What is 'fields'? Could you not do this? mappingName = fields["name"]

Hi Josh,
Thanks for the reply. 'Fields' should have been 'FieldValues' - signature below.
Public ReadOnly Property FieldValue(ByVal dataSource As String) As String
Basically, I have a collection of objects which are wrappers to their underlying field values (eg datasouce and value string). However, I want to be able to access the field values directly, through my FieldValue property, rather than indirectly though the various other accessors. I know this sounds a lot like a datatable, but trust me 
Tried you suggestion, but no luck. A string is required, and I thought the following would have worked:
.MappingName = "FieldValue(" & vbQuote & "wmsName" & vbQuote & ")"
where 'wmsName' is the argument I want to pass to the FieldValue property. No joy though.
Thanks for your help,
Luke

You're making the assumption that the MappingName property will dynamically invoke your FieldName property, based on some type of parsed interpretation of the string value. I assume that MappingName is not built that way.
Why did setting MappingName to FieldValues("whatever") not work? What was the actual problem?

Hi Josh,

Just the usual problem when mapping names don't match a property in the bound type: the column is not displayed. No exception or anything useful to help debug! .
I accept your points about dynamic invokation - maybe I was hoping for too much.
Thanks

Hi Folks,
I would like to write an installer for my C# program. I have no experience with installers, but I know there are some programs/tools to help me do it.
Can you recommend to me how to approach this? Maybe there are some tutorials that can help me.
In addition to the common installation tasks (copying files, registering, uninstalling) I would like to do the following in the installer:
Check if the required version of the .NET framework is installed, and if not, install it;
and the same for the Managed DirectX version.
Thanks for your help!

Add a Setup Project (or a Web Setup Project) to your solution. Search CP for articles about how to configure it.

NSIS[^] is by far the best installer I've come across, although it will take a short while to become experienced in it.
VenisIX[^] is a good editor with a built-in wizard for generating scripts.
Take a look at SharpDevelop's[^] installer for functions to check for .NET Framework existance.

It probably means that the user account under which the worker process is running cannot read the disk directory in which the files are stored.
Ensure that the permissions on the directory include the account which the worker process runs under. You can change the worker process identity by editing the properties of the application pool containing the application experiencing the problem. By default this is the NETWORK SERVICE account.

I get a DevicePath using SetupDiXxx functions:
\\?\usbstor#disk&ven_fujitsu&prod_memorybird&rev_1.14#0739035033a1&0#{53f563
07-b6bf-11d0-94f2-00a0c91efb8b}.
How can I use this device path to retrieve a drive letter in format of "F:\" ???
When I use GetVolumeNameForVolumeMountPoint function, I always receive "error C3861: 'GetVolumeNameForVolumeMountPoint': identifier not found, even with argument-dependent lookup" even though I've already add statement in my code : #define _WIN32_WINNT 0x0502

Hi All,
I'm a complete newbie to coding and the like, but I have been given an urgent deadline to create something, and I haven't a clue at all what to do.
I have been asked to create a a progamme that will have a desktop Icon, and will launch a window with no bottons or anything like that (similar to an IE popup window) and only have a title bar at the top (with the name of the programme), and simply display a .html or .php page that I have already created for it.
I'd assume that for a seasoned code guru, this probably sounds so simple and a silly request for help, but I really don't have a clue!
Any help will be most appreciated, and many thanks in advance!!
Regards
Kevin

Sounds a bit odd to me but here a short description:
1. Download and install the Visual Studio C# Express Edition.
2. Start it and create and new windows forms application.
3. You will see an empty form. Click it and change the properties as you like.
4. Look at the tool box at the left. There is a WebBrowser control int it. Drag it onto the form.
5. Change the properties of it as you like (in one of them you can choose which file should be displayed)

Hi,
Thanks for the quick response!
I have followed your instructions, and it works well to create the application, although none of the video in the window will load. However, if I launch the HTML file in IE, the video does work.
I assume I'm doing something wrong somewhere?
The video is Windows Media, four seperate feeds embedded on a webpage, using activeX

Hi there,
I want to use a custom configuration section of the following form
(using the new .NET 2.0 classes, not the old
IConfigurationSectionHandler interface):
<mySection>
<Setting1>Value1</Setting1>
<Setting2>Value2</Setting2>
</mySection>
But all examples I have found only describe this form:
<mySection>
<Setting1 Value="Value1" />
<Setting2 Value="Value2" />
</mySection>
I have this second form working, but I would like to know if the first
form is even possible, and if yes, how to do it. I'm using the
attributed model, so a small example with the attributed approach would
be appreciated.
Thanks!

Sometimes (less that 1% of the calls) I am getting “System.Runtime.Remoting.RemotingException: Port is Busy: All pipe instances are busy” on remote method invocation when using IpcChannal.
Has anybody experienced the same problem?
Suggested solutions?

Maybe trying to disconnect/hand off from the ipc channel will resolve this.

I'm going to guess that when calling it from the same server, it uses Windows Authentication. The ASP.NET runtime then uses your credentials to write the C# code that it generates to do the XML serialization, which it then calls the C# compiler on to generate an assembly to load.
When you call it from another server, it's probably using anonymous authentication, which means that the serializer code is running as the ASPNET user (Windows 2000, XP, by default) or the NETWORK SERVICE account (Windows Server 2003). The actual account used can be modified in web.config on 2000 and XP and by changing the application pool settings on Server 2003. I suspect that the error is occurring because the Access Control List on the C:\Windows\Temp folder doesn't allow this user to write to it. To change this, right-click the folder in Explorer, go to the Security tab, click Add, select the appropriate user, and check Modify in the Allow column.

I have been developing some extensions to bollwerkj's article "How to use Managed C++ to Automate Excel" (http://www.codeproject.com/managedcpp/ExcelwithMC.asp[^]) and one key line is
using namespace Microsoft::Office::Interop::Excel;
A couple of weeks ago, I loaded the new Windows security updates, and now I am getting compile errors that say "Interop is not a member of Microsoft::Office." Anyone have any idea how to undo what I've done and get this back? (I don't know for sure that these two events are connected.)
I went back to through the article and re-installed the PIAs, but that didn't fix anything. The files were all available. Has anyone else run into this kind of problem before?
Any suggestions will be greatly appreciated.
Thanks,
Dave
