I was postulating here in the forum for sometimes that if you want some functionality of a certain library of .Net framework, you can install it on your machine and explicitly reference to that library. So you'd be using .Net 1.1 for everything else, yet enjoy this new feature of .Net 2.0 or even 3.0.

Sure it won't. You have to put this code in a recursive function and recall it each time.

You are enumerating Directories. I guess a TreeView would do the job.

Thank you. Could you tell me how I display the results to the web, instead of using Console.write? Is there another class output specific for a web app?

Regards

The best vehicle for displaying this in a web is using a treeview control.

public void MyForm_Load(object sender, EventArgs e)
{
     InitializeComponent();    
     RecursiveGetDir(@"C:\Windows", myTreeView.Nodes);    
     Console.Read();
}

static void RecursiveGetDir(string cDir, TreeNodesCollection nodes)
{    
     DirectoryInfo[] dirs =  new DirectoryInfo(cDir).GetDirectories();     
     if (dirs.Length > 0)    
     {        
          foreach(DirectoryInfo dir in dirs)        
          {            
               TreeNode node = new TreeNode(dir.FullName);
               nodes.Add(node);           
               RecursiveGetDir(dir.FullName, node.Nodes);        
          }    
     }

i am calling a web service method in my windows application
the method returns xml file,i would like to set the Connection
timeout for my web service to 20 minutes,
and the counter is reset to zero everytime you Access any of the functions on the web service
So if you access the web service again within 20 minutes you dont need to log on again,
can any of you refer me to articles or samples

thanks

regards paula

Hi Paula,

20 minutes sounds like a very long timeout for a webservice. Even stranger is that you want it to reset it when accessing other methods. Why would you want to do this? Are you trying to fake events?

One way to go might be (in .NET 2.0) to use the asynchronous methods of the webservice proxy. You can then easily cancel your original call and re-issue it when you call any other method, but this is not good if it really does take say 15 minutes to return the data you asked for, as you'll keep aborting it and restarting.

Rob Philpott.

Hello

For sure you application will keep running.

Either:
1- Make you Thread.IsBackground = true
2- Or Terminate your thread in the Form_Closing event.

AFAIK there is no equivalent for StrReverse but you can use String.LastIndexOf method to get the index of the last occurence of a substring.
Or for the given problem use Path.GetFileName(strFileNamePath).Length.

for the equivalent of instr look at IndexOf or LastIndexOf.

crazysanker wrote:

You'll have to write that yourself, since there is no percieved commercial need for this.

for ( int i = str.Length-1; i>=0; i-- )
{ 
    rStr += str[i];
}
return rStr;

That is just str.Substr(startPos, len); if I remember my Visual Basic correctly.

Hi I am having trouble trying to display some rows of a html table. I am trying to display the same amount of rows that is in a datatable returned from database. At the moment I have named all rows of table and put in the runat=”server” so I can reference it in the code. This is the code I am using but I get an invalid cast error

//*** work through datatable of drills
for(int rowNum = 1; rowNum<=iSet.Tables[0].Rows.Count; rowNum++)
{
//*** declare founctrl and set equal to a control found with the id
TableRow founctrl = (TableRow)FindControl("row"+rowNum.ToString());

//*** if a control is found
if (founctrl != null)
{
//*** dislay the row
founctrl.Visible = true;
}
}

I am looping throught datatable and tryin to find the rows of html table and make them visible but it crashes on the line that tries to find the tablerow. So im just wondering if there is a better way to go about this or am I making a mistake in this code thanks in advance. Tim

Hi Tim,

I don't know that much about DataTables and the like, but the way you are extracting the row from the table looks highly dubious to me.

Why not do something like:

foreach(TableRow row in iSet.Tables[0].Rows)
{
    row.Visisble = true;
}

.. whether that would have the desired effect of making the row visible or not I'm not sure.

Rob Philpott.

Help file issue

Hi,

I have a complied .chm help file that works fine when run from anywhere on my computer or on another computer when installed as part of the program it relates to.

When I make the chm file available for download and I download it from the website I get the usual warning from the system that it may be unsafe etc. I click on run but then it can't find the actual html files to display.

How do I get around this without creating a whole new .msi file?

Glen Harvy

Nader Elshehabi3-Oct-06 2:12

3-Oct-06 2:12

Hello

I you want to make your chm file optional, you could make it downloadable, and put it in an installer that would look for the path of your already installed application to put it in the same folder. ie.
1- Make you app.
2- Make the installer of your app put the [TARGETDIRECTORY] path in a registry key
3- Make you app look for the chm file in its folder, if not available it should display a polite message that the help file isn't available and you can download it from here.
4- Make another installer -ie. msi- that contains the help file only, and would automatically install it in the program's folder using that registry key.

I hope I got you right.

Regards

Glen Harvy3-Oct-06 4:05

Thanks for your suggestion BUT it's not really what I want.

I don't want to install anything.

I just want a person to be able to download the .chm file, click on it and they can read it.

Glen Harvy

Nader Elshehabi3-Oct-06 4:36

3-Oct-06 4:36

So, you downloaded the chm file to your machine -using save as, not run-, and when you opened it you saw it empty?

Saving to the desktop OR runing it - either way you get the same problem.

I have since found out why - it's a security issue with the OS. MS in their wisdom decided that the user also has to "unblock" the pages manually http://support.microsoft.com/kb/896054.

It seems I will have to make the .chm file an msi file otherwise I will have to have a help file on how to read the help file!

Is it possible to create a help file at complie time that doesn't use html files.

Cheers.
