Hi,
In my C# apps, I've used WNetAddConnection2A all along to connect to Netware servers from Windows applications, using '[DllImport("mpr.dll")] private extern static WNetAddConnection2A ( ... )'.
I've recently needed to map a drive to a Netware server from a Windows service, however this approach returns Error 1420: The window is not a valid dialog window.
Does anybody know of a way around this problem, or better still how to map such a drive using purely .NET functions, without having to refer to the older WNet set of functions?
Thanks,
Rob.

You can't map a drive inside the service because your service doesn't have a window. You would be much better off using UNC names to get to the Novell box instead of relying on mapping a drive.

There's nothing in the .NET BCL to do this for a Novell client.

Thanks for your reply Dave. It's surprising that there is nothing in the .NET BCL that can accomplish this task.
Anyway, I've tried your suggestion of using UNC names. I'm using the DirectoryInfo.Exists Boolean property to verify that a remote directory exists on the Novell server before I start to work on the files inside. It works just fine from a standard test Windows app that I wrote, but from within the Windows service the same piece of code can't find the same directory.  Weird!
The piece of code in question is fired every 15 seconds as part of a timer event. Even though this should be plenty of time to find the directory I tried increasing the timer interval to 30 seconds, but it didn't change the outcome.
Any more ideas? Have you ever experienced anything similar?
Thanks again,
Rob.

It's not weird. It's just that you're making some assumptions that's getting you in this trouble. What account do you think Windows Service run under, by default? It's not your account, it's the Local System account, which has no rights to any network resources what-so-ever, and you can give it the rights either.
Go into the Services control panel, under Administrative Tools. Double-Click your service to get it's properties. Click on the Log On tab and you'll be able to change the account that run service runs under to one that has appropriate rights to the server.

I am writing a program which will use another application for communicating with, but I want to load this other application in the background when my main application loads, and then just send a windows message to my "background" application telling it to show/hide...
What I have done now is to have the "background" application started from the main application with a Process.start(filename). In the background app the code to run it looks like this:
<br />
Application.Run(new BackgroundAppFrame()) <br />
(from it's "static main" method). However it doesn't seem to be possible to do this without the frame being displayed (I guess the Application.Run() first invokes the constructor and then sets it visible or something like that... And then of course Application.Run() will block so I cannot set the hidden property).
Any suggestions on how to solve this? Set the size to 0 instead? Or move it out of screen? If you have a clean solution to this problem please tell me..

From your previous post, you're going about this the wrong way. Introducing a second application for such a small operation will just make your application that much more difficult to support.
You haven't made drag and drop easier by creating a second application, only more difficult. Check into that article I replied to your previous post and you'll be able to put together a modal form that itself can host multiple forms where you can then do what you were talking about.

I have App.exe which uses Dll.dll, I also add classical Microsoft manifest file App.manifest.exe to enable XP styles for common controls.
Now question how can I disable influence of manifest on Dll.dll
Which means I want that App.exe continue to use
comctl32.dll (ver 6) new one
but
Dll.dll should use
comctl32.dll (ver 5) old one
Load / Unload library - already try not helps
#define/#undefine IE_CONTLOLS - already try doesnt helps
I need to customize body of manifest somehow include or exclude styles in the dependency section
Thanks.

Hello,
I have a user control which contains a button that shows a form under my user control. The user controls size varies so I change the size of the form and its controls - a panel and checkedlistbox and than call the Show method. Before the call the Size properties for the form and its controls are correct, but after the call the width of the form is set to 112 pxl. If the form is bigger there is no such problem, its the smaller sizes that cause the problem. Any ideas what could be the reason and how to solve the problem?

Hi,
I wanna to add controls in rutime depending on some coditions in a tab control that its pages is added dynamic (I amde that part).
I made all things to add that conrtols to tabcontrol but there is no errors and nothing is displayed.
Regards,
Hisham Galal

The commons things to forget when adding controls are
- calling control.Show()
- actually adding the control with tabPage.Controls.Add(control)
- moving and sizing the controls so that all of them can be seen
If your app does those three steps, please post the code that adds the controls. I really cannot read from your thoughts what's missing.

Hello,
Is it possible in VS.NET to make a separate dll's for images alone. What I want to do is to change images in a C# program by changing the image dll's, so you dont have to open VS.NET to do that. (kinda like changing languages in a C# program).
