So I am having a problem. I generated about 100 ISO's files of my movies so I can stream them to my TV. Well now I find out I dont need them in ISO, I need AVI. I am trying to open the ISO and the tool that was used created 2 versions of the same file in the same folder. 1 with 0 bytes and 1 with full bytes. Now here is my question from a C# point of view. I am mounting the ISO as a Drive in Windows and copying all but the 0 byte file out. Works fine in Windows. I want to automate this by having c# Mount the Image and copy the files out. I use the System.IO.Directory.GetFiles and build a array of files. When I go through the array to copy the files, I reference by filename which always get the 0 byte file and not the correct file. I cant delete the 0 byte file as it gets mounted as a CD which is read only. Is there any way to reference a file by some internal ID rather than filename in c#?
private void button1_Click(object sender, EventArgs e)
{
List<string> sFilestoProcess;
List<string> sCopyFiles;
sFilestoProcess = GetISOtoProcess();
foreach (string sFile in sFilestoProcess)
{
Mount(sFile);
sCopyFiles = GetValidFiles();
}
}
private List<string> GetISOtoProcess()
{
List<string> Files = new List<string>();
foreach (string sDirectory in System.IO.Directory.GetFiles(@"D:\"))
{
Files.Add(sDirectory);
}
return Files;
}

I don't have a direct response for getting the files, but is that pseudo-code or something you are working with? I was wondering if you have code for the Mount() method.

No one is going to audit all that unformatted code, (no one will probably do it even if you used the pre tags like you're supposed to)
Post specific issues, not a 'here is my project, fix it' post.

Did you actually READ your post after you hit "Post Message"?? Do you really think anyone is going to scroll through all this empty space? Would you mind cleaning this up so it's readable?

My eyes! Please, format your code and put it in a <pre> block.

Especially on weekends i can't read this type of complex code.
Try 2 give code snippets which is well formatted(even having some format) or about the actual problem.

Hello,
I have one server and 5 clients. I want to write a program in c# on server machine to find out at what time user logged in , logged out; what was the total data uploaded/downloaded by user and what are the software installed or uninstalled by user for that session.
for 5 clients , IP will be provided and the program should return 5 log files (one per client machine) giving details for the above mentioned parameters.
Any help in this regard is highly appreciated.
Thanking you in anticipation.

That information can be obtained by browsing the EventLog[^]. Provided that you have the appropriate rights within your network to do so.
Ajay Kewale wrote: what was the total data uploaded/downloaded by user
That's going to be trickier. Most applications don't tell Windows how much they download, so you'd have to dive a level deeper. Perhaps you can use the Firewall API[^] to do so.
Ajay Kewale wrote: what are the software installed or uninstalled by user
The easiest way is to write a small daemon that makes a list of the installed applications[^] when the session starts, make a second list when the session ends, and compare them. Any modification, even individual service packs, will be listed. There should be entries like;
"Update for Microsoft Visual Studio Web Authoring Component (KB945140)"
The hard way is to write a Windows-service, looking for various installer-processes. Either way, you won't find any PortableApps[^] with these methods.

Aw, so without installing any code on the clients at all? You can read the Registry remotely to obtain the list of applications, again, if you have sufficient rights on your domain. I doubt however that the amount of transmitted data can be remotely retrieved.

Hi,
I have a desktop application which takes photos and upload to a web server. I am using HttpWebRequest and HttpWebResponse classes to make request and get response. I am showing progressbar on the UI to show upload process. Everything is working fine. But since I am getting the status, when one file gets uploaded completely, my progressbar looks frozen, till the complete file upload.
var responseFromServer = ServiceRequest.GetResponsePhoto("AddPhotos", "ServiceInstances", photoToUpload, serviceInstanceID.ToString());
var response = responseFromServer.Deserialize<Dictionary<string, object>>();
bool success = (bool)response["success"];
ServiceRequest class takes care of making a request and getting response from server.
HttpWebResponse.GetResponseStream method gives response for the complete upload of one file. I want to know if there is any way I could able to know intermediate upload steps which I can show on the progressbar which makes UI more interactive.
Any help or any sample will be greatly appreciated.

This[^] is for download but you may be able to use for upload also.
only two letters away from being an asset
|
|

|

Nope. Not using what you have now. Since all of the code blocks until the transaction is complete and none of the methods reports at status information, you'd have to scrap all of your upload code and rewrite it to do this yourself. Even the Async methods don't report status, but they will allow you to keep your form responsive while the upload is going on.

Thanks Mark and Dave,
Mark, I think the link is not going to help, since I am uploading to the server, I have no way to find out how much data is uploaded to the server in intermediate state.
Thanks anyway,
Veena

Hi friends.
I've put an UnboundString field in footer (Section4) of a Crystal Report.
I'm gonna fill it with a summary of Section3, but I don't know how I can access it in C# !
Could you please guide me , how I can access it ?
Thanks in advance.

Is it possible to play a video file on a specific area on the form using code code without placing a control to contain the video file?
any C# example plz?
Thanks..

You would need a control that has the ability to play the video...

I want to know your advise plz..
I have a software and I don't want use to be able to use it once downloading it so I though of having an activation process first..
what do you think?
and what's the best way to do it using C#?
and how to make sure another person who will download the same software won't be able to use using an activation code givento another customer?
|
|
|
|
|
There is no fool-proof way to ensure security in the manner you are talking about.
The best way, based off what you say is communication to a database to ensure that an activation code hasn't been used more then once, but then you limit your software in the regards that a host computer must have an internet connection to activate the software.
Then you would also have to check consistently if the activation code is correct for each use of the application.
What if a client does not have an activation code?
And you're ignoring that all .Net applications compile to MSIL, which isn't that hard to go through using Reflector. If you build in an algorithm to generate an activation code, if determined enough a user might be able to generate his own activation codes.

This question has been asked and answered so many times in this forum that it is impossible to believe that you have even tried to search for an answer.
Do not be so lazy! Do your own research.

How can I customize the Crystal Reports Viewer statusbar to have some other controls on it, e.g. comboxbox, calendar, etc..
|
|
|
|
|
By doing some research for yourself.
Try Googling crystal reports viewer statusbar
This site is really not the place to try to get a cheap tutorial in how to program. Do your research, try for yourself and then, and only then, ask here with specific problems, showing what you have tried and what and where the error is.

Is it possile to use the data MDF file on the client when distributing my software installing the SQL Server on the client machine? just like a stand-alone database file?
|
|
|
|
|
No, you can't. What's going to read/write the data in the file then? At a minimum, you'd have to use SQL Server Express Edition.

I have a (Daily Report) shown on Crystal Report Viewer and I want when the user right click anywhere on the viewer to display a popup calendar so user will select another day to view its report?
