Using Vista Home Premium - everything up to date.
I'm the Admin and sole user of this machine.
Downloaded C# Express.
Tried to create new project and got this error msg: "Required registry access is not allowed"
Could not create the project.
Reinstalled C# and tried again. Same result.
Been using VB.net Express since '05 and never saw this error before.
Any ideas?

Hi,
Visual Studio Express edition works fine for me under Vista Home Premium (C#, VB.NET, C++/CLI).
I googled Visual "Required registry access is not allowed" and found some 12 hits indicating you are not alone, unfortunately the promising Microsoft links all were broken...
There was one hint: disabling UAC, then re-enabling UAC (may take two reboots); everything else was changing lots of things in the registry...

Tried playing with the UAC but the problem persists. I also found a lot of broken links in the Questions section of the C# documentation.
From what I've seen, MS is as clueless about it as I am. Not good.

According to the title bar of C#, that's what I'm doing - it says "(Administrator)".

I have some place in my code that i update my database(using Access db).
After i did this update - i try to get from some other place in my code the fresh data from this database.
For some reason i see that i get the old database data (i get the data before i update this database). But when i add some sleeping time (Thread.Sleep(5000)) before getting the fresh data i see that the data was update correctly.
How can i fix this problem ?
How can i know if the update of the database table was done ?

Are you using a separate thread to update the database.
If so, Use ManualResetEvent object to Set when update is successfully done.
And in the main thread use WaitOne function to wait until the child thread finishes its job.
You can also use Thread.Join to do this as well.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

No,
In my application i have only one thread, so its does not look like thread synchronize problem.

No - as the program will be in use!

As Dave said - no, but why on earth would you want to do this? The only reason I can see for this would be to try to put something malicious on a machine which removes itself when it's completed it's nefarious purpose. As you earlier posted about wanting to write a key logger, I'm highly suspicious of what you are hoping to accomplish.

Errrm. You did see the honking great bit of text at the top that said this was the C# forum didn't you? I mean - I can see that it would be easy to miss, what with it being twice as big as the rest of the text and green. I mean, c'mon; couldn't they have made it any more apparent that this section was about C# code and nothing whatsoever to do with asking questions about commercial applications?
Would you like to go away now, or shall I mock you some more?

Hello,
I have 3 types of resources embeded in my executable :
html, jpg and pdf. I also have a listbox, and I want whenever a user sleects a different item, to display it in a web browser.
I have no problems doing that to HTML files, but with the other one, it's a different thing and I hope someone can help me do this.
First, I want to say that I don't want to save the resources locally and after that load them in the browser, because I don't want users to see them.
I am using this to view the html :
<br />
Assembly assembly = Assembly.GetExecutingAssembly();<br />
webBrowser1.DocumentStream = assembly.GetManifestResourceStream("ebook.index.html");
If I try to do the same thing to the pdf or jpg, it simply shows me the binary data of the files, it does not display them in the browser.
Is it possible to make the visible in the browser, directly from the assembly ? What are my options ?
Thank you

Hi,
I haven't done this myself, but the way I understand it you must also set the WebBrowser.DocumentType (try "application/pdf"); that should allow you to view a PDF document (or any image) as a web page.
You probably also want images inside web pages, so have a look at embedded images[^].

Hello,
Thank you for the quick reply but unfortunatly the DocumentType is read only 
Any other ideeas ?
Thanx
|
|

|

Yes, you are right.
And the data scheme[^] is usable only for small amounts of data, hence small images only, no PDF documents.
I guess the next logical approach is to come up with a simple HTTP server that can provide HTML and PDF; then embed that in the app, andmake the WebBrowser navigate to it.
This seems to be a candidate: Sample HTTP Server Skeleton in C#[^]

Hi,
I now have a simple embedded HTTP server working based on the article I provided a link to.
It gets a PDF document somewhere (from a file!), then serves that to its client, which can be either a regular browser (e.g. FireFox) or a WebBrowser. It still needs a lot of clean-up though, but I wanted to confirm you can make it work.

Hi
I want my application to update itself. As far as I know we can't do this in C# ( or any other language -without workarounds- ) because a file can't change itself while running.
I tried using another method which first downloads the newer executable, creates a batch file which waits for a while for the application to terminate then deletes the main app and replaces it with the newer one, then launches it.
But there is something wrong here I think. The batch file doesn't do everything correctly. Sometimes it doesn't delete itself or the update file, or sometimes newer does anything.
Class:
class updater
{
public string UpdaterURL = null;
public string LocalUpdaterLocation = null;
public int ErrorCounter = 0;
public void Download()
{
if (ErrorCounter == 0)
{
WebClient wc = null;
try
{
wc = new WebClient();
wc.DownloadFile(UpdaterURL, LocalUpdaterLocation);
}
catch { ErrorCounter++; }
finally { if (wc != null) wc.Dispose(); }
}
}
public void CreateBatchFile()
{
if (ErrorCounter == 0)
{
string AppPath = Application.ExecutablePath.Replace(Application.StartupPath, "").Replace(@"\", "");
StreamWriter sw = null;
try
{
sw = new StreamWriter("update.bat");
sw.WriteLine("@echo off");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("ping 127.0.0.1 -n 2 -w 1000 > nul");
sw.WriteLine("deleteexe:");
sw.WriteLine(@"del """ + AppPath + @"""/Q/S>nul");
sw.WriteLine(@"if exists """ + AppPath + @""" goto deleteexe");
sw.WriteLine("rename " + LocalUpdaterLocation + " " + AppPath);
sw.WriteLine(AppPath);
}
catch { ErrorCounter++; }
finally { if (sw != null) { sw.Close(); sw.Dispose(); } }
}
}
public void StartUpdating()
{
if (ErrorCounter == 0)
{
Process prc = new Process();
prc.StartInfo.FileName = "update.bat";
prc.StartInfo.ErrorDialog = false;
prc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
prc.Start();
Environment.Exit(0);
}
}
}
How I call it:
updater upd = new updater();
upd.UpdaterURL = "http://.../update.exe";
upd.LocalUpdaterLocation = "update.exe";
upd.ErrorCounter = 0;
upd.Download();
upd.CreateBatchFile();
upd.StartUpdating();
Thanks in advance,
Can
