You should have a non-developer (a configuration manager) who performs the test and production builds. I worked at a place where the first task the testers did was build the code and kick it back if there were problems.

Just all about of my apps I've ever written copy files when needed on demand and nothing else is responsive until a file copy or move is completed. If a lot of files are involved it can take a while before you know it's done. Sometimes, I'll display the pathnames in a status bar, that kind of feedback malarkey.
Programs like 7z, possibly WinRar as well, go through the hoops of uncompressing an archive and when the files/folders are being copied you see the conventional Windows copy file dialog and progress bar. Is there a special API call or trick they they use to do this?

Yes, there are API's that will do this for you, but you could always go the easy way and use the Microsoft.VisualBasic.FileIO namespace and use one of the following methods:
FileSystem.CopyFile(source, destination, UIOption.AllDialogs);
FileSystem.CopyDirectory(source, destination, UIOption.AllDialogs);

I was thinking it might have been functions in shlwapi.dll that had similar options to display a UI for file copy, but my memory must be fading with age

It's in Shell32.dll. I'm pretty sure it's this[^] API.

yup, that'd be it - well done !!

Thanks for the heads-up on the that Pete. A while back I remember sneering at that namespace and the next moment I found it made life easier! I will investigate it once more.

You're welcome. I'm glad that I can supply some aid here.

A little while ago, I see somebody down-voted my original question which was somewhat puzzling given the relevance of what I was asking. It seems you can't please some folks.

I've upvoted in compensation. It seemed to be a fair question to me. If it wasn't, I wouldn't have given a sensible answer.

Thanks for watching my back. You can't be too careful.

The copying code is called on a background thread while the Progress Bar is being updated via the main or UI thread.
Thus, you see the effect of the progess bar incrementing while the file is being copied.

In an existing C# 2008 windows application I am trying to decide how to use the existing application without rewriting it. Currently there is a 'driver C# 2008 windows' program that calls the 'main C# 2008 desktop' application to perform various caLLS to a third parfty web service.
Now I would like to use the 'main C# 2008 desktop' application to be run by users. The users would enter the required paramters in a desktop screen and/or possibly a dos popup window. The application would know who is running the program by the paramters that are passed to the application.
Thus my question is, can a desktop screen and/or a dos popup window show up when users click on the executable? The default would be for the no desktop window to show up when the program is called by the 'driver C# 2008 windows' program.
Thus can you show me code and/or point me to urls that would show me how to accomplish this goal? If my goal not realistic, can you suggest other ways that I can accomplish the add on goal I am trying to acheive?

Errrr, dcof, you're posting under your other account again. Honestly, I don't know why you're still persisting with this architecture. We told you, when you first started posting about this under your many accounts, that it's not a good design and that you should seek to replace the second console application as it's unnecessary. You are tying yourself in knots here, trying to fix this broken application.

i am getting an error: unexpected end of file on the line that contains databaseKeyValue. Not sure why that is the case. Any help will be greatly appreciated.
private static bool addItemsToDrawing(
Visio.Page drawingPage)
{
bool itemsAdded = false;
Array shapeIDs;
addShapesToDrawing(drawingPage, out shapeIDs);
if (shapeIDs != null)
{
for (int index = shapeIDs.GetLowerBound(0);
index <= shapeIDs.GetUpperBound(0);
index++)
{
short shapeID = (short)(int)(shapeIDs.GetValue(index));
Visio.Shape newShape = drawingPage.Shapes.get_ItemFromID(shapeID);
int databaseKeyValue = newShape.get_Cells(_VisioPropCellPrefix + _IDColumn).get_ResultInt((short)Visio.VisUnitCodes.visNumber, 0);
_ItemShapeIndexMap.Add(databaseKeyValue, newShape.Index);
}
itemsAdded = true;
}
return itemsAdded;
}
|
|
|
|

I geuss you mean you get an Exception when running this code? Probably get_Cells() returns an empty result set.
|
|
|
|
|
int databaseKeyValue = newShape.get_Cells(_VisioPropCellPrefix + _IDColumn).get_ResultInt((short)Visio.VisUnitCodes.visNumber, 0);
That's too many statements on a single line. Call a single method per line, and step trough the code. It's probably not one of those methods that causes the exception, but a related event.
short shapeID = (short)(int)(shapeIDs.GetValue(index)); Why cast it to int, if you need a short?

i have designed a table as shown below. the are two literal controls as i am binding the datatable to the literal contol creating a tabular structre in the page load itself. The data is displayed correctly in default.aspx page. i want to export this aspx page to pdf . I using Itextsharp.dll.
On button click i have written code. The PDF is generated but it is getting distorted. Not getting generated as per the displayed aspx page.
Default.aspx and cs file is pasted below.

I suspect iText is choking because of either invalid HTML, or all your nested tables are just too complicated for it. Post the final markup (view source) of your page so we can check it for known iText errors. One unclosed tag will mess it up bad.

I have a requirement where when a button is clicked the app connects to a remote pc and the user can browse to a folder on the c drive then copy a file to their pc (not on a LAN but a remote location)
When using Remote desktop connection the details are (for example)
Computer: abcd.dyndns.org:1234
Username: bob2\apple
Password: password
After doing a bit of research using WMI or Impersonation seems the best options. Here's where I'm at with the Impersonation approach..
[DllImport("advapi32.DLL", SetLastError=true)]
public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType,
int dwLogonProvider, ref IntPtr phToken);
private void button4_Click(object sender, EventArgs e)
{
WindowsIdentity wid_current = WindowsIdentity.GetCurrent();
WindowsImpersonationContext wic = null;
try
{
IntPtr admin_token = new IntPtr();
if (LogonUser("bob2\apple", "abcd.dyndns.org:1234","password",9, 0, ref admin_token) != 0)
{
wic = new WindowsIdentity(admin_token).Impersonate();
File.Copy(@"", @"",
true);
MessageBox.Show("Copy Succeeded");
}
else
{
MessageBox.Show("Copy Failed");
}
}
catch(Exception se)
{
int ret = Marshal.GetLastWin32Error();
MessageBox.Show(ret.ToString(), "Error code: " + ret.ToString());
MessageBox.Show(se.Message);
}
finally
{
if (wic != null)
wic.Undo();
}
}
thanks

Do you need file access to take place in the context of the actual user who is on the web site? Or, is this a situation where access to the web site means access to the files? If you need the Windows admins to control access to these files, then yes you need to use impersonation, but if you don't need that, it would be much easier to just stream the file back over HTTP. In that case file access would be done by the ASP_NET User, so you would only need to grant one user access to the folder. In the impersonation case, you have to add users to groups and whatnot to manage access to that folder.
Streaming a file back is super easy...
var file = File.Open(path);
Response.Clear();
Response.ContentType = "application\xml";
Response.WriteFile(file);
Response.Flush();
Response.Close();
Response.End();

Then hopefully there is also another requirement/assumption that states that the user must have remote access privileges on that computer sufficient to allow that.

please help me i want to create password for my win form and how can i manag it
|
|
|
|

The same way you create any form. Add a label and a text box that has the PasswordChar or UseSystemPasswordChar property. Then use ShowDialog to display the form at the beginning of the application.
Use the best guess
|
|
|
|
|
I think the answer you may be looking for is in the region of encryption and decryption.
Basically it boils down to never storing a clear text password - use something similar to the crypto class described here[^].
