It's the exact same situation. It cannot be relied upon to determine who is logged in, if anyone. Also, since XP/Vista/7 can have multiple people logged in at the same time, who's the one at the console?? There's no way to tell. Also, it's not just a user account that's logged in. There are also built-in accounts that are being used, such as Local System, Network Service, Local Service, ... Are you going to needlessly attempt to change those accounts too??

That's why I said the best place to use this would be a user app launched out of the Registry's Run key, not a service. That way, the app runs as the user, only when a user is logged in, and doesn't have to worry about figuring out who's logged in.

Well, I would start by getting a good book on the programming language you are trying to learn. Importing and using DLLs is not exactly a step after Hello World.

I suppose by "importing a dll file" you mean that you want to use that Dll in your application. In order to do that you need to reference the Dll in your build (if the Dll is a .NET Dll) or you need to load specific functions from the Dll via P/Invoke (if it is a native - that is non .NET Dll).
Either way I suggest you look for a Dll tutorial if you are new to this.
You should be able to find information on Codeproject searching for P/Invoke (short for Platform Invoke) or looking for some basic C# tutorials which probably also explain usage of Dlls.

Hi All,

I have .Prn file which was generated out of PCL printer.I need to find a string in that file and then I have to replace it with another string.
Iam able to do it by using stream writer,streamreader,Binary reader,binary writer and file streams.

But if gave a print(LPR)for it, it get failed and giving me syntax error as Illegal tag.

If I print original file it is printing very well.
I came to know that while writing it has lost some of its originality ,so it was failed

Please help me

Thanks in advance

Thats probably whats wrong then. Either the value you are replacing with is illegal OR you are replacing something you didn't mean to. Why not save both the original and your new version to disk and compare them - there are loads of free utilities to compare files.

Hi,

Thanks for the reply,

The original file size is like 16k, after the editing it becoming as 22k..
more over it is not normal file,It is a file generated by PCL printer.
So may be during the conversion it is losing printer supported font.
so that's the reason printer cannot understand the file(after editing)to print.so it gives syntax error as Kernel and Illegal tag error.

I even cannot compare both file because the file is generated by PCL printer which has some non-readable data

I have no clues to overcome this problem

kindly help me

So basically what you are doing has corrupted it.

balu12345 wrote:

Yes, so unless you know the format of the file you will mess it up.

Ther eis no such thing as unreadable data. Use a hex editor to compare, there are plenty freely avalable.

It does beg the question though, why do you have to change the PCL file rather than the original data.

HI,

i have a strange problem:

i have a datagrid view bound to a table.
when i edit a cell content i press a button to save this changes like this :

TA_Users.Update(dS_StationManager.T_Users);
dS_StationManager.T_Users.AcceptChanges();

THIS WORKS FINE.
now i've decieded to removw the button so that the changes will be saved without the user pressing the button.

i've tryied copying this two code lines

TA_Users.Update(dS_StationManager.T_Users);
dS_StationManager.T_Users.AcceptChanges();

to diff datagridview events like :
1. dgvUsers_Edit_CellValueChanged
2. dgvUsers_Edit_CellEndEdit

but nothing happens, the database does'nt change

Help Req
THANKS Smile | :)

Are those events actually tied to the delegate?

Dont you think you need to try the event dgvUsers_SelectedIndexChanged.

I have tried that in my code. It was working.
Try to update the database after you leave that row . .

Problems with Webcam Capture

Hi,
I've some problems with my Webcam_Capture-Class. My webcam can capture up to 90 frames per second, but in my program i've just 9-11 fps. The Class' name is Webcam_Capture and i've downloaded it from codeproject.
In the class there's a timer so I can set the "TimeToCapture_milliseconds". I can also set the Frames. I want about 20 fps, but that's impossible. The processor time is about 40%, so that can't be the problem.

Do you have any idea to solve this problem?

Thanks and greetings
shainsen

What do you mean impossible? The library won't accept such a value or is that too strenuous for your system?

Can you reference the article from which you got the class?

Hmm it was not from codeproject but from here:
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=1339&lngWId=10[^]
I think it's because of the library! I've tried only to load a webcam image, but I just had 10 fps in my form. It's not to strenuous for my system, i've only 40% processor time needed by the program.

Greetings shainsen

How to check/control the url which WebBrowser's will navigate it (WebBrowse in Windows App.)

Member 465172910-Mar-09 22:58

Hi all,

I'm using (trying to use) webBrowser control in windows application.

when a user comes default web site is www.abc.com. User can select some transaction and they will be able to what they want.

What I want to do is, when user click ads which are on the website I should not navigate webBrowser, I should not allow to do that.

So I have done something like;

private void webBrowser_Navigating(object sender, WebBrowserNavigatingEventArgs e)
        {
            // check the URL if allowed or not.

            Uri u = webBrowser.Url;
            string ap = u.AbsoluteUri;

            for (int i = 0; i < App.IzinliURL.Length; i++)
            {
                if (ap.IndexOf(App.IzinliURL[i]) == -1) // if it is not allowed
                {
                    webBrowser.Stop();

                    break;
                }
            }

            // new url which I'd like to set but it does not work.
            Uri newUri = new Uri("http://www.google.com.tr");
            webBrowser.Url = newUri;
            webBrowser.Navigate(newUri);
        }

What I have to do.

Many thanks.
