AFAIK the situation is the same on Vista and Windows 7, and will continue to be so on newer versions of Windows:
- a lot of directories cannot be modified by a regular user; those include the top-level directory of your system partition (usually C: ) and all important directories such as /Windows, /Windows/system32, and /Program Files.
- as Michel said, you need an administrator account AND an app "running as administrator" so get over those restrictions.
What should work though is access to a number of special folders intended to hold your app's settings and local data, and other things like that. Have a look at Environment.GetFolderPath() and Environment.SpecialFolder
Within such directories, one usually creates a hierarchy of folders, so a typical sequence would be:
string fileSpec=Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)+
@"\companyName\appName\logfile.txt";
string folder=Path.GetDirectoryName(fileSpec);
Directory.CreateDirectory(folder);
StreamWriter writer=File.CreateText(fileSpec);
...

Parallel.For is part of .NET 4.0, that uses a CLR version different from .NET 3.5.
So you can't use Parallel.For or any 4.0 new feature in a 3.5 or older project.

Hi,
I need a way to check which URL's are available on a specific name server, so which urls are registered there. How can I do this?
In Word you can only store 2 bytes. That is why I use Writer.
|
|
|
|
|
name servers don't contain urls they contain names which can be expanded to fqdn's. You access these names through your favorite dns client (nslookup) for instance, and issue a list command. The administrator of the dns server will probably have disallowed this, because it's a cheap trick used by amateur hackers to discover addresses on networks. If you explain to us what your final purpose is, and persuade us that your intentions are legal, we MIGHT explain some more.

Hi
Im having a problem making the background of a label transparent. I have a label on top of a picturebox and I make the labels parent the picturebox. I also set the labels backcolor to transparent. For some reason the label just disapears when I do this. Does anyone have any ideas?
Thanx
|
|
|
|
|
Try by setting the textbox's parent to the picture box and also by bringing the label to the front.
Something like
Label1.Parent = PictureBox1;
Label1.BringToFront(); .
|
|
|
|
|
Setting the background to Color.Transparent tells the label control to inherit the background properties of it's parent container. It does NOT make the background transparent.
In order to do what you want, you'd have to create your own label control and render it yourself. Your not the first person to want to do this. There are a ton of examples of doing a true TransparentLabel ono the web. All it takes is a little Google to find them. ".net transparent label[^]"

Hi Programmers,
I am rewriting some of my COM Server (Out proc) executable to .Net enviornment.
I havn't found any clue for same, I have googled for same, but everytime I encountered IN_PROC DLL only. might i am searching from wrong keyword.
Actually I needed executable, who expose it's class or interface to dot net application and work accordingly. I have found workaround using IPC DotNet Remoting. i.e. creating class library as proxy and subscribing event in both Client and outproc exe, but it is not full proof.
So please help me if you know something in this reqards
Thanks

There is an image capturing device which outputs images in wmf. This image is directly stored in the db. These images are supposed to appear on web page (in IE). Only some of the images appear; others don't. When we investigated the problem we observed various things:
a) Those problematic images don't appear visible on the web page, but they are still there! If you right click the image and try to save it on your hard disk from IE browser, you get a file.
b) This file is viewable via desktop image viewers like Microsoft Picture Viewer.
c) We can view this image if we convert the file into jpeg.
The jpeg alternative seem viable, but its simply too much processing on the web server if we adpoted that approach. Its only that some of these images have this problem. We have millions of records of data with images. We figure only 10 % of images do have the issue.
Is there a way to detect such problematic wmf files?

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
I searched a lot in google but not get the ans!
So please Help!

In your project go to "References" and delete any reference which have any concerns with "Visualizers".
It will work, because updates have been done on your system with visualizers components, like microsoft updates, so deleting this reference which references to new type of datatables and datasets <Template> should do the job.
Let me know if i can help in any other way.
Hope it helps.

I am building a project. It will have a main menu/GUI from which many application/options will be "spawned."
What is a good way to build the main menu so as to allow someone to add an app without having to recompile the main menu?

If the "applications/options" are just separate EXE's, this is very easy. You keep an XML configuration file that dictates what the menu looks like and which EXE each option opens. You then dynamically build the menu based on the XML file. By loading the XML configuration into memory into a class, you can then keep track of which EXE to launch when a particular menu option is chosen.
If you want to be a little more flexible, you can have the XML file specify 1) the menu layout 2) the DLL to load 3) the method on the DLL to call. You may need other info, such as the class and the namespace. You will then use Reflection to dynamically load the DLL and call the method on the class indicated by the XML configuration. If you want to go that route, start here (this would be a plug-in system, as was suggested by the poster above).
You could also go a third route. You could have your main app be an EXE, then have a class in a different project that dictates the menu handling. It could return a menu object, as well as all the event handling (e.g., load a particular EXE when a menu item is clicked). Your main EXE would call that DLL to ask for the menu. You would then only have to change that DLL whenever you wanted to add items to the menu. That is a recompile, but only of part of the application.

Thank you and PIEBALDconsult. Very good ideas.
Good starting places.
