Any managed code running from an untrusted source (i.e.: any network share) runs in a restricted sandbox. Go to MSDN and search for "Code Access Security". You've got a bunch of reading to do...

i don't want to code access security, i want to run my exe file from network.

You might want to take a look at what has been suggested - it's been pointed out to you for a reason, i.e. you really need to learn how to do this if you want to break out of the Sandbox. Dave IS a MVP for a reason you know.
Deja View - the feeling that you've seen this post before.

Well, understanding CAS is a requirement when dealing with managed code, especially in running from untrusted sources. It's not an option. The only reason why all your code to this point works is because of the default security setup under the .NET Framework. Now that you've ventured outside the defaults, you've having problems. You're either going to read up on CAS, or you're going to be stuck writing simple Windows Forms app that have to be run from a local drive.
In order to "run my exe file from network", you must understand CAS. This is not optional.

ok, thanks.
my problem was solved, but is that any way to perform this operation by code ?
my another question :
if my app use com dll or ocx (non dot net), even above solution was not solved problem and how to run it in network ?
many thanks

No, there isn't. Can you, as a normal User, give yourself PowerUser permissions?? Of course not. Managed code has the same restrictions. It cannot give itself permissions greater than that of the security context it's running in.

There was a reason why I suggested you read up on Code Access Security. If you want the answers to these questions, you MUST understand how Code Access Security works. If not, you're groping around in the dark hoping to find something that works for you in this particular instance. God help you if if breaks, 'cause if you don't understand why it broke, you're not going to be able to fix it. That's what the documentation is for and why I told you to read it.

your being a little melodramatic aren't you? I mean Visual Basic is all about developing software without understanding how anything works, right?

That's the general perception, isn't it? However, if you really want to write code, in ANY language, you have to understand how stuff works, afterall, it's just as easy to write crap code in C#! At least in C++, you stand a better chance of crap code just not compiling...

Hello,
I have a little problem with the creation of a WORD document with C# and Visual .NET.
The aim is to write down some chemical structures.
I read the name plus structure information from the database and then use
a for-loop to
___write a 1x1 - table for the structure-name (I want it to be in a frame)
___move down a line,
___type a paragraph and then
___paste the structure,
___followed by some more text/paragraphs
for each structure.
When I check it with the debugging function, all is as desired, but when I don't,
the first structure is as desired (name in a frame; structure; text)
but then I have the next frame/ table-cell, containing:
___name
___structure
___text
___name in a frame
___structure
___text
___next frame containing
______name
______structure
______text
______next frame containing
_________name
_________structure
_________text
_________next frame containing
____________name
____________structure
____________text
____________...
Does anybody have a clue what happened or how I can prevent this behaviour ?
Best regards and thanks !
Dirk

Well, after having several troubles getting a C# app working out of a
Firefox plug-in ( see here[^] ), i finally managed to connect my
C# code, compiled as .dll to a C++ Firefox plugin .dll
Right now, i'm able to fire my C# app out of the browser window, calling my
classes within the FF plugin dll. [ It'll open up a separate form. ]
What lacks now is to have my app being painted DIRECTLY onto the plugin space,
the space reserved for the plugin in the website displaying it, that is.
The plugin gives some handles for that:
NPBool nsPluginInstance::init(NPWindow* aWindow)<br />
{<br />
if(aWindow == NULL)<br />
return FALSE;<br />
<br />
mhWnd = (HWND)aWindow->window;<br />
if(mhWnd == NULL)<br />
return FALSE;<br />
<br />
lpOldProc = SubclassWindow(mhWnd, (WNDPROC)PluginWinProc);<br />
<br />
SetWindowLong(mhWnd, GWL_USERDATA, (LONG)this);<br />
<br />
(...)<br />
Question now is:
- I do have my app functionality sitting on a UserComponent class, also could
pin it onto some form.
- How to paint that form [ UserComponent ] INTO the plugin space ?
- Also, as it isn't possible to create global instances of managed ( C# )
classes in unmanaged ( C++ ) context, how can i have my app running
simultaneously to the plugin ? [ I wondered, if it would be possible and
appropriate to run the C# in an own thread, then grabbing graphics
whenever needed and displaying / painting it in the plugin space ... ]
Hope you can figure out what i'm trying to do.
Any help is highly appreciated.

Could you get the DC for the window using GetDC from Win API, then get the DC for your UserComponent (through the graphics object), and finally use BitBlt to copy the image from your UserComponent class to your target area?
SomeMethod(Graphics yourUserControlGraphicsObject) {
Rectangle mRect = new Rectangle();
IntPtr trgDC = Win32.GetDC(mhWnd);
Win32.GetClientRect(mhWnd, out mRect);
IntPtr srcDC = yourUserControlGraphicsObject.GetHdc();
Win32.BitBlt(trgDC, 0, 0, mRect.Width, mRect.Height, srcDC, 0, 0, Win32.SRCCOPY);
yourUserControlGraphicsObject.ReleaseHdc(srcDC);
Win32.ReleaseDC(trgDC);
}
Does this help?

The same way you read any file, you know and use the file format specification. Unless of course you are a magician and then you can just use magic.
|
|
|
|

Oh.. so kind of you for showing your magic show here Mike. I appreciate it.
But I think you must have missed the actual question that was posted in asp.net forum originally.. which is how to connect to idx file and show the data on the page instead of getting it from the actual db server.

No i did not miss it. So my answer is still the same. Do you not understand my answer?
|

|

well, I know that I can read the file like any other file. but I don't know how to read the data from idx file along with its schema. In short I am looking for way to connect to idx files using username and password, if you can give any tip that will be good.

Since you didn't specify I am guessing you mean the Database username and password, is that correct?
If so, in your last post you said this:
SABhatti wrote: instead of getting it from the actual db server.
So you want to get it without using the database server by using the database server, is that about it? 
|

I think the problem is that Mike knows that the OP doesn't know. You know? 
It's like trying to open an Access database without the Jet Database Engine installed. Good luck with that...

let me give u some detail, you might have an idea that some companies develop the page, an activeX, and made a CD along with a .dat and .idx file. Now the end users install the application on their machines, use that page to validate some data e.g. some company name against the CD, the page uses the activeX control to validate information entered by the user against the idx file on the CD and show results, if any, on the page. All this is done through the activeX control which reads from the idx file on the CD. I want to know how to validate/read the information from the IDX file? hope you understand my question now.

I am working with Visual Studio 2005 in C#. I would like to programatically create Word documents. That is, I would like to access the Word object model.
Can I do that with VS 2005? I am reading something about Visual Studio Tools for Office. Do I need that? Or can I just use VS 2005.
Are there class libraries I need to obtain?
Thanks,
Mark

I could be wrong here, but I don't think you need VSTFO to work with office and VS 2005. Just make a reference to the Word object library and go to town.

You are write, you just need to add reference to the Word Object Library.

Hi,
A datagridview is re-populated from a datatable every so often, i.e. every 10 seconds. I am using a timer to trigger the re-population.
Now I would like to move a step forward by checking which cells have changed.
I would like to know which cell(s) have changed so that particular cell gets a new colour for a few moments.
For example if the data in column 5, row 2 has changed then that cell changes colour for a few seconds and the same for any other changed cells.
This is basically a realtime application to show the changes as they happen.
How does the datagridview allow for such a task?
Thanks
