A VB2010 program fails to build because it doesn't recognise left() and right(). mid() works, though.
Microsoft.visualbasic.left() works ok.
Yet, in another VB2010 program, left() and right() work ok.
At college we run 32 bit computers and at home i build my programs to bring in but i have a 64 bit computer, i need to know if theres a way so it builds and saves the program as a 32 bit on a 64 bit computer.

Got Visual Studio 2010 Express Edition and have been building an app on Windows 7 64bit, then bought that app into work to continue work on Windows XP 32bit.When I load it, it will run first time happily but when I try and run it again it either says The Operation could not be completed or just freezes, crashes or does not responding, yes if I build the app to an exe file it works fine everytime?Due to the fact of odd errors etc I am really baffled and frustrated why it's so random?

View 5 RepliesI have a setup project in my solution. There are interop dependencies on msADOX and oledb32. On my Vista build machine these dependencies don't show up in the "Detected Dependencies" list (only the two interop assemblies), and my solution builds just fine.
On the production build machine (XP), the build fails with two errors: ERROR: 'oledb32.dll' should be excluded because its source file 'C:Program FilesCommon Filessystemole dboledb32.dll' is under Windows System File Protection.

I got a panel that i am adding labels to. I have autoscroll enabled on it so when they fill the viewable space it scrolls. but i need to put the labels to the left unviewable space(when left scroll is already at 0) The label is placed but i dont get the scroll bars and i cant force it to scroll to a - value.
Is this even possible? Same thing with UP.
Or is the Scroll only limited to Bottom and Right?
I am building a Setup project for a Web system using Visual Studio 2008. I upgraded my development machine from Windows Xp to Windows 7. The problem started with Windows 7.

When I transfer the system to a machine running Windows Xp or Windows 2003 Server it builds successfuly.
View 4 RepliesI've been working straight since yesterday trying to get this to work. I'm a noob to RegEx and I've tested out about 5 different RegEx "builders" but each of them require you to navigate through the options to build the Regex...each of them has failed when I try to use them.Is there an application out there free/paid where you select the line you want to grab and the RegEx is auto generated from that highlight rather than having to try to build the line of code?

View 1 RepliesI have a VB program that I'm trying to deploy. On my machine (the app works fine straight from VS), when I try to install it from the webpage, it asks me to setup .net. I only have a choice of repairing or uninstalling .net. I've tried both but both fail at the moment. The problem with the repair is, although it goes through the entire repair procedure, it then asks me to restart my PC, but when I hit 'restart', nothing happens. So I restart manually, but when I try again, I just have to go through the same procedure again.

I wrote an application on windows XP using visual studio 2008. Based on the .net framework 3.5. For some reason that I do not understand the application refuses to run on windows 7. You would think that if the .net framework 3.5 was installed on the windows 7 machine it would run.
View 10 RepliesI'm catching the following error in a publishing script (VB.Net) I'm running:
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
The code that fails is:
My.Computer.FileSystem.WriteAllText(path, content, False)
It runs fine for most of the files but some have a '~' in the path and those ones are all failing.
Just to clarify: i am using the full path an example of the path i am having problems with is "c:/websites/xml/myfile~test.xml" the ones that work are "c:/websites/xml/myfiletest2.xml"
I currently have this line of code which has been working for the past 6 months:
If IsNumeric(txtProductID.Text) Then

All of the sudden, no matter what kind of entry is put in txtProductID (including plain numbers), it fails! Is there reason for me to be going crazy over this?
I am currently using the AsyncFileUpload in my VB.NET web app. Locally it works perfectly, however on the server it fails to upload a small file (<9k). I can't even seem to debug this as in JavaScript handlers I have no idea as to how to get the error reason.

$get("<%=LabelErr.ClientID%>").innerHTML = "Unable to Upload file for the following reason: ", "<span style='color:red;'>" + args.get_errorMessage() + "</span>";

I have just finished my application using VB in Visual Studio 2005 and it works fine on my Win 7 development machine. But when I install and run it on an XP machine it fails with an unhandled exception:System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154.
I've googled the error message and the solutions seem to be 1) compile as x86 (was doing that anyway), and 2) register the dll on the machine But firstly I'm not sure which dll I need to register, and secondly I don't want to be going around registering dlls - the whole point of the installation programs is that it should just install and configure everything automatically..
