i have a service to run against the database. when it is run on my windows 2000 server platform with 2.0 framework , everything runs smoothly. The problem is when i tried to run the same service in a clients computer, it prompts an error as below:[service cannot be started. the handle is invalid] from what i think , the errors gotta do with the permission for the user. can you guys help me sort this out? or at least give me a couple of possibilities what might have occurred ? thanks in advance.. appreciate any helps given

If you can provide me with more information, I might be able to help...
Is it a smart client app? Or a simple WinForm?
Is the database on the same computer as the client?
Is the database SQL Server 2005? 2000? Access?
I also suggest that you take a look at the exact time when this exception occurs using the debug on a computer with a similar configuration from your client's.

Hi, I've copied a C# server program straight from another computer to my laptop. Im running on Visual Studio 2005 PE version 8.0. Everything compiles okay and installed perfect. The server program have its own install actions to use in the setup project. Now, assuming I did not touch the code and just for fun, I remove the installaction.dll file from the setup project and then add it again back again and adding it back in the custom action....it still compiles perfect. But this time when it installs, it gives me a "Object reference not set to instance of object" error during installation. Then when installation completes and when I run the server, it gives me problems. So anybody have any ideas why it gives me this problem when I just delete and then add back the dll file without altering it whatsoever? Any suggestion or help will be appreciated.
Please note that I have disconnected myself from the VSS.

By removing the file you've probably wiped out some code dependant on it. Just putting the file back won't replace that code. You'll have to see if there's something missing in your project that references that .DLL.

I dont believe any of my code depends installactions.dll file.... I thought the reason it might act like this is maybe because the installactions.dll file was created using an earlier version of .NET and right now Im using the latest version.

If you install .net 1.1, in your laptop, you will not get any such type of errors...
The same is the case for me...why it happens I dont understand, some backward capability is missing in .Net2.0. I guess???

Using ClickOnce? I don't think so. I think you'll have to write your own application that uses the System.Deployment namespace to figure out if various .DLL's in your app need to be updated, downloaded and installed. I have no examples of how to do that. It's never been one of my requirements and I also rarely use ClickOnce.

I don't work for MS, so I have no idea.

It's a nice idea, but I haven't been able to delve into it to see if it supports the distribution model you want it to.

Sir,
can any one tell me how to create a UI using .net technologies. I want to display and edit word and excel files in it, similar to DSO Framer control. Thank you,

You can't. Sorry to keep shooting you down, but the only way to open word and excel files, is to use Word and Excel. Unless you wrote something on the server that controls Word and Excel, and then your own program that edited the data. You need Word to open Word files, and you need Excel to open Excel files.

I dont say that I dont use word and excel. But even though I need to display and edit the files by using a UI. Please try to understand my intensity of the problem. Thank you.

That's a massive undertaking. If you don't want to take me at my word, see the size of the source code for open office. You'd need to write something that big to make it work. If you need something more capable than the Office COM controls (mainly limited in terms of menu/toolbar options IIRC) your only practical option is an activeX container. Since porting/writing one (this is what the DSOframer is) appears to be beyond your abilities you'll have to look at finding and buying a commercial one from a component vendor.

Yes sir Dan,
I am ready to buy it. But the only condition is that control must be made by using managed code, the great architecture from Microsoft. Thats what I am always requesting to Christian. But he is feeling bad. I am sorry if I trouble you in any way.
As I am optimistic, I am trying it to find. Thats the problem is. Thank you.

Why?

Because it is 'the great architecture from Microsoft' :P
Seriously, this guy wants the functionality he's found in an ActiveX control, but his client doesn't want it to be ActiveX, because of security issues. He thought if he wrapped an ActiveX control in .NET, .NET would allow it to run without any security requirements. I am praying he is wrong....

Dear Christian, this is too much ya aqui. Yes, it is deffinitely more secured. You can ask to mMicrosoft also. It is secured because, .Net uses managed code, which will be rendered at client in the form of html which is secured and light weight. So please tell me, if you find any solution. Please. Thank you.

You are totally, totally lost. You're talking about ASP.NET. There is NO way that you can send just HTML to the client, and render/edit/save Word and Excel documents. Well, with a lot of javascript, perhaps, but if you do it, you should quit your job, and start a business selling the control you write.
indian143 wrote: .Net uses managed code
That has nothing to do with security. ASP.NET requires no permissions because, unlike ActiveX, it's not code on the client end, just HTML. Which is not enough to do what you want.

And I said 'I am praying he is wrong', not because I want you to fail ( I wouldn't be trying to help then ), but because if you're right, then we all have major security issues on our desktops.

So, is there no way except using activeX. Ok, then. Pray that may God help me. As I like to research the new things, I have been trying. If you get any idea, please send me to my email also.
Because, I keep those things with me, where I have been struck. But right now I am leaving this because I have to go with other things also. But I remember this as, I faced a real problem here in my development experience. And I am always thankful to you because you did more as a friend. Thank you.

You and your client seem to be under the misunderstanding that all things .NET are secure. Nothing could be further from the truth. I can get you to install an application on your machine that looks like it does it's job quite nicely, but in the background is actually going through your hard drive deleting files at random, under YOUR user ID.
You are also under the mistaken impression that a .NET Control does not need to be installed on the client-side in order for the client to use it. Again, nothing could be further from the truth. ESPECIALLY one that wraps an ActiveX control. Now, BOTH controls have to be installed on the client-side in order for it to work.
