORTRAN and used arrays extensively.However, I frequently see data tables in code snippets and don't know when they should be used in lieu of an array.
I make a lot of programs that require an internet connection to download things from the web.At the very beginning, I used WebClient, as I didn't know Socket & how it worked.But now, I use Socket all the time, altough it's more lines of code. It seems to work faster then WebClient.I am interested if this is really true & why WebClient is slower (so is HttpWebRequest) then just a Socket.I've setup 2 threads which starts on the click of a button (WebClient thread starts first), the Socket beats the WebClient by just some milliseconds, but still.Each way has it's advantages & disadvantages, e.g.: if you use Socket, you need to write the header yourself & parse the response header.My question is, which one do you prefer & why ?Do you know why WebClient & HttpWebRequest are slower then Socket, as I assume, WebClient & HttpWebRequest both use tcp to download the things.
I have a program that backs-up remote locations to a centralized FTP server. Upon successful completion, a record is written to a SQL database with the following information:
I am currently managing the program by running a report on who has written a record to the database. If the record is not written, I manually go in and backup the necessary files.The problem with this, is that it can take up to 30 minutes/day to do this task. While that's not a long time, it's getting somebody to be dedicated when I'm off and that has proven to be difficult.
I want the program to automatically search for missing records, but I'm not sure how to do this. I was thinking about bringing in the last 30 days with a SELECT statement and then comparing the information that I have in the SQL database versus a calendar control (or something). I need to make this process completely automated and not very intensive on the SQL server. I only have the following
2010 Sub FindMissingBackups(ByVal DaysToCheck As Integer, ByVal StoreNumber As String) Dim TodaysDate As SqlDateTime = Now() Dim PastDate As SqlDateTime = DateAdd(DateInterval.Day, -DaysToCheck, Now())
I prefer having total control for data access, populating recordsets (now datasets) precisely via a connection string and SQL select (or stored procedure call), etc.Now I wonder whether I really should be using the Data Sources option which just popped up on my radar? From the little I've seen so far, it seems to bind an entire table to a control, whereas most of the time I only need a small number of records from large tables.Before I spend a lot of time investigating, I hope a quick word from you might help me feel happier continuing as I am, or whether I need a kick up the backside towards a Better Way.
i am trying to develop a project for my academics...i.e, windows application s/w... how to get the thumbnail view(in win7 taskbar shows in that manner?) of all applications that are appearing on taskbar with code in vb ..
I was a VB6 programmer. And back in the day global variables, functions and subroutines were put in a module. The program started in the module using a sub named Main(). Now in vb2010 it looks like using sub Main() is possible only for console apps, which is not what I want, I'm still trying to write a windows app but it looks like everything has to go at the top of the starting form?? How is this good coding practice? Shouldn't public vars and functions be in their own module?What is considered best practice?Are there any links that would walk me through the differences between vb6 and vb2010?
